Transformer low-voltage bushing drainage wire clamp

Abstract

The invention relates to a transformer low-voltage bushing drainage wire clamp, and belongs to the technical field of transformer lead connection. The transformer low-voltage bushing drainage wire clamp comprises a main clamp and an auxiliary clamp, a worm gear and a worm which are matched through a gear are arranged in the cheek of the main clamp, a square groove is formed in the worm gear, the auxiliary clamp is installed on the square groove, the bottom of the worm is fixed through a shaft sleeve, the upper portion of the worm is fixed through a fixing cover plate, and the portion, stretching out of the main clamp, of the worm is covered through an insulating cover. A conductive braid is fixed between the main clamp and the auxiliary clamp through a conductive band pressing plate, conductive band pressing plates are arranged in clamping mouths of the main clamp and the auxiliary clamp, the surfaces of the main clamp and the auxiliary clamp are covered with insulating plates, and a drainage tube is installed at the bottom of the main clamp through threads. The wire clamp is low in manufacturing cost, efficient and simple in structure, capable of adapting to transformer binding posts with different diameters, high in universality and suitable for being applied to transformer low-voltage bushings on a large scale.

Description

technical field [0001] The invention relates to a transformer low-voltage bushing drainage clamp, which belongs to the technical field of transformer lead wire connection. Background technique [0002] Power transmission and distribution equipment is an important part of national economic and social development. In recent years, my country's power grid construction investment has continued to increase, and the number of power generation and substations has grown rapidly. However, there is still a gap between the level of electricity consumption and the international advanced level. The development of urban and rural areas is unbalanced, and the quality of power supply needs to be improved. In the past, the low-voltage bushing drain clips used to draw current from the transformer have disadvantages such as inconvenient use, not firm, and easy to damage. Moreover, because the diameters of the low-voltage bushing terminals of different transformers are different, it is often ne...

Problems solved by technology

In the past, the low-voltage bushing drain clips used to draw current from the transformer have disadvantages such as inconvenient use, not firm, and easy to damage. Moreover, because the diameters of the low-voltage bushing terminals of different transformers are different, it is often necessary to match different terminals according to the specifications of the terminals.
