Communication cabinet with overcurrent protection function

Abstract

The invention discloses a communication cabinet with an overcurrent protection function. The communication cabinet comprises a press contact switch, a press plate, an upright post, a heating net, a first heat radiation sheet, spring posts, an arc-shaped top plate, an overload protector, a condensing pipe, a refrigeration block, a condensing box, a condensing box installing plate, electromagnetic valves, a three-way pipe, a fan, a square heating pipe, a heating wire, an air outlet joint, outer plates, inner plates, a temperature and humidity sensor, article placing plates, a heat radiation fan,reinforcing posts, cavities, heat radiation pipes, a lightning protector, a cabinet body and a cabinet door. The communication cabinet with overcurrent protection function comprises a heat radiationdrying mechanism; the heat radiation effect is relatively good; the communication cabinet is applicable to cabinet bodies with greater volume; the communication cabinet with the overcurrent protectionfunction comprises a cabinet top mechanism; in snowy days in winter, when snow accumulated on the top plate of the cabinet top mechanism is much, the press contact switch can be closed, so that the heating net in the arc-shaped top plate works; when the heating net works, accumulated snow on the arc-shaped top plate thaw; the occurrence of the snow accumulation condition on the top of the cabinetbody is reduced; the occurrence of the condition that the cabinet body collapses under the pressure of the accumulated snow is favorably avoided.

Description

technical field [0001] The invention relates to a communication cabinet, in particular to a communication cabinet with overvoltage protection, belonging to the technical field of communication cabinet applications. Background technique [0002] Communication cabinet refers to the cabinet that is directly under the influence of natural climate, made of metal or non-metal materials, and does not allow unauthorized operators to enter and operate. It provides an outdoor physical working environment and security system for wireless communication sites or wired network site workstations. The equipment is suitable for installation in outdoor environments, such as roadsides, parks, roofs, mountainous areas, and flat ground. Base station equipment, power supply equipment, batteries, temperature control equipment, transmission equipment and other supporting equipment can be installed in the cabinet or for the above equipment Reserve the installation space and provide reliable mechanic...

AI Technical Summary

Problems solved by technology

[0003] Existing communication cabinets often use air duct heat dissipation and semiconductor heat dissipation to dissipate heat inside the cabinet. The structure of the air duct heat dissipation is complex, and the heat dissipation effect is average. The semiconductor heat dissipation method cannot dissipate heat for a slightly larger cabinet. , once the volume of the cabinet is large, the heat dissipation capacity will be greatly reduced, and there are certain deficiencies, and most of the existing communication cabinets cannot dehumidify the interior, and condensation is prone to occur inside, which not only easily corrodes the equipment installed inside, but also And there is a certain threat to the operation safety of the equipment. At the same time, in winter, a large amount of snow is likely to be generated on the top of the cabinet. If it is not cleared in time, the cabinet is easily crushed by the snow, and there are certain shortcomings.
