Intelligent control management system between the skyscraper electrical equipment
The present invention relates to control disposal system between a kind of skyscraper electrical equipment the computer management system of particularly temperature between the skyscraper electrical equipment, humidity, harmful gas, fire hazard being carried out to centralized detecting and control.
Along with the increase of urban population, construction speed is accelerated, and the construction land anxiety forces the big and medium-sized cities building constantly to develop to high level.Although the construction of skyscraper can solve the problems such as urban land anxiety effectively, skyscraper also is with and is served unfavorable factor, except the living environment to people exerts an influence, also a large amount of electrical equipments that are installed with in skyscraper is produced to larger impact.Some unfavorable factors that the skyscraper environment brings mainly contain: high temperature, low temperature, moisture, mould and harmful toy, thunder and lightning, fire hazard, static, electromagnetic interference (EMI) etc.Hold reliable function and, to the adaptive faculty of environment, installation environment that just must be different according to it is taked different protection countermeasure in order to guarantee electrical equipment in the continuation of insurance of these environment relayings.Although electrical equipment is in Design and manufacture, with regard to the installation environment of considering product and feature and taked some safeguard procedures, but concerning the design in several serious fires person of construction work, also must be according to environmental characteristic special in skyscraper, reasonably select different electronic machines & apparatus, in order to improve power supply-distribution system operation electrically, reliability and there is rational economic and technique level.
Be generally every layer between the skyscraper electrical equipment at present and establish one, in order to save space, become vertical row designs (generally running through all floors), area be approximately 2-5 ㎡/, so be called again electric well, interior because electric equipment and the circuit installed are more between the skyscraper electrical equipment, so control temperature, humidity and fire prevention, anticreep just more strict than low-rise building, take south China as example, Guangxi, Guangdong, Hunan, Sichuan, Guizhou, the characteristics of the weathers such as Hainan be that spring, there was dampness in the air and summer and autumn temperature high, the changeable dewfall that causes equipment of spring temperature, the temperature rise that summer and autumn, high temperature and equipment heating produced, easily cause equipment failure (as device damage) and accidents caused hidden danger (as leakage fire).
Also have, some place in skyscraper is equipped with steam, hot duct or some are distributed the equipment of high temperature, electrical equipment and the circuit installed in its vicinity all will be subject to the impact of hyperthermia radiation environment to some extent, greatly reduced its serviceable life, in addition, of some electrical equipments itself is as transformer, the equipment such as emergency diesel dynamo group also give out high temperature, natural ventilation and radiating condition are very poor, if do not taked the forced draft measure, impact on electrical equipment is larger, can make the capacity of switch reduce, the electrothermal relay misoperation, the technical feature of electron device is destroyed.Work under hot environment for a long time when electrical equipment and circuit, can make insulating material softening, so dry and cracked; When road is short-circuited, as do not made in time the protection switch tripping operation, will causes the outer jacket of insulated conductor to melt, catch fire, and then cause large-scale fire failure.
And northern, as some severe cold areas of northern China, the low temperature environment caused winter, make insulating material contraction, hardening or the embrittlement of electrical equipment, and the electric property of oil switch and oil-filled electric equipment and mechanical property reduce.Fire fighting water system in skyscraper can freeze because of the low temperature in winter.If do not taked effective antifreezing measures, will cause the water pipe from freezing crack seepage, lead to great electric equipment accident.
About wet gas environments, except above-mentioned said weather condition, the place that water plant in skyscraper, basement or water vapor are larger, near the inside electric appliance of installing moist steam can permeate and be diffused into, serious meeting makes the inside of electrical equipment or outside condensation form moisture film, the metal surface heavy corrosion, can cause that these components and parts electric properties descend, make the insulation resistance of material surface fall and insulate breakdown, the strength of materials reduces, dielectric loss angle increases, the malfunctioning and electric contact loose contact of components and parts etc.
Electrical equipment makes moist and can make the decreasing insulating of equipment, the insulating material accelerated deterioration.According to MEDIUM THEORY, the ambient humidity increase can make dielectric conductivity, relative dielectric constant, the corresponding increase of medium consumpting angle tgδ, and breakdown field strength reduces.In the electrical equipment use procedure, its insulating element can become fragile under hot effect, and vibrated rear its surface has tiny crackle.Again due to electrical equipment work a period of time after, will depend on certain dust on its surface, after making moist between electrical equipment, moisture will make the dust be attached on these crackles bring crack into.Under the acting in conjunction of moisture and dust, very low voltage also may cause electric discharge phenomena, makes insulating material damaged or puncture.
Under the effect of moisture and high temperature, the metallic conductor of electrical equipment also can oxidizedly corrode (particularly in the situation that it adheres to dust), and conductor connection place contact resistance is increased, and causes local overheating.Particularly, " going back to Nan Tian ", the metal of electrical equipment and non-metallic component can be subject to the common effect of temperature, oxygen, humidity and dust, make the condition of work of electrical equipment more worsen, and have a strong impact on the safe operation of electrical equipment.If do not take protection against the tide and temperature control measures between high-rise green building electrical equipment, will greatly reduce the serviceable life of electrical equipment.When the insulating material of electrical equipment and metallic conductor are corroded to a certain degree, if electrical equipment still is operated under the environment of moist and high temperature, electrical equipment safe operation that will the serious threat equipment room, the also safe operation of entail dangers to user's consumer, and may cause electric leakage, short circuit, cause the generation of serious electric fault and accident.Once the generation electric fault, gently can damage electrical equipment, heavy cause that line short damages other consumers, even may cause circuit, equipment spontaneous combustion, cause fire failure to occur, the serious threat people's safety of life and property.Along with the raising that the development of modern science and technology and people require intelligent building, the number of devices between electrical equipment also is being on the increase, and high-tech, the expensive shared proportion of electronic equipment are also increasing.The damage once these equipment break down or make moist, economic loss that will be huge, seriously affect the normal Working Life of people.
In domestic open source literature, few about the relevant report of dehumidifying between electrical equipment, the research of temperature control treatment technology fireproof and application.Wherein: 1), the Chongqing Electric scientific experiment research institute Liu Hua operating environment of power distribution room adjusting and control instrument of having introduced Chongqing Electric scientific experiment research institute and the common research and development of Chinese DianKeYuan cooperation such as brave.This adjusting and control instrument possesses the automatic operation of cool-down dehumidification equipment such as being specifically designed to Long-distance Control power distribution room air-conditioning, exhaust fan and dehumidifier.By running experiment, verified that temperature controller can effectively control the operation of the equipment such as air-conditioning, reach and improve operating environment of power distribution room, alleviate the purpose of maintainer's workload.2), the Xiamen sub-technology Co., Ltd. Zhang sunlight application of far switching on runs on the μ PSD3234A single-chip microcomputer that the 40MHz crystal oscillator has 8051 kernels and utilizes IO port communications and AD conversion DS18B20 temperature measurement device and HM1500 temperature measurement device, and measurement result is delivered to the computing machine main website by the RS232 serial communication of single-chip microcomputer by data, and pass through Darlington transistor output 24V DC voltage by the IO mouth, directly or again pass through the automatic measuring and controlling that DC/AC Control exhaust fan, dehumidifier, air-conditioning node, alarm signal etc. realize the transformer and distribution power station humiture.The application of this system, contribute to improve the running environment of transformer and distribution power station, promotes the reliable and stable operation of grid equipment.But, how to carrying out unified dehumidifying, the research of temperature control treatment technology fireproof between high-rise intelligent building electrical equipment, set up computer control system, guarantee that electrical equipment normally moves the open source literature report of also not seeing.
