Description

technical field [0001] The invention relates to the technical field of liquid leakage monitoring, in particular to a system and method for monitoring liquid leakage inside and outside an exciter cooler. Background technique [0002] The exciter of a large generator set is generally cooled by circulating air, and the cooling air is forced to circulate in the closed air path formed by the connection of the cooler, the air pipe and the casing of the exciter to take away the heat generated during the normal operation of the exciter. When the cooling air passes through the cooler, heat exchange occurs, and the heat is transferred to the cooling water in the copper pipe inside the cooler. Actual operating experience shows that the probability of leakage of the copper pipe inside the exciter cooler is very low, but it may still occur in some extreme cases. More often, leakage occurs at the external pipe joints or flanges of the cooler due to repair quality or poor sealing. Existi...

AI Technical Summary

Problems solved by technology

Existing exciter cooler leakage monitoring technology only involves single cooler internal leakage monitoring or cooler external leakage monitoring, but cannot effectively monitor the internal leakage and external leakage of the cooler at the same time

[0003] A single internal leakage monitoring of the cooler will lead to a higher probability of leakage at the external pipe joints or flanges of the cooler that cannot be monitored

The leakage of the external pipeline will cause the cooling capacity of the cooler to drop, and if the leakage is serious, it will cause the exciter to overheat, affecting the safe and stable operation of the generator set

[0004] A single monitoring of the external leakage of the cooler will lead to the failure to monitor the leakage of the inner copper pipe of the cooler, which has more serious consequences

If water leakage occurs in the inner copper pipe of the cooler during the operation of the exciter, the water will enter the interior of the exciter along the closed air path, causing a short circuit of the electrical components of the exciter, and further damaging the exciter
