Abstract
The utility model relates to an embedded type insulated casing tube comprising an inner casing tube, an outer casing tube and a spacer layer. The inner casing tube is matched with the outer casing tube; one end of the inner casing tube is inserted into one end of the outer casing tube; and the spacer layer is arranged between the inner casing tube and the outer casing tube, wherein the spacer layer that is used as the thermal insulating layer can be air or can be formed by filling of fireproof materials. An internal space is formed inside the inner casing tube and the outer casing tube through the spacer layer; and a wiring terminal assembly and an outgoing cable head are arranged inside the space, so that the wiring terminal assembly and the outgoing cable head can work under the protection of the insulated casing tube. Physical dimension designing is carried out on the specifications of the inner casing tube and the outer casing tube according to the working voltage and the working current of an electric heating wire, which needs to be led out, of an electric energy storage furnace. Moreover, the provided embedded type insulated casing tube has characteristics of small volume, easy processing, convenient installation, and reliable insulation and security properties.
Description
Technical field
The utility model relates to a kind of inserted insulating sleeve, relates in particular to a kind of insulating sleeve of drawing termination for 10-66 kilovolt electric heating energy-storage stove high pressure.
Background technology
At present, the leading-out terminal of the electrical heating wire of 10-66 kilovoltage grade electric heating energy-storage stove generally adopts the wall bushing of electric power system routine to replace.The problem of its existence is: be arranged on and will leave around two terminals of wall bushing on the electric heating energy-storage stove heat-insulation layer wall greater than the interval of arcing distance and configure the high-tension cable junction box, institute is so that electrical heating wire is drawn the termination volume is not easy to more greatly install.Patent application " electric heating energy-storage stove high pressure is drawn termination ", although can address this problem, because sleeve pipe is overall structure, casing length is long, and difficulty of processing is very large, and the adjusting of heat-insulation layer is inconvenient in using, and stress is excessive, easily fracture.
Summary of the invention
The utility model provides a kind of handling ease, flexible inserted insulating sleeve flexible, easy to use for the problem of above-mentioned existence, this insulating sleeve is installed on the heat-insulation layer of electric heating energy-storage stove, and heat-insulation layer inner high voltage electrical heating wire exit is drawn.Draw the insulation property of terminals for improving electric heating energy-storage stove electrical heating wire, place insulating sleeve inside that the terminal electrified body is worked under the protection of insulating sleeve this binding post, simplified wiring construction and improved the equipment reliability of operation.
The technical solution of the utility model is as follows:
A kind of inserted insulating sleeve; it is characterized in that: it is comprised of inner sleeve, outer tube and thermal insulation layer; inner sleeve and outer tube coupling arrange; one end of inner sleeve is inserted in the end of outer tube; be provided with wall between inner sleeve and the outer tube; this wall can be that air also can filling fire resisting material as thermal insulation layer; inner sleeve and outer tube inside are by inlaying the inner space of formation; connecting terminal components and outgoing cable head are arranged in this space, make it carry out work under the protection of insulating sleeve.
Described inner sleeve and outer tube are the elongate tubular structure that the electroceramics material is made, and its specification is carried out the physical dimension design according to operating voltage and the operating current of the electrical heating wire that electric heating energy-storage stove needs are drawn.
Advantage of the present utility model is as follows:
The utility model because adopt the inner sleeve of porcelain insulation and outer tube as mounting structure, connecting terminal components and outgoing cable head are all established its inside, effectively solve prior art and adopted wall bushing, joint-box need to be set, cause equipment volume huge, to the problem that installation is made troubles, the insulation property that electric heating energy-storage stove electrical heating wire is drawn terminals have been improved.And, handling ease, internal and external casing is flexibly flexible, and heat-insulation layer is convenient in the use regulates, not easy fracture.Because binding post places inside and outside inside pipe casing, the terminal electrified body is worked under the protection of insulating sleeve, has simplified wiring construction and has improved the equipment reliability of operation.Have that volume is little, the characteristics of handling ease, easy for installation, insulation safety dependable performance.
