Description

Technical Field

[0001] The utility model relates to the technical field of distribution network warehouses, in particular to an auxiliary test tool connection shell. Background Art

[0002] In modern power grid systems, in order to ensure the safe and stable operation of the power grid, a variety of relay protection devices are installed in the power grid system. When a power line or equipment fails, the abnormal situation can be quickly detected and the fault area can be automatically cut off to prevent the accident from expanding and protect other equipment from being affected. There are many types of relay protection devices in the power grid system, and the logic of each device is different.

[0003] In order to ensure that the relay protection device functions normally, it is necessary to conduct annual inspections on new relay protection devices and existing relay protection devices. During the annual inspection, the accuracy of the logic action of each protection device needs to be verified to ensure the normal operation of the relay protection device. During the accuracy verification of the logic action of the protection device, each time a port test is performed, the operator needs to insert the detection contact into the port to be tested and manually record the type or number name of the port to be tested. At the same time, only one group of ports to be tested can be tested. Taking the main transformer as an example, the main transformer protection has many tripping outlet pressure plates, nearly 20, and the inspection Every time maintenance personnel perform protection calibration, they need to face up to 200 types of tripping logic. In order to improve detection efficiency, in actual use, they choose to expand the number of detection channels to improve detection efficiency. In order to maximize the expansion of the number of channels, it is necessary to ensure that the test information can be clearly read. Therefore, a master and slave cooperation relay protection operation test tool has been developed. The matching use of the master and slave greatly improves the detection efficiency. However, in actual use, there are many tools on the operation site. During shipment, the master and slave are mixed with the on-site tools, which is chaotic during transportation. When the relay protection operation test is required, the master and slave cannot be found in time.

[0004] Therefore, an auxiliary test tool connection shell is proposed to prevent the master device from being separated from the slave device during transportation. Utility Model Content
