Description
Technical Field
The invention relates to the technical field of urban switching station fire alarm, in particular to an urban switching station fire-fighting system.
Background
The city switching station is for fire prevention of general meaning relatively, and the computer lab has self characteristics, mainly embodies in following several: 1. flammable articles are various, a large number of instruments and equipment with complete functions and high prices, wires and cables and various storage media are arranged in a modern electronic communication machine room, wherein components and cable insulation jackets in the equipment are made of flammable materials such as carbolic acid fibers and polyvinyl chloride, and the flammable materials are easy to burn and cause disastrous results. 2. The fire disaster is induced by various mechanisms, and the generated hazards are various, and the fire disaster can be induced by various reasons, including traditional reasons and various reasons based on the characteristics of the electronic equipment room. According to statistics, among various reasons causing machine room fire, 28% of fire is caused by a machine room power supply system (an alternating current/direct current power supply, a battery, a generator, a power supply line and the like), 18% of fire is caused by other electrical equipment in a building where the machine room is located, wherein the electrical equipment comprises an elevator, an air conditioner, a heating device, a lighting system and the like, and 35% of fire is directly caused by components inside electronic equipment in the machine room. Once the equipment in the machine room is in fire, direct damage can be caused to the equipment, and the gas generated by burning special materials in the equipment in the machine room has strong corrosivity and can cause long-term damage to the equipment. 3. The equipment in the machine room is expensive, the sensitivity to fire is extremely high, compared with the prior art, the modern electronic equipment is increasingly advanced and the price is very expensive. Damage to one module will cause a significant loss. Along with the development of science and technology, electronic products are higher in integration degree and smaller in size, so that the fire hazard in a unit space is larger and larger. The equipment cabinet is generally changed from 4 meters to about 2 meters at present, and the equipment originally arranged in a plurality of rooms can be concentrated in one machine room, so that a fire disaster happens to one machine room, and the fire disaster has serious consequences on the facility and the electric power operation. In addition, due to the high integration of the equipment, the requirement of the equipment operation on the environment is higher and higher, and the temperature rise of components and parts till the combustion are easier to cause by the change of any temperature and humidity. 4. Air conditioning facilities are complete, fire detection is difficult, air conditioning systems are widely adopted due to the requirement of machine room environment, and smoke transmission and diffusion become easier.
However, the existing fire detection means in the switching station is insufficient, the traditional point type fire detectors are all in passive detection, and the installation positions are all on the top. Under the influence of air flow of air conditioner operation, smoke particles can be quickly diluted by the air flow, move along with the movement track of the air flow and cannot rise to the top in the initial stage of a fire, so that the point type smoke detector is not suitable for environments with high air flow, such as a machine room area; in summary, in the switching station and the operating environment thereof, the main reason that a fire may be caused is an electrical fire, and generally, the smoke amount is very small at the initial stage of the fire (smoldering fire stage), so that the fire is difficult to be found by the conventional fire alarm equipment, and early warning of the fire cannot be realized; meanwhile, for the alarm equipment which runs in the power station environment for a long time, the alarm equipment has the characteristics of humidity, dustiness, various space changes (narrow space and high space), strong airflow and the like, and brings great challenges for effective and long-term stable detection. Therefore, in the present day era where new technology and new products emerge endlessly, in combination with successful application experience of substations at home and abroad, it is suggested that in such environmental conditions, fire detection and alarm means with better detection effect, more advanced technology and simpler and more convenient maintenance should be adopted to achieve the purposes of comprehensive protection, early warning, early evacuation and disaster prevention, so as to better guarantee the normal operation of the power system and the safe power utilization of people.
