Tunnel 380v Power System Construction Plan

1. Tunnel construction wɛ̈t

Tunnel construction is usually first hole drop slope, then cut water trench construction, hole ahead of large pipe shed, large pipe shed injection, drilling, dropping drugs, blasting, excavator discharge, debris, supplementary artillery, initial support, arch or underfloor, drainage board, geotechnical clothing, waterproof board, two lining, trench cable slot, bottom plate.

II. Tunnel Construction Electrical Equipment Introduction

Tunnel hole air compressor, tunnel hole air compressor, tunnel hole lighting, tunnel hole drilling, requires large power large amount of air compressor, such as Atlas air compressor, Sanyi heavy industry air compressor, XCMG air compressor, Kaishan air compressor, five ring air compressor etc. in the construction site often seen, two lining construction spray machine such as Atlas cement ground spray machine, CNC can move rock excavator etc., conveying pump, tunnel water pump, if there is a support period with wire welding machines, the hole in general construction will not exceed 150KW of electrical equipment, hole hole equipment 200kW, cement dump plant power is about 400KW, there are also some construction sites using tunnel excavator, shield, TBM and other large equipment, over 1000KW. load will be greater.

4. Tunnel Construction Electric System Traditional Solutions

Soldiers don't move grain and grass first, as the foundation guarantee of tunnel engineering - power supply, but if the power system doesn't give power, difficult construction won't be able to talk about, we as many years tunnel construction power system support equipment suppliers, summarizing the experience as follows, in the 500 m within the power system, small equipment has no need to be modified can basically satisfy construction, if more than 500 m using 10KV high voltage electrical inlet hole costs too high, and more than 1000 m using diesel power generation equipment, costs can't be underestimated.

2、Tunnel hole construction site multi-distance hole transformer remote voltage low

3, tunnel hole construction site multi-line remote equipment start current large instant pressure drops, so that the equipment can't start. 3, tunnel hole construction site multi-line remote equipment start current large instant pressure drops large instant, so that the equipment can't start.

4.Tunnel tunnel in the tunnel hole is longer than 2500 meters and does not want to use 10KV high voltage

3, (suitable for high precision equipment) adopting our company elevator regulating voltage one, to raise the voltage to a value, the equipment starts voltage dropping, we compensate the voltage dropping, before the voltage drops to the contactor jump off to compensate the voltage up, the equipment starts normally, the voltage returns to the normal value.
