Description
Technical Field
The utility model relates to a sign for the electric power engineering especially relates to a 220kV cable generating line exempts from to demolish installation and prevents wind sign.
Background
The 220KV high-voltage bus in the transformer substation needs to be provided with a sign board because the overhead height is very low and the air discharge can be punctured in a short distance. Current sign passes through the connecting band snap-on the cable, and although the sign can unload partial wind-force during the wind-break, the sign sways the in-process under the wind-force effect, can drive connecting band wearing and tearing cable surface, if with the sign snap-on the cable, then the sign drives the cable and sways about as the impetus of wind-force, causes danger.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve above-mentioned technical problem, provide a sign is prevent wind in 220kV cable bus-bar demolishs-free installation, its connecting band wearing and tearing cable that both can avoid the sign, can avoid the sign again as the impetus of wind, can install under the condition of not tearing open the cable simultaneously.
The technical solution of the utility model is that:
220kV cable bus exempts from to demolish installation and prevent wind sign, including the sign, be equipped with two trompils of arranging about on sign upper portion, worn the connecting band respectively in two trompils departments, its special character lies in: the upper part of the connecting band is provided with a cable fixing sleeve extending along the left-right direction, the lower part of the cable fixing sleeve is provided with an opening A, the connecting band is hung on the cable fixing sleeve, the outer circular surface of the cable fixing sleeve is provided with two groups of limiting rings arranged left and right, and the connecting band passes through the corresponding side limiting rings; one end of the cable fixing sleeve is provided with a plurality of clamping pieces which are circumferentially arranged, the plurality of clamping pieces are sleeved with a locking sleeve, and the lower part of the locking sleeve is provided with an opening B.
Further preferably, the section of the clamping piece is circular arc.
Preferably, the outer circle surface of the clamping piece is provided with an external thread, the inner circle surface of the locking sleeve is provided with an internal thread, and the clamping piece is in threaded fit with the locking sleeve.
Preferably, the inner circle surface of the locking sleeve is wide in inner and narrow in outer, after the clamping piece is hooped by the locking sleeve, the outer end of the clamping piece is tightened, and the cable is tightly clamped by the clamping piece.
Preferably, the number of the limiting rings is three, one limiting ring is positioned at the top of the cable fixing sleeve, and the other two limiting rings are respectively arranged at the front side and the rear side of the cable fixing sleeve.
Preferably, the number of the clamping pieces is three, one clamping piece is positioned at the top of the cable fixing sleeve, and the other two limiting rings are respectively arranged at the front side and the rear side of the cable fixing sleeve.
The utility model has the advantages that:
the sign sways the in-process under wind-force effect, and the connecting band and the cable cover of sign take place relative slip, prevent that the connecting band from contacting the cable, prevent that the cable surface from taking place by the condition of wearing and tearing, and the sign uses the fixed cover of cable to be rotatory as the centre of a circle under wind-force effect, unloads wind-force, avoids wind-force to grab the impetus. Because the clamping piece at one end of the cable fixing sleeve is under the action of the locking sleeve hoop, the cable fixing sleeve is fastened on the cable, and the left-right sliding condition is avoided.
