　　5、 Selection and maintenance selection skills: When selecting high and low voltage complete sets of equipment, factors such as technical parameters, actual usage requirements, selection of electrical components, and total investment control need to be considered. At the same time, it is necessary to ensure that all factory products comply with 3C certification requirements to ensure consistency in product quality. Operation and maintenance: During the operation and maintenance of high and low voltage complete sets of equipment, attention should be paid to observing the status of each component, checking for overheating, discoloration, abnormal noise, poor contact, and other phenomena. At the same time, the distribution room should be moisture-proof, dust-proof, and prevent small animals from entering. For equipment that has not been put into operation for a long time, heating and dehumidification should be carried out before operation to prevent condensation from affecting the external insulation of the equipment. In addition, all metal parts should be rust resistant (coated with clear varnish or colored paint), moving parts should be lubricated carefully, screws should be checked for looseness, and dust should be removed in a timely manner.

　　六、性能特点高低压成套设备具有出色的性能、高度的可靠性和稳定性以及灵活的扩展性和可定制性。它们采用的电气保护装置和多重措施，能够及时检测和隔离电力故障，有效避免因电气问题引发的火灾等事故。同时，这些设备还具备过载、短路、漏电等多种保护功能，能够确保设备在各种异常情况下正常运行并保护设备和人员的。此外，高低压成套设备采用模块化设计，可以根据不同的需求和应用场景进行灵活组合和扩展以满足不同设备的控制要求。

　　6、 The high and low voltage complete equipment has excellent safety performance, high reliability and stability, as well as flexible scalability and customizability.
