Intelligent circuit breaker with automatic switching-in control unit

Abstract

The invention discloses an intelligent circuit breaker with an automatic switching-in control unit, which comprises a circuit breaker body and a circuit control board, wherein the circuit breaker body comprises a box body in which a circuit breaker action mechanism used for switching on / off states of the circuit breaker is arranged, an incoming line end and an outgoing line end; and the circuit control board is provided with the automatic switching-in control unit. The circuit breaker action mechanism is operated by controlling a motor and using an electrically operated mechanism; and the automatic switching-in control unit comprises a power supply acquisition subunit and a motor control subunit, wherein the power supply acquisition subunit acquires electric power signals from a phase line and performs rectifying and filtering treatments, and the motor control subunit acquires the electric power signals and makes the motor act when the motor control subunit receives a switching-in command, so the circuit breaker action mechanism generates switching-in actions at last.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker capable of realizing automatic closing function. Background technique [0002] For the power sector, the switch and breaker 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 the circuit breaker equipment to move towards intelligence. [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. The open / close position; a toggl...

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
