Embodiment 2

[0039] Such as Figure 1-8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the curved processing frame 56 includes a filter plate 561 and an outer moisture-absorbing plate 562, and the ends of the filter plate 561 and the outer moisture-absorbing plate 562 Through the detachable connection provided with the connecting beam 7, the outer moisture-absorbing plate 562 is close to the circulation groove 2 opened on the side of the distribution box 1, which can effectively dehumidify the air entering the distribution box 1 from the external environment.

[0040] Further, the top and bottom of the inner surface of the filter plate 561 are provided with a first elastic frame 8, and the inner side of the first elastic frame 8 is fixedly connected with the inner surface of the filter plate 561 by being provided with an outer transmission rod 9, and the outer moisture-absorbing plate 562 The top and bottom of the inner surface of t...

Embodiment 3

[0042] Such as Figure 1-8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the inner top and bottom of the filter plate 561 and the outer moisture-absorbing plate 562 are movably connected with arc-shaped leaves 13 through a connecting frame, The curved leaves 13 are symmetrically arranged. The curved leaves 13 all include metal cooling blocks 131 and deodorizing plates 132. The metal cooling blocks 131 are provided with deodorizing plates 132 near the side of the filter plate 561. The metal cooling blocks 131 and The deodorizing plate 132 adopts sodium-potassium alloy and bamboo charcoal plate as raw materials respectively, which can effectively cool and deodorize the air passing through the filter plate 561 and entering the inside of the filter plate 561 and the outer moisture-absorbing plate 562.

[0043] Further, the surface of the dehumidification plate 51 is uniformly provided with a rectangular groove 14, and the ...

Abstract

The invention discloses a dehumidification device for a power distribution box, and relates to the technical field of power distribution boxes. The dehumidification device comprises a power distribution box body and a circulation groove formed in the right side of the power distribution box body, a movable sealing door is arranged on the front side of the power distribution box body, a connecting arm is arranged at the bottom of an inner cavity of the power distribution box body and close to the right side, a dehumidification mechanism is arranged on the inner side of the connecting arm, a flow guide mechanism is arranged on the right side of the inner cavity of the power distribution box body and located on the right side of the dehumidification mechanism, and the dehumidification mechanism comprises a dehumidification plate, an outer protection frame, a fixing rod, a spring and an arc-shaped treatment frame. According to the invention, dust carried in the air can be adhered while the air in the power distribution box body is rapidly dried and dehumidified, and the air in the power distribution box can be effectively cooled, deodorized and purified; meanwhile, the situation that the humidity of air entering the power distribution box body from external environment circulation is high, and consequently electric elements in the power distribution box body are affected is effectively avoided, and dust attached to the surface of a filter plate can be collected and treated in a centralized mode.

Description

technical field [0001] The invention relates to the technical field of distribution box protection, in particular to a dehumidification device for a distribution box. Background technique [0002] Distribution box The distribution box is a general circuit distribution box for all users to use electricity. It assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Constitutes a low-voltage power distribution device. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for deviations from normal wo...
