Problems solved by technology

Arc light grounding overvoltage will saturate the voltage transformer and excite ferromagnetic resonance, resulting in severe overload of the voltage transformer, resulting in blown fuse or burnt transformer
At the same time, due to the long duration of the arc grounding overvoltage, the energy can easily exceed the withstand capacity of the arrester, resulting in the explosion of the arrester
Furthermore, the high-amplitude overvoltage generated by arc grounding aggravates the cumulative damage of solid insulation such as cables and even breakdowns.

Abstract

The invention discloses a special fuse wire protective agent for an arc extinguishing cabinet. The fuse wire protective agent comprises following components in parts by weight: 5-10 parts of flame retardant oil, 1-3 parts of a shrinking agent, 3-5 parts of tin powder, 3-5 parts of magnesium powder, 3-5 parts of sulfur powder, 1-3 parts of sodium hydrosulfide, 3-5 parts of an antioxidant, 3-5 partsof paraffin, 1-3 parts of a curing agent and 1-3 parts of ethylene propylene rubber. When the surface of a fuse wire is coated with the protective agent, the fuse wire is resistant to oxidation and corrosion and can be kept in a very good state, the oxidation resistance and the wear resistance of the fuse wire are improved, the effective components of the protective agent are stable in low-temperature and high-temperature environments, and the sensitivity of the fuse wire is improved.

Description

technical field [0001] The invention relates to the technical field of fusing in an arc-extinguishing cabinet, in particular to a special fuse protection agent for an arc-extinguishing cabinet. Background technique [0002] With the development of the current power grid, it is an inevitable trend that overhead lines are gradually replaced by solid insulated cable lines. Due to the cumulative effect of solid insulation breakdown, its internal overvoltage, especially the arc-ground overvoltage and the ferromagnetic resonance overvoltage generated when single-phase intermittent arc-ground occurs in the power grid, has become the key to the safe operation of this type of power grid. One of the most serious threats is single-phase arc-to-ground overvoltage. Arc light grounding overvoltage will saturate the voltage transformer and excite ferromagnetic resonance, resulting in severe overload of the voltage transformer, resulting in blown fuse or burnt transformer. At the same tim...
