Description
Technical field
The invention belongs to surge arrester failure monitoring device technical fields, and in particular to a kind of lightning-arrest based on Internet of Things Network Communication
Device ground fault detection device.
Background technique
Arrester is the important protection equipment of distribution line, connects between distribution line and the earth, usually sets with by protection
It is standby in parallel.When distribution line and equipment are run under normal working voltage, arrester will not generate effect, to being greatly considered as out
Road；When high voltage occur and jeopardizing distribution line and protected device insulation, arrester starts immediately, presents compared with low resistance
High-voltage impact conduct current the earth to limit voltage magnitude, is protected distribution line and protected device insulation by value；When
After high voltage disappears, arrester restores to the original state rapidly, works normally distribution line and equipment.
If arrester because lightning stroke or self deterioration are broken down, leads to the reduction of its resistance value, under normal circumstances distribution wire
Road generates low current, i.e. arrester ground failure to the earth by arrester, causes to equipment operation and personal safety huge hidden
Suffer from, and the failure is difficult to be found.
