Problems solved by technology

The disadvantage of this anti-shock structure is: since the circuit breaker is always locked when it is disconnected, if the closing button fails, the circuit breaker cannot be closed when it needs to be used, which will seriously affect the normal operation of the power system

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] The invention provides a buffer force unloading mechanism, such as figure 1 shown. The mechanism includes a stopper 1 , a limit shaft 2 , a return spring 3 , a pin shaft 4 , a balance pendulum 5 and a rotating shaft 6 . Peripheral equipment is circuit breaker main shaft 7 and bracket 8 .

[0023] The stopper 1 is welded together with the circuit breaker main shaft 7 through the arc-shaped structure at its upper end, and the lower end of the stopper 1 is a square structure. The limiting shaft 3 , the rotating shaft 6 and the pin shaft 4 are all fixed on the bracket 8 . The lower end of the balance pendulum 5 is flexibly connected with the rotating shaft 6 and can rotate around the rotating shaft 6 . One side of the balance pendulum is connected to the pin shaft 4 through a return spring 3 , and the other side is opposite to the stopper 1 . When ...

Abstract

The invention discloses a shock preventing mechanism having a buffering stress-alleviating function, which comprises a stopping piece, a balance, a limiting shaft, a return spring, a pin shaft and a rotating shaft, wherein the balance comprises a mandril, a rotating shaft, a compression spring and a clamping plate; and peripheral equipment includes a main shaft and a bracket of a circuit breaker. When the circuit breaker is shocked under the tripping state, the balance is turned below the stopping piece under the effect of a shocking force so as to hold the stopping piece and to further prevent the mistake contact of a circuit breaker contactor under the tripping state; after the shock, the balance can be returned to an initial position under the effect of the return spring, so normal closing of the circuit breaker is free from being influenced; and at the same time, when normal switching-on of the circuit breaker is required at the moment of strong shock, the balance can be pushed out by the stopping piece through the deformation of the balance, and the function of the circuit breaker can be prevented from being lost. Due to the adoption of the shock preventing mechanism, the circuit breaker can be safer and more reliable to use.

Description

technical field [0001] The invention relates to an anti-shock mechanism with the function of buffering and unloading force, which belongs to the field of marine electric appliances. Background technique [0002] The circuit breaker is mainly responsible for the protection of distribution lines and electrical equipment from overload, undervoltage and short circuit. The circuit breaker is closed or disconnected to achieve the purpose of power supply, power failure and conversion circuit. However, for marine circuit breakers, if subjected to strong shock and vibration, the circuit breaker in the open position may be closed instantaneously. Seriously affect the safety of operators and the normal operation of equipment, and even cause damage to the power system or cause a fire due to a short circuit in the system. [0003] The announcement number is "CN 100456412C", and the invention patent named "frame type circuit breaker anti-shock structure" adopts the scheme of locking the ...
