電纜橋架接地施工要求

  電纜橋架的跨接材料應按設計要求施工。若設計沒有具體要求,應按以下要求。
  The bridge material of the cable bridge shall be constructed according to the design requirement. If design does not have specific requirement, should press the following request.
  a、鍍鋅電纜橋架之間可利用鍍鋅連接板作為跨接線,把橋架連成一體,在連接板兩端的兩只連接螺栓上加鍍鋅彈簧墊圈。電纜橋架
  A connection can use galvanized, galvanized cable tray plate as a jumper, put the bridge together as a whole, on two connecting bolt at the ends of the connecting plate and galvanized spring washer.
  b、涂漆和噴塑及噴涂其它絕緣物的橋架,應采用軟銅線跨接。 跨接用的螺栓應鍍鋅,跨接導線端子與橋架接觸處,既要絕緣涂層,還要涂防銹導電膏?;蛭兄圃鞆S在橋架上焊銅墊圈,保證電纜橋架之間跨接可靠。
  The bridge of b, painting and spraying and spraying other insulation shall be made of flexible copper wire. The bolted bolts shall be galvanized, and the contact between the terminals and the bridge shall be removed, and the insulating coating shall be cleaned and the rust conductive paste shall be applied. Or entrust the manufacturer to weld the copper washer on the bridge and guarantee the reliability of the cable bridge.
  c、橋架經(jīng)過建筑物變形縫和直線段超過30m,設補償裝置處,橋架間斷兩端應用軟銅導線跨接,并留有伸縮余量。對于振動場所,在接地部位的連接處應裝置彈簧圈。
  C, the bridge is over 30 meters in the shape of the deformation of the building and the line segment, and the compensator is located, and the bridge is intersecting with the flexible copper conductor at the end of the bridge, and there is a retractable residual amount. For vibrations, the spring coil should be installed at the connection of the ground.
  橋架系統(tǒng)應具有可靠的電氣連接,電纜橋架從始端到終端,少有一處與接地干線可靠連接。沿橋架全長另敷設接地干線時,每段(包括非直線段)橋架應少有一點與接地干線可靠連接。
  The bridge system should have reliable electrical connection, the cable bridge is from the beginning to the terminal, at least one is connected to the ground main. Each section (including non-linear segment) bridge should have at least one reliable connection to the grounding line when the bridge is all over the ground.
  鍍鋅橋架之間可利用鍍鋅連接板作為跨接線,把橋架連成一體。在連接板兩端的兩只連接螺栓上加鍍鋅彈簧墊圈,橋架之間用不小于4mm2軟銅線進行跨接,再將橋架與接地線相連,形成電氣通路。橋架整體與接地干線應有不少于兩處的連接。
  Zinc-plated bridge can be used to connect the bridge with the galvanized connection plate. On two connecting bolt at the ends of the connecting plate and galvanized spring washer, bridge between was not less than 4 soft copper wire jumper, then bridge connected to the grounding wire, electrical pathway. There should be no less than two connections between the total and ground trunk of the bridge.
  若設計要求把橋架作為接地干線的一部分,則要求遵守電纜橋架安裝規(guī)范在接頭處的連接電阻不應大于0.00033Ω。若利用橋架連接板達不到這個要求,即使是鍍鋅橋架,也應用符合設計要求的軟銅導線跨接。
  The bridge if design requirements as part of the grounding line, is for the cable tray installation specification in connection joint should not be greater than 0.00033 Ω resistance. If the bridge board is not able to reach this requirement, even the galvanized bridge is applied to the flexible copper wire that meets the design requirements.
