Refrigeration system for cooling outdoor intelligent box of intelligent transformer station

Abstract

The invention discloses a refrigeration system for cooling the outdoor intelligent box of an intelligent transformer station. The refrigeration system comprises an air compressor device, an air storage device, a purification separation device, an air cooling device and a refrigeration control device. The refrigeration system completely changes the history that the outdoor intelligent box of the intelligent transformer station has no reliable cooling facilities, effective cools the outdoor intelligent box, eliminates potential safety hazard, and ensures the normal operation of the system. The introduction of compressed air enables the intelligent box to have positive pressure, prevents external humid air or dust from entering, and ensures dry and clean air in the intelligent box. The refrigeration system uses a vortex tube for cooling, does not use electricity or any chemical substances, has no additional cooling device, and is highly efficient in energy use, economical and practical, and more suitable for a case where a number of the intelligent transformer station outdoor intelligent boxes are provided. A high-power air compressor is used for concentrated air supply and high-pressure air pipelines are laid along a cable trench to the intelligent box via various air supply branches. The refrigeration system is innovative in idea, simple and practical in structure, easy to operate and maintain, achieves automatic control, and is stable and reliable in performance and suitable for promotion.

Description

technical field [0001] The present invention relates to a refrigeration system, in particular to a refrigeration system used for cooling the intelligent terminal box of an intelligent substation (hereinafter referred to as the intelligent box). Background technique [0002] The smart substation adopts advanced, reliable, integrated and environmentally friendly intelligent equipment, with the basic requirements of digitalization of information, networking of communication platforms, and standardization of information sharing, and automatically completes functions such as information collection, measurement, control, protection, measurement and detection, and A new type of substation with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction. The outdoor smart box of the smart substation is a device that merges and synchronously processes the electrical quantities tra...

AI Technical Summary

Problems solved by technology

In the past, the smart box in the substation encountered the above-mentioned overtemperature problem during operation, and had to open the box door to ventilate and cool down. However, dust, insects and small animals are easy to enter the box during the process, and it is very easy to short-circuit the dense electronic circuits. Faults caused by breakdown will directly affect the all-round intelligent control of smart substations and cause equipment accidents in substations and even grid accidents

In response to the above situation, this field tries to use micro-air conditioners or semiconductor refrigeration to cool down, but there are disadvantages such as high equipment cost, complicated operation and maintenance, inconvenient installation, space occupation in the box, high power consumption, and short life.

So far, this field has not taken any effective cooling measures for the smart box of the smart substation, which has constituted a serious safety hazard to the smart box, the substation system and even the power grid, and needs to be resolved urgently
