Description
1. Application
The type of transformers are applicable to 35KV and below, the small unattended substation, with main interior capacity of 5000KVA and below, is widely used in urban industrial substation, 10KV switch stations, ring network system, rural power grid 35KV substation and other occasions.
2. Main Function
To complete the conversion, distribution, transmission, measuring, compensation and the system control of the electrical energy, meanwhile, realizing the functions of protection and communication.
3. Main Characters
The preliminary and secondary equipments are pre-installed in the cabinet which is removable, whole-sealed, temperature automatic controlled, antiseptic, damp proof and rustproof, it only needs to be installed on the cement basis after arriving at the scene.
This kind of transformers have the advantages of low investment, short construction period, small floor space and easy
environmental coordination.
4. Notes to the ordering of the Europe Prefabricated Substation
1. High voltage
Way of incoming line: terminal type, looped network type or double power in.
With the high pressure measurement or not. The position of the measurement(front of the switch or behind the switch), the requirement of the meter gauge and its supplier.
Type of the HV switch, one way is using the high voltage vacuum load switch and the fuse-combination unit which is the mainly used and its price is more economical; the other is adopting the disconnector switch and the vacuum breaker which is used in the high capacity transformer with higher price.
2. Transformer
the transformer type, serial-number, the connection symbol group, capacity and the impedance voltage of the transformer.
3. Low voltage
Switch Supplier. The number of the outgoing ways and the rated current value of each outgoing switch. Whether there is the compensation or not, if yes, the capacity of the compensation. Whether with the metering or not. If yes, the position is necessary.
4. Type of the busbar (copper or aluminum)
5. Layout of the transformer substation(with the operation corridor or not)
6. The material of transformer shell: composite board (commonly used), steel plate, stainless board or cement.
