Abstract

The invention discloses an auxiliary device of a debug circuit breaker mechanism, comprising a framework, a downward static contact which fixedly connected with the framework in such a way that the position is adjustable and an upward movable contact which is matched with the downward static contact. The upward movable contact is in a T-shaped shaft shape, the upper end thereof is a free end with a larger section, and the lower of the free end is a rod part with a smaller section; the rod part of the upward movable contact is slidingly connected within a guide sleeve which is fixedly connected with the framework; a contact self-closing compression spring is clamped between the free end of the upward movable contact and the guide sleeve; and the lower end of the rod part of the upward movable contact is connected with an insulating pull rod through a connecting rod. The auxiliary device of the debug circuit breaker mechanism can simulate an explosion chamber of the circuit breaker, and can substitute the explosion chamber in the procedure of debugging the mechanical property of the circuit breaker, thereby avoiding the damage of the explosion chamber caused by the mechanical failure of the circuit breaker mechanism during debugging.

Description

technical field [0001] The invention relates to a debugging auxiliary device, in particular to an auxiliary device for debugging a circuit breaker mechanism. Background technique [0002] The circuit breaker is used to connect and break the circuit. It can not only connect and break the circuit under normal working condition, but also break the faulty circuit, the most serious of which is the short circuit. The circuit breaker consists of the following main parts: 1. Breakable contact connection. It consists of fixed contacts and movable contacts. 2. Devices consisting of insulating cylinders, in which breakable contact connections and arc extinguishing devices and transmissions are installed. 3. The transmission device that drives the contacts. 4. Arc extinguishing equipment. When a circuit breaker is commonly used to break a circuit, the moving contact of the circuit breaker is separated from the fixed contact by a mechanical method. When closing, the opposite mechani...
