Three-phase load balancing electric power protection system and method for field tent hospital

Abstract

The invention provides a three-phase load balancing electric power protection system for a field tent hospital. The three-phase load balancing electric power protection system belongs to the technicalfield of power supply and distribution of field tent hospitals, and comprises a generator set and a power distribution unit, wherein the power distribution unit comprises a power supply transfer boxand power distribution boxes, the power supply transfer box transfers electric power generated by the generator set to the power distribution boxes in tents, and the power distribution boxes convert athree-phase power supply into a single-phase power supply and a DC 24V power supply to be connected with electricity utilization equipment; and a power supply line in each power distribution box is provided with a phase sequence changeover switch, which can realize manual adjustment of three-phase load balancing. Through arranging a main controller in the power supply transfer box and arranging auxiliary controllers in the power distribution boxes, the three-phase load balancing electric power protection system realizes online automatic adjustment of three-phase loads; the three-phase load balancing electric power protection system adopts a full box group structure, thus is convenient for handling, airborne transportation and wiring; and the three-phase load balancing electric power protection system has the advantages of reliable performance and stable power supply, and meets the electricity utilization requirements of field tent hospitals in various centralized or decentralized deployment modes.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution for field tent hospitals, and in particular relates to a three-phase load-balanced electric power protection system and method for field tent hospitals. Background technique [0002] The existing field tent hospital power supply and distribution system is usually integrated on a trailer, which supplies power to the medical treatment, lighting, medical oxygen production, medical water production, heating and air conditioning and other power consumption units in each functional tent through the guarantee trailer. Each support trailer can support two tents, which has the advantages of concentrated functions, fast deployment and withdrawal, but for the full-featured and large-scale all-element field tent hospital, there are the following shortcomings: (1) It is not suitable for airborne transportation , for the deployment of all-element field tent hospitals, usually multiple supp...

[0002] The existing field tent hospital power supply and distribution system is usually integrated on a trailer, which supplies power to the medical treatment, lighting, medical oxygen production, medical water production, heating and air conditioning and other power consumption units in each functional tent through the guarantee trailer. Each support trailer can support two tents, which has the advantages of concentrated functions, fast deployment and withdrawal, but for the full-featured and large-scale all-element field tent hospital, there are the following shortcomings: (1) It is not suitable for airborne transportation , for the deployment of all-element field tent hospitals, usually multiple support trailers are needed to meet the power supply and distribution requirements, and the transportation capacity is greatly increased. Especially when the road is damaged, the containerization cannot be completely realized, which is not conducive to rapid delivery in the field; (2 ) The existing trailer-type power supply and distribution system does not have the function of three-phase load balancing, and is prone to faults such as tripping and power failure, and the output interface is limited, which does not meet the requirements of flexible layout and combination, and the wiring is not flexible
