Three-phase dry-type transformer based on adjustable insulator outgoing structure

Abstract

The invention relates to a three-phase dry-type transformer based on an adjustable insulator outgoing structure. The transformer comprises a transformer body. A fixation frame is arranged on the transformer body. An adjustment mechanism is arranged on the upper end of the fixation frame. Mobile pay-off mechanisms are symmetrically arranged on the left and right ends of the adjustment mechanism. The middle of the front end of the fixation frame and the front end of the mobile pay-off mechanisms are provided with insulators. The transformer provided by the invention solves the problems that in the temporary circuit test process of the existing three-phase dry-type transformer a the installation of insulators needs to be adjusted when power lines of different standards and structures are connected with the transformer; the use of a traditional transformer requires insulators to be removed to determine the installation location; frequent removal and installation of insulators can easily lead to loosening of the installation location; and b when the installation location of insulators changes, wires are heated and the temperature between twisted wires increases during a test, which maycause a fire and affects the use flexibility of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a three-phase dry-type transformer based on an adjustable insulator outlet structure. Background technique [0002] Three-phase dry-type transformers are the main components of various power supplies and electrical equipment. Transformers play a vital role in power transmission. When building power lines, temporary three-phase dry-type transformers are used to test the quality of the test circuit. During the test, the distance between the lines should be determined according to the distance between the lines. Adjust the installation position of the insulator on the transformer.

Problems solved by technology

[0003] However, the existing three-phase dry-type transformers have the following problems in the temporary test circuit process: a. When connecting power lines of different structures and standards to the transformer, it is necessary to adjust the installation of the insulators. When using a traditional transformer, the insulators need to be disassembled. Determine the installation position and adjust the distance between insulators to meet the standards of power lines. Frequent disassembly and installation of insulators will easily lead to loose installation positions, and the installation and disassembly of insulators must be carried out in accordance with strict safety standards, which is complicated to operate

b. When the installation position of the insulator changes, it is necessary to manually adjust the arrangement of the wires between the insulator and the transformer. The connected wires are too long to be entangled with each other. During the test, the temperature between the wires heats up and the temperature between the wound wires increases, which may cause a fire , affecting the flexibility of transformer use

[0004] For the technical problems existing in the use of transformers, personnel in related technical fields have conducted research and made adaptation improvements. For example, the Chinese invention patent No. 201811066977.8 is a low-loss energy-saving power transformer, which can reduce the use of transformers. However, the problems existing in the temporary test circuit of the existing three-phase dry-type transformer mentioned above need to be solved urgently
