33kV lightning rod mainly made of zinc oxide, including power plant type, distribution type and combination type (such as integrated design of 33kV combined lightning rod and fuse), suitable for lightning surge and continuous current power frequency protection in transmission and distribution systems.
Execution standard:It must comply with the international standard IEC60099-4, and some models must be adapted to regional grid specifications, emphasizing compatibility with system voltage and short circuit power
Main component:Zinc oxide valve plate as core, with non-linear current-voltage characteristics, response time ≤ 25ns, and current capacity meeting 33kV system short-circuit current requirements.
Shell material:Silicone rubber composite material, strong weather resistance (-40℃~+40℃), some combination models integrate fuses to achieve matched overcurrent and overvoltage protection.
Supporting structure:The fixed frame is screw fastened and the connection terminals are integrated into the fuse body during installation, which improves mechanical stability
Main functions:
Lightning protection of 33 kV power transmission and distribution lines and substation equipment, reducing the risk of lightning outages and breakdown of equipment insulation; Continuous power frequency current cutting is used to protect the safe operation of equipment such as transformers and switchgear.
