Insulating oil dielectric strength tester
Insulating oil dielectric strength tester is in accordance with the International Electrotechnical Commission standard IEC-156 international and national standard GB507-86 "insulating oil dielectric strength test" requirements, give full consideration to the needs of users at home and abroad and developed a new generation of automatic test oil cooler, a microcontroller-driven, using the first set after power-on test methods, the whole process runs automatically by computer control, easy to operate. Operations are divided into six automatic and fully automatic single operation, with automatic step-up test, automatic stirring, automatic processing, automatic printing and digital display and locking technology and other functions, intuitive readings, accurate measurement, the testing process safe and reliable.
Insulating oil dielectric strength tester adds calendar and experimental data can be stored for a long features that will change LCD digital display. Controller uses single chip microcomputer whole process of testing, anti-jamming performance is particularly strong, completely overcome the current LCD Automatic Test vulnerable high-voltage breakdown interference ills. Not only improve work efficiency, so monotonous, repetitive or boring work becomes quite mean, and safe, reliable, and accurate measurement.
The instrument is simple: Except for the first time must be preset according to the data you need outside (if measured according to GB This step can be saved, because the factory preset data by GB. 6 times, stirring for 1 minute , standing time of 5 minutes) after the key value can be measured only by. Run the diversity of ways for users to different needs and design.
Insulating oil dielectric strength testerKey Features
Insulating oil dielectric strength tester with automatic detection function, automatically execute the regulator into the reset state back to zero; according to user needs can change the number of tests, stirring standing time, voice-activated light control remind continuous printing and non-printing; the instrument magnon using automatic mixing, eliminating oil sample inhomogeneity and bubbles; using a miniature TPU-A panel printer, automatic printout.
Insulating oil dielectric strength tester Fundamentals
With the central processor, the LSI and other advanced technical components automated test equipment, fully automated operation, and through mini-printer configuration panel test oil test data, the device and general instrumentation and test compared with the same type of instrument stability good, high precision, and has good maneuverability, oil-free operation of the device in the test run in a variety of test methods, the main features:
1 automatic pilot mode: six consecutive tests, automatic averaging, through the panel printer to print out six times and the average number of test data.
2 single automatic test mode: auto-complete a trial, and print out a single test data.
AC reversible motor at 3 kV / sec uniform driven by the step-up transformer step-up regulator, when a sample is the breakdown, the protection system will automatically cut off the power supply circuit boost while protecting circuit provides an interrupt signal to the system, After the implementation of the system response test oil breakdown process, its main operation content:
1 four digital tube display flashes eight times in a row, suggesting that test oil breakdown;
2 Record the test data;
3 programmable automatically return to zero operation. Back to zero, according to the number of tests to identify whether a test operation before the next cycle or automatically exit the test status.
Insulating oil dielectric strength testerTechnical Requirements
1 Usage and Features
Stir to automatic magnetic stirring, to eliminate the presence of artificial mixing of insecurity; run times can be changed at any time, stirring and standing time; oil sample breakdown after hearing the sound alert sound and sound arrangements have a certain regularity, by listening but also to know to run a few times, if necessary audio prompts can be turned off; regulating system with variable speed mode, boost slow, back to zero fast; run diversification; calendar display time; measurement data long-term preservation. Suitable for testing various insulating oil dielectric strength of its main characteristics: features auto-detection function, such as boot automatically reset back to zero execution regulator.Using a micro-TPU-A panel printer, automatic printout. According to user needs can change the number of tests, stirring, standing time, voice-activated light control remind continuous print and non-print. The instrument uses automatic magnon stirring, eliminating oil sample inhomogeneity and bubbles.(2) technical parameters

Insulating oil dielectric strength tester maintenance
1. Equipment maintenance, care and adjustments should be professionals.
(2) The instrument can be used indoor and outdoor, but should avoid rain, corrosive gas, dust too thick, heat or direct sunlight and other places use.
3 oil cup should be kept clean, and then disable the drying period should be filled with qualified insulating oil, keeping the oil cup is not damp.
4 electrodes and then used continuously for up to a month later, a check should be carried out to test whether the change in the electrode gap with a magnifying glass electrode surface without dark phenomenon, if this phenomenon is applied silk cloth to wipe the electrode surface, and re-adjust electrode gap, to meet your requirements.Replacement Printer Ribbon
Printer ribbon cartridge and then installed in the factory is good, but after a period of use, the need to replace the ribbon cartridge, follow these steps:
1) Open the printer's front cover.
2) Gently remove the old head printer ribbon cartridge.
3) Replace the ribbon cartridge, first gently on the right end of the cartridge nose gear on the right side, left side slightly raised not to lay down, hold your finger on the ribbon cassette knob slightly in the direction of the arrow Turn it, then put down the left side of the ribbon cassette
4) mounted on the front cover of the printer can be.Replace the printer paper roll
Printer has been installed at the factory rolls, after use will need to install a new roll. General process is as follows:
1) Remove the printer front cover.
2) Remove the paper roll from the printer.
3) In the first set of the new paper roll roll axis, the paper roll into the printer according to the guide groove.
4) cut a V-shaped front end of the paper, the printer into the print head of state when the paper by hand into the mouth nose following paper, the paper goes into the nose until it is exposed from the nose in front of a certain length so far.Oil cup cleaning method
A) repeatedly wipe with a clean silk electrode surface and the electrode rod.
2) with a standard gauge adjust electrode gap.
3) with petroleum ether or ethanol wash 3-4 times, then dry with a hair dryer in the wash oil sample into the test 2-3 times.Stir cleaning method
A) repeatedly wipe with a clean silk stirring, until the surface no small particles, avoid hand contact with stirring surfaces.
2) forceps stirring, washed repeatedly immersed in ethanol, and then dried with a hair dryer.
3) forceps stirring, washed repeatedly immersed in the oil sample can be measured.
