본 고안은 전원을 공급받는 수전라인에 순간전압강하 또는 순간 정전등의 장애로 인해 부하측(전기 및 전자기기)에 미치는 악영향을 배체키 위한 것으로, 특히 2개의 전원공급라인을 갖고 정전허용 시간이 4m Sec 이상을 허용할수 없는 부하를 사용하는데 적합한 무접점 전환스위치에 관한 것이다.The present invention is designed to distribute the adverse effects on the load side (electric and electronic devices) due to an interruption such as an instantaneous voltage drop or an instantaneous blackout in a power supply line. Especially, two power supply lines have an allowable time of 4m A contactless changeover switch suitable for use with a load that cannot tolerate more than sec.
주지된 바와 같이 수전라인에서 순간전압강하 또는 순간 정전이 전기 및 전자기기에 미치는 영향을 제4도에서 살펴보면, 첫째: 제4도에서 ①은 CPU를 사용한 자동화기기에 10-20% 이상의 전압강하가 0.004-0.02초 이상계속되면 CPU가 정지되고 자동화제어용 컴퓨터가 정지되어 조업이 중단된다, 둘째: 제4도에서 ②는 전자 개폐기에 50%이상의 전압강하가 0.005-0.02초 이상 계속되면 전자개폐기가 동작되고 전동기가 정지되며 생산이 중지된다. 셋째: 제4도에서 ③은 반도체 사용 가변속전동기에 20%이상의 전압강하가 0.005-0.03초 이상 계속되면 전동기가 정지되어 공장의 조업, 엘리베이터 등이 정지된다. 넷째: 제4도에서 ④는 고압방전등에 20-30% 이상의 전압강하가 0.005초 이상 계속되면 소등되고 다시 점등되려면 고압증기방전램프이기 때문에 어느 이상 전압강하가 발생하면 곧 전원이 회복되어도 발광관이 냉각되었다가 재점등되기까지는 수분 내지 수십분이 필요하다.As shown in FIG. 4, the effect of the instantaneous voltage drop or the momentary power failure on the power receiving line in electric and electronic devices is as follows. If it lasts longer than 0.004-0.02 seconds, the CPU is stopped and the computer for automation control stops and operation stops. Second: In Figure 4, ②, when the voltage drop of more than 50% continues over 0.005-0.02 seconds, the electronic switch operates. The motor is stopped and production is stopped. Third: In Figure 4, ③ indicates that if the voltage drop of more than 20% is continued for more than 0.005-0.03 seconds for the variable speed motor using semiconductor, the motor is stopped and the operation of the factory, the elevator, etc. are stopped. Fourth: ④ in Fig. 4 is a high-pressure steam discharge lamp that turns off when the voltage drop of 20-30% or more continues for more than 0.005 seconds in the high-pressure discharge lamp. It takes several minutes to several tens of minutes to cool before re-lighting.
이와 같이 수전라인의 순간전압강하 및 순간정전발생으로 야기되는 문제는 매우 심각한 것이라 할수 있는데 특히 상기 넷째 항의 고압방전등(예컨대, 수은등, 고압나트륨등등)을 사용하는 것(운동경기장의 야간 경기시의 라이트, 차량이 통행하는 터널의 조명등)에서는 상기의 문제가 발생하면 그 파급효과가 대단히 커지기 때문에 고가의 발전기나 무정전 전원 장치가 채용되어 왔던 것이다.The problem caused by the instantaneous voltage drop and the occurrence of momentary power failure of the power receiving line is very serious. In particular, the use of the high-pressure discharge lamp (eg, mercury lamp, high pressure sodium lamp, etc.) of the fourth term (light during the night race of the sports stadium In the case where the above problems occur, the ripple effect is greatly increased. Therefore, expensive generators or uninterruptible power supplies have been adopted.
여기에서 제2도에 표시한 종래의 무정전 전원장치는 교류입력이 순간정전 또는 전압강하되면 축전지의 출력이 역변환부(B)에 의해 변화출력되어 부하에 전원을 계속 공급 토록된 것으로서 매우 고가이고 그 효율이 약80%정도에 불과하였다.In the conventional uninterruptible power supply device shown in FIG. 2, when the AC input is momentarily interrupted or the voltage drops, the output of the battery is changed and output by the inverse converter B so that power is continuously supplied to the load. The efficiency was only about 80%.
제3도에 표시한 종래의 부서터 방식의 순간 전압강하 보상기는 순간전압강하된 전압치를 변압기에 의해 보상하여 항상 일정한 전력이 공급되도록 한 것으로서 그 효율은 약 85%정도이며 상기 제2도의 무정전 전원장치에 비해 약간 저렴하나 비교적 고가이었으며 또한 양자는 주로 소전력에만 사용이 가능하였고 대전력에는 사용치 못하였던 결점이 있었다.As shown in FIG. 3, the conventional voltage drop compensator of the breaker type compensates the voltage drop of the voltage drop by a transformer so that constant power is always supplied. The efficiency is about 85% and the uninterruptible power supply of FIG. It was slightly inexpensive compared to the device but relatively expensive, and both could only be used for small power and not for large power.
본 고안은 상기한 제반 문제점을 해소키 위한것으로서, 저렴한 생산가로 상기 무정전 전원장치나 전압보상기의 양기능을 만족시킬수 있음과 동시에 대전류용으로 사용이 가능하고 수전라인의 장애에 대한 라인 전환속도가 지극히 신속토록 된 것으로, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is intended to solve the above problems, and it is possible to satisfy both functions of the uninterruptible power supply or voltage compensator at a low cost, and to be used for large currents, and the line switching speed for failure of the power line is extremely high.

즉 스위치(S1)은 ON, 상태이고 스위치(S2) 및 반도체스위치(S3)은 OFF 상태에서 수전라인(L1)에서 부하(3)에 전원을 공급하고 있는 상태라 가정할 때, 상기 수전라인(L1)에 순간정전 및 전압강하가 발생하게되면 공지의 검출수단(도시치 않았음)의 정보를 제어회로(1)는 각 검출단(VL1,VL2), (IL1,IL2), (PL1,PL2), (Ps)을 통해 판독하여 출력단에 제어명령을 전달하며 따라서 스위치 전환지령단(Os), 반도체스위치구동지령단(Os3)은 출력을 발생케 된다.That is, suppose that the switch S 1 is ON, and the switch S 2 and the semiconductor switch S 3 are in the OFF state, supplying power to the load 3 in the power receiving line L 1 .

한편, 반도체스위치(S3)는 그 ON, OFF작동이 매우 고속(수 m Sec∼수 m Sec)으로 이루어지므로 부하(3)에 악영향이 없이 정상전력공급은 이룰수 있게 되고 병설된 스위치(S2)에 의해 전원연결의 신뢰도가 매우 높게 되며, 이때 스위치(S1)(S2)의 전환상태가 상태표시판(4)에 의하여 파악이용토록 되어 있다.On the other hand, since the semiconductor switch S 3 is operated at a very high speed (a few m Sec to a few m Sec), the normal power supply can be achieved without adversely affecting the load 3 and the parallel switch S 2 is provided. Reliability of the power connection is very high, and the switching state of the switch (S 1 ) (S 2 ) is grasped and used by the status display board (4).
