Abstract

The present invention relates to a contact point monitoring module for a vacuum circuit breaker and a vacuum circuit breaker comprising the same. The present invention provides a vacuum circuit breaker comprising a push rod assembly which is coupled to a movable electrode of a vacuum interrupter and moves the movable electrode up or down to make a movable contact in a contact closed state or a contact open state, wherein the vacuum circuit breaker comprises a linear sensor which is coupled to a lower side of the push rod assembly and senses displacement according to a moving direction of the push rod; and a sensor holder which is installed adjacent to the lower side of the push rod assembly and is coupled to the linear sensor to process a signal transferred from the linear sensor.

Description

technical field [0001] The invention relates to a contact monitoring module device for a vacuum circuit breaker capable of monitoring the amount of contact wear inside a vacuum interrupter and a vacuum circuit breaker with the device. Background technique [0002] A vacuum circuit breaker is an electrical protector that utilizes the dielectric strength of a vacuum to protect load equipment and lines from fault current when a fault such as open circuit or grounding occurs in the circuit. [0003] Vacuum circuit breakers are used for power transmission control and protection of power systems. The breaking capacity of the vacuum circuit breaker is large, and the reliability and stability are high. In addition, since the vacuum circuit breaker can also be installed in a small installation space, its application range is extended from medium voltage to high voltage. [0004] The vacuum circuit breaker includes a vacuum interrupter as the core component of cutting current, a pow...
