Embodiment Construction

[0029] The shell part is installed on the upper end of the entire circuit breaker, responsible for supporting the internal conduction structure of the entire circuit breaker, and can realize the on-off operation and status monitoring of the circuit breaker.

[0030] The specific embodiment is that when the operating rod part of the housing part is manually pulled, the movable contact part in the housing part moves horizontally along the direction of the contact point 61 of the base part 6 of the circuit breaker along the guide shaft on the housing part, which is the same as the circuit breaker. Contact 61 of the base part 6 of the device, so that the contact on the base part 6 is connected with the concave movable contact seat on the housing, and continue to pull the manual operating lever part to make the concave movable contact seat and the base The contacts on the part 6 are compacted, and now the jacking spring 54 at the bottom of the concave movable contact seat is compres...

Abstract

The invention relates to a shell part used for multi-phase control of a circuit breaker. The shell part comprises a manual operation rod part (1), a normal close monitoring part (2), a normal open monitoring part (3), a shell (1) and a moving contact part (5). The shell part is applied to the circuit breaker or a switch; multi-phase contacts are distributed in a delta shape, and a spring is addedto the bottom of each contact, so that a contact pressure of each contact and outside is increased; and the normal close and normal open monitoring parts are added to the shell, so that the on or offstate of the circuit breaker or the switch can be monitored in real time.

Description

technical field [0001] The invention belongs to the field of aviation power distribution, is particularly suitable for circuit breakers or switches with large current control and small product volume, and specifically includes a housing part for multi-phase control circuit breakers. Background technique [0002] With the increase of electrical equipment and demand for electricity, the current load in the transmission line continues to increase, resulting in an increasing demand for high-load circuit breakers. At present, to cope with the demand of high load, all circuit breaker manufacturers increase the volume of the circuit breaker proportionally on the basis of the original circuit breaker layout, which leads to an increase in the volume of the circuit breaker. For some occasions, circuit breakers with increased volume are not suitable for applications. For example, high-performance and small-volume circuit breakers are required in compact equipment such as aerospace, avi...
