Description
Technical Field
The present invention relates generally to gas insulation systems, and more particularly to a sliding bearing arrangement for a gas insulation system and a gas insulation system comprising the sliding bearing arrangement.
Background
Typically, the gas insulation system includes a housing, an inner conductor, and other accessories. The housing may define an enclosed space and be filled with, for example, SF6The insulating gas of (1). Electrical devices/components such as circuit breakers, disconnectors, conductive tubes, etc. may be arranged in the enclosed space for safe electrical operation. Common gas-insulated systems include, for example, gas-insulated switchgear (GIS) and gas-insulated transmission line (GIL).
The housing of the GIL and the housing of the GIS bus bar generally have a long length, requiring a plurality of support assemblies to be disposed along the axial direction of the housings for support. Fig. 1 shows a prior art support assembly, which may comprise a fixed support assembly 1 and a sliding support assembly 2, wherein the fixed support assembly 1 is fixedly connected with the GIL or GIS housing 3, while the sliding support assembly 2 allows the GIL or GIS housing 3 to slide in an axial direction within the sliding support assembly 2 upon thermal expansion and contraction.
However, the GIL or GIS bus bar may vibrate and generate a large abnormal sound due to the influence of factors such as power supply, wind power, and terrain variation. The prior art sliding bearing assemblies are unable to absorb the vibrations and often require re-installation or addition of the sliding bearing assemblies in an attempt to reduce the vibrations, but these approaches are often inefficient and take a significant amount of time and additional cost.
SUMMERY OF THE UTILITY MODEL
The present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide an improved sliding bearing device for a gas insulation system.
The present invention provides a sliding bearing arrangement for a gas insulation system for supporting a tubular housing of the gas insulation system, the sliding bearing arrangement comprising: a hoop assembly sleeved outside the tubular housing to allow the tubular housing to slide along an axial direction thereof, the hoop assembly having a base portion with first and second opposing surfaces; a support member supporting the base of the hoop assembly; and the mounting assembly comprises a limiting part and an elastic part. Wherein the base is mounted to the support member by the mounting assembly such that the first surface of the base faces the support member, and the stopper is disposed to support the first surface of the base, the resilient member being disposed to resiliently abut the second surface of the base.
The stopper of the sliding support apparatus according to the present invention may stably support the hoop assembly and the gas insulation system through the first surface of the support base, and the elastic member may provide buffering and absorbing vibration by elastically abutting the second surface of the base when the tubular housing of the gas insulation system vibrates, thereby reducing abnormal noise caused by the vibration. In addition, because the locating part supports the gas insulation system, namely bears the weight of the gas insulation system, the elastic part does not need to bear the weight of the gas insulation system, and only needs to bear a certain acting force when the gas insulation system vibrates, so that the elastic part has better durability and reliability.

In some alternatives, the support member defines a first mounting aperture, the base defines a first mounting aperture, the mounting assembly includes a first externally threaded fastener extending through the first mounting aperture and the first mounting aperture, the first externally threaded fastener being secured to the support member, and the stop is in the form of a stop nut and is in threaded engagement with the first externally threaded fastener. The stop member is threadedly engaged with the first externally threaded fastener such that the position of the stop member on the first externally threaded fastener can be adjusted to thereby adjust the spacing between the base of the hoop assembly and the support member, thereby allowing the height of the support point provided by the sliding support apparatus for supporting the tubular housing to be adjusted, which also helps to reduce vibration of the tubular housing.
In some alternatives, the support member defines a second mounting aperture, the base defines a second mounting aperture, the mounting assembly includes a second externally threaded fastener extending through the second mounting aperture and the second mounting aperture, and the resilient member is disposed externally of the second externally threaded fastener.

In the illustrated embodiment, the mounting assembly 106 may also include a stop washer 148. A stop washer 148 may be disposed between the elastic member 116 and the set nut 140 for stopping the elastic member 116. Thus, one end of the resilient member 116 may abut the second surface 112 of the base 108 and the other end may abut the stop washer 148.
By providing the retaining member 114 and the elastic member 116 abutting against the first surface 110 and the second surface 112 of the base 108, respectively, the retaining member 114 can stably support the base 108 of the hoop assembly 102 and the gas insulation system 200 from below, and the elastic member 116 can elastically abut against the base 108 of the hoop assembly 102 from above to provide shock absorption when the tubular housing 202 of the gas insulation system 200 vibrates, thereby reducing abnormal noise caused by the vibration.
Additionally, the mounting assembly 106 may also include a bushing 150. A bushing 150 may be disposed between the second externally threaded fastener 138 and the resilient member 116 to reduce friction between the resilient member 116 and the second externally threaded fastener 138 (e.g., the external threads of the second externally threaded fastener 138) when the resilient member 116 is elastically deformed in the axial direction of the second externally threaded fastener 138, thereby reducing potential wear and corrosion caused by wear. In the illustrated embodiment, the bushing 150 may extend through the second mounting hole 146. One axial end of the bushing 150 abuts the stop washer 148 and the other axial end abuts the upper portion 124 of the support member 104.
It is contemplated that the bushing 150 may not be provided; accordingly, external threads may be machined only at both ends of the second externally threaded fastener 138, and portions that may come into contact with the elastic member 116 are not externally threaded, so as to reduce friction between the elastic member 116 and the second externally threaded fastener 138.
