Description
Technical field
It the utility model is related to a kind of high-tension overhead line arrester, more particularly to it is a kind of applied to 10kV ratings above
The integrated self arc Multiple level arrester of high-tension overhead line.
Background technology
Domestic and international high-tension overhead line causes huge economy because the accidents such as lightning stroke trip and insulator arc-over occur again and again
Loss, the safe operation of serious threat electric line.
The effective lightning protection measures of high-tension overhead line are wiring arresters, and the circuit used at present on overhead transmission line is kept away
Thunder device mainly has zinc oxide lightning arrester for power lines and portable protective gaps arrester etc..Zinc oxide lightning arrester for power lines technology maturation, can
Extinguish power frequency continued flow, largely used in overhead transmission line；But its discharge capacity is small, it is a large amount of to be produced in operation because of performance degradation
Operation and maintenance cost.Portable protective gaps arrester discharge capacity is big, simple and practical；But power frequency continued flow when being struck by lightning be present and cause line
Road tripping operation, the disadvantage for reducing dielectric level of the circuit under Lightning Over-voltage.
The content of the invention
The purpose of this utility model, which is that, overcomes shortcoming and defect existing for existing line arrester technology, there is provided a kind of
Integrated self arc Multiple level arrester applied to the high-tension overhead line of 10kV ratings above.
What the purpose of this utility model was realized in：
Specifically, the utility model includes upper connection gold utensil, lower connection gold utensil, plug, the snakelike umbrella disk of silicon rubber, electricity
Pole, upper long gap electrode, lower long gap electrode and insulator umbrella disk；
Its position and annexation are：
Connection gold utensil and lower connection gold utensil are connected in the upper and lower side of plug, is covered respectively in the top and the bottom of plug
There are the snakelike umbrella disk of silicon rubber and insulator umbrella disk, multiple electrodes are evenly arranged with the snakelike umbrella disk of silicon rubber；
Upper long gap electrode is arranged between the snakelike umbrella disk of silicon rubber and insulator umbrella disk and is connected with electrode；
Lower long gap electrode is arranged between insulator umbrella disk and lower connection gold utensil and is connected with lower connection gold utensil.
Working mechanism of the present utility model：
When high-tension overhead line is by being struck by lightning, the Multiple level and long gap in this arrester are breakdown, and lightning current passes through
Multiple level and long gap are released, while power-frequency voltage can produce power frequency continued flow along this arc channel；Electric arc is between more
Between gap burning caused by high temperature can make gap gas drastically expand with air pressure increase, electric arc is under the driving of air pressure towards opening
Direction sprays and is elongated, the increase of arc road resistance, the drop increase of Multiple level arc voltage；Multiple level arc voltage drops and long gap arc voltage drop is common
Effect causes electric current persistently to reduce until power-frequency voltage does not maintain arc burning, arc extinction.
The utility model has following advantages and good effect：
1. the integral application of Multiple level and long gap, discharge capacity is big, and self arc performance is good；
2. long gap undertakes most of voltage during normal operation, extinguish electricity jointly with long gap using Multiple level during thunderbolt
Arc, reliability increase；
3. long gap size is fixed, discharge stability is reliable；
It is 4. longer using the insulation self-healing of air, its service life；
5. it is easy for installation, suitable for the lightning protection of 10~220kV voltage class overhead transmission lines.
