Abstract
The utility model discloses a copper-aluminum transformer wire clamp comprising a supporting plate, a pressing plate and a welding plate, wherein the pressing plate and the supporting plate are connected by bolts, the supporting plate and the welding plate are connected, the supporting plate is provided with a wire trough, the pressing plate is arranged right above the wire trough, and the cross section of the pressing plate is U-shaped. The wire clamp further comprises a winding column arranged on the supporting plate, and the winding column is fixed to the axis of the wire trough. One end of a wire core entering the wire trough is connected to the winding column so as to ensure the stability of fixation of a cable in the wire clamp and reduce the influence of external factors to the cable. As the cross section of the pressing plate is U-shaped, a part, projecting downward, in the middle of the pressing plate can be directly in good contact with the wire core when the wire core enters the wire trough, pressure generated by the bolts when the bolts are screwed can be centered on the wire core, an overhead cable can be prevented from being loosened in the wire clamp due to swinging in wind, and the number of uncertain factors during work of the wire clamp is reduced.
Description
Technical field
The utility model relates to a kind of pole grasp type jockey of power transformer, specifically refers to copper aluminium transformer wire clamp.
Background technology
In field of power, device clamp rolls off the production line and is connected with the outlet terminal of electric equipment (as transformer, circuit breaker, instrument transformer, isolating switch, wall bushing etc.) for bus leading, the outlet terminal of now conventional electric equipment has copper and aluminium matter two classes, and lead-out wire mostly is aluminium stranded conductor or steel reinforced aluminium conductor, therefore device clamp is divided into again aluminum equipment wire clamp and two series of copper-aluminium transition equipment cable clamp; According to the installation and application of device clamp, be divided into screw bolt-type device clamp and compression-type device clamp.
At present the device clamp production technology of main flow is two kinds of friction welding (FW) and solderings, and friction welding (FW) belongs to butt welding, and the contact-making surface of copper aluminium welding is little, easily blows, and easily breaks under external force; Soldering is that copper sheet is welded in the one side that the whole and equipment of aluminium terminal main body contacts, the contact-making surface of welding is large, the time that aluminium is needed by copper oxidation (or corrosion) is long, with respect to friction welding (FW), more stablize, therefore, in electric power system, ban use of and adopt friction welding technological production equipment wire clamp.And still there is larger defect in device clamp on the market, as the transformer copper aluminum wire clamp of mentioning in file CN20110454188.9, built on stilts insulation cable is fixing rear as strong wind weather in metallic channel, cable easily produces larger swing, thereby the cable knob that causes being fixed in metallic channel produces loosening, when serious, cable can directly come off from device clamp, causes larger economic loss; And transformer copper aluminum wire clamp has been produced the shape size of rear entirety and can not have been changed, and under different installation environments, practicality is not high.
Utility model content
The purpose of this utility model is to provide copper aluminium transformer wire clamp, after facilitating cable to be connected and fixed, improves the stability that cable is fixed by wire clamp under various environment.
The purpose of this utility model is achieved through the following technical solutions:

Described supporting bracket is installed with screw rod on the end, one end near welded plate, and supporting bracket is threaded with welded plate by screw rod.Supporting bracket with welded plate for being threaded, by the internal thread arranging on the screw rod that arranges in supporting bracket and welded plate, can realize the spacing regulating between supporting bracket and welded plate, can control the length scale of the utility model global shape, to adapt to the connection of aerial cable between the shaft tower of model of the same race not, increased practicality.
The other end of described supporting bracket is also provided with stopper slot, and stopper slot is connected with metallic channel.Further, aerial cable is placed in metallic channel, is subject to still can produce the amplitude of oscillation after the impact of wind-force, affects the stability of wire clamp work; Stopper slot docks with metallic channel, and stopper slot is equivalent to the elongated end of metallic channel, can increase the length that cable is fixed in wire clamp, and then strengthens the steadiness of cable.
The bottom surface of described pressing plate is provided with anti-skid design.The frictional force when anti-skid design that pressing plate bottom surface arranges can increase pressing plate and contacts with core, avoids becoming flexible or coming off of core.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model copper aluminium transformer wire clamp, comprise supporting bracket, pressing plate and welded plate, pressing plate and supporting bracket are bolted, supporting bracket is connected with welded plate, in described supporting bracket, have metallic channel, pressing plate be arranged on metallic channel directly over, the cross section of described pressing plate is U-shaped, also comprise the winding stake being arranged in supporting bracket, be wound around stake and be fixed on the axis of metallic channel; The one end that enters the core of metallic channel is connected that to be wound around stake upper, to guarantee cable fixing stability in wire clamp, reduces the impact of extraneous factor on its generation; The cross section of pressing plate is U-shaped, in the time of in core enters into metallic channel, pressing plate middle part downwards outstanding part can directly contact with core well, the pressure concentration that while making to screw, bolt produces acts on core, avoid aerial cable in wire clamp, to produce when meeting wind swing loosening, the uncertain factor while reducing wire clamp work.
2, the utility model copper aluminium transformer wire clamp, supporting bracket with welded plate for being threaded, by the internal thread arranging on the screw rod that arranges in supporting bracket and welded plate, can control the length scale of the utility model global shape, to adapt to the connection of aerial cable between the shaft tower of model of the same race not, increased practicality;
