The use of 20kv distribution voltage power supply capacity can be increased, reducing the amount of land occupied,reducing capital investment,reduce losses and improve voltage quality.Separate power supply can also be implemented between two votage concersion extemal terminal series-parallel high coltage winding.
1.High mechanical strength, resistance to short-circuit capability, partial discharge, good thermal stability, safety and reliability, environmental protection, long service life.
2.Low loss, low noise, energy-saving effect,maintenance-free.
3.Good heat dissipation performance, over-load capacity,than forced air cooling load operation.
4.Good moisture resistance, adapt to high humidity and other harsh environments.
5.Small size, light weight, low footprint, low installation costs.
6.Security, fire protection, pollution-free, can be run directly on the load center.
Meanwhile equipped temperature monitoring and protection system. Intelligent signal temperature control system can automatically monitor and display three-phase windings of the same screen their operating
temperature, can automatically start and stop the fan,and alarm, trip settings and other functions.
Dry type transformer is in accordance with "GB 6450-86 "Dry-type Power Transformer", GB 10228-1997 "Technical Parameter and Requirement of Dry-type Power Transformer and "GB 1094.1-1996 "Power Transformer Section 1 General", and it is the Grade F or H insulation dry-type power transformer cast and molded by epoxy resin. The product has the following advantages:
1.High mechanical strength and strong short circuit resistance ability;
2. Good moisture resistance and run with 90% humidity;
3. Advanced structure, small dimension, light weight and low partial discharge;
4. High insulation level and equal electric field distribution;
5. Easy maintainability;
6. Strong heat dissipation, run with 150% rated load under forced air cooling;
7. Fireproof, explosion-proof, pollution-free and low-noise and able to be directly installed in the load center.
The product can be widely used in places with high fireproofing requirements, such as power transmission and transformation system, high building, commercial center, sport stadium, petrochemical enterprise, metro, station and airport. In China, the epoxy resin cast dry type power transformer has the richest manufacturing experience and the best running performance.
