Purpose of rectifier cabinet
The rectifier cabinet is divided into two types: ground and underground
It is mainly used for DC power supply of mine traction locomotive, urban trolley bus, subway and other traction substations

The rectifier cabinet adopts three-phase bridge rectifier circuit, and its rectifier transformer has ± 5% rated voltage tap, changing the wiring can change the AC input voltage ± 5%。
The locomotive rectifier cabinet adopts automatic air circuit breaker, over-current relay and thermal relay for over-current and phase short-circuit protection, the three-phase at AC side is equipped with lightning arrester for lightning protection, and the tributary adopts resistance capacitance absorption device for over-voltage protection

This series of products are divided into thyristor and silicon rectifier
Thyristor rectifier has the functions of automatic voltage stabilization, current stabilization and overcurrent cut-off tripping

Rectifier transformers are generally dry-type, epoxy resin casting type and oil immersed type
