Abstract
The utility model relates to a bended type sleeve of a solid insulation totally-enclosed switch, comprising a conductive core and an epoxy resin insulating layer, wherein the conductive core is a cylindrical copper rod bended by 90 DEG, one end of the cylindrical copper rod is provided with a cable connecting hole, the other end of the cylindrical copper rod is pressed to be a copper sheet, the epoxy resin insulating layer covers the outer side of the copper rod, the epoxy resin insulating layer between the cable connecting hole and the 90 DEG bended corner is provided with a small boss, the small boss is provided with a copper embedded member vertical to the cable connecting hole, one end of the copper embedded member closer to the cylindrical copper rod is provided with a semiconductor shielding layer, and a gap is formed between the semiconductor shielding layer and the cylindrical copper rod. Advantages of the bending type sleeve are that electrical performance is excellent, insulation level is high, electric field distribution is uniform, no current sound exists in operation, various natural environments can be adapted to, and work life is long. Besides, the bended type sleeve is provided with the shielding layer.
Description
Technical field
The present invention relates to the curved formula sleeve pipe of a kind of solid fully-closed switch insulation, it is used for stube cable in the power transmission and distribution cabinet, can be as inlet wire, the outlet use of cabinet with cable.
Technical background
Along with the development of electric power, telecommunications industry, generally adopt plastic tube to bury underground cable, optical cable underground at present, but owing to manufacturer relatively payes attention to the main part product, and accessories such as connector are lacked enough improvement designs.Therefore, also rest on simple tubular style structure, particularly cable tube to the connector of cable, optical cable and bury underground when changing direction, the connection of its corner does not have desirable solution so far as yet.
Summary of the invention
The goal of the invention of the utility model is to solve existing cable, optical cable does not have the crooked problem that connects, and provides a kind of solid fully-closed switch insulation to bend the formula sleeve pipe.
In order to accomplish the goal of the invention of the utility model, the utility model adopts following technical scheme:
A kind of solid fully-closed switch insulation of the utility model is bent the formula sleeve pipe; It comprises: conductive cores and epoxy resins insulation layer, and wherein: conductive cores is crooked 90 ° a cylindrical copper rod, has the cable connecting hole at an end of cylindrical copper rod; Copper rod at the other end of cylindrical copper rod is pressed into copper sheet; The epoxy resins insulation layer is coated on the outside of copper rod, on the epoxy resins insulation layer between 90 ° of bendings of the cable connecting hole of copper rod and copper rod, a small boss is arranged, and the copper insert vertical with the cable connecting hole is housed in small boss; Copper insert near cylindrical copper rod one end the shield semiconductors layer is housed, shield semiconductors layer and cylindrical copper rod have a gap;
A kind of solid fully-closed switch insulation of the utility model is bent the formula sleeve pipe, and wherein: described shield semiconductors layer is the annular semiconductor screen around one section cylindrical copper rod outside;
A kind of solid fully-closed switch insulation of the utility model is bent the formula sleeve pipe, wherein: a big boss is arranged on the epoxy resins insulation layer near copper sheet;
A kind of solid fully-closed switch insulation of the utility model is bent the formula sleeve pipe, and wherein: described big boss is a rectangle boss.
The present invention is adopted as epoxy resin APG operation pressure gel forming technology.Sleeve pipe comprises that 99% high-purity copper conductive cores, conductive cores outer wrap epoxy resins insulation layer, epoxy resins insulation layer centre are linked by shield semiconductors layer, semiconductive shielding layer and copper insert and form.It is applicable to that rated voltage is in the 12KV switchgear.
The curved formula sleeve pipe of the solid fully-closed switch insulation of the utility model is compared with existing like product, has the following advantages:
1. the utility model adopts the APG technical matters.Meet GB, IEC standard.
2. electric property is superior.Insulation level is high, has the insulating capacity that tolerates under industrial frequency withstand voltage, impulse withstand voltage and the long-term rated voltage.
3. Electric Field Distribution is even.Interior provided with shielding layer, even, the in service no current sound of Electric Field Distribution, office puts less than 5pC.
4. convenient succinct female cabinet that joins of realizing.The curved formula design of the present invention's employing rational in infrastructure utilizes a kind of straight edge line and gumshoe to be easy to realize female requirement that joins cabinet through preceding outlet, back outlet, following outlet.
5. it is succinct convenient to install.Can realize user's objective requirement.Sleeve pipe of the present invention can have the mounting condition of both direction can easily realize preceding outlet of cabinet and back outlet.
6. non-maintaining.Curved formula sleeve pipe resistant is dirty and moist, need not special maintenance.
7. can adapt to various natural environments.Under the abominable natural conditions of environment, move, can keep enough intensity and mechanical shock performances.
8. long working life.Good heat aging performance can guarantee the life-span more than 20 years
The like product weak point
Mostly like product is straight formula structure, installs constantly, and the user is not easy to realize the female scheme that joins cabinet of switch.
