Description
Technical field
The present invention relates to a kind of cable connecting arrangement and installation method, the transition joint of specifically a kind of middle pressure multicore cable is with its installation method.
Background technology
Along with the development of China's power construction, electricity needs constantly soaring, in order to reduce the power transmission and transformation cost and to reduce the power transmission and distribution loss, middle voltage source enters directly that to carry out power distribution with electrfic centre be very general.The medium-pressure power cable demand is increasing, and is to need two or many power cables butt joints setting up electrical network, then according to the characteristic of the construction of cable, at joint each structure sheaf of cable is recovered, to guarantee the key property of cable, therefore, transition joint seems in this problem and is even more important.In the prior art, in the processing of three-core cable butt joint, all be that three heart yearns of the free-hand cable that stripping is handled well of technical staff strut, then according to dimensional requirement difference stripping heart yearn, refill transition joint, hold with water blocking tape and armoring tape, thus the butt joint of realization three-core cable.And in the prior art, this free-hand mode that struts heart yearn, the unordered mixed and disorderly distribution of heart yearn after often causing strutting, flexural deformation and swollen outwardly radially opening, and the unordered mixed and disorderly distribution of heart yearn causes the inequalities that distribute such as the electric field in the transition joint easily, and the flexural deformation of heart yearn and swollen outwardly radially opening, not only cause the bending of inner each layer of heart yearn to be moved easily with relative, thereby cause and the gap occurs between the cable core interior layer and cause the joint internal discharge easily, simultaneously, because heart yearn is harder, after installing transition joint on the heart yearn of butt joint, heart yearn still has the outwards swollen trend of opening, so cause stress cone and internal shield generation serious deformation in the transition joint to be damaged easily, has certain potential safety hazard.A kind of 15KV and following three core oils that propose as Chinese patent literature CN2137829Y soak the transition joint of paper insulation power cable resin-cast, this three core oil soaks the transition joint of paper insulation power cable resin-cast and is made up of housing and internal structure, cloth intercoil connection in the inner walls plating screen, screen.Open the sprue gate on the housing, exhaust outlet, air slot.Card insulation support plate in the housing, with three cores support separate guarantee alternate and.Respectively wrap viscosity oil resistant clay on insulation and the tape insulation mutually, skin is tied tight with the alkali glass silk ribbon.Cast oil resistant insulating synthetic resin pouring agent in the housing.
In addition, in the prior art, imperfection is gone back in the processing that holds to transition joint, be mainly reflected in: all heart yearns of cable are after loading onto transition joint respectively, external application water blocking tape and armoring tape one circle circle carry out spiral hold make it to tie into a branch of, make the cable butting place of holding be irregular triangular shape, and the outline of triangular shape is when being subjected to the weight extruding, hold band and occur groove easily with the lap-joint that holds band, caused and held surface ponding easily, thereby cause the inner infiltration easily of cable butting, in the useful life that this has reduced transition joint undoubtedly, be easy to cause the generation of cable line fault.
Summary of the invention
For this reason, technical problem to be solved by this invention be three-core cable transition joint in the prior art heart yearn separately be to cause the unordered mixed and disorderly distribution of heart yearn by free-hand finishing, flexural deformation and swollen outwardly radially opening, thereby cause stress cone and internal shield generation gross distortion in the transition joint to damage, and the bending of inner each layer of cable is moved with relative, thereby cause the problem that the gap occurs between the cable interior layer and cause the joint internal discharge easily, provide a kind of and can divide equally heart yearn, and in dividing equally the process of heart yearn, can prevent swollen multicore cable transition joint and the installation method of opening thereof of heart yearn distortion.
