Description

Technical Field

[0001] The present application relates to the technical field of cabinet equipment, and in particular to an outdoor integrated cabinet with AC and DC leakage protection. Background Art

[0002] In the construction of existing base stations, power supply equipment needs to be accommodated and installed in integrated cabinets and AC distribution boxes respectively.

[0003] The integrated cabinet is made of metal materials and is exposed to various climatic environments for a long time. Communication equipment, transmission equipment, power supply equipment, monitoring equipment, batteries and other supporting equipment can be installed inside it. The integrated cabinet can provide reliable mechanical and environmental protection for the normal operation of the internal equipment.

[0004] The three-phase AC distribution box used in the existing base station construction is mainly suitable for AC power distribution in mobile base stations, microwave stations and other communication rooms. To avoid leakage, the box adopts a fully sealed waterproof structure and the surface is sprayed with plastic. High-quality air switches are used inside, which have good overcurrent and overheating protection. Three-phase four-wire power supply (plus protective ground wire) and high-energy lightning arresters are installed to protect the power supply from lightning and surges. A three-phase standby switch, two single-phase switches and power sockets are reserved in the box for expansion needs.

[0005] In the existing outdoor base station construction, AC distribution boxes are mostly installed on outdoor cement platforms using special brackets close to outdoor integrated cabinets. The relevant cables are laid through hot-dip galvanized steel pipes, first out of the AC distribution box, and then routed from the bottom of the distribution box and outdoor integrated cabinet to enter the outdoor integrated cabinet.

[0006] However, the existing structure of outdoor base station power distribution equipment has the following problems:

[0007] In the actual construction process, since the integrated cabinet and AC distribution box are completed by different construction units, there are usually irregularities such as the AC distribution box is not installed close to the outdoor integrated cabinet, the installation direction is reversed, etc. In order to ensure the mutual electrical connection between the components in the integrated cabinet and the AC distribution box, after installation errors, the number of cables needs to be increased, resulting in cable leakage, which is not only unsightly, but also increases the safety hazards caused by cable leakage.

[0008] The main safety hazards are as follows: After the AC distribution box is built away from the cabinet, the AC cable needs to be led out from the AC distribution box, and then routed to the integrated cabinet from the outside. Some AC cables are not constructed in a standardized manner, and steel pipes are not strictly used to lead down or buried cables, which increases the probability of electric shock and other safety accidents when pedestrians pass by the base station. At the same time, the lightning protection grounding of the AC cable is not done or the grounding is poor, which increases the probability of electric shock safety accidents when pedestrians pass by.

[0009] The AC distribution box is installed with an angle steel bracket. If the construction is not standardized, the angle steel bracket will not be firmly fixed to the ground, causing the AC distribution box to overturn and lie upside down on the ground. When pedestrians pass by, it may cause safety accidents such as electric shock.

[0010] CN 201621102606.7 discloses a side wall embedded distribution box structure, in which a distribution box is installed on the side wall of an integrated cabinet. When some problems occur in the device, they can be corrected by adjusting the side wall distribution box. However, the distribution box of this structure is only connected to the integrated cabinet through a sealing strip. When used outdoors for a long time, the waterproof and weather resistance performance is poor, and the risk of water ingress is high.

[0011] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in the field.
