What are the differences and application scope between low-voltage distribution cabinets and high-voltage distribution cabinets?

low pressurePower distribution cabinetHigh-voltage distribution cabinets and high-voltage distribution cabinets are two common types of power distribution equipment in power systems. They have some obvious differences and their respective application ranges.

First of all, low-voltage power distribution cabinets refer to power distribution equipment with a rated operating voltage not exceeding 1000V. They are generally used in power distribution systems in factories, commercial buildings, residences and other places. Low-voltage power distribution cabinets mainly play the role of distributing the total power to different subsystems or equipment, and protecting and controlling electrical equipment. Low-voltage power distribution cabinets usually use AC as the input power supply, have lower safety requirements and costs, and are suitable for places that require smaller voltages.

High-voltage power distribution cabinets refer to power distribution equipment with a rated operating voltage above 1kV. They are generally used in booster stations,substation, large industrial enterprises and other places. High-voltage power distribution cabinets are mainly used to distribute the high-voltage power output from the substation to various users or equipment to achieve long-distance transmission and supply of power. High-voltage power distribution cabinets use DC or AC as input power, have stricter safety requirements and more complex technical requirements, and are suitable for places that require high-voltage power transmission.

Generally speaking, low-voltage distribution cabinets are suitable for industrial, commercial and residential places where safety requirements are not high, and are mainly used for power distribution and control of general power supply, lighting, sockets, motors and other circuits; while high-voltage distribution cabinets are suitable for In large power systems that require long-distance transmission and power supply, it is mainly used for voltage boosting, distribution and control of high-voltage power grids.

Generally speaking, there are obvious differences between low-voltage distribution cabinets and high-voltage distribution cabinets in terms of use, voltage, etc., and each has its own application range in different places. In practical applications, it is necessary to select appropriate power distribution equipment according to the specific site and electrical system requirements to ensure the safe and reliable operation of the power system.
