Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As shown in Figure 1, it is an embodiment of a hollow thick-walled tubular wire. The lead wire 10 of the large current equipment is composed of a thick-walled hollow pipeline 120 with a circular cross-section, which is placed horizontally. The outlet end is connected with the upper insulating lead pipe 140 through the upper electro-hydraulic separation joint 130 . The upper insulating lead pipe 140 is connected with the gas collecting pipe 160 through the sealing joint 150 . The air collecting pipe 160 enters the cooling space of the condenser 80 through the intake pipe 210 . The condenser 80 is connected to the liquid return pipe 170 . The magnetic float level gauge 190 is connected with the liquid return pipe 170 through the connection pipe 180 . A pressure sensor 200 is installed at the lower end of the liquid level gauge 190 , an...

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...
