低壓抽屜柜雖然不是故障高發(fā)設(shè)備,但是日常巡檢必不可少,而且個別時期的故障檢查以及定期巡檢都需要得到重視。那么低壓抽屜柜在檢查時要注意哪些問題呢?MNS低壓抽屜柜的巡檢需要注意的問題還不少,在日常巡檢和故障檢修過程中,不可單一的排除故障,更換配件,每次都盡可能的做到全 方位檢查。
Although the low-voltage drawer cabinet is not a high-risk equipment, but daily inspection is essential, and individual period of fault inspection and regular inspection need to be paid attention to. So what problems should we pay attention to when checking the low-voltage drawer cabinet? The inspection of MNS low-voltage drawer cabinet needs to pay attention to many problems. In the process of daily inspection and troubleshooting, it is not only necessary to remove the fault and replace the accessories, but also try to do all-round inspection every time.
低壓抽屜柜日常檢查的工作項目包括:
Daily inspection items of low voltage drawer cabinet include:
1·配電柜及柜中的電器元件的名稱、標志、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)場情況是否相符,固定是否牢靠。
1. Whether the name, mark and number of the power distribution cabinet and the electrical components in the cabinet are clear and correct, whether the positions of all the operation handles, buttons and keys on the panel are consistent with the site conditions, and whether the fixation is firm.
2·配電柜上表示“合”、“分”的信號燈及其它信號指示是否正確。
2. Whether the signal lights and other signals indicating "on" and "off" on the power distribution cabinet 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. Whether the contacts of disconnector, circuit breaker, fuse and mutual inductor are reliable, and whether there is overheating and discoloration.
4·模擬板與現(xiàn)場電氣設(shè)備的運行狀態(tài)是否對應(yīng)。
4. Whether the operation status of the simulation board is corresponding to that of the field electrical equipment.
5·儀表或表盤玻璃是否松動,儀表指示是否正確。
5. Whether the instrument or dial glass is loose and whether the instrument indication is correct.
6·配電室內(nèi)的照明燈具是否完好,照度是否合適。
6. Whether the lighting in the distribution room is in good condition and the illumination is appropriate.
7·認真記錄巡視檢查中發(fā)現(xiàn)的問題,以及現(xiàn)場處理情況。
7. Carefully record the problems found in the inspection and the on-site treatment.
檢查MNS低壓抽屜柜要注意以下問題:
Pay attention to the following problems when checking MNS low-voltage drawer cabinet:
1·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(fā)生故障但是尚未影響到電力輸送的情況,但是隱患已經(jīng)存在了。移位或者柜體傾斜等都不利于低壓抽屜柜的使用,要及時矯正;掉漆、變形:可能是機械性外力導(dǎo)致的,是否有彈簧跳出;腐蝕、生銹、變色是否有化學(xué)藥劑或者污水腐蝕或者電弧、火苗導(dǎo)致的;異味:大多是由于高溫、著火等原因?qū)е碌?,這些基本的問題都一定要排查。
1. 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.
2·溫度檢查:溫度是檢驗電力系統(tǒng)故障的常用方法,大多數(shù)電路故障都是短路、過壓、過載等原因?qū)е碌膯栴},因此溫度檢查非常重要。
2. Temperature inspection: temperature is a common method to inspect power system faults. Most circuit faults are caused by short circuit, overvoltage, overload and other reasons, so temperature inspection is very important.
3·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(jié)干凈。
3. 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.
4·機械檢查:斷路器、低壓抽屜進出操作靈活,無卡滯現(xiàn)象。如果有,檢查原因,適當修復(fù)。
4. Mechanical inspection: the circuit breaker and low-voltage drawer can be operated flexibly without jamming. If so, check the cause and repair properly.
          電氣成套
5·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(xiàn)象。
5. Check the lubricating oil: high voltage circuit breaker, low voltage drawer and other moving contacts, there is an appropriate amount of neutral lubricating grease, check whether there is leakage and other phenomena.
6·系統(tǒng)參數(shù)查驗:抽屜柜柜內(nèi)母線制作、安裝檢查,母線相序正確,是否嚴格按照圖紙規(guī)劃及配電連接標準安裝執(zhí)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(tǒng)的安裝檢查。
6. System parameter inspection: check the production and installation of the busbar in the drawer cabinet, check whether the busbar phase sequence 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.
在MNS低壓抽屜柜使用過程中,一般的日常巡檢就是這么多的工作,但這是建立在初次合格安裝的基礎(chǔ)上,如果是初次安裝需要檢查的東西就太多了。
In the use process of MNS low-voltage drawer cabinet, the general daily inspection is so much work, but it is based on the first safe and qualified installation. If it is the first installation, there are too many things to check.
