Built-in A type intelligent circuit breaker with automatic closing function

Abstract

The invention relates to a built-in A type intelligent circuit breaker with automatic closing function. The circuit breaker comprises a circuit breaker body and a bearing plate, wherein the circuit breaker body comprises a box body which is provided with a circuit breaker actuating mechanism, an incoming line terminal and an outgoing line terminal, the circuit breaker actuating mechanism is triggered by a shifter lever in the box body; the bearing plate is arranged between a upper cover and a bottom chamber and is provided with a crank part and a stirring part, the stirring part is connected with the shifter lever; the inside of the bottom chamber is provides with an electric motor, and the rotation of the electric motor is converted to the reciprocating action of the stirring part by the crank part under the control of an automatic closing control unit so as to realize the on / off state switch of the shifter lever.

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 toggle rod is not 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...

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
