Abstract

The invention relates to a reclosing device for a small-size residual-current circuit breaker.The reclosing device is characterized by comprising a bottom cover and a cover body connected with the bottom cover. A circuit board, a handle shifting wheel, an outlet wiring terminal, an inlet wiring terminal, an N-pole switch and a drive mechanism are arranged in the bottom cover and the cover body. The drive mechanism comprises a semi-circle bevel gear and a gear motor, an output shaft of the gear motor is sleeved with a transmission gear, and the transmission gear is meshed with the semi-circle bevel gear; the handle shifting wheel and the semi-circle bevel gear are arranged in an attached mode, the end face, facing towards the handle shifting wheel, of the semi-circle bevel gear is provided with an arc-shaped limiting groove, the end face, facing towards the semi-circle bevel gear, of the handle shifting wheel is provided with an arc-shaped boss capable of reciprocating along the arc-shaped limiting groove, and the handle shifting wheel is connected with a connection rod. The reclosing device for the small-size residual-current circuit breaker has the advantage that the requirements for opening and closing the small-size residual-current circuit breaker through remote signal control are effectively satisfied.

Description

technical field [0001] The invention relates to the field of automatic control of low-voltage electrical appliances, in particular to a small leakage circuit breaker reclosing device. Background technique [0002] Domestic power supply network terminal actuators are generally small molded case circuit breakers or small leakage circuit breakers, the main models are C45 (DZ47), C65 and DZ47LE and other series. This type of product only has the function of automatic tripping protection for short circuit, overload, or leakage, but does not have the function of remote control opening and closing. With the development of my country's intelligent low-voltage networked power distribution, and the intelligent power distribution system's requirements for full-current selective protection of the power supply network, there is an urgent need for terminal actuators with remote control opening and closing functions. [0003] At present, there is no reclosing device applied to small leaka...
