Problems solved by technology

Because the overall sealing of the switch cabinet is usually poor, the relative humidity in the cabinet is high, and condensation, water seepage and other adverse phenomena are prone to occur
The condensation phenomenon causes the QR code, nameplate and other marks on the surface of the terminal to be corroded by moisture, and the self-adhesive marks such as the QR code are easily corroded by moisture, and product information cannot be displayed normally, and cannot be scanned and identified normally, which affects the normal maintenance and use of the product
[0003] According to the requirements of industry standards, the protection level of most distributed DTU interval units is not higher than IP43, and condensation is prone to occur inside the terminal, which will cause equipment failure

Abstract

The invention discloses a shell applied to a distributed DTU interval unit. The shell comprises a display surface film, a panel, a control circuit board, a shell body, a sealing pressing plate and a support. The display surface film is tightly connected with the front side surface of the panel through an adhesive layer; the bracket is fixed on the back surface of the panel; the shell is buckled atthe outer part of the bracket; the control circuit board is arranged in a space between the panel and the shell and is used for realizing power distribution control; and the sealing pressing plate isfixed on the shell. The protection level can reach IP66, water vapor is effectively prevented from entering the terminal, condensation is avoided, and the reliability of the terminal is effectively improved.

Description

technical field [0001] The invention relates to the technical field of power distribution automation, in particular to a casing applied to a distributed DTU interval unit. Background technique [0002] In the field of intelligent distribution network, distributed DTU interval units are usually installed in outdoor switch cabinets. Because the overall sealing of the switch cabinet is usually poor, the relative humidity in the cabinet is high, and condensation, water seepage and other adverse phenomena are prone to occur. The condensation phenomenon causes the QR code, nameplate and other marks on the surface of the terminal to be corroded by moisture, and the self-adhesive marks such as the QR code are easily corroded by moisture, and product information cannot be displayed normally, and cannot be scanned and identified normally, which affects the normal maintenance and use of the product. [0003] According to the requirements of industry standards, the protection level of ...
