Description
Technical field
The utility model is related to a kind of downlead device, more particularly, to a kind of downlead for transformer fast-wiring
Device.Belong to power system transformer electrical test field.
Background technology
The electrical test of high-power transformer is related to numerous pilot projects.By taking 220kV main transformers as an example, the insulated electro of winding
The test of resistance, absorptance and polarization index, winding D.C. resistance are tested, winding insulation dissipation factor test, condenser bushing
Dielectric dissipation factor and capacitance test, voltage ratio test and winding deformation test etc..And when these tests are carried out,
Then there is following shortcoming：
1st, the p-wire that traditional experiment is provided using producer, the p-wire section are little, and resistance itself is big, and measuring accuracy is not inconsistent
Close and require；
2nd, the test line length that large-scale power transformer producer provides is inadequate, also without special downlead, the data of measurement
Dispersed big, error is big, increases analysis difficult judgment；
3rd, in traditional large-scale power transformer process of the test, due to connecting the sleeve pipe excessive height of bus, maintenance and height
Pressure testing crew needs repeatedly climbing sleeve pipe to change test connection, increases personal height and falls danger coefficient；
4th, testing efficiency is low, it is impossible to complete test mission according to plan, adds
Loose contact, needs maintenance and affects the testing time；
Therefore, the electrical test precision of high-power transformer should be ensured, solution testing crew is repeatedly ascended a height and changes examination again
The relatively hazardous problem of wiring is tested, and great worry is brought to the worker of power system transformer electrical test.
Content of the invention
The utility model provide to solve the above problems a kind of for during solving high-power transformer electrical test,
Staff ascend a height change test connection in occur dangerous, efficiency is low, the difficult problem that physical demands is big, realizes high-power transformer
The quick downlead of wiring, be effectively reduced testing crew ascend a height wiring number of times a kind of drawing for transformer fast-wiring
Coil inserting apparatus.
In order to solve above-mentioned technical problem, the utility model is achieved through the following technical solutions：
For the downlead device of transformer fast-wiring, including test connection folder, the voltage by wrapped with insulation
Line, electric current line and insulated nylon rope, its are that test connection folder middle part adapting position is provided with copper bar, and the copper bar passes through bolt and nut
Form be connected with electric current line and pressure-wire respectively, the outside of electric current line and pressure-wire is provided with insulating sleeve, and electric current line and
Pressure-wire is leant out from insulating sleeve afterbody, and the adapting position of the insulating sleeve lower end is additionally provided with insulated nylon rope.
Described copper bar is not less than 300 amperes of copper bar using current-carrying capacity.
Described voltage cross-sectional area is not less than 16mm2Insulated conductor.
Described electric current cross-sectional area is not less than 25mm2Insulated conductor.
Described test connection folder is metal material.
When the major function of the utility model pressure-wire and electric current line is to carry out D.C. resistance etc. to test to transformer, can be by
Pressure-wire causes transformer lower end with electric current line, is directly connected to test apparatus.When transformer is needed three-phase shortcircuit, also can be
Transformer lower end is carried out, and climbs sleeve pipe without the need for testing crew.Pressure-wire uses wrapped with insulation with electric current line, to ensure each other
Mutually insulated.
The major function of insulated nylon rope is fixed voltage line and electric current line, prevents in process of the test, due to pressure-wire with
Electric current line hangs in the sky, and causes test connection folder connection not firm, affects result of the test.
Due to adopting above-mentioned technical proposal so that the utility model has reached following technique effect：
The utility model is clipped on bushing shell for transformer lead connection row by test connection, and pressure-wire is drawn with electric current line
To transformer lower end, make testing crew be tested in transformer lower end, and change test connection.After off-test, examination
The personnel of testing can need to be only dismountable device using insulating bar without climbing sleeve pipe.The utility model is meeting test accuracy
In the case of, the number of times that test connection changed by testing crew climbing sleeve pipe is significantly reduced, is reduced to only needing several times by former ten
Climbing once, improves the efficiency of experiment work, and the danger of high falling when it also avoid changing test connection, so as to protect
The safety of wiring personnel is demonstrate,proved.
The utility model preferably meets test requirements document, is convenient test wiring and the auxiliary dress for improving test safety
Put.And having easy to carry, multi-pass operation saves time, laborsaving, changes wiring fast power-saving, and safe and reliable.Effectively reduce
Testing crew climbing sleeve pipe changes the number of times of test connection, improves operating efficiency, makes testing crew change easy-to-connect, maximum
Limit ensure that testing crew personal safety, preferably achieves on the premise of guarantee test accuracy, greatly improves
Operating efficiency and safety coefficient.
