Abstract
The invention relates to a support composite insulator for an isolating switch and filled with solid insulating media. The support composite insulator comprises an insulating pipe (1), end assembling members (3) and a silicon rubber umbrella skirt (4), wherein the end assembling members (3) are respectively and fixedly stuck at two ends of the insulating pipe (1), and the silicon rubber umbrella skirt (4) is arranged on the outer side of the insulating pipe (1). The support composite insulator is characterized in that a solid insulating medium (2) is filled in the insulating pipe, and the silicon rubber umbrella skirt (4) of an integral structure is fixedly stuck on the outside of the insulating pipe. The support composite insulator has the advantages of being excellent in pollution flashover and rain flash resistance and free of washing after operation, needing small amount of maintenance, and being particularly suitable for areas severe in pollution; being good in rigidity, greatly improving mechanical performance, and according with using requirements of isolating switch devices; and reducing production cost and shorting production cycle.
Description
Technical field
The present invention relates to a kind of inner isolating switch post composite insulator of filling solid dielectric insulation, be mainly used on the high voltage isolator equipment in the electric power system.
Background technology
Composite insulator has been widely used in the electric power system, but the use on high voltage isolator equipment also comes with some shortcomings.Wherein, topmost problem is that post composite insulator top under stressing conditions can produce larger side-play amount, has influence on the normal divide-shut brake of isolating switch.So the post composite insulator that uses on the high voltage isolator must have higher mechanical property and insulation characterisitic.
What high voltage isolator generally used at present is true procelain post insulator, solid strut composite insulator, hollow inflatable formula post composite insulator and porcelain core post composite insulator.Wherein true procelain post insulator Heavy Weight transports inconvenience is installed, and in running fracture of root and pollution flashover accident occurs easily; The solid strut composite insulator adopts the glass-epoxy leading-drawing rod to support and interior insulation as its skeleton, and owing to the glass-epoxy material has toughness, the strain under stressed is larger, can not satisfy the instructions for use of isolated switchgear; Hollow inflatable formula post composite insulator adopts hollow insulated tube to do column, inner blanketing gas insulate, because gas filler is prone to leakage, thus must fill supervising device with the variation of monitoring interiors of products gas, but also have certain potential safety hazard; Its manufacture method of porcelain core composite post insulator is that the full skirt that the silicon rubber synthetic material is made is bonded on the porcelain core, because porcelain core is processed into without precision optical machinery, the concavo-convex silicon rubber full skirt that easily causes that presents on its surface microscopic is bonding not firm, produce the phenomenons such as bubble, affect electric property and the life-span of product.
Summary of the invention
The purpose of this invention is to provide a kind of inner isolating switch post composite insulator of filling solid dielectric insulation, the above-mentioned variety of issue that exists to solve prior art.
For achieving the above object, the present invention adopts following technical scheme: a kind of inner isolating switch post composite insulator of filling solid dielectric insulation, comprise insulated tube, end fittings and silicon rubber full skirt, end fittings cements in respectively the two ends of insulated tube, is provided with the silicon rubber full skirt in the outside of insulated tube.Wherein, be filled with a kind of solid dielectric insulation in the inside of described insulated tube, at the integrally-built silicon rubber umbrella of the outside cementation one deck body of insulated tube.
Technical scheme of the present invention is:
The present invention compared with prior art has following distinguishing feature:
1, post composite insulator proposed by the invention is compared with porcelain strut insulator with existing isolating switch, the excellent performances such as resistant sudden strain of a muscle, rain sudden strain of a muscle, and exempt from after the operation to clean, the few maintenance is particluarly suitable for filthy serious area and uses.
2, post composite insulator proposed by the invention is compared with the solid strut composite insulator with existing isolating switch, and good rigidly has improved the mechanical performance of insulator greatly, more meets the instructions for use of isolated switchgear.Reduce production cost, shortened the production cycle.
