Embodiment Construction

[0025] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] This embodiment provides a fixed compressed air foam fire extinguishing system for an ultra-high pressure converter station, such as figure 1 shown. The input of the foam generating device is water, foam liquid and air. After internal mixing, the compressed air foam fire extinguishing medium is exported. The flow of water, foam liquid and air is controlled by the foam generating device controller; after the foam fire extinguishing medium is generated, it passes through the foam outlet The valve is delivered to the fire-fighting foam gun interface valve, the mobile robot interface valve and the 4 partition selection valves. The 4 partition selection valves correspond to the extreme I high, extreme I low, extreme II low and extreme II high of the UHV converter station respectively. There are 6 converter transformers equipped with 6 spri...

Abstract

The invention discloses a fixed compressed air foam fire extinguishing system for an extra-high voltage converter station and a control method. The system comprises a CAFS linkage control system, a foam generating device, a foam generating device controller, a mobile fire-fighting robot interface valve, a fire-fighting foam gun interface valve, a partition selection valve and a plurality of extra-high voltage converter station partitions. The CAFS linkage control system is used for collecting the switching signals of all the valves and determining the control signals of the foam generation device according to the switching signals of all the valves, so that the foam flow of the foam generation device is automatically adjusted in real time, and the intelligent degree and the operation stability of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of fire control, and particularly relates to a fixed compressed air foam fire extinguishing system and a control method for an ultra-high pressure converter station. Background technique [0002] In recent years, UHV converter transformers have exploded and caught fire, causing serious equipment burnout. The UHV converter has a large oil storage capacity and high operating temperature. Once a fire occurs, it is easy to form a high-temperature hot oil fire, which is very difficult to fight. The fixed compressed air foam fire extinguishing technology has the advantages of good fire extinguishing and cooling efficiency, good coverage effect, and water consumption saving. It is suitable for fire fighting of large transformers in UHV converter stations. Advanced fire-fighting technology for station fire-fighting capabilities. [0003] At present, the UHV converter station has begun to install CAFS as a means of...
