Circuit-breaker electric-operating-mechanism wireless control and decompression protective device

Abstract

A circuit-breaker electric-operating-mechanism wireless control and decompression protective device is disclosed. The device comprises an electric operating mechanism (1) and a circuit breaker (2). The device is characterized in that the electric operating mechanism (1) is connected to a wireless controller (4) through an inlet wire terminal (3); the wireless controller (4) uses a received opening and closing signal to realize control of the electric operating mechanism (1) through the inlet wire terminal (3); a tripping coil (6) is installed in the wireless controller (4); and the tripping coil (6) can control the electric operating mechanism (1) so as to control opening of the circuit breaker. In the invention, a server provides a wireless control module signal so as to control the electric operating mechanism, wireless communication and control are realized, wrong wiring because of too many lines is avoided and a space is saved. Simultaneously, a condition in an electric power circuit can be effectively monitored and real-time feedback is achieved. After power is off, the circuit breaker is disconnected so as to guarantee safety of equipment. An existing circuit can be used and rewiring is not needed. A purpose of rapidly carrying out butt joint on intelligent equipment is realized.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical equipment, and in particular relates to a wireless control and voltage loss protection device for an electric operating mechanism of a circuit breaker. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, commonly known as "air switch", also refers to low-voltage circuit breaker. It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to ...
