架線(xian)(xian)(xian)(xian)防震錘是(shi)(shi)電(dian)力金具(ju)中(zhong)的(de)一種用(yong)于電(dian)線(xian)(xian)(xian)(xian)電(dian)纜(lan)上(shang)(shang)的(de)裝置(zhi),它通常(chang)安(an)(an)裝在室外架空電(dian)力線(xian)(xian)(xian)(xian)路上(shang)(shang),用(yong)于防止線(xian)(xian)(xian)(xian)路因(yin)為風力的(de)原因(yin)而承(cheng)受不住(zhu)而斷開,起(qi)保(bao)護線(xian)(xian)(xian)(xian)纜(lan)的(de)作用(yong),架線(xian)(xian)(xian)(xian)防震錘既然是(shi)(shi)安(an)(an)裝在電(dian)路線(xian)(xian)(xian)(xian)路上(shang)(shang),防止風吹電(dian)線(xian)(xian)(xian)(xian)而張力過大讓電(dian)路發生斷裂情(qing)況的(de),那對于防震錘的(de)安(an)(an)裝也是(shi)(shi)有嚴格規定的(de),其中(zhong)每(mei)條線(xian)(xian)(xian)(xian)路上(shang)(shang)安(an)(an)裝多少個防震錘?每(mei)個架線(xian)(xian)(xian)(xian)防震錘的(de)安(an)(an)裝距離是(shi)(shi)多少?如何計算?相信多數(shu)朋友是(shi)(shi)不想知道的(de)吧,帶著(zhu)這(zhe)些問題,跟(gen)小編走進解(jie)說:
對耐張線(xian)夾來說,所謂(wei)架線(xian)防震錘的安裝距離指的是從線(xian)夾穿釘孔(kong)到防震錘夾板(ban)中點之距離;
對(dui)懸垂線夾(jia)來說,所謂架線防震錘的安(an)裝距離指的是從線夾(jia)中點到防震錘夾(jia)板中點之(zhi)距離;
防震(zhen)錘的安(an)裝距離(S)可由(you)下式(shi)來進行計算(suan):
距離(li)(S)= 10的-3次(ci)方(m) × 0.98 d√ Tmin/W (0.75 + 1/1 + 0.125 √Tm ax/Tmin)
式中:
d - 架空線的直徑(cm)
Tm ax - 較低溫度時架空線的張力(kg)
Tmin - 較高溫度時架空線的張力(kg)
W - 架空線的自重(kg/m)
架線(xian)防(fang)震(zhen)錘(chui)是讓線(xian)纜(lan)在運行(xing)時(shi)因各種原因而產生震(zhen)動(dong)的降(jiang)低或是去除,它的確(que)定(ding)安裝距(ju)離是防(fang)震(zhen)錘(chui)工作在較(jiao)小和較(jiao)大(da)、任意的半波長(chang)振動(dong)限度值條件(jian)下,大(da)致都(dou)相似,使防(fang)震(zhen)錘(chui)都(dou)不進入距(ju)桿塔較(jiao)近的振動(dong)波節內。
