본 고안은 전기회로를 접속 또는 개방시키는 전력개폐기에 있어서, 전력개폐기의 접속 또는 개방시에 발생되는 가동접촉단자 및 고정접촉단자의 접점사고를 경감시킬 수 있게 한 투입저항장치의 개량에 관한 것이다.The present invention relates to an improvement of an input resistance device that can reduce contact accidents of a movable contact terminal and a fixed contact terminal generated when a power switch is connected or opened in an electric switch.
전력개폐기는 그의 접속시에 과도 초기 들입전류가 흐르게 되고, 개방시에 스파아크가 발생되어 접점이 손상되는 결점이 있었다.The power switch has the drawback that a transient initial input current flows at the time of its connection, and sparks occur at the time of opening, thereby damaging the contact.
따라서, 종래에는 상기와 같은 전력개폐기의 접점사고를 경감시키기 위해, 보조 투입저항용 접촉단자를 주고정접촉단자와는 별도로 설치하여, 가동접촉단자의 접속시에는 그 가동 접촉단자가 보조 투입저항용 접촉단자에 먼저 접속되어 과도 초기돌입전류의 흐름을 제한시킨 후 주고정접촉단자에 접속되게 하고, 가동접촉단자의 개방시에는 그 가동접촉단자가 주고정접촉단자에서 먼저 개방된 후 보조 투입저항용 접촉단자에서 개방되게 하여 스파아크의 발생을 저하시켰다.Accordingly, in order to alleviate the above-mentioned contact accident of the power switch, the auxiliary input resistance contact terminal is provided separately from the static contact terminal, and when the movable contact terminal is connected, the movable contact terminal is used for the auxiliary input resistance. It is first connected to the contact terminal to limit the flow of excessive initial inrush current, and then connected to the sub positive contact terminal.When the movable contact terminal is opened, the movable contact terminal is first opened at the sub positive contact terminal and then used for auxiliary input resistance. Opening at the contact terminals reduced the generation of sparks.
그러나, 이러한 종래의 장치에 있어서는 보조 투입저항용 접촉단자를 주고정접촉단자와는 별도로 설치하므로 그의 구조가 복잡하게 되어 소형화 할 수 없게되고, 개폐기의 종류 및 형태의 대소에 따라 적용하기 어려웠으며, 또한 가동접촉단자가 주고정접촉단자 및 보조 투입저항용 접촉단자에 접속 또는 개방되는 순서 기능이 불확실하게 되는 결점이 있었다.However, in such a conventional apparatus, since the auxiliary input resistance contact terminal is provided separately from the positive contact terminal, its structure becomes complicated and cannot be miniaturized, and it is difficult to apply it depending on the type and shape of the switch. In addition, there is a drawback that the sequence function in which the movable contact terminal is connected or opened to the sub-static contact terminal and the auxiliary input resistance contact terminal is uncertain.
본 고안은 이러한 점을 감안하여, 주고정접촉단자에 통공을 형성한 후 그 주고정접촉단자의 통공내로 보조 투입저항용 접촉단자가 유동되게 탄력설치하여, 가동접촉단자가 주고정접촉단자 및 보조 투입저항용 접촉단자에 접속 또는 개방되는 순서기능을 절대적으로 보장하고, 공간점유가 적게되어 각종 개폐기에 적용할 수 있게 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of this point, the present invention forms a through hole in the sub fixed contact terminal, and then elastically installs the contact terminal for auxiliary input resistance to flow into the through hole of the sub fixed contact terminal. Absolutely guarantees the order function to be connected or opened to the contact resistance for the input resistance, the space occupancy is reduced to be applied to various switchgear, which will be described in detail by the accompanying drawings as follows.
제1도 및 제2도에 도시한 바와같이, 가동접촉단자(1a)의 접속시에는 주고정접촉단자(2)보다 먼저 접속되고 개방시에는 주고정접촉단자(2)보다 늦게 개방되는 전력개폐기의 투입저항장치에 있어서, 주고정편(3)에 형성된 주고정접촉단자(2)의 중앙을 뚫어 관통공(2a)을 형성한 후 그 관통공(2a)의 주연 및 주고정접촉단자(2)의 하단에 절연피막(4)을 형성하고, 저항체(6)를 통해 주고정편(3)에 공통 연결된 보조고정편(7)에 관통공(7a)을 형성하여, 그 보조고정편(7)의 관통공(7a)과 상기 주고정접촉단자(2)의 관통공(2a) 사이를 중간부에 단턱(5a)이 형성된 투입저항용 접촉단자(5)가 일정거리 상하이동하게 코일스프링(8)으로 탄력설치하여 구성한 것으로, 도면의 설명중 미설명 부호 1은 가동편, 9는 계전기, 9a는 계전기(9)의 전극, 10은 탄성스프링, 11은 유동철편, 12는 절연편이고, 13a,13b는 부하회로에 연결된 전원공급선이다.As shown in FIG. 1 and FIG. 2, the power switch is connected earlier than the high static contact terminal 2 when the movable contact terminal 1a is connected, and opens later than the high static contact terminal 2 when opened. In the resistance input device of the present invention, the through hole (2a) is formed by drilling the center of the fixed contact terminal (2) formed in the main piece (3), and then the peripheral and high contact terminals (2) of the through hole (2a). The insulating film 4 is formed at the lower end of the, and a through hole 7a is formed in the auxiliary fixing piece 7 which is commonly connected to the fixing piece 3 through the resistor 6, and the auxiliary fixing piece 7 is formed. The contact spring (5) for the input resistance having the stepped portion (5a) formed in the middle between the through hole (7a) of the through hole (2a) and the through hole (2a) of the sub-constant contact terminal (2) is a coil spring ( 8), the reference numeral 1 in the description of the drawings, the movable piece, 9 is the relay, 9a is the electrode of the relay 9, 10 is an elastic spring, 11 is a moving iron piece, 12 is Pretty soft, 13a, 13b is a power supply line connected to the load circuit.
이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.
계전기(9)에 전원이 인가되어 그 계전기(9)의 전극(9a)에 자력이 발생되면, 그 자력에 의해 유동철편(11)이 하강되면서 가동편(1)을 하강시키므로 가동편(1)의 가동접촉단자(1a)는 제2도의 (a)에 도시한 바와 같이 투입저항용 접촉단자(5)에 먼저 접촉된다. 이에따라, 전원공급선(13a)은 가동편(1) 및 그의 가동접촉단자(1a), 투입저항용 접촉단자(5), 보조고정편(7), 저항체(6)를 통해 전원공급선(13b)과 폐회로를 구성하게 되므로 저항체(6)에서 전류의 흐름의 제한되고, 이후 제2도의 (b)에 도시한 바와 같이 가동편(1)이 더 하강되어 그의 가동접촉단자(1a)가 주고정접촉단자(2)에 접촉하게 되면, 이때 비로소 주고정편(3)을 통해 정상적인 전류가 흐르게 되므로, 가동접촉편(1a)의 접속시에 과도초기돌입전류를 확실히 제한하게 된다.When power is applied to the relay 9 and a magnetic force is generated in the electrode 9a of the relay 9, the movable piece 1 is lowered while the moving iron piece 11 is lowered by the magnetic force. Of the movable contact terminal 1a is first brought into contact with the contact resistance 5 for the input resistance, as shown in FIG. Accordingly, the power supply line 13a is connected to the power supply line 13b through the movable piece 1 and its movable contact terminal 1a, the contact resistance 5 for the input resistance, the auxiliary fixing piece 7, and the resistor 6. Since a closed circuit is constituted, current flow in the resistor 6 is restricted, and as shown in (b) of FIG. 2, the movable piece 1 is further lowered so that the movable contact terminal 1a is given to the positive contact terminal. When it comes into contact with (2), since the normal current flows through the sub-piece 3 at this time, the transient initial inrush current at the time of connection of the movable contact piece 1a is surely limited.
그리고, 계전기(9)의 구동이 중지되어 가동편(1)의 가동접촉단자(1a)가 개방될때는 상기와는 역순으로 가동접촉 단자(1a)가 주고정접촉단자(2)에서 먼저 개방되고, 이때 투입저항용접촉단자(5)는 코일스프링(8)의 탄력에 의해 가동접촉단자(1a)에 접촉된 상태를 유지하게 되며, 이후 가동접촉단자(1a)가 더 상승되어 투입저항용접촉단자(5)의 단턱(5a)이 절연피막(4)에 접촉되어 정지될때 비로소 가동접촉단자(1a)가 투입저항용접촉단자(5)로 부터 개방되므로, 가동접촉단자(1a)의 개방시에 스파아크발생을 거의 없앨수 있게 된다.When the driving of the relay 9 is stopped and the movable contact terminal 1a of the movable piece 1 is opened, the movable contact terminal 1a is first opened in the reverse contact terminal 2 in the reverse order as described above. At this time, the input resistance contact terminal 5 is maintained in contact with the movable contact terminal 1a by the elasticity of the coil spring 8, and then the movable contact terminal 1a is further raised to contact the input resistance. When the step 5a of the terminal 5 comes into contact with the insulating film 4 and is stopped, the movable contact terminal 1a is opened from the contact resistance 5 for the input resistance, so that the movable contact terminal 1a is opened. It is possible to almost eliminate the occurrence of sparks.
이상에서와같이 본 고안은 전력개폐기의 접속시에 가동 접촉단자가 투입저항용접촉단자에 먼저 접촉되지 않고는 주고정접촉단자에 접촉될 수 없고, 전력개폐기의 개방시에 가동 접촉단자가 주고정접촉단자에서 먼저 개방되지 않고서는 투입저항용접촉단자에서 개방될 수 없으므로 전력개폐기의 접촉 또는 개방시에 투입저항 순서기능이 확실히 보장되어 접점사고를 경감시킬 수 있게되고, 또한 투입저항용접촉단자가 주고정접촉단자의 관통공을 통해, 상·하 이동하는 간단한 구조이므로 소형화할 수 있고, 각종 전력개폐기에 쉽게 적용시켜 사용할 수 있는 이점이 있게 된다.As described above, the present invention can not contact the positive contact terminal unless the movable contact terminal first contacts the contact resistance for the input resistance when the power switch is connected, and the movable contact terminal is fixed when the power switch is opened. Since it cannot be opened at the contact resistance for input resistance without first opening at the contact terminal, the order of the input resistance is ensured at the time of contact or opening of the power switch, thereby reducing contact accidents. Through the through hole of the high positive contact terminal, it can be downsized because it is a simple structure to move up and down, there is an advantage that can be easily applied to various power switch.
