Description

Surface protection type integrated transformer substation

(1) technical field

The utility model relates to a kind of 35kV surface protection type integrated transformer substation, is applicable to that electric power system 50Hz, 40.5kV 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.

(2) technical background

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

2, existing 35kV transformer station floor space is generally about 4 mu～6 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 transformer station of traditional civil structure.

3, press basic configuration such as 35kV double loop main transformer 2*500kVA, wherein the soil is 5 mu, calculating such as 6 in house and big gauge rod fiduciary point ground, and 35kV transformer station generally makes an investment in about 3,000,000 yuan～4,000,000 yuan at present.Fund input is extension of rural power grids investment aspect particularly, also becomes very important problem.

4, present domestic 35kV transformer station all is an outdoor equipment generally, and China's mesolow power equipment weatherability is not good, 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.

(3) summary of the invention

The utility model provides a kind of surface protection type integrated transformer substation, the integrated transformer substation of non-civil structure.It can prevent the fault overstep tripping, and chpn arranges that wiring is simple and direct, and spontaneous corrosion is little, and service life of equipment is long, and floor space is little, small investment.

The technical scheme that the utility model technical solution problem is taked is: fixedly lower floor's steelframe, upper strata steelframe, wallboard and top cover all around successively on the underframe, the and arranged on left and right sides of upper strata steelframe be respectively transformer station into and out of the line canyon, lower floor's steelframe is corresponding control device chamber, central authorities are for there being main transformer room, shutter and front, rear, left and right access door all are installed on the wallboard all around, and top cover is fixed on the upper end of upper strata steelframe; Described inlet wire canyon internal fixation two cover 40.5kV service entrance switch equipment and two cover main transformer service entrance switch equipment, described output equipment room internal fixation two cover main transformer outlet switchgears, two cover 10kV capacitor devices and eight cover 12kV feeder switch equipment, two main transformers of described main transformer room internal fixation, between two main transformers, two main transformers with advance, the high pressure dividing plate is all arranged between the output equipment room, and described control device is indoor fixes a 10/0.4kV house transformer, operating control device corresponding to 40.5kV service entrance switch equipment, operating control device and face protection control device corresponding to 12kV feeder switch equipment; 40.5kV bar coupler is fixed between the two cover 40.5kV service entrance switch equipment; The 12kV bar coupler is fixed on the middle part of eight cover 12kV feeder switch equipment.

Described 40.5kV service entrance switch equipment and main transformer service entrance switch equipment are 40.5kV outdoor high-voltage permanent magnet mechanism one solid sealing type vacuum circuit breaker; 12kV feeder switch equipment and main transformer outlet switchgear are 12kV outdoor high-voltage permanent-magnetic mechanism sealing type vacuum circuit breaker.

The utility model adopts PLC face protection philosophy, can prevent the fault overstep tripping; 40.5kV switchgear, main transformer, 12kV switchgear chpn successively arrange that 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%.
