Abstract
The utility model relates to a corona free tension regulator, comprising a connecting screw rod. The middle of the rod part of the connecting screw rod is provided with a bare rod, and the two ends are provided with a screw rod. The screw rod is provided with external screw threads and two adjusting screw sleeves. One end of the screw sleeve is internally provided with a screw hole. The screw hole is provided with internal screw threads. The other end of the screw sleeve is provided with a circular buckle. The screw rod part of the connecting screw rod is screwed into the connecting screw rod through the screw hole positioned on one end of the adjusting screw sleeve. The two connecting ends of the circuit are hanged on the circular buckles of the two adjusting screw sleeves. The screw thread length of the connecting screw rod is shorter than that of the screw hole. With the above technical proposal, the distance and the extension between an insulator string and the rod tower, and the insulator string and the circuit can be adjusted without distance by rotating the connecting screw rod. The exposed parts of the utility model all adopt a round arc shape, thereby avoiding corona phenomenon. Besides, no other anti-corona devices need to be assembled, thereby decreasing the cost of the circuit.

Technical field
The utility model relates to the connection gold utensil of ultra-high-tension power transmission line, particularly a kind ofly can effectively regulate between insulator string and shaft tower and the corona free tension regulator of length and tension force between insulator string and the lead.
Background technology
At present in China 500kV, 110kV and the 220kV circuit, when mounted, need to regulate the syndeton length between them and the tension force of circuit between insulator string and shaft tower and between insulator string and the circuit.And all be to adopt adjustable plate as depicted in figs. 1 and 2 to regulate basically in these circuits at present.Adjustable plate as shown in Figure 1 is a rectangular plate 1, has the adjustment hole 11 that spacing does not wait on the plate, is scalable in the adjustment hole 11 that two union end bolts on the circuit are different.Adjustable plate as shown in Figure 2, be side's plate 1 ', offer at an angle of plate a hole 11 ', and the opposite side of plate offer with the adjustment hole 12 of this hole ＇ center line different distance ', with a union end bolt on the circuit this hole 11 ' in do not have, other end bolt different adjustment hole 12 ' in can regulate.
Because the design feature of above-mentioned adjustable plate makes adjustable range to carry out at interval, can not realize the adjustment of distance continuously, causes each bar circuit tension force unbalanced.Above-mentioned in addition adjustable plate is easy to generate corona, therefore also needs to install additional corona-proofing device, makes line cost increase.Can not belt tension regulate dangling of lead when it is regulated simultaneously, use inconvenience.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of corona free tension regulator, can not have the compartment of terrain and regulates between insulator string and shaft tower and spacing and tension force between insulator string and the circuit.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of corona free tension regulator is characterized in that it comprises:
One connects screw rod, is one section polished rod in the middle of the bar portion of described connection screw rod, and two ends are screw rod, and described screw rod is provided with external screw thread;
Two Adjusting bolt Adjusting screws, the inside of described swivel nut one end is provided with screw, and described screw is provided with internal thread, and the other end of described swivel nut is provided with latch closure;
The screw portion of described connection screw rod screws in wherein from the screw of Adjusting bolt Adjusting screw one end, and two union end bolts of described circuit are hung on the latch closure of described two Adjusting bolt Adjusting screws.
The external screw thread of described connection screw rod is a right-handed thread, a left hand thread; One of internal thread in the described screw is a right-handed thread, and one is left hand thread.
The outer periphery at place is equipped with annular enclosed grading ring in the middle of the bar portion of described connection screw rod, and described grading ring is connected the middle place of bar portion of described connection screw rod by pillar.
The polished rod position of described connection screw rod is a round bar, and the cross section of latch closure is oval.
In order to prevent to connect screw flight in adjustment process, expose outside the Adjusting bolt Adjusting screw, described connection screw flight is shorter in length than the length of described screw.
After the utility model adopts technique scheme, can be continuously adjust in the circuit between insulator string and shaft tower and spacing and tension force between insulator string and the circuit apart from ground by the rotation Adjusting bolt Adjusting screw.Exposed parts of the present utility model all adopts circular arc, thereby can prevent the generation of corona phenomenon, need not corona-proofing device be installed in addition again, has reduced the cost of circuit.The utility model can belt tension be regulated the degree of speeding of lead, and is very easy to use.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of corona free tension regulator, it comprises connection screw rod 3 and two Adjusting bolt Adjusting screws 4.
Shown in Fig. 3,4, be one section polished rod 32 in the middle of the bar portion of the bar portion of connection screw rod 3, two ends are screw rod 31, and polished rod 32 positions are round bar, and the cross section of latch closure 33 is circular.31 1 of screw rods that connect screw rod 3 are right-handed thread, one is left hand thread, for the discharge of shielding insulation, the outer periphery at place is equipped with annular enclosed grading ring 34 in the middle of the bar portion that connects screw rod 3, and grading ring 34 is connected place in the middle of the bar portion that connects screw rod 3 by three pillars 33.
As shown in Figure 5, an end of two Adjusting bolt Adjusting screws 4 offers screw 41, and 41 1 of screws are right-handed thread, and one is left hand thread.Termination at the other end of Adjusting bolt Adjusting screw 4 is provided with latch closure 42.
During use, screw rod 31 parts that will connect screw rod 3 earlier screw in wherein from the screw 41 of two Adjusting bolt Adjusting screws 4, two union end bolts with circuit are hung on the latch closure 42 of two Adjusting bolt Adjusting screws 4 then, make and connect screw rod 3 relative motions, with the distance between two union ends that shorten circuit, and then the tension force of adjusting circuit; Grading ring 34 can also play the effect of wrench, is convenient to regulate the tension force of circuit.
