Description

Block terminal with prevent condensation function

Technical Field

The utility model relates to an electrical technology field specifically is an anti-interference outdoor transformer case.

Background

A substation box is a box body of a place where voltage and current of electric energy are converted, concentrated, and distributed in an electric power system. The transformer cabinet is internally provided with a compact complete set of distribution equipment which is combined in one or more boxes according to a certain wiring scheme, such as switch equipment, a distribution transformer, a measuring instrument, a reactive compensation device and the like. With the continuous promotion of urbanization process and the continuous popularization of power equipment, the transformer box is widely used in indoor and outdoor places such as urban power grid transformation, residential districts, high-rise buildings, industrial and mining places, hotels, shopping malls, temporary power utilization facilities and the like. The transformer box is set up for protecting electronic components and ensuring the safety of pedestrians and residents.

Current block terminal need regularly cool down and the effect of dehumidification work to the block terminal when using, adopt the drier to adsorb vapor and play the effect of dehumidification usually, but this kind of mode consumption drier dosage is big, need often change the drier, use cost is high, secondly current block terminal is not good because the radiating effect, the short circuit phenomenon that produces because high temperature often can appear, the block terminal content is easy because the change condensation of temperature in the great region of temperature round the clock, make inside instrument and apparatus short circuit, cause the life-span of block terminal to shorten greatly.

Disclosure of Invention

The utility model aims at providing a block terminal with prevent condensation function takes as follows of scheme for realizing above-mentioned purpose:

a distribution box having a condensation prevention function, comprising: box, vent, heat extraction fan, drier layer, heating wire, photovoltaic module and photovoltaic battery, the top and the below of two sides of box all are equipped with the vent, and the heat extraction fan is installed outward to the vent, and except the equal cladding drier layer of ground, leave the gap between drier layer and the box inner wall in the box, laid the heating wire in the gap between drier layer and the box inner wall, photovoltaic module installs in the box top outside, and photovoltaic module is connected with the photovoltaic battery in the box, photovoltaic battery respectively with heat extraction fan and heating wire electric connection.

Furthermore, the desiccant layer is made of a PVC semipermeable membrane, and a silica gel desiccant is filled in the middle of the PVC semipermeable membrane.

Further, the vent is provided with a metal filter screen, and the mesh number of the metal filter screen is 1000-1500 meshes.

Furthermore, a box door of the box body is a drag door, and a guide rail is arranged below the box door.

The utility model has the advantages that:

(1) the utility model discloses a respectively set up the vent that has the filter screen and the heat extraction fan carries out the current conversion to the air in the box in the side top and the below of box, play the effect of full box cooling, solve the problem at heat extraction dead angle can appear in traditional single heat extraction fan to the filter screen can avoid impurity and dust to get into and cause the trouble in the box.

(2) The utility model discloses add in the box and establish the drier layer, the drier layer is made by the PVC pellicle, can see through water and vapor, and the moisture that silica gel drier can the adsorbed air is filled in the PVC pellicle, prevents to cause the trouble because the condensation that cold and hot production in turn is attached to on instrument and the circuit.

(3) The utility model discloses lay the heating wire between drier layer and box inner wall, the heating wire generates heat and can dry the silica gel drier that has adsorbed moisture gradually when circular telegram, leads the drier can cyclic utilization, reduces the number of times of changing the drier, reduce the cost.

(4) The utility model discloses a photovoltaic module and photovoltaic battery realize self-power supply, energy saving for heat extraction fan and heating wire power supply.
