Description
Technical field
The present invention relates to a kind of pin insulator, be specifically related to a kind of band gap compound needle type insulator, in this insulator
Portion with fixed interval (FI), can with gapless arrestyer with the use of, make gapless arrestyer have the function of arrester with gaps.
Background technology
Transmission line of electricity especially ultra-high-tension power transmission line should be noted that a lot of problem during built on stilts laying, the most normal
See is exactly the problems such as line support, line insulation and overvoltage protection.At present, insulator is used to solve support wire and prevent
Only electric current returns the problem on ground, uses spark gap to exempt from atmospheric over-voltage (usually thunderbolt) with protection transmission line of electricity and electrical equipment
Damage with switching overvoltage.In ultra-high-tension power transmission line, one end of insulator hangs on steel tower, and the other end hangs wire,
Under normal running conditions, insulator can play support wire and the effect of insulation, but be struck by lightning at transmission line of electricity or operate
During overvoltage, insulator all can occur flashover, and i.e. when overvoltage exceedes the design load that insulator can bear, insulator will be by
Electric arc burn is impaired, and then causes transmission line of electricity to trip, and has undesirable effect the productive life of people, even causes bigger
Economic loss.In order to protect insulator so that it is can keep normally working, it is common that use spark gap and insulator on the line
Parallel connection, but, spark gap can only play the effect of lightning protection, can not be used for supporting wire, bears pulling force, and its weight and body
Long-pending relatively big, increase the load of circuit and steel tower while being not easy to install, make line facility complicate.
Traditional gapless arrestyer bears power-frequency voltage the most for a long time, still suffers from overvoltage when being struck by lightning and work
Frequently afterflow, therefore, spark gap is often out of order, and the most aging, and the reliability making distribution line power can not get ensureing.
External series gap spark gap (overvoltage protection device) is widely used the most in practice, and it mainly uses oxidation
Zinc spark gap and external series gap compound mode.Arrester with gaps major part uses extenal fixation gap, when there being overvoltage, big electric current
Puncture gap conducting, big owing to puncturing the dispersibility of gap voltage, during fixed interval (FI) is directly exposed to air in addition, the electricity punctured
Pressure can be affected by environment, causes punch through spread of voltage.Arrester with gaps also has employing internal clearance structure, but mechanism is multiple
Miscellaneous molding difficulty is big, and production cost is higher.
