Nonwoven Fabric Electrostatic Electret Discharger Working Principle:
The static 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, thereby charging the object (workpiece) (artificial charging). The higher the voltage, the larger the effective range.
Product Features:
● Clear and intuitive readings of data such as voltage, current, time, status information, and prompt messages;
● Full Chinese interface, simple and clear operation, adaptable to various application scenarios;
● Touch-key operation; all functions can be set via keys, enhancing product safety and reliability;
● Fully digital calibration method, replacing outdated potentiometer adjustments, extremely convenient for on-site use, and easy to control accuracy (this function is password-protected);
● Direct key setting of the test transformer ratio (this function is password-protected), allowing flexible use when connecting testers of different voltage levels, truly enabling one control box to be compatible with multiple transformers;
● Status reminder function with full Chinese guided operation, allowing proficient operation even without a manual;
● During the test, a flashing high-voltage symbol is displayed on the screen to constantly remind operators to pay attention to safety;
● Test result display function, automatically judging the test result (pass or fail), and reliably recording the voltage during overcurrent, flashover, or breakdown of the test object;
● Audible alarm for test results; different alarm sounds are emitted for pass or fail, allowing test personnel to identify the result directly from the alarm sound;
● Pause function: in automatic control mode, this function allows pausing the voltage rise or fall at any point, with the pause duration flexibly controlled by the 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 ends, the device automatically returns to zero (only available on benchtop devices);
● Manual control mode: this mode is similar to traditional electric raise/lower methods, with rise/fall controlled by buttons; the device automatically judges 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% of the target voltage, the rise speed further slows down;
● Combines hardware and software anti-interference technologies, providing stable performance and strong anti-interference capability.
