Ultra light power frequency withstand voltage test device

summary:

Ultra light power frequency withstand voltage test deviceAs the main unit of high-voltage testing equipment, combined with control systems, voltage regulators, protective devices, etc., it conducts power frequency withstand voltage tests on electrical products, equipment, components, and insulation materials to assess the insulation level of the test sample, and can detect local defects of the test sample early and measure the ability of the test sample to withstand internal and external overvoltages. Its characteristics are small size, light weight, and easy installation and use.

Structure:

Ultra light power frequency withstand voltage test deviceFor indoor equipment, the iron core is made of high-quality cold-rolled oriented silicon steel sheets, and the structure is arranged in a core and horizontal manner. The core column is concentric with low-voltage winding, measuring winding, shielding, and high-voltage winding. The high-voltage winding is a multi-layer pagoda shaped trapezoidal structure, and the low-voltage winding is a cylindrical structure, with the shielding and iron core grounded together. The bottom of the fuel tank is equipped with movable casters (without casters below 5kVA), which can be moved freely on the ground, making it convenient for laboratory and field operations.

Technical Requirements:

1. Normal usage conditions:

(1) Altitude: The altitude of the transformer installation site shall not exceed 1000m. When the altitude exceeds 1000m, the external insulation of the transformer shall be classified into two levels: 2500m (greater than 1000m to 2500m) and 4000m (greater than 2500m to 4000m).

(2) Environmental temperature:

The highest temperature is+40 ℃, the highest daily average temperature is+30 ℃, the highest annual average temperature is+20 ℃, the temperature is -5 ℃ (indoor type), and -25 ℃ (outdoor type).

(3) Maximum relative humidity of the air:

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

(4) Installation location:

The installation site is free from gases, vapors, chemical deposits, dust, dirt, and other explosive media that seriously affect the insulation of the transformer, as well as places with severe vibrations.

(5) Waveform of power supply voltage:

The waveform of the power supply voltage is an actual sine wave with a frequency of 50Hz, and the power supply side should not be subjected to external atmospheric overvoltage.

(6) When using ultra light test transformers, their input voltage should gradually increase and reliable protective measures should be taken.
