Abstract
PURPOSE:To perform a closing operation easily at the time of opening when an abnormal current is detected by mounting a trip detecting switch for detecting release from a trip link of a latch link, and supplying a power to energize a current in the opening direction to a bistable electromagnetic device through the trip detecting switch. CONSTITUTION:When a trip detecting switch 13 is closed, a current in the opening direction is sent to a coil 10c. A bistable electromagnetic device 10 is displaced from a closing position to an opening position by this current, and a latch link 11 released by link connection is moved by this displacement to be engaged with a trip link 12, and a change contact 14a of a change switch 14 is changed to an opening side contact 14c to be moved to an opening condition. If flow of an abnormal current such as a short circuit current or an overload current releases the trip link 12 from the engagement with the latch link 11, therefore, the bistable electromagnetic device 10 transfers to the opening condition, so it can be closed again only by an operation for changing from opening into closing.

〔産業上の利用分野〕
本発明は、外部操作スイッチの操作により開閉可能なリ
モートコントロール式回路遮断器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control type circuit breaker that can be opened and closed by operating an external operation switch.
一般に、電源と負荷とを接続する電路には、負荷又は配
線を保護する為に回路遮断器が装備されると共に、必要
に応じて負荷の開閉制御を行う為に外部操作スイッチに
より開閉動作する制御機器が装備される。Generally, the electrical circuit connecting the power source and the load is equipped with a circuit breaker to protect the load or wiring, and an external control switch is used to control the opening and closing of the load as necessary. equipment will be equipped.
一方、電路に回路遮断器及び制御機器の両者を装備する
ならば配線や施工等に手間が掛かる関係から、両機能を
満足するリモートコントロール式回路遮断器が使用され
始めた。On the other hand, if an electric line is equipped with both a circuit breaker and a control device, wiring and construction are time-consuming, so remote control type circuit breakers that satisfy both functions have begun to be used.

を特徴とするリモートコントロール式回路遮断器。(1) Equipped with a movable contact plate equipped with a movable contact that connects and separates from a fixed contact, and a plunger that is linked to the movable contact plate so that it can be driven to open and close. A bistable electromagnet device for displacing a stable position, and a trip link connected to an interlocking member extending from the plunger of the bistable electromagnet device to the movable contact plate, and detachably engaged with a trip link that responds when an abnormal current is detected. In a remote control type circuit breaker configured with a latch link that supports the operation of the interlocking member when engaged with the latch link and releases the operation of the interlocking member when disengaged from the circuit breaker, detachment of the latch link from the trip link is detected. 1. A remote control type circuit breaker, comprising a trip detection switch, through which power is supplied to the bistable electromagnet device so as to cause current to flow in the opening direction.
