本發明係關於一種開關裝置、及負載控制系統,特別是關於一種控制照明負載等之開關裝置、及使用該開關裝置之負載控制系統。The present invention relates to a switching device and a load control system, and more particularly to a switching device for controlling a lighting load or the like, and a load control system using the same.
作為習知例,例示文獻1記載之開關裝置(參考文獻1日本國公開特許公報第2012-174513號)。此一習知例,構成為切換藉由電力線進行的對負載之電力的供給及阻斷,安裝於嵌入壁面的開關盒內。As a conventional example, the switch device described in Document 1 is exemplified (Reference 1) Japanese Patent Laid-Open Publication No. 2012-174513. In this conventional example, the power supply to the load by the power line is switched and blocked, and is mounted in a switch box that is embedded in the wall surface.
此外,此一習知例,具備繼電器單元、及控制繼電器單元之控制電路。繼電器單元,具有電磁繼電器及半導體繼電器。作為機械式繼電器之電磁繼電器,由接點及激磁線圈構成。接點,作為電力線中單切的常開接點而設置。激磁線圈,與負載(照明器具)並聯而設置。Further, this conventional example includes a relay unit and a control circuit for controlling the relay unit. Relay unit with electromagnetic relay and semiconductor relay. An electromagnetic relay as a mechanical relay is composed of a contact and an exciting coil. The contact is set as a normally open contact in the power line. The excitation coil is provided in parallel with the load (lighting fixture).
半導體繼電器,由開閉部及驅動部構成。開閉部,具有受光型的半導體元件,依據有無來自驅動部的光線而ON/OFF。驅動部,具有發光型的半導體元件,依據自控制電路給予的ON/OFF控制訊號而發光/停止發光。The semiconductor relay is composed of an opening and closing unit and a driving unit. The opening and closing unit has a light receiving type semiconductor element that is turned ON/OFF depending on the presence or absence of light from the driving unit. The driving unit has a light-emitting semiconductor element, and emits/stops light emission in accordance with an ON/OFF control signal given from a control circuit.
亦即,文獻1記載之習知例中,若操作觸控面板等之開關部,則控制電路控制半導體繼電器而驅動電磁繼電器,開啟關閉藉由電力線施行之對照明器具的電力供給。In other words, in the conventional example described in Document 1, when the switch unit such as the touch panel is operated, the control circuit controls the semiconductor relay to drive the electromagnetic relay, and turns on and off the power supply to the lighting fixture by the power line.
而文獻1記載之習知例中,電磁繼電器的激磁線圈,藉由半導體繼電器而連接於與負載相同的電源,故不易發生配線錯誤(操作錯誤)。然而,在將激磁線圈與其他電源連接之構成的情況,有發生配線錯誤的疑慮。而在發生配線錯誤之情況,過大的電流流通於激磁線圈的電流流通路徑,有致使開關裝置故障的可能。In the conventional example described in Document 1, the exciting coil of the electromagnetic relay is connected to the same power source as the load by the semiconductor relay, so that wiring errors (operation errors) are less likely to occur. However, in the case where the excitation coil is connected to another power source, there is a concern that a wiring error occurs. On the other hand, in the case of a wiring error, an excessive current flows through the current flow path of the exciting coil, which may cause the switching device to malfunction.
鑒於上述問題,本發明之目的在於提供一種,抑制因配線錯誤等而發生之故障的開關裝置及負載控制系統。In view of the above problems, an object of the present invention is to provide a switch device and a load control system that suppress a failure that occurs due to a wiring error or the like.

以下,參考附圖,對本發明之一實施形態的開關裝置、與本發明之一實施形態的負載控制系統,詳細地予以說明。另,下述說明內容中,作為負載雖例示照明負載,但負載的種類並未限定於照明負載。Hereinafter, a switch device according to an embodiment of the present invention and a load control system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the lighting load is exemplified as the load, but the type of the load is not limited to the lighting load.
本實施形態之負載控制系統,如圖6所示,具備:開關裝置1、以及3個遙控繼電器2(2A、2B、2C)。然而,下述說明內容中,在區分3個遙控繼電器之情況給予「2A」、「2B」、「2C」的符號,在未區分3個遙控繼電器之情況給予「2」的符號。同樣地,在區分3個照明負載之情況給予「4A」、「4B」、「4C」的符號,在未區分3個照明負載之情況給予「4」的符號。As shown in FIG. 6, the load control system of the present embodiment includes a switching device 1 and three remote control relays 2 (2A, 2B, and 2C). However, in the following description, the symbols "2A", "2B", and "2C" are given when three remote control relays are distinguished, and the symbol "2" is given when three remote control relays are not distinguished. Similarly, the symbols "4A", "4B", and "4C" are given when three lighting loads are distinguished, and the sign of "4" is given when three lighting loads are not distinguished.
遙控繼電器2為習知之裝置,係以主接點20、繼電器線圈21、輔助接點22、二極體23與24、以及1對訊號端子(第1訊號端子251、第2訊號端子252)等構成。主接點20,插入於自電源(交流電源3)對照明負載4供電的供電路。繼電器線圈21的一端與輔助接點22之共通端子相連接。另,繼電器線圈21的另一端與第1訊號端子251相連接。The remote control relay 2 is a conventional device, which is a main contact 20, a relay coil 21, an auxiliary contact 22, diodes 23 and 24, and a pair of signal terminals (a first signal terminal 251, a second signal terminal 252), and the like. Composition. The main contact 20 is inserted into a supply circuit that supplies power to the lighting load 4 from the power source (AC power source 3). One end of the relay coil 21 is connected to a common terminal of the auxiliary contact 22. Further, the other end of the relay coil 21 is connected to the first signal terminal 251.
輔助接點22之一方的切換端子與二極體23的陽極相連接,輔助接點22之另一方的切換端子與二極體24的陰極相連接。輔助接點22,構成為與主接點20連動,例如,在主接點20為開路狀態(參考圖6)時其共通端子與二極體23側之切換端子相連接,在主接點20為閉路狀態時其共通端子與二極體24側之切換端子相連接。另,二極體23的陰極及二極體24的陽極,與第2訊號端子252相連接。此外,雖圖示中省略,但在一方之二極體23的陽極-陰極間插入電容器與電阻之串聯電路(微分電路)。The switching terminal of one of the auxiliary contacts 22 is connected to the anode of the diode 23, and the other switching terminal of the auxiliary contact 22 is connected to the cathode of the diode 24. The auxiliary contact 22 is configured to be interlocked with the main contact 20. For example, when the main contact 20 is in an open state (refer to FIG. 6), the common terminal is connected to the switching terminal on the side of the diode 23, and at the main contact 20 When it is in the closed state, its common terminal is connected to the switching terminal on the side of the diode 24 . Further, the cathode of the diode 23 and the anode of the diode 24 are connected to the second signal terminal 252. Further, although not shown in the drawings, a series circuit (differential circuit) of a capacitor and a resistor is inserted between the anode and the cathode of one of the diodes 23.
若對訊號端子間施加直流電壓(亦即,若對第1訊號端子251與第2訊號端子252之間,以使第1訊號端子251成為較第2訊號端子252更為高電位的方式施加直流電壓),則激磁電流以第1訊號端子251→繼電器線圈21→輔助接點22→二極體23→第2訊號端子252之路徑流通,故主接點20自開路狀態切換為閉路狀態(亦即,主接點20成為ON)。一旦使主接點20為ON,則輔助接點22(即輔助接點22之共通端子)與主接點20連動而切換至二極體24側,故激磁電流變得無法流通於繼電器線圈21。然而,遙控繼電器2係具有永久磁石之閂鎖型的繼電器,故激磁電流停止後主接點20仍維持於閉路狀態。When a DC voltage is applied between the signal terminals (that is, a DC is applied between the first signal terminal 251 and the second signal terminal 252 so that the first signal terminal 251 becomes higher than the second signal terminal 252. Voltage), the excitation current flows through the path of the first signal terminal 251 → the relay coil 21 → the auxiliary contact 22 → the diode 23 → the second signal terminal 252, so the main contact 20 is switched from the open state to the closed state (also That is, the main contact 20 is ON). When the main contact 20 is turned ON, the auxiliary contact 22 (that is, the common terminal of the auxiliary contact 22) is switched to the side of the diode 24 in conjunction with the main contact 20, so that the exciting current cannot flow to the relay coil 21. . However, the remote control relay 2 is a latch type relay having a permanent magnet, so that the main contact 20 is maintained in a closed state after the excitation current is stopped.
此外,若對訊號端子間施加相反極性的直流電壓(亦即,對第1訊號端子251與第2訊號端子252之間,以使第2訊號端子252成為較第1訊號端子251更為高電位(相反極性)的方式施加直流電壓),則激磁電流以第2訊號端子252→二極體24→輔助接點22→繼電器線圈21→第1訊號端子251之路徑流通,故主接點20自閉路狀態切換為開路狀態(亦即,主接點20成為OFF)。一旦使主接點20為OFF,則輔助接點22與主接點20連動而切換至二極體23側,故激磁電流變得無法流通於繼電器線圈21。然而,在激磁電流停止後主接點20仍維持於開路狀態。Further, when a DC voltage of opposite polarity is applied between the signal terminals (that is, between the first signal terminal 251 and the second signal terminal 252, the second signal terminal 252 becomes higher than the first signal terminal 251. When the DC voltage is applied in the opposite polarity, the excitation current flows through the path of the second signal terminal 252 → the diode 24 → the auxiliary contact 22 → the relay coil 21 → the first signal terminal 251, so the main contact 20 The closed state is switched to the open state (that is, the main contact 20 is turned OFF). When the main contact 20 is turned off, the auxiliary contact 22 is switched to the side of the diode 23 in conjunction with the main contact 20, so that the exciting current does not flow through the relay coil 21. However, the main contact 20 remains in the open state after the excitation current is stopped.
一旦使遙控繼電器2(之主接點20)為ON,則自交流電源3通過遙控繼電器2對照明負載4供給交流電力,使照明負載4為ON(點燈)。此外,一旦使遙控繼電器2(之主接點20)為OFF,則成為未自交流電源3通過遙控繼電器2對照明負載4供給交流電力,而使照明負載4為OFF(熄燈)。然而,本實施形態之負載控制系統中,將與遙控繼電器2A、2B、2C不同的開關5A、5B、5C,分別插入於自交流電源3對照明負載4A、4B、4C供電的各供電路。此等開關5A、5B、5C,例如為嵌入配置於壁面的壁面式開關,構成為在每次操作操作手柄時使接點開閉。亦即,在遙控繼電器2為ON狀態時,藉由操作開關5A、5B、5C而各別地開啟/關閉各照明負載4A、4B、4C。此外,開關5A、5B、5C之接點關閉時,因應遙控繼電器2的ON/OFF而開啟/關閉照明負載4。When the remote control relay 2 (the main contact 20) is turned on, AC power is supplied from the AC power supply 3 to the illumination load 4 via the remote control relay 2, and the illumination load 4 is turned ON (lighting). When the remote control relay 2 (the main contact 20) is turned off, the AC power is not supplied from the AC power source 3 to the illumination load 4 via the remote control relay 2, and the illumination load 4 is turned off (turned off). However, in the load control system of the present embodiment, the switches 5A, 5B, and 5C different from the remote control relays 2A, 2B, and 2C are respectively inserted into the respective supply circuits that supply power to the illumination loads 4A, 4B, and 4C from the AC power supply 3. The switches 5A, 5B, and 5C are, for example, wall-mounted switches that are embedded in the wall surface, and are configured to open and close the contacts each time the handle is operated. That is, when the remote control relay 2 is in the ON state, the respective lighting loads 4A, 4B, and 4C are individually turned on/off by operating the switches 5A, 5B, and 5C. Further, when the contacts of the switches 5A, 5B, and 5C are turned off, the lighting load 4 is turned on/off in response to the ON/OFF of the remote control relay 2.
其次,對本實施形態之開關裝置1加以說明。Next, the switch device 1 of the present embodiment will be described.
本實施形態之開關裝置1,如圖1所示,具備控制部10、操作部11、供電部12、電源部15、恆定電壓電路16、以及顯示部17。As shown in FIG. 1, the switch device 1 of the present embodiment includes a control unit 10, an operation unit 11, a power supply unit 12, a power supply unit 15, a constant voltage circuit 16, and a display unit 17.
控制部10,例如係以微控制器(例如Microchip Technology Inc.製 PIC16F1503等)、及藉由微控制器執行之程式構成。The control unit 10 is configured by, for example, a microcontroller (for example, PIC16F1503 manufactured by Microchip Technology Inc.) and a program executed by a microcontroller.
電源部15構成為,將自交流電源3供給的交流電力(例如實際值為100~120伏特的交流電力)轉換為直流電力(例如24伏特的直流電力)。電源部15,將一定的直流電壓作為輸出電壓而對供電部12供給。此等電源部15,例如以習知之絕緣型的開關電源電路實現。The power supply unit 15 is configured to convert AC power (for example, AC power having an actual value of 100 to 120 volts) supplied from the AC power supply 3 into DC power (for example, DC power of 24 volts). The power supply unit 15 supplies a constant DC voltage as an output voltage to the power supply unit 12. These power supply units 15 are realized, for example, by a conventional insulated switching power supply circuit.
恆定電壓電路16構成為,將電源部15的輸出電壓(24伏特的直流電壓),降壓為低電壓(例如5伏特)的直流電壓並使其穩定化。此等恆定電壓電路16,例如以習知之降壓截波電路與3端子調節器實現。另,下述說明內容中,將恆定電壓電路16的輸出電壓稱作控制電壓。控制電壓,輸入至控制部10之電源端子。The constant voltage circuit 16 is configured to step down and stabilize the output voltage (24 volt DC voltage) of the power supply unit 15 to a low voltage (for example, 5 volts) DC voltage. These constant voltage circuits 16 are implemented, for example, by conventional buck chopper circuits and 3-terminal regulators. In the following description, the output voltage of the constant voltage circuit 16 is referred to as a control voltage. The control voltage is input to the power supply terminal of the control unit 10.
操作部11,由瞬時型的按鈕開關構成,對兩端施加控制電壓,高電位側的一端與控制部10的輸入埠之一相連接。亦即,控制部10的輸入埠,在未操作操作部11時成為高位準(控制電壓),在操作操作部11時成為低位準。因此,控制部10,藉由該輸入埠成為低位準而自操作部11接收操作訊號。The operation unit 11 is composed of a momentary push button switch, and applies a control voltage to both ends, and one end on the high potential side is connected to one of the input ports of the control unit 10. In other words, the input port of the control unit 10 becomes a high level (control voltage) when the operation unit 11 is not operated, and becomes a low level when the operation unit 11 is operated. Therefore, the control unit 10 receives the operation signal from the operation unit 11 by the input 埠 being at a low level.
顯示部17,例如具有發光顏色為紅色的發紅光二極體(紅光LED)、及發光顏色為綠色的發綠光二極體(綠光LED)。紅光LED,其陰極與控制部10之輸出埠的1個相連接,對陽極施加控制電壓。此外,綠光LED,其陰極與控制部10之輸出埠的另1個相連接,對陽極施加控制電壓。亦即,藉由控制部10,而使顯示部17的紅光LED與綠光LED各別地開啟/關閉(點燈/熄燈)。The display unit 17 has, for example, a red-emitting diode (red LED) having a red-emitting color and a green-emitting diode (green LED) having a green color. The red LED has a cathode connected to one of the output ports of the control unit 10, and a control voltage is applied to the anode. Further, the green LED has its cathode connected to the other output 埠 of the control unit 10, and a control voltage is applied to the anode. That is, the red LED and the green LED of the display unit 17 are individually turned on/off (lighting/turning off) by the control unit 10.
供電部12,係以極性切換部13與觸發部14構成。極性切換部13,如圖2所示,以H橋驅動IC(例如,ROHM社製之BD6231等)構成。此一H橋驅動IC,具有由4個場效電晶體構成的H橋電路130、以及控制H橋電路130的控制器131。對H橋電路130,輸入電源部15的輸出電壓(24伏特的直流電壓)。H橋電路130(極性切換部13)之2個輸出端子132、133中,一方的輸出端子(第1輸出端子)132與遙控繼電器2的繼電器線圈21側之第1訊號端子251相連接,另一方的輸出端子(第2輸出端子)133與觸發部14相連接。控制器131,構成為因應自控制部10之2個輸出埠(第1輸出埠135、第2輸出埠136)輸出的控制訊號,而驅動H橋電路130。亦即,控制器131,在自控制部10的第1輸出埠135輸出控制訊號之情況,以使與觸發部14連接之第2輸出端子133成為高電位的極性(方向),施加電源部15的輸出電壓而驅動H橋電路130。此外,控制器131,在自控制部10的第2輸出埠136輸出控制訊號之情況,以使與遙控繼電器2連接之第1輸出端子132成為高電位的極性(方向),施加電源部15的輸出電壓而驅動H橋電路130。極性切換部13,構成為依據自電源部15供給的恆定電壓,而切換第1信號端子 251與第2信號端子252間的電壓之極性。The power supply unit 12 is configured by a polarity switching unit 13 and a trigger unit 14. As shown in FIG. 2, the polarity switching unit 13 is configured by an H-bridge drive IC (for example, BD6231 manufactured by ROHM Corporation). This H-bridge driver IC has an H-bridge circuit 130 composed of four field effect transistors and a controller 131 that controls the H-bridge circuit 130. The output voltage of the power supply unit 15 (a DC voltage of 24 volts) is input to the H-bridge circuit 130. Of the two output terminals 132 and 133 of the H-bridge circuit 130 (polarity switching unit 13), one output terminal (first output terminal) 132 is connected to the first signal terminal 251 on the relay coil 21 side of the remote control relay 2, and One of the output terminals (second output terminals) 133 is connected to the trigger unit 14. The controller 131 is configured to drive the H-bridge circuit 130 in response to a control signal output from the two output ports (the first output port 135 and the second output port 136) of the control unit 10. In other words, the controller 131 outputs a control signal from the first output port 135 of the control unit 10 so that the second output terminal 133 connected to the trigger unit 14 has a high potential (direction), and the power supply unit 15 is applied. The output voltage drives the H-bridge circuit 130. Further, the controller 131 outputs a control signal from the second output port 136 of the control unit 10 so that the first output terminal 132 connected to the remote control relay 2 has a high potential (direction), and the power supply unit 15 is applied. The H bridge circuit 130 is driven by the output voltage. The polarity switching unit 13 is configured to switch the polarity of the voltage between the first signal terminal 251 and the second signal terminal 252 in accordance with the constant voltage supplied from the power supply unit 15.
觸發部14,如圖2所示,係以複數個(圖示例為3個)光雙向整流耦合器14A、14B、14C構成。光雙向整流耦合器14A、14B、14C,具有發光元件(LED)140、及光雙向整流器141。對發光元件140的正極(陽極)施加控制電壓(DC5V),發光元件140的負極(陰極)分別與控制部10之3個不同的輸出埠各別連接。亦即,各光雙向整流耦合器14A、14B、14C,若控制部10之各輸出埠成為低位準,則發光元件140發光,觸發光雙向整流器141而使其為ON。光雙向整流器141一旦成為導通狀態,則只要電流流通於光雙向整流器141,而無論控制部10之輸出埠的位準高低皆維持光雙向整流器141之導通狀態。在光雙向整流器141為ON時,能夠以藉由極性切換部13切換的極性(方向),自電源部15對遙控繼電器2供給激磁電流。As shown in FIG. 2, the trigger unit 14 is composed of a plurality of (three in the illustrated example) optical bidirectional rectifying couplers 14A, 14B, and 14C. The optical bidirectional rectifying couplers 14A, 14B, and 14C have a light emitting element (LED) 140 and an optical bidirectional rectifier 141. A control voltage (DC5V) is applied to the positive electrode (anode) of the light-emitting element 140, and the negative electrode (cathode) of the light-emitting element 140 is connected to each of three different output ports of the control unit 10. That is, each of the optical bidirectional rectifying couplers 14A, 14B, and 14C causes the light emitting element 140 to emit light when the output turns of the control unit 10 are at a low level, and triggers the optical bidirectional rectifier 141 to turn ON. When the optical bidirectional rectifier 141 is turned on, the current flows through the optical bidirectional rectifier 141, and the conduction state of the optical bidirectional rectifier 141 is maintained regardless of the level of the output 埠 of the control unit 10. When the optical bidirectional rectifier 141 is turned on, the excitation current can be supplied from the power supply unit 15 to the remote control relay 2 with the polarity (direction) switched by the polarity switching unit 13.

A rectangular window opening is opened in the center of the mounting frame 200, and the body 100 of the switch device 1 is embedded in the window. In the side walls located on the left and right sides of the window hole, three sets of the fitting holes 201 of one set are provided in each of the three groups along the longitudinal direction. In addition, mounting pieces 202 are respectively disposed on the upper and lower sides of the window opening.

此處,使全部的開關5為ON,並使全部的遙控繼電器2為OFF。因此,此一狀態下,全部的照明負載4熄燈。此外,開關裝置1中,控制部10,藉由僅將綠光LED點燈,而於顯示部17顯示全部的照明負載4熄燈之情形。Here, all the switches 5 are turned on, and all of the remote control relays 2 are turned off. Therefore, in this state, all of the illumination load 4 is turned off. Further, in the switch device 1, the control unit 10 displays the case where all the illumination loads 4 are turned off on the display unit 17 by lighting only the green LEDs.
若在上述狀態下將操作手柄110進行按壓操作,則控制部10,自操作部11接收操作訊號。收到操作訊號的控制部10,控制極性切換部13而切換為使第1輸出端子132為正極並使第2輸出端子133為負極的極性(t=t0)。接著,控制部10,藉由使光雙向整流耦合器14A之輸入端子為低位準,而對遙控繼電器2A之訊號端子間,施加使繼電器線圈21側為正的訊號電壓(24伏特的直流電壓)。亦即,控制部10,將輸入光雙向整流耦合器14A的電壓(參考圖5C)自高位準切換為低位準。藉此,使光雙向整流耦合器14A之光雙向整流器141成為ON。此一結果,以使第1訊號端子251成為高電位(參考圖5F)的方式,對遙控繼電器2A之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t1)。When the operation handle 110 is pressed in the above state, the control unit 10 receives an operation signal from the operation unit 11. The control unit 10 that has received the operation signal controls the polarity switching unit 13 to switch the polarity of the first output terminal 132 to the positive electrode and the second output terminal 133 to the negative electrode (t=t0). Next, the control unit 10 applies a signal voltage (24 volt DC voltage) to the relay coil 21 side between the signal terminals of the remote control relay 2A by setting the input terminal of the optical bidirectional rectifying coupler 14A to a low level. . That is, the control unit 10 switches the voltage (refer to FIG. 5C) of the input optical bidirectional rectifying coupler 14A from a high level to a low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14A is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2A so that the first signal terminal 251 is at a high potential (refer to FIG. 5F). (t=t1).
遙控繼電器2A中,藉由施加該訊號電壓而使激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為ON而切換至二極體24側。若使遙控繼電器2A(之主接點20)為ON,則自交流電源3通過遙控繼電器2A對照明負載4A供給交流電力,將照明負載4A點燈。另,一旦將遙控繼電器2A之輔助接點22(即輔助接點22之共通端子)切換至二極體24側,則激磁電流變得無法流通,故光雙向整流耦合器14A之光雙向整流器141關閉。如此,光雙向整流耦合器14A之光雙向整流器141,與遙控繼電器2A之輔助接點22連動,結果,與遙控繼電器2A之主接點20連動。亦即,控制部10,對遙控繼電器2A,施加脈波狀的訊號電壓(參考圖5F)(t=t1’)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2A自開路狀態切換為閉路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2A, the excitation current flows through the relay coil 21 by applying the signal voltage, so the auxiliary contact 22 (i.e., the common terminal of the auxiliary contact 22) is switched to the second pole as the main contact 20 is turned ON. Body 24 side. When the remote control relay 2A (the main contact 20) is turned on, the AC power is supplied from the AC power supply 3 to the illumination load 4A via the remote control relay 2A, and the illumination load 4A is turned on. Further, when the auxiliary contact 22 of the remote control relay 2A (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 24, the exciting current becomes impossible to flow, so the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14A shut down. Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14A is interlocked with the auxiliary contact 22 of the remote control relay 2A, and as a result, it is interlocked with the main contact 20 of the remote control relay 2A. That is, the control unit 10 applies a pulse-like signal voltage to the remote control relay 2A (refer to Fig. 5F) (t = t1'). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2A is switched from the open state to the closed state.
使遙控繼電器2A為ON後,控制部10,藉由使光雙向整流耦合器14B之輸入端子為低位準,而對遙控繼電器2B之訊號端子間,施加使繼電器線圈21側為正的訊號電壓(24伏特的直流電壓)。亦即在使遙控繼電器2A為ON後,控制部10,將輸入光雙向整流耦合器14B的電壓(參考圖5D)自高位準切換為低位準。藉此,使光雙向整流耦合器14B之光雙向整流器141成為ON。此一結果,以使第1訊號端子251成為高電位(參考圖5G)的方式,對遙控繼電器2B之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t2)。When the remote control relay 2A is turned on, the control unit 10 applies a signal voltage positive to the relay coil 21 side between the signal terminals of the remote control relay 2B by setting the input terminal of the optical bidirectional rectifying coupler 14B to a low level ( 24 volt DC voltage). That is, after the remote control relay 2A is turned ON, the control unit 10 switches the voltage of the input optical bidirectional rectifying coupler 14B (refer to FIG. 5D) from the high level to the low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14B is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2B so that the first signal terminal 251 is at a high potential (refer to FIG. 5G). (t=t2).
遙控繼電器2B中,藉由施加該訊號電壓而使激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為ON而切換至二極體24側。若使遙控繼電器2B(之主接點20)為ON,則自交流電源3通過遙控繼電器2B對照明負載4B供給交流電力,將照明負載4B點燈。另,一旦將遙控繼電器2B之輔助接點22(即輔助接點22之共通端子)切換至二極體24側,則激磁電流變得無法流通,故光雙向整流耦合器14B之光雙向整流器141關閉。如此,光雙向整流耦合器14B之光雙向整流器141,與遙控繼電器2B之輔助接點22連動,結果,與遙控繼電器2B之主接點20連動。亦即,控制部10,與遙控繼電器2A同樣地,亦對遙控繼電器2B施加脈波狀的訊號電壓(參考圖5G)(t=t2’)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2B自開路狀態切換為閉路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2B, the excitation current flows through the relay coil 21 by applying the signal voltage, so the auxiliary contact 22 (that is, the common terminal of the auxiliary contact 22) is switched to the second pole as the main contact 20 is turned ON. Body 24 side. When the remote control relay 2B (the main contact 20) is turned on, the AC power is supplied from the AC power supply 3 to the illumination load 4B via the remote control relay 2B, and the illumination load 4B is turned on. When the auxiliary contact 22 of the remote control relay 2B (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 24, the exciting current becomes impossible to flow, so the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14B. shut down. Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14B is interlocked with the auxiliary contact 22 of the remote control relay 2B, and as a result, is interlocked with the main contact 20 of the remote control relay 2B. In other words, the control unit 10 applies a pulse-like signal voltage (see Fig. 5G) to the remote control relay 2B in the same manner as the remote control relay 2A (t = t2'). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2B is switched from the open state to the closed state.
使遙控繼電器2B為ON後,控制部10,藉由使光雙向整流耦合器14C之輸入端子為低位準,而對遙控繼電器2C之訊號端子間,施加使繼電器線圈21側為正的訊號電壓(24伏特的直流電壓)。亦即,使遙控繼電器2B為ON後,控制部10,將輸入光雙向整流耦合器14C的電壓(參考圖5E)自高位準切換為低位準。藉此,使光雙向整流耦合器14C之光雙向整流器141成為ON。此一結果,以使第1訊號端子251成為高電位(參考圖5H)的方式,對遙控繼電器2C之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t3)。When the remote control relay 2B is turned on, the control unit 10 applies a signal voltage to the relay terminal 21 side to the signal terminal of the remote control relay 2C by setting the input terminal of the optical bidirectional rectifying coupler 14C to a low level ( 24 volt DC voltage). That is, after the remote control relay 2B is turned on, the control unit 10 switches the voltage (refer to FIG. 5E) of the input optical bidirectional rectifying coupler 14C from a high level to a low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14C is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2C so that the first signal terminal 251 is at a high potential (refer to FIG. 5H). (t=t3).
遙控繼電器2C中,藉由施加該訊號電壓而使激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為ON而切換至二極體24側。若使遙控繼電器2C(之主接點20)為ON,則自交流電源3通過遙控繼電器2C對照明負載4C供給交流電力,將照明負載4C點燈。另,一旦遙控繼電器2C之輔助接點22(即輔助接點22之共通端子)切換至二極體24側,則激磁電流變得無法流通,故光雙向整流耦合器14C之光雙向整流器141關閉。如此,光雙向整流耦合器14C之光雙向整流器141,與遙控繼電器2C之輔助接點22連動,結果,與遙控繼電器2C之主接點20連動。亦即,控制部10,與遙控繼電器2A、2B同樣地,亦對遙控繼電器2C施加脈波狀的訊號電壓(參考圖5H)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2C自開路狀態切換為閉路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2C, the excitation current flows through the relay coil 21 by applying the signal voltage, so the auxiliary contact 22 (i.e., the common terminal of the auxiliary contact 22) is switched to the second pole as the main contact 20 is turned ON. Body 24 side. When the remote control relay 2C (the main contact 20) is turned on, the AC power is supplied from the AC power supply 3 to the illumination load 4C via the remote control relay 2C, and the illumination load 4C is turned on. Further, when the auxiliary contact 22 of the remote control relay 2C (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 24, the exciting current becomes impossible to flow, so the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14C is turned off. . Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14C is interlocked with the auxiliary contact 22 of the remote control relay 2C, and as a result, is interlocked with the main contact 20 of the remote control relay 2C. In other words, similarly to the remote control relays 2A and 2B, the control unit 10 applies a pulse-shaped signal voltage to the remote control relay 2C (refer to FIG. 5H). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2C is switched from the open state to the closed state.
進一步,控制部10,在使全部的遙控繼電器2為ON後,控制極性切換部13以使第1輸出端子132及第2輸出端子133為同電位(t=t4)。另,控制部10,藉由僅將紅光LED點燈,而於顯示部17顯示全部的照明負載4點燈之情形。Further, after turning on all of the remote control relays 2, the control unit 10 controls the polarity switching unit 13 so that the first output terminal 132 and the second output terminal 133 have the same potential (t=t4). Further, the control unit 10 displays the case where all the illumination loads 4 are turned on on the display unit 17 by lighting only the red LEDs.
若在全部的照明負載4點燈之狀態下將操作手柄110進行按壓操作,則控制部10,自操作部11接收操作訊號。收到操作訊號的控制部10,控制極性切換部13而切換為使第2輸出端子133為正極並使第1輸出端子132為負極的極性(t=t5)。接著,控制部10,藉由使光雙向整流耦合器14A之輸入端子為低位準,而對遙控繼電器2A之訊號端子間,施加使繼電器線圈21側為負的訊號電壓(24伏特的直流電壓)。亦即,控制部10,將輸入光雙向整流耦合器14A的電壓(參考圖5C)自高位準切換為低位準。藉此,使光雙向整流耦合器14A之光雙向整流器141成為ON。此一結果,以使第2訊號端子252成為高電位(參考圖5F)的方式,對遙控繼電器2A之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t6)。When the operation handle 110 is pressed in a state where all of the illumination loads 4 are turned on, the control unit 10 receives an operation signal from the operation unit 11. The control unit 10 that has received the operation signal controls the polarity switching unit 13 to switch the polarity of the second output terminal 133 to the positive electrode and the first output terminal 132 to the negative electrode (t=t5). Next, the control unit 10 applies a signal voltage (24 volt DC voltage) to the relay coil 21 side between the signal terminals of the remote control relay 2A by setting the input terminal of the optical bidirectional rectifying coupler 14A to a low level. . That is, the control unit 10 switches the voltage (refer to FIG. 5C) of the input optical bidirectional rectifying coupler 14A from a high level to a low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14A is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2A so that the second signal terminal 252 is at a high potential (refer to FIG. 5F). (t=t6).
遙控繼電器2A中,藉由施加該訊號電壓而使反方向的激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為OFF而切換至二極體23側。若使遙控繼電器2A(之主接點20)為OFF,則成為未自交流電源3對照明負載4A供給交流電力而將照明負載4A熄燈。另,一旦將遙控繼電器2A之輔助接點22(即輔助接點22之共通端子)切換至二極體23側,則反方向的激磁電流變得無法流通,故光雙向整流耦合器14A之光雙向整流器141關閉。如此,光雙向整流耦合器14A之光雙向整流器141,與遙控繼電器2A之輔助接點22連動,結果,與遙控繼電器2A之主接點20連動。亦即,控制部10,對遙控繼電器2A,施加脈波狀的訊號電壓(參考圖5F)(t=t6’)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2A自閉路狀態切換為開路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2A, by applying the signal voltage, the exciting current in the opposite direction flows through the relay coil 21, so the auxiliary contact 22 (that is, the common terminal of the auxiliary contact 22) is switched as the main contact 20 is turned OFF. To the side of the diode 23 . When the remote control relay 2A (the main contact 20) is turned off, the AC power is not supplied from the AC power source 3 to the illumination load 4A, and the illumination load 4A is turned off. When the auxiliary contact 22 of the remote control relay 2A (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 23, the exciting current in the opposite direction becomes impossible to flow, so the light of the optical bidirectional rectifying coupler 14A The bidirectional rectifier 141 is turned off. Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14A is interlocked with the auxiliary contact 22 of the remote control relay 2A, and as a result, it is interlocked with the main contact 20 of the remote control relay 2A. That is, the control unit 10 applies a pulse-like signal voltage to the remote control relay 2A (refer to Fig. 5F) (t = t6'). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2A is switched from the closed state to the open state.
使遙控繼電器2A為OFF後,控制部10,藉由使光雙向整流耦合器14B之輸入端子為低位準,而對遙控繼電器2B之訊號端子間,施加使繼電器線圈21側為負的訊號電壓(24伏特的直流電壓)。亦即,使遙控繼電器2A為OFF後,控制部10,將輸入光雙向整流耦合器14B的電壓(參考圖5D)自高位準切換為低位準。藉此,使光雙向整流耦合器14B之光雙向整流器141成為ON。此一結果,以使第2訊號端子252成為高電位(參考圖5G)的方式,對遙控繼電器2B之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t7)。When the remote control relay 2A is turned off, the control unit 10 applies a signal voltage that causes the relay coil 21 side to be negative between the signal terminals of the remote control relay 2B by setting the input terminal of the optical bidirectional rectifying coupler 14B to a low level ( 24 volt DC voltage). That is, after the remote control relay 2A is turned off, the control unit 10 switches the voltage of the input optical bidirectional rectifying coupler 14B (refer to FIG. 5D) from the high level to the low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14B is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2B so that the second signal terminal 252 is at a high potential (refer to FIG. 5G). (t=t7).
遙控繼電器2B中,藉由施加該訊號電壓而使反方向的激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為OFF而切換至二極體23側。若使遙控繼電器2B(之主接點20)為OFF,則成為未自交流電源3對照明負載4B供給交流電力而將照明負載4B熄燈。另,一旦遙控繼電器2B之輔助接點22(即輔助接點22之共通端子)切換至二極體23側,則反方向的激磁電流變得無法流通,故光雙向整流耦合器14B之光雙向整流器141關閉。如此,光雙向整流耦合器14B之光雙向整流器141,與遙控繼電器2B之輔助接點22連動,結果,與遙控繼電器2B之主接點20連動。亦即,控制部10,與遙控繼電器2A同樣地,亦對遙控繼電器2B施加脈波狀的訊號電壓(參考圖5G)(t=t7’)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2B自閉路狀態切換為開路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2B, by applying the signal voltage, the exciting current in the opposite direction flows through the relay coil 21, so the auxiliary contact 22 (i.e., the common terminal of the auxiliary contact 22) is switched as the main contact 20 is turned OFF. To the side of the diode 23 . When the remote control relay 2B (the main contact 20) is turned off, the AC power is not supplied from the AC power source 3 to the illumination load 4B, and the illumination load 4B is turned off. Further, when the auxiliary contact 22 of the remote control relay 2B (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 23, the exciting current in the opposite direction becomes incapable of flowing, so that the optical bidirectional rectifying coupler 14B is bidirectional in light. The rectifier 141 is turned off. Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14B is interlocked with the auxiliary contact 22 of the remote control relay 2B, and as a result, is interlocked with the main contact 20 of the remote control relay 2B. In other words, the control unit 10 applies a pulse-like signal voltage (see Fig. 5G) to the remote control relay 2B in the same manner as the remote control relay 2A (t = t7'). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2B is switched from the closed state to the open state.
使遙控繼電器2B為OFF後,控制部10,藉由使光雙向整流耦合器14C之輸入端子為低位準,而對遙控繼電器2C之訊號端子間,施加使繼電器線圈21側為負的訊號電壓(24伏特的直流電壓)。亦即,控制部10,將輸入光雙向整流耦合器14C的電壓(參考圖5E)自高位準切換為低位準。藉此,使光雙向整流耦合器14C之光雙向整流器141成為ON。此一結果,以使第2訊號端子252成為高電位(參考圖5H)的方式,對遙控繼電器2C之第1訊號端子251與第2訊號端子252之間施加訊號電壓(24伏特的直流電壓)(t=t8)。When the remote control relay 2B is turned off, the control unit 10 applies a signal voltage that causes the relay coil 21 side to be negative between the signal terminals of the remote control relay 2C by setting the input terminal of the optical bidirectional rectifying coupler 14C to a low level ( 24 volt DC voltage). That is, the control unit 10 switches the voltage of the input optical bidirectional rectifying coupler 14C (refer to FIG. 5E) from a high level to a low level. Thereby, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14C is turned ON. As a result, a signal voltage (24 volt DC voltage) is applied between the first signal terminal 251 and the second signal terminal 252 of the remote control relay 2C so that the second signal terminal 252 is at a high potential (refer to FIG. 5H). (t=t8).
遙控繼電器2C中,藉由施加該訊號電壓而使反方向的激磁電流流通於繼電器線圈21,故輔助接點22(即輔助接點22之共通端子)隨著使主接點20為OFF而切換至二極體23側。若使遙控繼電器2C(之主接點20)為OFF,則成為未自交流電源3對照明負載4C供給交流電力而將照明負載4C熄燈。另,一旦遙控繼電器2C之輔助接點22(即輔助接點22之共通端子)切換至二極體23側,則反方向的激磁電流變得無法流通,故光雙向整流耦合器14C之光雙向整流器141關閉。如此,光雙向整流耦合器14C之光雙向整流器141,與遙控繼電器2C之輔助接點22連動,結果,與遙控繼電器2C之主接點20連動。亦即,控制部10,與遙控繼電器2A、2B同樣地,亦對遙控繼電器2C施加脈波狀的訊號電壓(參考圖5H)。因此,控制部10,控制供電部12,以相較於將遙控繼電器2C自閉路狀態切換為開路狀態的時間並未更短暫的短時間供給電力。In the remote control relay 2C, by applying the signal voltage, the exciting current in the opposite direction flows through the relay coil 21, so the auxiliary contact 22 (that is, the common terminal of the auxiliary contact 22) is switched as the main contact 20 is turned OFF. To the side of the diode 23 . When the remote control relay 2C (the main contact 20) is turned off, the AC power is not supplied from the AC power source 3 to the illumination load 4C, and the illumination load 4C is turned off. Further, when the auxiliary contact 22 of the remote control relay 2C (i.e., the common terminal of the auxiliary contact 22) is switched to the side of the diode 23, the exciting current in the opposite direction becomes impossible to flow, so that the optical bidirectional rectifying coupler 14C is bidirectional in light. The rectifier 141 is turned off. Thus, the optical bidirectional rectifier 141 of the optical bidirectional rectifying coupler 14C is interlocked with the auxiliary contact 22 of the remote control relay 2C, and as a result, is interlocked with the main contact 20 of the remote control relay 2C. In other words, similarly to the remote control relays 2A and 2B, the control unit 10 applies a pulse-shaped signal voltage to the remote control relay 2C (refer to FIG. 5H). Therefore, the control unit 10 controls the power supply unit 12 to supply electric power in a shorter period of time than when the remote control relay 2C is switched from the closed state to the open state.
進一步,控制部10,在使全部的遙控繼電器2為OFF後,控制極性切換部13以使第1輸出端子132及第2輸出端子133為同電位(t=t9)。另,控制部10,藉由僅將綠光LED點燈,而於顯示部17顯示全部的照明負載4熄燈之情形。Further, after turning off all of the remote control relays 2, the control unit 10 controls the polarity switching unit 13 so that the first output terminal 132 and the second output terminal 133 have the same potential (t=t9). Further, the control unit 10 displays on the display unit 17 that all of the illumination loads 4 are turned off by lighting only the green LEDs.
此處,各遙控繼電器2A、2B、2C之一方的訊號端子(與繼電器線圈21連接的訊號端子)與,開關裝置1之共通端子(極性切換部13之第1輸出端子132)相連接。此外,各遙控繼電器2A、2B、2C之另一方的訊號端子(與二極體23、24連接的訊號端子),分別與觸發部14之各光雙向整流耦合器14A、14B、14C的輸出端子相連接。Here, the signal terminal (the signal terminal connected to the relay coil 21) of one of the remote control relays 2A, 2B, and 2C is connected to the common terminal (the first output terminal 132 of the polarity switching portion 13) of the switching device 1. Further, the other signal terminals (signal terminals connected to the diodes 23 and 24) of the remote control relays 2A, 2B, and 2C are respectively output terminals of the optical bidirectional rectifying couplers 14A, 14B, and 14C of the trigger unit 14 Connected.
然而,因配線施工時的操作錯誤,而有例如開關裝置1之共通端子與觸發部14中的任一光雙向整流耦合器14A、14B、14C之輸出端子誤結線的可能。如此地開關裝置1在誤結線的狀態下動作之情況,過大的電流流通於觸發部14及極性切換部13,而有開關裝置1故障的可能。亦即,連接在開關裝置1的共通端子與觸發部14中之任一光雙向整流耦合器14A、14B、14C的輸出端子之間的電路之電阻值,較構成遙控繼電器2的電氣零件之電阻值更低,故過大的電流流通於供電部12。However, there is a possibility that the output terminals of the switching device 1 and the output terminals of any of the optical bidirectional rectifying couplers 14A, 14B, and 14C are misinterpreted due to an operation error during wiring construction. When the switching device 1 operates in the state of the misconnection line, an excessive current flows through the trigger unit 14 and the polarity switching unit 13, and the switching device 1 may malfunction. That is, the resistance value of the circuit connected between the common terminal of the switching device 1 and the output terminal of any of the optical bidirectional rectifying couplers 14A, 14B, 14C of the triggering portion 14 is more than the resistance value of the electrical component constituting the remote control relay 2. Since it is low, an excessive current flows in the power supply unit 12.
相對於此,本實施形態之開關裝置1中的供電部12構成為,若輸出電流超過上限值,則停止輸出電流的供給。亦即,構成極性切換部13之H橋驅動IC,以對於接地電流、短路電流等異常電流之IC保護為目的,而內建過電流保護電路134(參考圖2)。而在自第1輸出端子132及第2輸出端子133輸出的電流超過上限值之情況,自過電流保護電路134對控制器131輸出停止訊號。控制器131,若收到該停止訊號,則使H橋電路130之全部的場效電晶體為OFF而停止輸出電流的供給。此一結果,過大的電流未繼續流通於開關裝置1,故可抑制因配線錯誤等而造成之開關裝置1的故障發生。另,亦可取代內建於H橋驅動IC之過電流保護電路134,而使供電部12具備過電流保護電路,在輸出電流超過上限值時停止輸出電流的供給。On the other hand, in the switching device 1 of the present embodiment, the power supply unit 12 is configured to stop the supply of the output current when the output current exceeds the upper limit value. In other words, the H-bridge drive IC constituting the polarity switching unit 13 has an overcurrent protection circuit 134 (see FIG. 2) for the purpose of IC protection for abnormal currents such as a ground current and a short-circuit current. On the other hand, when the current output from the first output terminal 132 and the second output terminal 133 exceeds the upper limit value, the overcurrent protection circuit 134 outputs a stop signal to the controller 131. When receiving the stop signal, the controller 131 turns off all of the field effect transistors of the H-bridge circuit 130 to stop the supply of the output current. As a result, an excessive current does not continue to flow through the switching device 1, and it is possible to suppress the occurrence of a failure of the switching device 1 due to a wiring error or the like. Further, instead of the overcurrent protection circuit 134 built in the H-bridge driver IC, the power supply unit 12 may be provided with an overcurrent protection circuit to stop the supply of the output current when the output current exceeds the upper limit value.
