How to use the VLF very low frequency withstand voltage generator
The Very Low Frequency HV Test Set is a device designed for ultra-low frequency withstand voltage test. It has a wide range of applications, including insulation test of power system, transformer test, etc. Correct use and maintenance of the device is essential to ensure the accuracy of test results and the safety of operators.
Operate Steps
1. Preparation
Before using the ultra-low frequency withstand voltage generator, first make sure that all connections are correct, especially the connection of the booster. At the same time, before use, you must ensure that the instrument has been fully discharged to prevent electric shock accidents.
2. Set test parameters
In the parameter setting interface, set parameters such as output frequency, test time and test voltage according to test requirements. Make sure that all settings meet relevant test standards.
3.Boost operation
Before boosting, confirm that the test product has been fully discharged. After starting the boost, if you need to stop the operation, you should use the stop button instead of directly turning off the power switch, and turn off the power after the test product is fully discharged again.
Safety precautions
During operation, ensure that all grounding connections are good to prevent high voltage discharge. Check the reliability of the grounding wire before use and remain vigilant throughout the test.
Maintenance and care
Regularly maintain and service the ultra-low frequency withstand voltage generator to ensure that the equipment is always in the best working condition. Check whether the fuse is intact to ensure that the power can be cut off in time in an emergency.
Operational Details
Parameter adjustment and test product connection Adjust parameters such as current, voltage and frequency according to the test requirements, select the appropriate test product, and ensure that the test product is correctly connected to the high-voltage output terminal of the equipment. Pay attention to avoid problems such as poor hook contact, poor grounding contact and excessive air humidity.
Equipment startup and monitoring After turning on the power, check whether the equipment is working properly, such as whether the digital display is on, whether the high-voltage display light is on, etc. If the equipment does not work or works abnormally, refer to the troubleshooting method for processing.
Safety measures during the test When conducting the test, ensure that the test product is fully discharged, avoid contact with exposed circuits and live metal, and do not operate in a humid environment. The operator needs to check the power supply voltage, grounding and moisture-proof measures.
Post-Test Operations
After the test, disconnect the test sample from the equipment and use a discharge rod to discharge the test sample and equipment to ensure that both the test sample and equipment are in a safe state. Afterwards, clean and maintain the equipment, including checking the appearance, dust prevention, and regularly replacing fuses and batteries.
The ultra-low frequency withstand voltage generator adopts microcomputer control, realizes full automation of boosting, reducing, measuring and protecting, and allows manual intervention in the process of automatic boosting. It is an ideal tool for high voltage withstand voltage test of electric power. During use, strictly abide by safety regulations and operating procedures, which can not only ensure the accuracy of the test, but also ensure the personal safety of operators and the integrity of equipment.
