Low Voltage Integrated Distribution Board

The low voltage integrated distribution box is a distribution device suitable for three-phase AC 50HZ, rated voltage 0.4KV power applications. It provides real-time monitoring and analysis for distribution transformer operation data and a fault protection system in order to prevent transformer district line loss. The distribution device also features a comprehensive meter reading system, automatic compensator for reactive power and wireless data transmission.

The integrated distribution box completes automatic management for distribution networks using economic, safe, and reliable running schemes, laying a good foundation for the formation of a properly running and highly efficient power grid and for the deployment of an integrated automatic power system. This improves the service quality of the power distribution system and minimizes external management input investment of power supply enterprises.

The low voltage integrated distribution board is a device used for power distribution, monitoring, and control in power systems, typically used in industrial, commercial, and residential buildings. Low voltage integrated distribution boxes commonly include components such as incoming switches, circuit breakers, fuses, current transformers, energy meters, controllers, and relays.

Application

The low voltage integrated distribution box can carry out automatic tracking and compensating for low-voltage power distribution transformers and all kinds of electric power user overloading operations by increasing the distribution capacity to 15%-30%. Meanwhile, the box will reduce potential damage caused by overloading by 25%-50%. The box improves the quality of voltage, reduces the power consumption, and makes full use of electrical energy. The box is widely used in city and rural power grid construction and renovation projects.

Features

Flexibility: The configuration of the distribution box can be customized according to actual needs, meeting the power distribution requirements of different places and demands.

Safety: The distribution box has good protective performance to ensure the safety of equipment and personnel. It also has overload protection and short-circuit protection functions, improving the safety performance of the equipment.

Maintainability: The internal structure of the distribution box is reasonably designed with a clear layout, making it easy to maintain and manage, reducing maintenance and repair costs and workload.
