Abstract

The invention relates to a large current equipment pin equipment cooler circuit. It is characterized in that it comprises a large current device pin (10) and an evaporative cooling circulation system; the large current device pin (10) is formed by a solid conductor and circular or polygonal hollow conductor or hollow pipe conductor; it injects the evaporative cooling media in the hollow conductor. The current can lead the loss and the winding heats whose heat transmits to the cooling media of the hollow conductor, when the temperature lifts to the corresponding saturation temperature; the winding inner hollow conductor evaporative cooling media evaporates to form boiling heat transfer and then uses cooler to be liquefied, and then cycles.

Description

technical field

[0001] The invention relates to a self-circulation cooling circuit for lead wires of high-current equipment of electrical equipment, in particular to a self-circulation cooling circuit for lead wires of hydroelectric generators and high-current transformers. Background technique

[0002] With the development of large-scale electrical equipment, the increase in temperature caused by the increase of current and heat has become a bottleneck restricting its development.

[0003] According to different cooling methods, the cooling methods of lead wires are usually divided into two types: air cooling and water internal cooling. The air-cooling method reduces the current density by increasing the number of parallel branches and increasing the cross-sectional area of ​​the over-current, and adopts measures such as setting a windshield to appropriately reduce the over-current area at the upper end of the stator to increase the wind speed at the lead wire and achieve t...
