The parts such as capacitance, damping resistance, equalizing resistance, saturable reactor, thyristor control unit form.Wherein, by multiple brilliant locks
Desired system voltage can be obtained in tube elements series connection.Each direct current has a power failure, and must carry out repair and maintenance to converter valve equipment, must be right
Each thyristor grade is tested for the property, and has ensured that system normal table is run.
Currently, in HVDC transmission system, brake tube ability meter type is various, such as SIEMENSTPL687, west electricity
ZX-3 etc..These testers are to be based on being tested under laboratory condition, can only be tested every time single thyristor, and
In actual DC ice melting system, the quantity of converter valve thyristor is 132, and the spacing between thyristor is very small, using normal
Advise wiring, it has not been convenient to wiring, during the test human hand go wiring, be also unfavorable for the safety of experimenter.On the other hand, it utilizes
Above-mentioned instrument is tested, and the mode that must shift two terminated lines successively manually carries out, and the artificial wiring of light is extremely inefficient,
Time-consuming, and number of repetition is too many, and staff is also easy fatigue.
Utility model content
The purpose of this utility model is to propose a kind of simple auxiliary connection based on converter valve thyristor level ability meter
Device, to reach safe and efficient technique effect.
The utility model is achieved through the following technical solutions：
A kind of simple auxiliary connection device based on converter valve thyristor level ability meter, including it is transverse support bar, vertical
To supporting rod, contact pin, jack and vertically and horizontally fixing piece, one end of the vertical supporting bar pass through vertically and horizontally fixing piece and the institute

It is dynamic.The transverse support bar 1 and the material of vertical supporting bar 2 are insulating materials.
As shown in figure 3, in use, the anode of thyristor tester first is connected on the left side of auxiliary connection device, cathode connects
Two lines (if the sequence of thyristor is from right to left, in thyristor tester, it is suitable to be exchanged in the right side for auxiliary connection device
Sequence), wherein p-wire is flexible cord.
According to it is above-mentioned carefully connect the wire after, have experimental condition.Auxiliary connection device is first placed on V1 thyristors two by testing crew
End, then another testing crew clicks start button on thyristor tester.Test result to be measured appears in thyristor test
When on instrument, testing crew decontrols auxiliary connection device, and another service personnel records the test result of V1.
The thyristor that V2 to V13 is finally detected according to the detection method of V1, records related data.
