Introduction
This document is compiled based on the research results of discharge ultraviolet detection conducted by relevant units on the substation site and in the laboratory.
The methods and criteria presented in this document are derived from observed examples in field and laboratory tests. Taking into account the environmental parameters and instrument models,
Due to differences in versions, different models and batches of ultraviolet imagers may not observe completely consistent discharge phenomena in the same environment.
Since substations and transmission lines are different in terms of equipment, defect types, and importance levels, etc., the detection strips for ultraviolet detection in substations
There are some differences from transmission lines in terms of components, detection methods, defect classification and processing, and detection cycle.
GB/T 37141 is divided into two parts, including.
--- Part 1.Substation. The purpose is to provide high-altitude substation corona and arc ultraviolet imaging detection, defect evaluation, etc.
method and basis.
--- Part 2.Transmission lines. The purpose is to provide corona and arc ultraviolet imaging detection and defect evaluation for transmission lines in high altitude areas
Provide methods and basis.
