Abstract
The utility model relates to a short circuit hardware in a power grid ice melting system. Compression annular tubes on two ends of a short circuit lead are connected with a tubular bus T type wire clamp and a lead T type wire clamp. One end of a wire clamp body of the bus and the lead T type wire clamps passes through a hinge pin and one end passes through a rapid locking device so as to form an integral structure which can be opened and closed with a cover plate. A locking anti-loosing damping pad is in the rapid locking device so as to form an eccentric-cam damping-type rapid locking device. The tubular bus and the lead T type wire clamp bodies of the utility model are connected with the cover plate through using the hinge pin. Opening and closing end fastening adopts the eccentric-cam damping-type rapid locking device. The structure is reasonable. Disassembly and assembly are flexible. Ice melting operation time is short. Working efficiency is high. The hardware is suitable for mobile installation. A need of the short circuit of the power grid ice melting system can be completely satisfied. The compression annular tube of the tubular bus T type wire clamp, the compression annular tube of the lead T type wire clamp and the short circuit lead are made through using a hydraulic compaction mode. A short circuit problem of the ice melting system and the power grid is effectively solved. Line impedance matching and system switching operations are inexistent.
Description
Technical field
The utility model relates to the short circuit gold utensil in a kind of electrical network ice melting system.
Background technology
Transmission line is when running into the extreme climates such as low temperature sleet and snow ice, power transformating and supplying facility and wire can constantly be assembled ice and snow, will cause line tripping when institute icing snow acquires a certain degree, when serious even can cause circuit to break and the phenomenon of falling the tower, do great damage to electric power facility.The electrical network ice melting system is to solve an extreme climate electrical network icing difficult problem, improves the important safety safeguards system of transmission line opposing low temperature sleet and snow ice natural calamity ability.The electrical network ice melting system of at present practical application is to be made of complete multisplit wire and mobile rectifying conversion device two large divisions, under the normal climate condition, the electrical network ice melting system is the autonomous system of separating with grid cut-off, only when processing the power network line icing, just with the short circuit mode mobile rectifying conversion device is accessed electrical network, carry out the ice-melt operation.Existing line short circuit implementation is that a MTLY type pipe capital tool and the soft bus-bar T-shaped wire clamp of TLY type are coupled together with wire, this connection mainly is comprised of bolt and hydraulic pressure sleeve pipe, installation and removal is all very loaded down with trivial details, operating efficiency is low, artificial crimping is unstable, contact resistance is large, security reliability is poor, is not suitable for the movement of rectifying conversion device and flexible characteristics such as use.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of rational in infrastructurely, easy for installation, does not affect the short circuit gold utensil in switching performance, the safe and reliable electrical network ice melting system.
The implementation of the utility model purpose is, short circuit gold utensil in the electrical network ice melting system, the compression sleeve tube connector bus-bar T-shaped wire clamp at short circuit wire two ends and the T-shaped wire clamp of wire, wire clip body one end of bus-bar T-shaped wire clamp, the T-shaped wire clamp of wire passes through hinge pin, one end by quick-locking device and cover plate form can folding overall structure, the locking damping mat of locking is arranged in the quick-locking device, form eccentric cam damp type quick-locking device.
The utility model makes the form that body and the cover plate of traditional pipe bus-bar T-shaped wire clamp and the T-shaped wire clamp of wire connects in the bolt mode to connect with bearing pin into, the fastening employing eccentric cam of folding end damp type quick-locking device, rational in infrastructure, dismounting is flexible, shortened the ice-melt operating time, improved the ice-melt operating efficiency, be fit to mobile the installation, can satisfy the needs of electrical network ice melting system short circuit fully.Icing characteristics according to the electrical network extreme climate, pipe bus-bar T-shaped wire clamp compression sleeve and the T-shaped wire clamp compression sleeve of wire adopt the hydraulic compression mode to make the novel ice melting system of cover short circuit gold utensil with the short circuit wire respectively, efficiently solve the short circuit problem of ice melting system and electrical network, avoided traditional approach ice-melt required line impedance coupling and numerous and diverse system's grid switching operation.
The utility model is rational in infrastructure, easy for installation, does not affect switching performance, safe and reliable.
