Along with the progress of society, the economy has been rapid development, people's living standards have been greatly improved, China's economic and technology have been a good and fast development in the process of rapid development of technology, the power resources foundation. Continuous improvement of people's living standards is also inseparable from the continuous support of the power, the power resources and our study, live, work, production, etc. activities are inseparable, the current serious shortage of power resources, which requires that we conduct electricity resources when used to save, installation and construction in the power of communication, we should use energy-saving technologies.

 1. installation and construction of energy-saving electric power communication transformer to determine the position of technical applications

When the power-saving technology to go into communications installation and construction should be based on the specific circumstances of the site was carried out to determine the location of the transformer work. If the construction site near high-voltage power grid transmission, then you can set up step-down substation in the vicinity of the site, and the power from 6KV or 10KV reduced to 380 \ 220V, while requiring step-down substation location as possible location close to the load center. Here, I want to emphasize that the effective radius of the substation power supply must not be more than five hundred meters. If it is a large construction site can be more divided according to the specific use of several power supply electric power substation, but must do everything possible to shorten the length of the low-voltage lines, this can reduce the loss of voltage, so as to achieve savings energy, reduce investment purposes.

 2. Installation of energy-saving electric power communication transformer capacity selection techniques applied

 Installed in the power of communication technology in the construction of energy-saving transformer capacity selection, the selected transformer capacity can not be too small nor too big, if you choose the transformer capacity is too small, then the motor is slightly overloaded electrical equipment or capacity increase slightly when Since the transformer capacity is too small, can not afford so much current and voltage transformers will lead to burning or excessive heat. If you choose the transformer capacity is too large, it will lead to electrical equipment can not make full use of the capacity, which would result in the loss of power resources in large part, eventually leading to the loss of energy. When the transformer capacities should first calculate the load capacity of the transformer should be selected according to the calculated value of the load. For single transformer steady load, load rate generally eighty-five% or so, for those seasonal fluctuations or diurnal fluctuations transformers, and these are load power supply transformer transformer, transformer capacity to be a reasonable choice, transformers Number of units should also be a reasonable choice, but also in the peak time for proper and timely transformer overload operation. For those short-term load power transformer, must make full use of their overload.

3.Installation of energy-saving electric power communication technology applications of power lines, power factor improvement

The application of energy-saving technology to go into power communication installation is also required to improve the power factor of the power supply lines, the general supply enterprise in the supply line power factor selection generally relatively low. According to the survey, the general power supply line power factor companies select the above average at around 0.6, some enterprises in the supply line power factor choose even lower than 0.6 above. Therefore, I believe, will be applied to the power-saving technology to communicate among the installation and construction, we must increase the supply line of the power factor. We can improve the power factor of the power supply line from the administration to strengthen the construction of electricity, but also from the application of reactive power compensation equipment to improve power factor of the power supply line.

Conducted to strengthen the construction of electricity from the supply line management to improve power factor, to do to improve the motor and the load ratio of the transformer, motor and transformer load rate of scientific planning, to effectively do their best efforts to make the layout more power lines rationalization. From the application of reactive power compensation equipment to improve power factor of the power supply line to achieve power capacitor device applications in the supply lines.

How to compensate for capacity and decentralized electricity load is relatively small enterprises should improve their supply line power factor. For compensation capacity and decentralized electricity load is relatively small enterprises, to adopt ways to improve their low compensation supply line power factor, low-voltage capacitor dispersed in the workshop will be compensated to do so can be a good cross-section and distribution equipment to reduce the capacity of the line, so as to achieve the goal to reduce energy consumption. However, for those big compensation capacity and electricity load centralized enterprises, these companies want to improve the power factor of the power supply line, we must use high-pressure mixing this way, choose this way to maximize the power factor of the power supply line to improve and the maximum reduction in reactive power loss, the reactive power loss to a minimum.

 4. Installation of energy-saving electric power communication technology applications of balanced three-phase load

In the three-phase load balance, I believe, three-phase unbalanced load caused the main reason is the power of communication in the installation and construction, the two-phase and single-phase load loads more, plus random access power is severe, This has resulted in unbalanced three-phase load. Three-phase unbalanced load is a great harm, three-phase unbalanced load can make the neutral point potential has increased, if the three-phase load unbalance the situation is serious, it will cause the metal housing of the device on the ground discharge, thereby generating a spark.

　　　Three-phase load imbalance has severely affected the electrical safety, electrical safety from the perspective of three-phase load imbalance is not able to appear, but from the perspective of energy-saving, three-phase unbalanced load is one of the major causes of power loss, so we must pay attention to the three-phase load imbalance. Installed in the power of communication, it should be single-phase electrical equipment in accordance with the nature of the load is allocated evenly distributed to the three-phase above, so as to achieve each phase of the load as close to the ultimate do-phase load balancing.
