Automatic testing system for transformer relay protection equipment

Abstract

The invention relates to an automatic test system for transformer relay protection equipment. The system comprises a clamp, a relay protection instrument, a switch and a host computer, the clamp is provided with a connection port which is connected to the to-be-tested equipment, the to-be-tested equipment is connected with one end of the relay protection instrument through the connection port, theother end of the relay protection instrument is connected with one end of the switch, and the other end of the switch is connected with the host computer. The host computer sends a test instruction to the relay protection instrument through the switch; the relay protection instrument determines the output analog quantity of the tested equipment according to the test instruction; and the tested equipment acts based on the output analog quantity, and feeds back the generated test data k to the relay protection instrument through the connection port, the relay protection instrument generates a corresponding test result according to the test data and feeds the test result back to the host computer through the switch, and the host computer judges the test result and generates a corresponding test report. Automatic execution of different test items can be realized, the test result is judged, and the working efficiency of the test process is improved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to an automatic test system for transformer relay protection equipment. Background technique [0002] In the power system, the relay protection equipment is used to send a warning signal to the corresponding staff in time when the power components, such as generators and lines, or the power system itself fail to endanger the safe operation of the power system, or to the controlled Circuit breakers issue a trip command to prevent these events from developing further and reduce damage to the electrical system. [0003] In order to verify the function and performance of the relay protection equipment, it is necessary to conduct multiple tests on the relay protection equipment in advance. At present, during the test process, the tester needs to manually connect the wires, set up the switch-in and switch-out environment, and apply suitable simulation to the device. Qua...

[0003] In order to verify the function and performance of the relay protection equipment, it is necessary to conduct multiple tests on the relay protection equipment in advance. At present, during the test process, the tester needs to manually connect the wires, set up the switch-in and switch-out environment, and apply suitable simulation to the device. Quantification and statistics and calculation of test data and other operations, that is, the completion of the testing process of the hardware and protection functions of the relay protection equipment is cumbersome and requires a lot of manpower and material resources, resulting in low test efficiency
