為了保證對用電場所的正常供電，對配電屏上的儀表和電器應(yīng)經(jīng)常進行檢查和維護，并做好記錄，以便隨時分析運行及用電情況，及時發(fā)現(xiàn)問題和隱患。
In order to ensure the normal power supply to the electric field, the instruments and electrical appliances on the distribution panel shall be regularly inspected and maintained, and records shall be made, so as to analyze the operation and power consumption at any time, find problems and eliminate hidden dangers in time.
對運行中的低壓開關(guān)柜，通常應(yīng)檢查以下內(nèi)容：
For the low-voltage switchgear in operation, the following contents shall be checked:
(1)配電屏及屏上的電氣元件的名稱、標(biāo)志、編號等是否清楚、正確，盤上所有的操作把手、按鈕和按鍵等的位置與現(xiàn)場實際情況是否相符，固定是否牢靠，操作是否靈活。
(1) Whether the name, mark and number of the distribution panel and the electrical components on the panel are clear and correct, whether the positions of all operation handles, buttons and keys on the panel are consistent with the actual situation on site, whether the fixation is firm and whether the operation is flexible.
(2)配電屏上表示“合”、“分”等信號燈和其他信號指示是否正確。
(2) Whether the "on", "off" and other signal indicators and other signal indications on the distribution panel are correct.
(3)隔離開關(guān)、斷路器、熔斷器和互感器等的觸點是否牢靠，有無過熱、變色現(xiàn)象。
(3) Check whether the contacts of disconnectors, circuit breakers, fuses and mutual inductors are reliable and whether there is overheating and discoloration.
(4)二次回路導(dǎo)線的絕緣是否破損、老化。
(4) Whether the insulation of secondary circuit conductor is damaged and aged.
(5)配電屏上標(biāo)有操作模擬板時，模擬板與現(xiàn)場電氣設(shè)備的運行狀態(tài)是否對應(yīng)。
(5) When the operation simulation board is marked on the distribution panel, whether the operation status of the simulation board corresponds to that of the on-site electrical equipment.
(6)儀表或表盤玻璃是否松動，儀表指示是否正確。
(6) Whether the instrument or dial glass is loose and whether the instrument indication is correct.
(7)配電室內(nèi)的照明燈具是否完好，照度是否明亮均勻，觀察儀表時有無眩光。
(7) Whether the lighting fixtures in the distribution room are in good condition, whether the illumination is bright and uniform, and whether there is glare when observing the instrument.
(8)巡視檢查中發(fā)現(xiàn)的問題應(yīng)及時處理，并記錄。
(8) Problems found during patrol inspection shall be handled in time and recorded.
低壓帶電工作要求
Safety requirements for low voltage live working
低壓帶電工作應(yīng)設(shè)專人監(jiān)護，使用有絕緣柄的工具，工作時站在干燥的絕緣物上，戴絕緣手套和帽，穿長袖衣，嚴(yán)禁使用銼刀、金屬尺和帶有金屬物的毛刷、毛撣等工具。
For low-voltage live work, special personnel shall be assigned to monitor and use tools with insulating handle. When working, stand on dry insulation, wear insulating gloves, safety helmets and long sleeved clothes. It is strictly prohibited to use files, metal rulers, brushes and Dusters with metal objects.
在高低壓同桿架設(shè)的低壓帶電線路上工作時，應(yīng)先檢查與高壓線的距離，采取防止誤碰高壓帶電設(shè)備的措施。
When working on the low-voltage live line erected on the same pole of high and low voltage, first check the distance from the high-voltage line and take measures to prevent accidental collision with the high-voltage live equipment.
