product description

The test of high voltage test transformer is the necessary test equipment for the detection and preventive test of electric power equipment.With the development of electric power industry in our country, the voltage level of the test transformer is getting higher and higher, and the oil insulation test transformer is in volume and weight (SF6) to the application area of electric power equipment.With the development of basic science research, the application of new materials and new technology, the new insulating medium SF6 gas is pushed into the field of electric power equipment application. Fluoride gas good insulation and arc performance, and non-flammable, making it as a new insulating medium to be widely used power system.

I plant after years of efforts to study the success of the inflatable ultra-light test transformer, the product compared with the oil-immersed test transformer with small size, light weight, no oil pollution, from climate change, corona extremely small Advantages, a single voltage up to 300KV.

Equipment protection

1) Keep the equipment clean.

2) regularly check the equipment pressure, found that leakage should be promptly contact with the factory.

3) When the air pressure ≤ 0.2Mpa, it should be timely qi.

4) equipment transport not allowed to tap.

Equipment Repair

Equipment from the factory the following three years to implement the following three packs:

High voltage coil short circuit or breakdown.

2. Low voltage coil short circuit or burned.

3. The shell is not well leaked.

4. All faults caused by product quality.

5. Instrument coil burned out of the scope of the three packs.

Precautions

1. Current limiting resistor setting, power frequency withstand voltage by 0.5 ~ 1Ω / V, DC test by 5 ~ 10Ω / V. The size of the resistance can be distilled water, water and salt in different proportions of deployment.

2. In the case of high-voltage output, and the high-pressure side without any load conditions, is strictly prohibited directly disconnect the power, should first drop the regulator to zero and then disconnect the power.
