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

Abstract

The invention discloses an intelligent micro-breaker with an automatic switching-on function. The micro-breaker comprises a breaker body, wherein the breaker body comprises a case, the case consists of an upper cover and a bottom case, a breaker action mechanism which is used for switching the on / off state of the breaker, a line inlet end and a line outlet end are arranged in the case, the case also comprises a part with an automatic switching-on function, the part with the automatic switching-on function consists of an automatic switching-on mechanical unit and an automatic switching-on control unit, the automatic switching-on mechanical unit comprises a motor and an intermediate transmission mechanism, the motor runs through the automatic switching-on control unit, the transmission is achieved through the intermediate transmission mechanism, then the breaker action mechanism is driven to act, and the switching-on action of the breaker is achieved.

Description

Technical field [0001] The invention relates to a circuit breaker, which is applicable to both three-phase and single-phase circuit breakers, and particularly relates to a circuit breaker capable of realizing an automatic closing function. Background technique [0002] For the power sector, the switch and circuit breaker equipment is an essential equipment to ensure the safety of electricity use and switch lines. With the introduction of the country's smart grid plan, the need for circuit breaker equipment to move towards smart words is an important direction. [0003] See Figure 1A with Figure 1B As shown, it is a circuit breaker in the prior art, and we call it the 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 opened with a slot 1...
