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.

Low voltage switchgear and low voltage distribution cabinet are two common devices in the power system, which have certain differences in function and structure.

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.

Low voltage distribution cabinet: refers to a power device that integrates various components such as transformers, switchgear, fuses, capacitors, and energy meters. Its main function is to distribute the high voltage power transmitted through a transformer after voltage reduction to the low voltage electrical load, while protecting and monitoring the circuit. Low voltage distribution cabinets are usually installed in large industrial and mining enterprises, hospitals, commercial centers, and other places to provide stable power supply for various electrical loads.

 

Simply put, low-voltage switchgear is mainly used for controlling and protecting circuits, while low-voltage distribution cabinets are mainly used for distributing electrical energy. There are also some structural differences between the two. Low voltage switchgear is usually composed of one or more closed partition boxes, in which components such as switchgear and wiring terminals are installed; The low-voltage distribution cabinet adopts a combination design, which can be flexibly assembled according to needs. The box contains different functional modules such as transformers, fuses, capacitors, etc.

In short, low-voltage switchgear and low-voltage distribution cabinets are important components of the power system. Although their functions are slightly different, they both play an important role in ensuring the stable operation of the electrical system. When choosing to use, it should be judged based on actual needs and configured reasonably according to their respective characteristics
