Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, and particularly to an on-line monitoring device for cooling water. Background Art

[0002] The SVC (Switching Virtual Circuit) water cooling system is applied to systems such as power grids to ensure that the heat generated by key devices such as high-voltage high-power thyristors during operation can be dissipated in time, thereby protecting the devices from overheating damage and ensuring the stable operation of the SVC equipment. The SVC water cooling system runs continuously for 24 hours, and data parameters such as water flow and pressure can be monitored during operation. However, due to the large number of connecting parts such as inlet and outlet pipe valves and instruments, it is easy for the cooling water to leak. In the initial stage of pipeline leakage, the cooling water is likely to splash, causing the valve body to short-circuit and burn out, resulting in the expansion of the accident. At present, it can only rely on personnel inspection, lacking effective alarm monitoring means in the initial stage of water leakage. Summary of the Utility Model

The leakage detection rope is used to be arranged under the floor of the SVC water cooling system, and the leakage detection rope is electrically connected to the alarm device. The leakage detection rope is used to detect the leakage situation of the SVC water cooling system.
