      ·外觀查看:檢查是否有移位、掉漆、腐蝕、生銹、變形、變色、異味等情況。這些都可能是某些部件發生故障但是尚未影響到電力輸送的情況,但是安全隱患已經存在了。移位或者柜體傾斜等都不利于低壓抽屜柜的安全使用,要及時矯正;掉漆、變形:可能是機械性外力導致的,是否有彈簧跳出;腐蝕、生銹、變色是否有化學藥劑或者污水腐蝕或者電弧、火苗導致的;異味:大多是由于高溫、著火等原因導致的,這些基本的問題都一定要排查。
      ·Appearance inspection: check whether there is displacement, paint dropping, corrosion, rust, deformation, discoloration, peculiar smell, etc. These may be some parts of the failure, but has not yet affected the power transmission, but the security risks already exist. Displacement or cabinet tilt are not conducive to the safe use of low-pressure drawer cabinet, to be corrected in time; paint, deformation: may be caused by mechanical external force, whether there is spring jump; corrosion, rust, discoloration is caused by chemical agents or sewage corrosion or arc, flame; odor: mostly due to high temperature, fire and other reasons, these basic problems are not obvious We must check.
      ·溫度檢查:溫度是檢驗電力系統故障的常用方法,大多數電路故障都是短路、過壓、過載等原因導致的問題,因此溫度檢查非常重要。
      ·Temperature check: temperature is a common method to check the power system fault, most of the circuit faults are caused by short circuit, overvoltage, overload and other reasons, so temperature check is very important.
      ·雜物檢查:在對低壓抽屜柜更換配件過程中是否有破損配件的殘余軀體,在元器件安裝過程中會殘留大量的線頭、零件以及鐵屑等,其中部分會附著在元器件的表面或里層,因此清掃工作一定要仔細、認真,確保細節干凈。
      ·Debris inspection: whether there are residual bodies of damaged accessories in the process of replacing accessories for low-voltage drawer cabinet, and a large number of thread ends, parts and scrap iron will be left in the process of component installation, some of which will be attached to the surface or inner layer of components, so the cleaning work must be careful and careful to ensure that the details are clean.

      ·機械檢查:斷路器、低壓抽屜進出操作靈活,無卡滯現象。如果有,檢查原因,適當修復。
      ·Mechanical inspection: the circuit breaker and low-voltage drawer are flexible in and out operation, and there is no sticking phenomenon. If so, check the cause and repair properly.
      ·檢查潤滑油:高壓斷路器、低壓抽屜等動觸頭,有適量中性潤滑油脂,查看是否有跑冒滴漏等現象。
      ·Check the lubricating oil: high voltage circuit breaker, low voltage drawer and other moving contacts, there is an appropriate amount of neutral grease, check whether there is leakage and other phenomena.
      ·系統參數查驗:抽屜柜柜內母線制作、安裝檢查,母線相序正確,是否嚴格按照圖紙規劃及安全配電連接標準安裝執行進行安裝操作。這一般在初次安裝后進行檢查,后期不用每次巡檢,在每次更換配件合閘供電之前還需要對更換的配件進行一次電路系統的安裝檢查。
      ·System parameter inspection: check the production and installation of the bus in the drawer cabinet, check whether the phase sequence of the bus is correct, and whether the installation operation is carried out in strict accordance with the drawing planning and safe power distribution connection standard. Generally, the inspection is carried out after the initial installation, and there is no need to inspect every time in the later stage. Before switching on the power supply, the replacement accessories need to be inspected once for the installation of the circuit system.
