Abstract

The invention relates to an end screen leading-out mechanism, which comprises: a first clamping assembly provided with a first conductive part; a second clamping assembly provided with a second conductive part matched with the first conductive part in a clamping manner, wherein the first conductive part and the second conductive part are matched with each other to be used for extending into an endscreen port and acting on a leading-out pin in the end screen port; and a pressure applying piece used for applying pressure to the first clamping assembly and / or the second clamping assembly, so that the first conductive part and the second conductive part get close to each other. According to the invention, the end screen leading-out mechanism does not need to be held by hands, can be stably fixed on an end screen pin, can effectively lead out an end screen pin signal, does not touch a grounding shell, and reduces or even avoids electric shock accidents.

Description

technical field [0001] The invention relates to the technical field of transformer bushings, in particular to an end screen lead-out mechanism. Background technique [0002] With the development of transformer technology, transformer bushings have appeared. Transformer bushings are an important part of power transformers. They mainly realize the connection, ground insulation and support of the transformer's internal outlets. Due to the severe working conditions of bushings, they are often gradually degraded or damaged due to environmental influences, resulting in grid failures. In order to ensure the normal operation of the power grid, it is necessary to carry out effective preventive tests and on-line monitoring on the bushings. When testing the transformer bushings on site, the design of the lead-out pins at the end of the traditional transformer bushing is relatively compact, and the dielectric loss and insulation of the bushings During the resistance test, it is necessa...
