D12-M.R-10~160 single-phase pole-mounted transformer
The structure of the single-phase coiled iron core pole-mounted distribution transformer is relatively reasonable. Its loss is decreased significantly. Single-phase transformation can occur in the very center of load, which lowers wire loss, improves the power supply reliability. It is widely applied to urban and rural distribution grid and residential communities to achieve outstanding economic and social benefits.
Executive standards
1. GB1094.1-2013 Power Transformer
2. JBT10317-2014 Technical Parameters and Requirements of Single-phase Oil-immersed Power Transformer
3. JB T10088-2004 Sound Level of 6kV~500kV Power Transformer
Product characteristics
1. Low iron loss and small no-load current
Since the coiled iron core is free from joints, all the magnetization and magnetic flow directions are the same as the rolling direction of silicon-steel sheets. After annealing, the coiled iron core of a balanced process loss coefficient gives better play to the orientation performance of silicon-steel sheets. As the conditions are the same, the no-load loss of the coiled iron core decreases by 7-10% and its no-load current decreases by 50-70% compared with the laminated iron core.
2. Low noise level
The joint-free coiled iron core structure is wound by special equipment to ensure the compact and integrated iron core. Its noise level is usually 5 dB lower than that of the laminated iron core under the same conditions.
3. Strong resistance to sudden short circuit and reliable running
The ability of a transformer to resist short circuit and its reliability depend on the "force of clamping, bracing and compressing". The force of clamping, bracing and compressing between the iron core and the coil is an issue that needs to be considered for the traditional laminated iron core transformer, while joint-free coiled iron core distribution transformers only need to consider the force of clamping, bracing and compressing of the coil, which better embodies the simple structure and good reliability.
