              在排查濟南液壓升降機電氣系統故障過程中,經;赜龅骄路看似是接通的但平臺就是不能正常工作的情況,對于缺少經驗的維修人員來說,排查這種故障十分困難。其實這種情況大多數是因為電氣系統產生的虛電干擾了故障的判斷。In the investigation of Ji'nan hydraulic elevator electrical system fault process, often encounter seemingly line is connected to the platform but is not working properly, for lack of experience in the maintenance staff, the investigation of this fault is very difficult. In fact, most of this situation is due to the electrical system generated virtual disturbance of the fault of the judge.

              1.對于需防護的液壓平臺電氣系統部件,檢查時應觀察電氣元器件的密封防水部位是否被損壞。對于暴露在外界空氣中的電氣連接部分,要經常檢查是否存在生銹腐蝕現象。對于已經被腐蝕的電線接頭,要及時的做除銹處理或者更換新元件。For the protection of the hydraulic system components of the electrical system, check the electrical components should be observed when the seal waterproof parts are damaged. For exposure to the outside air in the electrical connection part, should always check whether the presence of rust corrosion. The wire connector has been corrosion, to timely do rust removal or replacement of components.

              2.對于灰塵較多的環境下工作的平臺要經常對電器元件進行除塵處理防止灰塵進入元件內部。For more dust in the environment of the platform to often carry out the electrical components of the dust removal process to prevent dust into the internal components.

              3.對于工作時振動過大的工程機械要經常對其電氣線路的連接情況進行檢查看是否存在電線接頭松動的情況。For the work of the vibration is too large construction machinery to often the connection of its electrical lines to check to see if there is a loose wire connection.

              4.對于接觸器、斷路器等開關元器件的觸點要經常做維護保養以使元件觸電接觸面保持平整。For contactor, circuit breakers and other switch components of the contact should always do maintenance in order to make the element electric shock contact surface to maintain level.

              5.對于因加油或者設備維修而產生的油污,要及時清除干凈放置油污對電氣線路產生腐蝕性污染。For oil pollution caused by gas or equipment maintenance, timely removal of oil pollution on the electrical lines to produce corrosive pollution.

              所謂虛電就是空載測量時電壓正常而加載后就會出現失壓的現象。根據我們的維修經驗虛電的產生大多是由線路接觸不良而引起的。為避免該類故障產生應采取以上措施。The so-called virtual power is no load measurement when the voltage is normal and will appear after loading the phenomenon of pressure. According to our maintenance experience, the generation of virtual electricity is mostly caused by poor line contact. In order to avoid this kind of failure, we should take the above measures.
