Description

전류 검출장치Current detector

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 일실시예로서의 전류검출 장치의 일부분해 사시도,1 is a partial perspective view of a current detection device as an embodiment of the present invention,

제2도의 (가), (나), (다)는 실시예의 전류 검출 장치의 케이스 조립 상태를 나타내는 설명도,2A, 2B, and 3C are explanatory diagrams showing a case assembly state of the current detection device of the embodiment;

제2도의 (라)는 상기 케이스의 덮개의 형상을 나타내는 평면도,2D is a plan view showing the shape of the lid of the case;

제3도는 외철형(外鐵型) 트랜스에의 전선 장착 상태를 나타내는 사시도.3 is a perspective view showing a state in which electric wires are mounted in an external iron transformer.

Claims (1)

본체와 덮개로된 개폐가능한 케이스에 외철형 트랜스를 검출부로 하는 전자회로를 구성하는 전류 검출장치로서, 상기 외철형 트랜스의 철심을 E형철심과 I형철심으로 구성하며, 상기 E형 철심과 여기에 권회된 코일을 상기 케이스의 상자에 수납함과 동시에, 상기 I형 철심물 상기 케이스의 덮개에 부착하고, 상기 코일을 그 철심 높이보다 낮게 형성하여 그 코일의 상부에 전류 검출의 대상으로 되는 전선을 상기 철심에 감아붙일수 있는 공간을 형성하며, 그 전선에 흐르는 전류에 의해 상기 코일에 유도되는 전류를 증폭하는 신호 증폭 회로와, 그 증폭된 신호가 소정의 크기 이상으로 되었을 때 적어도 소정시간은 온(ON)신호를 출력하는 검출수단을 갖춘 전류 검출 장치.A current detecting device comprising an electronic circuit having an outer iron transformer as a detecting unit in an openable and closed case including a main body and a cover, wherein the iron core of the outer iron transformer comprises an E-type iron core and an I-type iron core, wherein the E-type iron core and excitation The coil wound in the box is housed in a box of the case, and the wire of the I-type iron core is attached to the cover of the case. A signal amplifying circuit which forms a space to be wound around the iron core, and amplifies a current induced in the coil by a current flowing through the wire, and at least a predetermined time when the amplified signal becomes a predetermined magnitude or more; Current detection device having a detection means for outputting the (ON) signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
