The invention, which belongs to the technical field of low-voltage circuit breaker controlling, discloses a simple-and-rapid-relay-switching type intelligent control module for opening and closing of a permanent-magnetic circuit breaker. The intelligent control module is composed of a main loop, a microprocessor, a relay change-over switch drive circuit, a closing capacitor voltage detection circuit, and a closing capacitor voltage detection circuit. Because opening and closing are controlled by using one power switch and the driving circuit thereof, the number of elements of the control circuit is reduced and thus the circuit structure is simplified, so that miniature development of the permanent-magnetic circuit breaker can be realized well. Moreover, the overall size of the permanent-magnetic circuit breaker is reduced and controllability of the circuit breaker is improved.
Description
technical field [0001] The invention discloses an intelligent control module for opening and closing of a permanent magnet circuit breaker with a simple and fast switching type of a relay, and belongs to the technical field of low-voltage circuit breaker control. Background technique [0002] As an important switching electrical equipment in the power system, the circuit breaker mainly plays the role of connecting and breaking the normal line and quickly cutting off the faulty line in the power supply and distribution system. The permanent magnet circuit breaker has a simple structure, fast opening and closing speed, The advantages of maintenance-free, high reliability and easy control have been widely used in power system automation, and its control performance is directly related to the safe, stable and reliable operation of the smart grid. As an important part of the permanent magnet circuit breaker, the intelligent control module part, its working performance directly af...
