Huazheng HZJQ-D1 70KV One Cup Transformer Oil BDV Tester With Lithium Battery

The insulation oil dielectric strength tester is a product developed by our company's research and technical personnel. It adheres to the national standard GB 507-1986 and the relevant provisions of the IEC 60156 international standard. Leveraging their expertise and after extensive field tests and continuous efforts, we have developed a high-accuracy, fully digital industrial instrument.

To meet the diverse needs of users, this series of instruments is available in single-cup, three-cup, and multiple-cup models. The instrument is easy to operate and features an attractive design. With automatic digital microcomputer control, it offers high measurement accuracy, strong anti-interference capabilities, and safety. The instrument is powered by a lithium battery, allowing tests to be conducted without an external power supply.

Instrument Characteristics

1.The instrument is controlled by a large-capacity microcontroller, which is stable and reliable.

2.A wide-range watchdog circuit is integrated into the instrument to prevent crashes.

3.The instrument offers various operational options, including two national standard methods (GB 507-1986 and GB 507-2002), the industry standard DL / 429, the international standard IEC 156, and custom operations, providing 10 optional standards to meet the needs of most countries.

4.The instrument's oil cup is cast from special glass in a single piece, eliminating the risk of oil leakage and other interferences.

5.The unique high-voltage sampling design allows the test value to enter the A/D converter directly, avoiding errors in the analog circuit and resulting in more accurate measurement results.

6.The frequency can be set according to customer requirements and can be converted to 50/60 Hz to meet different needs.

7.The instrument is equipped with overcurrent, overvoltage, and short-circuit protection functions, providing strong anti-interference capability and good electromagnetic compatibility.

8.It has a built-in lithium battery, eliminating the need for an external power supply. The portable structure makes it easy to move and convenient for both indoor and outdoor use.
