This 100kV insulation oil dielectric strength tester is a high-accuracy instrument carefully developed by all scientific research and technical personnel of our company in accordance with the relevant provisions of the national standard GB507-1986 and the industry standard DL/T846.7-2004, giving full play to their own advantages, through many field tests and long-term unremitting efforts. degree, fully digital industrial instruments. In order to meet the needs of different users, this series of instruments can be divided into single-cup, three-cup and multi-cup models. The instrument is easy to operate and beautiful in appearance. Due to the use of fully automatic digital microcomputer control, the measurement accuracy is high, the anti-interference ability is strong, and it is safe and reliable.
1. The instrument is controlled by a large-capacity microcontroller and works stably and reliably;
2. The instrument is equipped with a wide range watchdog circuit to prevent crashes;
3. Multiple operation options. The instrument program is equipped with two national standard methods GB507-1986 and GB507-2002, industry standard DL/429, international standard IEC156 and customized operations, which can adapt to the various choices of different users;
4. The instrument oil cup is cast in one step using special glass, which eliminates interference phenomena such as oil leakage;
5. The unique high-voltage side sampling design of the instrument allows the test value to directly enter the A/D converter, avoiding errors caused in the analog circuit and making the measurement results more accurate;
6. The instrument has over-current, over-voltage, short-circuit and other protection functions inside, and has strong anti-interference ability and good electromagnetic compatibility;
7. Portable structure, easy to move, easy to use indoors and outdoors.
