Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire handling of wind power converter cabinets, and specifically relates to an intelligent fire handling device for wind power converter cabinets based on temperature-controlled perfluorohexanone. Background Art
[0002] The existing double-fed converter cabinets of wind farms are generally weak in terms of safety and fire protection. They are mainly inspected and patrolled by wind power maintenance personnel on a regular basis. The personnel open the cabinet door to visually check for abnormal conditions in the cabinet. If any abnormality is found, they notify the manufacturer to come and deal with it. The manufacturer then goes to the site to conduct a detailed inspection of each module in the double-fed converter cabinet, including the power module, control module, and grid-connected module. Maintenance experience data shows that the temperature rise of the double-fed converter cabinet, mainly the IGBT and other power modules, is obvious, and it is easy to explode and cause fire. The installation location of the wind farm is relatively remote, generally in the ocean, islands, hills, mountains, etc., with poor roads and sparse personnel. Some mountain wind farms are surrounded by rich meadows and vegetation, so once a fire occurs, the hazard is extremely high.
[0003] The wind power double-fed converter cabinet adopts the method of regular inspection and patrol by personnel to achieve safe fire protection of the wind power double-fed converter cabinet. There are the following problems:
[0004] 1. Because wind farms are installed in remote locations, some are on top of mountains, some are on hills, some are on the ocean, and there are even meadows and vegetation around them. If the fire monitoring of the double-fed converter cabinet adopts the method of personnel inspection, the fire will not be discovered in time and it will be difficult to deal with it effectively and promptly. Once a fire occurs, the damage will be extremely great.
[0005] 2. The electrical environment of the wind power double-fed converter cabinet is as high as more than 400 volts. It is quite dangerous for inspectors to open the cabinet door and check with the naked eye, which endangers the personal safety of inspectors.
[0006] 3. Wind farms are installed in relatively remote locations, some on mountain tops, some on hills, and some on the ocean. Wind farms generally have dozens or even hundreds of wind towers. Each wind tower contains a wind turbine double-fed converter cabinet. In addition, inspection personnel inspect several wind farms. Such an actual environment cannot ensure that all inspection personnel are in place.
[0007] 4. Personnel inspections are generally carried out during the day or when weather conditions are good. It is impossible to carry out inspections and patrols around the clock, which means that fires cannot be discovered in time.
[0008] 5. Personnel inspections are only visual inspections on site, but they do not carry fire extinguishing agents with them. Even if a fire is discovered at the first time, it is difficult to spray the fire extinguishing agent in time to deal with it, and it is even impossible to spray automatically. Utility Model Content
[0009] The utility model aims to provide a wind power converter cabinet fire intelligent handling device based on temperature-controlled perfluorohexanone to solve the problem of untimely handling and poor handling effect of fire in wind power converter cabinets in existing wind farms.
[0010] The technical solution adopted by the utility model is as follows:
[0011] A wind power converter cabinet fire intelligent handling device based on temperature-controlled perfluorohexanone, comprising an MCU main control module, wherein the MCU main control module is signal-connected to a wireless data transmission module, a perfluorohexanone injection drive module, a power supply processing module, and a thermistor fire detection module; the thermistor fire detection module comprises a plurality of thermistors arranged next to a functional module in the wind power converter cabinet; the perfluorohexanone injection drive module is arranged in the wind power converter cabinet; and the wireless data transmission module is signal-connected to a remote control system.
[0012] Furthermore, the power processing module is an AC220 power conversion device.
[0013] Furthermore, the functional modules include a power module, a control module, and a grid-connected module.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0015] 1. In the utility model, the AC220 power conversion device converts the power into the required DC5V and DC3.3V to meet the working needs of the entire device; a thermistor is set next to the functional module in the wind power converter cabinet to monitor the fire environment of the functional module 24 hours a day. When a fire occurs in the wind power converter cabinet and ignites the thermistor, the MCU main control module sends a command to start the perfluorohexanone fire extinguishing agent to automatically start the perfluorohexanone injection drive module in the wind power converter cabinet to spray the perfluorohexanone fire extinguishing agent to extinguish the fire; the wireless transmission module is used to transmit the fire alarm information to the distribution monitoring center when starting the perfluorohexanone fire extinguishing agent injection, or the MCU main control module transmits the fire alarm information to the distribution monitoring center through the wireless transmission module. The module receives remote commands from the remote control system. Since the perfluorohexanone fire extinguishing agent adopts a diffuse, full-coverage, physical and chemical dual cooling mode for fire extinguishing, it has high fire extinguishing efficiency, is inactive to ozone, has a low greenhouse effect index, and is non-conductive, so it can achieve live fire extinguishing without short circuit. After the fire is extinguished, it does not affect the continued operation of the electrical system and does not require on-site maintenance. Compared with other gas fire extinguishing agents, it has unique environmental protection performance, excellent electrical insulation performance and safety of use. While realizing automatic disposal of fire in the wind power converter cabinet, it also protects the equipment from secondary damage, effectively solving the problem of untimely fire handling and poor handling effect in the existing wind power converter cabinet.
