Abstract
The invention discloses an insulating bracket for supporting a high-voltage lead, comprising an insulating upright rod, a lead supporting rod and an I-shaped pedestal slot, wherein the lead supporting rod is arranged at the top of the insulating upright rod and vertical to the insulating upright rod; a lead slot is arranged on the upper plane of the lead supporting rod; a mounting sleeve is arranged on the upper plane of the I-shaped pedestal slot; the insulating upright rod is inserted in the mounting sleeved and fixed by a jack screw on the mounting sleeve; a screw rod with a manipulation handle is arranged at the upper edge of the I-shaped pedestal groove; and a pressure plate is arranged at the lower end of the screw rod. The insulating bracket for supporting the high-voltage lead has simple structure, is easy to manufacture and convenient to operate, and is safe and reliable; once the insulating bracket is fixed well, the lead for any test can be fixed on the bracket; and after being fixed, the lead is firm and attractive without influencing the test result. Therefore, the insulating bracket for supporting the high-voltage lead can overcome all the problems in the prior art.
Description
Technical field
Support the insulating support of high-voltage connection when the present invention relates to a kind of high-potting.
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, support the insulating support of high-voltage connection when the invention provides a kind of high-potting of special use, this insulating support is applicable to the support of all high-voltage connections of any high-potting.
Solving the technical scheme that problem of the present invention adopted is: this insulating support is made up of insulation vertical rod, lead-in wire support bar, I shape base draw-in groove, it is vertical with the insulation vertical rod that the lead-in wire support bar is located at insulating vertical masthead portion, is being provided with cable clamping interface on the plane on the lead-in wire support bar; The plane is provided with an installation sleeve on the I shape base draw-in groove, and the insulation vertical rod is inserted in the installation sleeve, is fixed by the jackscrew on the installation sleeve; Limit portion is provided with the screw mandrel of a band lever on I shape base draw-in groove, and end, screw mandrel lower end has a pressing plate.
For being convenient for carrying, vertically insulated vertical rod is provided with a bracket in insulating vertical masthead portion, and lead-in wire support bar one end is connected bracket one end through a little rotating shaft, and can carry out 270 degree upsets around little rotating shaft.
Be the convenient height of adjusting, the insulation vertical rod is a telescopic rod.
For making I shape base draw-in groove and device housings fixing more firm, the corresponding Position Design of pressing plate inboard and below the screw mandrel is a zigzag below I shape base draw-in groove.
The invention has the beneficial effects as follows: simple in structure, make easily, easy to operate; In case this insulating support fixes, 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, can overcome all problems that prior art exists.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The present invention as shown in drawings, it is made up of insulation vertical rod 4, lead-in wire support bar 2, I shape base draw-in groove 7, the epoxy resin enhancement mode glass fibre extubation tube that excellent performance is adopted in insulation vertical rod 4 is as the major insulation material, and insulation vertical rod 4 xsects adopt circular, and are designed to telescopic; Be provided with a bracket 3 at insulation vertical rod 4 tops perpendicular to the insulation vertical rod, lead-in wire support bar 2 one ends are connected bracket 3 one ends through a little rotating shaft, and can carry out 270 degree upsets around little rotating shaft, time spent lead-in wire support bar 2 is not attached to insulation vertical rod 4 sides and insulation vertical rod 4 maintenance balances, be easy to carry, upset lead-in wire support bar 2 is to the 4 one-tenth an angle of 90 degrees in bracket 3 places and insulation vertical rod during use.Design has at least two cable clamping interfaces 1 on plane on the lead-in wire support bar 2, goes between in order to fixation test.I shape base draw-in groove 7 adopts metal materials to make, and last plane is provided with an installation sleeve 5, and insulation vertical rod 4 is inserted in the installation sleeve 5, can 360 degree rotations installation sleeve 5 in, adjust angle after, fix by the jackscrew on the installation sleeve 56; Limit portion is provided with the screw mandrel 9 of a band lever on I shape base draw-in groove 7, end, screw mandrel 9 lower end has a pressing plate 10, for making I shape base draw-in groove 7 and device housings fixing more firm, inboard pressing plate 10 corresponding Position Design below screw mandrel 9 are zigzag 8 below I shape base draw-in groove 7.During use, I shape base draw-in groove 7 is stuck on primary equipment framework or the primary equipment shell,, screws lever as plane on the transformer and outer bell jar junction, adjust the angle of lead-in wire support bar 2 after, fix by the jackscrew on the installation sleeve 56 vertical rod 4 of will insulating; In case this insulating support fixes, the lead-in wire of which kind of test all can ride on the insulating support, is stuck in cable clamping interface 1 internal fixation.
