Problems solved by technology

The drawer seat of the original intelligent low-voltage universal circuit breaker is a grooved wheel structure. When the drive wheel and the drive plate are driven, there is sliding friction between the shifting teeth and the card slot. It is very large, on the one hand, it will make it more difficult for the operator to operate the cradle, and on the other hand, it will also shorten the operating life of the cradle

Abstract

The invention discloses a transmission device for reducing cranking torque of a draw-out socket of a universal circuit breaker. A circuit breaker body is provided with an insert pole, the draw-out socket is provided with a contact, the circuit breaker body is connected with a transmission device, each of a transmission wheel and a transmission plate comprises a non-contact section and a contact section, a transmission wheel of the non-contact section is provided with a plurality of extraction teeth, a transmission plate of the non-contact section is provided with a plurality of clamping grooves corresponding to the extraction teeth, a transmission wheel and a transmission plate of the contact section are provided with standard gears, which are mutually meshed and connected, the circuit breaker body is connected with a sliding plate, and the sliding plate is connected with the transmission plates. The insert pole non-contacts with the contact in a geneva wheel transmission manner, the transmission wheels and the transmission plates are in gear transmission during process of primary contact to complete contact, operating force is reduced by changing the transmission manner, and accordingly transmission efficiency is higher and cranking operation is more stable and safer.

Description

technical field [0001] The invention relates to the field of universal circuit breakers, in particular to a transmission device for reducing the rocking torque of a drawer base of the universal circuit breaker. Background technique [0002] When the body of the intelligent low-voltage universal circuit breaker is shaken from the disconnected position to the connected position in the drawer seat, when the inserting knife on the circuit breaker body is just in contact with the contact of the drawer seat, the rocking torque of the drawer seat is the largest at this time, and then decrease. The drawer seat of the original intelligent low-voltage universal circuit breaker is a grooved wheel structure. When the drive wheel and the drive plate are driven, there is sliding friction between the shifting teeth and the card slot. It is very large, on the one hand, it is more difficult for the operator to operate the cradle, and on the other hand, the operating life of the cradle will ...
