The 3KVA/50KV Power Frequency Withstand Voltage Test Device (test transformer/control box) is a test equipment designed by Yangzhou Taiyi Electric Power 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 occasions;
● Light-touch key operation, all functions can be set via keys, 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● Fully digital calibration method, abandoning outdated potentiometer adjustments, extremely convenient for on-site use, and accuracy is easy to control (this function is password protected);
● Keys directly set the transformation ratio of the test transformer (this function is password protected), allowing flexible application when connecting test devices 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 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, 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 directly identify the test result by the alarm sound;
● Pause function, in automatic control, this function allows pausing voltage rise or fall at any point, and the pause time can be flexibly controlled by the test personnel, convenient for observing the state of the test object;
● Automatic timing function. In automatic control, when the voltage automatically rises to the set value, the device automatically starts timing. When the timing time is up, the test result is displayed, and the device automatically returns to zero;
● Manual timing function, in manual control, the timer can be started manually. When the withstand voltage time is up, 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 method, 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, and when it reaches 90% of the target voltage, the rise speed further slows down;
● Combines hardware and software anti-interference technology, with stable performance and strong anti-interference capability.
Technical parameters
1. Environmental requirements for the test transformer:
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 dangerous gases;
6 Places not subject to rainwater ingress.
Note:
1. Our factory's TYSB series test transformers can achieve AC 300kV individually, with a capacity of 300kVA;
2. If users need, a 200V cascade tap can be extracted, and two or three units can be cascaded to form AC 100kV, 150kV, 200kV, 300kV high voltages. Also, according to user needs, a 5-15kV medium voltage tap can 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-purpose test transformer;
4. Our factory can also customize various special specifications of test transformers according to user requirements.
