1. What is medium voltage electrical cabinet?
– Medium voltage electrical cabinet is designed and manufactured according to strict quality management process, has high stability, safety in operation and has been widely applied in power generation stations, power distribution stations of Power companies, industrial parks, residential areas and factories …. Currently, the medium voltage cabinet is an important electrical equipment for industrial, commercial and civil electrical construction.
– The structure of the cabinet ensures high safety: The cabinet is made of 2mm thick sheet of steel, firmly secured, and the switches such as the cutter are arranged properly and protected by an inner wing of the cabinet.
2. Structure of the medium voltage cabinet:
– Medium voltage electrical cabinet structure includes: Cabinet is made of about 2mm thick sheet, insulated, solid, and the switch is placed independently, reasonably and protected by an inner wing of cabinets.
– The cabinet includes equipment such as electrical panel up to 24KV and is used in the electricity industry, commercial buildings or in industrial plants.
3. Characteristics of medium voltage cabinets:
Below are some characteristics of the medium voltage switchboard
Manufactured according to IEC 62271-105 and IEC 60470 standards and rated voltage up to 12kV, indoor type, with 3 poles
Used for medium voltage motors, transformers and capacitors
Safe and reliable with fully sealed contactor housing and 2.5 bar low SF6 gas pressure.
Divided into separate and dedicated compartments for improved safety and continuous operation
There are types of MV contactor: there are 2 types of designs including fixed and removable
Contactor uses SF6 together with arc stamping technique – eddy arc technique – arc stamping and quick dielectric recovery, limiting the wear of contacts.
Electrical durability is enhanced by SF6 gas technology which reduces arc duration time and reduces arc elongation
Low switching ambient voltage prevents motor winding insulation canceling
Durable to external impacts, it can be used in the harshest environmental conditions such as mining, oil and gas
Can be combined with fuses to enhance protection.
4. How is the medium voltage cabinet used?
Medium voltage cabinets are used to switch off and protect medium voltage power supply lines. Medium voltage switchboards are often installed in power plants, transmission and distribution stations of power companies, or power distribution stations in industrial parks, residential areas.
