Intelligent control management system between skyscraper electrical equipment
The present invention relates to control treatment system between a kind of skyscraper electrical equipment, particularly the temperature between skyscraper electrical equipment, humidity, harmful gas, fire hazard are carried out to the computer management system of centralized detecting and control.
Along with the increase of urban population, construction speed is accelerated, and construction land is nervous, forces big and medium-sized cities to be built and constantly develops to high level.Although the construction of skyscraper can solve the problems such as urban land anxiety effectively, skyscraper is also with and is served unfavorable factor, except having an impact to the living environment of people, also produces larger impact to a large amount of electrical equipments be installed with in skyscraper.Some unfavorable factors that skyscraper environment brings mainly contain: high temperature, low temperature, moisture, mould and harmful toy, thunder and lightning, fire hazard, electrostatic, electromagnetic interference (EMI) etc.In order to ensure that electrical equipment holds reliable function and the adaptive faculty to environment in the continuation of insurance of these environment relayings, just different protection countermeasure must be taked according to its different installation environment.Although electrical equipment is in Design and manufacture, just consider the installation environment of product and feature and take some safeguard procedures, but concerning the design in several serious fires person of construction work, also must according to environmental characteristic special in skyscraper, reasonably select different electronic machines & apparatus, in order to improve electrical, reliability that power supply-distribution system runs and there is rational economic and technique level.
Being generally every layer between current skyscraper electrical equipment establishes between one, in order to save space, become vertical row design (generally running through all floors), area be approximately 2-5 ㎡/, so be also called electric well, in skyscraper electrical equipment due to the electric equipment installed and circuit more, so control temperature, humidity and fire prevention, anticreep just more strict than low-rise building, for south China, Guangxi, Guangdong, Hunan, Sichuan, Guizhou, the feature of the weathers such as Hainan be that spring, there was dampness in the air and summer and autumn temperature high, the changeable condensation causing equipment of spring temperature, summer and autumn high temperature and equipment heating produce temperature rise, easily cause equipment failure (as device damage) and accidents caused hidden danger (as leakage fire).
Also have, some place in skyscraper is provided with steam, the equipment of hot duct or some dissipating high temperature, electrical equipment is in its vicinity installed and circuit all will be subject to the impact of hyperthermia radiation environment to some extent, its serviceable life is greatly reduced, in addition, of some electrical equipments itself is as transformer, the equipment such as diesel emergency generating set also give out high temperature, natural ventilation and radiating condition very poor, if do not taked forced draft measure, larger on the impact of electrical equipment, the capacity of switch can be made to reduce, electrothermal relay misoperation, the technical feature of electron device is destroyed.When electrical equipment and circuit work for a long time in high temperature environments, insulating material can be made to soften, so dry and cracked; When road is short-circuited, as can not be protection switch made in time to trip, the outer jacket of insulated conductor will be caused 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, makes the insulating material of electrical equipment shrink, hardening or embrittlement, 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, water pipe from freezing crack seepage will be caused, leading 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, the inside electric appliance installed near moist steam can permeate and be diffused into, serious meeting makes the inside of electrical equipment or outside condensation form moisture film, metal surface heavy corrosion, these components and parts electric properties can be caused to decline, the insulation resistance of material surface is fallen 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, insulating material accelerated deterioration.According to MEDIUM THEORY, ambient humidity increase can make the corresponding increase of dielectric conductivity, relative dielectric constant, medium consumpting angle tgδ, and breakdown field strength reduces.In electrical equipment use procedure, its insulating element can become fragile under the action of heat, and after vibrated, its surface has tiny crackle.Again due to electrical equipment after a period of operation, 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 when it adheres to dust), conductor connection place contact resistance is increased, causes local overheating.Particularly " going back to Nan Tian ", the effect that the metal of electrical equipment and non-metallic component can be subject to temperature, oxygen, humidity and dust common, makes the condition of work of electrical equipment more worsen, has 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, the serviceable life of electrical equipment will greatly reduce.When the insulating material of electrical equipment and metallic conductor are corroded to a certain degree, if under electrical equipment is still operated in the environment of humidity and high temperature, will the electrical equipment safe operation of serious threat equipment room, also the safe operation of the consumer of entail dangers to user, and electric leakage, short circuit may be caused, cause the generation of serious electric fault and accident.Once generation electric fault, gently then can electrical equipment be damaged, heavy then cause line short to damage other consumers, even may cause circuit, equipment spontaneous combustion, cause fire failure to occur, the safety of life and property of the serious threat people.Along with the raising that development and the people of modern science and technology require intelligent building, the number of devices between electrical equipment is also being on the increase, and high-tech, the expensive proportion shared by electronic equipment are also in increase.These equipment are once break down or moisture damage, and economic loss that will be huge, seriously affects the normal Working Life of people.
In domestic open source literature, few about the relevant report of dehumidifying, temperature control treatment technology fireproof research and apply between electrical equipment.Wherein: 1), the Chongqing Electric scientific experiment research institute Liu Hua operating environment of power distribution room adjusting and control instrument describing Chongqing Electric scientific experiment research institute and Chinese DianKeYuan cooperation and jointly research and develop such as brave.This adjusting and control instrument possesses the automatic operation being specifically designed to the cool-down dehumidification equipment such as Long-distance Control power distribution room air-conditioning, exhaust fan and dehumidifier.By running experiment, demonstrate the operation that temperature controller effectively can control the equipment such as air-conditioning, reach and improve operating environment of power distribution room, alleviate the object of the workload of maintainer.2), Yuan Tong Electron Technology Co., Ltd in Xiamen opens sunlight application and runs on μ PSD3234A single-chip microcomputer that 40MHz crystal oscillator has 8051 kernels and utilize I/O port communication and AD conversion DS18B20 temperature measurement device and HM1500 temperature measurement device, and data are delivered to computing machine main website by the RS232 serial communication of single-chip microcomputer by measurement result, and export 24V DC voltage by I/O port through Darlington transistor, directly or realize the automatic measuring and controlling of transformer and distribution power station humiture again through DC/AC Control exhaust fan, dehumidifier, air-conditioning node, alarm signal etc.This systematic difference, contributes to the running environment improving 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, setting up computer control system, ensureing that electrical equipment normally runs and also not seeing that open source literature is reported.
