TH2840NX Automatic Transformer Test System

TH2840X series automatic transformer test system is Changzhou Tonghui Electronics in many years of experience in transformer testing, the use of a new generation of technology to succeed in a new generation of automatic transformer test system, innovative use of dual-CPU architecture, the underlying system of Linux, 10.1-inch capacitive touch screen, Chinese and English operating interface, built-in instructions and help and other new generation of technology, to solve the previous test The system setup is cumbersome, the test speed is slow, the display is complementary, the PIN foot position is insufficient and other defects.

TH2840X series automatic transformer test system benefits from the use of a 10.1-inch, resolution up to 1280 * 800 capacitive touch screen, you can set all the feet, test conditions, feet in series and parallel, balance settings, etc., the same screen operation, to simplify the setup process, and reduces the difficulty of the instrument operator to set up.

A. Revolutionary design

Dual-CPU architecture, Linux underlying, support for touch screen, keyboard, mouse, built-in Chinese and English help and other design, bringing an unparalleled operating experience, the

Significantly reduces the barrier to entry for operators and improves testing efficiency several times over.

The following is a comparison between the classic TH2829X and the latest model.

B.10.1-inch large screen, simplify the setup efficiency, reduce the operation difficulty

10.1-inch touch screen, 1280 * 800 resolution, touch the large screen to bring more benefits is that all the transformer feet associated with the test parameters, feet in series and parallel, sorting parameters and other parameters placed on the same screen, directly with the hand or keyboard and mouse operation, not only fast operation and looks like by no means crowded and cluttered.

According to the cultivation of Tonghui Electronics in the field of transformer test for more than ten years, it has been continuously improving for the problems encountered in the test of the early automatic transformer comprehensive test system.

1. Graphical transformer foot position association page

Early automatic transformer test system foot associated with the page setup is cumbersome, and can not be the first time the transformer foot, test fixture foot one-to-one correspondence, setup difficulties

For this drawback, a new generation of automatic transformer test system in the foot associated interface increased picture, color, frame line and other elements to enhance the foot set up and test the correlation of the bullhorn, the user can be the first time the transformer foot associated with the physical object, reduce the difficulty of setting and wiring errors possible!

2. Single page setup transformer test conditions

Early automatic transformer test systems need to enter different setting pages to set test parameters, such as setting Lx parameters, need to enter 6-7 different sub-pages, quite cumbersome.

After improvement, now multiple parameters can be switched in one page, and all the related parameters of Lx can be set up in one table, which is clear at a glance and greatly improves the setting efficiency.

3. Improvement of serial and parallel setting of the foot position

When setting the footer for earlier models, you need to go to different sub-pages for serial and parallel footers.

Improved to set up the footer series and parallel connections directly in one page.

4. Improved multi-foot input method

In transformer scanning settings, it is often necessary to enter a number of consecutive foot inputs such as 1,2,3,4,5,6, so the input method has been improved to use the customary way of inputs such as 1~6 to indicate the consecutive way of inputs, which simplifies the display page and improves the efficiency of inputs.

5. Increase the average number of times and delay settings for each scanning parameter to increase stability.

In the transformer scanning test, due to some of the inductance circuit inductance is large, need to be stabilized after a certain period of time to read the accurate value, for this situation, each scanning parameter to increase the average number of times and delay settings to increase the stability, and at the same time will not affect the speed of the other parameters of the test.

6. Improve the leakage sense setting method

When testing leakage inductance Lk in multiple windings, earlier instruments needed to constantly switch between corresponding windings and set the nominal value and limit value, which was very troublesome. The new generation of automatic transformer test system improves this setup by setting the foot position and connection mode of different secondary windings directly in the same setup page, eliminating the need to input the leakage inductance pins, and inputting the nominal value, upper and lower limits directly at the corresponding pins.

7. Improved balanced scanning method

When testing the balance of multi-winding transformers, just like testing leakage inductance, earlier instruments needed to constantly switch the secondary balance foot position and set the corresponding limit value, the new generation of automatic transformer test system has improved this setting, all the balance setting items can be set up in the same page, and in response to the shortcomings of the earlier balancing points of up to 5 points, it has been upgraded to 10 points.
