Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a moisture-proof power supply chassis for a relay station. Background Technique

[0002] A relay station is a radio station that is responsible for receiving and forwarding radio signals. After regenerating and amplifying the signals, it forwards them to the next relay station to ensure the quality of the transmitted signals. The relay station mainly consists of a power supply cabinet, an integrated cabinet, an access network cabinet, an interval frequency shift cabinet, an interval combination cabinet, a signal centralized monitoring cabinet, an electrical service supervision cabinet, etc. The stability of the power supply cabinet is directly related to whether the relay station system can operate stably for a long time.

[0003] After retrieval, the patent with the publication number CN219833454U discloses a moisture-proof power supply chassis for a relay station. Through the operation of the dehumidifying fan inside the dehumidifying box, the moisture inside the power supply chassis main body will enter the dehumidifying box through the dehumidifying pipe. After entering, the moisture can be processed by the first dehumidifying net. At the same time, when it is discharged from the bottom of the dehumidifying box, it will pass through the second dehumidifying net again for secondary dehumidification treatment, so as to achieve the purpose of efficiently dehumidifying the inside of the power supply chassis main body, avoiding damage to the power supply equipment inside the power supply chassis main body caused by moisture and affecting the normal use of the relay station.
