Composite type cabinet type transformer substation

Abstract

The composite box type transformer substation includes following parts and structures: the substation is composed of prefabricated base from reinforced concrete, steel engine seat, dry type transformer, working footplate for inspection and repair, and machine room; dry type transformer is fixed on steel engine seat; through foundation bolt of fixing engine seat, and foundation bolt of fixing wallboards of machine room, the steel engine seat and wallboards are fixed on the prefabricated base from reinforced concrete; there are through holes for anchor bars and cables; through the said holes, grounding anchor bars fix prefabricated base on ground surface, and cables are connected to transformer and related equipment; through clipping junction piece, the working footplate is fixed on side ofthe steel engine seat. Comparing with prior art, the invention possesses features of on site assembly, and short construction period, easy of maintenance etc.

Description

1. Technical field [0001] The invention relates to a power transmission and transformation technology, in particular to a combined box-type substation. 2. Background technology [0002] The traditional wet-type power transformer with oil immersion cooling has been replaced by a dry-type transformer. Due to its small size and good safety, the dry-type transformer is mostly installed on the ground, and then a box-type machine room is built outside, so it has the characteristics of a box-type machine room. The substation composed of dry-type transformers is also called box type substation. [0003] The box-type transformer is usually fixed on the machine base made of concrete. The machine base is generally dug on the ground according to the size of the machine room. A part of it is on the ground. The computer room is also mostly made on-site. The deficiencies in the practical application of this box-type substation base in the prior art are: (1) The construction is difficult...

AI Technical Summary

Problems solved by technology

The deficiencies in the practical application of this box-type substation base in the prior art are: (1) The construction is difficult, and the construction process is easily affected by temperature and climate. For example, in winter construction, the mixing, transportation and pouring of concrete are difficult Affected by temperature, in summer it is affected by rain; (2) consumes a lot of building materials and manpower and material resources; (3) the construction period is long, and cannot be used on the same day of construction; (4) if the box-type machine room needs to be demolished, Transformers, machine rooms and other related equipment can be removed, but the cement base left behind cannot be removed, and rural farmland will be occupied for a long time; there is no good solution yet

In addition, dry-type transformers are mostly installed on special racks on the base, and the outside of the transformer is a box-type machine room with a very compact structure. However, since the dry-type transformer is fixed in the machine room with a very narrow space, there is only a small space between the transformer and the wall panel of the machine room that allows one person to pass through. Great inconvenience and no good solution at the moment
