Temperature-controlled dropout fuse

Abstract

The invention discloses a temperature control drop-out type fuse, belonging to the power supply system technology field. The temperature control drop-out type fuse comprises a drop-out type fuse, a power failure maintenance system and a wind power system; a power failure maintenance system is installed on an installation support of the drop-out type fuse; the wind power system is connected to the power failure maintenance system for supplying power and automatically cooling according to the surface temperature of the drop-out type fuse; the power failure maintenance system starts detecting when the fusing body of the drop-out fuse is in outage for detecting pressure received by the upper contact and the lower contact of the drop-out fuse and detecting the looseness of the fusing body. The temperature control drop-out type fuse is capable of automatic maintenance, monitoring fusing tube temperature and self-function, and fast and convenient. Besides, the temperature control drop-out type fuse can automatically transmit the detection result to the communication tool of the maintenance staff and can solve the problems that the people have to check the drop-out type fuses one by one in a power failure maintenance, which is time-and-labor-consuming and has heavy workload.

Description

technical field [0001] The invention belongs to the technical field of power supply systems and relates to the direction of high-voltage protection appliances, in particular to a temperature-controlled drop-out fuse. Background technique [0002] With the progress of insulation of overhead distribution lines, the power sector has increasingly urgent requirements for the full insulation of dropout fuses used in a large number of lines. The fully insulated high-voltage drop-out current-limiting fuse realizes the overall sealing and insulation of the product, that is, the contact between the product and any external object will not cause conduction or short circuit, thus greatly improving the safety of line operation. [0003] The drop-out fuse is installed on the branch line of the 10kV distribution line, which can reduce the scope of power outage, because it has an obvious disconnection point of the high-voltage drop-out fuse, which has the function of isolating switch, and c...

Problems solved by technology

However, a lot of inspection work needs to be done on the fuse during maintenance: whether the rotating part of the fuse is flexible, whether there are any abnormalities such as rust and rotation failure; Become slack and weak; in this way, the workload of maintenance personnel is relatively large, and it is not easy to locate the problem of finding the drop-out fuse, and the normal use conditions of the product: the ambient temperature is not higher than +40 degrees, not lower than -40 degrees, the ambient temperature of the product It also needs to be controlled, otherwise the product will be burned, exploded and other accidents will delay the normal work of the fuse due to the influence of the environment.
