Description
Technical field
The present invention relates to insulation subdomains, and in particular to a kind of faulty disengaging of band and the lightning-arrest insulation of aging identification function
Son.
Background technology
The landform of 10kV distribution lines process, landforms are various, just like the complicated network structure as spider web, the insulation water of circuit
Flat low, operation and maintenance and the power delivery circuit of circuit have larger gap, and power distribution network is easily subject to damage to crops caused by thunder, causes power failure or tripping
Accident brings serious loss to national economy and people's life.According to statistics, have a power failure caused by damage to crops caused by thunder in distribution line
Accident accounts for the 21.91% of distribution line accident, as China's industrial or agricultural construction flourishes, the increase of transmission ＆ distribution capacitance, to supplying
Electric reliability, simple in circuits beauty etc. propose higher requirement, right in order to ensure the safe and stable operation of electric system
Distribution line take effective Lighting Protection Measures be quite it is necessary to.
Lightning protection insulator is the product for integrating insulator and arrester function, and in operation, lightning protection insulator is usually
Built-in arrester is not subject to working voltage, and after distribution line is by being struck by lightning, arrester can decay the amplitude of lightning current
And steepness, power frequency continued flow is blocked rapidly, effectively limits lightning surge, and reaching prevents aerial condutor from being melted due to power frequency continued flow high temperature
It disconnected (lightning-caused breaking) or trips, circuit and equipment is made to obtain better lightning protection.
Existing compound pillar zinc oxide lightning protection insulator is the most common one kind of lightning protection insulator, by internal clearance group with
Zinc oxide resistance sheet, interior electrode are connected in series with, outer envelope silastic material, and upper end gold utensil is electrode, lower end installation bolt
It is made up of metallic support or wire ground.In long-term use, the main components varistor of zinc oxide lightning protection insulator
It bears operating voltage and bears the effect of different amplitudes, the instantaneous lightning surge, switching overvoltage of pulsewidth, it may occur that electrical resistance
The deterioration of energy increases so as to cause leakage current down to failure and safeguard function fails, possible generating device is exploded, risen when serious
Fire forms permanent lightning fault, and since, without apparent mark, inspection maintenance personnel is not easy to find to have damaged lightning-arrest after damage
Insulator brings hidden danger to the safe operation of distribution line, needs to be improved.
