Description

Multidirectional adjustable sliding support structure and support method Technical Field The invention relates to the technical field of electrical equipment, in particular to a multidirectional adjustable sliding support structure and a support method. Background The gas-insulated metal-enclosed combined electric appliance (GIS) is characterized by that several high-voltage electric appliances of circuit breaker, isolating switch, grounding switch, bus bar and mutual inductor are integrated and sealed in the grounded metal shell, and charged with a certain pressureThe complete switch equipment formed by taking gas as an insulating medium has the advantages of large power transmission capacity, small occupied area, simple maintenance, long service life and the like, and each assembled combined electrical appliance is called as a space. In conventional GIS installation, bolts are typically used to make the rigid connection between the spaced buss and the buss, and between the buss support and the mounting support. If the GIS interval is longer, the thermal expansion and contraction deformation of the bus barrel caused by the change of the external temperature can be large, and the generated huge stress can cause the extrusion deformation of the bus barrel, so that the reliable operation of equipment is affected, and equipment faults are easily caused. So that it is supported between the spaced bus bar barrels and the bus bar barrels. The original support can only be adjusted up and down by using the double-end full-wire screw rod in the installation process, the height can not be adjusted by itself after being fixed according to the design, and the original support can not be changed left and right, front and back and up and down along with the settlement deformation of a foundation due to thermal expansion and cold contraction of a product, and the bus barrel shell is affected after a long time, so that the hidden danger of air leakage is caused. In summary, the prior art has the disadvantage that the existing adjusting function is limited to an initial height calibration at the installation stage, and the support structure forms a rigid connection once the installation is completed and secured by the nut lock. In the subsequent long-term operation process of the equipment, when the bus cylinder generates deformation stress due to factors such as thermal expansion and contraction, uneven settlement of a foundation, vibration of the equipment and the like, the existing rigid support cannot adaptively deform or slide along with the bus cylinder, so that the compensation capability is lost, the deformation stress accumulated for a long time is easy to cause the extrusion deformation of the bus cylinder, and the hidden danger of air leakage exists. Disclosure of Invention Aiming at the defects existing in the prior art, the invention provides the multidirectional adjustable sliding support structure and the supporting method, which can weaken the influence of environment, foundation settlement and installation errors on the combined electrical appliance, improve the product quality, effectively reduce the hidden danger of air leakage and meet the requirement of long-time safe and reliable operation of the combined electrical appliance.
