Unverified弱电箱内空间狭小散热差时不建议放大功率PoE或万兆交换机，长期高温会导致降速和寿命缩短，应选低功耗无风扇机型或加装散热87% similarUnverified购买摆放于弱电箱内的交换机需注意机身尺寸和散热：弱电箱空间封闭散热差，优先选低功耗无风扇薄型号，避免长期高温缩短寿命84% similarUnverified热过载继电器不能替代短路保护，它只防持续过载不防瞬间短路，回路必须另配熔断器或断路器；仅装热继电器不装短路保护是错误接线80% similarUnverified不建议为了美观选择尺寸刚好装满断路器的配电箱，散热不良会加速断路器老化并影响载流量，大功率密集回路应选带散热空间的大箱体79% similarUnverified散热贴只能扩散/传导热量，无法主动带走热量，若设备处于封闭无风环境(如塞进厚壳)贴纸效果有限，此时应优先选散热背夹或改善通风79% similar
