Abstract
The utility model provides an alternating current gapless metal oxide arrester with a porcelain jacket, which has the advantages that the insulation performance of a core and the electric performance of the product can be improved. The structure of the alternating current gapless metal oxide arrester with the porcelain jacket is as follows: resistance discs of the arrester are connected in series, and the side faces of the arrester resistance discs are winded by alkali-free glass cloth bands dipped with epoxy resin to make the core; after epoxy resin is dried and solidified, the core is placed into the porcelain jacket, the upper end of the core is connected with a porcelain jacket high-voltage flange through a spring, a pressure plate and the like, and the lower end of the core is led out through a low-voltage binding post. A sealing ring is adopted for sealing at the joint of the pressure plate, the low-voltage binding post and the porcelain jacket flange. Insulating gas is filled inside a product. By adopting the arrester, the insulation performance of the core and the electric performance of the product are improved, the structure of the arrester is simplified, and the reliability of safe operation of the arrester is improved.
Description
(1) technical field
The porcelain overcoat that the utility model relates to a kind of novel insulation system exchanges gapless metal-oxide lighting arrester, relates to electric power system and uses the overvoltage protection device field.
(2) background technology
The prevailing overvoltage protection device of China is a metal oxide arrester at present.The lightning arrester of forming by the zinc oxide nonlinear resistance slice serial or parallel connection.Metal oxide resistance is the lightning arrester core parts.
It is present, the most frequently used overvoltage protection device of transformer station that the porcelain overcoat exchanges gapless metal-oxide lighting arrester.The quality of its performance directly has influence on whole electric power system.
The traditional porcelain overcoat exchanges the gapless metal-oxide lighting arrester structure, be the core body of packing in insulator, core body mainly is made up of resistor disc, insulating bar, fixed head etc., adopts insulating bar to grip around the resistor disc, support with fixed head between resistor disc post and insulating bar, charge into insulating gas in the insulator.
The porcelain overcoat of traditional structure exchanges gapless metal-oxide lighting arrester, has certain dielectric strength, can long-time running.But this core group structure the time is difficult to guarantee that enough gaps are arranged between resistor disc and insulating bar in assembling, is jolted in transit in addition, is easy to cause between resistor disc and insulating bar the gap too small, corona discharge occurs after causing adding voltage.And complex structure, annex is more, and is easier in its annex especially insulating bar quality problems causes the lightning arrester accident.
(3) summary of the invention
For improving core body insulation property and the product electric property that the porcelain overcoat exchanges gapless metal-oxide lighting arrester, the purpose of this utility model provides a kind of innovative design porcelain overcoat and exchanges gapless metal-oxide lighting arrester.This lightning arrester can not only improve the product electric property, simplifies the type lightning arrester structure simultaneously, improves the reliability of its safe operation.
The technical scheme core that its technical problem that solves the utility model adopts is: adopt the series connection of clamping servicing unit fixing the lightning arrester resistor disc, twine the alkali-free glass strap of epoxy resin dipping in resistor disc post side, put it in the drying box dry solidification and make core body.Core body is packed in the insulator, and the upper end is connected with the high-voltage connection plate by the conducting rod jockey, and draw by low-voltage wiring terminal the lower end.The sealing ring sealing is adopted in conducting rod jockey, low-voltage wiring terminal and insulator junction.Insulating gas is filled in product inside.The use of the alkali-free glass strap of epoxy resin dipping has improved core body insulation property and product electric property.
This design beneficial effect is:
1) simplified structure is easy to the product assembling.
2) simplify assembling process of products, improved the qualification rate of product.
3) reduce parts, reduced the probability that parts such as defective insulating bar cause the accident.
4) improved the electric property of lightning arrester product.

The lightning arrester resistor disc adopted add that to hold the servicing unit series connection fixing, twine the alkali-free glass strap (5) of epoxy resin dipping in resistor disc post (4) side, put it in the drying box dry solidification and make core body (4), (5).Core body is packed in the insulator (6), and the upper end is connected with terminal block (1) by conducting rod jockey (3), and draw by low-voltage wiring terminal (9) lower end.Conducting rod jockey (3), low-voltage wiring terminal (9) and insulator (6) junction adopt sealing ring (2) sealing.Insulating gas (7) is filled in product inside.
The effect of each parts is as follows among Fig. 1:
One, terminal block (1), the drawing with housing of high and low pressure current potential of the inner core body of lightning arrester insulated.
Two, sealing ring (2), the sealing of assurance product.
Three, conducting rod jockey (3) guarantees that the hot end of resistor disc reliably is connected with terminal block.
Four, resistor disc post (4), the core parts of lightning arrester, overvoltage protection effect.
Five, alkali-free glass strap (5), fixed resistance sheet post strengthens resistor disc post external insulation.
Six, insulator (6) strengthens the anti-environment filth of external insulation and lightning arrester.
Seven, insulating gas (7) is strengthened the insulation of lightning arrester high-low pressure current potential.
Eight, the hydrone in the middle of the adsorbent (8), absorbent insulation gas.
Nine, low-voltage wiring terminal (9), the lead-in wire ground connection of lightning arrester.
This utility model designs simplification is easy to the product assembling, has improved the qualification rate of product, has reduced parts, has reduced rate of failure, has improved the electric property of lightning arrester product.
