specific Embodiment 2

[0052] Specific embodiment 2 of the busbar power transmission system of the present invention. In this embodiment, the structure of the busbar power transmission system is simplified. In this embodiment, the busbar power transmission system includes a busbar duct and a busbar duct supporting device supporting the busbar duct. The busbar duct supporting device It includes a support seat for supporting the bus duct, on which a bus assembly structure is provided, and the bus assembly structure has a structure for the bus duct to pass through for sliding fit with the bus duct along the axial direction of the bus duct and along the radial direction of the bus duct. The busbar slideway that fits in the direction of the busbar duct. By setting the busbar assembly structure, the busbar duct can slide along the axis of the busbar duct when thermal displacement occurs, so as to avoid damage to the busbar duct and the supporting seat.

specific Embodiment 9

[0059] Embodiment 9 of the bus power transmission system of the present invention, as a further optimization of any one of Embodiments 2 to 7, the bus assembly structure further includes a buffer structure arranged between the bus duct and the bus slideway. Certainly, no buffer structure may be provided in other embodiments.

[0060] The specific embodiment 10 of the bus power transmission system of the present invention, as a further optimization of the specific embodiment 9, the buffer structure is a heat-shrinkable sheath arranged between the bus duct and the bus slideway. Certainly, in other embodiments, the buffer structure may also be a rubber pad provided on the bus bar clamp.

[0061] The specific embodiment 11 of the busbar power transmission system of the present invention, as a further optimization of any one of the specific embodiments 2 or 3, the support seat includes a seat body and a sliding seat slidingly assembled on the seat body, and the busbar assembly stru...

specific Embodiment 20

[0070] The specific embodiment 20 of the bus power transmission system of the present invention differs from the specific embodiment 1 of the bus power transmission system of the present invention only in that the supporting seat is an integrated tubular structure.

[0071] The specific embodiment 21 of the bus power transmission system of the present invention differs from the specific embodiment 1 of the bus power transmission system of the present invention only in that the slider is cylindrical and extends towards the radial direction of the bus duct, and the slide rail is cylindrical The sliding block is matched with the cylindrical sliding rail, and the two side walls of the notch of the cylindrical sliding rail are slidably matched with the web.

Abstract

The invention provides a busbar power transmission system and a busbar pipeline support device thereof, which belong to the field of electric equipment. The busbar pipeline support device includes a support seat for supporting the busbar pipeline, and the busbar assembly structure is provided on the support seat. The busbar assembly structure has a The pipe passes through the busbar slideway for sliding fit with the busbar duct along the axial direction of the busbar duct and limited fit with the busbar duct along the radial direction of the busbar duct. When the bus duct is displaced along its axial direction, the bus duct slides in the bus slideway, avoiding the stress damage of the bus duct and the support seat, and solving the problem that the bus duct is easily damaged due to thermal displacement in the prior art.

Description

technical field [0001] The invention relates to a busbar power transmission system and a busbar pipe support device thereof. Background technique [0002] In recent years, with the rapid development of economy and industry, the demand for installed capacity of power grids at home and abroad has gradually increased. As a transmission form that may replace overhead lines, power cables and wall bushings, gas-insulated metal-enclosed transmission lines (GIL) are used in It has been increasingly widely used in long-distance, large-capacity and special environmental conditions. When the GIL bus duct is used for long-distance and large-capacity power transmission, the axial deformation caused by the thermal expansion and contraction effect is relatively obvious, and the stress will pose a hazard to the safe operation of the GIL bus duct. However, if the support of the bus duct is fully rigidly connected to the GIL shell, the shell will be restrained by the support when it deforms ...
