A circuit breaker detection device

Abstract

The invention provides a breaker detection apparatus. The breaker detection apparatus comprises an apparatus frame, contact bodies and insulation pull bars. The contact bodies comprise static contacts and moving contacts which are adapted to each other. The static contacts are fixedly arranged on the apparatus frame, the moving contacts are in opposite arrangement with the static contacts and are fixedly arranged on the apparatus frame through the insulation pull bars, and the moving contacts can be driven by the insulation pull bars to perform elevating movement. The contact bodies are provided with pressure sensors. According to the invention, through simulating opening and closing motion of the breaker contacts, under the condition that whether a breaker can be used normally and the clearance between open contacts is obtained easily, pressure values of the contacts are accurately obtained, guidance is provided for debugging and installing poles of the breaker, and the debugging installation efficiency of the breaker is substantially improved.

Description

technical field [0001] The invention relates to power distribution equipment, in particular to a circuit breaker detection device. Background technique [0002] As the core component of the high-voltage switchgear, the high-voltage AC vacuum circuit breaker mainly plays the role of breaking and closing the distribution line during the working process of the switchgear. It determines this key performance in addition to the opening speed and closing speed of the circuit breaker. In addition to the conditions, there are two important indicators: the contact pressure and the opening distance of the vacuum switch tube. [0003] At present, the contact pressure of high-voltage AC vacuum circuit breakers is generally adjusted and estimated based on the linear relationship of the spring and assembly experience, and there is no direct and effective detection method; although the opening distance of the contacts can be measured in the later detection of mechanical characteristics, but...

Problems solved by technology

[0005] The above scheme is only to simulate the arc extinguishing chamber of the circuit breaker, which is used to detect whether the circuit breaker can work normally after the pole is installed, but the contact pressure value on the pole cannot be detected more accurately during the working process of the circuit breaker Obtained, unable to meet the detection of important performance indicators of circuit breakers
