Abstract
The utility model relates to an operation rod for a quick test of thyristors. Male threads of a holding rod are connected with female threads of a middle rod. Male threads of the middle rod are connected with female threads of a main rod. The female threads of the main rod are connected with male threads of a contact head. The main rod is provided with a nylon self-adhering bandage. Two sides of the contact head are provided with two lead connecting sockets. One end of the contact head can be connected with thin copper posts on two sides respectively through fixing lines while the other end of the contact head can receive testing a connection wire. By using the operation rod for the quick test of the thyristors, damages caused by direct contact of the test lead and an optical cable are eliminated, the operation flexibility can be improved and personal injuries and device damages caused by that an operator gets in and out of a valve body frequency are reduced.
Description
[technical field]
The utility model relates to the electric power overhaul equipment technical field, specifically, is the quick test operation bar of a kind of thyristor.
[background technology]
In the maintenance of DC converter station, the test of the triggering and conducting of thyristor and BOD is to guarantee one of key project of the AC and DC change of current in the change of current valve body.Owing to have thousands of thyristors to test one by one in the one pole converter valve, therefore, the time of consumption is long, manually bigger.The test present situation is as follows:
When (1) testing, testing crew ploughs under from overhead vehicle and has connect line the valve body, gets back to and carries out pressure build-up test (annotating: because in the valve body precision elements such as optical cable, TE plate are arranged, so entering valve body can not use of seat belts) in the overhead vehicle then.
(2) the sagging and optical cable close contact of test lead damages optical cable easily.
(3) overhead vehicle and valve body grading shield are near excessively, because the trial voltage height, human body is touched induced electricity easily.
(4) because influenced by short-circuit current, the long-time test unit that uses is overheated easily, causes the ordinary tripping operation of power supply, causes the fault of test unit.
Therefore, carry out above-mentioned two tests and the time not only require a great deal of time and manpower, and jeopardize the person and device security.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of thyristor quick test operation bar.
The purpose of this utility model is achieved through the following technical solutions:
The quick test operation bar of a kind of thyristor, it comprises hand-held pole, king-rod, mobile jib, contact head is characterized in that, the external thread of hand-held pole is connected with the internal thread of king-rod, and the external thread of king-rod is connected with the internal thread of mobile jib, and the internal thread of mobile jib is connected with the external thread of contact head.
The nylon self-adhering fascia is set on the described mobile jib, and the nylon self-adhering fascia is fixed on the mobile jib by screw.
Described contact head is the concave shape contact head, and its bottom is 14-18cm for the insulating material width, and the center is porose.
The both sides of described contact head are provided with two leads and connect socket, and each is communicated with the thin copper post in both sides an end by static line, and the other end can insert test connection.
Being shaped as of described copper post is cylindrical, a kind of in taper or the aciculiform.
Compared with prior art, good effect of the present utility model is:
(1) application of the present utility model, (annotate: former the taking time of above-mentioned two pilot projects of thyristor finished one in about 3 minutes, then needed to finish in about 1 minute and 30 seconds with the method can to shorten test period; Manually can be down to 6 people in shifts by original 9 people gets final product).
(2) the utility model has stopped that test lead directly contacts with optical cable and the situation that may cause optical cable to damage.
(3) the utility model can improve flexibility of operation, has reduced operating personnel when frequently passing in and out valve body, the damage of personal injury and original paper.
(4) in limited test period, for test unit has won time of abundant heat radiation, reduced the number of times of device and power fail.

[embodiment]
The embodiment of the quick test operation bar of a kind of thyristor of the utility model below is provided.
See also accompanying drawing 1,2,3,4,5a, 5b, 5c, 6, the quick test operation bar of a kind of thyristor, it comprises hand-held pole, king-rod, mobile jib, contact head is characterized in that, the external thread of hand-held pole is connected with the internal thread of king-rod, the external thread of king-rod is connected with the internal thread of mobile jib, and the internal thread of mobile jib is connected with the external thread of contact head.
One end of described hand-held pole is provided with external thread.
Described king-rod one end is provided with internal thread, and an other end is provided with external thread.
The two ends of described mobile jib are provided with internal thread.
The first end of described contact is provided with external thread.
The nylon self-adhering fascia is set on the described mobile jib, and the nylon self-adhering fascia is fixed on the mobile jib by screw.
Described contact head is the concave shape contact head, and its bottom is 14-18cm for the insulating material width, and the center is porose, and it is fixing to utilize the punching screw rod to dock with mobile jib, and both sides are left 2-3 aperture respectively, but in order to make concave shape both sides thin copper post spacing.
The both sides of described contact head are provided with two leads and connect socket, and each is communicated with the thin copper post in both sides an end by static line, and the other end can insert test connection.
