Summary
BSDFK series intelligent compound switch is a new generation of electronic products (hereinafter referred to as compound switch), which is divided into two types: co-compensation type and sub-compensation type. The co-compensation type is used to switch three-phase capacitors and adopts delta connection method. The sub-compensation type is used for switching single-phase capacitors, and Y-connection is adopted. The biggest advantage of the new generation compound switch is the combination of software and hardware by using single chip microcomputer technology. When working, according to the phase sequence characteristics of three-phase electricity and the phase of each phase, the single chip microcomputer is used to switch each phase of the capacitor respectively, thus realizing the switching process of parallel capacitors without inrush current and overvoltage. Compound switch has obvious advantages such as no impact, low power consumption, long service life and low fault, which can replace AC contactor and capacitive contactless switch and is widely used in the field of low-voltage reactive power compensation.
