Non-woven Fabric Electrostatic Electret Discharger Working Principle:
The electrostatic generator consists of an electrostatic emitter (bar) and a DC high-voltage power supply. The DC high-voltage power supply provides negative (or positive) high voltage to the electrostatic emitter (bar), causing it to emit negative (or positive) charges, which then charge the object (workpiece) (artificial charging). The higher the voltage, the larger the effective range.
Product Features:
● Data such as voltage, current, time, status information, and prompt information are clearly and intuitively displayed;
● Full Chinese interface, simple and clear operation, adaptable to various application scenarios;
● Touch-key operation, all functions can be set via keys, improving product safety and reliability;
● Fully digital calibration method, replacing outdated potentiometer adjustment, extremely convenient for field use, with easy-to-control accuracy (this function is password-protected);
● Direct key setting of the test transformer ratio (this function is password-protected), allowing flexible application when connecting testers of different voltage levels, truly enabling one control box to be compatible with multiple transformers;
● Status reminder function, full Chinese guided operation, allowing proficient operation even without a 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, automatically judging test results (test passed or failed), and reliably recording the voltage at overcurrent, flashover, or breakdown of the test object;
● Audible alarm for test results, with different alarm sounds for test pass or failure, allowing test personnel to identify results directly from the alarm sound;
● Pause function, in automatic control mode, allows pausing voltage increase or decrease at any point, with pause time flexibly controlled by the test personnel for convenient observation of the test object 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 ends, the device automatically returns to zero (only available on desktop devices);
● Manual control mode, similar to traditional electric raise/lower methods, with raise/lower controlled by buttons. The device automatically determines upper/lower limits and has overvoltage protection;
● Intelligent control of voltage rise speed. When the voltage reaches 80% of the target voltage, the rise speed automatically slows down; when it reaches 90%, the speed further slows down;
● Combines hardware and software anti-interference technologies, with stable performance and strong anti-interference capability.
