Basic technical conditions and characteristics of box-type substations
The box-type substation is used for AC 50Hz,10/0.4kV level voltage to transmit electrical energy and change the voltage.
Box-type substation should include:
1.All high-voltage power distribution devices in the box
2.All low-voltage power distribution devices in the box
3.Power transformer(2 SC-50 dry-type hermetically sealed transformers)
4.Spare parts,spare parts
5.Other related facilities and components in the box
Box-type substation standards:
(1)GB/T 17467-1988 high-voltage/low-voltage prefabricated substation
(2)ZBK40001 combined substation
(3)Technical conditions of SD320 box-type substation
(4)Rated voltage of GB156 electrical equipment
(5)GB 311-1997 Insulation coordination of high voltage power transmission and transformation equipment
(6)GB763 AC high-voltage electrical appliances generate heat during long-term work
(7)DL/T537 6~35kV box-type substation order technical conditions
(8)GB/T 11022-1999 common technical requirements for high voltage switchgear and control equipment standards
