Foreword

This standard replaces GB/T 12455-1990 "hotels, restaurants and rational use of electricity." This standard compared with GB/T 12455-1990, the main changes are as follows. --- Original standard in Chapter 4 of the "air conditioning system" made to supplement and improve more content, such as increasing the "air-conditioning energy-saving technologies, air Conditioning system maintenance "and so on; --- To increase the drainage system of rational use of electricity, including maintenance and other content; --- Increased its hotels and restaurants in the kitchen, swimming pool, laundry room and other special places of power requirements; --- Delete the original standard "cold" this part; --- Added "Building Automation" section, including the "Energy Management Information Systems and BA, cold and heat sources and air-conditioning system monitoring", etc. content; --- The original standard "electricity metering Assessment Analysis" section of the supplement and more perfect. This standard by the National Standardization Technical Committee for Energy Management and focal points. This standard was drafted.

3 power supply system

3.1 rational supply and distribution 3.1.1 substation should have two line power supply, it is important to be self-independent emergency power load. Its location should be close to the load center, According to the case load distribution, high-rise buildings should be in an intermediate layer disposed substation. 3.1.2 within the substation suffered power supply voltage terminals rated voltage tolerance of the normal range, the offset voltage electrical equipment value should not be large Rated voltage of ± 5%. 3.2 single-phase electrical equipment should be evenly connected to the three-phase network, voltage unbalance supply network should be less than 2%. 3.3 line loss rate to the receiving end of the electrical equipment, a transformer for power supply and distribution system line loss rate should not exceed 3.5%. 3.4 transformer selection, configuration and operation 3.4.1 According to the actual power load, the choice of energy-saving low-loss transformers, the rational allocation of capacity and the number of units of the transformer. 3.4.2 Transformer total loss minimization principle, optimizing transformer operation mode, economically rational allocation of electricity load. 3.5 rational allocation of reactive power compensation equipment, improve the power factor of electricity, electric power factor compensation to be 0.9 or more. 3.6 Variable equipment inside the substation should be equipped with appropriate measurement and measurement instruments. Monitor and record voltage, current, power, power factor, and there are Reactive power, reactive power, power measuring instruments accuracy class of 1.0 to 0.5. Nonlinear loads 3.7 electrical equipment is harmonic source, easy to cause the grid current and voltage waveforms, harmonic pollution, should be taken to suppress Measures harmonics, meet the requirements of GB/T 14549 requirements.
