Method and device for modular configuration of low-voltage power distribution system

Abstract

The invention discloses a method and a device for modular configuration of a low-voltage power distribution system. The device comprises a unit power distribution module mainly formed by a voltage transformer, an oil engine, an ATS change-over switch, an MTS change-over switch and a low-voltage power distribution cabinet, and the unit power distribution module comprises a main unit power distribution module and a spare unit power distribution module. The invention is characterized in that N extensible unit power distribution modules are configured in the low-voltage power distribution of buildings, and at least one extensible unit power distribution module in the N extensible unit power distribution modules is taken as the spare unit power distribution module, i.e. the N+1 configuration method is adopted so as to ensure that the double routes supply power for the proof load at the terminal; and when one main unit power distribution module in the N extensible unit power distribution modules is out of service or maintained, the spare unit power distribution module is enabled, the spare power supply is provided for the proof load in the broken or maintained main unit power distribution module. The invention has the advantages that the method and the device greatly save the construction cost, solve the problem of high difficulty of expansion of the low-voltage power distribution system, promote the safety of the system and play the roles of energy saving and emission reduction.

Description

technical field [0001] The invention is used in the composition mode and configuration scheme of the low-voltage power distribution system of the communication office building, especially a modular configuration method and device of the low-voltage power distribution system. Background technique [0002] The low-voltage power distribution system of the bureau building is the basis of power supply design. The low-voltage power distribution system designed in the traditional main building and standby configuration mode has high construction costs, great difficulty in capacity expansion, and certain security issues. [0003] In recent years, due to the rapid development of communication services, communication operators across the country have experienced a serious shortage of substation power distribution capacity and tight power supply. A large number of communication equipment that will be connected to the network cannot be powered on as scheduled, and even the area of ​​the...

AI Technical Summary

Problems solved by technology

[0009] The main and standby construction mode of the traditional low-voltage power distribution part directly leads to factors such as long-term no-load transformers and large power cable losses.
