Abstract

본 발명은 코일제품이 얼마만한 서지(surge)전압에 견딜 수 있는 가를 시험해봄과 동시에 서지테스트시 코일제품에서 발생되는 자유진동 파형을 관측하여 코일제품 고유의 전기적 특성을 분석해 볼수 있도록 하기 위해 실시하는 서지테스트 방법의 새로운 기술에 관한 것으로, 시험하고저하는 코일(L2)의 양단부에 서지전압을 직접 인가하는 것이 아니고 시험코일(L2) 내부에 철심(1)(ferrite 코어나 공심(空芯) 코어포함)을 삽입하여 여기에 자력변화를 주기위한 전류코일(L1)을 권착하여 시험코일과 전류코일이 철심을 통해 전자적 결합상태가 형성되게 만들고 전류코일(L1)의 양단에는 공급전원 충전회로와 이를 제어하는 고속스위치(SCR)를 장치하여 공급전류를 스위치로 제어할 수 있게 하고 시험코일(L2) 양단에는 분압회로(C1)(C2)와 오실로스코프(3)를 장치하여서된 코일제품의 서지테스트(surge test) 방법이다.The present invention examines how much surge voltage the coil product can withstand and at the same time observes the free vibration waveform generated from the coil product during the surge test to analyze the electrical characteristics of the coil product. It relates to a new technique of the surge test method, and does not directly apply a surge voltage to both ends of the coil (L2) to be tested, but instead of an iron core (ferrite core or a hollow core) inside the test coil (L2). Insert a current coil (L1) to change the magnetic force to form an electromagnetic coupling state between the test coil and the current coil through the iron core, and the supply power charging circuit and both ends of the current coil (L1) A high speed switch (SCR) to control the supply current can be controlled by a switch, and a voltage divider circuit (C1) (C2) and an oscilloscope (3) are provided at both ends of the test coil (L2). A surge test (surge test) of the coil yeoseo production methods.

Claims (1)

시험하고저하는 코일(L2)의 양단부에 서지전압을 직접 인가하는 것이 아니고 시험코일(L2) 내부에 철심(1)(ferrite 코어나 공심(空芯) 코어포함)을 삽입하여 여기에 자력변화를 주기위한 전류코일(L1)을 권착하여 시험코일과 전류코일이 철심을 통해 전자적 결합상태가 형성되게 만들고 전류코일(L1)의 양단에는 공급전원 충전회로와 이를 제어하는 고속스위치(SCR)를 장치하여 공급전류를 스위치로 제어할 수 있게하고 시험코일(L2) 양단에는 분압회로(C1)(C2)와 오실로스코프(3)를 장치하여서된 코일제품의 서지테스트(surge test).Instead of directly applying a surge voltage to both ends of the coil L2, the iron core 1 (including a ferrite core or a hollow core) is inserted into the test coil L2 to change the magnetic force therein. The current coil (L1) for the cycle is wound so that the test coil and the current coil are formed in an electronically coupled state through the iron core. Surge test of coil products by controlling the supply current with a switch and installing a voltage divider circuit C1 (C2) and an oscilloscope (3) across the test coil (L2). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
