Dry type transformer protection apparatus and use method thereof

Abstract

The invention discloses a dry type transformer protection apparatus. The dry type transformer protection apparatus comprises a transformer box; a dust removal shaft connected with a motor is arranged in the transformer box; the transformer body comprises an iron core, clamps and a coil winding; a base is arranged on the lower part of the transformer box; a supporting base is arranged on the lower part of the base; a T-shaped sliding groove is formed in the supporting base; rolling wheel grooves are formed in the lower part of the T-shaped sliding groove; fixed frames are arranged on the two sides of the transformer box; wiring terminals are arranged in the fixed frames; a door plate is arranged on the front side of the transformer box; the door plate comprises a left door plate and a right door plate; and an air outlet is formed in the lower part of the door plate. The invention also discloses a use method of the dry type transformer protection apparatus. The dry type transformer protection apparatus is small in occupied area, convenient to move and transport, and low in production cost; the interior of the transformer is in air circulation to perform heat dissipation in time, so that burn down of the dry type transformer by a high temperature can be prevented effectively and the service life of the transformer is prolonged; and in addition, the dry type transformer protection apparatus has convenience in checking and overhaul and high practical value.

Description

[0001] This application is a divisional application of an invention patent application named: A dry-type transformer protection device, the application date is: December 12, 2016, and the application number is: 201611136511.1. technical field [0002] The invention relates to the technical field of a transformer protective shell, in particular to a dry-type transformer protective device and a use method thereof. Background technique [0003] Transformer protection device is a high-tech product of power automation integrating protection, monitoring, control, communication and other functions. It is an ideal electrical unit that constitutes an intelligent switch cabinet. The product has a built-in protection library consisting of more than 20 standard protection programs, and has a complete and powerful acquisition function for the voltage and current analog and switch values ​​of primary equipment (the current measurement is realized through the protection CT). [0004] The C...

Problems solved by technology

[0005] The disadvantage of this patent is that the protective cover of the separated dry-type transformer is designed as two symmetrical front and rear parts. A large amount of heat will be generated during work. Putting the entire transformer in a closed space with a protective cover may cause excessive temperature inside the protective cover and cause unpredictable dangers; there is no corresponding transformer base in the protective cover of the separated dry-type transformer , A certain amount of moisture will accumulate under the transformer for a long time, which is not conducive to the operation of the transformer and will shorten the service life of the transformer; the protective cover of the separate dry-type transformer is directly fixed with anchor bolts. Although the reliability is high in a short period of time, it needs to be fixed regularly Check to avoid the loosening of the bolts, which consumes manpower and material resources. After being fixed with anchor bolts, the protective cover of the separated dry-type transformer is inconvenient to move
