Description

Binary fission sub-conductor all insulation damping conductor spacer
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to the single-phase ice-melt of a kind of 220kV of can be used for binary fission transmission line and the binary fission sub-conductor all insulation damping conductor spacer of Shu Tongxin mutually.
Background technology
In China 220kV binary fission transmission line of alternation current, the 40-100 rice of being separated by in each span will be installed a binary fission conductor spacer, be used for keeping the spacing of two root leads and will suppress aeolian vibration, the vibration of inferior span, to guarantee the safe operation of transmission line.But existing binary fission conductor spacer is made of the metal vaulting pole of two ends dribbling head and the wire clamp of dribbling nest.Because described conductor spacer is the all-metal manufacturing, and does not inlay block rubber in wire clamp, it can only play supporting role at interval to the binary fission lead, can not keep the insulation between two root leads, and the performance of eliminating conductor vibration is also very poor.
During 220kV binary fission transmission pressure icing, need carry out ice-melt to transmission line, owing to be subjected to the restriction of ice-melt power supply capacity, need be by carrying out mutually during ice-melt, or the 220kV transmission line is used for communication between the binary fission bundle conductor, when being called for short " phase Shu Tongxin ", must adopt a kind of making to keep the damping conductor spacer of insulation to realize between the binary fission sub-conductor.Yet, present its framework of binary fission conductor spacer and wire clamp all adopt metal material to make, namely the conductor spacer on all binary fission transmission pressures all conducts electricity, and very easily causes the electric short circuit between two root leads in the use, causes between the binary fission sub-conductor ice-melt and restraints communication interruption mutually.Therefore, a kind of damping conductor spacer that keeps insulation that can make between the binary fission sub-conductor of development is to realize the single-phase ice-melt of 220kV transmission line and the necessary condition of Shu Tongxin mutually.
Summary of the invention
The technical problem to be solved in the present invention is, at the defective that existing common binary fission conductor spacer exists, provides the single-phase ice-melt of a kind of 220kV of can be used for transmission line and the binary fission sub-conductor all insulation damping conductor spacer of Shu Tongxin mutually.Not only make the ice-melt of single-phase binary fission sub-conductor become possibility with Shu Tongxin mutually thus, can also produce damping action to conductor vibration, thereby transmission line resistance ice and snow disaster ability is restrainted communication quality mutually with lead, inhibition conductor vibration tool has very great help to promoting.
Technical scheme of the present invention is that referring to Fig. 1, the binary fission sub-conductor all insulation damping conductor spacer that provides is connected to form by glass fibre reinforced plastic insulating framework 1, position block 2, stopper slot 3, bolt 4, wire clamp 5, block rubber 6 as shown in Figure 1.Wherein said glass fibre reinforced plastic insulating framework 1 is the two frameworks of " V " font.Be connected by described bolt 4 between glass fibre reinforced plastic insulating framework 1 and the described wire clamp 5.Outside described glass fibre reinforced plastic insulating framework 1 inboard connecting hole, be that symmetric points arrange oval stopper slot 3 with the connecting hole, outside stopper slot 3, be symmetrical arranged position block 2 in the inner part.Described block rubber 6 is embedded in the wire clamp 5.
The binary fission sub-conductor all insulation damping conductor spacer of the present invention of Gou Chenging thus, because adopting wire clamp 5 ends that are inlaid with block rubber 6 locatees with the position block 2 on the glass fibre reinforced plastic insulating framework 1, add at 1 liang of connecting hole of glass fibre reinforced plastic insulating framework and through bolt 4 wire clamp 5, stopper slot 3 and glass fibre reinforced plastic insulating framework 1 are connected, also claim the damping joint herein, can be moved along with the motion of lead all the time in the damping joint, guarantee that lead all has damping action and good location in any position, thereby suppress the vibration of transmission pressure, avoid the fatigue wear of lead.
During implementing, the glass fibre reinforced plastic insulating framework 1 of binary fission sub-conductor all insulation damping conductor spacer of the present invention adopt the high voltage bearing fiberglass of high strength to make, because this glass fibre reinforced plastic insulating framework 1 is the two frame structures of " V " font, not only increased the centripetal force of binary fission sub-conductor all insulation damping conductor spacer, also be separated from each other between two root leads with the every phase of 220kV transmission line, avoid causing in the conductor spacer installation site short circuit of sub-conductor on electric, when needs carry out ice-melt or utilize the binary fission lead to carry out phase Shu Tongxin single-phase binary fission lead, open the isolating switch that is contained in the circuit two ends, make two root leads switch to series connection from parallel connection, guarantee the ice-melt of binary fission lead and carrying out smoothly of Shu Tongxin mutually.
The invention has the beneficial effects as follows:
1, for realizing between the single-phase binary fission sub-conductor in 220kV transmission line of alternation current that ice-melt created condition with Shu Tongxin mutually;
2, Insulating frame 1 is the two frame structures of " V " font, and centripetal force is big, can avoid between the binary fission sub-conductor expansionary force that conductor spacer is broken; The damping pass that it constitutes is energy-conservation moves along with the motion of lead all the time, guarantees that lead all possesses damping action and good location in any position;
3, the damping characteristic in damping joint can consume the energy that vibration produces, and suppresses the vibration of lead, avoids the fatigue wear of lead;
4, good insulation preformance, mechanical strength height, high frequency performance is good, distributed capacitance is little;
5, simple in structure, make things convenient for processing and manufacturing, economical and practical, easy for installation;
6, be convenient to be generalized on other many oidiospores lead all insulation damping conductor spacers and use.
