Valve Tower of Converter Valve and Its Water Leakage Detection Device

Abstract

The invention provides a converter valve tower and a water leakage detecting device thereof, thereby solving a problem of low reliability of the water leakage detecting device in the prior art. The converter valve tower comprises a tower body and a water leakage collecting tray disposed at the bottom of the tower body. A water leakage detecting device is arranged on the water leakage collecting tray and includes a water leakage detecting cylinder; and a water inlet for entrance of leak water into the cylinder is formed in the detecting cylinder. More than three floating blocks are arranged inthe water leakage detecting cylinder and are distributed around the e vertical axis of the water leakage detecting cylinder; baffles are arranged on all floating blocks correspondingly; and light transmitting holes through which optical signals pass are formed in the baffles. Optical signal transceivers corresponding to all baffles are arranged at the water leakage detecting cylinder; and the optical signal transceivers correspond to the light transmitting holes formed in the corresponding baffles are used for outputting optical connection / disconnection signals when the floating blocks drive the baffles to move up and down.

Description

technical field [0001] The invention relates to a valve tower of a diverter valve and a water leakage detection device thereof. Background technique [0002] DC transmission converter valve equipment usually uses high-power thyristors or IGBTs as the core power semiconductor devices. Due to the power loss of thyristors and IGBTs during operation, a large amount of heat is emitted. In addition, other electrical components in the converter valve, such as saturation Reactors, damping resistors, etc. will also generate heat during operation. Therefore, in order to ensure the normal operation of the converter valve, the converter valve in the prior art mainly uses water cooling to effectively dissipate heat and control junction temperature. Accordingly, a complete cooling water circulation system is installed in the valve tower of the converter valve. This system is composed of hundreds of water pipes of different sizes and shapes; The device will be damaged, and the cooling eff...
