Problems solved by technology

In order to prevent the surface of the pile head from being oxidized and reduce the electrical contact performance, it is also necessary to tin-plate the busbars welded to the pile head as a whole. This has two disadvantages: one is that the overall welded pile head is easily deformed, which affects the dimensional accuracy of the pile head and The reliability of plugging and mating in the future; the second is that the overall tinning cost of the busbar is relatively high and unnecessary

Embodiment Construction

[0010] As shown in the figure, the tap head of the intensive bus duct socket includes a pile head 1 and a busbar 2, and a notch 21 for the pile head to be embedded is opened on the edge of the busbar. The overall pile head has an "inverted T-shaped" structure, that is, it is composed of a wider root 11 and a narrower main body 12 . The root 11 of the pile head is embedded in the notch 21 of the busbar, and a welded connection section 3 is respectively arranged between the two sides of the pile head and the busbar. The lower section of the root 11 of the pile head is "inverted trapezoid", and the welded connection section 3 extends from the two waist parts of the "inverted trapezoid" structure to the two sides of the bottom edge, so that a larger welded connection area can be obtained to meet the strength and load requirements. flow performance requirements.

Abstract

The invention relates to a transmission equipment accessory, in particular to a tapping pile head of a plug socket of an intensive bus duct for use in a tapping device of the intensive bus duct. The tapping pile head of the plug socket of the intensive bus duct comprises a pile head and a bus bar which are connected with each other. The edge of the bus bar is provided with a notch for the pile head to be embedded in. The pile head consists of a wider root part and a narrower body part and takes a reverse 'T'-shape on the whole. The root part of the pile head is embedded in the notch of the bus bar. A welded connection section is arranged between each of two sides of the root part of the pile head and the bus bar. The invention has the advantages of simple manufacturing process, good economical efficiency, insusceptibility to deformation and contribution to the improvement of the reliability of tapping contact.

Description

technical field [0001] The invention relates to an accessory of power transmission equipment, in particular to a tap pile head for an intensive bus duct socket tap used in a dense bus duct tapping device. Background technique [0002] As a kind of power transmission and distribution equipment, the bus duct is one of the most basic and important electrical properties, and the socket device is an important guarantee for the reliability of the tap. [0003] There are usually two types of outlet taps for intensive bus ducts. One is to bend the busbar at the socket to increase the distance between the busbars so that the plug-in device can be directly connected to the busbar; the other is to bend the busbar at the socket. Row up soldered tap posts for easy insertion. The first method is less used due to the complex process, while the second method is currently widely used current tap method. At present, the structure and process commonly used in the second method above is to fi...
