Description

直流控制斷路器斷電跳脫系統改良裝置 DC control circuit breaker power off system improvement device

本創作是一種直流控制斷路器斷電跳脫系統改良裝置,特別是改善以往大型配電(變電)站中,一般以電池組供電作為主控制迴路使用之受(配)電變站,當該直流供電系統發生問題,有事故發生時無法隔離事故的疑慮,本創作直流控制斷路器斷電跳脫系統改良裝置,引入電流偵測裝置降流單元的電能作為跳脫系統的備用電源,以驅動跳脫線圈使跳脫機構動作斷開斷路器,可以在以往跳脫迴路電源皆失能情況下,安全斷路跳脫隔離事故,安全可靠可增強其供電品質。 This creation is a modified device for the DC control circuit breaker power-off trip system, especially for improving the large-scale power distribution (substation) station in the past, generally using the battery pack power supply as the main control circuit. The DC power supply system has a problem, and there is a doubt that the accident cannot be isolated when the accident occurs. The improved device of the DC control circuit breaker power-off trip system is introduced, and the power of the current detecting device down-flow unit is introduced as the backup power source of the trip system to drive The tripping coil makes the tripping mechanism actuate to open the circuit breaker, which can safely break the trip isolation accident when the tripping power supply is disabled. The safety and reliability can enhance the power supply quality.

在大型受(配)電站,為了供電系統的穩定性,若是在經費充裕的狀況下,並且在空間允許的狀況下,業主會選擇其受(配)電系統其控制電源採用大型電池組組裝之電池供電設備。一般而言,以電池組組成之供電系統,是比較妥善的供電方式。尤其台灣電力公司(TPC)對於高壓(36KV以上)的供受(配)電站,對於其斷路器的控制電源供電方式以直流供應為主,並且一般皆使用蓄電池組供電,以保護其受(配)電供電系統的穩定性。 In the large-scale (scheduled) power station, in order to ensure the stability of the power supply system, if it is under sufficient funds and in the space permitting conditions, the owner will select the power system to be controlled by the large battery pack. Battery powered device. In general, a power supply system consisting of a battery pack is a relatively safe power supply. In particular, the Taiwan Power Company (TPC) provides high-voltage (36KV or higher) supply and supply (distribution) power stations. The control power supply mode for the circuit breakers is mainly DC supply, and the battery packs are generally used to protect them. The stability of the electrical power supply system.

高壓斷路器(H.V.CB)或特高壓CGIS或GIS,是接受保護電 驛(Relay)的指令,做為是否跳脫高壓斷路器,將事故源隔離。因此該斷路器如果不能如期在某一事業單位(受電方)發生短路事故時立即跳脫,將會造成高壓斷路器(H.V.CB)損壞,而擴及到影響主供電幹線供應電源給其他的事業單位(受電方),造成連鎖性的產業損失。高壓斷路器能否及時跳脫,受控於保護電驛(Relay)是否能即時發出指令。因此,當提供保護電驛的工作電源有問題時,該保護電驛就不會動作;該保護電驛不會動作時,高壓CB在事故發生時也就不會動作,無法隔離事業單位的事故點,造成嚴重的二次事故,甚至影響台電供電饋線跳脫!不可不慎。由於此高危險性的工安事件常因誤判而產生意外,於是供電幹線的業者(台灣電力公司)為防止電驛於短路事故時,因電壓驟降無法動作觸發斷路器跳脫,及因比流器飽和遲緩動作,要求事業單位要按照規定設置保護系統,才會答應供電。主要的規定內容是:採比壓器二次側電源供應時,應輔以電容跳脫裝置(CTD)或輔以電容跳脫裝置再併接不斷電系統(UPS),且供電子式或數位式電驛使用之電容跳脫裝置(CTD),不得接供斷路器或其他設備使用。這是理想,但意外常常來自於理想狀況下,實務上不斷電系統(UPS)一年、兩年後幾乎都會因電池老化而故障。若是使用蓄電池組為主的直流供電系統,其電池一年後可能會失能,但是事業單位卻不會察覺到,通常都是有短路事故時,發現高壓斷路器(H.V.CB)不會跳脫,發現沒有跳脫迴路的直流工作電源無法供應工作電源給保護電驛(Relay),但為時已晚。 High voltage circuit breaker (H.V.CB) or UHV CGIS or GIS, is protected by electricity Re (Relay) instructions, as a jump off the high-voltage circuit breaker, to isolate the source of the accident. Therefore, if the circuit breaker cannot jump off immediately in the event of a short-circuit accident in a certain business unit (power receiving party), the high-voltage circuit breaker (HVCB) will be damaged, and the power supply to the main power supply mains will be extended to other businesses. The unit (power receiving party) causes a chain of industrial losses. Whether the high-voltage circuit breaker can jump in time is controlled by whether the relay can immediately issue an instruction. Therefore, when there is a problem with the working power supply for protecting the power, the protection power will not operate; when the protection power does not operate, the high voltage CB will not operate when the accident occurs, and it is impossible to isolate the accident of the public institution. Point, causing a serious secondary accident, and even affecting the Taipower power supply feeder to jump off! Don't be careless. Because this high-risk industrial safety incident often leads to accidents due to misjudgment, the operator of the mains supply line (Taiwan Electric Power Company) can prevent the electric breaker from jumping out of the circuit breaker due to the sudden voltage drop. The flow is saturated and slow, and the institution is required to set the protection system according to the regulations, and then the power supply is promised. The main provisions are: when the secondary side power supply of the comparator is used, it should be supplemented by a capacitive tripping device (CTD) or a capacitor tripping device and then connected to the uninterruptible power system (UPS), and electronically or The Capacitor Trip Unit (CTD) used in digital power units shall not be used for circuit breakers or other equipment. This is ideal, but accidents often come from ideal conditions. In practice, the UPS will almost always fail due to battery aging after one or two years. If the battery-based DC power supply system is used, the battery may be disabled after one year, but the business unit will not notice that the high-voltage circuit breaker (HVCB) will not trip when there is usually a short-circuit accident. It was found that the DC working power supply without the tripping circuit could not supply the working power to the relay, but it was too late.

有鑑於上述因素,因此其蓄電池組的直流供電電能失能時,在這段期間內若是系統發生事故時(無論是任何事故情況),例如CO、LCO、UV、OV……等,其隔離事故點的斷路器,會因為其供給跳脫迴路的工作電 源(蓄電池組之直流電源)失能而會造成高壓盤於系統故障時,跳脫迴路沒有工作電源,而無法隔離事故點的嚴重情形。 In view of the above factors, when the DC power supply of the battery pack is disabled, during the period of the system, if there is an accident (whether any accident), such as CO, LCO, UV, OV, etc., the isolation accident Point circuit breaker, because it supplies power to the trip circuit The failure of the source (the DC power supply of the battery pack) will cause the high voltage disk to fail in the system. The trip circuit has no working power supply, and it cannot isolate the serious situation of the accident point.

在習有以直流蓄電池組為控制電源的系統,可以有單一直流蓄電池組來提供直流電源或者以兩組直流蓄電池組相互支援的方式來提供直流電源,以做為整體配電系統的直流電源供應。實際的配電盤中,其中保護電驛以及斷路器的跳脫迴路中,其中保護電驛的工作電源一般為AC與DC皆可使用以提供其所需之工作電源。在一般的情況下,會以直流電源為優先考量(AC與DC二者只能選定一種),因為一般而言直流電源比較穩定可靠,因此一般以蓄電池組為主的直流供電系統為客戶最喜愛的選項,在場所及經濟皆允許情況下。 In a system with a DC battery pack as a control power source, a single DC battery pack can be provided to provide DC power or a DC power supply can be provided in a mutual support of two sets of DC battery packs as a DC power supply for the overall power distribution system. In the actual switchboard, in which the power circuit and the trip circuit of the circuit breaker are protected, the working power source for protecting the power is generally AC and DC can be used to provide the required working power. Under normal circumstances, DC power supply is a priority (AC and DC can only be selected), because DC power supply is generally stable and reliable, so the battery-based DC power supply system is generally preferred by customers. The options are available wherever the venue and economy are allowed.

在實際狀態是其蓄電池組器材本身的特性,在一年至兩年間會損耗老化而有失能的疑慮,甚至在整個控制電路間也可能發生一些不可預期的狀況,使得該系統中,當跳脫迴路的工作電源失能時,此時如同在使用交流電源(AC source)做為跳脫控制迴路工作電源一般;為防止事故發生時,因為電壓驟降,若直流電源又失能時,可能產生無法使保護電驛作動而造成事故發生。為防止上述情事發生,開發一種可以提供直流電能的控制迴路失能時可能發生的事故,而直流控制斷路器斷電跳脫系統改良裝置可以解決上述的問題的方法之一種。 In the actual state is the characteristics of its battery pack equipment itself, there will be suspicion of loss of aging and disability in one to two years, and even some unpredictable conditions may occur between the entire control circuit, making the system jump When the working power supply of the off-loop is disabled, it is like using AC power as the power supply for the trip control loop. In order to prevent accidents, if the voltage is dimmed, if the DC power supply is disabled, it may be The occurrence of an accident cannot be caused by the protection of the electric power. In order to prevent the above-mentioned situation from occurring, an accident that may occur when the control circuit capable of providing DC power is disabled is developed, and the improved device of the DC control circuit breaker power-off trip system can solve one of the above problems.

本創作申請人對於高壓配電系統中,其高壓配電盤中的跳脫迴路工作電源改善方式,已經有數個方案提出並申請專利。尤其在電容跳脫裝置CTD的改良方面,從在有載之下可測試,有電錶顯示其電壓值,到盤面式可以有效防止因開啟高壓配電盤而可能引起的工安事故預防,有電 壓比較電路及警報電路的電容跳脫裝置可以解決電容器會因時間而衰減的問題,有時間電路與電壓比較電路的組合,可以每日或設定時間以模擬事故發生時,其跳脫迴路工作電源是否足以推動其負載設備以隔離事故,進一步有自動電源轉換電路的CTD,以防止電容跳脫裝置故障時,外部電源有交流及直流電源的支援,以及可以解決電壓以及電容量和通訊的問題,以及直流控制斷路器跳脫使用直流電容跳脫裝置,以上的解決方案是目前市場的產品。 The author of this author has proposed and patented several schemes for the improvement of the working power of the tripping loop in the high-voltage power distribution system in the high-voltage power distribution system. Especially in the improvement of the CTD of the capacitor tripping device, it can be tested under load, and the meter can display its voltage value. The disk surface type can effectively prevent the accident prevention caused by opening the high-voltage switchboard. The capacitor tripping device of the voltage comparison circuit and the alarm circuit can solve the problem that the capacitor will be attenuated due to time. The combination of the time circuit and the voltage comparison circuit can be used to simulate the occurrence of an accident on a daily or set time. Is it enough to push its load equipment to isolate the accident, and further has the CTD of the automatic power conversion circuit to prevent the external power supply from supporting AC and DC power when the capacitor trip device is faulty, and to solve the problems of voltage and capacity and communication. As well as DC control circuit breaker tripping using DC capacitor tripping device, the above solution is the current market product.

綜上所述,以直流電源或交流電源為主的控制迴路,使用於高壓盤的跳脫迴路工作電能失能時,在現場中所面臨實際的狀況,以往並無法有效的來解決該問題,於是從現場中的狀況實際需求,直流控制斷路器斷電跳脫系統改良裝置可以解決上述的問題,同時提昇其配電系統的安全性及穩定性。 In summary, the control circuit based on DC power or AC power is used in the trip circuit of the high voltage disk. When the power is disabled, the actual situation is faced in the field. In the past, this problem cannot be effectively solved. Therefore, from the actual situation of the situation in the field, the improved device of the DC control circuit breaker power-off trip system can solve the above problems and improve the safety and stability of the power distribution system.

The tripping coil 15 is connected to the tripping mechanism 13 of the circuit breaker 10; the power circuit is provided with a voltage detecting device 12 (such as a voltage comparator), and the voltage detecting device 12 includes a step-down unit for reducing the output voltage. The buck unit is electrically coupled to the protection switch 19 and the control loop power supply 28. A current detecting device 11 (such as a current transformer) is also disposed on the power circuit, and the current detecting device 11 includes a downflow unit for reducing the output current; the downflow unit is electrically connected to the protection device 19 and controls The loop power supply 28, the control loop power supply 28 is automatically alternated with the circuit 20 via the power supply, and the corresponding power is selected to be connected in series to the protection switch 19 to connect the protection switch normally open contact 16.

請參考第2圖針對本創作之原理做進一步之說明。如圖2陰影方框所示為一般電流偵測裝置(比流器)的示意圖,電流偵測裝置11之降流單元電流流經一電流錶,形成一完整迴路。而為進一步引入電流偵測裝置11(如比流器)的電流做為斷路器10跳脫線圈15的電源,本創作於電流偵測裝置11之降流單元並聯一側支路徑。此一側支路徑於電力系統正常時,保護電驛19未動作內部的保護電驛常開接點16開路,而斷路器10之斷路器閉 合輔助接點14為導通狀態,此時並未有電流流經側支路徑。但當電力系統故障,保護電驛19動作該保護電驛常開接點16導通及斷路器閉合輔助接點14亦導通,側支路徑即為構成一完整迴路導通狀態,電流偵測裝置11(如比流器)的降流電元電流即通過側支路徑,因而可做為斷路器10跳脫線圈15驅動所需之電力。 Please refer to Figure 2 for further explanation of the principles of this creation. As shown in the shaded box of FIG. 2, it is a schematic diagram of a general current detecting device (current comparator). The current of the downflow unit of the current detecting device 11 flows through an ammeter to form a complete loop. In order to further introduce the current of the current detecting device 11 (such as the current transformer) as the power supply for the circuit breaker 10 to trip the coil 15, the downstream unit of the current detecting device 11 is connected in parallel with the side branch path. When the power system is normal, the protection circuit 19 does not operate, the internal protection power is normally open, the open circuit 16 is open, and the circuit breaker 10 is closed. The auxiliary contact 14 is in an on state, and no current flows through the side branch path at this time. However, when the power system fails, the protection device 19 operates the protection switch, the normally open contact 16 is turned on, and the circuit breaker is closed. The auxiliary contact 14 is also turned on, and the side branch path constitutes a complete loop conduction state, and the current detecting device 11 ( The downflow cell current, such as the current comparator, passes through the side branch path and thus can be used as the power required to drive the circuit breaker 10 to trip the coil 15.

將前述電流偵測裝置11(如比流器)降流單元側支路徑的技術特徵與習用斷路器跳脫電源的設計結合,請參閱第3圖。第3圖左上方陰影方塊,表示習用直流系統電容跳脫裝置中以電池單元24做為斷路器10跳脫線圈15的跳脫電源,其通常在一般情況下,是足以提供斷路器10跳脫線圈15所需的驅動電源。但當電池單元24因人為疏忽、天災巨變、或過期而失能,將無法驅動該跳脫線圈15以隔離事故,此時將產生巨大危害。如將前述引入電流偵測裝置11(如比流器)的降流單元電流源的技術特徵整合,從第3圖可見,當系統故障(保護電驛常開接點16接點導通),若習用技藝之電池單元24失能時,此時電力迴路的電流仍持續通過斷路器10,因此電流偵測裝置11(如比流器)的降流單元的電流源仍持續有電流流通(參閱第2圖)。而此時電源自動交替電路20因習用技藝之電池單元24失能係切換到電流偵測狀置11的迴路,電流如虛線箭號所示流進斷路器10的跳脫線圈15,以驅動跳脫機構13作動,因而可以切斷斷路器10的閉合主接點以隔離事故點,進一步提昇了斷路器跳脫迴路系統的穩定性,以確保電力系統運作的安全。 The technical characteristics of the current-side branching path of the current detecting device 11 (such as a flow comparator) are combined with the design of the conventional circuit breaker tripping power supply, please refer to FIG. The upper left shaded box in Fig. 3 shows the tripping power supply of the conventional DC system capacitor tripping device with the battery unit 24 as the circuit breaker 10 tripping coil 15, which is generally sufficient to provide the circuit breaker 10 tripping. The drive power required for the coil 15. However, when the battery unit 24 is disabled due to human negligence, natural disaster, or expiration, the trip coil 15 cannot be driven to isolate the accident, which will cause great harm. If the technical characteristics of the current source of the downflow unit introduced into the current detecting device 11 (such as a current transformer) are integrated, it can be seen from FIG. 3 that when the system is faulty (the protective power is normally open, the contact 16 is turned on), When the battery unit 24 of the conventional technology is disabled, the current of the power circuit continues to pass through the circuit breaker 10 at this time, so the current source of the downflow unit of the current detecting device 11 (such as the current comparator) continues to have current circulation (see the 2 picture). At this time, the power automatic altering circuit 20 is switched to the circuit of the current detecting state 11 due to the failure of the battery unit 24 of the conventional technology, and the current flows into the trip coil 15 of the circuit breaker 10 as indicated by the dotted arrow to drive the jump. The disengagement mechanism 13 is actuated, so that the closed main contact of the circuit breaker 10 can be cut off to isolate the accident point, further improving the stability of the circuit breaker tripping loop system to ensure the safety of the power system operation.

依據前述原理,本創作直流控制斷路器斷電跳脫系統改良裝置之較佳實施例如功能方塊圖如第4圖所示,直流控制斷路器斷電跳脫系統改良裝置1具有連接電池單元24的直流輸入端及連接電壓偵測裝置12之降 壓單元的交流輸入端。電池單元24作為斷路器跳脫迴路操作所需的電源。另電壓偵測裝置12之降壓單元連接到交流輸入端,經由一交直流轉換電路184轉換為直流電源,該交流轉換電路184一般為橋式整流濾波,此一轉換後之直流電源可做為電路所需的電源,或與來自電池單元24之電源輸出,同時連接到一直流電源交替電路185,該直流電源交替電路185,當電壓偵測裝置12之降壓單元有電時,優先選用交流轉換電路184的直流電源輸出,藉此對電容儲能電路190充電,利用電容儲存跳脫迴路所需之電能。如電壓偵測裝置12之降壓單元失能,直流電源交替電路185選用電池單元24的電源,對電容儲能電路190充電。直流電源交替電路185,通常可使用2A2B1C之繼電器模組或功能相同之切換模組達成(未圖示)。直流電源交替電路185的輸出電源(即電容儲能電路190的輸出電源)與電池單元24的電源,並同時輸入到直流電源並聯輸出電路191,該直流電源並聯輸出電路191並以電容儲能電路190的電能作為優先之提供跳脫迴路所需之電源。直流電源並聯輸出電路191,通常可使用2A2B1C之繼電器模組或功能相同之切換模組達成(未圖示)。而為便於檢視跳脫迴路電源電路18的狀態,電池單元24、電容儲能電路190、直流電源並聯輸出電路191的輸出,可各自連結到偵測電路及顯示單元,如錶頭、七段顯示器或其他液晶顯示面板(未圖示)。偵測電路設有電壓比較電路,以判斷電壓是否高於一預設值,以進行必要之警示。 According to the foregoing principle, a preferred embodiment of the improved device for the DC-controlled circuit breaker power-off trip system is as shown in FIG. 4, and the DC-controlled circuit breaker power-off trip system improving device 1 has a battery unit 24 connected thereto.

The AC converting circuit 184 is generally a bridge rectifying filter, and the converted DC power supply can be used as The power required by the circuit, or the power output from the battery unit 24, is simultaneously connected to the DC power supply circuit 185. The DC power supply circuit 185 is preferred when the voltage step of the voltage detecting device 12 is powered. The DC power output of the conversion circuit 184, thereby charging the capacitor storage circuit 190, utilizes the capacitance to store the electrical energy required to trip the loop. If the buck unit of the voltage detecting device 12 is disabled, the DC power altering circuit 185 selects the power of the battery unit 24 to charge the capacitor storing circuit 190. The DC power altering circuit 185 can usually be implemented using a 2A2B1C relay module or a switching module having the same function (not shown). The output power of the DC power altering circuit 185 (ie, the output power of the capacitor storage circuit 190) and the power of the battery unit 24 are simultaneously input to the DC power parallel output circuit 191, which is connected in parallel with the output circuit 191 and is a capacitor storage circuit. The 190's power is used as a priority to provide the power required to trip the loop.

In order to facilitate the inspection of the state of the loop power supply circuit 18, the output of the battery unit 24, the capacitor storage circuit 190, and the DC power parallel output circuit 191 can be respectively connected to the detection circuit and the display unit, such as the meter head and the seven-segment display. Or other liquid crystal display panel (not shown).

Similarly, the power automatic alternation circuit 20 can usually be achieved by using a 2A2B1C relay module or a switching module having the same function (not shown).
