Intelligent control management system between skyscraper electrical equipment
Technical field
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.
Background technology
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.
