山東電氣成套設備里，高低壓柜門(mén)指示燈有啥講究？

　　What are the requirements for the high and low voltage cabinet door indicator lights in Shandong Electric's complete set of equipment?

　　在山東的工廠(chǎng)車(chē)間、配電房里，山東電氣成套設備中的高低壓柜隨處可見(jiàn)。細心的人會(huì )發(fā)現，高低壓柜的門(mén)上都裝著(zhù)不同顏色的指示燈，常見(jiàn)的就是紅色和綠色，偶爾還能看到黃色的。不少從事電力運維的朋友或采購山東電氣成套設備的企業(yè)負責人，都會(huì )疑惑：這些指示燈到底有啥講究？為啥合閘要用紅色燈，分閘卻用綠色燈？今天就專(zhuān)門(mén)圍繞山東電氣成套設備中的高低壓柜門(mén)指示燈，給大家把這些疑問(wèn)講明白。

　　High and low voltage cabinets can be seen everywhere in the factory workshops and distribution rooms of Shandong Electric's complete equipment. Observant people will notice that the doors of high and low voltage cabinets are equipped with indicator lights of different colors, with the most common being red and green, and occasionally yellow. Many friends engaged in power operation and maintenance, or business leaders who purchase complete sets of equipment from Shandong Electric, may wonder: What are the requirements for these indicator lights? Why is a red light used for closing the switch, but a green light is used for opening the switch? Today, we will specifically focus on the high and low voltage cabinet door indicator lights in Shandong Electric's complete set of equipment, and explain these questions to everyone.

　　要明確，高低壓柜門(mén)的指示燈可不是隨便裝的，顏色選擇更不是廠(chǎng)家說(shuō)了算，而是有明確的行業(yè)標準規定。這背后的核心邏輯，是利用大家對顏色的普遍認知來(lái)傳遞信號，畢竟電力操作容不得半點(diǎn)馬虎，清晰的信號提示能直接降低操作風(fēng)險。就像我們過(guò)馬路時(shí)看紅綠燈一樣，紅色和綠色的含義早已形成共識，這種共識也被沿用在了山東電氣成套設備的高低壓柜上。

　　First of all, it should be clear that the indicator lights on the high and low voltage cabinet doors are not installed casually, and the color selection is not the the final say of the manufacturer, but there are clear industry standards. The core logic behind this is to use everyone's general understanding of colors to convey safety signals, after all, power operation cannot tolerate any carelessness, and clear signal prompts can directly reduce operational risks. Just like when we look at traffic lights when crossing the street, the meanings of red and green have already formed a consensus, which has been used in the high and low voltage cabinets of Shandong Electric's complete equipment.

　　先說(shuō)說(shuō)紅色燈，它的核心含義是“危險、禁止”。這和紅綠燈里紅燈表示禁止通行的邏輯完全一致，在高低壓柜上，紅燈亮就代表設備處于合閘狀態(tài)。合閘意味著(zhù)電路接通，設備正在帶電工作，這時(shí)候不能隨意打開(kāi)柜門(mén)進(jìn)行檢修或觸碰內部部件，否則很容易引發(fā)觸電、電弧灼傷等事故。對山東工業(yè)場(chǎng)景中的運維人員來(lái)說(shuō)，看到紅燈亮就會(huì )立刻繃緊弦，明確當前設備處于危險工作狀態(tài)，避免誤操作。

　　Let's talk about the red light first, its core meaning is "danger, prohibition". This is completely consistent with the logic of red lights indicating prohibition of passage in traffic lights. On high and low voltage cabinets, a red light indicates that the equipment is in a closed state. Closing means that the circuit is connected and the equipment is working with electricity. At this time, it is absolutely not allowed to open the cabinet door for maintenance or touch internal components at will, otherwise it is easy to cause safety accidents such as electric shock and arc burns. For operation and maintenance personnel in Shandong's industrial scene, when the red light is on, they will immediately tighten the safety string, clarify that the current equipment is in a dangerous working state, and avoid misoperation.

　　再看綠色燈，它對應的含義是“、允許”，和紅綠燈里綠燈表示可以通行的意思相呼應。在高低壓柜上，綠燈亮說(shuō)明設備處于分閘狀態(tài)，此時(shí)電路已經(jīng)斷開(kāi)，設備不帶電。對山東的電力運維人員而言，這就是明確的“信號”——只有看到綠燈亮，確認設備分閘斷電后，才能按照規范流程打開(kāi)柜門(mén)，進(jìn)行內部檢修、維護或更換部件。這種顏色提示簡(jiǎn)單直接，哪怕是新手運維人員，也能快速判斷設備狀態(tài)，降低操作失誤的概率。

　　Looking at the green light again, its corresponding meaning is "safe, allowed", which corresponds to the green light in traffic lights indicating that traffic is allowed. On the high and low voltage cabinets, a green light indicates that the equipment is in the open state, and the circuit has been disconnected, rendering the equipment non energized. For the power operation and maintenance personnel in Shandong, this is a clear "safety signal" - only when they see the green light on and confirm that the equipment is disconnected and powered off, can they open the cabinet door according to the standard process for internal inspection, maintenance, or component replacement. This color prompt is simple and direct, even novice operation and maintenance personnel can quickly determine the equipment status, reducing the probability of operational errors.

　　除了常見(jiàn)的紅、綠兩色，有些山東電氣成套的高低壓柜上還會(huì )有黃色指示燈，它的含義是“警告、注意”。這種黃色燈一般不會(huì )單獨用來(lái)表示分合閘狀態(tài)，更多是用于提示設備的異常情況，比如電路出現過(guò)載、故障預警等。當黃色燈亮起時(shí)，就提醒運維人員需要及時(shí)檢查設備，排查潛在問(wèn)題，避免小故障發(fā)展成大事故。不過(guò)要注意，黃色燈的具體提示含義會(huì )因設備型號不同略有差異，操作前查看設備說(shuō)明書(shū)。

　　In addition to the most common red and green colors, some high and low voltage cabinets of Shandong Electric also have yellow indicator lights, which mean "warning, attention". This yellow light is generally not used alone to indicate the opening and closing status, but is more used to indicate abnormal situations of the equipment, such as circuit overload, fault warning, etc. When the yellow light is on, it reminds the operation and maintenance personnel to check the equipment in a timely manner, identify potential problems, and avoid small faults from developing into major accidents. However, it should be noted that the specific meaning of the yellow light may vary slightly depending on the device model. It is best to check the device manual before operation.

　　可能有人會(huì )問(wèn)，為啥非要遵循這樣的顏色標準？對山東電氣成套設備來(lái)說(shuō)，標準化的顏色指示燈是保障電力的重要細節。山東作為工業(yè)大省，不管是重型工業(yè)、制造業(yè)還是新能源產(chǎn)業(yè)，都離不開(kāi)穩定可靠的電氣成套設備，而高低壓柜作為電力分配的核心部件，其操作直接關(guān)系到生產(chǎn)。如果指示燈顏色不統一，不同廠(chǎng)家用不同顏色表示相同狀態(tài)，運維人員在操作不同設備時(shí)很容易混淆，進(jìn)而引發(fā)事故。所以山東本地的電氣成套設備廠(chǎng)家，在生產(chǎn)高低壓柜時(shí)，都會(huì )嚴格遵循和行業(yè)標準，確保指示燈顏色和含義統一規范。

　　Some people may ask, why do we have to follow such color standards? For Shandong Electric's complete equipment, standardized color indicator lights are important details to ensure power safety. As a major industrial province, Shandong cannot do without stable and reliable electrical equipment for heavy industry, manufacturing, and new energy industries. As the core component of power distribution, the operation safety of high and low voltage cabinets is directly related to production safety. If the color of the indicator lights is not uniform and different manufacturers use different colors to represent the same status, it is easy for operation and maintenance personnel to confuse different brands of equipment, which can lead to safety accidents. So local electrical equipment manufacturers in Shandong strictly follow national and industry standards when producing high and low voltage cabinets, ensuring that the colors and meanings of indicator lights are standardized and consistent.

　　給山東本地的企業(yè)和運維人員提個(gè)實(shí)用建議：在選用和操作山東電氣成套的高低壓柜時(shí)，要確認設備指示燈符合相關(guān)標準，避免選用非標產(chǎn)品；其次，操作前一定要先觀(guān)察指示燈顏色，牢記“紅燈合閘危險、綠燈分閘”的核心原則，不能在紅燈亮時(shí)強行打開(kāi)柜門(mén)；另外，日常維護中也要注意檢查指示燈是否正常工作，比如有沒(méi)有不亮、閃爍異常等情況，發(fā)現問(wèn)題及時(shí)處理，確保指示燈能準確傳遞信號。

　　Finally, a practical suggestion for local enterprises and operation and maintenance personnel in Shandong: when selecting and operating the high and low voltage cabinets of Shandong Electric, the first step is to confirm that the equipment indicator lights comply with relevant standards and avoid using non-standard products; Secondly, before operation, it is necessary to observe the color of the indicator light and remember the core principle of "dangerous closing of the red light and safe opening of the green light". It is absolutely not allowed to forcefully open the cabinet door when the red light is on; In addition, during daily maintenance, attention should also be paid to checking whether the indicator lights are working properly, such as whether they are not on or flashing abnormally. If any problems are found, they should be dealt with in a timely manner to ensure that the indicator lights can accurately transmit safety signals.
