Description
Technical field
The utility model relates to breaker technical field, is specifically related to a kind of reclosing operation mechanism of residual current action breaker.
Background technology
In low voltage electric network, install residual current action breaker is the effective safeguard procedures of one preventing person electric shock, electrical fire and electric equipment from damaging.Now in low voltage electric network, vigorously promote the use residual current action breaker.But, possesses the residual current action breaker of reclosing function in the market, because its reclosing operation mechanism design is reasonable not, thus easily cause operating personnel's misoperation, and this reclosing operation mechanism also exists, and complex structure, structural design are not compact, the defect of unstable properties.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provide that a kind of structure is simple, stable performance, residual current action breaker compact to design reclosing operation mechanism.
For achieving the above object, the utility model adopts a kind of reclosing operation mechanism of residual current action breaker, comprise and be arranged on automatic reclosing gate assembly on breaker body and be movably arranged on manual knob on panel, described automatic reclosing gate assembly comprises the motor be arranged on breaker body, be arranged on the unilateral bearing on machine shaft, be sleeved on the sleeve of unilateral bearing outside, be welded on the short connecting rod on sleeve, long connecting rod, be arranged on the supporter on circuit breaker handle, one end of described long connecting rod is connected on one end of short connecting rod, the other end of described long connecting rod is bolted on described supporter, on the upper surface of described short connecting rod, the junction of corresponding short connecting rod and long connecting rod is fixedly installed pin, the upper surface of described manual knob is provided with the knob-operated hole be exposed at outside panel, and the lower end of manual knob is provided with the manual link matched with pin, described manual link can promote pin with manual knob and drive short connecting rod to rotate the manual reclosing realizing circuit breaker.
The beneficial effects of the utility model are: when machine operation, machine shaft drives short connecting rod to rotate clockwise by unilateral bearing, short connecting rod drives long connecting rod action, and long connecting rod drives circuit breaker handle to realize feed motion, namely realizes the automatic reclosing function of this residual current action breaker; When motor does not work, when adopting manual operation, operation spanner is inserted in knob-operated hole, clockwise turning operation spanner, operation spanner drives manual knob to rotate clockwise, and the manual link on manual knob promotes pin and drives short connecting rod to rotate clockwise, and short connecting rod drives long connecting rod action, long connecting rod drives circuit breaker handle to realize feed motion, namely realizes the automatic reclosing function of this residual current action breaker.The reclosing operation mechanism of this residual current action breaker has that structure is simple, stable performance, advantage compact to design, and manual, automatic reclosing function can be realized, and unilateral bearing is provided with on machine shaft, short connecting rod can only rotate clockwise, can not rotate counterclockwise, thus when adopting manual operation, the generation of operating personnel's misoperation can be avoided.
