滑觸線電源進線與信號燈的安裝

1、電源進線與信號燈的安裝。用一根40mmx4mm的鍍鋅扁鋼彎制而成的。彎制的扁鋼焊在滑觸線上，焊接前應先鉆好孔，在孔周圍搪好錫以使接線端子與扁鋼的接觸良好。
1, the power supply into line with the installation of lights. With a 40 mmx4mm galvanized flat steel bending. Bending of the flat steel welded on the sliding contact line, should be good drill hole before welding, around the hole boring good tin to make terminal blocks have a good contact with the flat.
2、當滑觸線長度超過50m時，為適應溫度變化而引起滑觸線的伸縮，也應裝設補償裝置。
2, when the sliding contact line length of more than 50 m, in order to adapt to the temperature change caused by the expansion of sliding contact line, should also be installed compensation device.
當滑觸線的線路較長，電壓降超過允許值時，滑觸線上應加裝輔助鋁母排，每隔12m用M10螺栓螺母連接一次，連接處應搪錫。
When the line of the sliding contact line is longer, the voltage drop exceeds allowable values, sliding contact line should be equipped with auxiliary aluminum busbar, every 12 m with M10 bolt and nut connection time, technicians to joint should be tin.
3、滑觸線跨越建筑物伸縮縫時，滑觸線應裝有膨脹補償措施?；|線在伸縮縫的間隙，一般為10-20mm。間隙兩側(cè)的滑觸線端頭應加工圓滑，接觸面安裝在一水平面上，其兩端高差不能大于1mm。在靠近伸縮縫的兩側(cè)滑觸線應加裝支架，從間隙中心線到支架中心線的距離不應超過150mm。
 

3, sliding contact line across the building expansion joints, sliding contact line is supposed to contain inflation compensation measures. Sliding contact line on the expansion joint clearance, generally for 10 to 20 mm. Clearance on both sides of the sliding contact line end should be processing, smooth interface is installed in a horizontal plane, the elevation difference is not greater than 1 mm at both ends. Near the expansion joint of two side sliding contact line should be equipped with stents, the distance from the center line of the clearance to support the centerline should not exceed 150 mm.
