20KV S11/S13 oil-immersed distribution transformer

S11 and 513 series fully sealed oil-diffuse pressure commissioners are specially designed for power systems with AC 50HZ and 1 face constant voltage of 20kV and below, especially for the power distribution needs of petroleum, metallurgy, chemical, textile, light industry and other industries and dusty environments. This series of transformers adopts a fully sealed structure, which has the advantages of dustproof, moisture-proof, maintenance-free, etc., and can operate reliably in various industrial sites, providing stable and efficient power distribution solutions for enterprises.

Features:
1. Iron core structure
Cold-rolled silicon steel sheet with high magnetic permeability particle orientation! The new all-branch joint selection design, the core column is a multi-step stepped circular cross-section, and the iron yoke and the core adopt an equal cross-section structure to optimize the efficiency of the magnetic circuit
2. Winding design
Using corrugated oil duct process, no need to diffuse paint, through the case shrinkage belt binding fixed concentric coil structure, high-voltage winding set tap connection box cover switch I Note: tap voltage adjustment needs to be power-off operation
3. Security protection configuration
Standard: 30-2000kVA uniform pressure relief threshold
Optional: Support the installation of gas relay (including alarm/trip function)

4. Oil temperature monitoring system
The top of the whole series of fuel tanks is equipped with a glass thermometer socket (oil depth 120±10mm)!! 1000~2000kVA is additionally equipped with outdoor signal thermometer
15. Fuel tank technical highlights
Corrugated wall design
I surface dust spraying, paint film weather resistance
The corrugated sheet has both the functions of heat dissipation and volume compensation, and replaces the traditional oil conservator I vacuum oiling process:
Completely eliminate internal moisture, isolate oxygen and moisture1, significantly delay the insulation examination, and reduce the frequency of oil sample testing
