Embodiment Construction

[0022] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0023] The housing of the high-insulation linear isolating switch shown in the accompanying drawings includes a main cylinder 2, two main cylinder flanges 1, two reducing cylinders 4, and four support cylinder assemblies 3 (in other embodiments, there are 2-3 or more than 4 support tube assemblies 3); the side wall of the main tube 2 has 4 holes (in other embodiments, there are 2-3 or more than 4 holes), and the orifice extends outward to form 4 support Tube I2.1 (in other embodiments, there are 2-3 or more than four support tubes I2.1), the intersection of main tube 2 and support tube I2.1 is smoothly connected by an arc; The end is welded and fixedly connected to the main cylinder 2, and the small end is fixedly welded to the main cylinder flange 1; the support tube assembly 3 is composed of the support tube II 3.1 and the support tub...

Abstract

The invention discloses a high-insulation linear disconnecting switch casing which comprises a main cylinder, a main cylinder flange, a diameter variable cylinder and branch cylinder assemblies; eachbranch cylinder assembly is composed of a second branch cylinder and a branch cylinder flange, and each second branch cylinder is welded and fixedly connected to a corresponding first branch cylinderin the side surface of the main cylinder; the outward end surfaces of the main cylinder flange and the branch cylinder flanges are concaved to form first and second grooves respectively; further, holes are formed in the sidewall of the main cylinder, the holes extend outwardly to form the first branch cylinders respectively, and the position where the main cylinder is intersected with the first branch cylinders are in arched smooth connection; the minimal distance L1 between flanges of the adjacent first branch cylinders is greater than or equivalent to 7t (t represents the wall thickness of the main cylinder); the minimal distance L2 between the flange of the first cylinder and the end surface of the main cylinder is greater than or equivalent to 5t; and the hole walls in the main cylinder, the main cylinder flange, the diameter variable cylinder and the branch cylinder assemblies are coated with insulating coatings respectively. Thus, the sealing surfaces of the outward end surfacesof the main and branch cylinder branches are protected effectively, welding deformation is low, a discharging phenomenon does not occur, the insulating performance is high, and use is safe and reliable.

Description

technical field [0001] The invention relates to the field of high-voltage substations, in particular to a linear isolating switch housing. Background technique [0002] The existing linear isolating switch shell includes a main cylinder, two main cylinder flanges, two reducing cylinders, and several supporting cylinder components. The large end of the reducing cylinder is welded and fixedly connected to the main cylinder, and the small end is connected to the main cylinder flange Fixed welding connection. The support tube assembly is composed of support tube II and support tube flange. The support tube II is welded and fixedly connected with the support tube I on the side of the main tube. Sealing surface. When in use, the sealing ring is in close contact with the flange of the main cylinder and the outward end face of the flange of the support cylinder assembly to form a sealing structure. The sealing structure of the housing of this linear isolating switch is simple, but...
