當前，在發(fā)電廠(chǎng)、住宅樓的低壓配電工作環(huán)境下，普遍使用抽屜式低壓開(kāi)關(guān)柜，特別是MNS抽屜式低壓開(kāi)關(guān)柜得到了廣泛應用。雖然業(yè)內生產(chǎn)MNS低壓抽屜柜的廠(chǎng)家很多，但技術(shù)和質(zhì)量參差不齊，抽屜式開(kāi)關(guān)柜的設計和組裝存在隱患，下面簡(jiǎn)單說(shuō)一下MNS低壓抽屜柜的其他故障原因分析。

Currently, in the low-voltage distribution working environment of power plants and residential buildings, drawer type low-voltage switchgear is widely used, especially MNS drawer type low-voltage switchgear has been widely used. Although there are many manufacturers producing MNS low-voltage drawer cabinets in the industry, their technology and quality are uneven, and there are safety hazards in the design and assembly of drawer type switchgear. Below is a brief analysis of other fault causes of MNS low-voltage drawer cabinets.

在使用中，機柜內的溫度太高，高負荷運行，導體長(cháng)時(shí)間流動(dòng)，機柜缺乏維護，導致積灰嚴重，整體散熱差，無(wú)，配電室無(wú)空調制冷設施，開(kāi)關(guān)本體和導線(xiàn)高溫運行，導致整體性能下降，使用壽命縮短，以及設備和線(xiàn)路的老化等都會(huì )使低壓柜產(chǎn)生故障。如配電室從正式投入運行今，已經(jīng)連續運行了十幾年，因運行條件不符合停電檢查條件而長(cháng)期連續運行，核心部件沒(méi)有及時(shí)維護、測試更換、線(xiàn)路老化、使用壽命降低， 抽屜柜內進(jìn)出線(xiàn)的導線(xiàn)應為普通低壓電纜或包絕緣熱縮管的銅排，并按相關(guān)標準安裝，配電室應確保設備監控系統開(kāi)啟，以便訪(fǎng)問(wèn)和檢查設備的運行狀態(tài)。

During use, the temperature inside the cabinet is too high, the load is high, the conductors flow for a long time, the cabinet lacks maintenance, resulting in severe ash accumulation, poor overall heat dissipation, no dehumidification, no air conditioning and refrigeration facilities in the distribution room, high temperature operation of the switch body and wires, resulting in a decrease in overall performance, shortened service life, and aging of equipment and circuits, all of which can cause faults in the low-voltage cabinet. If the power distribution room has been in continuous operation for more than ten years since it was officially put into operation, and the operating conditions do not meet the power outage inspection conditions, the core components have not been maintained, tested and replaced in a timely manner, the circuit has aged, and the service life has decreased. The wires for the incoming and outgoing lines in the drawer cabinet should be ordinary low-voltage cables or copper bars wrapped in insulated heat shrink tubes, and installed according to relevant national standards. The power distribution room should ensure that the equipment monitoring system is turned on, To access and check the operational status of the device.

統計分析歷史數據，對標實(shí)際運行數據，及時(shí)發(fā)現異常，隱患，同時(shí)，配電室應加強送排風(fēng)系統的管理，送排風(fēng)的功率和效率應滿(mǎn)足正常運行的要求，應定期檢查配電室運行的低壓柜的質(zhì)量，尤其是內部開(kāi)關(guān)、銅線(xiàn)、接插件，必要時(shí)更換核心部件。配電室承載的負荷應分類(lèi)并逐一標記，對非常重要和重要的負荷應增加必要的保護裝置，并制定和實(shí)施有針對性的運行和檢查計劃，組織運行維護人員和配電室管理人員定期檢查。有效的技能培訓，如配電室運維知識、應急處理、防護等，并定期進(jìn)行應急演練和實(shí)戰考核，提高人員處置突發(fā)事件的技能和能力。

Statistical analysis of historical data, benchmarking of actual operating data, timely detection of anomalies, elimination of hidden dangers, and strengthening of the management of the supply and exhaust system in the distribution room. The power and efficiency of the supply and exhaust air should meet the requirements of normal operation. The quality of the low-voltage cabinets in the distribution room should be regularly checked, especially the internal switches, copper wires, and connectors. If necessary, core components should be replaced. The loads carried by the distribution room should be classified and marked one by one. Necessary protective devices should be added for very important and important loads, and targeted operation and inspection plans should be developed and implemented. Regular inspections should be organized by operation and maintenance personnel and distribution room management personnel. Effective skill training, such as knowledge of power distribution room operation and maintenance, emergency response, safety protection, etc., and regular emergency drills and practical assessments, to comprehensively improve personnel's skills and abilities in handling emergencies.
