Problems solved by technology

[0004] 1) The UPS of each weak current system is called for bidding separately, and the configured UPS brands are also different, which is not conducive to resource sharing and procurement of spare parts, resulting in heavy operation and maintenance workload and difficult battery maintenance.
[0005] 2) The conservative design of each weak current system on the grounds of "safety reserve" results in a much larger design capacity th

Embodiment Construction

[0033] The weak current integrated UPS system applied to urban rail transit projects according to the present invention includes a power input distribution system, a UPS and battery pack system, an intelligent switchboard system, and a UPS monitoring system; wherein:

[0034] The power input distribution system includes a first dual power supply transfer switch (hereinafter referred to as ATS), a circuit breaker for UPS main circuit and bypass power distribution, a transient voltage surge suppressor (hereinafter referred to as TVSS), the first dual power supply The two main and standby AC power inputs of the transfer switch ATS come from two different sections of 0.4kV busbars in the step-down substation of this site. One of the two power supplies is the main power supply, and the other is the backup power supply. Automatically switch to the backup power supply, the conversion time does not exceed 100ms, the two power supplies are switched by the first dual power supply switch ...

Abstract

The invention discloses a weak current integrated UPS (uninterrupted power supply) power system applied to urban mass transit and a power supply method. The weak current integrated UPS power system comprises a power source input distribution system, a UPS and storage battery system, an intelligent distributor system and a UPS monitoring system, wherein the UPS and storage battery system is connected with the power source input distribution system and the intelligent distributor system in sequence; and UPSs distributed in weak current systems of urban mass transit are integrated under the premise of meeting certain conditions and requirement, so that an integrated UPS power system meeting the requirements of relevant weak current systems can be formed, and UPS can be provided for weak current systems in the positions such as stations, car depots, parking sites and control centers. The weak current integrated power system can improve the reliability, availability and maintainability of the UPS system, reduce the investment in the UPS, reduce the configuration for the total capacity of the storage battery and increase the spare total capacity of each system, thereby facilitating centralized monitoring and management and maintenance of the UPS.

Description

technical field [0001] The invention relates to the technical field of UPS power supply, in particular to a weak current integrated UPS power supply system and a power supply method applied to urban rail transit projects. Background technique [0002] With the rapid development of urban rail transit, rail transit has become one of the most convenient, economical and efficient means of transportation for people to travel; at the same time, higher and higher requirements are put forward for the safe and reliable operation of urban rail transit. When the mains power supply to rail transit is abnormal for some reason, it will seriously affect rail transit. For this reason, relevant institutions have been continuously studying how to improve the continuity and reliability of power supply to important weak current systems of urban rail transit. [0003] At present, in domestic urban rail transit projects, weak current systems such as communication, signal, comprehensive monitoring...
