The 3KVA/50KV Power Frequency Withstand Voltage Test Device (Test Transformer/Control Box) is a test equipment designed by Yangzhou Taiyi Electric Equipment Co., Ltd. according to the latest national industry test standards. It is safe, reliable, powerful, easy to use, and simple to maintain. It is mainly used for insulation strength tests under specified voltages on various electrical products, electrical components, insulating materials, etc., to assess the insulation level of products, discover insulation defects of test 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 aliases
Test transformer, power frequency withstand voltage test device, AC withstand voltage test device, power frequency withstand voltage tester, power frequency withstand voltage instrument, power frequency withstand voltage machine. 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 scenarios;
● Touch button operation, all functions can be set via buttons, improving product safety and reliability;
● Fully digital calibration method, abandoning outdated potentiometer adjustments, extremely convenient for on-site use, and accuracy is easy to control (this function is password protected);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 to remind operators to pay attention to safety at all times;
● 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, and test personnel can directly identify the test result by the alarm sound;
● Pause function, in automatic control mode, this function can pause voltage rise or fall at any point, and the pause time can be 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 desktop devices have this function);
● Manual control mode, this mode is similar to traditional electric raise/lower voltage methods, with rise/fall controlled by buttons, and the device automatically judges upper/lower limits with overvoltage protection;
● Intelligent control of voltage rise speed. 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.
Technical Parameters
1. Environmental requirements for test transformer use:
1 Input voltage: AC 220V or 380V, 50Hz;
2 Ambient temperature: -40℃～40℃;
3 Relative humidity: ≤85% (when ambient temperature is 25℃);
4 Environment free from chemical gases and vapors;
5 No explosive hazardous gases;
6 Places not subject to rainwater intrusion.
Note:
1. Our factory's TYSB series test transformers can achieve AC 300kV, capacity 300kVA as a single unit;
2. If users need, a 200V cascade tap can be extracted to cascade two or three units into AC 100kV, 150kV, 200kV, 300kV high voltage. According to user needs, a 5-15kV medium voltage tap can also be extracted from the high voltage winding for AC withstand voltage testing of high voltage motors;
3. The "DC high voltage output" column in the table is the DC high voltage output value of the AC/DC dual-use test transformer;
4. Our factory can also customize various special specifications of test transformers according to user requirements.
