B type intelligent circuit breaker with automatic switching-in function

Abstract

The invention relates to a B type intelligent circuit breaker with automatic switching-in function, which comprises a circuit breaker body, wherein the circuit breaker body comprises an upper cover, a handle, a bottom box and a bearing plate, wherein the upper cover is provided with a notch, two ends of which correspond to the opening / closing positions of the circuit breaker; the handle extends out of the notch; the bottom box is provided with a circuit breaker actuating mechanism, an incoming line terminal and an outgoing line terminal, and the circuit breaker actuating mechanism is triggered by the handle; the bearing plate is arranged between the upper cover and the bottom box, and is provided with a pinion and rack mechanism and a pushing part, and the pushing part is connected with the handle; and the bottom box is internally provided with a motor which is controlled by an automatic switching-in control unit, and the pinion and rack mechanism converts the rotation of the motor into the reciprocating motion of the pushing part, so that the handle is shifted between the opening / closing states.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker in which the motor capable of realizing the automatic closing function is placed in the bottom box and the handle is exposed. 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 end...

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, and the user needs to handle it by himself, which brings inconvenience to the user;

[0006] 2. In the event of abnormal power consumption conditions such as excessive temperature, the existing 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
