Technical field
A kind of ground wire installing port seal of the utility model is related to power system insulation, is that one kind is applied to power train
The system medium-and-large-sized distribution transformer aluminium of high pressure outdoor mounted（Copper）Row's formula outlet inspection earthing line installing port insulation box device, particularly
Insulation for the special hanging earthing conductor fixing point of cover lid Repair of Transformer.
Background technology
The outdoor main transformer of current power system by volume due to being limited, and outlet is mostly using relatively-stationary hard
Copper bar or aluminium row are as lead-out wire, and due to being made compact, safe distance all design comparisons between phase and phase are small.For anti-falling stop
Thing causes phase fault, and industry countermeasure is by outlet copper（Aluminium）Row is closed with isolating shrinkable formula rubber sheath.Main transformer is examined
Line requirement need to be mounted by repairing：Must be by the copper of closing（Aluminium）Arranging a 10cm or so mouth is used for hanging earthing conductor.But thus
Disagreed with countermeasure, while also increasing transformer makes the danger of cutting-out of voltage changer because foreign matter drops.
The insulation processing that fixing point is installed in some areas to main transformer outlet copper bar ground wire is to use to be more than copper bar（Including pyrocondensation
The rubber sleeve crossed）Rubber sheath（Physical form is just enclosed on ground connection mouth and is defined）, opposite side plastics after copper bar on the opening sleeve of side
Button or Plastic Bandage seal mouth, to reach the purpose insulated at copper bar opening.So to install ground wire bring it is very big tired
Difficulty, will be grounded with insulating bar or insulating bar mouth insulating boot and is moved on one side, due to being rubber cover to copper when installing ground wire
The space of row is little（Too big easily displacement is not in aperture position）In addition it is that the rubber sleeve with pyrocondensation on copper bar of rubber rubs
Wipe coefficient especially big, therefore move very difficult, ground wire recovers all to be difficult after removing.
