Description
Technical field
The present invention relates to the subdomains that insulate, and in particular to a kind of lightning-arrest insulation with faulty disengaging and 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 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, cause power failure or trip
Accident, serious loss is brought to national economy and people's life.According to statistics, the power failure in distribution line caused by damage to crops caused by thunder
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 be attractive in appearance etc., and aspect proposes requirement higher, right in order to ensure the safe and stable operation of power system
Distribution line takes effective Lighting Protection Measures to be quite necessary.
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 struck by lightning, arrester can decay the amplitude of lightning current
And steepness, power frequency continued flow is blocked rapidly, lightning surge is effectively limited, reaching prevents aerial condutor from being melted because of power frequency continued flow high temperature
Disconnected (lightning-caused breaking) or tripping operation, makes circuit and equipment obtain more preferable lightning protection.
Existing compound pillar zinc oxide lightning protection insulator is the most frequently used one kind of lightning protection insulator, its by internal clearance group with
Zinc oxide resistance sheet, interior electrode are connected in series, 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 piezo-resistance of zinc oxide lightning protection insulator
Bear operating voltage and bear different amplitudes, the instantaneous lightning surge of pulsewidth, the effect of switching overvoltage, it may occur that electrical resistance
Down to failure, so as to cause leakage current increase and safeguard function to be failed, possible generating device explodes, rises when serious for the deterioration of energy
Fire, the permanent lightning fault of formation, and because, without substantially mark, inspection attendant is difficult to find that has damaged takes shelter from the thunder after damage
Insulator, brings hidden danger, it is necessary to be improved to the safe operation of distribution line.
The content of the invention
It is an object of the invention to provide a kind of lightning protection insulator with faulty disengaging and aging identification function, to improve event
