母线槽作为电力传输的关键设备，在运行过程中可能会出现多种问题，影响电力系统的稳定运行。对于常见问题及时采取应对措施、保障电力供应至关重要。
busway, as a key device for power transmission, may encounter various problems during operation, which affect the stable operation of the power system. It is crucial to take timely countermeasures for common problems to ensure power supply.
母线槽导体多为铜或铝，易受环境侵蚀。如在潮湿、有腐蚀性气体环境中，金属与空气中水分、化学物质反应，产生锈蚀。这会使导体电阻增大，导致电能传输时发热，降低传输效率，长期还可能引发短路。
The conductors ofbusway are mostly made of copper or aluminum, which are susceptible to environmental erosion. For example, in humid environments with corrosive gases, metals react with moisture and chemical substances in the air, causing rust. This increases the resistance of the conductor, leading to heat generation during power transmission, reducing transmission efficiency, and may even cause short circuits in the long term.
母线槽运行中的振动、热胀冷缩等，会使导体接头处螺丝松动，造成接触不良。接触电阻增大，产生局部高温，甚至出现火花，严重时影响供电稳定性。
Vibrations, thermal expansion and contraction, etc., during the operation ofbusway will loosen the screws at the conductor joints, resulting in poor contact. The increased contact resistance generates local high temperatures or even sparks, seriously affecting the stability of power supply.
母线槽长时间运行、温度变化、电气应力等，会使绝缘材料性能下降。如绝缘层变脆、开裂，失去对导体的有效隔离，增加漏电、短路风险。
Long-term operation, temperature changes, electrical stress, etc., ofbusway will degrade the performance of insulating materials. For instance, the insulating layer becomes brittle and cracked, losing effective isolation from the conductor, which increases the risk of electric leakage and short circuits.
若母线槽处于潮湿环境，或因密封不良导致水汽进入，绝缘性能将大幅降低。水分会在绝缘层表面形成导电通道，引发漏电事故。
If thebusway is in a humid environment or water vapor enters due to poor sealing, the insulation performance will be significantly reduced. Moisture will form a conductive path on the surface of the insulating layer, triggering electric leakage accidents.
当实际负载电流超过母线槽额定电流，即发生过载。可能因设备增加、运行功率提升，或电力系统设计不合理，未充分考虑未来负载增长。过载时，母线槽发热加剧，温度过高会损坏绝缘层、缩短使用寿命，甚至引发火灾。
When the actual load current exceeds the rated current of thebusway, overload occurs. This may be caused by the addition of equipment, increased operating power, or unreasonable design of the power system that does not fully consider future load growth. During overload, thebusway heats up more severely. Excessive temperature will damage the insulating layer, shorten the service life, and even cause fires.
母线槽绝缘老化、受潮、机械损伤等，致使绝缘层破损，不同相导体间或导体与外壳间直接接触，产生强大短路电流，瞬间释放大量热量，损坏设备。
Aging, moisture, mechanical damage, etc., of thebusway insulation will lead to damage to the insulating layer, causing direct contact between conductors of different phases or between the conductor and the shell, generating a strong short-circuit current that releases a large amount of heat instantaneously and damages the equipment.
母线槽安装或维护时不慎遗留金属异物，或小动物进入母线槽，可能造成导体间短路。
Metal foreign objects left accidentally during the installation or maintenance of thebusway, or small animals entering thebusway, may cause short circuits between conductors.
