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.
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.
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.
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 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.
