Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage power distribution equipment, specifically relating to a double-lead installation structure for equipment ends of large-span high-voltage power distribution equipment. Background Technology

[0002] Both high-voltage power distribution devices, as well as the high-voltage power distribution devices and the busbar, are connected by lead wires. For example... Figure 1 , 2 As shown, a horizontal mounting plate 301 is installed at the top of the vertically mounted equipment bushing 3 of the high-voltage power distribution equipment. A pre-existing vertical terminal plate 2 is mounted on the horizontal mounting plate 301, positioned above it. An equalizing ring 5, which is prior art, is mounted on the horizontal mounting plate 301. The pre-existing vertical terminal plate 2 is connected to the lead wire 10 via a pre-existing clamp 1. The horizontal mounting plate 301, the pre-existing vertical terminal plate 2, and the pre-existing clamp 1 are all located within the equalizing ring 5. The pre-existing clamp 1 includes a vertical connecting plate 101 and a pre-existing horizontal connecting arm 102 located on one side of the upper end of the vertical connecting plate 101. The length direction of the pre-existing horizontal connecting arm 102 is parallel to the width direction n of the vertical connecting plate 101. Two pre-existing horizontal connecting arms 102 are provided, located at opposite ends of the length direction of the vertical connecting plate 101 and on the same side of the vertical connecting plate 101. One end of each original horizontal connecting arm 102 is connected to the vertical connecting plate 101, and the other end of each original horizontal connecting arm 102 is provided with an original horizontal sleeve 103 arranged coaxially with itself. The original horizontal sleeve 103 is connected to the lead wire 10. The vertical connecting plate 101 is connected to the original vertical terminal plate 2 by a number of mounting bolts 4. The width direction m of the original vertical terminal plate 2 is parallel to the width direction n of the vertical connecting plate 101, and both are parallel to the tension direction L of the two lead wires 10.

[0003] The above installation structure forms a double-lead installation structure for the equipment end of the high-voltage power distribution equipment. Typically, the original vertical terminal block 2 has a width of 24mm, a length of 240mm, and a height of 240mm. For the 500kV busbar of the HGIS substation, the span of the lead connection is usually 4-6 meters. The above-mentioned double-lead installation structure for the equipment end of the high-voltage power distribution equipment can be used without the need for additional support insulators and equipment brackets in the middle. If the span of the lead connection is too large, for example, greater than 10 meters, it is necessary to add support insulators and equipment brackets in the middle to support the lead; otherwise, the original vertical terminal block 2 will deform due to excessive stress, affecting the normal operation of the equipment.

The first horizontal sleeve 604 and the second horizontal sleeve 704 are located on the same side of the width direction b of the vertical terminal plate 8.
