Introduction:
1500 kva 11kv 22kv 33kv pad mount transformer is a type of box-type substation. Its core feature is to integrate the transformer body, high-voltage load switch, fuse and other components in the same oil tank, and adopt an oil-immersed structure to achieve a fully sealed and fully insulated design.
Core Technical Parameters and Structural Design:
Basic Parameters and Voltage Adaptability
| Capacity | 1500 kVA |
| Voltage | High voltage 11 kV, 22 kV, and 33 kV |
| Tap changer | ±5% or ±2 x 2.5% voltage |
| Cooling | Self-cooled (AN) is the primary design, with optional air cooling (AF) to enhance overload capacity. |
| Insulation | Mineral oil or environmentally friendly natural ester oil is used as the insulating oil. |
Structural Innovation and Reliability
Fully Sealed Design: Corrugated oil tank or expansion radiator, maintenance-free, moisture-proof, and dust-proof, with an IP54 protection rating, resisting coastal salt spray corrosion.
Winding Material: High-voltage windings utilize high-permeability silicon steel sheets and oxygen-free copper conductors, while low-voltage windings utilize copper busbars. Short-circuit impedance is 6% to 10%, providing excellent short-circuit resistance.
Application scenarios and installation standards:
Typical application fields
Industrial power distribution: Provides stable power supply for mine air compressors and production line equipment, supporting an instantaneous overload of 1.2 times.
Grid access: As a terminal substation, it connects 11kV/22kV/33kV transmission lines with 0.4kV distribution networks, and is suitable for upgrading rural power grids.
New energy support: Achieve step-up grid connection in photovoltaic, wind power and energy storage projects.
Installation environment requirements
Foundation and protection: The concrete base can bear a load of no less than 5 tons. A 1.7-meter-high protective fence is set up around it, and the distance from the building is no less than 1.5 meters.
Grounding system: The neutral point and the casing are grounded separately, with a grounding resistance of no more than 4Ω.
Coastal area adaptation: It needs to pass the salt spray test. It is recommended to choose a stainless steel casing and anti-corrosion coating.
