Detailed introduction

   160KVA dry-type transformer is our company for many years using high-quality materials and advanced technology and production. It goes deep into the load center. It is mainly used in various power supply places with AC 50-60Hz and voltage less than 500V. All kinds of input and output voltage, connection group and tap line group capacity distribution of products can be designed and manufactured according to user's requirements. The utility model has the advantages of convenient, reliable, fire-proof, safe and energy-saving.

 160KVA dry type transformer

I. working principle:

The 160KVA dry-type transformer is a power frequency power supply with low-voltage working voltage of 220 V / 50 Hz or 380 V / 50 Hz. According to the principle of electromagnetic induction, the input voltage is changed to reach the high voltage required by the test.

2. Service conditions:

1. Ambient temperature: - 5 ℃~ 40 ℃

2. The relative humidity shall not exceed 85% (when the air temperature is 25)

3. The altitude shall not exceed 1000m

4. The harmonic content of input power supply shall not be greater than 3%

3. Usage and precautions:

1. Connect the working ground wire according to the wiring schematic diagram, and the shell and operation box (table) of the transformer must be well grounded.

2. Before connecting the power supply, the voltage regulator of the operation box (table) must be adjusted to zero. After the power is connected, the green indicator light will be on. Press the start button, and the red indicator light will be on, indicating that the transformer has been powered on and waiting for voltage rise.

3. Rotate the pressure regulator handle clockwise and uniformly to boost the pressure, and pay close attention to the instrument indication and the condition of the tested object.

4. After the test, the high voltage should be reduced to below 20kV at a constant speed within 5 seconds, then the stop button should be pressed and the power supply should be cut off. Unless allowed by the test, sudden power failure is not allowed.

5. In the test, if the test object is short circuited or broken down, the over-current relay in the operation box (stand) will work smoothly. After the power is cut off, the voltage regulator should be returned to the zero position immediately.

4. Application occasion:

Widely used in subway, high-rise buildings, airports, stations, wharves, industrial and mining enterprises and tunnels, and the use of imported equipment.
