Description
Technical field
The present invention relates to lightning arrester, particularly to a kind of intelligent lightning protection system being arranged on power circuit,
Surge arrester failure, and auto-alarming can be monitored in real time.
Background technology
Atmosphere produces negative thundercloud during flowing, along with the accumulation of negative electrical charge in negative thundercloud, its electric field
Intensity is gradually increased, and when reaching to a certain degree, i.e. starts the electric discharge of ladder-type jump downwards, the most descending
Pilot discharge.When this descending leader moves closer to ground object and reaches certain distance, ground object exists
Produce point discharge under highfield effect, and form upward leader, and develop towards descending leader direction, two
Person i.e. defines lightning channel after joining, and is the formation of thunder and lightning therewith.It is generally believed that when thunder and lightning descending leader
When thundercloud develops downwards, its ladder-type jumps only to be affected by ambient atmosphere, the mesh that neither one determines
Mark.Only when completing last ladder-type and jumping, it just must select one and be hit object.Therefore, may be used
To install arrester on protected object, upward leader and descending leader is made to join, to avoid thunderbolt.

The metal wire dodged is referred to as lightning conducter, connects the metal tape of sudden strain of a muscle, wire netting is referred to as lighting proof strip, lightning conduction.Lightning rod
Exceed protected object, again with the earth be joined directly together, when lightning leader close to time, electric-field strength between it and thundercloud
Degree maximum, thus the passage of thundercloud discharge can be attracted to lightning rod itself, and through downlead and earthing or grounding means
Lightning current is released to safely in the earth, makes protected object body from direct stroke.
Owing to outdoor transmission line of electricity generally sets up in high-altitude, easily become thunder and lightning is hit object, thus at frame
Generally equipped with overlapping lightning arrester on empty transmission line of electricity more.But, after lightning arrester damages, can lose and keep away
Thunder effect, as do not found the lightning arrester of fault in time, easily makes circuit be struck by lightning, causes large area
Have a power failure.
