Description
Technical field
The present invention relates to electric insulation bar pressure test technical field, particularly many insulating bars are carried out pressure examination simultaneously
The device tested.
Background technology
Specifying according to " electric power safety working regulation ", the insulating bar class security tool such as insulating bar, phasing tester need to be carried out every year
Pressure test, to verify its insulating properties.This is because insulating bar prolonged application is in on-the-spot hot line job, secondary along with using
Number increase inevitably occur aging, damage or make moist, its insulating properties also can decline to a great extent.If this type of is insulated
The bad insulating bar of performance is applied to on-the-spot hot line job, easily works the mischief user.Insulation aging, that damage or make moist
Bar is when bearing high-tension electricity, it may occur that insulating bar wear hit, flashover or the phenomenon such as overheated, therefore pressure test is that verification insulating bar is exhausted
The effective ways of edge performance.
In the pressure test of insulating bar, the voltage that one end applying code of tested insulating bar is specified, other end ground connection,
With during insulating bar pressure test without puncturing, be superheated to without flashover and nothing qualified.Traditional insulating bar pressure test can only be single
Root is carried out, and needs to carry out insulating bar live end and ground connection manual bare copper wire winding every time, is wound around and necessarily requires reliably, it is ensured that
Bare copper wire and insulating bar reliable contacts, otherwise test defective；Secondly, when experiment quantity is a lot of, mounting or dismounting bare copper wire frequently,
Very wasting time and energy, the hands of testing crew is the most often stabbed by the burr of bare copper wire.It addition, original assay device is by two
Insulation bench forms, and the distance at two ends is not fixed, and will measure, before starting to measure, the test distance taking corresponding voltage with a yardstick every time, lead
The test efficiency causing pressure test cannot improve.
Summary of the invention
It is an object of the invention to overcome the deficiency of current existing wiring technique, it is provided that one can meet simultaneously thoroughly does away with edge more
Bar pressure test, automatically carry out insulating bar earth terminal and live end wiring, pressure test distance is fixing, easy to operate, save time province
Many test apparatus for overpressure resistance of insulator spindles of power.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of many test apparatus for overpressure resistance of insulator spindles, including rectangle rustless steel base, be installed on base universal wheels below,
Be installed on the stainless-steel tubing pillar above four angles of base, the insulating bar pillar that can be inserted in stainless-steel tubing pillar, be installed on relative
Rustless steel rectangular tube that on two insulation columns one group is parallel to each other, it is installed on upright of every rustless steel rectangular tube two ends
Frame, the bearing block being installed on up-right support top and bearing thereof, it is positioned at above rustless steel rectangular tube and two ends are installed in bearing
Stainless pipe, the circular hole being arranged in pairs through a row of rustless steel rectangular tube up and down, be each passed through paired two circular hole
Rear joint connect formed one group of steel wire ring, two ends are connected to stainless pipe and one group of cord of steel wire ring, hang respectively
The pendant one group of cone weight in each steel wire ring bottom, it is installed on the hand cranking handle of stainless pipe outer end.
The present invention is provided with reverse dead lock in one end of stainless pipe.Stainless-steel tubing pillar and insulating bar pillar are by solid
Determine screw location fixing.The described pitch-row through paired two circular hole of rustless steel rectangular tube is 2cm, and Circularhole diameter is 3mm；
The steel wire diameter of steel wire ring is 2mm.
Whole assay device is fixed on base by the present invention, can fix pressure test distance, need not the most before measuring
The test distance taking corresponding voltage will be measured with a yardstick.Bottom of device installs universal wheel, adjusting position when being moved easily and test.
Apparatus of the present invention are used to do insulating bar pressure test, can be by insulating bar from stainless steel square after pulling up steel wire ring by cord
In shape pipe steel wire ring inserted above collar extension, insulating bar two ends to be tested are individually positioned in above the rustless steel rectangular tube of both sides
In steel wire ring collar extension, loosening cord, under the action of gravity of cone weight, steel wire ring is pulled downwardly tightly, is tightly pressed against insulation
On bar, cone weight, rustless steel rectangular tube and the cooperation through the steel wire ring of rustless steel square bar circular hole is utilized to realize steel
Silk and the reliable contacts of insulating bar, and then can directly carry out the pressure test of insulating bar.Due on a rustless steel rectangular tube
Many group steel wire ring is mounted side by side, it is possible to realize many insulating bars being carried out the wiring of pressure test and being tested simultaneously, work
It is greatly improved as efficiency.The stainless pipe locking that set reverse blocking device can will rotate in place, prevents it freely
Movable, it is ensured that the safety and reliability of test.The present invention by simple " a pull and a place one pine " be achieved that insulating bar with
Being reliably connected of steel wire, completes the steel wire winding of insulating bar, instead of prior art and is wound around the operation of bare copper wire on insulating bar,
It is no longer necessary to manual to be wound around bare copper wire, it is to avoid hands is wounded by stabbing.The present invention is easy and simple to handle, time saving and energy saving, is greatly improved test
Efficiency and reliability.
