Abstract

The invention discloses a compact dry-type transformer. The transformer comprises a shell, and a voltage transformation device and a ventilation device arranged in the shell, the shell comprises a base, supporting rods, a top plate and a surrounding plate. The top plate is arranged at one side of the base; grooves are formed in the sides, facing the coamings, of the base and the top plate and connected with the coamings in a clamped mode, the supporting rods are connected with the base and the top plate, the coamings are arranged between the top plate and the base, each coaming comprises semicircular plates and connecting plates, the number of the semicircular plates corresponds to that of the voltage transformation devices, and the semicircular plates and the connecting plates are sequentially connected at interval to form a ring shape. According to the technical scheme, main support is supported and stressed by the base, the supporting rods and the top plate which are connected withone another, the coamings are used for packaging and providing dustproof and waterproof capacity, each coaming comprises the semicircular plate and the connecting plate, the coamings are convenient todisassemble and assemble during maintenance and installation, and the coamings can be disassembled and assembled under the condition that a voltage transformation device is not affected.

Description

technical field

[0001] The invention relates to the field of power distribution equipment, in particular to a compact dry-type transformer. Background technique

[0002] Existing encapsulated transformers can be used indoors or outdoors, and have a wide range of applications. The maintenance and repair of transformers are mainly carried out on the substation, so it is necessary to disassemble the casing and encapsulate, while compact dry-type transformers are used. In order to reduce the floor space, the distance between the encapsulation shell and the substation is generally set close, and it is not easy to disassemble and assemble the shell, which seriously affects the work efficiency of the staff. SUMMARY OF THE INVENTION

[0003] The main purpose of the present invention is to provide a compact dry-type transformer, which aims to solve the problem that the existing transformer shell is not easy to disassemble and assemble.

[0004] In order to achieve the above object...
