The advantages of ultra-low frequency cable withstand voltage tester are numerous, mainly reflected in the following aspects:
1. High security
① Non destructive testing: Compared with DC withstand voltage testing, ultra-low frequency withstand voltage testing has less damage to insulation, and harmful polarized charges will not enter the dielectric, thus avoiding insulation damage caused by testing.
② Complete protection mechanism: Testers are usually equipped with multiple protection mechanisms, such as overvoltage protection, overcurrent protection, etc., to ensure the safety of the instrument and the tested equipment during the testing process.
2. Economical and practical
① Reduce the capacity of the test power supply: Due to the use of ultra-low frequency signals for testing, the required capacity of the test power supply is greatly reduced, thereby saving energy and equipment costs.
② High testing efficiency: The tester has the characteristics of fully automated testing process, simple wiring, and easy operation, greatly improving testing efficiency.
3. Wide testing scope
① Multi frequency selection: Testers typically offer multiple frequency options such as 0.1Hz, 0.05Hz, and 0.02Hz to meet the testing needs of different voltage levels and types of cables.
② High testing voltage: The tester can generate testing voltages of up to several hundred kilovolts, meeting the testing requirements of high-voltage power cables.
4. Good equivalence
Equivalent to power frequency withstand voltage test: Scientific theory and practice have proven that ultra-low frequency withstand voltage test is highly equivalent to power frequency withstand voltage test. This means that the ultra-low frequency withstand voltage tester can be used as an alternative to the power frequency withstand voltage tester to evaluate the insulation performance of cables.
5. Small size and light weight
① Easy to carry and transport: The tester has a small size and light weight, making it easy to carry and transport to outdoor or different locations for testing.
② Space saving: The tester takes up less space for storage and use, which is beneficial for conserving site resources.
6. Fully configured and powerful in functionality
① LCD Chinese character display: The tester adopts a LCD Chinese character display interface, which is clear and intuitive, making it easy for users to view test results and set test parameters.
② Automatic storage and printing: The tester can automatically store test results and print test reports, making it convenient for users to analyze and manage data.
③ Boost, buck, measurement, and protection automation: The tester can achieve automated control of boost, buck, measurement, and protection functions during the testing process, improving the accuracy and reliability of the testing.
In summary, the ultra-low frequency cable withstand voltage tester has the advantages of high safety, economic practicality, wide testing range, good equivalence, small size and light weight, as well as complete configuration and powerful functions. These advantages make the ultra-low frequency cable withstand voltage tester widely applicable in the power industry.
The ZC-524 B ultra-low frequency and high voltage generator combines modern digital frequency conversion advanced technology and adopts microcomputer control. The boosting, lowering, measurement, and protection are fully automated, and manual intervention can be performed during the automatic boosting process. Due to its full electronic design, it has a small size, light weight, large screen LCD display, clear and intuitive display, and a printer that outputs test reports. The design indicators fully comply with the standards of the power industry and are very convenient to use.
