Abstract

The embodiment of the invention provides a breaker divide-shut brake motion instruction device in a high-voltage switch cabinet. The device comprises a flash small bus, a control switch, a first indication lamp and a second indication lamp. The flash small bus and the indication lamp are added in an original breaker control circuit, different contacts of the control switch are connected with the flash small bus and the indication lamp, the non-correspondence principle of the breaker and the control switch when the breaker performs automatic divide-shut brake is employed to achieve flicker of the indication lamp so as to allow operators to visually obtain the divide-shut brake motion of the breaker being manual operation or automatic operation through different light-emitting modes of the indication lamp.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electrical control, and more specifically, relate to an opening and closing action indicating device for a circuit breaker in a high-voltage switch cabinet. Background technique [0002] The existing high-voltage switchgear (such as KYN28 high-voltage switchgear) controls the small busbar to basically meet the control requirements of the circuit breaker, including: (1) The closing and tripping coils of the circuit breaker are designed according to the short-term energization, that is, the opening and closing The gate switch is reset quickly after the action, so as to avoid the coil from burning out when tripping or closing; (2) There is a monitoring circuit for the control power supply. Once the control power supply loses power, the circuit breaker will not be able to operate, and an audible and visual signal will be sent to remind the relevant personnel in time. (3) There is an obvi...
