Transformer is one of the most widely used and most efficient equipment in electrical equipment. Generally, the efficiency of 10 (6) kv transformer is 98-99%. Although the efficiency of transformer is high, it is used as a power supply equipment and needs to be powered on for a long time. When the transformer capacity is not fully utilized, the operation efficiency is low. In addition, due to the three-phase imbalance of transformer, unreasonable load coefficient The power consumption is still considerable due to the long-term high position operation of the voltage tap changer. Although the power loss of transformer exists objectively, it cannot be said that such loss is necessary and impossible to reduce. As long as the transformer consumption reduction measures are appropriate and used reasonably, the purpose of energy saving and consumption reduction can be achieved. Our company has three low-voltage distribution rooms and five transformers (four 630KVA and one 1000KVA). The distribution system has a large capacity and many transformers. Its long-term operation status is relatively unreasonable, and the loss accounts for 30-60% of the total loss of the distribution system. Due to this situation, we carried out corresponding theoretical analysis on the use of transformers in 2007, The transformation measures were put forward and applied in the use, maintenance and overhaul of transformers throughout the year, which played a certain role in the overall energy saving and efficiency increase of the company.

Study on energy-saving and efficiency enhancing dust cleaning technology of bag filter
Reducing the working resistance of the bag can significantly reduce the energy consumption of the dust collector. Pulse cleaning is the main method to reduce resistance. The traditional sequential ash cleaning mode reduces the efficiency due to the interaction between boxes and between bag columns in the same box. The proposed "skip ash cleaning" mode is helpful to improve the ash cleaning efficiency.

1. Power transformer Design of simulation model
Under the programming environment of Matlab, this paper analyzes the current methods of transformer simulation. In the case of single-phase, the phenomenon of saturated and unsaturated inrush current and the characteristics of single-phase inrush current are analyzed. In the three-phase case, based on the piecewise fitting and curve compression method, the mathematical simulation models of three-phase transformers under the four most commonly used connection modes Yd11, Ynd11, Yny0 and Yy0 are established by using two modified arctangent functions and two modified arctangent functions plus two straight lines to simulate saturation, and are simulated in Matlab. By analyzing the waveform of three-phase inrush current and hysteresis loop, and the characteristics of three-phase inrush current, the main factors affecting the inrush current of three-phase transformer are summarized. Finally, the advantages and disadvantages of the two methods are analyzed, and a relatively perfect transformer simulation model is established.

How to strengthen power distribution transformer Optimize configuration
The protection configuration of distribution transformer mainly includes circuit breaker, load switch or load switch plus fuse. Load switch can save investment, but can not break short circuit current; The technical performance of the circuit breaker is good, but the equipment investment is high and the use is complex; The protection configuration mode of combination of load switch and fuse can avoid the use of circuit breaker with complex operation and expensive price. This paper briefly explains various protection configuration types of distribution transformer. Through analysis and comparison, it is proposed to strengthen the optimal configuration of distribution transformer protection and select a reasonable protection scheme, which can improve the reliability of distribution transformer protection action.

In the coal mine power supply system, in order to ensure the reliable operation of power equipment, two main transformers are generally set. In case of split operation, if one fails, the other can be used as standby protection. In the process of transformer operation, if the system voltage is too low, the equipment cannot guarantee normal operation; If the voltage exceeds its maximum allowable working voltage, it is also easy to burn electrical equipment, which is called transformer overvoltage.
