이와같이 구성된 본고안의 작용효과를 설명하면 다음과 같다. 즉, 평상시에는 제2도에서와 같이 인입선(L1) 전원이 전압코일(1)과 전류코일(2) 및 1차코일(C1)을 통하여 배선단자(6)로 인입되며 인입선(L2) 전원은 2차코일(C2)과 4차코일(C4)을 통하여 배선단자(6a)로 인입되여 정상적인 전류가 흐르게되는 것이나, 만약 배선단자(6), (6a) 측에서 누전이 되면 1, 2차코일(C1), (C2)에는 누전량만큼의 전류가 흐르게 됨에 따라 1, 2차 코일에 흐르는 전류의 차이로 전자석(7)에서는 자력이 생겨 견인편(13)을 당기게 되므로 랙기어(14)와 치합된 지시침(15)이 회동되어 누전량에 해당하는 표시눈금(16a)을 지시해주고 합선으로 인한 과전류가 흐르게 되면 전자석(7)의 강한 자력에 의하여 견인편(13)이 더욱 당겨지므로 제3도에서와 같이 지시침(15)이 지시침 접지단자(17)에 접지되어 인입선(L2)의 약전이 배전선을 통하여 3차코일(C3)과 5차코일(C5)로 표시등(19a)에 인가되어 점등이 되는 것이며, 표시등(19)에도 인가되어 점등과 동시, 스위치편(20)과 흡착편(10)을 당기게 되므로 접리단자편(8), (8a)이 배선단자(6), (6a)에서 떨어지게 되어 배전선에 전원이 차단된다.The operational effects of the proposed paper thus constructed are as follows. That is, normally, as shown in FIG. 2, the lead wire L 1 power is introduced into the wiring terminal 6 through the voltage coil 1, the current coil 2, and the primary coil C 1 , and the lead wire L 2. ) Power is drawn into the wiring terminal 6a through the secondary coil (C 2 ) and the fourth coil (C 4 ) so that a normal current flows, but if a short circuit occurs in the wiring terminals (6) and (6a) As the current flows through the primary and secondary coils (C 1 ) and (C 2 ), the magnetic current is generated in the electromagnet (7) due to the difference in the current flowing through the primary and secondary coils. Therefore, the indicator gear 15 engaged with the rack gear 14 rotates to indicate the indication scale 16a corresponding to the amount of the short circuit, and when an overcurrent due to a short circuit flows, the traction piece 13 ), The indicator needle 15 is grounded to the indicator needle ground terminal 17 as shown in FIG. 3 so that the weak charge of the lead wire L 2 is transferred to the tertiary coil C through the distribution line. 3 ) and the fifth coil (C 5 ) is applied to the indicator light (19a) is turned on, and is also applied to the indicator light (19) and at the same time as the light is pulled the switch piece 20 and the suction piece (10) The folding terminal pieces 8 and 8a are separated from the wiring terminals 6 and 6a so that the power supply is cut off from the power distribution line.
그리고 배전선에 인입선(L1), (L2) 전원이 차단되드라도 배전선에서의 합선상태를 제거하지 아니하는 한 3차코일(C3)과 5차코일(C5)에는 인입선(L1), (L2)의 약전 전류가 흐르기 때문에 전자석(7)에 자력이 생겨 스위치편(20)이 이 교류의 특성에 따라 진동되면서 부저와 같은 경보음을 발생하게 된다.And drop line (L 1) to the distribution line, (L 2) power supply is cut off doedeu even have lead-tertiary coil (C 3) and the fifth coil (C 5) which do not remove the short-circuit state in the distribution line (L 1) Since the weak electric current of (L 2 ) flows, a magnetic force is generated in the electromagnet 7, and the switch piece 20 vibrates according to the characteristics of this alternating current to generate an alarm sound like a buzzer.
따라서 본고안은 누전으로 인한 소비전력량이 적산계기(4)에 환산될 뿐만아니라 누전량을 검출기(16)로 확인할수 있으며 과전류 발생시에는 배전선에 입력 전원을 차단함과 동시에 표시등(19), (19a)이 점등되고 경고음이 발생되므로 주위사람의 주의력을 환기시켜 즉시 보수에 임하도록 함으로써 누전으로 인한 전류손실과 사고를 미연에 방지할 수 있는 이점이 있다.Therefore, this paper not only converts power consumption due to leakage into the totalizer 4, but also can check the leakage by the detector 16. When an over current occurs, the input power is cut off at the distribution line and the indicator (19), ( Since 19a) is turned on and a warning sound is generated, there is an advantage of preventing current loss and accidents due to short-circuit by arousing the attention of the people around them and promptly performing repairs.
