Description

Double unit movable substation

Two cell moving transformer station belongs to a kind of power supply power supply unit, is mainly used in the field construction scene, as building of highway, railway and bridge, and opencast mining, oil field, constructing tunnel place etc.

At present domesticly normally adopt fixedly transformer station for high voltage variable, distribution, this fixedly transformer station cost is higher, can not satisfy the needs that interim unit in charge of construction uses again, after engineering is finished, also will remove fixedly converting equipment and building, cause great waste.

The purpose of this utility model is in order to satisfy the needs of field construction place such as highway, railway, bridge, constructing tunnel, a kind of pair of cell moving transformer station is provided, this transformer station can be contained on train or the automobile and to do long-distance transport and move, or is drawn to new construction site with the tractor short distance.

Two cell moving transformer station is that this transformer station is made up of high pressure wire inlet unit and low-voltage distribution unit to the existing fixedly improvement of transformer station, and this mobile substation has fully closed and semi-enclosed two kinds.Totally enclosed type as shown in Figure 1 it the high pressure wire inlet unit and low-voltage distribution unit all be fixed on steel construction sled base 27 on, high pressure room 23, low pressure room 24 all adopt sheet iron to make iron room and base 27 is integrally welded.Its mesohigh wire inlet unit comprises: be installed in the folding high tension terminal 1 on the high pressure room 23, be contained in the high pressure inlet wire insulator 2 on this binding post, high pressure wall conduit tube 3, high-tension fuse 4 is housed in high pressure room 23, vacuum circuit-breaker 5, lightning arrester 6, transformer 7, high voltage input terminal 8 is arranged on transformer 7, have fin 11, bottom that fluid drain valve 12 is arranged around low-voltage output 9, conservator 10, the transformer.Low-voltage distribution unit comprises: low pressure room 24; isolating switch 13 is housed in low pressure room 24; divide into 3-8 loop load; all there is on-load switch 18 in each loop, and fusible link 19 control protections have current transformer 14 in low pressure room 24; ammeter 15, voltage transformer 16, voltmeter 17; as the indication of current/voltage, electric leakage monitors overcurrent protection and supervision to earthing test monitor 22 as high pressure.

Be provided with traction draw ring 28 in the every side in sled base 27 two ends, draw and open and hang use as short distance, upper sealing plate 30 is arranged at base 27 tops, and following shrouding 31 is arranged at the bottom, and reinforcement 32 is equipped with in the centre.Slide plate 29 is arranged at the base bottom; As shown in Figure 2 semienclosed, its high pressure wire inlet unit comprises folding high tension terminal 1, dress high pressure inlet wire insulator 2 thereon, high-tension fuse 4, vacuum circuit-breaker 5, lightning arrester 6, transformer 7 critical pieces are formed, this unit is powered by high-tension cable by the 10KV electrical network, and low-voltage output 9 through 7 pairs of limits of transformer is powered to low pressure room 24 power supply units, for guaranteeing safety, be provided with guardrail purse seine 33 all around.

Important technological parameters:

10KV/0.4KV transformer station

1, input rated voltage 10KV;

2, output rated voltage 0.4KV;

3, transformer capacity is 500～800KVA;

4, base is long, and wide is 500mm * 2200mm;

6KV/0.4KV transformer station

1, input rated voltage is 6KV;

2, output rated voltage is 0.4KV;

3, the transformer rated capacity is 300～500KVA;

4, the base length and width is 5500mm * 2200mm.

When if the voltage of change input electrical network is 6KV, only needing to change transformer 7 be 6KV/0.4KV, and capacity is 300～500KVA, promptly becomes the transformer station of 6KV/0.4KV.
