Composite Insulator Hydrophobicity Testing Machine For On-line Detection Of The Hydrophobicity

DX8436 Composite Insulator Hydrophobicity Tester

1. Scope of application:

Composite insulator hydrophobic live detector is a new type of insulator hydrophobic online detection. It is suitable for on-line detection of the hydrophobicity of composite insulators of transmission lines of 110kV and above voltage levels, and is also suitable for the hydrophobicity detection experiments and factory testing of various composite insulators and silicone rubbers, and is also suitable for the hydrophobicity detection of RTV spraying materials of magnetic insulators.

2. Detection principle:

The hydrophobic state of composite insulators is judged according to the water spray classification method of the Swedish Transmission Research Institute (STRI). Based on advanced digital image processing technology, the hydrophobic state of composite insulators is objectively judged by extracting gray information such as information entropy, seed rate, and mean spectral amplitude of hydrophobic images, as well as the shape coefficient and area percentage of water droplets or water traces.

3. Compliance with standards:

It meets the requirements of the test standard of DL/T864-201 "Guidelines for the Use of Composite Insulators for AC Overhead Lines with Nominal Voltage Higher than 1000V".

4. Product function:

1. Detect the hydrophobicity of various composite insulators with live electricity

2. Test the hydrophobicity of silicone rubber and RTV spraying materials

3. Automatic and accurate analysis of hydrophobic levels
