Description

전자 접촉기Electronic contactor
본 발명은 전자 접촉기에 관한 것이다.The present invention relates to an electromagnetic contactor.
일반적으로 전자 접촉기는 전자석의 원리로 동작하여, 회로를 개폐한다. 이를 위해, 전자 접촉기는 전원과 부하 사이의 회로 상에 배치된다. 그리고 전자접촉기는 회로를 연결하여, 전원으로부터 부하로 전류 공급을 제공한다. 한편, 전자 접촉기는 회로를 차단하여, 전원으로부터 부하로 전류 공급을 차단한다. 이러한 전자 접촉기는, 고정부와 가동부를 포함한다. 고정부와 가동부가 접촉되면, 회로가 연결되며, 고정부와 가동부가 분리되면, 회로가 차단된다. 이 때 고정부와 가동부가 접촉되면, 고정부와 가동부 사이에 전류가 흐른다. In general, the electromagnetic contactor operates on the principle of an electromagnet to open and close a circuit. For this purpose, the magnetic contactor is arranged on a circuit between the power supply and the load. The magnetic contactor then connects the circuit to provide a current supply from the power supply to the load. On the other hand, the magnetic contactor cuts off the circuit and cuts off the supply of current from the power supply to the load. Such an electromagnetic contactor includes a stationary part and a movable part. When the stationary part and the movable part are in contact, the circuit is connected, and when the stationary part and the movable part are separated, the circuit is cut off. At this time, when the stationary part and the movable part are in contact, current flows between the stationary part and the movable part.
그런데, 상기와 같은 전자 접촉기에 과전류가 인가되는 경우, 고정부와 가동부 사이에 전자 반발력이 발생될 수 있다. 이로 인하여, 고정부와 가동부가 분리될 수 있다. 즉 전자 접촉기에 전류가 인가되고 있음에도 불구하고, 고정부와 가동부의 접촉이 유지되지 않을 수 있다. 이에 따라, 고정부와 가동부 사이에 아크(arc)가 발생될 수 있다.However, when an overcurrent is applied to the electromagnetic contactor as described above, an electron repelling force may be generated between the fixed part and the movable part. As a result, the fixed part and the movable part can be separated. That is, even though a current is applied to the electromagnetic contactor, the contact between the fixed part and the movable part may not be maintained. Accordingly, an arc may be generated between the fixed part and the movable part.
다양한 실시예들에 따르면, 전자 접촉기는 고정부와 가동부의 접촉을 유지시킬 수 있다. 이 때 고정부와 가동부가 전자 반발력에 의해 상호로부터 분리되는 것이 방지될 수 있다. 즉 전자 접촉기에 과전류가 인가되더라도, 고정부와 가동부의 접촉이 유지될 수 있다. 이를 통해, 전자 접촉기에서 아크가 발생되는 것이 방지될 수 있다.According to various embodiments, the electromagnetic contactor may maintain contact with the fixed portion and the movable portion. At this time, the fixed portion and the movable portion can be prevented from being separated from each other by the electron repulsive force. That is, even if an overcurrent is applied to the electromagnetic contactor, contact between the fixed part and the movable part can be maintained. Through this, generation of an arc in the electromagnetic contactor can be prevented.

Thus, the fixing portion and the movable portion can be prevented from being separated from each other by the electron repelling force. In addition, the generation of an arc in the electromagnetic contactor can be prevented.

Through this, the electromagnet portion 460 may contact the movable portion 440 to the fixed portion 430. On the other hand, when the applied current is cut off, the electromagnet portion 460 may separate the movable portion 440 from the fixed portion 430.
다양한 실시예들에 따르면, 전자 접촉기(100)에서, 자성부(250, 450)가 고정부(230, 430)와 가동부(240, 440)의 접촉을 유지시킬 수 있다. 즉 가동부(240, 440)가 고정부(430, 440)에 접촉되면, 고정 단자(231, 233, 431, 433)들 사이에서 가동부(240, 440)에 전류가 흐를 수 있다. 그리고 가동부(240, 440)에서 전류의 방향을 중심으로, 자기장이 형성될 수 있다. 이를 통해, 자성부(250, 450)가 자기장에 의해 자화되어, 자기력을 발생시킬 수 있다. 또한 자성부(250, 450)의 자기력에 의해, 고정부(230, 430)와 가동부(240, 440) 사이에 인력이 발생될 수 있다. 이에 따라, 자성부(250, 450)의 자기력에 기반하여, 고정부(230, 430)와 가동부(240, 440)의 접촉이 유지될 수 있다. 이 때 전자 접촉기(100)에 과전류가 인가되는 경우, 자성부(250, 450)의 자기력은 더 강해지며, 고정부(230, 430)와 가동부(240, 440) 사이의 인력도 더 강해질 수 있다. 이로 인하여, 전자 접촉기(100)에 과전류가 인가되더라도, 고정부(230, 430)와 가동부(240, 440)의 접촉이 유지될 수 있다. 따라서, 고정부(230, 430)와 가동부(240, 440)가 전자 반발력에 의해 상호로부터 분리되는 것이 방지될 수 있다. 아울러, 전자 접촉기(100)에서 아크가 발생되는 것이 방지될 수 있다. According to various embodiments, in the magnetic contactor 100, the magnetic parts 250 and 450 may maintain contact between the fixing parts 230 and 430 and the movable parts 240 and 440. That is, when the movable parts 240 and 440 contact the fixed parts 430 and 440, current may flow in the movable parts 240 and 440 between the fixed terminals 231, 233, 431, and 433. In addition, a magnetic field may be formed around the direction of the current in the movable parts 240 and 440. Through this, the magnetic parts 250 and 450 may be magnetized by a magnetic field, thereby generating a magnetic force. In addition, due to the magnetic force of the magnetic parts 250 and 450, an attraction force may be generated between the fixed parts 230 and 430 and the movable parts 240 and 440. Accordingly, the contact between the fixed parts 230 and 430 and the movable parts 240 and 440 may be maintained based on the magnetic force of the magnetic parts 250 and 450. In this case, when an overcurrent is applied to the magnetic contactor 100, the magnetic force of the magnetic parts 250 and 450 becomes stronger, and the attraction force between the fixed parts 230 and 430 and the movable parts 240 and 440 may also be stronger. . Thus, even if an overcurrent is applied to the electromagnetic contactor 100, the contact between the fixed parts 230 and 430 and the movable parts 240 and 440 may be maintained. Therefore, the fixing parts 230 and 430 and the movable parts 240 and 440 can be prevented from being separated from each other by the electron repulsive force. In addition, the generation of an arc in the electromagnetic contactor 100 can be prevented.
