Fault indicator

Abstract

The invention discloses a fault indicator. The fault indicator comprises an upper machine casing, a lower machine casing, a plastic thin sheet, an electric control thermal explosion pipe device, a spring device and a vibration absorption device, wherein the plastic thin sheet is embedded into the lower left end of the lower machine casing; the electric control thermal explosion pipe device and thespring device are mounted in the lower machine casing; the vibration absorption device is mounted in the upper machine casing; when a circuit system has faults and the electric control thermal explosion pipe device is exploded, a colored ribbon and the spring device are pushed to move upward; meanwhile, the plastic thin sheet is extruded and the spring device regains the elasticity to push out the colored ribbon downward, so that the working of the fault indicator is realized, the working intensity of detectors is reduced and the manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of power grid line detection equipment, in particular to a fault indicator. Background technique [0002] In the power grid system, the circuit situation is complicated, and there are branches of various lines. Once the circuit in a certain place fails, engineers need a lot of time to check the circuit, especially in remote mountainous areas, where the geographical form is complex and the inspection work is very difficult. With the With the advancement of science and technology, indicators have been widely used as a technical means of fault location. [0003] When the traditional fault indicator is put into use, it is detected by the indicator light of the fault indicator. Since the indicator light is not large in size and is also affected by location factors, it is also easily disturbed by rain and snow. It is difficult to observe whether the indicator light is When it is turned on, inspectors need to go t...

[0003] When the traditional fault indicator is put into use, it is detected by the indicator light of the fault indicator. Since the indicator light is not large in size and is also affected by location factors, it is also easily disturbed by rain and snow. It is difficult to observe whether the indicator light is When it is turned on, inspectors need to go to the scene to check the indication of the indicator, which wastes a lot of manpower and material resources and brings great difficulties to the inspection work.
