Description

Technical Field

[0001] The invention relates to the technical field of high-voltage reactive power compensation device testing, and in particular discloses a high-voltage reactive power compensation device calibration test terminal. Background Art

[0002] High-voltage reactive power compensation device is a device used to improve power factor and voltage stability in power systems. In modern power systems, the application of high-voltage reactive power compensation devices has gradually become widespread. In order to ensure the normal operation of the high-voltage reactive power compensation device, the performance of the high-voltage reactive power compensation device needs to be evaluated and tested before operation. The high-voltage reactive power compensation device is mainly composed of four cabinets, namely: incoming line cabinet, power cabinet No. 1, power cabinet No. 2 and control cabinet. Among them, power cabinet No. 1 and power cabinet No. 2 are the core power unit cabinets of the high-voltage reactive power compensation device. Each power cabinet is equipped with three groups of power units, and each group of power units is loaded with 10-16 capacitors. Under normal circumstances, the capacitors carried in each group of power units are arranged symmetrically, that is, arranged in two layers.

[0003] The invention with application announcement number: CN116754883A discloses a multifunctional detection device and detection method for a reactive compensation device. The above-mentioned prior art connects the reactive compensation device to the power grid and uses the simulated load unit set inside to measure the performance detection data of the reactive compensation device, thereby judging whether the capacitors carried by it meet the requirements of the power grid. At present, in the testing operation of high-voltage reactive compensation devices, it is necessary to connect the high-voltage reactive compensation device to the power grid in advance, and test the capacitance of each group of power units under the premise that the high-voltage reactive compensation device is powered on; the operator needs to hold a voltmeter to perform voltage tests on each capacitor in turn. If there is a defect in the power unit, the voltage test value of the capacitor will have a large deviation from the standard value, so the defective power unit needs to be repaired or replaced to ensure the normal operation of the high-voltage reactive compensation device.

[0004] It can be seen from the above-mentioned prior art that, during the verification and testing operation of the high-voltage reactive compensation device, the power workers need to have close contact with the high-voltage reactive compensation device. If a defective capacitor is found, the power workers need to manually remove the capacitor, which poses a high safety hazard. In addition, due to the large number of capacitors in the power unit and the low efficiency of manual testing, the verification and testing operation of the operators takes a long time, which makes it difficult to meet the requirements of modern production enterprises for rapid product turnover.

[0042] The working principle of the present invention is:

[0043] After the power group operator opens the door of the No. 1 power cabinet of the high-voltage reactive compensation device and the cover of the power unit, the high-voltage reactive compensation device is connected to the power grid, and the terminal device is pushed to the front of the No. 1 power cabinet. The power operator can control the start and stop of the terminal device through the master switch 22; after the terminal device is started, the cylinder 18 can push the cross plate 6 to adjust the height position along the first Z-axis guide rail 15 in the Z-axis direction, so that the test head 12 is opposite to the capacitor of this layer one by one, and under the driving action of the first motor 30, the Y-axis screw 28 and the connecting seat 31 push the Y-axis guide plate 5, so that the sliding sleeve 21 slides along the Y-axis horizontal column 4, and the electric control telescopic rod 11 can make the test head 12 close to the capacitor, so as to obtain the real-time voltage value of each capacitor of this layer, and feed it back to the data terminal in real time through the terminal socket 10, so that the specific test parameters of each capacitor are displayed on the display 54. If the test parameters of each capacitor are within the normal value range, the warning light group 56 displays a green warning light color. By controlling the first motor 30, the test head 12 is moved away from the layer of capacitors, and the third motor 47 can be used to control the second Z-axis guide plate 9 to adjust the height position in the Z-axis direction along the second Z-axis guide rail 44, so that the test head 12 can test each capacitor in the lower layer; if there are no defects in the capacitors in this group of power units, the second motor 38 can be used to control the X-axis guide plate 7 to adjust the lateral position in the X-axis direction along the X-axis guide rail 32, so as to test the capacitors in the other two groups of power units.

[0044] When the test head 12 detects that there is a defect in the capacitor, the electrically controlled telescopic rod 11 carried by the test head 12 will shrink, and the sleeve 13 will be aligned with the layer of capacitors through the third motor 47. The first motor 30 will be controlled to allow the layer of capacitors to enter each sleeve 13. After the capacitor enters the sleeve 13, the end of the capacitor will enter the rubber sleeve 14. Under the pressure of the capacitor, the end face of the inner port of the rubber sleeve 14 will contact the inner groove surface of the slot 53, and squeeze the air in the rubber sleeve 14 to the outside, so that the inner wall of the rubber sleeve 14 is tightly fitted with the outer wall of the capacitor, until the end of the capacitor touches the inner groove surface of the slot 53, and the rubber sleeve 14 will tightly absorb the capacitor in the sleeve 13. By manually pulling the stand, the capacitor can be taken out of the power unit, and the operator can further analyze its defects, so as to formulate a maintenance machine replacement plan to ensure the normal operation of the high-voltage reactive power compensation device.
