8 pairs of limit 6.3KV of transformer are connected to totally-enclosed low pressure made of iron room 29, are divided into 2 loops, and a loop 6.3KV is for load, and another loop is for the transformer 19 of 6.3KV/0.4KV, as the operation control of this equipment, illumination, electric fan electricity consumption.Its output line 6.3KV adopts the high-tension cable outlet; 0.4KV adopt the low-voltage cable outlet; current transformer 13, ammeter 14, voltage transformer 15 are housed in low pressure room 29; voltmeter 16 is as current/voltage indication and measurement; ground measuring tester 27 is as high pressure electric leakage supervision, overcurrent protection and supervision; lightning arrester 7 is as discharge prevention, and isolating switch handle 18 is installed in 29 outsides, low pressure room, can manually control.

Transformer 8 is to adopt S9 type transformer; high-pressure side wiring pipeline 11, low-pressure end wiring pipeline 12, transformer 8 and high pressure room 28, low pressure room 29 are coupled together; high voltage input terminal 9; low pressure input terminal 10; be enclosed in respectively in the high-low

pressure termination spool

11,12; transformer 8 both sides are furnished with fin 43; 3 road stiffener bands 44 are arranged around the transformer 8; stress protection as oil pressure in the transformer has oil pressure gauge 38, oil level gauge 39 above; this does not establish conservator above transformer; replace with pressure relief valve 40, protection device 41 has fluid drain valve 42 below.

The base of this mobile substation adopts the totally-enclosed sled base 32 of steel construction, and the base bottom has upper sealing plate 36 is arranged on the slide plate 34, has following shrouding 37, centre that reinforcement 35 is arranged down, and the every side in two ends has 2 traction draw rings 33, draws and opens and hang use as short distance.

High pressure room 28, low pressure room 29 adopt sheet iron to make, and be integrally welded with base 32.Outdoor when indicator light 26 being housed disconnecting as circuit breaker 5 indicator light send danger signal indication, the indoor illuminating lamp 25 that is equipped with.

Important technological parameters:

1, input rated voltage 35KV, rated current 10A;

2, output rated voltage 6.3KV;

3, lighting transformer input and output rated voltage 6.3KV/0.4KV;

4, base length * wide=9500mm * 2200mm.
