Abstract
The utility model relates to a closed anti-falling serial insulator linking bowl head with an inner wedge, which is used in a power transmission line and comprises a frame of the closed bowl head, two ball sockets of the inner wedge and a bolt. The frame of the closed bowl head and the ball sockets of the inner wedge are symmetrically provided with a bolt hole; the frame is shaped like an inversed Chinese character meaning ''concave''; the upper part of the frame is provided with a hole; the inside of the frame is hollow; the ball sockets of the inner wedge is arranged in the frame of the closed bowl head; a bolt (3) is tightened with a linking plate through the bolt hole of the frame (1) of the closed bowl head and the ball sockets (2) of the inner wedge. The installation has the following steps: the frame of the closed bowl head is sleeved on the ball head of the insulator and closely lean against the side of the insulator; the two ball sockets of the inner wedge are arranged in the frame of the closed bowl head and is embed on the ball head of the insulator; finally, the closed anti-falling serial insulator linking bowl head with an inner wedge is connected with the corresponding linking plate; the bolt is arranged for tightening. The linking bowl head has a completely closed structure, which is not only practical and effective, but also can be easily produced and can facilitate the installation and construction.
Description
Technical field
The insulator bowl head that the utility model relates to a kind of used for transmission line connects gold utensil, is to prevent that the overhead transmission line insulator from falling to go here and there the gold utensil class device of fault, a particularly a kind of special bowl gold utensil that replaces the conventional bowl head of existing used for transmission line.
Technical background
Ultra-high-tension power transmission line comprises that superhigh pressure and UHV transmission line insulator string mainly adopt bulb ball-and-socket connected mode at present, used connection bowl head, mostly be open type greatly, for satisfied installation assembling cooperation and under various service conditionss, guarantee the needs of rotation flexibly, bulb is connected with certain clearance with the bowl head, after the two connects, by R or the locking of W locking pin, but under the complex state that does not stress after the insulator string windage yaw, insulator pin is deviate from from the bowl head easily, falls the string accident, especially along with electric pressure rising insulator string length increases, influence the safe operation of transmission line and electrical network.
Summary of the invention
The purpose of this utility model is fallen string in order to prevent electric transmission line isolator, a wedge sealed insulating connection bowl head in a kind of used for transmission line is provided, the utility model comprises that at ultra-high-tension power transmission line superhigh pressure and extra high voltage line are because of the high characteristics of the easy release failure rate of insulator string, utilize unique interior wedge enclosed construction design, be intended to fundamentally reduce ultra-high-tension power transmission line and comprise that superhigh pressure and extra high voltage line insulator fall the string accident, improve the purpose of electric power netting safe running level.The utility model is made production easily, also is convenient to installation.The utility model be applicable to 110kV～500kV until 1000kV and ± 800kV transmission line wire insulator string on, bulb and the bowl connected mode use.
The technical solution of the utility model is:
The closed anti-lost insulator string of wedge connects the bowl head in the used for transmission line, comprise a sealing bowl housing 1, two interior wedge ball-and-sockets 2, bolt 3, all have bolt hole symmetrically on a sealing bowl housing 1, the interior wedge ball-and-socket 2, the shape such as mirror writing " recessed " word of a sealing bowl housing 1, and have the hole on the top that will seal a bowl housing 1, and the inside that will seal a bowl housing 1 hollows out, interior wedge ball-and-socket 2 is placed on 1 li of a sealing bowl housing, and bolt 3 is fastening by the bolt hole and the yoke plate of a sealing bowl housing 1, interior wedge ball-and-socket 2.The method that the closed anti-lost insulator string of wedge in the used for transmission line connects the bowl head is installed is: will seal a bowl housing 1 earlier and be enclosed within on the insulator pin and near the insulator side, two interior wedge ball-and-sockets 2 are put in the sealing bowl housing 1, and be mounted on the insulator pin, at last with the closed anti-lost tandem junction bowl head of interior wedge again with after corresponding yoke plate links to each other, it is fastening to put on bolt 3.Two interior wedge ball-and-sockets 2 are made split or integral body.
The closed anti-lost insulator string of wedge connects a bowl head in the related electric transmission line isolator of the utility model, comprises the bulb ball-and-socket connected mode of the 160kN, the 210/240kN that meet international electrical engineering standard (IEC) 120 and standard GB/T4056-1997 " high-tension line suspension insulator syndeton and size ", 300kN, 400kN, 530/550kN equal strength series.Manufacture is forging and hot investment casting etc.
The related product of the utility model also can be gone here and there use on transformer station, current conversion station equipment frame insulator.
Also there is not the insulator of the used for transmission line of the similar version of the utility model to connect the bowl head with domestic in the world at present.This product is a complete closed formula structure, and both practicability and effectiveness was made easily again and produced, and also was convenient to installation.

Embodiment
In conjunction with the accompanying drawings the utility model is further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises a sealing bowl housing 1, two interior wedge ball-and-sockets 2, bolt 3, all have bolt hole symmetrically on a sealing bowl housing 1, the interior wedge ball-and-socket 2, the shape such as mirror writing " recessed " word of a sealing bowl housing 1, and have the hole on the top that will seal a bowl housing 1, and the inside that will seal a bowl housing 1 hollows out, interior wedge ball-and-socket 2 is placed on 1 li of a sealing bowl housing, and bolt 3 is fastening by the bolt hole and the yoke plate of a sealing bowl housing 1, interior wedge ball-and-socket 2.The method that the closed anti-lost insulator string of wedge in the used for transmission line connects the bowl head is installed is: will seal a bowl housing 1 earlier and be enclosed within on the insulator pin and near the insulator side, two interior wedge ball-and-sockets 2 are put in the sealing bowl housing 1, and be mounted on the insulator pin, at last with the closed anti-lost tandem junction bowl head of interior wedge again with after corresponding yoke plate links to each other, it is fastening to put on bolt 3.
No matter what the shape and size shape of a bowl housing, interior wedge done and changed, as long as wedge is closed promptly in protection range of the present utility model in taking.
The two ends of conventional composite insulator, long excellent porcelain insulator are all manufactured bulb, utilize the utility model to realize connecting, thoroughly eliminate composite insulator, long excellent porcelain insulator since bulb and bowl be connected come off cause the string accident.
V insulator string string for compact, superhigh pressure, ultra high voltage, the two ends of composite insulator, long excellent porcelain insulator are all manufactured bulb, utilize the utility model realize to connect, thoroughly eliminate composite insulator, long excellent porcelain insulator since bulb and bowl be connected come off cause the string accident.
The closed anti-lost insulator string of interior wedge connects the bowl head does not have the copper of conventional bowl head or the R or the W locking pin of steel, saves the consumption of non-ferrous metal.
The related product of the utility model also can be gone here and there use on transformer station, current conversion station equipment frame insulator.
