Low voltage drawer type switchgear is favored by many power engineering customers due to its advantages such as convenient maintenance, multiple group outgoing circuits, and small footprint. Although there are many manufacturers in the field, there are varying levels of technical expertise and production volume. Many small and medium-sized switch factories, due to their weak technical foundation, do not have a grasp of the specifications and standards related to the machinery and equipment in the distribution room. There are risks in the design and installation of drawer cabinets and switch cabinets, coupled with poor customer operation and maintenance management, and the aging of components in the cabinets due to increased operating time, This will lead to a high incidence of high-voltage switchgear accidents and even major accidents such as burning damage

Common fault causes

The temperature inside the cabinet is too high. Long term load operation, long-term current carrying capacity of conductors, and lack of maintenance and upkeep of the cabinet body, resulting in severe ash in the cabinet volume, overall poor heat removal, no dehumidification or air conditioning temperature reduction equipment in the distribution room, and high temperature operation of the power switch itself and transmission lines, resulting in reduced overall characteristics and reduced service life. Aging of machinery, equipment, and routes. Due to the lack of power outage inspection standards in operation and long-term operation, key components have not been immediately maintained, inspected, or replaced, accelerating the aging of machinery, equipment, and routes, and reducing their lifespan.

Response measures

The incoming and outgoing conductors in the drawer cabinet should use reliable cable cables or grounding copper bars containing insulation layer heat shrink sleeves, and be installed in accordance with relevant national industry standards; The power distribution room should enable the opening of equipment monitoring system software for easy reading and viewing of machine equipment operation. Perform data analysis on historical records and compare specific operational data information to immediately detect anomalies and prevent them from occurring. At the same time, the distribution room should enhance the management methods of the ventilation system, and the output power and efficiency of the ventilation system should meet the requirements of normal operation; The operating bottom pressure cabinet in the distribution room should undergo quality inspection on time, mainly for key components such as internal power switches, copper transmission lines, connectors, etc., which need to be disassembled and replaced when necessary.

The required loads in the distribution room should be managed in a standardized manner and labeled one by one. For very critical and critical loads, protective equipment should be enhanced, and targeted inspection plans should be formulated and executed in a floor mounted manner; Timely conduct reasonable technical training for institutional operation and maintenance management staff and distribution room managers, such as research and training on knowledge of distribution room operation and maintenance management, emergency response to sudden abnormalities, prevention, and other topics. Conduct emergency plan drills and practical operation evaluations on time, and enhance the skill level of staff and communication ability to solve emergency problems in multiple aspects.

summary

Low voltage drawer cabinets are key distribution equipment for the bottom pressure system software in the distribution room. According to accident expectations, high-voltage switchgear manufacturers attach great importance to them and should strictly follow national industry standards for design, production, and installation. As power engineering customers, they should also carry out regular maintenance, upkeep, and upkeep of the machinery and equipment to ensure their normal operation together.
