Abstract: A machine in the production process , heat loss is inevitable, resulting in excessive heat loss machine kept warm , potentially increasing the power consumption. So long consumption continues, you will be a big loss. Low efficiency power supply system
1 , irrational allocation of transformers and distribution lines and distribution system in the plant for maximum energy is power transformers and distribution lines . And changes due to changes in market demand for the factory production process , often appear in the design configuration of the power transformer capacity does not match with the actual load , such as transformer capacity is too large , the load is low, the transformer loss is big ; distribution line thickness and length of the unreasonable , not standardized, but also led to a substantial increase in line losses .
2 , electrical equipment obsolescence current Chinese mining industry also has a lot of transformers, motors , fans , oljvvowu pumps , compressors , welding machines and other equipment belonging to 6,70 generic products , equipment and power lines and some very old, these devices and power lines running low efficiency , power consumption and more waste is very large.
Low quality electricity grid serious pollution
1 , the impact of transient voltage and surge current number of industrial enterprises in power equipment and more , start frequent load changes, likely have an impact on the grid , causing transient voltage and surge current situation is serious, serious threat and affect other devices normal operation , causing the motor to accelerate the speed meter rise and wasted energy, decreased system power efficiency .
2 , the impact of industrial automation and the use of harmonic rectifier , inverter , SCR and other non-linear devices , will generate a lot of harmonics , the system voltage and current waveform distortion, deterioration of power quality , power consumption will not only increase also affected by electrical safety and equipment life , harmonic hazards have become the main power grid harm .
3 , the supply voltage is unstable industrial power transmission and transformation system load , wide distribution , electricity distribution peaks and troughs of time is very obvious, so the peak and trough periods of large voltage fluctuations will largely waste of energy , and it will worsen the quality of electricity , will not only increase power consumption but also affect the life and safety of electrical equipment.
