　　How to operate and maintain the complete 10kV distribution system of Shandong Electric? Practical Process Collection

　　在山東電氣成套設(shè)備的配置中，變壓器作為電力轉(zhuǎn)換的核心部件，其配套的高壓進(jìn)線開關(guān)選型直接關(guān)系到設(shè)備和運(yùn)行穩(wěn)定性。不少企業(yè)采購(gòu)或運(yùn)維山東電氣成套設(shè)備時(shí)，都會(huì)困惑：多大容量的變壓器該用負(fù)荷開關(guān)，多大的該用斷路器？負(fù)荷開關(guān)與熔斷器又適配哪些情況？其實(shí)答案很明確，核心就是看變壓器的容量大小。今天就專門圍繞這個(gè)問(wèn)題科普，幫大家理清不同容量變壓器對(duì)應(yīng)的開關(guān)選型邏輯。

　　In the configuration of Shandong Electric's complete set of equipment, transformers are the core components of power conversion, and the selection of their matching high-voltage incoming line switches directly affects the safety and operational stability of the equipment. Many companies are confused when purchasing or operating complete sets of equipment from Shandong Electric: what capacity transformer should use a load switch, and what size should use a circuit breaker? What are the suitable situations for load switches and fuses? The answer is actually very clear, the core is to look at the capacity of the transformer. Today, we will focus on this topic to popularize science and help everyone clarify the switch selection logic corresponding to transformers of different capacities.

　　步，做好日常巡檢，把故障隱患消滅在萌芽狀態(tài)。日常巡檢是運(yùn)維的基礎(chǔ)，要盯緊三個(gè)方面。是外觀檢查，逐一查看山東電氣成套的高低壓開關(guān)柜、變壓器、電纜頭等核心設(shè)備，有沒(méi)有滲油、漏油的情況，運(yùn)行時(shí)有沒(méi)有異常聲響或刺鼻異味，柜體是否存在變形、銹蝕，接地裝置是否牢固可靠，這些直觀的異常往往是故障的前兆。其次是儀表監(jiān)測(cè)，密切觀察電壓表、電流表、功率因數(shù)表的數(shù)值變化，確認(rèn)電壓是否穩(wěn)定、有沒(méi)有過(guò)載運(yùn)行，同時(shí)關(guān)注三相電流是否平衡，避免因三相不平衡導(dǎo)致設(shè)備過(guò)熱。是指示燈狀態(tài)檢查，分合閘指示燈、保護(hù)裝置告警燈等是否正常亮起或熄滅，沒(méi)有異常閃爍、常亮不熄的情況，確保設(shè)備運(yùn)行狀態(tài)清晰可辨。

　　The first step is to conduct daily inspections and eliminate potential faults in their early stages. Daily inspection is the foundation of operation and maintenance, and the focus should be on three aspects. Firstly, the appearance inspection is conducted to examine the core equipment of Shandong Electric's complete set of high and low voltage switchgear, transformers, cable heads, etc., one by one, for any oil leakage or seepage, any abnormal sounds or pungent odors during operation, whether the cabinet is deformed or corroded, and whether the grounding device is firm and reliable. These intuitive abnormalities are often precursors to faults. Next is instrument monitoring, closely observing the numerical changes of the voltmeter, ammeter, and power factor meter to confirm whether the voltage is stable and whether there is overload operation. At the same time, pay attention to whether the three-phase current is balanced to avoid equipment overheating caused by three-phase imbalance. Finally, check the status of the indicator lights, whether the opening and closing indicator lights, protection device alarm lights, etc. are on or off normally, and whether there are any abnormal flashes or constant lights, ensuring that the equipment's operating status is clear and distinguishable.

　　第二步，按周期開展定期維護(hù)，保障設(shè)備長(zhǎng)期穩(wěn)定運(yùn)行。日常巡檢之外，定期維護(hù)必須按既定周期執(zhí)行，不能敷衍。一是清潔除塵，定期清理山東電氣成套設(shè)備表面和柜內(nèi)的灰塵、雜物，尤其是高低壓開關(guān)柜內(nèi)部的元器件和接線端子，灰塵堆積過(guò)多容易導(dǎo)致絕緣性能下降，甚引發(fā)短路故障。二是接線檢查，逐一緊固母排、接線端子的螺栓，防止因長(zhǎng)期運(yùn)行振動(dòng)導(dǎo)致松動(dòng)發(fā)熱，同時(shí)檢查導(dǎo)線的絕緣層是否有老化、開裂、破損的情況，發(fā)現(xiàn)問(wèn)題及時(shí)更換。三是絕緣測(cè)試，用兆歐表定期測(cè)量電纜、開關(guān)設(shè)備的絕緣電阻，確保數(shù)值符合標(biāo)準(zhǔn)，避免因絕緣失效引發(fā)漏電或短路。四是保護(hù)裝置校驗(yàn)，對(duì)微機(jī)保護(hù)裝置、繼電器等核心保護(hù)部件進(jìn)行校驗(yàn)，確保過(guò)流、接地、過(guò)載等保護(hù)功能準(zhǔn)確可靠，關(guān)鍵時(shí)刻能正常動(dòng)作。

　　The second step is to carry out regular maintenance according to the cycle to ensure the long-term stable operation of the equipment. In addition to daily inspections, regular maintenance must be carried out according to established cycles and cannot be perfunctory. One is to clean and remove dust, regularly cleaning the surface and cabinets of Shandong Electric's complete equipment, especially the components and wiring terminals inside the high and low voltage switchgear. Excessive dust accumulation can easily lead to a decrease in insulation performance and even cause short circuit faults. The second is wiring inspection, tightening the bolts of the busbar and wiring terminals one by one to prevent loosening and heating caused by long-term operation vibration. At the same time, check whether the insulation layer of the wire is aging, cracking, or damaged, and replace it in a timely manner if any problems are found. The third is insulation testing, which uses a megohmmeter to regularly measure the insulation resistance of cables and switchgear to ensure that the values meet the standards and avoid leakage or short circuits caused by insulation failure. The fourth is the verification of protection devices, which verifies the core protection components such as microcomputer protection devices and relays to ensure accurate and reliable protection functions such as overcurrent, grounding, and overload, and can operate normally at critical moments.

　　第三步，妥善處理特殊情況，避免故障擴(kuò)大。除了常規(guī)運(yùn)維，遇到特殊情況更要精準(zhǔn)應(yīng)對(duì)。比如雷雨天氣過(guò)后，要檢查山東電氣成套系統(tǒng)中的避雷器、接地系統(tǒng)是否完好，有沒(méi)有雷擊損壞的痕跡，接地電阻是否符合要求，防止雷擊殘留隱患影響系統(tǒng)。在負(fù)荷高峰期，比如夏季高溫或冬季供暖期間，要適當(dāng)加強(qiáng)巡檢頻次，監(jiān)測(cè)變壓器、開關(guān)柜等設(shè)備的溫度，必要時(shí)采取降溫措施，防止設(shè)備因過(guò)載過(guò)熱出現(xiàn)故障。如果出現(xiàn)故障跳閘，千萬(wàn)不能盲目送電，要先查看保護(hù)裝置的故障記錄，根據(jù)記錄精準(zhǔn)排查故障點(diǎn)，徹底排除隱患后，才能重新合閘恢復(fù)供電，避免二次故障造成更大損失。

　　The third step is to handle special situations properly to avoid the expansion of the fault. In addition to regular operations and maintenance, it is even more important to respond accurately in special situations. For example, after a thunderstorm, it is important to focus on checking whether the lightning arrester and grounding system in Shandong Electric's complete system are intact, whether there are any traces of lightning damage, and whether the grounding resistance meets the requirements to prevent residual lightning hazards from affecting system safety. During peak load periods, such as high temperatures in summer or heating periods in winter, it is necessary to increase the frequency of inspections and focus on monitoring the temperature of equipment such as transformers and switchgear. If necessary, cooling measures should be taken to prevent equipment from malfunctioning due to overload and overheating. If there is a fault tripping, do not blindly power on. First, check the fault records of the protective device, accurately identify the fault point based on the records, and thoroughly eliminate the hidden dangers before closing the circuit again to restore power supply and avoid further losses caused by secondary faults.

　　必須強(qiáng)調(diào)核心規(guī)范：不管是日常巡檢還是定期維護(hù)，運(yùn)維人員都要嚴(yán)格遵守電力規(guī)程，做好停電、驗(yàn)電、接地、懸掛警示標(biāo)識(shí)等措施，確保人身和設(shè)備。這是運(yùn)維工作的底線，不能馬虎。另外，對(duì)于復(fù)雜的維護(hù)工作，比如保護(hù)裝置深度校驗(yàn)、大型設(shè)備檢修等，建議由的山東電氣成套技術(shù)團(tuán)隊(duì)操作，避免因個(gè)人技術(shù)不足導(dǎo)致操作失誤。

　　Finally, it is necessary to emphasize the core safety regulations: whether it is daily inspections or regular maintenance, operation and maintenance personnel must strictly abide by the power safety regulations, take safety measures such as power outages, electricity inspections, grounding, hanging warning signs, etc., to ensure personal and equipment safety. This is the bottom line of operation and maintenance work, and we must not be careless. In addition, for complex maintenance work, such as deep verification of protective devices, maintenance of large equipment, etc., it is recommended to have a professional Shandong Electric complete technical team operate to avoid operational errors caused by insufficient personal skills.

　　給山東本地企業(yè)的運(yùn)維管理提個(gè)實(shí)用建議：可以把這套運(yùn)維流程整理成標(biāo)準(zhǔn)化操作手冊(cè)，結(jié)合山東電氣成套設(shè)備的具體型號(hào)和運(yùn)行場(chǎng)景，明確巡檢周期、維護(hù)項(xiàng)目和責(zé)任人，貼在配電房顯眼位置，方便運(yùn)維人員隨時(shí)查看執(zhí)行。同時(shí)，定期組織運(yùn)維人員開展培訓(xùn)演練，熟悉流程和規(guī)范，提升應(yīng)急處置能力。畢竟10kV配電系統(tǒng)是企業(yè)生產(chǎn)的“電力命脈”，規(guī)范的運(yùn)維工作能有效減少故障停機(jī)時(shí)間，降低風(fēng)險(xiǎn)。

　　A practical suggestion for the operation and maintenance management of local enterprises in Shandong: This set of operation and maintenance procedures can be organized into a standardized operation manual, combined with the specific models and operating scenarios of Shandong Electric's complete equipment, to clarify the inspection cycle, maintenance projects, and responsible persons, and posted in a prominent position in the distribution room for easy viewing and execution by operation and maintenance personnel at any time. At the same time, regularly organize training and drills for operation and maintenance personnel to familiarize themselves with processes and safety regulations, and enhance emergency response capabilities. After all, the 10kV distribution system is the "power lifeline" of enterprise production, and standardized operation and maintenance work can effectively reduce downtime and safety risks.

　　總結(jié)下來(lái)，山東電氣成套10kV配電系統(tǒng)的運(yùn)行維護(hù)，核心就是“日常巡檢不松懈、定期維護(hù)按周期、特殊情況精準(zhǔn)處置”，再加上嚴(yán)格遵守規(guī)范。掌握這套實(shí)用流程，能幫助運(yùn)維人員開展工作，保障配電系統(tǒng)穩(wěn)定可靠運(yùn)行。如果大家在山東電氣成套10kV配電系統(tǒng)的運(yùn)維過(guò)程中遇到特殊問(wèn)題，建議及時(shí)咨詢?cè)O(shè)備廠家的技術(shù)人員，獲取精準(zhǔn)的解決方案，避免盲目操作。

　　In summary, the core of the operation and maintenance of Shandong Electric's complete 10kV distribution system is to "not slack off in daily inspections, maintain regularly according to cycles, and handle special situations accurately", coupled with strict adherence to safety regulations. Mastering this practical process can help operation and maintenance personnel efficiently carry out their work and ensure the stable and reliable operation of the distribution system. If you encounter special problems during the operation and maintenance of Shandong Electric's complete 10kV distribution system, it is recommended to consult the professional technical personnel of the equipment manufacturer in a timely manner to obtain accurate solutions and avoid blind operation.
