The invention discloses a reset locking mechanism of a circuit breaker, which relates to the technical field of circuit breakers. Aiming at the problem of preventing the circuit breaker from being reset after it is disconnected, the following proposal is proposed, including a housing, and a first horizontal plate and a second horizontal plate are arranged inside the housing. Two horizontal plates, the inside of the housing is provided with a worm wheel, and a first worm is provided below the worm wheel. A sleeve is sleeved at both ends of the first worm, and a support rod is movably connected to the sleeve. The top end of the support rod A half gear is welded, and a rack is arranged above the half gear. In the present invention, through the combination of various structures, after the circuit breaker trips, the maintenance personnel will hold the switch against the switch when maintaining the device or the circuit, so as to prevent others from resetting the switch without knowing it. It not only guarantees the damage of the equipment, but also protects the life and health of the maintenance personnel. This device replaces the padlock method with the locking of the knife switch, which is convenient for the staff to reset the circuit breaker after maintenance, saves time and improves work efficiency.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker reset locking mechanism. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The circuit breaker is generally used at the front end of the power supply line, and has a large capacitance. After the circuit breaks down and trips, it is easy for non-professionals or people with unknown reasons to close the switch by mistake and cause personnel or equipment losses. [0003] In the prior art, the prevention of false closing is mainly to set signs, padlocks and other methods, but these methods are complicated to operate in the process of s...
