Technical Field

The invention relates to the technical field of high-voltage substations, in particular to safety protection equipment for a high-voltage substation.

Background

The transformer substation is a place for converting voltage and current, receiving electric energy and distributing the electric energy in an electric power system; the transformer substation in the power plant is a boosting transformer substation, and the function of the boosting transformer substation is to boost the electric energy generated by the generator and feed the boosted electric energy into a high-voltage power grid; the most common of high voltage substations is the high voltage switchgear.

The electrical equipment in the transformer substation is divided into primary equipment and secondary equipment:

1. disposable device

The primary equipment refers to equipment for directly producing, conveying, distributing and using electric energy, and mainly comprises a transformer, a high-voltage circuit breaker, an isolating switch, a mutual inductor (a current mutual inductor and a voltage mutual inductor), a bus, a lightning arrester, a lightning rod, a capacitor, a reactor and the like.

2. Secondary equipment
