Problems solved by technology
[0002] The existing intelligent integrated high-voltage contactor controllers mainly have the defects of poor anti-strong electromagnetic interference ability and poor control precision of the switch mechanism. The former leads to a decline in the overall reliability of the intelligent integrated high-voltage contactor, which is likely to cause grid safety accidents and equipment damage accidents; The latter leads to slow opening and closing control speed and poor precision, and cannot realize the ideal "zero switching" and the requirement of no bouncing in the opening and closing process. The overall function is not complete, and more equipment is required in the actual process.

A controller of an intelligent integrated high-voltage alternating current contactor comprises a controller body 1, a front end circuit 2 and a mechanical movement stroke detection circuit 3, wherein the controller body 1 is embedded inside a contactor body, the front end circuit 2 is installed a safe position where man-machine connection is convenient, and the mechanical movement stroke detection circuit 3 is installed in a position where the movement of a movable contact inside a contactor switch tube can be detected. The controller suitable for the intelligent integrated high-voltage alternating current contactor has the advantages of being high in intelligence degree, complete in function, simple and reasonable in structure, reliable in operation, good in maintenance performance and high in performance cost ratio.
Description
technical field [0001] The invention relates to the field of high-voltage contactor controllers, in particular to a high-voltage contactor controller capable of realizing intelligent integration. Background technique [0002] The existing intelligent integrated high-voltage contactor controllers mainly have the defects of poor anti-strong electromagnetic interference ability and poor control precision of the switch mechanism. The former leads to a decline in the overall reliability of the intelligent integrated high-voltage contactor, which is likely to cause grid safety accidents and equipment damage accidents; The latter leads to slow opening and closing control speed and poor precision, and cannot realize the ideal "zero switching" and no bouncing requirements in the opening and closing process. The overall function is not complete, and more equipment is needed in the actual process. Contents of the invention [0003] The technical problem to be solved by the present in...
