Abstract
The invention is a voltage-equalizing synthetic insulator for high voltage power line, especially suitable for 10-1000 KV power line and including an insulator, where semiconductor material is applied in partial section of core rod and outer protective layer of the insulator near to electrified end and connected with armour clamp of the electrified end, and able to reduce difference in voltage distribution of the whole synthetic insulator and prolong the practical service life of the synthetic insulator.
Description
(1), technical field
The present invention relates to a kind of ultra-high-tension power transmission line synthetic insulator that is used for, be particularly suitable for using on the 10-1000KV transmission line.
(2), background technology
At present, on China's high voltage transmission line, synthetic insulator has obtained using widely.Because its volume is little, in light weight, anti-fouling flashover performance is good, obtains user's favor.But, synthetic insulator is because itself direct-to-ground capacitance is little, therefore, be in operation, the electric-field intensity distribution at each position is extremely inhomogeneous, be example only with the 110KV product, the 3-4 that its highest electric field strength is lowest electric field strength times, along with the raising of electric pressure, this difference that shows can be bigger, long-term outer jacket of working under highfield will quicken galvanic corrosion and decrease with electric aging, causes the shortening in synthetic insulator life-span.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of equalizing synthetic insulator, the difference that it can make whole synthetic insulator voltage distribute reduces, and prolongs the physical life of synthetic insulator.
The present invention solves the technical scheme that its technical problem takes: it comprises an insulator, and the plug of described insulator and outer jacket apply semi-conducting material in the part section of live end, and semi-conducting material is communicated with the gold utensil of live end.
The present invention compared with prior art has the following advantages: the difference that whole synthetic insulator voltage is distributed reduces, thereby reduce the accident that causes because of the voltage uneven distribution, make the degree that the outer jacket galvanic corrosion is decreased and electricity is aging of live end weaken the physical life that prolongs synthetic insulator.Do not change synthetic insulator external form and basic structure, just technology can realize after doing slightly to change, invest little, instant effect.
(4), description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
(5), embodiment
As shown in drawings, the present invention includes an insulator, near live end semiconductor material layer 3 is being arranged between the plug 1 of described insulator and the outer jacket 2, semiconductor material layer 3 is electrically connected with the gold utensil 4 of live end.The thickness of semiconductor material layer 3 is 0.1--4mm, and length is 50--1000mm.Very close to each other between semiconductor material layer 3 and plug 1 and the outer sheath material 2.
Claims (3)
1, a kind of equalizing synthetic insulator, it comprises an insulator, it is characterized in that: the plug of described insulator and outer jacket apply semi-conducting material in the part section of live end, semi-conducting material is communicated with the gold utensil of live end.
2, equalizing synthetic insulator according to claim 1 is characterized in that: very close to each other between described semiconductor material layer (3) and plug (1) and the outer sheath material (2).
3, equalizing synthetic insulator according to claim 1 and 2 is characterized in that: the thickness of described semiconductor material layer (3) is 0.1--4mm, and length is 50--1000mm.
