Abstract
The utility model relates to a tower-connecting tool for an ultra high voltage transmission line strain insulator string. The tower-connecting tool comprises a body. Hangers in rotatable connection with the cross arm of a tower and first bolt groups are formed on the both ends of the body. The middle axis of the body is connected with a haring plate through a second bolt group. A connection board is disposed under the hanging plate and is connected with an insulator chain through a connection hole on the connection board. Two sides, between the connection board and the hanging plate, of the top of the connection board are equipped with reinforcing plates. The body is equipped with spring fixing blocks on the two sides of the hanging plate. Reset springs are arranged between the spring fixing blocks and the hanging plate. The tower-connecting tool is simple in structure and reasonable in design. The tower-connecting tool is equipped with the spring fixing blocks and the reset springs. When the hanging plate is swung, the reset springs may fast reset the hanging plate so as to maintain the stability of the insulator chain and guarantee the stability of a high-voltage tower. The reinforcing plates may improve the connection strength of the hanging plate and the insulator chain and the safety of the hanging plate.
Description
Technical field
The utility model relates to company's tower gold utensil of transmission line, relates in particular to a kind of column-connected hardware fittings for strain insulator string of ultrahigh voltage transmission line.
Background technology
China is building UHV transmission line at present, along with the rising of electric pressure, and the increase of transmission capacity, the radical of sub-conductor increases thereupon, and the cross section of sub-conductor increases.UHV transmission line adopts many division large-section leads, and load certainly will increase by relative supertension line, and strain insulator string mainly bears whole tension force of wire, and therefore the strength grade of strain insulator series winding tower gold utensil is higher.
In China, 1000KV UHV transmission line is considered actual needs, for corner strain tower, the size of strain insulator corner is divided into 0～20 °, 20 °～40 °, 40 °～60 ° three kinds of forms, transmission line changes of hydrogeological condition along the line is very large, need to suit measures to local conditions to select corner strain tower, nonetheless, in transmission line, to receive that the direction of wire tension can not ensure vertical with the direction of cross arm of tower for insulator string, after being installed, connection has corner, hesitate again and be subject to the impact of the weather condition factors such as wind, wire can swing, insulator string and the force direction that is subject to connecting between tower gold utensil also will often change.A kind of column-connected hardware fittings for strain insulator string of ultrahigh voltage transmission line of one that China Patent No. 200820127379.2 is announced at present, although wherein can realize the strain insulator corner of link plate is-45 °～45 °, be subject to extraneous interference but link plate is a kind of, such as strong wind impact etc., will make connected insulator string gold utensil occur significantly to swing, can not realize fast and stable, can have a significant impact the total stability of high-pressure tower like this, and the intensity of joint board being wherein connected with insulator string is inadequate.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of column-connected hardware fittings for strain insulator string of ultrahigh voltage transmission line is provided.
The utility model is to be achieved through the following technical solutions:
A kind of column-connected hardware fittings for strain insulator string of ultrahigh voltage transmission line, comprise body, described body two ends form respectively the hangers being rotatably connected with cross arm of tower, the first bolt group, in the medial axis of described body, be connected with link plate by the second bolt group, the below of described link plate is provided with connecting plate, and connecting plate is connected with insulator string by the connecting hole on it, both sides between upper end and the link plate of described connecting plate are equipped with stiffener, the both sides that described body is positioned at link plate are provided with spring fixed block, between described spring fixed block and link plate, be provided with returning spring.
As preferably, between described stiffener and link plate, be welded to connect.
As preferably, described spring fixed block is greater than the area away from the rectangular surfaces of link plate one side near the area of the rectangular surfaces of link plate one side, and straight transitions between two end faces.
As preferably, between described spring fixed block and body, be welded to connect.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the utility model is by arranging spring fixed block, returning spring, in the time that link plate occurs to swing, returning spring can make link plate Quick-return, keeps the stability of insulator string, thereby ensures the stable of high-pressure tower; By stiffener is set, can improve the intensity that link plate is connected with insulator string, improve its fail safe.
