Abstract
The utility model discloses a high-voltage lead insulation bracket for a high-voltage test, which comprises an insulation supporting rod, insulation binding belts and insulation soft cushions; the cross section of the insulation supporting rod is in a circular shape, a wire clamping groove for fixing a test lead is arranged on the insulation supporting rod; both ends of the insulation supporting rod are respectively fixed with the insulation binding belt, one end of the insulation binding belt is fixed at the end of the insulation supporting rod and the other end is connected with a U-shaped hanging hook; both ends of the insulation supporting rod corresponding to the positions of the insulation binding belts are respectively provided with the insulation soft cushion. During use, the insulation supporting rod is horizontally placed outside a ceramic sleeve, the insulation binding belt winds a circle around a ceramic bottle, and the U-shaped hanging hook hooks the insulation supporting rod; and the lead used for test is arranged in the wire clamping groove of the insulation supporting rod. The high-voltage lead insulation bracket has the advantages of simple structure, easy manufacturing and low cost, and is safe and convenient to operate and use; after the insulation bracket is fixed, leads of any test can be arranged on the bracket; the bracket is safe and convenient to use, is firm and attractive after the lead is fixed, and can not affect the test result.
Description
Technical field
When relating to a kind of high-potting, supports the utility model the insulating support of high-voltage connection.
Background technology
At present, in power network, be that the primary equipment of transformer, switch, mutual inductor, lightning arrester or the like all will be done high-voltage test to its insulation, check the insulation status of primary equipment.The character of test generally is divided into two kinds: commissioning test (before just dress puts into operation) and preventive trial (cycle of connecing carries out deciding inspection).High-voltage test is divided into again: 1, megger test; 2, DC voltage withstand test; 3, ac voltage withstanding (be divided into again industrial frequency withstand voltage and frequency multiplication withstand voltage etc.) test; 4, exchange the dielectric loss test; 5, partial discharge test etc.Above-mentioned all tests all are to draw by test wire (high-voltage connection) from different test apparatuses to be connected to tested device and to test, because the trial voltage of being done generally all is higher than the working voltage of primary equipment, and when test requires very high to environmental baseline: as require high-voltage connection over the ground the insulation of (shell) to get well, so how high-voltage connection over the ground good insulation performance be to allow the testing crew pain in the neck most.Way in the past is: 1. with insulation rope or ambroin band high-voltage connection is hung up.1), in process of the test the shortcoming of doing like this is:, as the rope or insulation rubber and plastic band gets loose suddenly or the ambroin band is pulled apart of insulating, a, the fragile tested device of the unexpected ground connection of high-voltage connection, b, the fragile test apparatus of the unexpected ground connection of high-voltage connection, c, high-voltage connection ride over personnel and cause personal injury accidents on one's body.2), be affected by the external environment very greatly, make when big the high-voltage connection swing also big as wind, can have a strong impact on test result like this, also dangerous.2. high-voltage connection is tied up on the external insulation insulator of tested device.The shortcoming of makeing like this is: 1), tie up in overcoat insulation, can make high-voltage connection twine (testing regulations requires to forbid high-voltage connection to twine), 2), equipment long-time running external insulation sleeve has filth, the filthy contact also with high-voltage connection can have a strong impact on measurement result.
Summary of the invention
In order to eliminate hidden danger and the difficulty that above-mentioned reason is brought, the utility model supports the insulating support of high-voltage connection when a kind of high-potting of special use is provided, and this insulating support is applicable to the support of all high-voltage connections of any high-potting.
The technical scheme that solution the utility model problem is adopted is: it is made up of insulation strut, insulated binding band, insulation soft cushioning, and insulation strut adopts the epoxy resin enhancement mode glass fibre extubation tube of excellent performance as the major insulation material; The insulation strut xsect adopts circular, and is designed to scalable shape, and insulation strut is provided with the cable clamping interface of fixation test lead-in wire usefulness; Each fixes an insulated binding band scalable length and elastic the insulation strut two ends, and insulated binding band one end is fixed on the end of insulation strut, and the other end connects U-shaped hook; One insulation soft cushioning respectively is installed at insulation strut both ends and the corresponding position of insulated binding band.
The beneficial effects of the utility model are: simple in structure, make easily, and cheap, manipulate safe ready; After this insulating support fixed, the lead-in wire of which kind of test all can ride on the support; This support is safe and convenient, not only firmly but also attractive in appearance, also can not influence test findings simultaneously behind the anchor leg.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is the utility model user mode figure.
Embodiment
As shown in Figure 1, it is made up of insulation strut 1, insulated binding band 5, insulation soft cushioning 4, and insulation strut 1 adopts the epoxy resin enhancement mode glass fibre extubation tube of excellent performance as the major insulation material; Insulation strut 1 xsect adopts circular, and is designed to scalable shape, and insulation strut 1 is provided with the cable clamping interface 2 of fixation test lead-in wire usefulness; Each fixes insulated binding band 5 a scalable length and elastic insulation strut 1 two ends, and insulated binding band 5 one ends are fixed on the end of insulation strut 1, and the other end connects U-shaped hook 3; At about 20cm place, distance insulation strut 1 both ends, with insulated binding band 5 corresponding positions respectively install one the insulation soft cushioning 4.
During use: as shown in Figure 2,, regulate the length of insulation strut 1 according to the distance between electrical equipment two insulators 6; Insulation strut 1 is disposed across the outside of insulator 6, and has kept enough safe distances with ground or device housings; Allow the insulation soft cushioning 4 at insulation strut 1 two ends contact, prevent to cough up and hinder insulator 6 with insulator 6; Insulated binding band 5 around insulator after 6 one weeks, is hooked insulating bar with U-shaped hook 3 and props up 1 and both can; Test can ride in the cable clamping interface 2 that the anchor leg on the insulation strut 1 uses with lead-in wire, plays the effect of support test lead.
Claims (2)
1. high-potting high-voltage connection insulating support, it is characterized in that: it is made up of insulation strut, insulated binding band, insulation soft cushioning, the insulation strut xsect adopts circular, and is designed to scalable shape, and the insulation strut body of rod is provided with the cable clamping interface of fixation test lead-in wire usefulness; Each fixes an insulated binding band insulation strut two ends, and insulated binding band one end is fixed on the end of insulation strut, and the other end connects U-shaped hook; One insulation soft cushioning respectively is installed at insulation strut both ends and the corresponding position of insulated binding band.
