Supporting type lifting fire extinguishing system suitable for converter valve

Abstract

The supporting type lifting fire extinguishing system suitable for the converter valve comprises a lifting module, a fire extinguishing monitoring module, a fire extinguisher module and a central control platform. The lifting module comprises a longitudinal rail, and the fire extinguishing monitoring module can move up and down along the longitudinal rail; the fire extinguishing monitoring module collects video images and infrared images of a converter valve tower and sends the video images and the infrared images to the central control platform. The fire extinguisher module comprises a fire extinguishing tank and a spray head, the fire extinguishing tank is arranged at the top end of the longitudinal rail, and the spray head is arranged on the fire extinguishing monitoring module and can move up and down along with the fire extinguishing monitoring module; and the central control platform judges whether a fire occurs or not according to the infrared image, if the fire occurs, an alarm prompt is given, a fire occurrence valve layer is judged, and the lifting module is controlled to drive the fire extinguishing monitoring module to drive the spray head to the fire occurrence valve layer to extinguish fire. The stable lifting of fire extinguishing, the reliability of fire extinguishing starting and the stability and high efficiency during fire extinguishing are guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a support type lifting fire extinguishing system suitable for a converter valve. Background technique [0002] The HVDC transmission system is mainly composed of five parts: the sending-end AC system, the rectifier station, the DC transmission line, the inverter station, and the receiving-end AC system, the most important of which is the converter station, and the converter valve of the converter station is The most important thing of the entire DC transmission system is to realize the functions of AC to DC and DC to AC, which is equivalent to the "heart" of DC transmission. Therefore, ensuring the reliable operation of the converter valve is particularly important for the DC transmission system. [0003] The converter valve is composed of thyristors, damping capacitors, voltage equalizing capacitors, damping resistors, voltage equalizing resistors, saturable reactors, thyris...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no practical and effective fire extinguishing plan for the converter valve. Generally, manual fire extinguishing is used whether the inspection corridor is far away from the valve tower, or the fire is manually extinguished by a lift truck. The fire will spread for a long time. The fire extinguishing system on one side of the tower swayed back and forth during fire extinguishing due to lack of a reliable support structure, and the fire extinguishing efficiency was low; the scissor suspension system of the same method was also too large and difficult to install the suspension. The scissors placed on the wall of the valve hall For a distance of about 8 meters, the scissor hydraulic system placed on the wall of the valve hall has a slow expansion speed. In case of signal interference, its fire extinguishing efficiency is also greatly reduced
