Abstract

The invention relates to an IP44 protection structure of a JP cabinet. An IP44 protection structure of a JP cabinet, which includes a JP cabinet body; outer shutters and inner shutters are arranged on the side plates on both sides of the JP cabinet body; the window holes of the outer shutters and the inner shutters are in a misplaced arrangement; The inner side of the louvers is provided with a stainless steel mesh; the bottom of the JP cabinet body is provided with a matrix orifice; the upper side of the matrix orifice is also provided with a stainless steel mesh. The IP44 protection structure of the JP cabinet of the present invention has low processing cost, simple structure and parts processing, adopts the misplaced arrangement of the window holes of the double louver to block the direction of external water droplets, and sets the stainless steel mesh inside, which not only meets the IP44 protection level sealing of the JP cabinet Strict and can meet the temperature rise requirements.

Description

technical field [0001] The invention relates to the field of 10kV pole-mounted transformer platform complete sets, in particular to an IP44 protection structure of a JP cabinet. Background technique [0002] At present, the transformation of urban and rural power grids of the State Grid uses a large number of pole-mounted transformer sets across the country, and the JP cabinet is an important part of the device. In the typical design of the original State Grid, the protection level of the JP cabinet is required to reach IP44 (the second 4 represents splash water resistance). The specific plan is to punch two rows of louvers in the height direction on both sides of the cabinet. During repeated tests or random inspections, some water will enter the side louvers, which cannot meet the requirements of IP44 protection level. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a JP cabinet IP44 protection s...
