Description

Two division conductor spacers

Technical field

The utility model relates to a kind of two division conductor spacer, refers to a kind of insulation gap rod that is used in double bundle conductor in the high voltage circuit of specializing in especially.

Background technology

Known high-tension electricity power transmission sequence; no matter be conductors on quad bundled or double bundle conductor; because of the lead of overhead transmission line between electric tower and the electric tower is subjected to the wind-force function influence; vibrate through regular meeting; under special meteorological condition and topography and geomorphology, lead also can take place very rare upper and lowerly significantly to beat " the waving phenomenon " that promptly is commonly called as; conductor galloping causes the lead swinging cross easily, causes air insulation to puncture, and more can cause the damage of line insulator, gold utensil, cross-arm or shaft tower parts when serious.Therefore, between bundle conductor, all must use the insulation gap rod that lead is separated, could suppress to take place between the lead to wave mutually.

The formation of known two division conductor spacers comprises a columned insulation mandrel and the tapered end that is connected at the plug two ends, and the two ends tapered end is symmetrical equidirectional setting, and is because known insulation mandrel is a cylindrical shape, so wind area is bigger, stressed also stronger; On the other hand, be and be symmetrical arranged,, cause the beat twist easilier so when meeting the high wind invasion and attack, the situation of unbalance can take place the two ends tapered end because of the two ends tapered end is positioned at same direction.

Summary of the invention

Main purpose of the present utility model is to provide a kind of two division conductor spacer, the insulation mandrel of order connection two ends tapered end is the plate body of a curved shape or biconvex arc shape, its structural strength is splendid, and can reduce its wind area, so can reduce the stressed degree of insulation gap rod, improve the conductor galloping phenomenon.

Secondary objective of the present utility model, be to provide a kind of two division conductor spacer, further make the tapered end that is connected at twisted plate sheet or biconvex arcuation insulation mandrel two ends, be provided with for being respectively relatively oppositely, improve the situation of two ends tapered end generation unbalance by this, two division conductor spacers are installed on the double bundle conductor, can suppress its beat twist in order to keep the balance and stability between the lead.

Another purpose of the present utility model, be to provide a kind of two division conductor spacer, the described tapered end of being located at twisted plate sheet or biconvex arcuation insulation mandrel two ends, all articulated and formed by two and half locking plates, its inboard half locking plate and insulation mandrel can be that one links to each other or suitably combination, and the outside half locking plate then is provided with one or morely anti-ly waves hook, makes hook can supply eccentric hammer (weight) to be suspended, to suppress the amplitude of conductor galloping, obtain the better anti-effect of waving by this.

The purpose of this utility model is achieved in that a kind of two division conductor spacer, for specializing between the bundle conductor that is set up in high voltage circuit, two leads are insulated separated, comprise that two tapered ends that have the insulation mandrel of designated length and be divided into two ends connect to form, described insulation mandrel is for connecting the two ends tapered end, each is organized tapered end and is all articulated by two and half locking plates and forms, and central authorities' formation one lead locking holes; It is characterized in that: insulation mandrel is for being a plate body, and inboard half locking plate of two ends tapered end forms one with insulation mandrel and links to each other.

Described two division conductor spacer, insulation mandrel is the plate body of rule or irregular curved shape.

Described two division conductor spacer, insulation mandrel is the insulation board lamellar body of biconvex arc shape.

Described two division conductor spacer, insulation mandrel is inboard half locking plate that vertical direction is connected in the two ends tapered end.

Described two division conductor spacer, the locking plate that is connected at twisted plate sheet insulation mandrel is provided with the one or more anti-hook of waving.

Embodiment

As shown in Figure 1, two division conductor spacer of the present utility model, two tapered ends 2 that comprise an insulation mandrel 1 and be divided into its two ends connect to form, specialize between the bundle conductor 3 that is set up in high voltage circuit, two leads 3 are separated, wherein: insulation mandrel 1 is for connecting two ends tapered end 2, for being just like the S shape or the suitable plate body of curved shape, and has designated length; Two ends tapered end 2 (as Fig. 2 or shown in Figure 3), each is organized tapered end 2 and all is made up of 21,22 pivot joints of two and half locking plates, central authorities also form a lead locking holes 23, are located at 21 of half inboard locking plates and insulation mandrel 1 and are one link to each other (or being the suitable combination of other equivalence); The formation of the above-mentioned two division conductor spacers of mat, can utilize two ends tapered end 2 respectively for two leads 3 ccontaining again with bolt 4 with tapered end 2 lockings (as Fig. 4 or shown in Figure 5), conductor spacer can firmly be set up between two leads 3, because of insulation mandrel 1 is the plate body of a S shape curved shape, so structural strength is splendid, and wind area is less, therefore can reduce the stressed of insulation gap rod, improves the phenomenon that lead 3 is waved.

Above-mentioned insulation mandrel 1 shown in Fig. 6 or each embodiment of Fig. 7, can be the rule or the plate body of irregular S shape curved shape, or can be vertical direction, also can be the accumbency direction in case of necessity and is connected in inboard half locking plate, 21 (not shown) of two ends tapered end 2.

Above-mentioned two tapered ends 2 that are connected at S shape twisted plate sheet insulation mandrel 1 two ends, be respectively relatively oppositely and be provided with, make two tapered ends 2 respectively be upper and lower reversion form, for combining with lead 3 lockings, because of tapered end 2 is one on the other inversion direction, cause the situation of beat twist so can improve two ends tapered end 2 that unbalances take place, two division conductor spacers are installed between two leads 3, can suppress the beat twist in order to keep the balance and stability of lead 3.

Shown in Fig. 8 embodiment, the utility model also can be provided with the one or more anti-hook 221 of waving in the outside half locking plate 22 of S shape twisted plate sheet insulation mandrel 1 two ends tapered end 2, make hook 221 can supply eccentric hammer (weight) to be suspended, amplitude when suppressing lead 3 by this and waving obtains the better anti-effect of waving.

Shown in the another kind of embodiment that Fig. 9 and Figure 10 disclosed, the alleged insulation mandrel 1 that is en plaque of the utility model, further also can be embodied as an insulation board lamellar body 1a who is the biconvex arc shape, in like manner, its structural strength is also splendid, can reduce wind area, and reduce the stressed degree of insulation gap rod; The outside half locking plate 22 of the insulation board lamellar body 1a two ends tapered end 2 of biconvex arc shape also can be established the one or more anti-hook 221 of waving, and is suspended for eccentric hammer (weight), reaches the purpose of improving conductor galloping.
