Background technology
In electric power system, power transmission and transformation and controller switching equipment are in operation and can be subject to the effect of following several voltage: the operating voltage of (1) long term; (2) due to the temporary overvoltage of earth fault, resonance and other reasons generation; (3) lightning overvoltage; (4) switching overvoltage.Wherein, lightning surge can sense larger temporary overvoltage in signal line and loop thereof; higher magnitude of voltage may be had; easily circuit is damaged; simple dependence improves apparatus insulated level and bears lightning surge; not only unreasonable economically; and be also often impossible technically; therefore; necessary thunder And Lightning Preventive Measures must be taked to electric equipment various in electric power system; when there being lightning impulse, lightning voltage amplitude being limited in protected equipment lightning impulse below horizontal, making electric equipment protected.
In apparatus for preventing thunderbolt, lightning-protection module be after the high pressure by sensing on circuit moment circuit and " " connection releases lightning current, make the form of module, as required, lightning-protection module is generally made up of several module, potential difference is there is when sensing high pressure between the conducting metal position of module, when voltage's distribiuting is uneven, easily the phenomenon of climbing along appearance as water wave sample electric arc is produced between conducting metal position and insulation module material surface, i.e. creepage phenomenon, now, there are slight electric discharge phenomena on insulating material surface, cause the channels and collaterals shape spark tracking of insulating material surface in dendroid or in leaf, wherein, creepage distance is called along the distance of insulating material surface discharge and leakage distance, be called for short creep distance, in existing lightning-protection module, creepage distance between conducting metal position is short, under high-tension impact, be easy to creepage phenomenon occurs, and lightning-protection module is in the process used, be subject to the impact of air humidity, more easily there is creepage phenomenon, once generation creepage phenomenon, if the leakage current path formed on insulating material surface forms a conductive path, then there will be dielectric surface flashover or punch-through, can have an accident time serious, potential safety hazard is serious.
In addition, electric clearance between conducting metal position generally can bear very high overvoltage, but after overvoltage value exceedes a certain critical value, this voltage can cause electrical breakdown soon, and in existing lightning-protection module, electric clearance is unreasonable, under high-tension impact, be easy to breakdown, electric insulating quality is poor.
Utility model content
