General technical requirements for power supply system of communication bureau (station)ScopeThis standard specifies the basic principles and requirements of communication power supply systems, including the structure and form of power supply systems of various communication bureaus (stations). Power supply system, DC power supply system, lightning protection and grounding, technical performance requirements of main power equipment, power supply system monitoring, environmental conditions and other requirements. This standard is applicable to all types of communication station power systems.Normative ReferencesThe following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this document. For undated references, the latest version (including all amendments) applies to this document.

The introduction of external power The area reserved for power distribution, generator sets, and power battery rooms should consider long-term load requirements. The construction of power transformation, distribution and generator sets should be considered convenient for expansion. 3.3 The newly-built bureau (station) shall conduct an EMC environmental assessment in accordance with national environmental protection requirements. 3.4 Communication bureaus (stations) should give priority to using safe and energy-saving power supply methods and power equipment. The application of energy-saving equipment should not sacrifice communication equipment At the expense of the longevity of the equipment and reducing the safety of the system. 3.5 A monitoring and centralized maintenance and management system for the power supply system of the communication bureau (station) should be established, in line with the provisions of YD/T 1363, and gradually achieve fewer people or unattended. 3.6 The communication bureau (station) should have reliable overvoltage and lightning protection functions, and comply with the regulations of GB 50689.Reconstruction and expansion of the communications bureau (station), The grounding and lightning protection facilities should be improved according to the requirements of the specification to ensure the safety of communication. 3.7 The configuration of the power supply system should meet the requirements of reliability indicators. 4 Introduction of external electricity 4.1 The reliability and classification of the mains power shall be fully considered during the construction of the communication station. See the classification and unavailability index of the mains power supply mode in 11.1. In principle, the introduction of the first category of city power should be considered for the first type of station; the second category of communication bureau should consider the introduction of the second type of city power in principle, and when the e...... |
