The polymeric housed metal oxide surge arrester

 

Summarize:

  The metal oxide surge arrester(MOA)is the most advanced over-voltage protector in the world. The metal oxide varistors(MOV),as the core organ, made under Japanese technology license. It have good response to steep front surge, excellent volt-ampere characteristics and high discharge capability, which provides a very consistent protection merit at steep front surge, lightning surge and switching surge, and enhances protective capability.
  The polymeric house, as a new generation of insulation, is characterized by small size, light weight, high strength, resistant to heavy pollution and free from cleaning maintenance.
    The product has been confirms by the Chinese national center for quality supervision and test of insulators and surge arresters. The technical performance of the product conforms to IEC 60099-4 standard technical requirements. 
 
Designation of type letters:
 
Condition of use:
1、            The ambient air temperatures is no higher than +40℃, no lower than -40℃.
2、            The altitude above sea level does not exceed 2000m.
3、            AC system frequency is 50Hz or 60Hz.
4、            AC voltage brought to bear on arrester for a long time does not exceed arrester’s continuous operating voltage.

The brief introduction of an arrester disconnector

   Every polymeric housed MOA puts up the disconnector. The disconnector is equipped with the insulation base. The top bolt of disconnector is directly connected with the bottom of MOA, the below bolt is connected with ground lead.
  The disconnector shall break away automatically at the fault current while the MOA failure under the abnormal conditions, and the failed MOA will be separated.
  The figure shows the product’s operation. The dotted line in the figure shows the situation of the grounding part’s disconnection while the disconnector operation.

Note: The last “L” in the designation means the disconnector. Such as YH10W-24L means that the disconnector has be equipped in the MOA of YH10W-24. If the disconnector isn’t equipped, the “L” no appear.
