I. Overview

There are a large number of electrical equipment in the power system, factories, mines, and enterprises, and their internal insulation is oil filled insulation. The dielectric strength test of insulating oil is a mandatory routine test.Insulation oil dielectric strength testerAdopting single-chip microcomputer control, the electromechanical integration is fully automated, with high measurement accuracy, greatly improving work efficiency and greatly reducing the labor intensity of workers.

2、 Function Introduction

1Single oil cup structure. Using microcontroller control, it can automatically complete a series of operations such as boosting, holding, lowering, stirring, static discharge, display calculation, printing, etc0-80kVConduct insulation oil withstand voltage test within the scope. And it can measure the temperature and humidity at that time.

2、adopt800×480A large screen color touch screen LCD display with an internal backlight system that can be clearly seen even at night. Operators can set the following test parameters as needed: static discharge time, boost interval, stop voltage, test frequency, and mixing switch. Equipped with a thermal printer, the printing effect is good and the noise is low.

3、Insulation oil dielectric strength testerEasy to operate, the operator only needs to input simple instructions according to the instructions, and the instrument will automatically complete the withstand voltage test according to the set parameters. The breakdown voltage value and the number of cycles are automatically stored. After the experiment is completed, the printer can be turned on to print out the breakdown voltage value and average value of each oil cup.

4、This instrument has strong adaptability and can be used in laboratories and outdoor fields. The instrument also has strong anti-interference ability and can work normally in strong electromagnetic field environments.

5、This instrument is equipped with overvoltage, overcurrent, limit and other protective devices, which absolutely guarantee the safety of the instrument itself and operators in normal use environments.

fiveCleaning method for oil cup

1、Wipe the electrode surface and electrode rod repeatedly with a clean silk cloth.

2、Adjust the electrode spacing using standard specifications.

3、Clean with petroleum ether (avoid using other organic solvents)3Secondly, each time, the following method must be followed:;

3.1 Pour petroleum ether into the oil cup and take up the space in the cup1/4～1/3.

3.2 Cover the cup mouth with a piece of glass washed with petroleum ether and shake it evenly1Minutes, pay attention to having a certain amount of strength.

3.3 Pour out the petroleum ether and dry it with a hair dryer2～3minute.

4、Clean with the oil sample to be tested1～3Next time.

4.1 Pour the oil sample to be tested into the oil cup, taking up the space in the cup1/4～1/3.

4.2 Cover the mouth of the cup with a dried glass piece and shake it evenly1～2Minutes, pay attention to having a certain amount of strength.

4.3 After pouring out the remaining oil sample, the pressure test can be conducted.

sixCleaning method for agitator

1、Wipe the mixer repeatedly with a clean silk cloth until there are no small particles on the surface. Do not touch the surface of the mixer with your hands.

2、Clamp the stirrer with tweezers and immerse it in petroleum ether for repeated rinsing.

3、Use tweezers to hold the stirrer and blow dry it with a hair dryer.

4、Use tweezers to clamp the stirrer and immerse it in oil for repeated rinsing.
