What is a gas insulated switchgear?

Gas Insulated Switchgear (GIS) is a metal-enclosed switchgear that uses high-insulation gas (such as sulfur hexafluoride SF₆) as an insulating and arc-extinguishing medium. Compared with traditional air-insulated switchgear (AIS), gas-insulated switchgear has the advantages of compact structure, safety and reliability, and strong environmental adaptability, and is widely used in medium and high voltage power systems.   Jutai Platform XGN15 series gas-insulated switchgear is a metal-enclosed...

How many kW of power consumption can a 1000kVA transformer handle?

"There is an old transformer with a capacity of 1000kVA. The current load is about 200kW. If a new load of about 600kW is to be added, can this transformer withstand it?" This question first involves a concept, that is, the relationship and difference between kVA and kW. kVA (kilovolt-ampere) is the unit of apparent power, and kW (kilowatt) is the unit of active power. In addition to apparent power and active power, there is also reactive power, and the unit of reactive power is kvar (kilovar)....

A complete explanation of transformer main protection and backup protection knowledge

Transformers are static equipment that runs continuously, and their operation is relatively reliable with fewer chances of failure. However, since most transformers are installed outdoors and are affected by the load they bear during operation and the short-circuit faults of the power system, various faults and abnormalities are inevitable during operation. 1. Common faults and abnormalities of transformers Transformer faults can be divided into internal faults and external faults. Internal...
