Abstract
An annular screening ring for a metalware strain insulator-string relates to the technical field of machinery and electricity. The screening ring mainly consists of a ring body, a bracket and fasteners, wherein the outer end of the bracket is connected with the ring body through the fastener; and the fastener for connecting strain insulator-string metalware is arranged at the inner end of the bracket. In installation and use, a conducting wire bundle penetrates through the ring; the center and the gravity center of the ring body are on the same axial line with the center of the conducting wire bundle; and the conducting wire bundle vertically penetrates through the plane of the ring body and is surrounded. Because of the screening ring and the installation position, the ring body is stressed evenly, the corona-proof performance is good, repairs are reduced, energy is saved, and consumption is lowered. The led-out wire of the conducting wire bundle of the strain insulator-string can be positioned in any direction and connected through a jumper wire.
Description
Technical field
The utility model relates to the mechanical electric technical field.
Background technology
In traditional transmission line, the helix type structure that the strain insulator-string shading ring adopts.Its installation site in strain insulator gold utensil string is positioned at the bundle conductor left and right sides.Because its structure has determined that it is in the state operation of centre-of gravity shift all the time, be easy to produce fatigue deformation year in and year out, simultaneously in addition its in the installation site of strain insulator gold utensil string, affecting wire jumper can not connect in any direction, also may increase the probability of lead and shading ring vibration abrasion, influence the safe operation of power transmission and transformation line.
The utility model content
The utility model purpose is to design a kind of more reasonable structure, and mechanics, electric property are more excellent, more can guarantee power transmission and transformation line safe operation, few maintenance, shading ring easy for installation, as to improve anti-corona performance.
The utility model mainly is made up of torus, support and securing member, and the outer end of described support is connected with torus by securing member, and the inner is provided for connecting the securing member of strain insulator-string gold utensil.
Described torus can be combined as close ring by nipple by two semicircular ring, can be the integral finish ring of semi-round ball for the both ends that are provided with an opening also.
When installing and using, bundle conductor passes in encircling, and ring body center center of gravity and bundle conductor center are on same axis, and bundle conductor vertically passes through plane, torus place, is encircled.This shading ring and installation site, ring body is stressed evenly, and anti-corona performance is good, reduces maintenance, and is energy-saving and cost-reducing, and the lead-out wire of strain insulator-string bundle conductor is connected with wire jumper in any direction.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is that integral finish torus 1, support 2 and the securing member 3 of semi-round ball formed by being provided with an opening, both ends, the outer end of support 2 is connected with torus 1 by fastener 3, is positioned at the securing member 3 that is provided for connecting the strain insulator-string gold utensil on the support 2 at torus 1 center.
As shown in Figure 2, torus 1 is combined as close ring, other same Fig. 1 by two semicircular ring by the nipple 4 that the end is provided with.
