Abstract
The invention relates to a rear cover mechanism of a fuse cartridge specially used for a vacuum contactor-fuse protector combined electric device. The rear cover mechanism is characterized by comprising a rear cover formed by epoxy resin injection molding, a check block, a pull rod, a tongue piece, a shaft pin, a fuse, a micro switch, a preformed bolt hole, wherein the rear cover is cylinder shaped and is provided with raised pressure release groove on the edge, the rear cover is fixed at the rear part of the fuse cartridge of the combined electric device through the bolt hole, the fuse is connected with the tongue piece, the tongue piece is arranged on the shaft pin, one end of the tongue piece goes deep to the place below the check block and the other end of the tongue piece is connected with the fuse, the check block is connected with the pull rod and the pull rod is connected with the micro switch through a linkage mechanism. When the fuse is burnt out, the pressure release groove in the back cover can release high pressure gas so as to reduce pressure. The invention has the advantages of solving the insulation problem of one end of the fuse cartridge after the vacuum contactor-fuse protector combined electric device is assembled, and the back cover has large creepage distance, and high pressure resistance, and high mechanical strength, and light weight, and easy to install because of high standardization degree and high safety.
Description
Technical field
What the present invention relates to is the special-purpose molten tube of the vacuum contactor-fuse combined electric apparatus back lid mechanism that a kind of suitable High-Voltage Electrical Appliances are used.The design and fabrication technology field that belongs to medium voltage switchgear equipment.
Background technology
At present in the high-voltage electrical apparatus technical field, the used molten tube rear cover structure complexity of vacuum contactor-fuse combined electric apparatus, pull bar is regulated loaded down with trivial details, and fail safe is low, unenclosed construction, the overall dimension precision is low, the properties of product less stable, the degree of product standardization is low.
Summary of the invention
What the present invention proposed is the special-purpose molten tube of a kind of vacuum contactor-fuse combined electric apparatus back lid mechanism.Its purpose is intended to overcome the above-mentioned defective of existing in prior technology, can directly be disposed at withdrawable vacuum contactor-fuse combined electric apparatus.Product adopts the epoxy resin injection mo(u)lding, has the standardization level height, characteristics such as insulating properties height, safety, handled easily and maintenance behind the assembling bonnet.
Technical solution of the present invention: it is characterized in that comprising bonnet, block, pull bar, the tongue piece that adopts the epoxy resin injection mo(u)lding, pivot pin, fuse, sensitive switch, prepared screw-bolt hole, wherein bonnet is shaped as tubular, the gas pressure relief slot of marginal belt projection, bonnet is fixed on the molten tube of combined electrical apparatus rear portion by bolt hole, fuse and tongue piece link, tongue piece is on pivot pin, tongue piece one end gos deep into the block below, another termination fuse of tongue piece, block connects pull bar, and pull bar connects sensitive switch by link gear.Bonnet is shaped as tubular; the gas pressure relief slot of marginal belt projection; the bonnet prepared screw-bolt hole be convenient to combined electrical apparatus on molten tube fixing; reserve the pull bar through hole and can insert pull bar, pull bar can be up and down in through hole, and bonnet is fixed on the molten tube of combined electrical apparatus rear portion by bolt hole during work; to play insulating effect; after fuse blows, the gas pressure relief slot in the bonnet can gush gases at high pressure, plays a protective role.
Advantage of the present invention: product is simple and reliable, can rapidly impulsive force be passed to sensitive switch after fuse blows, no stuck or misoperation.Has the standardization level height, characteristics such as handled easily and maintenance; The product structure novelty, complete function, dimensional accuracy height; The epoxy resin Shooting Technique that adopts has improved the insulation property and the reliability of product greatly; Solved and be assembled into molten tube one an end Insulation Problems behind vacuum contactor-fuse combined electric apparatus, and the bonnet creepage distance is big, the withstand voltage properties height, the mechanical strength height, light weight, the standardization level height is easy to install, and is safe.
