    接地排截麵積小於進線截麵積
    The sectional area of grounding bar is smaller than that of incoming line
    接地排過多的打孔更減小截麵積
    Too many holes are punched in the grounding bar to reduce the cross-sectional area
    接地並線,增加接地阻抗
    Grounding and paralleling to increase grounding impedance
    櫃體安裝底板,框架均未接地
    The bottom plate of the cabinet is installed, and the frame is not grounded
    未采取分層接地的措施
    Layered grounding measures are not taken
    通訊電纜與強電電纜平行敷設
    Communication cable and strong current cable shall be laid in parallel
    通訊線屏蔽層強製接地在絕緣部位
    The shielding layer of communication line is forcibly grounded at the insulating part
    DP總線未正確的固定與屏蔽,CU320模塊的用於固定與屏蔽電纜線的附件缺失。
    DP bus is not properly fixed and shielded, and accessories for fixing and shielding cable of cu320 module are missing.
    編碼器線,裝置通訊線隨意懸空,未作固定,編碼器線亦未作屏蔽。
    The encoder line and the device communication line are suspended at will, not fixed, and the encoder line is not shielded.
    CU320控製單元及接口模塊均未做接地處理。
    Cu320 control unit and interface module are not grounded.
    電氣成套傳動裝置未安裝屏蔽附件,安裝位置偏低,且被線槽阻擋,導致冷卻風道被阻擋,裝置進出線不合理。
    The complete set of electrical transmission device is not installed with shielding accessories. The installation position is low and blocked by trunking, resulting in blocked cooling air duct and unreasonable incoming and outgoing lines of the device.
    櫃體進線位置設計不合理。
    The design of cabinet incoming line position is unreasonable.
    主開關出線采用並線,接觸電阻增大,易發熱。
    The outgoing line of the main switch adopts parallel line, which increases the contact resistance and is easy to heat.
    母排設計結構不合理,進出線混亂,大截麵線存在繞圈布線的現象。
    The busbar design structure is unreasonable, the incoming and outgoing lines are disordered, and the large section line has the phenomenon of circular wiring.
    母排與底板,母排與母排,各相電線之間的絕緣間距不夠。
    The insulation spacing between busbar and baseboard, busbar and busbar, and wires of each phase is insufficient.
    電氣成套
    母排截麵積小於進線截麵積,並且大量打孔,導致有效截麵積進一步減小,從而導致載流量減小。
    The sectional area of busbar is smaller than that of incoming line, and a large number of holes are punched, which further reduces the effective sectional area and leads to the reduction of ampacity.
    母排各路出線未作限流保護,易由小線路短路導致整個線路短路引發線路起火等重大事故。
    The outgoing lines of the busbar are not provided with current limiting protection, which is easy to cause the short circuit of the whole line due to the short circuit of the small line and cause major accidents such as line fire.
    線纜顏色使用不規範。
    The cable color is not standardized.
    強電線路與信號線捆紮在一起行線
    Strong current lines and signal lines shall be bundled together for running
    通訊線屏蔽層懸空,儀表未有效接地
    The shielding layer of communication line is suspended, and the instrument is not effectively grounded
    電纜跨門安裝結構不合理,電線易斷
    The cable cross door installation structure is unreasonable, and the wire is easy to break
    櫃門安裝布線亦應使用線槽,並分類行線
    Wiring for cabinet door installation shall also use trunking and classified wiring
    溫控模塊加熱控製線未用雙絞屏蔽線
    No twisted pair shielded wire is used for the heating control wire of the temperature control module
    電氣成套采用鋁製導軌,並且無接地端子
    Aluminum guide rail is used in the electrical package, and there is no grounding terminal
    通訊線的接地方式不正確,接地效果不明顯
    The grounding mode of communication line is incorrect, and the grounding effect is not obvious
    熱電阻輸入信號線未采用屏蔽電纜,未采用測量精度較高的3線製或4線製接法
    The thermal resistance input signal line does not use shielded cable, and the 3-wire system or 4-wire system connection method with high measurement accuracy is not used
    強電端子正在信號端子的下方,間距很小
    The strong current terminal is under the signal terminal with a small spacing
    強電線與信號線平行敷設在同一線槽內
    Strong wire and signal wire are laid in the same slot in parallel
    濾波器可以不用
    Filter may not be used
    如需使用濾波器應根據負載的實際大小選用濾波器的規格,這裏20A明顯大多了,不起作用
    If you need to use a filter, you should select the filter specification according to the actual size of the load. Here, 20A is obviously too much and does not work
    電氣成套接地端子被用作固定端子
    The complete electrical grounding terminal is used as a fixed terminal
    雙空開為何隻有一相出線
    Why is there only one phase outgoing line for double air switches
