Abstract

The invention provides an intelligent protection system. The system comprises a core processing unit, wherein the core processing unit is respectively connected with an intelligent reactor protection device, an intelligent motor protection device, an intelligent transformer protection device, an intelligent capacitor protection device and an intelligent line protection device. The system realizes the switching of different protection devices by performing simple operation through an operation interface so as to realize three-sectional direction over-current protection, inverse time-lag over-current protection, zero-sequence current protection, negative phase sequence protection, over-voltage protection, under-voltage protection, zero-sequence voltage protection, over-heat protection, and reclosing and post acceleration protection of various types of electric equipment. Therefore, more and more comprehensive protection can be provided for the electric equipment.

Description

technical field [0001] The invention relates to the technical field of electronic and electrical equipment, in particular to an intelligent protection system. Background technique [0002] The protection devices provided by the prior art are individually corresponding to various electrical equipment, and provide various protections for various electrical equipment, but the hardware platform provided by the prior art has slow running speed and small storage space, and cannot realize the integration of various protection functions. .
