Glass fibre reinforced plastic capacitance multicore transformer bushing

Abstract

The invention relates to a glass fibre reinforced plastic capacitance multicore transformer bushing which not only has the functions of common transformer bushings, and what's more is capable of simultaneously leading out a plurality of through cable leads with similar voltages and belongs to the technical field of high-voltage engineering in dynamic and electronic engineering. Due to the fact that the traditional transformer no-load voltage-regulating tap is in the transformer, a test means for testing whether the contact between moving contacts and fixed contacts of the tap is reliable or not is lacking all along, whereas if the no-load voltage-regulating tap is arranged outside the transformer, the technical problem can be easily solved. In order to achieve the goal, the invention daringly orientates the key technical scheme under the premise that the internal structure of the transformer is not basically changed to realize the extraposition function of the no-load voltage-regulating tap only by a multicore bushing. Adopting the technology of the invention not only reduces the installation volume of the transformer but also greatly reduces the economic cost, and therefore, the transformer bushing can be widely applied to no-load voltage-regulating transformers.

Description

Technical field: [0001] The invention relates to a fiberglass capacitive multi-core transformer bushing, which not only has the function of a common transformer bushing, but also has the function of simultaneously leading out a plurality of cable lead wires with similar voltages. Background technique: [0002] Since the traditional no-load voltage regulation tap of the transformer is inside the transformer, after the no-load voltage regulation operation is completed, there is no foolproof inspection method to ensure whether the contact between the dynamic and static contacts of the tap is reliable. If the on-load voltage regulating tap is placed outside the transformer, the above problems can be easily solved, thereby improving the safe operation level of the transformer. [0003] In order to achieve the purpose of placing the off-load tap tap outside the transformer, a simple method is to provide a traditional cable-through transformer bushing for each lead wire connected t...
