多極管式滑觸線接通電源試行時應注意的幾點事項
多極管式滑觸線接通電源試行時應注意的幾點事項：
Multipolar tubular sliding contact line switching power supply for some matters that should be paid attention to:
1、通電前復查全線安裝情況，確認無誤后，調試人員可進行入操作崗位，其他人員應撤離現場或進入安全地區。
1, review all prior to power installation, after confirmed, debugging personnel can be carried out into the operating post, other personnel should be evacuated from the scene or into the security area.
2、接通電源后，不急于開動起重機，觀察靜態通電是否正常，然后啟動小車電機，試運行兩分種，再啟動大天車電機，以低速行駛，沿全線觀察，應特別注意運動部分與支架、水泥柱等有無碰擦的可能性，若發現下述情況，應立即糾正：
2, after turning on the power supply, in no hurry to start the crane, observe whether the static electricity is normal, then start the car motor, two kinds of commissioning, to start the big crown motors, running at low speed, along the broad observation, should pay special attention to moving parts and the possibility of stents, such as concrete with and without scratches, if discover the following situation, should immediay correct:
a、導管有較大異動，應調整導管或修正撥叉。
A have a great move, catheters, catheter or fixed fork should be adjusted
b、導電器運行時有異常聲響，應檢查導軌連接點是否平坦。
B, guide electrical operation there is abnormal sound, should check flat guide rail connection point.
