Ⅵ. Touch screen control system, computer system and software package

Touch screen control system is the latest developed by our company, with powerful function, simple operation  and  intuitive  display.  The  instrument  adopts  touch  screen  control  and  completes  the  power frequency voltage breakdown and power frequency withstand voltage test of insulating medium through human-computer conversion.

Simple parameter can be set through the touch screen to complete all tests and the test result can be exported via USB, but there will be no curve of the test process. If you need a graph, you need to connect a computer.

Test processing interface

1. During the test, the test curve can be drawn dynamically. The test curve can be superimposed and compared with a variety of colors and locally enlarged. Any section of the curve can be analyzed by regional amplification;

2 、The test data can be edited and modified, which is flexible and applicable;

3 、Test conditions and test results data can be stored automatically;

4 、The test report format is flexible and adaptable to the different needs of different users;

5 、The validity of curve data in a group of tests can be manually selected;

6 、Test result data can be imported into Excel and Word for editing;

7 、 The over-current protection device has sufficient sensitivity to ensure that the power supply is cut off within 0. 1s when sample breaks down;

8 、Durability of instrument operation: the instrument can be operated continuously without regular shutdown to protect the instrument;

9 、Automatic voltage stabilization function during voltage withstand test (not affected by voltage grid voltage fluctuation).

Ⅶ. Safety instructions for high voltage breakdown equipment:

1 Separate protective ground wire should be installed for the equipment. The protective grounding wire is mainly used to reduce the strong electromagnetic interference to the surrounding when the sample breaks down；It can also prevent the computer from getting out of control.

2、DC test discharge alarm function：After the equipment has completed the DC test, the equipment will automatically alarm when the test door is opened, and the alarm will automatically cancel after the discharge device is used to discharge.（Note: It is dangerous not to discharge after DC test, the electrode cannot be taken directly. The alarm device will remind the operator to discharge so as not to cause personal injury).

3、The test discharge device, integrated with the host, improve the function of previously equipped with a separate discharge pole.

4 、Safety protection:

①Door interlock protection

②Over-voltage and over-current protection

③High voltage warning light

④Emergency stop button

⑤Discharge alarm

⑥Leakage protection switch
