高壓開關(guān)柜是高低壓成套設(shè)備中不可缺少的一部分,在電力系統(tǒng)中起著重要的作用,那么,在日常使用時我們高低壓電氣成套設(shè)備需要做哪些維護工作呢?
High voltage switchgear is an indispensable part of high-voltage and low-voltage complete sets of equipment, which plays an important role in the power system. Then, what maintenance work should we do for high-voltage and low-voltage electrical complete sets of equipment in daily use?
(一)檢查、清掃開關(guān)柜,柜體清潔無灰塵。柜面觀察窗清潔透明。
(1) Check and clean the switch cabinet. The cabinet is clean without dust. The observation window on the cabinet is clean and transparent.
(二)高低壓成套設(shè)備柜面元件安裝端正,接線牢固,電度表、高壓帶電指示裝置、繼電器及信號燈工作正常,符合相關(guān)規(guī)定。檢查開關(guān)位置指示信號燈指示正確。
(2) The cabinet components of high and low voltage complete sets of equipment are installed correctly, the wiring is firm, the watt hour meter, high voltage live indicator, relay and signal lamp work normally, and meet the relevant regulations. Check that the switch position indicator is correct.
(三)檢查開關(guān)柜密封良好,門鎖齊全,機械和電氣帶電閉鎖裝置作用可靠,在有電情況下不能打開柜門。手車位置檢測行程開關(guān)作用良好,能正確反映手車位置。開關(guān)機械位置閉鎖裝置作用良好。高低壓電氣成套設(shè)備檢查二次回路連接牢固,接線正確。
(3) Check that the switch cabinet is well sealed, the door locks are complete, the mechanical and electrical live locking devices are reliable, and the cabinet door cannot be opened when there is electricity. The function of the travel switch for handcart position detection is good, which can correctly reflect the position of handcart. The mechanical position locking device works well. Check whether the secondary circuit of high and low voltage electrical equipment is firmly connected and the wiring is correct.
(四)拉出手車,高低壓電氣成套設(shè)備檢查開關(guān)柜后部帶電防護檔板作用良好,開關(guān)手車拉出后能自動復位。
(4) Pull out the handcart, check the high and low voltage electrical equipment, and check that the electrified protection baffle at the back of the switch cabinet works well, and the switch handcart can reset automatically after pulling out.
(五)檢查高低壓成套設(shè)備柜體接地良好,手車接地軌道接觸良好,表面無銹蝕現(xiàn)象。手車推拉應(yīng)輕松靈活,到位后能自動閉鎖定位,無卡滯現(xiàn)象。
(5) Check that the cabinet of high and low voltage complete equipment is well grounded, the grounding rail of handcart is in good contact, and the surface is free of corrosion. The push and pull of the handcart should be easy and flexible, and it can automatically lock and locate when it is in place without jamming.
(六)電流互感器及過電壓吸收裝置。用抹布擦拭互感器及過電壓吸收裝置表面,高低壓電氣成套設(shè)備檢查一次接線緊固情況。檢查互感器二次端子和鐵芯接地良好。
(6) Current transformer and overvoltage absorption device. Wipe the surface of transformer and over-voltage absorption device with cloth, and check the fastening of primary wiring of high and low voltage electrical equipment. Check whether the secondary terminal and iron core of the transformer are well grounded.
