5KVA/50KV High Voltage Test Transformer
Darui Electric recommends:
YHGPY-10KVA/100KV Power Frequency Withstand Voltage Test Device (Test Transformer/Control Box) is a test equipment designed by Shanghai Donghai Electric according to national industry test standards. It is safe, reliable, powerful, easy to use, and simple to maintain. It is mainly used for insulation strength tests at specified voltages on various electrical products, electrical components, insulating materials, etc., to assess the insulation level of products, discover insulation defects of tested objects, and measure overvoltage capability. It is the preferred product for power operation related departments, electrical appliance manufacturing enterprises, metallurgy, coal mines, electrified railway related departments, scientific research institutions, and universities that need withstand voltage test equipment.
Product Features:
● Voltage, current, time, status information, and prompt information data readings are clear and intuitive;
● Full Chinese interface, simple and clear operation, adaptable to various application occasions;
● Touch button operation, all functions can be set via buttons, improving product safety and reliability;
● Fully digital calibration method, abandoning outdated potentiometer adjustment, extremely convenient for on-site use, and easy to control accuracy (this function is password protected);
● Direct button setting of test transformer ratio (this function is password protected), flexible and convenient when connecting testers of different voltage levels, truly achieving one control box compatible with multiple transformers;
● Status reminder function, full Chinese guided operation, can be skillfully operated even without the manual;
● During the test, a flashing high voltage symbol is displayed on the screen, constantly reminding operators to pay attention to safety;
● Test result display function, can automatically judge test results (test passed or failed), and reliably record the voltage during overcurrent, flashover, or breakdown of the test object;
● Test result audible alarm function, when the test passes or fails, the device emits different alarm sounds, allowing test personnel to identify the test result directly from the alarm sound;
● Pause function, in automatic control mode, this function allows pausing voltage rise or fall at any point, and the pause time can be flexibly controlled by test personnel for convenient observation of the test object's status;
● Automatic timing function. In automatic control mode, when the voltage automatically rises to the set value, the device automatically starts timing. When the timing ends, the test result is displayed, and the device automatically returns to zero;
● Manual timing function, in manual control mode, the timer can be started manually. When the withstand voltage time is reached, the device automatically returns to zero (only desktop devices have this function);
● Manual control mode, similar to traditional electric raise/lower voltage method, with rise/fall controlled by buttons, the device automatically judges upper/lower limits, and has overvoltage protection;
● Intelligent voltage rise speed control, when the voltage reaches 80% of the target voltage, the rise speed automatically slows down, and when it reaches 90% of the target voltage, the rise speed further slows down;
● Combines hardware and software anti-interference technologies, with stable performance and strong anti-interference capability.
