Abstract
The invention relates to a portable test wiring bench for a high-voltage test. The structure of the bench is characterized in that an insulating board is arranged in a box body; wiring insertion holes are formed in the insulating board; and high-voltage wire insertion holes are formed in side of the box body. Binding posts I and binding posts II are respectively arranged in the high-voltage wire insertion holes and the wiring insertion holes; insulators sleeve the outer surfaces of the binding posts I and the binding posts II; and bus bars are connected between the binding posts I and the binding posts II. According to the invention, all devices for items of the transformer commissioning test and the routine test are integrated to the test bench and thus integrated switching can be completed by one set of test wires so as to complete corresponding test items.
Description
Technical field
The present invention relates to a kind of testing table, particularly relate to the portable test connection platform of a kind of high-potting, be applicable to the commissioning test of 220kV transformer field and routine test, belong to electric power application.
Background technology
The test of 220kV transformer field has numerous pilot project, the different instrument and equipment of multiple stage usually will be used to test, in process of the test, repeatedly will change instrument and equipment, repeatedly change test connection.220kV high voltage side of transformer sleeve pipe and medium voltage side sleeve pipe very high, climb down transformer operate as testing crew will repeatedly be climbed up, this mode of operation not only labour intensity is large, on-the-spot chaotic, and is easy to occur security incident.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide the portable test connection platform of a kind of high-potting, solve the problem that labour intensity in prior art is large, there is potential safety hazard.
Technical scheme of the present invention is as follows:
Arrange insulcrete in casing, insulcrete is provided with patch jack; The side of casing arranges hi-line jack, and hi-line jack and patch jack are respectively equipped with binding post I and binding post II, the outside surface suit insulator of binding post I and binding post II; Connection bus row between binding post I and binding post II.
Described interior is provided with screen layer.
Described bus bar is capacitor type bus bar.
Be provided with above described casing and renovate.
The end face of described casing is provided with switching door.
The long 240mm of described casing, wide 200mm, high 160mm.
Described binding post I and binding post II is equipped with 8.
Advantageous effect of the present invention is as follows:
1, conventional transformer pilot project (straight resistance, no-load voltage ratio, low-voltage impedance, loaded switch, dielectric loss, insulation etc.) testing equipment is switched instrument integration of equipments to be configured in chamber by the present invention.Use test battery wiring to complete wiring comprehensively to switch, just can complete corresponding pilot project.Process of the test is simply orderly, and high-power transformer is climbed in a large amount of minimizing and bushing shell for transformer changes connection times and changes instrument number of times, greatly reduces the quantity of labour intensity minimizing testing crew, meets the requirement of experimental safe.
2, testing table is that portable construction is convenient to carrying and deposits.
3, configuration test handoff functionality, directly can hinder, no-load voltage ratio, low-voltage impedance, loaded switch, dielectric loss, the testing equipment such as insulation switch.Increase work efficiency, make work safer, quick.
4, reduce site test personnel labor intensity, eminence when reducing transformer field test is dropped, is got an electric shock and mis-wired risk, and greatly shorten working hours, significantly reduce a staff quantity, experimental safe is guaranteed.
5, casing alloy material makes, external box of microvave reliable ground, and box house adopts masking foil to shield, and reduces external interference source and makes measurement more accurate.In casing, bus bar adopts capacitor type busbar to prevent corona from avoiding impact to measure.
6, be provided with above described casing and renovate, be convenient to wiring; End face is provided with switching door, is convenient to deposit replacing testing equipment; Box sizes design experiences is demonstrate,proved, can by testing equipment effective integration, again reduced volume to greatest extent.
