Abstract

This paper introduces the architecture and implement method of a mine explode isolation HV (high voltage) switch digital integrated protective system on DSP+CPLD. The electric quantity measuring principle, the CPLD feedback control principle for the relay protection tripping and closing control circuitry and the implementation principle of the overcurrent reversing time limit digital protection are described in detail. And the technical development prospects for the explode isolation HV switch digital integrated protective system are briefly given.
