1. Product Introduction of The GZDW Series DC Power Supply
GZDW series DC power supply system is mainly composed of intelligent high-frequency switching power supply module, central monitoring unit, maintenance free battery and feed circuit. It has many advantages such as light weight, small volume, high efficiency, no pollution, high degree of intelligence, convenient operation and maintenance. Moreover it's high reliability. It is an ideal replacement product for the complete set of traditional DC power supply.
GZDW series products are mainly used in small and medium-sized power plants, hydropower stations, various substations, switching stations and other users using DC equipment in power system (such as petrochemical, mining, railway, communication, building materials, metallurgy, high-rise buildings, etc.).
They are important equipment to ensure the safe operation of power grid and power plant, For all kinds of circuit breakers (electromagnetic operation type, spring energy storage type) to provide opening and closing power supply, As well as provide DC power supply to the secondary loop instrument, control loop, relay protection and accident lighting and other types of high and low voltage equipment to provide dc power supply. Especially in the event of a failure, it is the standby power supply for various control devices and protection devices in the whole substation, and plays a very important role in the whole substation and distribution automation system.
