Abstract
The utility model relates to a transition connector of resin-cast for three-core power cable under 15KV, composed of a casing and an internal structure. Metallic shielding layer is coated on the internal wall of the casing, and gap bridge wires are arranged inside the shielding layer; the casing is provided with a pouring opening, an air exhaust opening and an air guiding slot; the casing is provided with an insulation supporting board which separates a three-wire core in a supporting mode; oil blocking connection tubes block an oil circuit, and the surface of each connection tube is coated with a semiconductive belt; on the section of an oil paper side, each phase insulation is coated with an oil resistant insulating adhesive tape and an adhesive oil resistant cement; on the section of a rubber plastic side, the breaking point of each wire core shielding is coated with the semiconductive belt, the shielding layer, stress control belt, etc. The utility model is an ideal transition connector of the casing, which is poured with oil resistant insulation synthetic resin casting agents.
Description
The utility model belongs to the power equipment class, a kind of specifically middle connection device that is used for the power cable transmission line.
Mainly layering is wrapped at the scene forms by the workmen for existing three core power cable transition joints, at the wrapped alkali-free glass silk ribbon that scribbles epoxide-resin glue of oilpaper side, at wrapped stress control belt of crosslinked side and electro-insulating rubber band, when around to certain thickness, set metal silk screen, installation plastics or metal shell, infusion epoxy resin fluid sealant or pitch glue.Making transition joint like this requires the workmen to have skilled technical ability, labour intensity is big, working procedure is numerous and diverse, insulation is exposed in the air time and longly very easily makes moist the filling temperature height of the reaction temperature of epoxy glue or pitch glue, not only contaminated environment, infringement workmen's health, and impair insulation and structure, so that can not guarantee construction quality, rate of failure is higher.
The purpose of this utility model provides a kind of novel three core power cable transition joints.Adopt this joint, do not need workmen's site operation, and can directly adopt, thereby improve execution conditions, reduce labour intensity, can guarantee construction quality and useful life, protection environment and workmen's health.
The purpose of this utility model realizes that in the following manner 15KV and following three core power cable resin-cast transition joints are made up of housing 1 and internal structure.Housing 1 is made up of two parts up and down that inwall is coated with metal screen layer, cloth intercoil connection 7 on the metal screen layer 6.Have exhaust outlet 3 on the housing 1, seal cover 4 is established on mouthful in air slot 5, sprue gate 2.Card has two insulation support plates 19 that three cores are separated in the housing.At the interlude of two supporting brackets 19, stifled oil pipe 11 is taken over surperficial wrapped semi-conductive tape 12 with the oil circuit blocking-up at each.Oilpaper side section 9 in supporting bracket 19 outsides, each insulate mutually and goes up wrapped oil resistant insulating rubber strip 13, on lead dissecting port 14 and tape insulation 15, overlap with viscosity oil resistant clay 16 bag apple heads and with oil resistant adhesive tape 13, skin is tied tight with alkali-free glass silk ribbon 17, rubber side section 10 in another supporting bracket 19 outsides, each core shielding is cut-off and is located from inside to outside lapped insulation layer, semi-conductive layer, metal screen layer, the outer wrapped stress control belt 18 of metal screen layer.Annotate oil resistant insulating synthetic resin pouring agent in the housing.
The utility model content is described in detail in detail with reference to the accompanying drawings.
Fig. 1 the utility model structural representation
Fig. 2 insulation support plate 19 separates view with core
With reference to accompanying drawing, have exhaust outlet 3, air slot 5, sprue gate 2 on the injection-moulded housing 1, establish seal cover 4 on mouthful.Inner walls is the metal screen layer of electroplating or vacuum coating forms 6.Set bolt 8 weaves intercoil connection 7 with copper wire and is fixed on the housing 1, and larynx hoop 20 is tightly pricked it on rubber side section cable sheath, metal screen layer and armour, to guarantee the fault current circulation.Card two windmill shape insulation support plates 19 in the housing 1, with three cores separately come with guarantee alternate with mutually---separated distance between ground.Oilpaper side section 9 in a supporting bracket 19 outsides, each mutually insulation go up wrapped oil resistant insulating rubber self-adhesive tape 13 and wrap three bifurcation places to oil paper cable, overlap with viscosity oil resistant clay 16 bag apple heads and with oil resistant adhesive tape 13 on lead dissecting port 14 and tape insulation 15, skin is tied tight with the alkali-free glass silk ribbon and is formed the oil removal layer.Rubber side section in another supporting bracket 19 outsides, each cable core shielding is cut-off and is located from inside to outside lapped insulation layer, semi-conductive layer, metal screen layer, the outer wrapped stress control belt 18 of metal screen layer is to reduce the electric field of shield end.The two housings commissure is established hasp, catching groove 21, plating screen in the catching groove 21.The two housings part of closing, the shielding between last lower house just connect to be finished by the hasp and the coat of metal.Housing two ends and cable jacket adjoin the wrapped self-adhesive rubber band 22 in position, run off to prevent pouring agent.Pour into a mould oil resistant insulating synthetic resin pouring agent by sprue gate 2 in housing, air is discharged from exhaust outlet 3 through air slot 5 in the shell.Water fill with after, cover seal cover 4, promptly can be used as three core power cable transition joints through 2 hours behind the normal temperature gel and use.
The utility model does not need site operation, and is easy to use laborsaving, safe and reliable, is the transition joint device of desirable power cable transmission line.
