Overview
Capacity range of 100-200kva, suitable for 10kV distribution network as neutral insulation system, or light resistance grounding system, and 400V system is a three-phase four-wire neutral direct node system.Complete set of strong, reliable power supply, small size, light weight, low noise;It has
ring network type and terminal type cable outgoing line.This product enables 10KV power network to go deep into the load center, reduce line loss,improve the reliability of power supply, beautify the urban environment, and is suitable for urban network transformation.
 

Operation Condition
●Altitude: s3000m
●Environment temperature range
●Temperature: Maximum monthly mean temperature +30°C, Minimum monthly mean temperature +20°C
●Relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%
●Shockproof level: horizontal acceleration 0.4m/s2
●Installation environment: the surrounding air is not subject to corrosion, flammable gas and other obvious pollution, the installation site without violent vibration

Structure Characteristics

●Compared with the "9" type transformer, the no-load loss of this product is reduced by 30.12% and the annual operating cost is reduced by 20.03% on average. The noise of the product is low, for environmental protection products.
●The transformer body, high voltage load switch (or high voltage load transfer switch), fuse, no excitation tap switch and so on are all placed in the fully sealed oil tank to improve the utilization rate of space. Its volume is only equivalent to the same voltage grade, the same capacity of the combined transformer (also known as European transformer) about 1/3, the weight is greatly reduced.
●Plug- out cable head, easy and flexible operation. .
●High and low pressure rooms are isolated and interlocked. When the door of the low-voltage room is opened, the door of the high-voltage room is opened. The high-voltage terminal is fully insulated and safe.
●Adopt two - stage fuse (backup current - limiting fuse, plug - in fuse) combination of all - obstacle protection, safe and reliable, flexible operation fuse replacement convenience.
●The oil tank is a fully sealed structure, and the oil inside the tank is isolated from the outside world. No leakage, no maintenance.
●Strong resistance to short circuit, high reliability.
