Abstract
The invention discloses an icing flashover prevention suspension strain insulator string. A power transmission line insulator string connector (1) is provided with a sector connecting plate (12), and a hanging ring (11) is hung at each of two ends of the sector connecting plate. A ball eye (2) is hung at the outer end of each hanging ring (11), an insulator (4) is hung at the outer end of each ball eye (2), a socket clevis (3) is hinged to an upper fan angle of the sector connecting plate (12), and an insulator (4) is hung at the outer end of the socket clevis (3). A suspension straight line string is changed into the suspension-strain string, an insulator umbrella skirt is prevented from being bridged by ice, and anti-icing level is improved. Creep distance is increased, ice coating power frequency flashover voltage is boosted, tower top foul is prevented from forming a rain curtain, bird manure pollution flashover is avoided, lightning flashover voltage is boosted, the size of a tower window and a line corridor are decreased, and investment is saved.
Description
Technical field
The invention belongs to electric power project engineering field, relate to a kind of anti-ice-flashing overhang tension insulator string, use this insulator string can improve the anti-ice-flashing ability of transmission line.
Background technology
Dangle and arrange that insulator string is subject to the impact of creepage distance and dry arcing distance deficiency, in the time that awful weather conditions such as meeting with icing, filth or damage to crops caused by thunder affects, the discharge voltage of these suspension insulators reduces greatly, even there is flashover fault, have a strong impact on the safe operation of electrical network and the people's normal life.Therefore, increase creepage distance and the dry arcing distance of insulator string, to improving covering ice for insulator Power Flashover Voltage, filthy Power Flashover Voltage and lightning impulse discharge voltage, guarantee that the safe operation of transmission line is very necessary.But the old transmission line of most is all the conservative design that adopts economizing type, is subject to the restriction of tower head size and distance to the ground, directly regulate creep distance and dry arcing distance very difficult by increasing insulator sheet number.
Summary of the invention
The technical problem to be solved in the present invention is that the defect existing for known technology, provides a kind of anti-ice-flashing overhang tension insulator string.Use this insulator string can prevent insulator umbrella edge sleet bridge joint, improve icing Power Flashover Voltage, improve filthy Power Flashover Voltage and lightning impulse discharge voltage, thereby the tangent tower to existing tower head size and distance to the ground deficiency is transformed, improve transmission line power supply reliability, reduce investment outlay.
Technical scheme of the present invention is that the anti-ice-flashing overhang tension insulator string providing, referring to accompanying drawing 1, has a transmission circuit insulator string connector 1 that is fan-shaped.This transmission circuit insulator string connector 1 has its arc to be evenly distributed with the fan-shaped yoke plate 12 of round along limit.On the round at these fan-shaped yoke plate 12 two ends, hang respectively a link 11.The outer end of these two links 11 is mounted with respectively a ball-eye 2.The outer end of these two ball-eyes 2 articulates respectively an insulator 4.The fan angle place, round top of described fan-shaped yoke plate 12 is hinged with a socket-clevis eye 3.The outer end of this socket-clevis eye 3 is also mounted with an insulator 4.
When the anti-ice-flashing overhang tension insulator string of the present invention forming thus uses, its insulator 4 connects and composes overhang tension insulator string chain by ball-eye 2, socket-clevis eye 3 and the insulator string connector 1 on power transmission line route.
Operation principle of the present invention is: transmission circuit insulator string connector 1 is connected the drape plot insulator string 4 on transmission line with socket-clevis eye 3 by top link 11, and transmission circuit insulator string connector is connected both sides horizontal linear insulator string 4 along connecting circular hole 1 time with ball-eye 2 by link 11.Regulate the sag of both sides transmission line wire at the link position at fan-shaped yoke plate 12 edges by changing link 11.Utilizing this kind of anti-ice-flashing overhang tension insulator string, is that dangle-tension type is arranged by the drape plot falsification that regulates creepage distance and increase dry arcing distance difficulty.In the situation that not needing change tower head and change distance to the ground, greatly improve creepage distance and the dry arcing distance of insulator string, change its contamination and icing characteristic simultaneously, and then realize the object that improves insulator string external insulation level; In addition, utilize this kind of anti-ice-flashing overhang tension insulator string that drape plot falsification is arranged for dangle-tension type, can effectively prevent that icing insulator umbrella in season is by ice slush bridge joint, improve the anti-ice level of insulator string.
The invention has the beneficial effects as follows:
1), can avoid insulator string on transmission line by sleet bridge joint, increase creepage distance and dry arcing distance, improve icing Power Flashover Voltage, improve filthy Power Flashover Voltage and lightning impulse discharge voltage;
2), can avoid the tower top filthy formation curtain of rain and rain sudden strain of a muscle occurs;
3), can avoid the formation of birds droppings pollution flashover;
4), can improve lightning stroke flashover voltage;
5), can reduce shaft tower window size and circuit corridor, saving investment.
