Description

A mobile relay protection experimental device

technical field

The utility model belongs to the technical field of electric power, in particular to a mobile relay protection experiment device.

Background technique

There are many kinds of relay protection experiment items, and there are also many types of secondary equipment in the substation responsible for maintenance. Therefore, before work, the secondary maintenance personnel not only need to prepare special test instruments for each experimental item, but also need to prepare experimental lines, power panels, Toolbox and experimental accessories, such as alligator clips, shorting strips, shorting wires and pins, and many other common experimental supplies. The following problems are mainly encountered in the on-site work: (1) The delay of the construction period due to the omission of experimental supplies. When working in the field of relay protection, there are many types of equipment and items to be tested. Before work, it is necessary to carefully check whether the test supplies are complete. , The test supplies are miscellaneous and numerous, it is inconvenient to carry and the test supplies are easy to miss, which causes work delays and reduces work efficiency. (2) For the secondary splicing of the experimental lines, the length of the required test lines varies according to different test items. When the test project requires a long test line, we often splice the existing test lines. There are two main ways to splice the test lines: one is to use the transition post to splice the test lines. After the splicing is completed, safety measures need to be taken at the transition. This method increases the number of test articles required to be carried on site, and the work efficiency is low. Second, when the on-site test supplies are insufficiently prepared and there is a lack of transition posts, the test lines to be spliced are often directly plugged together with banana heads on site, and safety measures are taken at the exposed plugs. This method also needs to pay attention to the safety of the spliced test lines. Phase separation problems, low efficiency, and potential safety hazards when splicing is unreliable. (3) The power cord of the power supply panel is manually unwound and taken up, and all kinds of relay protection test instruments are connected to 220 volts AC power supply. In the field, it is often necessary to use the power panel to lead the AC power from the maintenance power box for the tester to use. The process of unwinding and retrieving wires on the power supply panel requires two people to cooperate, which is time-consuming and laborious, wastes manpower, and reduces work efficiency.
