Abstract
The utility model relates to a fastener for a high-voltage heavy-current electric contact. The electric systems all know that the overheating problem of the fastener for the electric contact leads to various major accidents and the overheating of the contact during power supply causes reactive loss and waste of electric power. In order to overcome the deficiencies, the utility model provides a special fastener for a non-overheated electric contact, so as to realize no overheating of the contact connecting piece during high-voltage heavy-current operation, effective solving of major accidents and reactive loss which are caused by contact overheating during power supply, reduction of the power supply cost, safety, reliability and power conservation. A hexagonal head is designed to enlarge and thicken the head of a bolt, thread is formed on a screw rod at the other end of the bolt head provided with an inverted internal taper at the matching surface end between the bolt head and the fastener, the screw rod penetrates a thin gasket and a screw rod for the hole on an electric lead wire head connecting plate, is inserted into the thin gasket and is connected with a hexagonal nut provided with fastening function and enlarged and thickened inverted internal tapers on the two end surfaces and an ordinary standard part nut provided with locking function.
Description
Technical field
The utility model relates to a kind of high pressure, large-current electric gas contact securing member.
Background technology
Electric power system is known, perplexs electric power always and connects that the overheated reactive loss that causes of contact has strengthened power supply cost to waste of electric energy in various major accidents that contact securing member problems of excessive heat causes and the powered operation.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of only thermoelectric gas contact special fastener just can reach not overheated safe and reliable at high pressure, big current lead-through contact in service, effectively solves reactive loss in the powered operation, reduces power supply cost, economize on electricity.
The technical scheme in the invention for solving the technical problem is: by strengthening the thickening both ends of the surface six-sided nut of internal taper face is arranged, strengthen thickening hexagon bolt head and bolt head and fastener mating surface end, the bolt that the internal taper face is arranged, the only thermoelectric gas contact special fastener that the thin type packing ring is formed, it is characterized in that: hexagonal head strengthens the thickening bolt head, bolt head and securing member mating surface end have the other end screw rod of the bolt head of internal taper that screw thread is arranged, screw rod passes the thin type packing ring, electrical wire head connecting plate, on the screw rod in hole, be inserted in the thin type packing ring and have the increasing of fastening effect to thicken the six-sided nut that both ends of the surface have internal taper, and there is the common standard part nut of the anti-loosening effect of locking to connect, bolt, nut, packing ring is structure carbon steel, and surface treatment is zinc-plated.
The beneficial effects of the utility model are: simple in structure, do not change original electrical structure and install, solved the high pressure that power supply system perplexs always, the overheated various major accidents that cause of large-current electric gas contact securing member, and in powered operation owing to be fastenedly connected the overheated reactive loss that causes of wire contact, effectively reduced power supply cost and reached the economize on electricity purpose of safety.
