Abstract
The utility model relates to a high-voltage lead-out wiring device for an electric heating energy storage furnace, which adopts an electrical porcelain insulating sheath mounted on a heat preservation layer as a mounting structure, wiring terminal assemblies and a lead-out cable head are mounted in the electrical porcelain insulating sheath so as to enable the terminal assemblies and the lead-out cable head to operate under the protection of the insulating sheath; an annular boss is formed on an internal wall of the electrical porcelain insulating sheath; an electrode thermal insulation base is mounted on the end face of the boss; the insulating sheath placed in a high temperature area is provided with an electric heating wire lead bank and then filled with heat preservation media for heat insulation; a cable positioner is fixed at the side end of an external heat preservation layer of the electrical porcelain insulating sheath and provided with heat dissipation holes to allow the internal temperature of the insulating sheath placed on the external thermal insulation layer side to be lower than the maximum service temperature of a cable; and the length from the annular boss of the internal wall of the electrical porcelain insulating sheath to the insulating sheath on the external thermal insulation layer side is required to be greater than that of a single-core high-voltage insulating cable head to allow the cable exposed from the cable positioner to keep a good original appearance. The high-voltage lead-out wiring device has the characteristics of small size, convenience in mounting, economy and practicability, and reliable insulation safety performance.
Description
Technical field
The utility model relates to a kind of electric heating energy-storage stove high pressure and draws termination, relates in particular to a kind of 10-66 kilovolt electric heating energy-storage stove electrical heating wire and draws termination.
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 dispose 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.
Summary of the invention
The utility model is for the problem of above-mentioned existence and provide a kind of electric heating energy-storage stove high pressure economical and practical, easy to use to draw termination, and this device is installed on the heat-insulation layer of electric heating energy-storage stove 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 electric heating energy-storage stove high pressure is drawn termination, it is characterized in that: it is comprised of porcelain insulation sheath and high-voltage terminal sub-component, the porcelain insulation sheath is installed on the heat-insulation layer, and it is inner that connecting terminal components and outgoing cable head part are installed in the porcelain insulation sheath; The porcelain insulation jacket inner wall is provided with annular boss, and the adiabatic base of the end face installing electrodes of boss, the insulating sleeve that is placed on the high-temperature region are partly installed behind the heating wire lead stuffed heat insulated with thermal insulation medium; Cable locators is fixed on porcelain insulation sheath external thermal insulation side end and leaves louvre and makes the insulating sleeve partial interior temperature that is placed on the external thermal insulation side be lower than the cable maximum operation (service) temperature.
Described high-voltage terminal sub-component is comprised of heating wire lead, punching electrode, clamp nut, the adiabatic base of electrode, cable tail nose, cable locators, thermal insulation medium, single core high voltage insulation cable head.
The specification of described porcelain insulation sheath designs physical dimension according to operating voltage and the operating current of the electrical heating wire that electric heating energy-storage stove needs are drawn.
Described porcelain insulation jacket inner wall annular boss is slightly larger than single core high voltage insulation cable head length to the insulating sleeve length of external thermal insulation side makes the cable that exposes beyond the cable locators keep original appearance intact.
Advantage of the present utility model is as follows:
The utility model electric heating energy-storage stove high pressure is drawn termination owing to adopt the porcelain insulation sheath 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.This device places insulating sleeve inside that the terminal electrified body is worked under the protection of insulating sleeve binding post, has simplified wiring construction and has improved the equipment reliability of operation.Have that volume is little, easy for installation, economical and practical, the characteristics of insulation safety dependable performance.
