With the rapid development of social economy, new technology and new materials are continuously generated, the power consumption demand of users is continuously increased, the power consumption load is continuously increased, and the high-capacity molded case circuit breaker is widely applied. Except when the circuit is cut off and power transmitted, fault handling, operation mode adjustment, equipment maintenance, all need operate this type of low-voltage circuit breaker, and because large capacity moulded case circuit breaker divide-shut brake spring effort is big, moulded case circuit breaker faces several outstanding problems at the divide-shut brake operation in-process:

1. the molded case circuit breaker must be operated laterally in the switching-on and switching-off process. Because the acting force of the opening and closing spring of the high-capacity molded case circuit breaker is large, the circuit breaker can not be opened or closed by an operator due to insufficient arm strength.

2. When the circuit breaker is forcibly opened and closed due to insufficient arm strength, an operator faces the equipment from the front side, and the operator is likely to have accidents to hurt the human body and influence the safe operation of the power grid.

Therefore, a moulded case circuit breaker divide-shut brake booster that labour saving and time saving, operating efficiency is high, and the security is good awaits urgent study.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that the moulded case circuit breaker among the prior art is difficult for divide-shut brake, divide-shut brake inefficiency and has the problem of security hidden danger.

In order to solve the technical problem, the utility model provides a technical scheme does: a brake opening and closing booster of a molded case circuit breaker comprises an operating hand lever. The one end of operation handle bar is equipped with U type head, operation handle bar and U type head fixed connection, integrated into one piece, the other end of operation handle bar is equipped with the bulb, inside the operation handle bar stretched into the bulb, and can dismantle between the bulb and be connected. The U-shaped head adopts a U-shaped structure, so that the plastic shell circuit breaker operating handle is conveniently sleeved.

Further, the operating handle rod is provided with an external thread at one end close to the ball head, an internal thread matched with the operating handle rod is arranged inside the ball head, and the operating handle rod is detachably connected with the ball head through the matching of the external thread and the internal thread. The insulating plastic ball head can be detached, so that the insulating plastic ball head is convenient to maintain or replace.

Furthermore, the included angle between the operating handle rod and the horizontal plane is arranged in an acute angle structure. The arm force application of an operator is facilitated, the opening and closing speed is higher, and the operation efficiency is higher.

Furthermore, the bulb is made of insulating plastics, so that the potential electric shock hazard can be effectively avoided. The size of the insulating plastic ball head is matched with that of a human hand, so that an operator can hold the insulating plastic ball head with the hand conveniently, and the labor is saved.

Further, the U-shaped head is arranged in a structure with a wide upper part and a narrow lower part. The U-shaped cover is beneficial to covering the operation handle of the molded case circuit breaker, and the operation is simple.

Compared with the prior art, the utility model advantage lies in: the utility model effectively solves the problems existing in the prior art by using a switching-on and switching-off booster of the plastic case circuit breaker, and has the advantages of time and labor saving, high operating efficiency, good safety and the like; the utility model is provided with the U-shaped head, which can effectively facilitate the sheathing of the operation handle of the molded case circuit breaker and the opening and closing of the operator; meanwhile, the utility model is provided with the operating handle rod with the bent angle at the front end, which is beneficial for the operator to exert force on the arm, so that the opening and closing speed is faster and the operating efficiency is higher; in addition, the utility model discloses still be equipped with the insulating plastics bulb, can effectively avoid the hidden danger of electrocution, the security is high. The opening and closing operation is carried out by utilizing the opening and closing booster of the molded case circuit breaker, so that the condition that the circuit breaker cannot be opened or closed due to insufficient arm strength of an operator is avoided. Meanwhile, the situation that the front face of an operator faces equipment when the circuit breaker is forcibly opened and closed due to insufficient arm strength of the operator is avoided, the operator is hurt by accidents possibly, and the safe operation of a power grid is influenced is avoided. Therefore, the utility model provides a moulded case circuit breaker among the prior art be difficult for divide-shut brake, divide-shut brake inefficiency and have the problem of security hidden danger.
