Abstract
The utility model discloses a perforated ring type strain-insulation hanging plate, which comprises a hanging plate body, a plurality of ball-headed hanging loops and a plurality of bowl-headed pressing plates; the ball-headed hanging loops are hung on the hanging plate body through the bowl-headed pressing plates; the perforated ring type strain-insulation hanging plate is characterized in that the hanging plate body is formed through the welding of two annular strain-insulation hanging plates in symmetrical structure; after the two annular strain-insulation hanging plates are combined, a radial section forms a circular section, so as to play the roles of equalized pressing and shielding; and loop tops and loop bottoms of an internal loop surface and an external loop surface of the hanging plate body are provided with water draining holes. The perforated ring type strain-insulation hanging plate does not adopt the fastener connecting, therefore, the installation is convenient and quick, and no hidden danger affecting the line operation exists.
Description
Technical field
The utility model relates to a kind of electric armour clamp, the ring-like tension hanging plate of particularly a kind of porous.
Background technology
At present, the principal voltage grade of China's electric power transmission network is 500kV, and promptly when the electrical network operate as normal, its voltage withstand class is 500kV.Along with economy and science and technology development, the 500kV electric power transmission network can not adapt to the requirement of China's economic construction, and therefore building 1000kV UHV transmission network just becomes the vital task that China's power industry faces.Tension hanging plate is the vitals of transmission line, mainly bears all wire tensions.Lead is connected with tension hanging plate by strain insulator adjustable ring, tension regulator, ball-clevis, guarantees its division radical and spacing by tension hanging plate.The function that existing 500kV-1000kV transmission line self does not have shielding, all presses need add grading ring in addition, causes the tension hanging plate weight of transmission line to increase operation maintenance inconvenience etc.
For this reason, the applicant has invented a kind of " circular ring type self-pressure equalizing tension hanging plate " on August 5th, 2008, and its application number is 200810041400.1, and is now open.This circular ring type self-pressure equalizing tension hanging plate comprises that link plate body, some ball-eyes, some bowl pressing plates, some pressure-bearings close the rubber blanket of vibration damping, and the link plate body is combined by securing member by the strain insulator annulus link plate of two symmetrical structures; After two strain insulator annulus link plate combinations, radial section constitutes a circular cross-section, to play the effect of all pressing and shielding; Circumferentially be evenly equipped with the hole of a plurality of internal diameters greater than a bowl diameter of ball-eye in strain insulator annulus link plate upper edge; Pass and tangle described bowl bulb hanging hole at the bowl head that offers on the bowl pressing plate on the described ball-eye of an appearance, in bowl hole that the bowl head that is offering on the rubber blanket on the described ball-eye of an appearance passes; Hole, the bowl hole on the rubber blanket and the bowl hanging hole on bowl pressing plate that the bowl head of described ball-eye passes on the strain insulator annulus link plate successively hang on the bowl pressing plate.The present invention has well from all pressing effect, need not to increase grading ring again, provides cost savings.But this circular ring type self-pressure equalizing tension hanging plate is owing to the strain insulator annulus link plate of link plate body by two symmetrical structures combines by securing member, install cumbersome, and, causing discharge easily just in case the screw thread of securing member exposes, operation brings hidden danger to circuit.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of porous ring-like tension hanging plate at the existing problem of existing tension hanging plate, the ring-like tension hanging plate of this porous does not adopt securing member to connect, thereby install convenient and swiftly, and there is not any hidden danger that influences circuit operation.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The ring-like tension hanging plate of porous, comprise link plate body, some ball-eyes and some bowl pressing plates, described ball-eye hangs on the described link plate body by a bowl pressing plate, it is characterized in that, described link plate body is welded by the strain insulator annulus link plate of two symmetrical structures; After two strain insulator annulus link plate combinations, radial section constitutes a circular cross-section, to play the effect of all pressing and shielding; The Huan Ding and the ring end at the inside and outside anchor ring of described link plate body are provided with osculum.
On each strain insulator annulus link plate, offer some lightening holes.Be evenly equipped with two holes for hoist on a strain insulator annulus link plate therein.
In preferred embodiment of the utility model, circumferentially be evenly equipped with the hole of four internal diameters greater than a bowl diameter of ball-eye in each strain insulator annulus link plate upper edge, hold the bulb hanging hole that bowl head on the described ball-eye passed and tangled described bowl head offering one on the bowl pressing plate, the bowl head of described ball-eye passes hole on the strain insulator annulus link plate successively and the bowl hanging hole on the bowl pressing plate hangs on the bowl pressing plate.
Owing to adopted technical scheme as above, the utility model not to adopt securing member to connect, thereby install convenient and swiftly, and do not have any hidden danger that influences the circuit operation.
