Page 9: 6、 Function Description
Figure 2 6、 Function description After connecting the gas circuit, you can open the valve on the gas cylinder, turn on the power supply of the instrument, and enter the main interface after system initialization, as shown in Figure 3, which has the functions of "... - Page 10 the equivalent pressure value at 20 ℃. The equivalent pressure value at 20 ℃ is the locking recovery value of the SF6 density relay. Verification of alarm reply value:Continue to slowly inflate the SF6 density relay at a certain speed. When the alarm relay of the density relay acts, record the pressure value under the current ambient temperature, and convert it into the equivalent pressure value at 20 ℃.
- Page 11 Figure 4 This is the parameter setting interface of SF6 density relay verification.In this interface, four parameters can be set, such as upper limit pressure, detection times, temperature acquisition, signal type, etc. "Upper limit pressure" refers to the switching pressure value from air inlet to air outlet when testing the density relay.
- Page 12 Single block:When single locking is selected, the system has two test signals connected to the instrument, among which there must be a single alarm, and either single locking 1 or single locking 2 can be selected. At this time, the system tests two signals at the same time.
- Page 13 displayed on the screen. At the same time, the status bar at the lower left corner of the screen will prompt the detection times. The schematic diagram of pressure increase and pressure decrease is shown in Figure 6 and Figure 7: Figure 6 Figure 7 At this time, click "stop"...
- Page 14 Figure 8 Figure 8 shows the test results of three times, "signal type" is double locking. Click "start" to clear the displayed value and detect again. Click "save" and "print" to save and print the test results.Click "return" to return to the density relay parameter setting interface.
- Page 15 test point, which can be set up to four groups at most. When setting, it should be set from small to large in order. If there is a mistake in setting, click "OK" and the following prompt will appear, as shown in Figure 10: Figure 10 After setting the pressure target value correctly, click "OK"...
- Page 16 of the pressure gauge to be tested, "confirm" refers to the completion of a group of test points, calculation and display of the error value, which can be saved and printed after the completion of the test. Click "start" to start detection. When the current value Pt in the first column will rise to the preset value of the first set of test points 0.200mpa, it will stop as shown in Figure 12.
- Page 17 Figure 14 Click "start" to start the second test. The operation process is the same as the first test. The result after the completion of the three preset tests is shown in Figure 15. Figure 15 At this time, you can click "save" and "print" test records, and click "return" to return to the test interface.
- Page 18 interface is 20 degree pressure gauge calibration. The test interface shows that the test result is different from that of normal temperature pressure gauge. The equivalent pressure value at 20 ℃ is also displayed on the current value item, as shown in Figure 16. Figure 16 3.
- Page 19 Figure 18 Rotate left and right to select the number of groups, and then "click to select" to enter figure 19. Figure 19 In this interface, you can select to view, delete and print historical data by turning the mouse left and right. Click "▲▼" to return to figure 18, click "return" to return to figure 17, and click "view"...
- Page 20 This interface is for detailed historical measurement data. Click "print" to print the current historical data, and click "return" to return to figure 18. In Figure 17, you can select to view the calibration record of normal temperature pressure gauge and 20 readings of pressure gauge. The interface and operation process are the same as the calibration history of density relay.
