Introduction

GB/T 19183 "Outdoor enclosures for mechanical structures of electrical and electronic equipment" is for outdoor electrical and electronic equipment used in places without weather protection.

It is designed for electronic equipment casing and is intended to consist of three parts.

--- Part 1: Design guidelines. The purpose is to provide a general outline of the requirements for the use of enclosures in outdoor non-weather-protected locations.

specification.

--- Part 2: Coordinated dimensions. The purpose is to ensure that the external dimensions of the outdoor enclosure are coordinated by specifying the internal and external dimensions of the outdoor enclosure.

and consistency of internal connection dimensions.

--- Part 3: Environmental requirements, tests and safety requirements. The purpose is to meet the storage, the requirements for transportation and final installation conditions establish the basic environmental performance standards for outdoor enclosure compliance.

With the continuous development of electrical and electronic equipment, outdoor enclosures are increasingly used.

The general guidelines developed in other parts of the Outdoor Enclosures series provide more complete design guidance for outdoor enclosures and accelerate their in-depth develop.

1 Scope

This document contains guidelines for the design of outdoor enclosures for electrical and electronic equipment and is applicable to a wide range of mechanical, electromechanical, and electrical installations using modular design.

Sub-device.

The purpose of this document is to.

--- Provides a general specification focusing on outdoor application requirements for enclosures used in fixed locations without weather protection;

---Achieve product integrity in outdoor conditions and simplify product selection for outdoor enclosures from different suppliers.

These enclosures can house any equipment and protect equipment installed outdoors from harmful environmental influences. The equipment installed can be but not limited to subracks or enclosures that comply with IEC 60917 series or IEC 60297 series. A typical outdoor enclosure is shown in Figure 1.
