Abstract
The invention provides an intelligent distribution panel for a weak current integrated uninterruptable power supply (UPS) system of a metro, comprising circuit breakers, an alternating current contactor, a relay, a programmable logic controller (PLC), an analog quantity module, a communication module, transducers and a text display. The intelligent distribution panel is characterized in that the above components organically form multiple groups of power supply circuits with different set power supply time segments in 1-150 minutes; and when reaching the set time limit, the power supply circuits are opened. When the power supply source has failure or faults, the weak current integrated UPS system can ensure continuous work and use the maintenance-free batteries as loads to supply power, and meanwhile, the power supply circuits of each system are respectively configured according to the power supply time needed by each system to output the power supply sources, and when each output circuit reaches the backup time required by design of each system, such as 5 minutes, 10 minutes, 15 minutes and the like, the intelligent distribution panel for the UPS automatically disconnects the output of the circuit, thus achieving the aim of saving power consumption.
Description
Technical field
The invention belongs to the power supply unit technical field, specifically relate to a kind of intelligent power distribution screen of subway weak current comprehensive ups system.
Background technology
Promotion and application along with the ups system centralized power supply system, and to continuous technological improvement of product and process innovation, will realize the management of ups system intelligent power distribution, improve utilization of power, reduce the battery input, thereby make in the UPS process of construction investment excessive, battery maintenance renewal cost height, the battery load-bearing, the space investment is too high, utilization of power is unreasonable, power supply is controlled problems such as being difficult to adjustment and is progressively solved, number of batteries and space hold had so both been reduced, reduce construction investment and maintenance cost again, simultaneously, because the minimizing of number of batteries, the raising of battery utilization ratio and the intelligent management of distribution, thus electric energy effectively utilized, cut the waste, also reduce because the environmental impact that battery operation and old and useless battery treatment are brought.
Enforcement by the intelligent power distribution scheme, can play certain optimization function to the UPS main frame type selecting of comprehensive ups system and the capacity configuration of storage battery, therefore, aspect UPS main frame and storage battery, can save part investment (the investment situation differences that different UPS schemes are saved).By increasing the part investment of intelligent power distribution, the integral body investment that brings comprehensive ups system descends, and has improved the intelligent degree of whole system simultaneously, has positive effect.
The comprehensive ups system of subway is more and more approved by the expert, not only can effectively reduce the integral body investment of UPS, can also save the maintenance cost of operation management.Intelligent power distribution occurs the new distribution demand that supplies down as comprehensive ups system will certain market prospect.Intelligent power distribution screen and UPS carry out the function combination, carry out centrally connected power supply, further optimizing equipment disposes and reduces the usable floor area of subway canyon, thereby help controlling the integral body investment of whole comprehensive ups system, be convenient to distribution management, the load monitoring of whole electric power system, improved system availability.In actual use, the required preparation time of the load of different brackets is also inconsistent, therefore can be according to the different reserve work duration of important level definition of load, manage by intelligent power distribution, the gradation of many grades of realization load is given, the management of realization intelligent power distribution improves utilization of power, reduces the battery input.
Summary of the invention
The object of the invention be to provide a kind of efficiently, reliably, importantly can save the intelligent power distribution screen of the subway weak current comprehensive ups system of back-up source.
In order to realize above purpose, technical scheme of the present invention is as follows: be made up of circuit breaker, A.C. contactor, relay, Programmable Logic Controller (PLC), analog module, communication module, transmitter, text display; It is characterized in that: above-mentioned each components and parts organically constitute the some groups of current supply circuits of setting different power-on time sections between 1～150 minute, to prescribe a time limit the current supply circuit open circuit when arriving when setting.
Further, described current supply circuit comprises 5 minutes current supply circuits, 10 minutes current supply circuits, 15 minutes current supply circuits, 30 minutes current supply circuits, 60 minutes current supply circuits and 120 minutes current supply circuits.
Also include Remote Control Interface RS485/422/232, remote monitoring is monitored and realized to the UPS monitoring equipment to the operating state of intelligent power distribution screen.
Compared with prior art, when power supply power failure or fault, weak current comprehensive ups power system can guarantee continuous operation, is electric by maintenance-free battery, simultaneously, according to the required power-on time of each system, dispose each system's current supply circuit respectively, the output power supply, each output loop reaches the preparation time of each requirement of system design, during as 5,10,15 minutes etc., the output in this loop of UPS intelligent power distribution screen automatic disconnection reaches the purpose of saving power consumption.
