Description
[technical field]
The utility model is a kind of high-voltage transmission line insulator leakage current collector ring, is used for convection current and crosses the leakage current of ultra-high-tension power transmission line insulator surface and collect.
[background technology]
To the monitoring of high-voltage transmission line insulator filth, mainly be the pollution level that the leakage current that utilizes working voltage to monitor every phase insulator (string) reacts insulator; Filthy serious, then leakage current is big, and filthy light, then leakage current is little.The usual means of utilizing said method to monitor is that collector ring is installed on insulator, existing a kind of collector ring is collector ring to be supported on the steel cap of insulator by the supporting screw on its hard ring body, the current collection line pressure holding that makes the ring body lower surface is on the insulating boot of insulator, has unlimited slit between its ring body and the insulator steel cap, easily shelter evil people and countenance evil practices rainproof anti-filthy poor performance; The existence of these unfavorable factors causes collector ring itself to become the reason that reduces the insulator dielectric performance.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective that existing product exists, provide a kind of rainproof anti-filthy performance strong high-voltage transmission line insulator leakage current collector ring, with when the high-voltage transmission line insulator filth is normally monitored, do not influence the insulating property of insulator.For this reason, the utility model is taked following technical proposals:
A kind of high-voltage transmission line insulator leakage current collector ring, comprise elastic insulated ring and current collection line, there is holding tank the lower surface that it is characterized in that described dead ring, current collection line is positioned at holding tank and protrudes from the dead ring lower surface, press on the described dead ring and establish elasticity extruding circle, entertain anchor ear on the extruding circle; Also be provided with the joint that links to each other with described current collection line on the described dead ring.During use, successively dead ring and extruding snare are contained on the steel cap of insulator, to push circle with anchor ear again holds tightly on the steel cap of insulator, because the extruding circle has elasticity, the extruding circle of being held tightly is out of shape and axially (perpendicular to the direction of dead ring upper surface) extension of generation, thereby dead ring is fixed on the insulator reliably, and the current collection line pressure holding that makes the collector ring lower surface is on the insulating boot of insulator.This structure has been eliminated the hard ring body of existing structure and the unlimited slit between the insulator steel cap, has stronger rainproof anti-filth (deposition or accumulation) performance, when the high-voltage transmission line insulator filth is normally monitored, can not reduce the insulating property of insulator.
As the further of technique scheme improved and replenish, can take following concrete measure:
Described dead ring forms the installation when easy to use by two semicircle ring bodies by tenon and the tongue-and-groove interlocking that its end cooperatively interacts.
Described current collection line is the net metal line that is woven into, to possess the effect of good collection leakage current.
Offer annular groove on the inwall of described extruding circle, to increase the distortion of pushing circle and to strengthen the sealing of pushing between circle and the insulator stylolitic part.
The lower surface of described dead ring is interior short outer high circular step face, described holding tank be positioned at the dead ring lower surface edge so that the umbrella of the lower surface of this dead ring and insulator partly matches.
Described extruding circle has angle, is convenient to anchor ear it is embraced tightly on the stylolitic part of insulator.
The utility model is simple in structure, is easy to install, and has stronger rainproof anti-filth (deposition or accumulation) performance, when the high-voltage transmission line insulator filth is normally monitored, can not reduce the insulating property of insulator.Owing to adopt the elastic insulated ring of silicon rubber, be applicable to the insulator of different taperings, and guarantee that contact is tight that drainage effect is better.

[embodiment]
Collector ring as shown in Figure 1 is made up of elastic insulated ring 3, current collection line 2, elasticity extruding circle 6, anchor ear 5 and joint 4, wherein:
Elastic insulated ring 3 is to form (seeing Fig. 2,3,4) by two semicircle ring bodies that silicon rubber is made by tenon 10 and tongue-and-groove 11 interlockings that the ring body end cooperatively interacts, have good insulation performance performance and elastic deformability, the external diameter of its internal diameter and insulator steel cap 7 is suitable, its upper surface is the plane, the lower surface is interior short outer high circular step face, offers holding tank 9 at the outer rim place of contiguous ring-type step surface;
The silver-plated net metal line of current collection line 2 for being woven into, its center is filled with the soft rubber thing; Be positioned at holding tank 9;
Elasticity extruding circle 6 offers annular groove 8 for offering the rubber ring of angular cut 12 on its inwall, the external diameter of internal diameter and insulator steel cap 7 is suitable, is pressed on (see figure 5) on the upper surface of dead ring 3;
The endless loop of anchor ear 5 for tightening up embraced on the cylindrical of extruding circle 6;
Joint 4 is the Q9 joint, is fixed on the upper surface of dead ring 3, and links to each other with current collection line 2 by lead.
During use, successively dead ring 3 and extruding circle 6 are sleeved on the steel cap 7 of insulator, current collection line 2 is contacted with the back side of insulator dielectric cover 1 (porcelain vase or cloche), extruding circle 6 is pressed on the dead ring 3, to push circle with anchor ear 5 again holds tightly on the steel cap of insulator, because the extruding circle is flexible, the extruding circle of being held tightly is out of shape and axially (perpendicular to the direction of dead ring upper surface) extension of generation, thereby be fixed on dead ring on the insulator reliably, and the tight pressure holding of the current collection line that makes the collector ring lower surface is on the back side of insulating boot, the flow through leakage current on insulating boot two sides of collection prevents that simultaneously the rainwater filth from immersing along the steel cap; Be connected on the Q9 joint with transmission cable, cause on the monitoring main frame, carry out on-line real time monitoring.
