濟(jì)南機(jī)箱機(jī)柜里的高壓柜，電氣距離該留多少？

　　How much electrical distance should be left for the high-voltage cabinet in the Jinan chassis cabinet?

　　在濟(jì)南的工廠、配電房等場(chǎng)景中，濟(jì)南機(jī)箱機(jī)柜生產(chǎn)的高壓柜是電力系統(tǒng)的核心設(shè)備。不少采購高壓柜的企業(yè)負(fù)責(zé)人或電力運(yùn)維人員，都會(huì)關(guān)注一個(gè)關(guān)鍵問題：高壓柜里的電氣距離到底該留多少？其實(shí)電氣距離是高壓柜安全運(yùn)行的“生命線”，直接關(guān)系到設(shè)備是否會(huì)出現(xiàn)短路、放電等故障。今天就專門圍繞濟(jì)南機(jī)箱機(jī)柜中的高壓柜，給大家科普不同電壓等級(jí)對(duì)應(yīng)的電氣距離標(biāo)準(zhǔn)，把這些關(guān)鍵數(shù)據(jù)和注意事項(xiàng)講明白。

　　In factories, distribution rooms, and other scenarios in Jinan, the high-voltage cabinets produced by Jinan chassis cabinets are the core equipment of the power system. Many business leaders or power operation and maintenance personnel who purchase high-voltage cabinets will pay attention to a key question: how much electrical distance should be left inside the high-voltage cabinet? In fact, electrical distance is the "lifeline" for the safe operation of high-voltage cabinets, directly related to whether equipment will experience faults such as short circuits and discharges. Today, we will specifically focus on the high-voltage cabinet in the Jinan chassis cabinet, to popularize the electrical distance standards corresponding to different voltage levels, and explain these key data and precautions clearly.

　　先給大家解釋下，啥是高壓柜的電氣距離？簡(jiǎn)單說，就是高壓柜內(nèi)部不同帶電部件之間，或者帶電部件與接地部件之間的非常小安全距離。因?yàn)楦邏弘娫谝欢l件下會(huì)發(fā)生空氣擊穿，產(chǎn)生電弧放電，要是電氣距離不夠，就容易引發(fā)短路事故，燒毀設(shè)備甚至引發(fā)火災(zāi)。所以濟(jì)南機(jī)箱機(jī)柜廠家在生產(chǎn)高壓柜時(shí)，都會(huì)嚴(yán)格按照國(guó)家相關(guān)標(biāo)準(zhǔn)預(yù)留電氣距離，而不同電壓等級(jí)的高壓柜，對(duì)應(yīng)的電氣距離要求也不一樣，核心就是電壓越高，需要預(yù)留的安全距離就越大。

　　Let me explain to you first, what is the electrical distance of a high-voltage cabinet? Simply put, it refers to the minimum safe distance between different live parts inside the high-voltage cabinet, or between live parts and grounding parts. Because high voltage electricity can cause air breakdown and arc discharge under certain conditions, if the electrical distance is not sufficient, it is easy to cause short circuit accidents, burn equipment, and even cause fires. So when Jinan chassis and cabinet manufacturers produce high-voltage cabinets, they strictly reserve electrical distance according to relevant national standards. Different voltage levels of high-voltage cabinets have different electrical distance requirements, and the core is that the higher the voltage, the greater the safety distance that needs to be reserved.

　　非常常見的是相與相之間的電氣距離，這是高壓柜設(shè)計(jì)中非常核心的距離要求之一。不同電壓等級(jí)對(duì)應(yīng)的標(biāo)準(zhǔn)很明確，大家可以直接參考：3000V電壓等級(jí)的高壓柜，相與相之間的距離要留夠70毫米；5600V的則需要100毫米；咱們濟(jì)南工業(yè)場(chǎng)景中非常常用的10kV高壓柜，相間距離標(biāo)準(zhǔn)是125毫米，這個(gè)數(shù)據(jù)也是濟(jì)南機(jī)箱機(jī)柜廠家生產(chǎn)10kV高壓柜時(shí)非常常遵循的；20kV電壓等級(jí)的需要180毫米；35kV的則要留足300毫米。這些數(shù)據(jù)都是經(jīng)過大量實(shí)驗(yàn)驗(yàn)證的安全閾值，一點(diǎn)都不能含糊。

　　The most common is the electrical distance between phases, which is one of the core distance requirements in high-voltage cabinet design. The standards corresponding to different voltage levels are very clear, and you can directly refer to them: for a high-voltage cabinet with a voltage level of 3000V, the distance between phases should be sufficient to be 70 millimeters; 5600V requires 100mm; The most commonly used 10kV high-voltage cabinet in our Jinan industrial scene has a phase to phase distance standard of 125 millimeters, which is also the most commonly followed by Jinan chassis cabinet manufacturers when producing 10kV high-voltage cabinets; 180mm is required for a voltage level of 20kV; For 35kV, a sufficient 300mm should be left. These data are security thresholds that have been extensively validated through experiments and cannot be ambiguous at all.

　　不過在實(shí)際生產(chǎn)和安裝中，有時(shí)候會(huì)遇到柜體空間有限，沒辦法預(yù)留足夠相間距離的情況。這時(shí)候也有解決方案——在相間加裝絕緣板。但加裝絕緣板后，也有明確的距離要求，不能隨便裝。具體來說，12kV及以下電壓等級(jí)的高壓柜，加裝絕緣板后，對(duì)應(yīng)的安全距離留夠30毫米就可以；24kV的則需要40.5毫米；35kV的高壓柜加裝絕緣板后，距離要求是60毫米。這種方式既解決了柜體空間不足的問題，又能保證高壓柜的安全運(yùn)行，在濟(jì)南不少小型工廠的高壓柜配置中很常用。

　　However, in actual production and installation, sometimes there may be situations where the cabinet space is limited and it is not possible to reserve enough space between phases. At this point, there is also a solution - installing insulation boards between phases. But after installing the insulation board, there are also clear distance requirements and it cannot be installed casually. Specifically, for high-voltage cabinets with voltage levels of 12kV and below, after installing insulation boards, the corresponding safety distance should be kept at 30mm; For 24kV, 40.5mm is required; After installing insulation boards on the 35kV high-voltage cabinet, the distance requirement is 60mm. This method not only solves the problem of insufficient cabinet space, but also ensures the safe operation of high-voltage cabinets, which is commonly used in the configuration of high-voltage cabinets in many small factories in Jinan.

　　可能有人會(huì)問，為啥濟(jì)南機(jī)箱機(jī)柜廠家都要嚴(yán)格遵守這些電氣距離標(biāo)準(zhǔn)？核心還是為了安全和穩(wěn)定。濟(jì)南作為工業(yè)重鎮(zhèn)，高壓柜廣泛應(yīng)用于各類生產(chǎn)場(chǎng)景，一旦因?yàn)殡姎饩嚯x不達(dá)標(biāo)出現(xiàn)故障，不僅會(huì)導(dǎo)致工廠停產(chǎn)，造成經(jīng)濟(jì)損失，還可能引發(fā)安全事故。而且符合標(biāo)準(zhǔn)的高壓柜，才能通過相關(guān)部門的驗(yàn)收，正常投入使用。所以濟(jì)南本地正規(guī)的機(jī)箱機(jī)柜廠家，在設(shè)計(jì)和生產(chǎn)高壓柜時(shí)，都會(huì)把電氣距離作為核心質(zhì)控點(diǎn)，從圖紙?jiān)O(shè)計(jì)到生產(chǎn)組裝，全程嚴(yán)格把控，確保每一臺(tái)出廠的高壓柜都符合標(biāo)準(zhǔn)要求。

　　Some people may ask, why do Jinan chassis and cabinet manufacturers strictly adhere to these electrical distance standards? The core is still for safety and stability. As an industrial hub, high-voltage cabinets are widely used in various production scenarios in Jinan. Once a fault occurs due to inadequate electrical distance, it not only leads to factory shutdown and economic losses, but also may cause safety accidents. And only high-voltage cabinets that meet the standards can pass the acceptance of relevant departments and be put into normal use. So local legitimate chassis and cabinet manufacturers in Jinan will take electrical distance as the core quality control point when designing and producing high-voltage cabinets. From drawing design to production assembly, they strictly control the entire process to ensure that every high-voltage cabinet leaving the factory meets the standard requirements.

　　給濟(jì)南本地的企業(yè)提個(gè)實(shí)用建議：在采購高壓柜時(shí)，一定要明確自己的電壓等級(jí)需求，然后要求廠家提供符合對(duì)應(yīng)電氣距離標(biāo)準(zhǔn)的產(chǎn)品，非常好讓廠家出具相關(guān)的檢測(cè)報(bào)告，避免買到非標(biāo)產(chǎn)品。另外，在高壓柜的安裝和后期維護(hù)中，也不要隨意改動(dòng)內(nèi)部結(jié)構(gòu)，更不能因?yàn)榭臻g緊張就擅自縮小電氣距離；如果需要對(duì)高壓柜進(jìn)行改造，一定要找專業(yè)的技術(shù)人員，確保改造后仍然符合對(duì)應(yīng)的電氣距離標(biāo)準(zhǔn)。還有就是日常維護(hù)時(shí)，可以留意下內(nèi)部部件是否有移位、變形等情況，一旦發(fā)現(xiàn)可能影響電氣距離的問題，要及時(shí)處理。

　　A practical suggestion for local enterprises in Jinan: When purchasing high-voltage cabinets, it is important to clarify your voltage level requirements and request that the manufacturer provide products that meet the corresponding electrical distance standards. It is best to have the manufacturer provide relevant testing reports to avoid purchasing non-standard products. In addition, during the installation and later maintenance of the high-voltage cabinet, do not arbitrarily modify the internal structure, and do not arbitrarily reduce the electrical distance due to space constraints; If it is necessary to renovate the high-voltage cabinet, it is necessary to find professional technicians to ensure that it still meets the corresponding electrical distance standards after the renovation. Also, during daily maintenance, you can pay attention to whether there is any displacement or deformation of internal components. Once any problems that may affect electrical distance are discovered, they should be dealt with in a timely manner.

　　總結(jié)下來，濟(jì)南機(jī)箱機(jī)柜中高壓柜的電氣距離有明確的標(biāo)準(zhǔn)，核心是電壓越高，相間距離要求越大，空間不足時(shí)可加裝絕緣板并遵循對(duì)應(yīng)距離要求。電氣距離是高壓柜安全運(yùn)行的關(guān)鍵，不管是廠家生產(chǎn)還是企業(yè)使用，都建議嚴(yán)格遵守。了解這些標(biāo)準(zhǔn)，能幫助企業(yè)更好地選用和維護(hù)高壓柜，避免因電氣距離問題引發(fā)故障。如果大家在濟(jì)南高壓柜的采購或電氣距離相關(guān)問題上還有疑問，不妨咨詢專業(yè)的機(jī)箱機(jī)柜廠家，獲取更合理的技術(shù)建議。

　　In summary, there are clear standards for the electrical distance of high-voltage cabinets in Jinan chassis cabinets. The core is that the higher the voltage, the greater the requirement for phase to phase distance. When space is insufficient, insulation boards can be installed and corresponding distance requirements should be followed. Electrical distance is the key to the safe operation of high-voltage cabinets, and must be strictly observed by both manufacturers and enterprises. Understanding these standards can help companies better select and maintain high-voltage cabinets, avoiding faults caused by electrical distance issues. If you have any questions about the procurement of high-voltage cabinets or electrical distance related issues in Jinan, you may consult professional chassis and cabinet manufacturers for more accurate technical advice.
