建筑电气工程针对问题防治预控保证电气系统正常
科学技术的前进在电力体系中体如今电气设备的宏大革新,各项电力设备的功用不断强大和完善,选用的资料牢靠性越来越高,若是仍然传承传统的描绘理念,选用传统的施工办法,将会带来许多疑问。例如:在曩昔,高压开关柜中的高压开关一般选用的是油断路器,构成设备体积大,需求较大的空间,在放火上也有所短缺;如今,真空断路器以及SF6断路被许多运用,步进大大减小了设备的体积,在短路容量上比较于油断路器也有较大的添加,一起还具有防火性。从总体上来区分,电气体系有强电和弱电之分,其间强电的施工包含有:变配电体系的装设,电力以及照明体系的施工,防雷接地体系的施工等等,关于变配电体系的装设来说,详细包含:高低压体系、变压器等设备;关于电力和照明体系来说,详细包含:对体系配电以及操控,室表里的遍地的照明施工;关于防雷接地体系来说,包含:雷电波的侵略防备,防雷电感等等。
Great innovation of science and technology progress in the power system in the body now electrical equipment, the equipment function has powerful and perfect, and data reliability with higher, if still inherit the traditional depiction of concept, selection of construction methods of traditional, will bring a suspicious ask. For example: in the past, high voltage switch in high-voltage switch cabinet are generally chosen oil circuit breaker, constitute a large volume of equipment, demand for larger space, on the fire on also has the shortage; now, vacuum circuit breaker and SF6 circuit breaker is many uses, step can greatly reduce the equipment volume, short circuit capacity in comparison in oil circuit breaker is added, together with the fire of. As a whole, distinguish, electrical system with strong and weak electricity points during construction, strong includes: variable power distribution system installation, construction of power and lighting system, lightning protection and grounding system construction and so on, on the transformation and distribution system installed, including details of : high and low pressure system, a transformer and other equipment; the power and lighting system, including details of the system: distribution and control, lighting construction everywhere inside and outside the room; on the lightning protection and grounding system, including: lightning wave invasion prevention, lightning protection inductance etc..
没有挑选合格的配管原资料,例如:正本大概挑选镀锌管的场合,选用了一般的黑铁管;正本大概运用金属管的场合,却选用了PVC管;在应运用厚壁管的场合运用了薄壁管;有的场合运用的钢管壁厚不合格,管径没有依照描绘的需求来组织;
Do not select qualified piping materials, for example: the original probably pick galvanized pipe of the occasion, the general black pipe; the original about using metal pipe of the occasion, the PVC tube; in the use of thick-walled pipe occasions using thin-wall pipe; steel pipe wall thickness at some occasions use unqualified, diameter does not according to the description requirement organization;
在暗埋的进程中,没有对施工进程进行有用监督,一旦维护层缺乏,就会构成规矩裂缝的呈现,严峻时甚至会致使管子的阻塞;在操作接地线进程中,关于一些运用的金属管,没有进行跨接接地线,或者是彻底有些原料,一切的管子悉数焊跨接接地线;
In the buried in the process, no effective oversight of the construction process, once the lack of maintenance, will constitute rules cracks appear, and even cause serious obstruction tube; in the operation process on the ground, some use the metal pipe, no cross the grounding line, or to some raw materials, all welding pipe all across the ground wire;
在管子需求弯折时,没有合理描绘弯折处管子的走向,致使管进盒不顺直,然后导致裂缝和烤伤;在吊顶内部,没有进行必要的穿管维护。
In the tube bending to demand, without reasonable depicted bending the pipe, the pipe into the box is not straight, and then lead to cracks and roast injury; in the ceiling, no maintenance through the necessary.
关于电缆的架起来说,常常会呈现以下一些疑问,有一些施工单位为了谋取私利,常常选用残次的产物,谎称产物;对运用的各种电缆不进行体系性的分类,常常呈现电缆的过错运用,由此构成施工现场的紊乱,更重要的是为今后的电力运转带来危险;许多时分电气的电力电缆和外表电缆混合在一起,构成了各类外表的测量误差和更为严峻的结果。对电缆的终端没有进行有用处置,详细来讲就是没有将电缆的桥架和支架做牢靠的固定和接地;在电缆的敷设时,没有描绘满足的曲折半径,在相应方位也没有设置标志牌等。
Set up on the cable, often appear some doubt, some construction units for personal gain, often using inferior product, that product; on various cable used without classification system, fault using often present cable, which constitutes the disorder in the construction site, but more importantly for the future of electric power operation risk; in many cases electrical power cable and the appearance of cable mixed together, constitute the measurement error of various kinds of appearance and more rigorous results. Terminal on the cable are not useful in detail disposal, is not of the cable tray and bracket fixed and reliable grounding; in the cable laying, radius of bend do not describe the content, in the corresponding range have no signs.
关于任何一个建筑物来说,避雷设备都是必不可少的。一般情况下,都是选用一般的元钢敷设,在实践的进程中,常常会呈现塔接长度缺乏,焊接口也常常呈现锈蚀等严峻表象,当支架之间呈现过大的间隔时,简单构成支架的掉落。别的,因为屋面的金属物一般没有作防雷接地处置,接地的主干线没有和相应设备的接地直接接通。
On any building, lightning protection equipment is essential. In general, all steel laying in general use, in the practice process, often appear tower connection length deficiency, welding and often appear such as corrosion serious representation, when the bracket is too large interval, drop the simple frame. Other, because the metal roof is not for lightning protection and grounding disposal, is directly connected with the grounding of the trunk line and no corresponding device.
电气施工质量的好坏直接影响到建筑工程的质量,对施工中各项通病进行研究,并找出防治和预控办法是非常重要的,尤其是这些年,电气资料等商场的进一步敞开,施工质量面对的疑问越来越杂乱。
Electrical construction quality directly affects the quality of construction projects, conducts the research to the construction of the problems, and find out the prevention and control measures is very important, especially in these years, further open electrical data stores, the construction quality in the face of increasingly cluttered questions.
