In many divisions ultra-high-tension power transmission line of electric power system, generally just install one and divide damping conductor spacer every 50 or 60 meters, suppress the aeolian vibration and the subspan oscillation of high-voltage conducting wires with this, guarantee the safe operation of electric power system.The division damping conductor spacer has binary fission, tripartition, quadripartion, six divisions and eight divisions not to wait, and that the tripartition damping conductor spacer also is to use is more a kind of, existing tripartition damping conductor spacer be by on the Atria summit promptly three angles connecting hole is set respectively, outside connecting hole, also is provided with two frameworks of an oval location hole, and connect by the connecting hole bolt that an afterbody protrudes and the wire clamp main body of bag casting stainless steel bar, and be provided with between online clip main body and the framework that block rubber constitutes.Though this conductor spacer can play at interval and supporting role lead, but because under specific weather condition, transmission line can produce icing and accumulated snow, and along with the unprecedented expansion of China's hydroelectric resources exploitation scale, the wire icing of transmission line snow problem in high humidity, high area above sea level is more and more outstanding.Icing often causes the lead vibration, waves, and then occurs breaking, falling tower when serious, brings serious harm for the safe operation of electric power system.In order to reduce the harm that the ice and snow disaster is brought to electric power system, units concerned have researched and developed multiple division electricity transmission line charged (being on-load) ice melting scheme, and the enforcement of this scheme must adopt a kind of damping conductor spacer of insulation to realize.Yet present domestic its framework of division damping conductor spacer all adopts metal material to make, and the conductor spacer on all multiple division electricity transmission lines all conducts electricity, and can't satisfy the demand of charged molten ice at all, causes this scheme to implement.And the damping joint of existing tripartition damping conductor spacer location is to take the elliptical aperture of wire clamp main body afterbody bag casting stainless steel bar and framework to position, and its locate mode is not ideal enough, installs also cumbersome.
Summary of the invention:
The purpose of this invention is to provide a kind of trifid insulated damping conductor spacer, mainly solving present domestic its framework of division damping conductor spacer is that metal material is made, because conduction can't realize the charged molten ice of transmission line, and unfavorable problem is located in the damping joint of tripartition damping conductor spacer.
The present invention program is as described below: this invention comprises triangular framing, wire clamp main body, block rubber, connecting bolt, it is that framework is adopted the fiberglass manufacturing, outside inboard each connecting hole of framework, be arranged with the projective table type position block in the inner part, and establish the wire clamp main body that has the wire clamp formation that connects the joint.
Beneficial effect of the present invention: because the framework that this invention has taked fiberglass to make, can not only reliably isolate support to the tripartition lead, and has a good insulation performance effect, make mutually insulated between three leads, thereby created sufficient and necessary condition, the serious harm that reduces and avoided the ice and snow disaster to bring for the charged molten ice of transmission line to electric power system.And effectively increased the bearing strength of division conductor spacer.Also because this invention has taked to be provided with position block and improved wire clamp main body on framework, get the location structure of the elliptical aperture that has replaced wire clamp main body afterbody bag casting stainless steel bar and framework, add the combination of block rubber, changed traditional location structure mode, and in simplified structure, more increased the centripetal force of conductor spacer, produced beyond thought technique effect, make by framework, the damping pass that block rubber and wire clamp main body constitute is energy-conservation moves along with the motion of lead all the time, guarantees that lead all has damping action and good location when moving in any possible scope.Moreover, this invention also has novel, simple in structure, advantages such as making easily, dependable performance, cheap, economical and practical, easy for installation, suitable popularization, suitable icing district use.
