Abstract

The utility model relates to a double loop overhead wire and a terminal rod combined with a cable, which is used for connecting an overhead wire and a cable terminal in a high-tension transmission line. The utility model is characterized in that the top end of a low rod of the double loop overhead wire and the terminal rod combined with a cable is connected with the middle part of a high rod via a fixed beam, three cross arms are arranged on the high rod, the fixed beam and the low rod from high to low in turn, cable terminals are arranged on both sides of the high rod and the low rod on a cable terminal platform, and both ends of each of the three cross arms are respectively connected with three-phase cable terminals through an insulator, a suspended lightning arrester and an overhead wire. The utility model has the advantages of compact structure, beautiful appearance, small occupation area and convenient maintenance and operation.

Description

Two times overhead wire combines terminal pole with cable

The utility model relates in a kind of ultra-high-tension power transmission line, is used for overhead transmission line and combines terminal pole with the joining two overhead wires that return of cable termination with cable.

In ultra-high-tension power transmission line (as 110KV), the overhead transmission line of urban periphal defence need by cable termination with enter intown cable and combine.At present, thisly generally adopt truss-like typing iron tower form in conjunction with terminal, this truss-like typing iron tower floor space is big, can't be arranged on easily on the limit, pavement and Lutao in urban district, simultaneously huge iron tower not only influences the appearance of the city, and makes troubles in the future maintenance, operation.

It is little that the purpose of this utility model provides a kind of floor space, and overhauling, move easily, the double loop overhead wire combines terminal pole with cable.

The technical solution of the utility model is, this pair time overhead wire combines terminal pole and comprises two electric poles that are arranged side by side with cable, a high bar and a low bar, the top of low bar connects by a built-in beam with the middle part of high bar, at high bar, on built-in beam and the low bar, be fixed with successively from high to low three be parallel to each other and with height, low bar and the vertical cross-arm of built-in beam, there is a cable terminal platform to be positioned at high bar and low bar bottom, on the cable terminal platform, two groups of threephase cable terminals are arranged in high bar and low bar both sides respectively, and the two ends of three cross-arms link by three-phase overhead wire and threephase cable terminals by insulator and suspended-type surge arrester and two groups of circuits respectively.

The utility model has the advantages that, owing to adopt one high and one low two electric poles to cooperate the structure of three cross-arms to connect two groups of circuits, make this pair return overhead wire and cable termination bar compact conformation, attractive in appearance, floor space is little, not limited by urban land, and overhaul, move conveniently.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a lateral plan of the present utility model.

As Fig. 1～shown in Figure 3, this pair time overhead wire combines terminal pole and comprises two electric poles that are arranged side by side with cable, a high bar 1 and a low bar 2, the top of low bar connects by a built-in beam 3 with the middle part of high bar, at high bar 1, on built-in beam 3 and the low bar 2, be fixed with successively from high to low three be parallel to each other and with height, low bar and the vertical cross-arm 4 of built-in beam, cable terminal platform 5 is positioned at high bar and low bar bottom, on the cable terminal platform, two groups of threephase cable terminals 6 are arranged in high bar and low bar both sides respectively, and the two ends of three cross-arms 4 link by three-phase overhead wire 9 and threephase cable terminals 6 by insulator 7 and suspended-type surge arrester 8 and two groups of circuits respectively.
