Description
Technical field
The present invention relates to the remaining cable frame (insulation fitting) of one kind insulation, it is mainly used in OPGW (OPGW) high pressure
Optical communication field in transmission line of electricity, you can lightning-arrest, can meet the optical cable storage in ultra-high-tension power transmission line again.
Background technology
Ground wire can use the short circuit current flow in the method reduction OPGW of increase earth point when insulating., in having OPGW circuits
OPGW and shunt line is asked to be grounded by tower, to accelerate the decay of short circuit current flow.And in long transmission line, what is had will be far from the portion of transformer station
Divide ground wire, using insulation against ground --- reduce power consumption.When in insulating segment short circuit occurs for circuit, short circuit current flow only passes through 1
OPGW returns to electric substation, and now the short circuit current flow in OPGW can increase suddenly, it is possible to more than permissible value.In order to reduce in OPGW
Electric current, in the case where not changing the model and length of shunt line, can use close to become transmission tower at Ground wire with insulation ocver increase
The method of several earth points, solves OPGE thermally-stabilised problem.Insulating method originally is to completely cut off electric current using insulation rubber
Conduction, due to insulation rubber be tightly attached to by steel band anchor ear on electric pole, easily there is the phenomenon of ageing of rubber, cause insulation
Hydraulic performance decline adds accident potential and personnel's intensity, it is necessary to regularly replace.
