Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] First, a trip cause indication device for a thermal-magnetic trip unit according to an embodiment of the present invention will be described.

[0020] According to one aspect of the present invention, there is provided a tripping reason indicating device for a thermal-magnetic tripper, including an overload indicator, the overload indicator includes a heat monitor, and when an overload fault occurs, the thermal-magnetic tripper Tripping, at the same time, the heat monitor detects the heat caused by the overload fault, and triggers the overload indicator to indicate that the cause of the trip is overload; the short circuit indicator, the short circuit indicator includes an electromagnetic monitor, when a short circuit fault occurs, the thermal magnetic type The release trips, and at the same time, the short circuit monit...

Abstract

The invention includes: an overload indicator comprising a thermal monitor for use in indicating the thermo-magnetic release to drop out at the time of overload and triggering the overload indicator to show the reason of drop out is caused by overload; a short circuit indicator comprising an electro-magnetic monitor for use in indicating the thermo magnetic release to drop out at the time of short circuit failure and triggering the short circuit indicator to show the reason of drop out is caused by short circuit.

Description

technical field [0001] The present invention relates to a thermal-magnetic release, more specifically, to a cause indicating device for a thermal-magnetic release that can indicate the cause of a trip and a release using the device. Background technique [0002] The thermal magnetic release of the circuit breaker (hereinafter referred to as the release, and the release referred to in this article refers to the thermal magnetic release) is still an important part of the development of circuit breakers today. A series of new functions of the release The development of the release is very necessary and timely. The tripping function of the release is divided into two parts, one is overload tripping; the other is short-circuit tripping. The release of the traditional circuit breaker uses a series of mechanical actions to make the bimetal or a jumper directly push the drawbar of the operating mechanism of the circuit breaker to perform the tripping action of the circuit breaker. ...
