                作者:中山市天权电子电讯有限公司 来源:tianquan 发布时间:2019-08-23 浏览:40

                中山弱电工程之弱电系统接地的步骤与方案,对于弱电施工来讲很多都是需要详细的流程与规范的,只有按照规范来进行,这样才可以保障我们中山弱电工程施工的安全进行,下面我们就来详细的了解一下中山弱电工程施工工艺之弱电系统的接地步骤。


                A.一般规定

                1.弱电系统的接地,按用途分有保护性接地和功能性接地。保护性接地分为:防电击接地、防雷接地、防静电接地和防电蚀接地;功能性接地分为:工作接地、逻辑接地、屏蔽接地和信号接地。不同的接地有不同的要求,应按设计决定的接地施工。


                2.需要接地的弱电系统的接地装置应符合下列要求:


                (1)当配管采用镀锌电管时,除设计明确规定处,管子与管子、管子与金属盒子连接后不必跨接,但应遵守下述规定:


                1)管子间采用螺纹连接时,管端螺纹长度不应小于管接头长度的1/2,螺纹表面应光滑、无锈蚀、缺损,在螺纹上应涂以电力复全脂或导电性防腐脂。连接后,其螺纹宜外露2~3扣。


                2)管子间采用带有紧定螺钉的套管连接时,螺钉应拧紧;在振动的场所,紧定螺钉应有防松动措施。


                3)管子与盒子的连接不应采用塑料纳子,应采用导电的金属纳子。


                4)弱电管子内有PE线时,每只接线盒都应和PE线相连。


                (2)当配管采用镀锌电管,设计又规定管子间需要跨接时,应遵守下述规定:


                1)明敷配管不应采用熔焊跨接,应采用设计指定的专用接下来线卡子跨接。


                2)埋地或埋设于混凝土中的电管,不应用线卡跨接,可采取熔焊跨接。


                3)若管内穿有裸软PE铜线时,电管可不跨接。此PE线必须与它所经过的每一只接线盒相连。


                (3)配管采用黑铁管时,若设计不要求跨接,则不必跨接。若要求跨接时,黑铁管之间及黑铁管与接线盒之间可采用圆钢跨接,单面焊接,跨接长度不宜小于跨接圆钢直径的6倍;黑铁管与镀锌桥架之间跨接时,应在黑铁管端部焊一只铜螺栓,用不小于4mm的铜导线与镀锌桥架相连。


                (4)当强弱电都采用PVC管时,为避免干扰,弱电配管应尽量避免与强电配管平行敷设,若必须平行敷设,相隔距离宜大于0.5m。


                (5)当强弱电用线槽敷设时,强弱电线槽宜分开;当需要敷设在同一线槽时,强弱电之间应用金属隔板隔开。


                B.电信设备的接地

                1.为防止外界电压危害人身安全和对设备的损害,抑制电气干扰,保证通信设备正常工作,电信设备的以下部分均应接地:


                (1)直流电源、电信设备的机架、机壳;人站通信电缆的金属护套和屏蔽层。


                (2)交流配电屏、整流器屏等供电设备的外露导电部分 。


                (3)直流配电屏的外露部分 。


                (4)交直流两用电信设备的机架、机框内与机架、机框不绝缘的供电整流盘的外露导电部分。


                (5)电缆、架空线路及有关需要接地的部分,如放电器、避雷器、保护间隙等。


                2.当低压配电系统采取TN制式供电,电信设备若要求严格限制工频交流对其的干扰,且电信设备不易做到与站内各种金黄色属构件绝缘时,应采用TN-S制式;当对干扰要求不太严格时,可采用TN-C制式;当电信设备的泄漏电流在10mA及以上时,应采用TN-S制式。


                3.配电屏、整流器屏等外露导电部分,当加固装置将其与机架、机框在电气上已连通时,仍需与PE线或PEN线相连。


                4.当采取IT制式供电,电信设备的泄漏电流在10mA以上时,为了避免保护设备误动作,可采取双线圈变压器供电,其一次侧接入IT制式,二次侧若以TN制式供电,此时供电设备的接地与TN制式相同。


                5.电信设备的工作接地,一般要求单独设置,亦可与建筑物内变压器的工作接地共用一个接地装置。但必须通过绝缘的专用接地线与接地装置相连。


                6.电信设备采用共同接地装置时,其接地电阻应不大于1Ω,宜用两根截面积不小于25mm2的铜芯绝缘线穿管敷设到共同接地极上。当采用基础钢筋作为共同接极时,连接处应有铜铁过渡接头。


                C.电子设备的接地

                1.电子设备的信号接地、逻辑接地、功率接地、屏蔽接地和保护接地等,一般合用一个接地极,其接地电阻不大于4Ω;当电子设备的接地与工频交流接地、防雷接地合用一个接地极时,其接地电阻不大于1Ω。屏蔽接地如单独设置,则其接地电阻一般为30Ω。


                2.对抗干扰能力差的电子设备,其接地应和防雷接地分开,两者相互距离宜在20m以上,对抗干扰能力较强的电子设备,两者距离可酌情减少,但不宜超过5m。


                当电子设备接地和防雷接地采用共同接地装置时,为了避免雷击时遭受反击和保证设备的安全,应采用埋地铠装电缆供电。


                3.电缆屏蔽层必须接地,为避免产生干扰电流,对信号电缆和1MHZ及以下低频电缆应一点接地;对1MHZ以上电缆,为保证屏蔽层为地电位,应采取多点接地。


                4.为了避免环路电流、瞬时电流的影响,辐射式接地系统应采用一点接地;为消除各接地点的电位差,避免彼此之间产生干扰,环式接地系统应采用等电位连接;对混合式接地系统,在电子设备内部采用辐射式接地,在电子设备外部采用环式接地系统。


                5.接地环母线的截面,当电子设备频率在1MHZ以上时,用铜箔120mm×0.35mm;在1MHZ以下时,用铜箔mm×0.35mm。


                6.电子设备的接地极宜采用地下水平敷设,做成耙形或星形。


                D.数据处理设备的接地

                1.数据处理设备的接地电阻一般为4Ω,当与交流工频接地和防雷接地合用时,接地电阻为1Ω。


                2.对于泄漏电流10mA以上的数据处理设备,其主机室内的金属体应相互连接成一体,连接线可采用6mm2的铜导线或25mm×4mm 镀锌扁钢,并进行接地,接地电阻不大于4Ω。


                3.为了减少趋肤效应和通道阻抗,直流工作接地的引下线应采遥多芯铜导线,截面不宜小于35 mm2,当需要改善信号的工作条件时,宜采用多股铜绞线。


                4.直流工作接地与交流工作接地如不采用共同接地时,两者之间的电差不应超过0.5V,以免产生干扰。


                5.输入信号的电缆穿钢管敷设,或敷设在带金属盖板的金属桥架内,钢管及桥架均应接地。


                E.电声、电视系统的接地

                电声、电视系统的接地电阻一般为4Ω,工业电视系统如设备容量≤0.5kVA


                时,接地电阻可不大于10Ω。架设在建筑物顶部的天线金属底座必须与建筑物顶部的避雷网相连,构成避雷系统,通过至少在不同方向的两根引下线或建筑物内的主钢筋进行接地。


                为避免由于接地电位差造成交流杂散波的干扰,闭路电视和工业电视必须采用一点接地。


                电视系统的传输电缆穿金属管敷设时,金属管要接地,用以防止干扰。


                F.接地极和接地线的安装

                1.强弱电采用联合接地极时,接地电阻必须小于1Ω。


                2.采用联合接地极时,弱电接地引出线和强电接地引出线不能从同一点引出,两者要相距3m以上。


                3.对于抗干扰要求高的设备,例如电脑、消防控制室的接地干线应用截面积不小于25 mm2绝缘铜导线两根或固定在绝缘子上的接地排,避免和强电接地线相通。    


                希望我们可以更加详细的去了解一下弱电相关的知识,丰富自己的技术水平。      http://www.tianquandz.com/
