Abstract

The invention relates to a direct-current transmission converter valve tower and a water leakage detection system thereof. The direct-current transmission converter valve tower comprises the water leakage detection system, The water leakage detection system comprises a water accumulating tray, a detection device, a light emitting device and a light receiving device, wherein the detection device is fixed to the lowest position of the water accumulating tray and comprises a total reflection prism, and the light emitting device, the total reflection prism and the light receiving device form a sealed light path. The water leakage detection system further comprises a light shielding cover plate covering the detection device. According to the direct-current transmission converter valve tower and the water leakage detection system of the direct-current transmission converter valve tower, the total reflection prism is used as water leakage detection equipment, whether the water leakage situation exists or not is judged through whether the light receiving device receives light signals or not, and the reliability and the accuracy of water leakage detection are ensured.

Description

technical field [0001] The invention relates to a valve tower of a direct current transmission converter valve and a water leakage detection system thereof, belonging to the field of direct current transmission and transformation. Background technique [0002] The converter valve equipment is the key equipment in the HVDC transmission system, and the operation reliability of the converter valve equipment directly affects the working stability of the DC transmission system. The internal cooling system of the converter valve equipment mostly adopts water cooling mode. The complex water cooling circulation system is realized by the connection of multiple water pipe joints. During the long-term operation, these water pipe joints are prone to water leakage. Once the valve tower leaks, including The performance of product parts and components including electrical components will be greatly affected, which will pose a great threat to system safety. Therefore, effective detection of...
