Setting device for axial press force of transformer winding

Abstract

The invention provides a setting device for an axial press force of a transformer winding. The setting device comprises a fixed upper disc, a press plate lower disc and at least two setting screw rods, wherein the at least two setting screw rods are arranged in parallel between the fixed upper disc and the press plate lower disc, the fixed upper disc is fixedly arranged right above the transformer winding, the press plate lower disc props against a top part of the transformer winding, two ends of each length-adjustable setting screw rod are respectively connected with the fixed upper disc and the press plate lower disc, so that the press plate lower disc can generate displacement relative to the fixed upper disc. In the setting device provided by the invention, the axial press force of the transformer winding is accurately set by controlling the displacement of downward motion of the press plate lower disc, the setting device is simple in structure and high in applicability and is convenient to operate, and a method is provided for setting the axial press force of a transformer which is actually designed and produced.

Description

technical field [0001] The invention belongs to the technical field of transformer production, and in particular relates to a setting device for the axial compression force of transformer windings. Background technique [0002] As one of the most important equipment in the power system, the power transformer belongs to a category that is expensive but has a large role and involves a wide range of areas, so the research on ensuring its safe operation is of great significance. With the continuous development of the national economy, the demand for electricity is increasing, and power transformers tend to develop in the direction of high voltage and large capacity. This higher pursuit of performance increases the strength of its internal electric field and magnetic field, resulting in the electrical, thermodynamic and mechanical performance of the coils, leads, tap changers and other components of the power transformer and even the surface of the transformer oil tank. question...
