Description
First, technical field
The present invention relates to technical field of electric power, and in particular to a kind of 35kV and 110kV transformers routine test wiring cross box.
2nd, background technology
The transformer of long-term heavy-duty service is susceptible to failure, and common transformer fault has built-in electrical insulation aging, winding turns
Between short circuit etc..State Grid Corporation of China company standard Q/GDW1168-2013《Power transmission and transformation equipment state overhauling testing regulations》Regulation is right
The transformer of 110kV and 35kV needs the high-potting for periodically carrying out.Being needed when high-potting is carried out to transformer will experiment
The lead of instrument is connected on the sleeve pipe pile crown of each side of transformer, according to different pilot projects, changes its each side sleeve pipe pile crown
Connected mode.At present, traditional test method is to carry out the change of each side winding connection mode with test wire on the transformer,
Often conduct an experiment the change for being accomplished by climbing a time main transformer carrying out the mode of connection, therefore we have developed transformer routine test
Wiring cross box.
3rd, the content of the invention
The present invention provides a kind of 35kV and 110kV transformers routine test wiring cross box in view of the shortcomings of the prior art, and it is special
Levy and be：Cross box（1）In cuboid, cross box（1）Top set A groups（2）, B groups（3）, C groups（4）, D groups（5）, E groups
（6）Five groups of connector lugs pass through wire with five groups of connector lugs of sidepiece respectively（8）Turn on two-by-two, cross box（1）Side be provided with
Handle（7）.
The cross box（1）It is made up of insulating materials.
The cross box（1）It is made up of resin material.
Application method of the invention is：By test connection cross box top A groups（2）, B groups（3）, C groups（4）, D groups（5）、E
Group（6）Five groups of connector lugs are connected with the high pressure on transformer, middle pressure, low pressure connector lug respectively, B groups（3）, C groups（4）, D groups（5）、
E groups（6）First connector lug is connected with the high pressure on transformer, B groups（3）, C groups（4）, D groups（5）, E groups（6）Intermediate connection head
It is connected with the middle pressure on transformer, B groups（3）, C groups（4）, D groups（5）, E groups（6）Low pressure on 3rd connector lug and transformer
Connection, when high pressure is tested, by cross box（1）Corresponding middle pressure and low-voltage short-circuiting, just can be tested on side, in experiment
During middle pressure, by cross box（1）Corresponding high pressure and low-voltage short-circuiting on side, when low pressure is tested, by cross box（1）It is right on side
The medium and high pressure short circuit answered, operating personnel need not frequently climb electric pole wiring short circuit again in this experiment, reduce labour intensity.
The beneficial effects of the present invention are：
Reduce the number of times for climbing main transformer.
Transformer high-voltage routine test mainly has：Winding D.C. resistance, iron core folder insulaion resistance, each side winding resistance,
Winding insulation dielectric dissipation factor and capacitance, load ratio bridging switch inspection, winding deformation.For 110kV three-winding transformers
Transformer number of times statistics, altogether 12 times are climbed in items experiment.And after using the junction box, it is only necessary to climbing 2 times can just complete to become
Depressor high pressure routine test project.
The time that reduction works on the transformer.
When transformer high-voltage routine test is carried out, traditional test method is that the test wire of test apparatus is connected into change
On the corresponding each side sleeve pipe pile crown of depressor, while the requirement shorting stub according to each pilot project changes the wiring of other windings
Mode, after the completion of items experiment, removes test lead and shorting stub, then carry out the next item down pilot project.Above all of work,
Testing crew is all to carry out on the transformer.And after using the case, it is only necessary to transformer is climbed up by the test lead of the cross box
It is connected at each side sleeve pipe pile crown of transformer, the test lead of test apparatus is connected to the cross box on the ground during experiment
On, and change the mode of connection of each side on the cross box, greatly reduce the time for working on the transformer.
Improve operating efficiency and security.
Traditional test method wiring is all carried out on the transformer, and transformer is higher, and transformer top structure is answered
Miscellaneous, testing crew movement is difficult, and bushing pile crown is very high, and testing crew wiring is difficult, while bringing larger to experiment work
Danger.After using the cross box, the dangerous work of transformer top is transferred to ground to do, improves operating efficiency,
Reduce the danger of work.
The cross box stable performance, meets test specification, and all pilot projects change of transformer routine test connects
The work of line mode is all carried out on the ground, and staff does not need safety belt, while the also constraint without safety belt, solves
Night, in the danger of transformer top repairing work, improves the operating efficiency of testing crew, and main transformer high-potting works by original
Five people for coming, are reduced to three people.
