style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85, 85); background-color: rgb(255, 255, 255);"><span style="font-size: 16px;">試驗(yàn)遮欄應(yīng)使用絕緣的網(wǎng)狀遮欄或木質(zhì)遮欄。用繩子時(shí)需用上下兩條。遮欄的安裝，應(yīng)考慮到不妨礙運(yùn)行人員巡檢查和處理故障時(shí)的行走。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85,

16px;">6、試驗(yàn)用接地線應(yīng)盡量不穿過通道，以免被人絆斷，否則設(shè)兩根接地線，分別在兩處接地。在試驗(yàn)地點(diǎn)設(shè)有可靠的接地點(diǎn)時(shí)，除接地外，還應(yīng)接零。接地線應(yīng)采用有足夠截面的多股裸銅線。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85, 85); background-color: rgb(255, 255,

margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85, 85); background-color: rgb(255, 255, 255);"><span style="font-size: 16px;">8、試驗(yàn)高壓線應(yīng)盡量短，試驗(yàn)前必須檢查其機(jī)械強(qiáng)度及絕緣強(qiáng)度。試驗(yàn)設(shè)備布置和高壓試驗(yàn)線的敷設(shè)應(yīng)考慮在其折斷掉下來時(shí)不危及人身安全。室外刮風(fēng)天氣應(yīng)考慮風(fēng)向。試驗(yàn)人員應(yīng)處于上風(fēng)處。盡量避免在樓梯走廊或過道通過高壓試驗(yàn)線。高壓試驗(yàn)線的敷設(shè)也不應(yīng)阻塞通往運(yùn)行設(shè)備的通道。如需經(jīng)過通道應(yīng)有足夠的人員警戒，以保證在需要時(shí)能立即停止試驗(yàn)，讓出通道。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85, 85); background-color: rgb(255, 255, 255);"><span style="font-size: 16px;">9、試驗(yàn)電源的刀閘應(yīng)裝在試驗(yàn)現(xiàn)場，不準(zhǔn)用遠(yuǎn)離試驗(yàn)現(xiàn)場的刀閘。刀閘應(yīng)能明顯看出斷開位置。為防止誤合，在刀口可加絕緣墊。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85, 85); background-color: rgb(255, 255, 255);"><span style="font-size: 16px;">試驗(yàn)時(shí)須拆下運(yùn)行人員裝設(shè)的地線時(shí)，只有在試驗(yàn)接線完成后，準(zhǔn)備加電壓前，才能拆下試驗(yàn)地線，試先后該相地線即應(yīng)重新裝好。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; line-height: 26px; font-family: 宋體; color: rgb(85, 85,
