Thông số kỹ thuật: Thiết bị thử cao áp AC/DC HVTS-70/50

High voltage test system HVTS-70/50 is designed for testing the insulating properties of power cables and solid dielectrics with a rectified voltage of up to 70 kV, and solid dielectrics with sine-wave voltage of up to 50 kV at 50Hz frequency in accordance with GOST 1516.2.

Main advantages 

HVTS-70/50 is portable equipment. The control unit is enclosed in high-impact plastic case with a handy strap. The complete set of the cart for easy transport by one person.

The test system HVTS-70/50 is:

- Supplies the high voltage test on the object and control of leakage current;

- Ensures high accuracy and maintenance of the test voltage at a certain level, it is possible to adjust the leakage current with an external capacitor additional DC voltage during the test;

- Measures the voltage directly at the load, allowing you to have a real idea about the stress tests on the object and control it with the specified accuracy. In addition, significantly increasing the safety of the staff, especially when removing the residual capacitive charge when disconnecting the high voltage;

- Made in a sealed enclosure provides protection for remote control from dust and moisture, which is especially important when using the machine in the field;

- Equipped with a modern system of removal of residual capacitive charge using the secondary winding of the transformer and has an optional external shorting;

- A protection scheme on excess input and output current limit and set the output voltage exceeds the set. HVTS-70/50 has the ability to program required for a particular test value of the maximum current and maximum voltage protection circuitry;

- High voltage unit has a built-in pressure sensors and temperature sulfur hexafluoride transformer with output of their state on the graphic display;

- The ability to save the settings of the eight most commonly performed types of testing (insulators, surge protectors, switches, cables, 6.3 kV, 10 kV cables, etc.);

- Display all the necessary information on the specifications and test results on a graphical display. During the test, shows the numerical values of the test voltage (rms), test current (rms) and the timer duration of the test. Additionally displays the voltage (amplitude), the shape factor for AC voltage or crest factor for the rectified voltage. An estimation of the dynamics of changes in the test parameters displayed a linear scale display of voltage and current;

- A choice between manual and automatic operation. The latter involves the installation of the operator values of the test voltage in steps of 0.1 kV, lifting speed of the test voltage, the voltage test current protection operation time of the test;

- Preservation of the non-volatile memory of archival records of tests carried out with information about the time of the test, the averaged voltage at the facility and the leakage current;

- The ability to work remotely - reading the archived data on the tests carried out, the setting and the choice of test parameters, workflow management
