HCFK series intelligent electronic capacitor switching switches are new-generation electronic products (hereinafter referred to as composite switches, which are divided into co-compensation type and sub-complement type. Co-compensation type is used for switching three-phase capacitors, using 4 connection method; The complementary type is used for switching single-phase capacitors, and uses a V-type connection. The advantages of the new-generation composite switch use single-chip technology, which is a combination of software and hardware. According to the phase sequence characteristics of three-phase electricity, it works in several AC cycles during operation. According to the phase of each phase, the single-chip microcomputer is used to switch each phase of the capacitor, so as to realize the switching process of the parallel capacitor without inrush current and without overvoltage. The composite switch has no impact, low power consumption, long life, low failure With obvious advantages, it can replace AC contactors and capacitive contactless switches, and is widely used in the field of low-voltage reactive power compensation.
