日常设备使用中有不少因素可能对配电箱性能产生影响,比如日常的维护措施是否科学合理,空气中的灰尘,使用环境的温度,散热是否良好以及设备自身的震动等都有可能影响设备性能,影响仿威图机柜性能的主要因素。
There are many factors in the daily use of equipment may affect the performance of the distribution box, such as whether the daily maintenance measures are scientific and reasonable, dust in the air, the temperature of the use environment, heat dissipation is good and the vibration of the equipment itself may affect the performance of the equipment, the main factors affecting the performance of the imitation Weichart cabinet.
按国标设计和制造的电气成套设备运行时周围环境温度的上限值不应超过40℃,而盛夏暴露在烈日中的户外配电柜,由于太阳光的直射、水泥地面热量的反射以及柜内设备自身产生的热量,有时户外配电柜内的温度竟超过60℃。
The upper limit of ambient temperature of complete electrical equipment designed and manufactured according to national standards should not exceed 40℃ when it is running. However, the outdoor power distribution cabinet exposed in the hot sun in summer sometimes has a temperature of more than 60℃ due to direct sunlight, heat reflection from the cement floor and heat generated by the equipment in the cabinet.
电器触头因温度过高而增加接触电阻,接触电阻增加又加剧发热,如此恶性循环终导致触头烧坏;同时温度过高还会影响户外配电柜保护性能的稳定性、动作的可靠性、计量的准确性。
The electrical contact increases the contact resistance due to high temperature, and the increase of contact resistance increases the heating, so the vicious cycle eventually leads to the contact burn out; At the same time, the high temperature will affect the stability of outdoor PDC protection performance, reliability of operation, and accuracy of measurement.
设备的防尘:防尘是这类设备使用过程中须要注意的事项,机箱长时间积聚灰尘会大大降低散热功能,导致风扇等部件无法正常运转,从而产生一定的噪音。因此除了在设备使用中采取一定的防尘措施外,对于设备机箱的日常清理也是比较重要的。
Dust prevention: Pay attention to dust prevention when using the device. Dust accumulation in a shelf for a long time greatly reduces the heat dissipation function and causes the abnormal operation of components such as fans, which causes certain noise. Therefore, in addition to taking certain dust-proof measures in the use of the device, it is also important to clean the device chassis daily.
设备的散热情况:配电箱是否能够正常运行,与设备的散热情况有较为直接的影响。如果散热情况较差可能导致设备瘫痪无法正常运行。
Heat dissipation of the device: The normal operation of the power distribution box directly affects the heat dissipation of the device. If the heat dissipation is poor, the device may break down and cannot run normally.
设备产生的振动噪音:设备运行中出现的噪音主要是由于机箱的硬度及箱体的连接方式的不同导致的。如果材料较薄,导致机箱不坚固,在使用中与内置的电子设备形成共振产生噪音。
Vibration noise generated by the equipment: The noise generated during the operation of the equipment is mainly caused by the hardness of the box and the connection mode of the box. If the material is thin, the chassis is not solid, in use with the built-in electronic equipment to generate resonance noise.
还可能导致机箱变形使板卡死在上面。板材过于轻薄的机箱机柜强度不足,容易变形,进而损伤硬件,同时由于其他零部件的共振出现噪音,造成配电箱的性能受到影响。
In addition, the chassis may be deformed and the board may be stuck on it. The chassis with too thin plates is weak in strength and prone to deformation, which damages the hardware. At the same time, the performance of the distribution box is affected due to the resonance noise of other parts.
