Abstract

The invention provides a miniature circuit breaker control device. Through movement of a sliding block on a screw rod, a switch-off driving mechanism and a switch-on driving mechanism are respectively driven to complete switch-off and switch-on operations on a circuit breaker; after the switch-off and switch-on operations are completed, the sliding block returns to an original position, and a transmission relation with the switch-off driving mechanism or the switch-on driving mechanism is disconnected; since the transmission relation is disconnected, an internal part of the miniature circuit breaker control device cannot stop the action of a switch-off and switch-on mechanism of the miniature circuit breaker any longer, thus, a handle of the miniature circuit breaker still can be manually operated to achieve switch-off and switch-on after the switch-off and switch-on operations of the miniature circuit breaker are controlled. With the miniature circuit breaker control device provided by the invention, the manual switch-off and switch-on still can be fulfilled on the condition of a fault occurs in the miniature circuit breaker control device without affecting original manual control of the miniature circuit breaker, and the safety performance is improved. Moreover, the invention also provides a method applying the above miniature circuit breaker control device to control the miniature circuit breaker.

Description

technical field

[0001] The invention relates to the technical field of electrical switches, in particular to a miniature circuit breaker control device and a method for controlling a circuit breaker using the device. Background technique

[0002] The miniature circuit breaker is the most widely used terminal protection device in the building electrical terminal power distribution device. The miniature circuit breaker is composed of opening and closing mechanism, contacts, protection devices (various releases and current heating components), arc extinguishing system, etc.

[0003] Its working principle is: use the protection device (release) and the current heating component to realize overload and short circuit protection. When the current passing through the coil in the current heating component is greater than the set current value, the moving iron core of the electromagnetic release will act , Push the striking lever to hit the operating mechanism, unlock the operating m...
