If the power engineering company wants to test the performance of the power transformer, if there are many projects to test, it needs to use the transformer comprehensive test bench, so how to do the transformer comprehensive test bench how to do the no-load test? This article will give you a brief introduction.
1. The output power terminal connected to the power line operator characteristics test transformer is the low voltage side of the test transformer;
2, the operator turns off the main test power switch, when the main power indicator is on, the operator opens the power lock switch;
3. The operator presses the "B" key of the remote control. At this point, the "remote control prompt" alarm on the test panel prompts the operator to be ready.
4, the operator press the "bell" button, prompting the operator to send power;
5, the operator press the "power" button on the test instrument panel, then the test instrument display friendly interface, and start the computer, control transformer testing software;
6, operators should set the parameters of the characteristics of the testing machine according to the test requirements (see the specific operation of the transformer test software manual);
7. The operator selects the current according to the test requirements and presses the corresponding current file button on the test panel. At this point, the corresponding current file indicator light is lit;
8, the operator press the "direct loop" button on the panel of the test bench, and the corresponding indicator light is on;
9, the operator presses the "function off" button on the test board table, then the corresponding indicator light;
10. When the operator presses the "three-phase off" button on the panel of the test bench, the corresponding indicator lights up and the test site alarm light flashes.
11, the operator press the "characteristic lift" button on the test panel, and move the lift when the lift indicator light is on;
12, the operator press the "characteristic boost" button on the panel of the test bench, observe the voltage test data of the transformer measurement and control software or the voltage data on the characteristic tester, so as to stop the lifting when the voltage is needed.
13, the operator to transformer test software, print out the test data;
14. The operator presses the "characteristic step-down" button on the panel of the test bench, and the step-down indicator lights up at the same time, reducing the voltage to zero, and the zero indicator lights up;
15. The operator presses the "emergency stop" button on the test panel, and the total power supply of the test power is disconnected;
16, the operator press the "function shift" button on the panel of the test bench, the selected current file exits, and the function shift indicator opens;
17. When the operator presses the "A" button on the remote control, the power supply will be disconnected from the bench test.
18. Characteristic no-load test completed.
Transformer comprehensive test bench function is more, can do a lot of tests, so power workers need to master a variety of testing methods, in order to work with ease.
