Background technology
Being surpassed, the high-voltage test of extra-high voltage alternating current-direct current transformer and reactor when, often due to the experiment of test product
Voltage class is too high, it is necessary to add grading ring or grading shield to meet test requirements document on the outlet terminal of test product.In order to test conveniently,
Typically pressed in the form of grading ring.Existing grading ring erection sequence is：First, transformer connecting terminal is removed；
2nd, grading ring is sleeved on transformer terminal；3rd, transformer connecting terminal is arranged on outlet terminal again and is pressed
Tightly.But when test connection is carried out, this kind of transformer grading ring easily loosens, and wiring is more difficult, easily goes out in process of the test
The problems such as now disturbing, while there is also certain potential safety hazard.In order to reduce wiring complexity, improve production efficiency is ensured
Being smoothed out for transformer test, is badly in need of a kind of new super, extra-high voltage transformer binding post of design to meet the peace of grading ring
Dress.
The content of the invention
Regarding to the issue above, the present invention provides a kind of grading ring special wiring terminal.
To solve the above problems, the technical solution adopted by the present invention is：A kind of grading ring special wiring terminal, including it is symmetrical
The binding post I and binding post II of setting, its middle connecting terminal I include terminal plate I and the Ω types being connected with the lower end of terminal plate I
Terminals I, are placed with bolt hole A on the described panel of terminal plate I, a side of bolt hole A downsides terminal plate I is horizontally arranged with
Rectangular channel I, the described upper end of Ω types terminals I is connected by level connection joint panel with the lower end of terminal plate I, I liang of Ω types terminals
It is separately provided for stepping up the bolt hole B of high pressure phase line outlet terminal on side panel, and the both sides panel of Ω types terminals I is equal
It is parallel with terminal plate I.
Described binding post I and binding post II is fastened by bolt passing through bolt hole B, makes binding post I and wiring
After terminal II is docked, Ω types terminals I constitute tubular with Ω types terminals II.
Described terminal plate I is fastened by bolt passing through bolt hole A with external current－carrying conductor, and terminal plate II is worn by bolt
Cross bolt hole A to be fastened with external current－carrying conductor, current－carrying conductor is including copper bar, excitation wire, bare copper wire etc..
Described binding post I docks fastening rear enclosure with binding post II loaded on grading ring inner side, and through on grading ring
Ring-type transverse slat center, and by rectangular channel I and rectangular channel II and the inner side clamping of ring-type transverse slat.
Described bolt hole A arranges for 3 × 3 matrixes.
Described bolt hole B is 3 × 1 vertical arrangements.
The present invention is improved on the basis of the original binding post of transformer, i.e., the terminal plate I on the downside of bolt hole A
One side sets rectangular channel I, and grading ring is set in binding post outside, and grading ring can make ring-type transverse slat clamping by self gravitation
In in rectangular channel I.The binding post need to only be installed once, be firmly installed without dismounting, grading ring when installing grading ring, wiring side
Just, improve experimental safe coefficient, it is adaptable to various sleeve pipe outlet terminals for needing to install grading ring.
