Wind turbine generator tower base control cabinet detection and test device

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] Reference attached figure 1 , A wind turbine tower base control cabinet inspection device, which includes an electric control cabinet 2 and a console 1, the console 1 is provided with a start button 1-3, an upper computer 1-1, a printer 1-2, and a stop button 1-4. The electric control cabinet 2 is equipped with phase sequence detector 2-2, signal isolator 2-3, fault reset 2-4, programmable controller 2-1, action relay 2-8, fault indication 2-7, AC/DC power supply 2-5, power supply indication 2-6, the input and output ends of the tower base control cabinet 3 to be tested are connected to the electric control cabinet 2, the upper computer 1-1 and the programmable controller 2-1 is equipped with a product inspection program that matches the tower base control cabinet 3 to be tested, and the test command of the upper computer 1-1 is input to the programmable controller 2-1 in the electric control cabinet 2, programmable control The device 2-1 controls the phase sequence detector 2-2, the signal isolator 2-3 and the action relay 2-8 according to the received command to detect the connection and function of the components of the tower base control cabinet 3 to be tested, the upper computer 1 -1 shows the test result, and the AC/DC power supply 2-2 provides power for the test device.

[0014] During the test, the power indicator 2-6 lights up, the programmable controller 2-1 is powered through the AC/DC power supply 2-5, the tested product model is selected through the host computer 1-1, and the system start button 1- 3. The programmable controller 2-1 accepts instructions from the host computer 1-1, and the programmable controller 2-1 analyzes and controls the phase sequence detector 2-2, the signal isolator 2-3, and the action relay 2-8. Check the connection and function of the components of the tower base control cabinet 3. When a fault is detected, the fault indication 2-7 will light up. After the fault is removed, press the fault reset 2-4 and then proceed to the next test. The detection status is displayed All are displayed on the host computer 1-1 in real time. The test results of the tower base control cabinet 3 to be tested will be automatically stored in the host computer 1-1 database for backup and recording to ensure that the test results of the product can be traced. Printer 1 -2 Output the test results. After the product test is completed, press the stop button 1-4 to turn off the power supply and the product test ends.
