Embodiment Construction
[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] refer to figure 1 and figure 2 , the preferred embodiment of the present invention provides a kind of strain clamp overtemperature warning device, including the temperature acquisition plate 10 used to collect and transmit the temperature of the heating point of the strain clamp, and the resistance to the temperature acquisition plate 10 transfer. The temperature of the heating point of the tension clip carries out the over-temperature warning plate 20 for over-temperature warning, and the support bracket 30 for connecting the temperature acquisition plate 10 and the over-temperature warning plate 20, and one end of the over-temperature warning plate 20 is connected with the support by...

The invention discloses an over-temperature warning device for a strain-resistant wire clamp, which comprises a temperature acquisition board for collecting and transmitting the temperature of a heating point of a tension-resistant wire clamp, an over-temperature warning board for performing an over-temperature warning on the temperature of a heating point, And the support bracket used to connect the temperature acquisition board and the over-temperature warning board. One end of the over-temperature warning board is movably connected to the support bracket through a spring hinge, and the other end of the over-temperature warning board is closed and connected to the temperature acquisition board through solder joints. There is an over-temperature warning sign on the inner side of the over-temperature warning board. When the temperature of the heating point of the tension clamp transmitted by the temperature acquisition board is greater than or equal to the upper limit temperature of the tension clamp, the solder joint melts, and the over-temperature warning board is placed on the spring. Under the action of the spring force of the hinge, it unfolds to display the over-temperature warning sign. The invention reduces the inspection workload, saves manpower and material resources, reduces the number of live operations, improves the power supply reliability of the power grid, and reduces the risk of power failure caused by the failure of the tension clamp.
Description
technical field [0001] The invention relates to the technical field of high-voltage equipment in a power system, in particular to an over-temperature warning device for a tension clamp. Background technique [0002] Transmission line conductors (including cables) work under the conditions of heavy load, high current and poor contact of connecting fittings for a long time, which can easily cause the temperature of the joint part to be too high and cause various failures. According to incomplete statistics, only 40% of cable faults are caused by poor contact of connectors. Tension clamps are often used to fix the wires in the overhead transmission lines of the power grid system to withstand the tension of the wires, and hang the wires to the tension strings or the metal fittings on the towers to transmit current. In actual operation, such as figure 1 As shown, the bolts 100 at the overlapping joints of the tension clamps are easy to loosen, which will cause the resistance to...
