Built-in circuit breaker with automatic switch-on function

Abstract

The present invention is a built-in circuit breaker with automatic closing function, which includes: a circuit breaker body, the circuit breaker body includes: an upper cover, the upper cover is provided with a slot, the The two ends of the slot correspond to the on / off position of the circuit breaker; a handle extends out of the slot; The on-off action mechanism of the circuit breaker is triggered by the handle; it also includes: a bearing plate, the bearing plate is arranged between the upper cover and the bottom box, and combined with an electric operating mechanism, the The electric operating mechanism described above has an actuating end, which is connected to the handle, and under the control of an automatic closing control unit, through the operation of the electric operating mechanism, the handle is opened / closed switch between off and off states.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker with an exposed handle capable of realizing an automatic closing function. Background technique [0002] For the electric power sector, switching and breaking equipment is an essential equipment to ensure the safety of electricity consumption and line switching. With the introduction of the country's smart grid plan, it is an important direction for circuit breaker equipment to move towards smart phones. [0003] see figure 1 As shown, it is a circuit breaker in the prior art, and we call it a circuit breaker body in the present invention. The circuit breaker can be three-phase or single-phase, and can be an ordinary miniature circuit breaker , it can also be a large switch, which includes: a box body, the usual box body is composed of an upper cover and a bottom box, the upper cover is provided with a slot, and the two ends of the slot correspond to the circuit breaker.

AI Technical Summary

Problems solved by technology

[0005]1. In the prepayment system, the circuit breaker cannot be automatically closed after the user pays the electricity fee, which needs to be handled by the user himself, which brings inconvenience to the user;

[0006]2. When abnormal power consumption conditions such as overheating occur, the current circuit breaker disconnects slowly;

[0007]3. If the abnormal situation of power consumption is not ruled out, the user can close the switch, which may bring potential safety hazards
