Embodiment Construction

[0009] see figure 1 , The names of the parts are as follows: epoxy resin tube insulating frame 1, universal wheel 2, silk screen 3, metal connection fixture 4.

[0010] see figure 1 , 66kV isolating switch V-shaped porcelain column fracture insulation protection frame includes a desktop insulation frame composed of epoxy resin tube 1, the main structure is simple, strong bearing capacity, the main body is made of epoxy resin tube insulation material, which can be decomposed for convenient storage and use. There are four universal wheels 2 at the bottom of the insulating frame 1, and there are silk screens 3 inclined on the surface of the insulating frame 1.

[0011] The protective frame is used in combination with two butt joints ( figure 1 The middle is a single one), forming a V-shaped mesh table top, which is easy to catch, and is connected with a metal connecting fixture 4 during docking, which is easy to fix.

[0012] The universal wheel 2 can support the whole insulat...

Abstract

The invention relates to a power transformation accessory of a power system, namely an insulation protection frame for preventing a V-shaped knob insulator of a 66kV isolating switch from cracking. The insulation protection frame comprises a desk insulation frame, wherein the desk insulation frame is composed of epoxy resin pipes, four universal wheels are arranged on the lower portion of the insulation frame, and a slanting silk net is arranged on the surface of the insulation frame. Two insulation protection frames are combined in a butt joint way in use to form a V-shaped netty desktop, and are connected with each other through a metal connection clamp during butt joint. The desk insulation frame composed of the epoxy resin insulation pipes is simple in the main body structure and strong in the bearing capability; a main body of the protection frame adopts epoxy resin insulation materials so that the main body of the protection frame can be decomposed, stored and used conveniently. The universal wheels can be used for conveniently controlling the protection frame to move in operation fields. The silk net is made of insulation materials through weaving. Two of the insulation protection frames for preventing the V-shaped knob insulator of the 66kV isolating switch from cracking are in joint connection during use and are connected through the metal connection clamp.

Description

technical field [0001] The invention relates to a substation accessory of a power system, that is, an insulation protection frame for breaking a V-shaped porcelain column of a 66kV isolating switch. Background technique [0002] At present, there are still a certain number of 66kV isolating switches with V-shaped ceramic columns in the operating substation. Because this kind of switch has been in operation for a long time and the porcelain pillars are aging, many V-shaped porcelain pillars have broken, which poses a great threat to people and equipment. In order to ensure that the staff will not be threatened by the fracture of the V-shaped porcelain column during normal operations, the "insulation protection frame for the fracture of the V-shaped porcelain column of the 66kV disconnector switch" has been developed. Contents of the invention [0003] The object of the present invention is to provide an insulating protective frame for breaking the V-shaped porcelain pillar...
