Abstract

The invention discloses an operating mechanism of an electricity leakage reclosure circuit breaker, relating to the technical field of circuit breakers and overcoming the defects that the radial force of a motor rotating shaft of the existing electricity leakage reclosure circuit breaker is unbalanced to cause the damage of a motor. The operating mechanism comprises a handle and a motor which are arranged on a body, the handle is connected with the motor by a connecting rod, a ratchet wheel is arranged on the motor, the connecting rod is connected with a pawl through a crank, the ratchet wheel and the pawl are meshed, an elastic sheet is arranged between the connecting rod and the crank, and a manual push rod is arranged on the connecting rod; when the motor works, a multi-pawl structure can ensure the balance of radial force of the motor rotating shaft, thus avoiding the damage to the motor due to radial force generated in rotation of a crank connecting rod mechanism; when the motor is not needed to work, the ratchet wheel does not work when manual operation is adopted, the pawls and the ratchet wheel can be separated by rotating a shaft on the crank, so that the crank connecting rod mechanism can successfully run reliably towards one way.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an operating mechanism of a leakage reclosing circuit breaker. Background technique [0002] The operating mechanism of the leakage reclosing circuit breaker When the motor is working, the radial force of the motor shaft is unbalanced, and when the crank linkage mechanism of the motor rotates, the radial force generated damages the motor. Contents of the invention [0003] The purpose of the present invention is to provide an operating mechanism of an electric leakage reclosing circuit breaker to overcome the defects of the existing technology of low spring life. [0004] According to the above purpose, the technical solution adopted in the present invention is: an operating mechanism of an earth leakage reclosing circuit breaker, including a handle and a motor installed on the body, the handle is connected with the motor through a connecting rod, and it is characteriz...
