Insulator arc-over gap.
Background technology
Discharging gap, also known as portable protective gaps, it is generally by aerial two metal bars for being separated by certain interval of exposure
Composition a, wherein metal bar and the power supply phase line L1 or zero curve of required protection equipment（N）It is connected, another metal bar and ground connection
Line（PE）It is connected, when instantaneous overvoltage attacks, lasting power frequency arc passes through parallel connection under electric power and thermal stress effect
The discharge channel that gap is formed, leads to parallel connection gaps electrode tip, and arc root is fixed on parallel connection gaps electrode tip, so as to protect
Insulator is from electric arc calcination.
Portable protective gaps simple structure, easy to maintain, the structure of normal gap has three kinds of rod type, ball-type and angle-style.Between rod type
The volt-second characteristic of gap is steeper, is not easy to coordinate with the insulation characterisitic of equipment；Although ball-type gap volt-second characteristic is most flat, protective value
Also very well, but it is as rod-gap, the shortcomings that all easily burn there is gap termination, the increase of burnt degree clearance distance, no
It can guarantee that accuracy of action；During angle-style gap discharge, electric arc can be rapidly moving upward along goat's horn and be elongated, thus easily from
Row arc extinguishing, gap will not serious burn, so, angle-style gap is widely used in the lightning protection of distribution line and controller switching equipment in recent years
In protection.
Under normal circumstances, portable protective gaps are insulation over the ground, and dielectric strength is less than the insulation water of institute's protection circuit
