Three-phase load-balanced power protection method for tent hospitals in the field

Abstract

The invention provides a three-phase load balanced power guarantee method for tent hospitals in the field, which belongs to the technical field of power supply and distribution for tent hospitals in the field. The phase sequence transfer switch of the power distribution box can transfer the power distribution box under the phase sequence with the heavier load to the phase sequence with the lightest load, or detect the connection of all electrical equipment connected to it through the auxiliary controller in the power distribution box phase sequence of the power supply, and feed back the phase sequence information of each power distribution box to the main controller. The controller sends out control commands to control the power distribution box of the power supply line with the heaviest load to switch to the power supply line with the lightest load, so as to realize online automatic adjustment of three-phase loads to meet the needs of various centralized or decentralized deployment methods for field tent hospitals power requirements.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution for tent hospitals in the field, and in particular relates to a three-phase load-balanced power guarantee method for tent hospitals in the field. 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 support tra...

[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
