Total air content test in batch insulating oil；It is simple to operate, with oil circuit Quick self-cleaning and System self-test function；It is few with oil mass, often
Secondary test oil<35mL (containing rinse oil mass), the sample oil adopted back using a 100mL syringe can complete reperformance test or
Sundry item is tested, and reduces the workload of each links such as sampling, cleaning syringe；Safeguard and verification is convenient, digital display can be used
Mode shows the pressure value of each link in real time, and ocular and clear, tester working condition judges ocular and clear；By by quantitative pot 2,
Vacuum receiver 4 and oil extraction fill 5 and are both designed as stainless steel products, so, easy to carry, not cracky, the small volume of instrument, energy
It is adapted to electrical equipment to install and use at the scene when overhauling；By in the outer wrapping heat-insulation layer of vacuum receiver 4, with reduce it is extraneous because
Influence of the element to temperature measurement result；The filter 19 added can prevent dust and foreign matter in air from entering in this tester；
This method of testing is using high-precision absolute pressure e measurement technology, using dynamic differential pressure measuring method, and differential pressure measurement is accurate, so as to enter one again
Improve to step the accuracy and repeatability of test result；It is simple to operate, enter after the logical sample oil of oil sample mouthful 1, surveyed automatically by program
Examination, directly displays and preserves result, and intelligence degree is high, with oil circuit Quick self-cleaning and System self-test function.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
