1、停止5次沖擊實(shí)驗(yàn) </p> <p> 請(qǐng)求：每次沖擊實(shí)驗(yàn)均要檢查變壓器有無(wú)異音、異狀。 </p> <p> 新裝的變壓器在帶電投入空載運(yùn)轉(zhuǎn)中，江蘇接地線檢測(cè)生產(chǎn)廠家，會(huì)產(chǎn)生勵(lì)磁涌流，其值可達(dá)6～8倍的額定電流，江蘇接地線檢測(cè)生產(chǎn)廠家。初始勵(lì)磁涌流衰減較快，普通經(jīng)0.5～1s后即可衰減到額定電流值的0.25～0.5倍。但完整衰減的時(shí)間較長(zhǎng)，大容量的變壓器可達(dá)幾十秒。由于勵(lì)磁涌流會(huì)產(chǎn)生很大的電動(dòng)力，江蘇接地線檢測(cè)生產(chǎn)廠家，為了考驗(yàn)變壓器的機(jī)械強(qiáng)度，同時(shí)調(diào)查勵(lì)磁涌流衰減初期能否會(huì)形成繼電維護(hù)安裝誤動(dòng)，故需做沖擊實(shí)驗(yàn)。

電力安全工器具的檢測(cè)是為了在電力系統(tǒng)操作、維護(hù)、檢修、試驗(yàn)、施工等現(xiàn)場(chǎng)作業(yè)中，防止發(fā)生諸如灼傷事件。江蘇接地線檢測(cè)生產(chǎn)廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

2、不要把安全帽歪戴，也不要把帽沿戴在腦后方。否則，會(huì)下降安全帽關(guān)于沖擊的防護(hù)作用。 3、安全帽的下領(lǐng)帶有必要扣在頜下，并系牢，松緊要適度。這樣不致于被勁風(fēng)吹掉，或許是被其他障礙物碰掉，或許由于頭的前后擺動(dòng)，使安全帽墜落。 4、安全帽體頂部除了在帽體內(nèi)部安裝了帽襯外，有的還開(kāi)了小孔通風(fēng)。在使用時(shí)不要為了透氣而隨意再行開(kāi)孔。由于這樣作將會(huì)便帽體的強(qiáng)度下降。</p><p> 超高頻檢測(cè)法 </p> <p>
