Description

technical field

The utility model relates to an improvement of a heat-generating and diverting device of a wire drainage plate, in particular to a heat-generating and diverting device of a strain-clamp diversion plate suitable for transmission lines.

Background technique

With the expansion of the grid scale and the continuous improvement of the importance of electric energy to people's life, the society has higher and higher requirements for the reliability of power supply. The transmission line is an important part of the power system, and its reliability plays an important role in the safe and stable operation of the entire power system. The heating problem of the strain clamp drainage plate is an important factor affecting the safe and stable operation of the transmission line. The heating of the strain clamp drain plate is caused by the thermal effect of the current. The strain clamp drain plate itself has a certain resistance. When the current passes, a part of the electric energy must be lost, so that the temperature of the strain clamp drain plate rises. Under normal circumstances, the contact resistance of the drainage plate of the tension clamp is very small, and its heat generation will not be higher than that of the adjacent current-carrying wires. The contact resistance of the wire clamp drain plate increases, which in turn causes the strain clamp drain plate to heat up. When the strain-clamp drainage plate heats up, the metal oxidation will be accelerated, and the contact resistance will be greater, forming a vicious circle. In severe cases, the drainage will be heated and blown out, which poses a great threat to the safe and stable operation of the power grid.

It can be seen from the search that in order to overcome the above deficiencies in the prior art, Chinese patent 201420016717.0 discloses a "wire drainage plate heating shunt processing device", which includes two drainage plates and two wires connected to them, and hooks between the two wires. Hang up the shunt mechanism, and this "wire drainage plate heating shunt processing device" is not suitable for the strain clamp drainage board of the transmission line.

Contents of the invention

The purpose of this utility model is to provide a method of reducing the current intensity flowing through the strain clamp drain plate by connecting a drain wire with a small resistance at both ends of the strain clamp drain plate in parallel, thereby reducing the tension of the strain clamp drain plate. The calorific value is specially used for the heat distribution device of the tension clamp drainage plate of the transmission line.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the heating and shunting device of the tension clamp drainage plate includes the tension clamp drainage plate, one end of the tension clamp drainage plate is connected with the drainage wire, and the tension wire The other end of the clamp drainage plate is connected to the insulator, and it is characterized in that: one end of the tension clamp drainage plate connected to the drainage wire is provided with a conductor clip; the handle end of the tension clamp drainage plate is provided with a drainage plate handle clip; Connect with a shunt wire between the conductor clip and the handle clip of the drain plate.

The utility model is also implemented through the following measures: the conductor clamp is composed of an arc-shaped splint, a flat splint, a fixing bolt and an insertion tube for a shunt wire, and the arc-shaped splint and the flat splint are fastened and fixed by the fixing bolt for clamping At the end where the strain clamp drainage plate is connected to the drainage wire; the insertion tube is welded and fixed on the bottom wall of the extended end of the flat splint, the axis of the insertion tube is parallel to the bottom wall of the flat splint, and the end of the shunt wire is inserted into the insertion tube. Secure with flat head screws.

The wire type of the shunt wire is the same as that of the drain wire.

The structure of the diversion plate handle clip is the same as that of the conductor clip, both of which are made of metal.

The beneficial effect of the utility model is that: the heating and diverting device of the tension clamp drainage plate is connected in parallel at both ends of the tension clamp drainage plate through the diversion device, so the transmission line flow through the tension clamp drainage plate is reduced. Current intensity, thereby reducing the heating value of the strain clamp drainage plate. Moreover, since the two ends of the shunt wire are respectively fixedly connected with the conductor clamp and the drain plate handle clamp in advance, it is easy to install on the strain clamp drain plate, the operation is quick and convenient, and the labor intensity of the operators is reduced.
