Abstract

The invention provides compact refrigeration equipment which is applied to cooling of a superconducting cable and comprises a cooling box body, a valve box body, an internal pipeline assembly and an external pipeline assembly, and the internal pipeline assembly is arranged in the valve box body. The external pipeline assembly is arranged outside the valve box body, and the external pipeline assembly, the cooling box body and the valve box body are integrally formed. A refrigeration equipment body is arranged in the cooling box body, and the external pipeline assembly, the internal pipeline assembly and a heat circulation heat exchanger form a liquid nitrogen circulation pipeline. The compact refrigeration equipment is compact in structural size and convenient to install, meanwhile, the cooling box body and the valve box body can protect important components of the refrigeration equipment, and component damage is reduced.

Description

technical field [0001] The invention relates to the technical field of superconducting cables, in particular to a compact refrigeration device for superconducting cables. Background technique [0002] In recent years, urban citizens have generally lowered their tolerance to electromagnetic effects and visual pollution caused by overhead lines, and it has become an inevitable trend for power supply and distribution lines to enter the ground. In order to meet the power demand of high power supply reliability, high power quality, and high load density, the construction cost of projects such as increasing circuit capacity and ring network entry into the ground using traditional technologies is extremely expensive, and it is even difficult to implement. This is a prominent contradiction faced by the power grid . High-temperature superconducting cables have many advantages such as low line loss, large transmission capacity, small corridor footprint, and environmental friendliness...
