Problems solved by technology
The circuit breaker fixed on the chassis is a moving part relative to the cabinet. Due to design or assembly reasons, it may not be able to achieve complete alignment when the dynamic and static contacts are engaged, which will cause contact between the dynamic and static contacts. Resistance, thus causing partial discharge or local overheating of the moving and static contact engaging parts, the lighter ones will cause the switch to burn out, and the severer ones will cause the switch to burst, seriously endangering the safety of the power grid

Embodiment Construction
[0020] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as Figures 1 to 3 As shown, an on-line detection device for centering and matching of moving and static contacts of a switch cabinet may include a circuit board 1, a sensor 2, and a concave-convex matching structure, wherein the concave-convex matching structure includes a concave cavity and a protrusion, and the concave cavity and the convex The risers are respectively installed on the side of the static contact and the side of the moving contact, and vice versa; the circuit board 1 is electrically connected to the sensor 2 for online detection of whether the concave cavity and the protrusion are centered and engaged. The sensor 2 can be installed on one side of the concave cavity or on the side of the convex cavity. When the chassis car swings the circuit breaker in, if the concave cavity and the protrusion are aligned, the sensor 2 w...

The invention relates to an online detection device for centering matching of moving and static contacts of a switch cabinet. The static contact is fixed on a switch cabinet body, the moving contact is fixed on a circuit breaker, the device can comprise a circuit board, a sensor and a concave-convex matching structure, the concave-convex matching structure comprises a concave cavity and a bulge, the concave cavity and the bulge are respectively arranged on a static contact side and a moving contact side, and vice versa; and the circuit board is electrically connected with the sensor and is used for detecting whether the concave cavity and the bulge are centered and engaged or not on line. According to the invention, on-line detection of centering cooperation of the moving and static contacts of the switch cabinet can be realized without modifying primary components of a circuit breaker, complete centering of the moving and static contacts is ensured, and the online detection device issuitable for newly installed switch cabinets and old switch cabinet reconstruction projects.
Description
technical field [0001] The invention relates to the field of switch cabinets, in particular to an on-line detection device for centering and matching of dynamic and static contacts of a switch cabinet. Background technique [0002] The withdrawable circuit breaker of the switch cabinet has the following structure: the static contact is fixed on the switch cabinet body, the moving contact is fixed on the circuit breaker, the circuit breaker is fixed on the chassis, and the moving and static contacts are completed by shaking into the chassis. meshing fit. The circuit breaker fixed on the chassis is a moving part relative to the cabinet. Due to design or assembly reasons, it may not be able to achieve complete alignment when the dynamic and static contacts are engaged, which will cause contact between the dynamic and static contacts. Resistance, thus causing partial discharge or local overheating of the engaging parts of the moving and static contacts. In the light case, the s...
