Abstract

The invention provides a preassembled transformer station with a good ventilation structure. The preassembled transformer station comprises a box body, a top cap and a foundation; the top cap is arranged at the top of the box body; the box body is arranged on the foundation; the interior of the box body is divided into three partition chambers, namely a high-pressure chamber, a transformer chamber and a low-pressure chamber in which a high-pressure switch cabinet, a transformer and a low-pressure switch cabinet are arranged respectively; the box bottom of the transformer chamber, positioned below a transformer mounting rail, is provided with an air vent; the upper part of a transformer doorframe of the transformer chamber is provided with a box body shutter; four corners of the top of the transformer chamber are provided with four exhaust fans; four sides of the top cap are provided with top cap shutters; and two sides of a position corresponding to the transformer chamber on the foundation are provided with one or two foundation shutters respectively. The preassembled transformer station can fully cool radiators at the bottom and four sides of the transformer, improve the allowable capacity of the transformer, and prolong the service life of the transformer.

Description

A kind of preassembled transformer station

Technical field

The present invention relates to a kind of distribution substation of urban distribution network, be specifically related to the prepackage type box-type substation.

Background technology

The preassembled transformer station of extensive use at present, owing to standard GB/T17467 proposes to explicitly call for to the ventilation of transformer room, so its ventilating system is all perfect inadequately.The employing natural draft is arranged, the fin that adopts cooling blower to blow transformer is also arranged, perhaps pull out wind on top, transformer room, the heat that transformer is sent distributes effectively, thereby capacity is used in the permission that has reduced transformer.

Summary of the invention

The objective of the invention is to above-mentioned defective, a kind of preassembled transformer station with good ventilation structure is provided at existing preassembled transformer station existence.

Technical scheme of the present invention is: a kind of preassembled transformer station, comprise casing, top cover and basis, described top cover is installed in the top of casing, casing is installed on the basis, be divided into three compartments in the casing, be the hyperbaric chamber, transformer room and low-pressure chamber are equipped with high-tension switch cabinet, transformer and low-tension switch cabinet respectively in it; At the bottom of the case of described transformer room, be positioned at the transformer mounting rail below be provided with ventilation hole, the transformer doorframe top of described transformer room has the casing blind window, four air exhausters are equipped with at four angles, top, transformer room, have the top cover blind window around the described top cover, ground around the ratio of basis is raised 50 to 100 centimetres, and respectively drive one or two basic blind window, with convenient air intake in the both sides, position corresponding, basis with the transformer room.

All be equipped with on all ventilation holes and the blind window among the present invention and prevent that toy from entering the steel wire in the casing.

The invention has the beneficial effects as follows: the present invention can make the radiator around transformer bottom and the transformer fully be cooled off, and improves transformer and allows the use capacity, increases transformer useful life.

Embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments:

To shown in Figure 5, top cover 1 of the present invention is contained in the top of casing 3 as accompanying drawing 1, and casing 3 is installed on the preassembled transformer station basis 4, and blind window 6 is higher than terrace 5, and apparatus arrangement is the order font in the casing, is followed successively by hyperbaric chamber 10, transformer room 11 and low-pressure chamber 12.Cold wind sucks from the basic blind window 6 on the preassembled transformer station basis 4, and the ventilation hole 8 below the transformer mounting rail is to transformer bottom and the cooling of radiator all around thereof; Absorbed the hot-air of transformer heat, risen to casing top, one tunnel casing blind window 2 through transformer doorframe top is dissipated to outside the casing, and another road is drawn to the case top through air exhauster 7, is dissipated to outside the casing by the top cover blind window 9 around the top cover 1.
