7 meters of high, medium and low voltage three side maximum distance.Then carry out wiring, testing high voltage dielectric loss over the ground it is contemplated that personnel with set
The factor (220kv is 3 meters, 110kv is 1.5 meters, 35kv is 1 meter) of standby safe distance, wiring workman must be from 6 meters of high transformations
Get off on device, guarantee personal safety.Press in test that dielectric loss is also same process over the ground with low pressure over the ground, additionally
There is the sleeve pipe medium loss test of high and medium voltage, only one project of test is accomplished by climbing up and climbs down 12 times, and multiple climbing was both prolonged
Grow test period, increased personal security hidden danger simultaneously again.It is thus desirable to one kind can improve work efficiency, to greatest extent
The protection person and equipment safety, implement the device of State Overhaul Test code comprehensively.
Content of the invention
The present invention is to need ceaselessly transformer connection up and down to lead to work efficiency not in the test solve current transformator
Technical problem that is high and there is potential safety hazard, provides a kind of transformer synthesis test box.
The present invention adopts the following technical scheme that a kind of realization: transformer synthesis test box, including a test casing,
The front panel of casing is provided with high, medium and low compression leg, and the back panel of casing also is provided with high, medium and low compression leg；On two panels
All it is connected by testing box house connecting line between high-pressure column, between middle compression leg and between lower pressure column；Test casing
Front and the back side are equipped with above this binding post maskable of a drawing and pulling type corresponding to each high, medium and low compression leg and a left side
The radome of right both sides.
The present invention, according to the joint categories of test lead, makes corresponding connecting interface, by test lead used
Joint converges in a special connecting box.Front panel or back panel are connected with transformator；Then another panel
Just can be connected with test instrunment；Using one by one, accomplish correspond；Casing is located at outside safe distance, changes and surveys
Test instrument or be connected with transformator wiring when it is not necessary to climb up transformator again it is only necessary to change wiring by the casing
Can.Insulation aspect is isolated using radome, when measuring, radome is pulled out a part, by each binding post with
Neighbouring binding post shielding, keeps stable insulation.For the difference of pilot project during transformer test, need frequently to change
Wiring, carries out disposable wiring by the present invention and reduces the number of times raising work efficiency of wiring and the accurate of test to transformator
Property.The connected mode of the arrangement of the binding post on high, medium and low compression leg and inside is the public affairs of those skilled in the art
Know technology, those skilled in the art just could be aware that its implementation after reading this Shen feelings file.
Using after this device, when main transformer is tested, decrease climbing number of times, shorten test period, reduce people simultaneously again
Member's potential safety hazard.Improve work efficiency, protect the person and equipment safety to greatest extent.This device also have small volume,
The features such as wiring is simple.
