Description

Integrated transformer substation

Technical field

The utility model patent relates to a kind of 35kV-126kV surface protection type integrated transformer substation, is applicable to that electric power system 50Hz, 40.5kV-126kV city agricultural power network and large enterprise's symbolic animal of the birth year are subjected to the usefulness of electricity, transformation and distribution with the electric power terminal equipment of voltage level.

Technical background

1,35kV-126kV transformer station mostly is applied to the usefulness that the affiliated electric power terminal equipment of city agricultural power network and some large enterprises is subjected to electricity, power transformation and distribution.Because the regular given 35kV-126kV transformer station loop fault opening time of relaying protection is too short; the protective relaying device of using can not be by the numerical value of adjusting of standard at present; in official hour, finish the action of excision fault; the overstep tripping so often break down causes large area blackout.

2, existing 35kV-126kV transformer station floor space is generally about 4 mu～10 mu, and this type of transformer station's consumption is increasing, has just become subject matter so electric power takes up an area of.For this reason, the national grid indication will reduce radius of electricity supply as far as possible, and the strict construction quantity that controls the 35kV-126kV transformer station of traditional civil structure.

3, press basic configuration such as 35kV-126kV double loop main transformer 2*5000kVA, wherein the soil is 5 mu, calculating such as 6 on family layer and big gauge rod fiduciary point ground, and 35kV-126kV transformer station generally makes an investment in about 3,000,000～4,000,000 at present.Fund input is extension of rural power grids investment aspect particularly, also becomes very important problem.

4, present domestic 35kV-126kV transformer station all is an outdoor equipment generally, and low power equipment weatherability is not good in China, and antiacid rain and ability and ultraviolet resistance are poor, makes substation equipment often spontaneous corrosion occur and needs interruption maintenance outside the plan influences normal power supply.

Summary of the invention

The utility model patent provides the integrated transformer substation of the non-civil structure of a kind of surface-protection type.This transformer station adopts PLC face protection philosophy, can prevent the fault overstep tripping; 40.5kV-126kV switchgear, main transformer, 10kV switchgear be the main body layered arrangement successively, wiring is simple and direct; Top cover is rainproof, sun-proof, and shutter natural draft all around can reduce equipment spontaneous corrosion in the institute, prolongs service life of equipment; Floor space only be operation at present same scale transformer station 1/5～1/6, gross investment reduces 30%～40%.

The technical scheme that the utility model patent technical solution problem is taked is: fixedly lower floor's steelframe, upper strata steelframe and top cover on the underframe of integrated transformer substation, the and arranged on left and right sides of upper strata steelframe be transformer station into and out of the line side, be used separately as 12kV high-tension apparatus chamber, 40.5kV-126kV high-tension apparatus chamber, indoor two cover 40.5kV-126kV service entrance switch equipment and the two cover main transformer service entrance switch equipment fixed of 40.5kV-126kV high-tension apparatus; Indoor two cover main transformer outlet switchgears, the two cover 12kV capacitor devices and eight～20 cover 12kV feeder switch equipment fixed of 12kV high-tension apparatus, two main transformers are fixed by central authorities in the upper and lower layer steelframe, between two main transformers, all have dividing plate to isolate between two main transformers and two high-tension apparatus chambers, remainder is fixed a 10/0.4kV house transformer successively in lower floor's steelframe, corresponding to the operation control of 12kV switchgear, corresponding to operating control device and this institute face protection control device of 40.5kV-126kV switchgear; 40.5Kv-126kV bar coupler is fixed between the two cover 40.5Kv-126kV service entrance switch equipment; The 12kV bar coupler, be fixed on the middle part of eight covers～two ten cover 12kV feeder switch equipment, outer surface is all installed shutter around this transformer station, the front, rear, left and right face of transformer station is equipped with access door, and described 40.5kV-126kV service entrance switch equipment and main transformer service entrance switch equipment are outdoor high-voltage permanent magnet mechanism one solid sealing type vacuum circuit breaker; 12kV feeder switch equipment and main transformer outlet switchgear are the outdoor high-voltage permanent-magnetic mechanism sealing type vacuum circuit breaker.
