Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of transformer structures, and in particular to the technical field of an extractable structure for a dry-type transformer fan. Background Technology
[0002] With the continuous growth of electricity demand and the continuous advancement of power technology, the reliable operation of dry-type transformers is crucial in the power system. Traditional dry-type transformer fans are mostly fixed installations. Once the fan fails, the transformer must be stopped for maintenance and replacement. This not only affects the continuity of transformer operation, but may also cause economic losses due to power outages. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the prior art by proposing a withdrawable structure for the fan of a dry-type transformer, which allows the fan of the transformer to be withdrawn separately for maintenance and replacement without shutting down the transformer, thus greatly reducing equipment maintenance costs and extending the service life of the equipment.
[0004] To achieve the above objectives, this utility model proposes a withdrawable structure for a dry-type transformer fan, including an angle steel bracket, a transformer base, guide steel plate assemblies, limiting steel plates, guide slide rails, push-pull plate grooves, and fans. The transformer base is installed on the top of the angle steel bracket, and several sets of guide steel plate assemblies are arranged below the transformer base. The guide steel plate assemblies are fixedly installed on the top of the angle steel bracket. Each guide steel plate assembly consists of two parallel limiting steel plates. Guide slide rails are symmetrically arranged on the inner sides of the two limiting steel plates in the same guide steel plate assembly. Push-pull plate grooves are slidably installed on the guide slide rails, and several fans are fixedly installed inside the push-pull plate grooves.
[0005] Preferably, there are multiple sets of guide steel plates, which are symmetrically and evenly arranged on the front and back sides of the top of the angle steel bracket.
[0006] Preferably, the guide rail is composed of multiple sliding rails that are slidably fitted together. The inner end of the guide rail is fixed to the inner side of the limiting steel plate by bolts, and the outer end of the guide rail is fixed to the outer side of the push-pull plate groove by bolts. A limiting stop is provided at the outer end of the guide rail corresponding to the position of the limiting steel plate.
[0007] Preferably, the connection between the angle steel bracket and the transformer base is provided with several locking screws, and buffer washers are fitted on the locking screws.
[0008] Preferably, an auxiliary handle is provided on the outer side of the push-pull plate groove.
[0009] Preferably, the lower part of the auxiliary handle is provided with a limiting locking plate, and a locking bolt is inserted through the limiting locking plate. The outer side of the angle steel bracket is provided with a locking thread hole corresponding to the locking bolt position, and the locking bolt is detachably installed in the locking thread hole.
[0010] The beneficial effects of this utility model are as follows: This utility model combines an angle steel bracket, a transformer base, a guide steel plate assembly, a limiting steel plate, a guide slide rail, a push-pull plate groove, and a fan. After experimental optimization, when the fan needs maintenance, there is no need to shut down the transformer. The fan can be pulled out along the guide slide rail via the push-pull plate groove for maintenance or replacement, which greatly reduces equipment maintenance costs and extends equipment service life. The structure is reasonably designed, simple, and easy to process and manufacture, and has extremely high practical value and promotion significance.
[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
