Abstract
The utility model relates to a buffering device for a heavy-current indoor high-voltage vacuum circuit breaker, comprising a base, a gate, a connecting rod connected with the gate, and a buffer fixedly connected with the base; the buffer is provided with a buffering crank arm, the buffering crank arm is articulated with the connecting rod by a sunk pin, one end of the sunk pin is provided with a double nut, and an elastic piece is arranged between the double nut and the sunk pin. In the utility model, the double nut is adopted at one end of the sunk pin which penetrates through the connectingrod and is locked by a cap, and a disc spring is used for buffering, the impact on the sunk pin in the switching-on and switching-off processes of the vacuum circuit breaker is adsorbed by the disc spring; meanwhile, a stop nut is arranged on a sunk screw of an oil buffer, so as to lead the buffer not to be loose in the a plurality of times of switching-on and switching-off processes of the vacuumcircuit breaker.
Description
Technical field
The utility model relates to big electric current indoor high-voltage vacuum circuit breaker, relates in particular to a kind of big electric current indoor high-voltage vacuum circuit breaker buffer unit.
Background technology
Existing big electric current indoor high-voltage vacuum circuit breaker adapted spring operating mechanism, during breaker open operation, buffering connecting lever and oil bumper multiple impact only adopt the fixedly connected oil bumper of sunk screw easily to become flexible, and cause coming off.
Existing big electric current indoor high-voltage vacuum circuit breaker is on/off switch repeatedly, is repeatedly impacted with pin on the connecting rod that is connected of buffering connecting lever, and sells end riveted joint, and is not too reliable, easily becomes flexible slippage and falls.
The utility model content
The technical problems to be solved in the utility model is: a kind of novel structure, reasonable in design, dependable performance, big electric current indoor high-voltage vacuum circuit breaker safe in utilization are provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of big electric current indoor high-voltage vacuum circuit breaker buffer unit, comprise base, lock, the connecting rod that is connected with lock, the buffer of fixedlying connected with base, this buffer is provided with the buffering connecting lever, buffering connecting lever and connecting rod are hinged by the countersunk head pin, and described countersunk head pin one end is provided with double nut, is equipped with elastic component between described double nut and the countersunk head pin.
According to another embodiment of the present utility model, big electric current indoor high-voltage vacuum circuit breaker comprises further that with buffer unit described elastic component is the butterfly spring.
According to another embodiment of the present utility model, big electric current indoor high-voltage vacuum circuit breaker comprises further that with buffer unit described buffer is fixed on the base by sunk screw, has connected stop nut on the described sunk screw.
According to another embodiment of the present utility model, big electric current indoor high-voltage vacuum circuit breaker comprises further that with buffer unit described buffer is an oil bumper.
The utility model has solved the defective that exists in the background technology, and an end that runs through the pin of connecting rod adopts double nut and cap locking, and cushions with the dish spring, and the impact that pin bears in vacuum circuit-breaker on/off switch process is absorbed by the dish spring; Simultaneously on the oil bumper sunk screw, stop nut has been installed, thereby oil bumper under repeatedly impacting, the vacuum circuit-breaker on/off switch can not get loose.
