Description
Technical field
The present invention relates to resistance meter technical field, more particularly to a kind of resistance meter for being easy to workpiece to install.
Background technology
In the last few years, domestic many places transformer station formed expansion accident because of thunderbolt, it is most with ground network ground resistance is unqualified has
Close, grounded screen plays a part of working earthing and protective grounding, when grounding resistance is excessive, occurs to make neutral point during earth fault
Variation increase may make sound phase and neutral point voltage too high, and device damage is caused more than the level of insulating requirements,
When thunderbolt or lightning wave attack, because electric current is very big, very high residual voltage can be produced, makes prestige of the neighbouring equipment by counterattack
The side of body, and the resistance to thunder for reducing grounded screen protection equipment itself (overhead transmission line and Substation Electric Equipment) energized conductor is horizontal,
Do not reach the requirement of design and damage equipment.Whether the grounding resistance of earthed system is qualified simultaneously is directly connected to substation operation
Personnel, substation equipment maintenance and repair personnel's personal safety, but because soil has corrosiveness to earthing or grounding means, with adding for run time
Long, earthing or grounding means can be corroded, and influence the safe operation of transformer station；Therefore, the periodic monitoring to ground network ground resistance is very
Important.
