The wire clamp used for the high-voltage equipment is advantageous in favorable mechanical property, reliably in connection with high-voltage primary equipment and transmission lines, higher fracture-resistance performance, fast and convenient installation, effective prevention of wire clamp fracture and transmission line safety accidents, greatly saved repair cost as well as broad prospect and practical significance in power systems. The wire clamp used for the high-voltage equipment of the utility model is suitable for being used for high voltage transmission line wiring terminals.
Description
Technical field
The utility model relates to a kind of high voltage installation wire clamp, belongs to high voltage power transmission and transformation equipment technology field.
Background technology
In high voltage installation connected, when copper, aluminium conductor directly connected, the contact-making surface of these two kinds of metals very easily made aluminium produce electrochemical corrosion under the effect of moisture in air, carbon dioxide and other impurity, caused the contact resistance of copper, aluminium junction to increase.Thermal coefficient of expansion and the modulus of elasticity of adding copper, aluminium differ greatly, and are in operation can cause the contact point excess Temperature even the accident such as can smolder, burn.Therefore for making stable connection between electric equipment, reduce contact resistance, strengthen electric conductivity, need to carry out excessive soldering to copper aluminium bi-material with wire clamp of copper-aluminum apparatus and connect.Be copper material and the traditional copper aluminum equipment wire clamp is an end, the other end is aluminum material.Cross section contact by bi-material between the copper aluminium connects.The traditional copper aluminum equipment wire clamp has in use been found more problem, and loose contact, crack conditions often appear in copper aluminium junction, affects power supply quality, causes circuit, the platform district stops transport, and affects power supply reliability.
The high voltage installation wire clamp is requisite vitals in the electrical network, in the important repair and maintenance equipment technology of ultra-high-tension power transmission line field, it is the important leverage of electric line safety in production that the defence line pinch off splits, and its safe operation is directly connected to the safety and stability of electrical network and to the reliability of customer power supply.Facts have proved that the only safe and reliable connection of secure transmission line vitals just can reach the purpose of safe distribution of water electricity, can prevent that the pernicious power-off event of large tracts of land from occuring.
The high voltage installation wire clamp is anti-fracture to be the important process that ensures that electric power transmission ﹠ distribution process safety is produced.Do not improve wire clamp with other and compare, this high voltage installation wire clamp has following characteristics: 1. the high voltage installation wire clamp carries out the transition connection by copper, aluminium bi-material, and transition face is zigzag, can play anti-fracture effect; 2. installation method is simple, rapid.
Summary of the invention
The purpose of this utility model is to cause the transmission line fluctuation of service, the large area blackout of initiation, the safety in production of guarantee high pressure transmission and distribution network in order effectively to prevent high-voltage transmission equipment with the wire clamp fracture; Reduce contact resistance, promoted ultra-high-tension power transmission line delivery of electrical energy efficient; The utility model discloses a kind of high voltage installation wire clamp.
The technical solution of the utility model is, the utility model high voltage installation is inserted by the band wire clamp terminal block of aluminum and terminal block copper with wire clamp and is formed, be the wire clamp of attached cable copper cash with wire clamp terminal block one end, in addition upper end with the wire clamp terminal block is terminal block, the terminal block bottom has can be for " " shape cascaded surface of inserting, and its ladder plane is zigzag; It is the block body of a rectangle that terminal block copper is inserted, and its thickness is consistent with the ladder height of terminal block bottom, and its rectangle simultaneously is zigzag, and another side is the plane; The ladder serrated face of the serrated face that terminal block copper is inserted and terminal block bottom coincide, and is welded by soldering, terminal block copper is inserted be connected as a single entity with terminal block with wire clamp.
The utility model utilizes the zigzag interface of special construction distribute to consist of the anti-fracture wire clamp of copper aluminium, and the band wire clamp terminal block that uses soldering processes that terminal block copper is inserted with aluminum is welded as a whole.Improve its stress and realize the anti-fracture function of transmission line wire clamp.Soldering processes are to adopt to make solder than the low-melting metal material of base metals, weldment and solder are heated to above the solder fusing point, be lower than the mother metal fusion temperature, utilize liquid solder to infiltrate mother metal, fill the interface gap and mutually diffuse to form the method for the firm weldment that is connected with mother metal.Use soldering processes to have less contact resistance, promoted ultra-high-tension power transmission line delivery of electrical energy efficient.Installation method is simple, rapid.
The beneficial effects of the utility model are: increased copper aluminium contact area, reduced contact resistance, promoted ultra-high-tension power transmission line delivery of electrical energy efficient.Can effectively prevent the pernicious power outage of large tracts of land because of the initiation of wire clamp cracking, improve electrical network power transmission and distribution safety in production level and ensure electrical network power transmission and distribution safety.Because this wire clamp has good mechanical performance, can connect reliably high voltage primary equipment and transmission line, and have higher anti-fracture performance, the characteristics such as convenience quick for installation, can prevent well the wire clamp fracture, prevention transmission line security incident occurs, and saves a large amount of maintenance costs.Widely promotion prospect and the actual meaning of using are arranged in network system.
The utility model is fit to the ultra-high-tension power transmission line terminals to be used.

Embodiment
The utility model embodiment as depicted in figs. 1 and 2.
The present embodiment high voltage installation is inserted by the band wire clamp terminal block 1 of aluminum and terminal block copper with wire clamp and 2 is formed, end with wire clamp terminal block 1 is the wire clamp of attached cable copper cash, in addition upper end with wire clamp terminal block 1 is terminal block, the terminal block bottom has can be for " " shape cascaded surface of inserting, and its ladder plane is zigzag; It 2 is the block bodies of a rectangle that terminal block copper is inserted, and its thickness is consistent with the ladder height of terminal block bottom, and its rectangle simultaneously is zigzag, and another side is the plane; Insert 2 serrated face of terminal block copper coincide with ladder serrated face with wire clamp terminal block 1 bottom, and is welded by soldering, terminal block copper is inserted 2 be connected as a single entity with terminal block 1 with wire clamp.
The present embodiment high voltage installation is in use holed at band wire clamp terminal block as required with wire clamp, is used for reliable fixing clamper.Because terminal block partly is to be inlayed mutually and connect with soldering with copper coin by aluminium sheet, has higher mechanical strength and less contact resistance, the reduction of favourable high voltage transmission line line loss.
