Example Embodiment

[0012] Such as figure 1 , figure 2 Shown: The heat-preventing device of the isolating switch of the present invention is composed of a shunt short wire 6 and 2 to 4 shunt wire fixing rings 4. The shunt short wire 6 can be copper stranded wire, and its cross-sectional area should meet the maximum load current of the isolating switch Needs. The two ends of the shunt short wire 6 are provided with lead wire clamps 2 for connection with the high voltage lead wire 3. The shunt wire fixing ring 4 is used to fix the shunt short wire 6 to prevent the shunt short wire 6 from swinging under the action of wind. The shunt wire fixing ring 4 adopts a pincer-shaped structure, and has a pair of insulated arc-shaped brackets 7 buckled with each other. One end of the two insulated arc-shaped brackets 7 is hingedly connected, and the other end is in contact with each other. The contact parts of the two insulating arc-shaped brackets 7 are arc-shaped structures, which are convenient to push an...

Abstract

The invention belongs to the technical field of power equipment units, in particular discloses an isolating switch heating-preventing device composed of a shunt short jumper and 2-4 shunt wire fixing rings, wherein the two ends of the shunt short jumper are respectively provided with a lead wire clamp. By adopting the device, overheating of parts of a conducting loop of an isolating switch can be effectively avoided, and the temperature thereof is controlled to be within the range of normal operation, thus reducing frequency of power cut for repairing and improving power supply reliability, and the device has the advantages of low labour intensity, safety and reliability, simple structure as well as economy and practicability, and is rapid in mounting, convenient to use, easy to implement.

Description

technical field [0001] The invention belongs to the technical field of electric equipment components, in particular to an anti-heating device for an isolating switch. Background technique [0002] In the known technology, the abnormal heating of electric equipment has been a problem that has plagued electric workers for many years. Traditional temperature measurement technology is difficult to monitor abnormal low-temperature heating of power equipment, especially the heating of outdoor power equipment is difficult to detect and measure, so it is easy to cause burning of power equipment and even endanger the safe operation of the power system. With the rapid development of science and technology in our country, the popularization and application of high-precision infrared non-contact temperature measurement technology in the power system provides the possibility for us to scientifically and meticulously study the abnormal heating of power equipment. According to the detecti...
