?You will sympathize with me in our mutual loss. Probably, we he seen the last of our old friend Tim; he departed from his well scratched pole about two weeks ago, and is now on the road as an important item in ‘The Most Colossal Show Ever Known.’ He had grown so large, and his appetite for strong drink had increased to 108 such an alarming extent, that the attending darkies lost confidence in their ability to handle him. During his later days at the Lake, he appeared to he but one idea, and that related to opportunities for intoxication. Whenever his pen door opened, no matter for what pure, he would make a rush for whoever came in, and demand to be led to the bar-room, and, if disappointed, would make a most furious demonstration.

阻燃電纜,是指在規(guī)定試驗條件下,試樣被,在撤去試驗火源后,火焰的蔓延僅在限定范圍內(nèi),殘羊殘灼在限定時間內(nèi)能自行熄滅的電纜。根本特性是:在火災(zāi)情況下有可能被燒壞而不能運行,但可火勢的蔓延。通俗地講,電線萬一失火,能夠把在局部范圍內(nèi),不產(chǎn)生蔓延,保住其他的各種設(shè)備,避免造成更大的損失。 阻燃電纜的含義:在規(guī)定試驗條件下,試樣被,在撤去火源后,火焰在試樣上的蔓延僅在限定范圍內(nèi)并且自行熄滅的特性,即具有或延緩火焰發(fā)生或蔓延的能力。

In course of time, Tim became quite a bear, altogether too large for a bar-room pet, and was removed to a specially prepared pen and chained to a pole with a platform rest at the top. 99 The change for Tim was not a success. He spent his time in running around and climbing up and down his pole, all the time whining, pleading, and scolding; he grew thin, and looked and acted as though he regarded life as a failure. Occasionally, a friend, pitying his unhappy condition, would unchain him and lead him to his old haunt. In fact, it was nearly imsible to lead him in any other direction. As soon as released from his pole he would start for the bar-room, dragging his friend with him, nor would he stop until he reached his forite room, when, standing up with his hands on the counter, he would mumble out in his most inligible bear-language a peremptory demand for a drink. Sometimes he was indulged to an extent which would enable him to catch a glimpse of his lost paradise, but usually he was returned to his pen after hing dised 100 of only enough of his forite beverage to give him an appetite for more.

(2) MY礦用電纜地線芯,煤礦的供電系統(tǒng)的中性點不是直接接地的,電纜的地線芯直流電阻必須滿足有關(guān)規(guī)程規(guī)定,6KV供電系統(tǒng)中保護裝置的應(yīng)用不如低壓系統(tǒng)的普遍,電纜單相接地之后,往往不能及時處理,會引起另一向在不同區(qū)域?qū)Φ負舸?,造成兩相通過地線短路。因此,要求地線芯有足夠截面,地線芯與動力線芯之間存在電容和互感,在實際應(yīng)用中,地線芯必須良好接地,否則會引起嚴重的人身傷亡。
(3)MYPTJ礦用電纜監(jiān)視線(層),監(jiān)視線的主要功能是監(jiān)視地線的連續(xù)性,經(jīng)過結(jié)構(gòu)設(shè)計上的演繹之后,監(jiān)視線均布電纜軸心的同心圓周上,它又兼有監(jiān)視外界破壞物體侵入的作用。
(4)MC礦用電纜外護套,由于科學(xué)技術(shù)的進步,使得彩色鮮艷的外護套工業(yè)化生產(chǎn)成為現(xiàn)實,井下電線電纜為便于區(qū)分電壓等級,規(guī)定6KV電纜外護層為紅色,1140V為黃色,660V及以下為黑色,這既便于區(qū)分不同電壓等級的電纜,又美化了煤礦井下的生產(chǎn)環(huán)境,至于露天礦用電纜,目前尚不能使用彩色護套,這是由于白色無機填加劑,在日光暴露初MCPJR-0.69/1.14 3×50+1×25+2×25期,對光的折射,聚合物降解速度轉(zhuǎn)慢,經(jīng)過一段時間之后,氧化反應(yīng)終破壞了聚合物分子鏈,導(dǎo)致護套表面粉化和裂紋,所以,目前的露天電纜外護套仍以黑色為主。
礦用阻燃橡套電纜特點:
1:移動頻繁。工作中需要經(jīng)常移動,要求護套有較好的耐磨性。電鉆電纜除經(jīng)常搬運電鉆而拖動,要求一定的抗拉力。采掘機電纜在工作中不斷在機組上卷放、收繞井在地面上拖動。MCPJR-0.69/1.14 3×50+1×25+2×25
2:經(jīng)常彎曲和扭轉(zhuǎn).以電鉆電纜和采掘機電纜為嚴重。特別是電纜與電鉆或采掘機連接出,是受到彎曲、扭轉(zhuǎn)力以及拉力嚴重的部位。要求電纜在很好的柔軟性和耐多次彎曲、扭轉(zhuǎn)性。
3:機械外力破壞。菜采區(qū)工作的電纜,易被掉下的礦石或是巖石的沖砸而損壞,或被大的礦石及其他裝備(如礦車)、材料壓住,壓扁電纜而引起電氣短路。在礦井電纜事故中,比率大。MCPJR-0.69/1.14 3×50+1×25+2×25
4:不易引起燃燒。煤礦及其他礦井有瓦斯氣,易爆易燃。要求電纜內(nèi)絕緣受損后不易引起火花而引燃;電纜不延燃,以免擴大事故范圍。
5:有較好的電氣性能和安全保護系統(tǒng)。礦井中極為潮濕,流水多,電纜又與工人直接接觸;因此要求電纜有足夠的電氣強度和良好的絕緣性能。當(dāng)外力機械破壞而產(chǎn)生電氣短路事故時,應(yīng)有靈敏可靠的斷電保護系統(tǒng)及時切斷電源;因此優(yōu)先發(fā)展屏蔽型電纜品種。MCPJR-0.69/1.14 3×50+1×25+2×25
6:井下搬運條件差,要求電纜輕、小、使用方便,便于檢修。
7:露天礦用的高壓電纜要求耐大氣候老化。
