1、 Product Overview:
MHJY-HIThe dielectric strength tester for insulating oil is based on national standardsGB-86 "Method for Measuring the Dielectric Strength of Insulating Oil" has been developed. The instrument's LCD display screen can display the test process and results, and the built-in EEPROM memory can store up to 100 sets of test data and results. All human-computer interaction operations are completed by rotating the mouse, and the micro printer can print the test results at any time. The tester is easy to operate, powerful in function, stable and reliable, and has strong anti-interference ability. There is no crash during the test processPhenomenon occurs.
2、 Instrument features:
1. Mixing time
Mixing time refers to the time during which the instrument controls the magnetic oscillator in the oil cup to mix the test oil.
2. Rest time
The settling time refers to the output voltage of the instrument during the experimental process0kv， The time it takes for the test oil to be placed in the oil cup and wait for the next test operation
3 Initial settling time
The initial settling time refers to the waiting time after the test operator chooses to start the testAfter the initial settling time, the instrument begins to increase pressure and begin the experiment.
3 Boost rate
During the experiment, the voltage rise rate of the output voltage
4. Breakdown test
The process of breakdown test is that the output voltage of the instrument is0 rises at a rate of 2kv/s until breakdown occurs
5 Voltage withstand test
During the withstand voltage test, the instrument should be boosted to the withstand voltage value, then the boost should be stopped and left for a period of time to check for breakdown
6 average values
The average value of several consecutive breakdown voltages during the breakdown test of the instrument
7 withstand voltage value
During the withstand voltage test, the instrument should be boosted to the withstand voltage value, then the boost should be stopped and left for a period of time to check if breakdown occurs
8 waiting time
During the withstand voltage test, the instrument rises to the withstand voltage value and stays there for a certain amount of time
