Temperature rise frequency conversion loss measurement device

Temperature rise frequency conversion loss measurement devicePerformance Characteristics

1. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and a dedicated testing line are needed to achieve oil dielectric loss measurement.

2. By using frequency conversion technology to eliminate on-site 50Hz power frequency interference, reliable data can be measured even in strong electromagnetic interference environments.

3. The overcurrent protection function ensures that the instrument is not damaged in the event of a short circuit or breakdown of the test sample.

4. Comes with standard capacitors and high-voltage power supply for easy on-site testing and reduces on-site wiring.

5. The instrument adopts a large screen LCD display, and the testing process is both intuitive and easy to operate through Chinese character menu prompts.

Wiring of temperature rise frequency conversion loss measurement device:

After wiring, it is necessary to pay attention to checking whether the wiring is correct and firm. During the test, if the high-voltage line is dragged to the ground or the measuring line is not firmly connected, it may cause ignition and damage the instrument.

When using the positive connection method for measurement, if the high-voltage line is dragged to the ground or the test object flashes, the instrument will be protected by an internal automatic power short circuit, which will burn out the fuse and still work normally.

3. After confirming that the wiring is correct, please stay away from the high-voltage terminal, then turn on the power and follow the menu prompts to operate. After the measurement is completed, the instrument displays the measurement results and stores them, emitting three beeps. If the forward connection method is selected incorrectly as the reverse connection method, the result will be no data or very low data. Conversely, if the reverse connection method is selected incorrectly as the forward connection method, the result will be the same as above! Both methods may damage the instrument! When using the forward or reverse connection method, the short-circuit plug must be inserted into HV1 and HV2, otherwise there will be no high voltage output if not plugged in. When making a CVT, before taking voltage from the socket and sending it to the CVT, the short-circuit plugs of HV1 and HV2 must be removed, otherwise high voltage will be carried on the HV socket, which may cause a safety accident!!

Notes:

1. This device is designed for short-term operation, so it is allowed to work at rated capacity for a long time and is not allowed to operate beyond rated current to prevent overheating

2. For newly installed and long-term unused transformers, measure the insulation resistance between coils and between coils and ground with a 1500 megohmmeter before operation. Only when the resistance value is not less than 0.5 megohms can it be used.

3. The use of intermediate current transformers must be reliably grounded to ensure safety.

4. When using, the flow should be slowly and evenly raised, and excessive vibration should be avoided during transportation.

5. The contact surface between the voltage regulator and the electric brush should be kept clean, and wiped clean with 90% alcohol dipped cotton yarn depending on the situation.

6. This equipment should be kept clean, ventilated, dry, and stored indoors.
