虽然行业内生产MNS低压抽屉柜的厂家众多，但技术和产能参差不齐，抽屉式开关柜的设计和组装存在隐患。下面简单说一下MNS低压抽屉柜的其他故障原因分析。

Although there are many manufacturers producing MNS low-voltage drawer cabinets in the industry, the technology and production capacity are uneven, and there are potential safety hazards in the design and assembly of drawer type switchgear. The following is a brief introduction to the cause analysis of other faults of MNS low-voltage drawer cabinet.

MNS低压抽屉柜其他故障原因

Other fault causes of MNS low voltage drawer cabinet

机柜内温度过高。高负荷运行，导体长期流动，柜体缺乏维护，导致柜体积灰严重，整体散热差，无，配电室无空调制冷设施，高温运行开关本体和线材，整体性能下降，寿命缩短。

The temperature in the cabinet is too high. High load operation, long-term conductor flow and lack of maintenance of the cabinet lead to serious ash in the cabinet volume, poor overall heat dissipation, no dehumidification, no air conditioning and refrigeration facilities in the distribution room, and high-temperature operation of the switch body and wire, resulting in reduced overall performance and shortened service life.

设备和线路老化。配电室于正式投入运行今已连续运行十几年。由于运行条件不符合停电检查条件，长期连续运行。核心部件未及时维护、测试和更换。并且线路老化，使用寿命降低。

Aging of equipment and lines. The power distribution room has been in continuous operation for more than ten years since it was officially put into operation. Because the operation conditions do not meet the power failure inspection conditions, it operates continuously for a long time. Core components are not maintained, tested and replaced in time. Moreover, the circuit is aging and the service life is reduced.

抽屉柜内进出线的导体应采用普通低压电缆或包覆绝缘热缩管的铜排，并按有关标准安装；配电室应确保设备监控系统处于开启状态，以便于访问和检查设备运行状态。对历史数据进行统计分析，对标实际运行数据，及时发现异常，隐患。

The conductors of incoming and outgoing lines in the drawer cabinet shall be ordinary low-voltage cables or copper bars coated with insulated heat shrinkable tubes, and shall be installed according to relevant national standards; The power distribution room shall ensure that the equipment monitoring system is turned on for easy access and inspection of equipment operation status. Carry out statistical analysis on historical data, benchmark actual operation data, timely find abnormalities and eliminate hidden dangers.

同时，配电室要加强对送风和排风系统的管理，送风和排风的功率和效率要满足正常运行要求；配电室运行的低压柜应定期检查质量，特别是内部开关、铜线、连接器等，必要时更换核心部件。

At the same time, the power distribution room shall strengthen the management of air supply and exhaust system, and the power and efficiency of air supply and exhaust shall meet the requirements of normal operation; The quality of low-voltage cabinets operating in the distribution room shall be regularly checked, especially the internal switches, copper wires, connectors, etc., and the core components shall be replaced if necessary.

配电室所承载的负荷应一一分类标记。对非常重要和重要的负荷应增加必要的保护装置，并制定和实施有针对性的运行和检查计划。定期组织运维人员和配电室管理人员进行检查。有效的技能培训，如配电室运维知识、突发事件应急处理、防护等专题，并定期开展应急演练和实战考核，提升人员应对突发事件的技能和能力。

The load carried by the distribution room shall be marked one by one. Necessary protective devices shall be added for very important and important loads, and targeted operation and inspection plans shall be formulated and implemented. Regularly organize the operation and maintenance personnel and the management personnel of the power distribution room for inspection. Effective skills training, such as distribution room operation and maintenance knowledge, emergency handling, safety protection and other topics, and regular emergency drills and practical assessments are carried out to comprehensively improve personnel's skills and abilities to deal with emergencies.
