2. Structure:

The GCQB series high-voltage test transformer is an indoor equipment. The iron core uses high-quality cold-rolled grain-oriented silicon steel sheets, with a core-type, horizontal placement structure. The core column is concentrically equipped with a low-voltage winding, a measuring winding, and a high-voltage winding. The high-voltage winding is a multi-layer pagoda-shaped trapezoidal structure, and the low-voltage winding is a cylindrical structure. The design is compact and exquisite, can be moved freely on the ground, and is convenient for laboratory and field operations.

6. Technical Requirements

1. Normal Operating Conditions:

Altitude:

The altitude of the installation site of the transformer shall not exceed 1000m. When the altitude exceeds 1000m, the external insulation grading of the transformer is according to 2500m? (greater than 1000m to 2500m) and 4000m? (greater than 2500m to 4000m).

(2) Ambient Temperature:

Maximum air temperature +40℃, maximum daily average temperature +30℃, maximum annual average temperature +20℃, minimum air temperature -5℃

(3) Maximum Relative Humidity of Air

When the air temperature is +25℃, the relative humidity shall not exceed 90%.

(4) Installation Site

The installation site shall have no gases, vapors, chemical sedimentary dust, dirt, or other explosive media that seriously affect the insulation of the transformer, and no places with severe vibration.

Power Supply Voltage Waveform:

The waveform of the power supply voltage is practically sinusoidal, with a frequency of 50Hz, and the power supply side shall not be subjected to external atmospheric overvoltages.

When using the test transformer, the input voltage should be gradually increased, and reliable protective measures should be provided.
