Description
Technical field
The present invention relates to a kind of preparation processes of 500kV wind-deviation wire jumper insulator used for transmission line.
Background technique
In recent years, the drainage wire jumper in the whole country on multiple area 500kV transmission lines of electricity causes to dodge under the influence of strong wind
Network causes trip accident, and frequency alreadys exceed the acceptable limit of safe operation of power system, is safely operated to power circuit
Bring high risks.According to statistics, windage yaw tripping more than 100 times, model occur altogether for the administrative 500kV of 2018 Nian Guowang companies and Above Transmission Lines
It encloses and is related to the ground such as Jiangsu, Zhejiang, Anhui, Hubei, Henan, Shandong, Shanxi, Beijing, Hebei, northeast.The range of windage yaw electric discharge is wide,
Often, it influences greatly, is occurred especially with the multiple area of coastal area typhoon the most frequent.It is different from lightning stroke flashover and switching impulse flashover
, most windage yaw discharges are occurred under operating voltage, and cannot generally succeed reclosing, are stopped so as to cause route
Fortune, causes heavy losses to national economy.According to the windage yaw trip accident analysis occurred in recent years, the original of wire jumper windage yaw discharge
Because mainly there is the following.
High wind is the most immediate cause of wire jumper windage yaw discharge.Traditional wire jumper insulator string is all made of conventional porcelain, glass, In
Insulator chain is tilted to shaft tower direction in the case where more than design wind speed, reduces the air gap distance of conducting wire and steel tower, when
When not being able to satisfy the minimum voltage requirement of electric discharge flashover just occurs for air gap distance；Route tune climb using after composite insulator not
Windage yaw check is carried out, even if because composite insulator self weight relatively gently will also result in greatly electric discharge plus weight amplitude of fluctuation in windage yaw.
Main solution has at present: 1. reinforce windproof bracing wire, and being fixed on line hardware by bracing wire fixes conducting wire, right
Route, which generates windage yaw, can play good inhibiting effect.But since windage yaw rotates not flexible, prolonged stress, line hardware
Vulnerable to fatigue rupture.Therefore, installing windproof bracing wire additional, there are security risks to route operation；2. installing weight additional, but install weight additional
Effect is limited, is not the major measure for fundamentally solving the problems, such as suspension string windage yaw discharge；3. using wind-deviation insulator: insulation
Sub- wind swing amplitude is small, increases conducting wire-shaft tower electric clearance；Installation is reliable, but for 500kV and Above Transmission Lines by
Larger in insulation outside dimension, conducting wire wind dance is even more serious.
500kV route still uses conventional jumper string due to being limited by composite insulator core bar anti-bending strength.Both at home and abroad
Vertical hanging is generally used for 500kV transmission line of electricity jumper string or carrys additionally the assembling mode of heavy punch piece again, this kind of assembling side
Formula cannot fundamentally solve the problems, such as wire jumper windage yaw discharge；And coastal high wind area is possible to use V-type jumper string assembling mode, by
Need to increase an insulator in it, while wire jumper cross-arm also needs to lengthen, to will cause a larger increase of investment.Due to
500kV line jumpers string length is larger, and wind load is big, and conducting wire is quadripartion form again, exhausted using vertical fixed wind-deviation wire jumper
Edge substring will form biggish moment of flexure in steel tower bearing.
