Description

교류 삼상전동기의 운전 정지회로Operation stop circuit of AC three-phase motor

제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.

본 고안은 특수반도체 3극으로 된 교류 제어용소자(TRIAC)를 사용한 교류 삼상전동기의 운전, 정지(ON, off)회로에 관한 것으로 본 고안은 설치기기와 조작부가 격리되어 있을뿐 아니라 종전의 전자접촉기(Magnet Switch)와는 달리 접점이 없으므로 아크(ARC)가 생기지 않아 화재예방을 할 수 있는 특징을 가지고 있는 것으로 이를 회로도에 의거하여 상세히 설명하면 다음과 같다.The present invention relates to the operation and stop (ON, off) circuit of an AC three-phase motor using an alternating current control element (TRIAC) consisting of three-pole special semiconductors. Unlike the (Magnet Switch), there is no contact, so there is no arc, which prevents fire.

푸시보턴 스윗치를 온(ON)하면 트랜스(Trans)에 전원이 공급되어 S1,S2,S3,S4에 유도전압이 발생되며 S1의 전압이 D1부리지에 정류되어 R1을 통하여 R2의 (1)(2)에 정류전압이 트라이악(TRIAC)의 케이트(G)(1)(2)에 접속되어 점호되면 TRIAC은 도통되어 푸시보턴 스위치를 온(ON)하므로서 자기보지회로가 유지되고 동시에 S2,S3,S4는 D2,D3,D4에 부리지 정류되어 R3,R5,R7을 거쳐 R4,R6,R8의 양단에 정류전압이 TRIAC(2)(3)(4)의 케이트(3)(4)(5)(6)(7)(8)에 접속되어 점호되며 TRIAC(2)(3)(4)는 도통되어 삼상전동기(Motor)는 운전상태로 들어간다.When the pushbutton switch is ON, power is supplied to the trans to induce voltages at S 1 , S 2 , S 3 , and S 4 , and the voltage at S 1 is rectified at the D 1 ground , When the rectified voltage is connected to the gate (G) (1) (2) of the triac (1) (2) of R 2 and is fired, the TRIAC conducts and turns on the pushbutton switch to turn on the self-holding circuit. At the same time, S 2 , S 3 , and S 4 are rectified in D 2 , D 3 , and D 4 , and the rectified voltage across the R 3 , R 5 , and R 7 , R 4 , R 6 , and R 8 is TRIAC. (2) (3) (4) is connected to and is connected to the Kate (3) (4) (5) (6) (7) (8) and the TRIAC (2) (3) (4) is conducted so that the three-phase motor ( Motor enters the running state.

정지시는 푸시보턴 스위치를 오프(off)하므로 트랜스(Trans)의 전원이 공급되어 일시에 차단이 되어 TRIAC2의 케이트애 점호가 되지 않으므로 자기보지는 차단되어 삼상전동기는 정지된다.Since the pushbutton switch is turned off at the time of stop, the power of Trans is cut off and it is temporarily cut off, so it is not controlled by Kate Ae of TRIAC 2 .

TRIAC2에 C,R과 세라믹 TNR2을 병렬로 접속하므로 서지전압을 흡수할 수 있고 전원 R.S.T상에 세라믹 TNR1을 접속하여 전자기기에 서지가 들어가지 못하게 폐회로를 만들게 되므로 안정성이 있고 자기보호가 된다.Since C, R and ceramic TNR 2 are connected to TRIAC 2 in parallel, it can absorb surge voltage and ceramic TNR 1 is connected to power supply RST to make closed circuit to prevent surge. do.
