Abstract
A damper for an electric power line relates to a damper for a power transmission line. The damper for electric power line comprises a steel strand, a chuck main body and a chuck gland, wherein a lower end of the chuck main body is connected with the steel strand; two ends of the steel strand are respectively connected with a bell-type hammer made of a non-magnetic zinc alloy material; a lower end of the chuck main body is hinged to the chuck gland; a middle lower portion of the chuck main body is connected with the chuck gland through a pin baffle and a cotter pin; rubber tile gasket installation grooves are dispose on opposite surfaces of the chuck main body and the chuck gland respectively; the inside of each rubber tile gasket installation groove is connected with a rubber tile gasket; wire slots are disposed on opposite surfaces of the two rubber tile gaskets. The damper mainly adopts an integral type wire clamp body and the chuck gland which are hinged to form an integral hinged type chuck so as to enable the installation to be very simple; the damper is provided with rubber tile gaskets so that the damper can effectively protect surfaces of lead wires from any damage, and guarantee the chuck does not slip after being clamped with the wire clamp.
Description
Technical field
The utility model relates to a kind of used for transmission line stockbridge damper, relates in particular to a kind of coverage that can improve resonance frequency and improves the stockbridge damper that anti-corona performance can prevent again slippage.
Background technology
The effect of the external force such as the long-term wind-engaging of the wire of overhead transmission line, ice, corona can cause periodic vibration.Wire is under the vibrational state for a long time will cause vibrating fatigue, make the operation of circuit have very large potential safety hazard.Method commonly used is to install stockbridge damper additional to prevent its vibration at cable now, the excited frequency of being subjected to is narrow, power consumption is low but because common stockbridge damper has, when running into complicated weather conditions, often can not really embody the circuit vibration-isolating effect, greatly shorten the circuit operation time limit; Secondly, the most employing by the tightening chuck bolt of stockbridge damper makes the chuck briquetting compress wire, and clamper main body directly contacts with wire with the chuck briquetting, and the meeting damage wires is become flexible so that stockbridge damper produces in the use procedure, and slippage occurs.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of coverage that can improve resonance frequency to improve the damper for electric power line that anti-corona performance can prevent again slippage.
The purpose of this utility model is achieved in that a kind of damper for electric power line, comprise steel strand wire, clamper main body and chuck gland, the lower end of clamper main body is connected with steel strand wire, and the two ends of described steel strand wire connect respectively the clock-type tup of making without the magnetic zinc alloy material; The upper end of described clamper main body is hinged the chuck gland, and the middle and lower part of clamper main body is connected with the chuck gland by pin baffle, split pin; The forward surface of described clamper main body and chuck gland arranges respectively rubber tile pad mounting groove, connects respectively the rubber tile pad in each rubber tile pad mounting groove, and wire casing is set respectively on the forward surface of two rubber tile pads.
Be respectively equipped with the rubber tile pad in clamper main body of the present utility model and the chuck gland, the stressed rear clamping wire of rubber tile pad.Be provided with baffle pin and split pin below in wire clip body, the below crimping of wire clip body is steel strand wire fixedly, and the two ends of steel strand wire with after the crimping of aluminium cover, are riveted on the interior end of tup respectively again, then fix with epoxy resin or low-melting alloy pouring.Anti-vibration hammer is the clock-type structure of making without the magnetic zinc alloy material, can increase the anticorona performance of stockbridge damper.
Stockbridge damper of the present utility model has mainly adopted all-in-one-piece wire clip body and chuck gland; they are hinged to make installation very easy for holistic hinge type chuck; and be provided with effectively guardwire surperficial without any damage of rubber tile pad, and guarantee that chuck and wire clamp clamp afterwards without slippage.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Embodiment
As shown in Figure 1, 2, be damper for electric power line, comprise clamper main body 1, the upper end of clamper main body 1 is hinged chuck gland 2 by hinge 3, and the middle and lower part of clamper main body 1 is connected with chuck gland 2 by pin baffle 5, split pin 8.The forward surface of clamper main body 1 and chuck gland 2 arranges respectively rubber tile pad mounting groove 9, and each rubber tile pad mounting groove 9 is interior to be connected respectively on the forward surface of 4, two rubber tile pads 4 of rubber tile pad wire casing 10 is set respectively.The lower end of clamper main body 1 connects steel strand wire 6, and the two ends of steel strand wire 6 connect respectively the clock-type tup 7 of making without the magnetic zinc alloy material.
During installation, chuck gland 2 is opened, and directly hangs wire, close clinch ear gland 2 after, insert pin baffle 5 and split pin 8, make the rubber tile pad 4 stressed rear clamping wires in clamper main body 1 and the chuck gland 2, reach skidproof effect.Anti-vibration hammer 7 is the clock-type structure of making without the magnetic zinc alloy material, can significantly increase the anticorona performance of stockbridge damper.The two ends of steel strand wire 6 with after the crimping of aluminium cover, are riveted on the interior end of tup respectively again, and are then fixing with epoxy resin or low-melting alloy pouring.
Claims (1)
