Product Description

 

 

 

 

 

1. Product Introduce

---------------------------------------------------------

KDYD-GY power frequency overvoltage protection test device is a test device designed according to the national industrial test standard GB/T15576-2020 Low voltage complete reactive power compensation device. After the capacitor is powered off in the factory test of JP cabinet, the time for discharging from the rated voltage peak to 50V is not more than 3min. KDYD-GY power frequency over-voltage protection test device is characterized by safety, reliability, easy use and simple maintenance. It is mainly used to carry out over-voltage test under specified voltage for various electrical products, electrical components, insulating materials, etc., to measure the ability of over-voltage. It is a department related to power operation, electrical and electrical manufacturing enterprises, metallurgy, coal mines, and electrified railway departments Scientific research institutions and colleges and universities are the first choice for over-voltage test equipment.

 

2. Product features

--------------------------------------------------------
1. Voltage, current, time, status information, body type information and other data are displayed on the industrial touch screen, with clear and intuitive readings;
2. All Chinese interface, simple and clear operation, can adapt to a variety of applications;
3. The output voltage can be directly set through the touch screen button, and the test can be automatically completed by one key startup;
4. During the test, there is obvious voltage display on the screen to remind the operator to pay attention to safety at all times;
5. Automatic timing function: during automatic control, when the voltage automatically rises to the set value, the equipment automatically starts timing; when the timing time is up, the equipment automatically returns to zero;
6. Manual control mode, which is similar to the traditional electric lifting/lowering mode. The lifting/lowering is controlled by the touch button, and the equipment automatically judges the upper/lower limit, with overvoltage protection;
7. The boost speed is intelligently controlled. When the voltage reaches 80% of the target voltage, the boost speed will automatically slow down. When the target voltage reaches 90%, the boost speed will further slow down;

 

3. System characteristics

---------------------------------------------------------
 1. Automatic control function: voltage and timing time can be preset. After clicking Start, the system will automatically boost, time, reduce voltage and open according to the program set by the user.
2. Program control function: based on the automatic control function, the operator can set the test program according to the needs of the test item, and the system will automatically control and complete the test according to the setting.
3 Safety function: It has the function of software and hardware comparison and protection. The system protection value and single protection value can be set in the software, and the maximum protection value can also be preset in the hardware. The system will automatically trip if it exceeds the system or the maximum protection value. The software and hardware emergency button is set, which can be pressed in case of emergency, and the system will trip immediately to cut off the test power supply.
