MNS低壓抽屜柜高負荷運行，導(dǎo)體長時通流，而且柜體缺乏維護，導(dǎo)致柜體積灰嚴重，整體散熱不良，配電室無、無空調(diào)降溫設(shè)施，開關(guān)本體及導(dǎo)線高溫運行，整體性能下降，壽命降低。設(shè)備及線路老化。連續(xù)長時間運行，核心部件未得到及時的保養(yǎng)、檢測、更換，加速設(shè)備及線路老化，使用壽命降低。

The MNS low-voltage drawer cabinet operates under high load, with its conductors passing through for a long time, and the cabinet body lacks maintenance, resulting in severe ash in the cabinet volume, poor overall heat dissipation, lack of dehumidification and air-conditioning cooling facilities in the distribution room, and high temperature operation of the switch body and conductors, resulting in reduced overall performance and reduced service life. Aging of equipment and lines. During continuous long time operation, core components are not maintained, tested, and replaced in a timely manner, accelerating the aging of equipment and circuits, and reducing their service life.

應(yīng)對措施

Countermeasures

抽屜柜中進出線導(dǎo)體應(yīng)選用正規(guī)低壓電纜或者帶有絕緣熱縮管包覆的銅排，并按照相關(guān)標準進行安裝；配電室應(yīng)確保開啟設(shè)備監(jiān)控系統(tǒng)，以便于調(diào)取、查閱設(shè)備運行狀態(tài)。針對歷史數(shù)據(jù)做好統(tǒng)計分析，并對標實際運行數(shù)據(jù)，及時發(fā)現(xiàn)異常并隱患。

The incoming and outgoing conductors in the drawer cabinet should be regular low-voltage cables or copper bars covered with insulated heat shrinkable tubes, and installed in accordance with relevant national standards; The power distribution room should ensure that the equipment monitoring system is turned on to facilitate access and review of equipment operation status. Conduct statistical analysis on historical data, benchmark actual operation data, timely detect anomalies and eliminate hidden dangers.

同時配電室應(yīng)加強送排風(fēng)系統(tǒng)的管理，送排風(fēng)功率及效能應(yīng)滿足正常運行需求；配電室內(nèi)的運行低壓柜應(yīng)定期進行質(zhì)量排查，尤其針對內(nèi)部開關(guān)、銅導(dǎo)線、插接件等核心部件，必要時進行更換。

At the same time, the power distribution room should strengthen the management of the air supply and exhaust system, and the power and efficiency of the air supply and exhaust should meet the requirements of normal operation; The operating low-voltage cabinet in the power distribution room should undergo regular quality inspections, especially for core components such as internal switches, copper conductors, connectors, and the like, and should be replaced if necessary.

配電室所帶負載應(yīng)進行分級分類并逐一進行標識，對非常重要及重要負荷應(yīng)增加必要的保護裝置，制定針對性運檢計劃并落地實施；定期組織運維人員及配電室管理人員進行有效的技能培訓(xùn)，比如配電室運維知識、突發(fā)異常緊急處理、防護等課題培訓(xùn)，并定期開展應(yīng)急演練及實操考核，提升人員技能水平和應(yīng)對突發(fā)事件的應(yīng)變能力。

The loads carried in the distribution room should be classified and identified one by one. Necessary protective devices should be added for very important and important loads, and targeted operational inspection plans should be developed and implemented; Regularly organize effective skill training for operation and maintenance personnel and power distribution room management personnel, such as training on topics such as power distribution room operation and maintenance knowledge, emergency handling of sudden abnormalities, safety protection, etc., and regularly carry out emergency drills and practical assessment to comprehensively improve personnel's skill level and response ability to sudden events.

MNS低壓抽屜柜是配電室低壓系統(tǒng)的重要配電裝置，通過此次事故希望能引起開關(guān)柜生產(chǎn)廠家的重視，應(yīng)嚴格按照標準進行設(shè)計、生產(chǎn)和安裝，作為電力用戶也應(yīng)該對設(shè)備進行定期檢查、維護和保養(yǎng)，才能共同保證設(shè)備正常運行。更多相關(guān)產(chǎn)品事項就來我們網(wǎng)站http://766722.cn咨詢吧！

MNS low-voltage drawer cabinet is an important power distribution device in the low-voltage system of the power distribution room. Through this accident, we hope to attract the attention of the switch cabinet manufacturer. It should be designed, produced, and installed in strict accordance with national standards. As a power user, we should also regularly inspect, maintain, and maintain the equipment in order to jointly ensure the normal and safe operation of the equipment.
