Power supply system for refrigeration container in railway storage yard

Abstract

The invention discloses a power supply system for a refrigeration container in a railway storage yard. The power supply system comprises a power supply pile arranged on the floor at the edge of the railway storage yard, and further comprises a container power supply conversion switch, a container power supply socket and a power supply pile power supply socket which are arranged on the side surfaceof the bottom of the first layer of container side by side, wherein two or multiple layers of containers can be stacked at the top of the first layer of container according to a matching result of the area of the railway storage yard and the number of containers on a train; and container power supply conversion switches, container power supply sockets and power supply pile power supply sockets are arranged on the side surfaces of the bottoms of the two or multiple layers of containers side by side. According to the power supply system for the refrigeration container in the railway storage yard, a "one pile to two box" or "one pile to multiple boxes" power supply mode that charging pile supplies power to the containers and/or the charging pile supplies power to the first layer of containerand the first layer of container supplies power to the two or multiple layers of containers is realized, so that a refrigeration container power supply scheme is optimized, which makes the power supply mode for refrigeration containers is more flexible, and the power supply fault rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and more specifically relates to a power supply system for refrigerated containers in railway yards. Background technique [0002] With the continuous improvement of people's living standards, the pursuit of product quality is also getting higher and higher. In order to maintain the high quality of the product, some products need to be stored and transported in low temperature freezer. The traditional road refrigerated transportation can no longer meet the demand. In this context, the railway cold chain logistics came into being. The transportation of railway cold chain logistics mainly depends on large and medium-sized refrigerated containers. A refrigerated container refers to a special container that has good heat insulation and can maintain a certain low temperature requirement, and is suitable for the transportation and storage of various perishable foods. At present, domes...

AI Technical Summary

Problems solved by technology

Therefore, this power supply method requires more power supply sockets, resulting in more power supply piles in the refrigerated container yard and increasing the yard area

In addition, there is only one power supply port of the refrigerated container. When the power supply port fails, it cannot be repaired in time, which will cause the items in the refrigerated container to be unable to keep warm and fresh
