结构简介CONSTRUCTURE IN TRODUCTION
避雷器由非线性电阻片，硅橡胶外套及两端金具组成，如图1所示。
非线性电阻片和加强纤维复合结构整体地封装在硅橡胶的外套中，并在每个结合部都涂有密封胶，使其形成一个坚固的整体。避雷器内部不含空气隙，由于电阻片具有优异的非线性伏安特性和良好的陡波响应特性，可将过电压限制在较低的水平，从而对电器设备的绝缘提供可靠的保护。作为外绝缘的硅橡胶外套与瓷套相比，不但重量轻，不易碎，而且耐污性能优异，没有爆炸的危险，用它制成的避雷器是一种十分理想的保护电器。 |
The MOA is composed of the non-linear resistors
,silicone rubber housing and metal fittings as shown
in fig.1.
As the non-linear resistor and the strengthened
fibre composite structure are totally enclosed in
silicone rubber housing and the sealing glue is smeared
on every connected section,so the arrester is formed
a strong stick.There is no any air crack in the MOA,the
non-linear resistor due to the inherent superior V-I
characteristics and steepwave response can suppress
overvoltages to a relative low level,thus providing
a reliable protection for insulation of electrical
apparatus.
The silicone housing as extra-insulation compared
with porcelain housing has more special advantages
as following:
*small in size and light in weight
*easy to install and hard to damage during the transportation
*excellent function of anti-pollution
*no damage of exploding and combustion
*The MOA mode of silicone housing is a very ideal
to protact electrical apparatus. |
