Switchgear is one of the most basic and common equipment in high-voltage distribution rooms, mainly used for controlling and distributing power supply. Common switchgear includes vacuum circuit breakers, load switches, isolating switches, grounding switches, etc. Among them, vacuum circuit breakers are one of the most important switchgear devices, responsible for quickly cutting off the power supply in case of circuit failure, ensuring the safety of the power system.
2. Transformer
The transformer is another important equipment in the high-voltage distribution room. Its role is to transform the high-voltage power supply into low-voltage power supply to meet the power demand of different occasions. There are many types of transformers, such as dry-type transformers, oil-immersed transformers, reactors, isolation transformers, etc. Different types of transformers have different characteristics and can be selected according to actual needs.
3. Power cable
Cable is another important power transmission equipment in high-voltage distribution rooms, which is used to transmit electricity from the high-voltage distribution room to distant consumer terminals. Cables are divided into different types and specifications, such as polyethylene insulated cables, cross-linked polyethylene insulated cables, rubber insulated cables, etc., and are selected according to the usage environment and needs.
4. Cable accessories
Cable accessories refer to equipment used in conjunction with cables, such as terminals, connectors, lead clamps, etc. These devices play a crucial role in ensuring the stability and reliability of power transmission.
In summary, there are various types of equipment in high-voltage distribution rooms, including but not limited to switchgear, transformers, cables, and their accessories. These devices play an important role in the transmission, control, and distribution of electricity, and are indispensable components of the power system.
