Elementary introduction of component structure and voltage grade of box type substation
Box type transformer substation, also known as box transformer, pre installed substation, etc。, is divided into American box change and European box change。
The electrical and equipment components in the box type substations are all finalized products, and the technical performance of the components meet the corresponding standard requirements. The box type substations also have the functions of electric energy detection, display and metering, and can realize corresponding protection functions. They also have special earthing guides and obvious grounding signs.
Guizhou is on the box type substation is suitable for outdoor working environment, the top box shell is generally used inside the interlayer structure, insulation materials, a cooling air inlet and outlet of each chamber and between the bottom of the box, using natural air cooling and automatic control of forced air cooling and other forms, in order to ensure the normal cooling of electrical equipment, has rainproof, dustproof, to prevent a small animal into other measures
At present, the voltage grade of box type change in domestic production is 3 ~ 35kV in high voltage side and 0.4 to 10kV in low pressure side. The capacity of the transformer, when the rated voltage is 35/10, 6, 0.4 kV from several hundred KVA to 10000 KVA, when rated voltage ratio is 10, 6/0.4 kV from tens to several thousand volt ampere.
