Resin insulation dry-type transformer

Abstract

The invention discloses a resin insulation dry-type transformer which comprises a transformer main body, a base and a fan. The base is arranged at the bottom of the transformer main body, the fan is installed on the upper surface of the base, and one side of the fan is connected with a limiting mechanism; the limiting mechanism is connected with a butt joint mechanism, and the butt joint mechanism is located in the base. The butt joint mechanism is connected with a fixing rod, and the lower end of the fixing rod is fixedly connected with a connecting rack. According to the resin insulation dry-type transformer, the fan can be rapidly limited through the limiting mechanism and the butt joint mechanism, the accurate installation of the fan is facilitated, and meanwhile, fixing between the transformer main body and the base can be relieved by pushing a control block, the fan can be conveniently disassembled and assembled, and the disassembling and assembling rapidness can be improved, therefore, the time for disassembling and assembling the fan is effectively saved, the assembly efficiency of the resin insulation dry-type transformer is improved, and the large-scale production of the resin insulation dry-type transformer is facilitated.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a resin-insulated dry-type transformer. Background technique [0002] Resin insulated dry-type transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance. In order to ensure the normal operation of electrical equipment in use, it is necessary to use dry-type transformers to step up or step down the municipal power supply. At the same time Some types of dry-type transformers can play the role of safety isolation. In addition, the transformer can perform resistance-capacitance coupling and direct coupling, and can isolate the effect of direct current. Therefore, it is widely used in electronic technology, but the existing transformers are still The following problems exist; [0003] 1. When hoisting the common resin insulated dry-type transformers on the market, it is usually necessary to use additional auxiliary tools to su...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a resin-insulated dry-type transformer to solve the problem of the above-mentioned background technology. When hoisting the common resin-insulated dry-type transformers on the market, it is usually necessary to use additional auxiliary tools to support the transformer. After the auxiliary device is connected with the hoisting device, the hoisting work is cumbersome and not convenient enough. At the same time, the fan needs to be removed from the transformer during hoisting, and the fan needs to be installed after the hoisting is completed. The steps are cumbersome. And the operation is not fast enough, which is not conducive to the batch hoisting and transportation of transformers
