蕉前路A2標段工程施工用電安全技術交底.doc

技術交底內容：
1、 工地用電應由專職的持證電工完成。
2、 電氣設備檢修、停工、臨時停電或下班時，要由設備操作工拉開電源并加鎖。
3、 一切漏電開關、熔斷器、插座均應裝在配電箱內，其容量應與負荷相匹配。
4、 總配電箱除裝有電源總開關及其保護電器外，還應裝有各分路開關，零線要在總配電箱附近重復接地。
5、 所有樓層配電箱應采用金屬箱，箱體、箱門完好無損、有鎖；裝在室外者要有防雨裝置。
6、 導線應絕緣良好、載面符合負載要求；除不超過2M的燈位線和安全電壓的線路外禁止使用花線；架空線路離樓地面3.5M以上，跨越馬路應在6M以上，架空線路應采用電纜，并用硬質管保護。
7、 照明燈位一般應固定安裝在工人工作時碰不著的地方；室外照明應采用防水燈頭，否則應有切實的防雨裝置；民工宿舍采用36伏安全電壓；潮濕場所應用12伏電壓。
8、 熔斷絲脫扣器等保護應與負荷電流配合。
9、 所有電氣設備的金屬外殼均應采用接地（或接零）保護，接地電阻應符合要求；每臺設備應有就近操作的開關和保護；應定期檢查絕緣電阻應在0.5兆歐以上；放置室外的電氣設備應有防雨。
10、 應配備一機一箱一閘一漏電保護開關，并專人專機使用。
11、如工地內設有高壓配電變壓器裝置時
Technical disclosure content:
1, site power should be completed full-time certified electrician.
2, electrical equipment maintenance, downtime, power outages or work, we should pull the power from the equipment operator and locked.
3, all the leakage switches, fuses, sockets should be installed in the power distribution box, load capacity should be matched.
4 In addition to the main distribution box with power switch and protection of electrical things, but also with the shunt switch, the zero line is to be repeated in the main distribution box near the ground.
5, all floors should be of metal box distribution box, box, box door in good condition, with lock; installed in the outdoor unit must have the rain.
6, wires should be insulated well and meet the load requirements contained surface; addition of not more than 2M De lights voltage line and the safety of the Circuit Outside line against the use flower; overhead lines from the floor above the ground 3.5M, cross over the road should be in the 6M, overhead lines cable should be used and protected with a rigid tube.
7, lighting lights should normally be fixed on the workers at work place can no touch; outdoor lighting should be waterproof lamp, rain or devices should be effective; migrant hostels are safe voltage 36 V; damp places applied voltage of 12 volts.
8 Release fuse such protection should match with the load current.
9, all electrical equipment shall be used for grounding the metal shell (or take zero) protection, grounding resistors shall meet the requirements; each device should be close to the switching operation and protection; should regularly check the insulation resistance should be above 0.5 MΩ; place Outdoor electrical equipment shall rain.
10, should be equipped with a machine a case of a leakage of a gate protection switch, and use the hand plane.
11, such as the site is equipped with high-voltage distribution transformers device
