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
