Technical Field
The invention relates to the technical field of application of auxiliary measurement devices for relay protection tests in the power industry, in particular to an auxiliary connection device for test connection lines of a power relay protection tester.
Background
With the development of science and technology and the progress of society, the demand for the power grid is increasing worldwide, which puts higher demands on the stability of the power grid. The maintenance work is an important link for stabilizing the power grid, and the work efficiency of the maintenance work can directly influence the final power supply efficiency. The relay protection verification test is an important detection work which must be done by a protection device before the power equipment is put into operation, and once the protection device fails, inestimable loss is brought to the power equipment. In the work of the test connecting line of the existing power relay protection tester, the four plugs of red, green, yellow and black in the connecting line of the test tester are usually respectively inserted into the corresponding terminal rows for testing the transformer substation cabinet. The jacks in the terminal row for the transformer substation screen cabinet test are generally small, and in the process of inserting the connecting line plugs of the test instruments one by one, the first plug is easy to insert, but the later operation is easy to extrude, so that the operation is time-consuming. Once the jacks are too tight or inaccurate in checking, when the jacks are inserted brute force, the terminal block of the screen cabinet of the transformer substation is damaged, even mistakenly touched, and other live equipment is mistakenly operated, so that an electric power accident is caused, and great potential safety hazards are brought to safe operation of a power grid. Therefore, a novel auxiliary connecting device for a test connecting wire of a power relay protection tester needs to be invented to change the working mode of the current test wire connection.
According to the auxiliary connecting device for the test connecting wire of the power relay protection tester, the scattered connecting plugs are switched into a row of integral plugs through the auxiliary connecting device for the test wire, and the integral plugs can be connected into a terminal row of a transformer substation cabinet at one time in use, so that the time-consuming problem of one-by-one wiring is avoided, the problem of difficult connection due to improper one-by-one connection angles is avoided, the situations of wrong wiring in the wiring process and wrong touch and misoperation of other running live equipment are avoided, the working efficiency and the working safety are improved, and the powerful guarantee is provided for efficient test regular inspection. The schematic diagram of the present invention is shown in fig. 1.

In view of the above-mentioned shortcomings of the prior art, the invention provides an auxiliary connection device for a test connection wire of a power relay protection tester, which is formed by sequentially connecting a front-end decentralized connection plug, an intermediate conversion device and a rear-end merged adapter jack.
The technical scheme of the invention is as follows: the utility model provides an experimental connecting wire auxiliary connection device of power relay protection tester which characterized in that: the front end decentralized connecting plug, the middle conversion device and the rear end merging switching jack are sequentially connected; the front end distributed connecting plug is embedded in the middle conversion device; the intermediate conversion device is reliably connected with the rear-end merging and switching jack.
Wherein, the front end decentralized connecting plug is embedded in the middle conversion device; the intermediate conversion device is reliably connected with the rear-end merging and switching jack. Meanwhile, the front-end decentralized connecting plug can realize the connecting function of the original plug of the test connecting wire of the relay protection tester. The rear-end combination switching jack can be stably and reliably connected with a test terminal row jack in a screen cabinet in a transformer substation. The middle conversion device can realize the conduction and breaking functions of the front-end scattered connecting plug and the corresponding rear-end combined switching jack.
