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.
