LV GZD Power Switchgear 100A Distribution Cabinet
Low voltage switchgear: refers to the box body equipped with switchgear such as circuit breakers, isolation switches, load switches, grounding switches, etc. Mainly used in distribution systems to introduce power and control the distribution of current to various loads to ensure the normal operation of the power grid. The main function of low-voltage switchgear is to protect, control, and monitor the circuit to ensure the normal operation of the circuit and the safety of the electrical load. Low voltage switchgear is usually installed in substations, factories, commercial buildings, and other places, and is an important component of the electrical system
Description
LV GZD Power switchgear 100A distribution Cabinet
GZD panel power supply cabinet is suitable for substations, power plants, industrial and mining enterprises, electrified railways and high-rise buildings of different voltage levels. It can be used as operating power and control power for high-voltage switches, relay protection and automatic devices. The system adopts the integrated design idea and consists of monitoring module, rectifier module, insulation monitoring module, battery inspection module, switch monitoring module and step-down module. It has advanced technology, reasonable configuration, intelligent measurement and control, and easy operation. It can communicate with the host computer and conveniently realize the four teleoperation functions of “telemetry, remote control, remote signaling and remote adjustment”. It is an ideal DC power supply device for unattended operation.
Description of GZD DC Power Supply Panel

Feature
Intelligent dual-power switching: There is double AC power input way for the panel. One is the way for working power; another is the way for standby power. When the power fails, the system automatically switches to standby power.
Automatic voltage converter: The panel automatically converts voltage value according to voltage of closing bus-bar. The panel uses a pressure relief device-level or pressure relief device. This work is stable and reliable.
Multi-protection design: The panel has surge protectors which prevent over-voltage of the power supply. There are overvoltage protection, current limiting protection, short- circuit protection, module parallel protection, over-temperature protection and over-current protection system as a whole can improve the safe and reliable operation.
N +1 redundancy design: The charging module has N + 1 to improve reliability, the charging module has self cooling, supports live hot plugging-in and pulling, is easy to maintain.
Centralized Monitoring Function: Coordinate with the central monitoring or control of the DC power supply components and operating parameters of the role of the state, at the same time concentrate on each module Parameters upward crew transmission, PC and transmitted under the order. Use of the structural design of building blocks, can lose control Level. All AC voltage, current, spare each other automatically switching; coordination or control supply bus-bar of current, voltage parameters. Battery voltage parameters, battery charge and discharge current parameters; system insulation parameters; reclosing switch monitoring, control switches, batteries Melting Off work for the state of insulation fed a control loop (optional); Patrol battery (optional), monitor the environment temperature.
