绝缘导线过电压保护器安装工艺规范

1、绝缘导线应放在柱式瓶中间凹槽内(不得放置在侧槽内)。

1, insulation wire should be in the middle of the pillar type bottle and the slots (slot) shall not be placed on the side.

2、过电压保护区不锈钢引流环与绝缘导线线芯之间的间隙要控制在100±5mm范围内,引流环与绝缘子之间的间隙必须均匀,控制在25±5mm范围内。

2, overvoltage reserve stainless steel drainage clearance between ring and insulated conductor wire core to control within the scope of the 100 + / - 5 mm, drainage of the clearance between the ring and insulator must be uniform and controlled in the range of 25 + / - 5 mm.

3、对于不剥除绝缘层的架空均匀线路,三相引流环圆弧应朝同一方向外置,以免引流环之间间隔过小,影响架空线路绝缘配合。

3, are not uniform removal of insulation overhead line, the three-phase flow loop outside the arc should be in the same direction, in order to avoid the drainage intervals between ring is too small, affect the overhead line insulation coordination.

4、安装前过电压保护器应采用不低于5000V的兆欧表进行绝缘电阻测试,在干燥的情况下,绝缘电阻不低于1000兆欧。

4, before the installation of over-voltage protector should be not less than 5000 v megohmmeter for insulation resistance testing, in the case of drying, the insulation resistance is not less than 1000 ohms.
