High-tenacity terminal board used for transformer and mutual inductor

Abstract

The high-toughness terminal board for transformers and transformers of the present invention has higher toughness and impact resistance, and completely solves the problem that the existing terminal boards for transformers and transformers are brittle and prone to fracture; and the structure of the present invention is compatible with The technical indicators can fully meet the current requirements for the use of transformers and transformers. The present invention comprises the lifting base of the transformer and the transformer, the housing arranged on the upper part of the lifting base, and the housing and the lifting base are fixedly connected by external installation bolts; the upper part of the lifting base and the inside of the housing are provided with a terminal board; the terminal board is composed of Carboxyl-terminated nitrile rubber and epoxy resin are mixed by vacuum casting. Mounting holes are evenly distributed around the terminal board, and internal mounting bolts are provided through the mounting holes, and are fixedly connected to the rising seat through the internal mounting bolts; A casing opening is provided; connecting terminals are evenly arranged and distributed on the terminal board, and the upper and lower ends of the connecting terminals are connecting terminals.

Description

technical field [0001] The invention belongs to the technical field of transformers and transformers, and in particular relates to a high-toughness terminal board for transformers and transformers. Background technique [0002] In the power transmission and transformation industry, terminal boards are widely used in transformers and transformers, and are important accessories for connecting output lines and control or testing equipment. [0003] Terminal boards are often divided into round, square and other rare shapes in terms of shape. As far as their structure is concerned, the terminal board is usually injected onto the polymer insulation material through the cooperation of the mold; at present, most of the domestic industries use modified epoxy. Resin is the main raw material, supplemented by other fillers, through a series of processing procedures such as vacuum stirring, pouring, and high temperature curing. Cracks and fractures of terminal boards still occur from ti...

Problems solved by technology

[0003] Terminal boards are often divided into round, square and other rare shapes in terms of shape. As far as their structure is concerned, the terminal board is usually injected onto the polymer insulation material through the cooperation of the mold; at present, most of the domestic industries use modified epoxy. Resin is the main raw material, supplemented by other fillers, through a series of processing procedures such as vacuum stirring, pouring, and high temperature curing. Cracks and fractures of terminal boards still occur from time to time, and the problem of transformer oil leakage is not uncommon, which brings hidden dangers to the normal operation of transformers and transformers
