Summary of the invention:
The purpose of this utility model is to provide a kind of underground type 10 kv cable splitter, and described this underground type 10 kv cable splitter will solve the technical problem that the fail safe of cable branch device is poor or result of use is undesirable in prior art in underground distribution net.
This underground type 10 kv cable splitter of the present utility model, comprise a casing, wherein, described casing is cuboid, the sidewall of casing is formed by steel plate or corrosion resistant plate, is perfused with insulating oil in casing, and the upper end sealing of casing is provided with a case lid, described case lid is provided with the high-voltage cable connector of two or more number, case lid is also provided with a high voltage load switch, a pressure relief valve and a cable connection bracket.
Further, the sidewall of casing and the surface of case lid are all coated with corrosion-inhibiting coating.
Further, connector shell and three-phase jointing is included all separately in high-voltage cable connector described in any one, described three-phase jointing is arranged in described connector shell, is perfused with dielectric, is provided with mechanical seal structure in connector shell in connector shell.
Further, described high voltage load switch is made up of two stations or four station oil-immersed load switchs.
Further, described cable connection bracket comprises retort stand, insulation crossbeam and cable anchor ear, and described cable anchor ear is arranged on described insulation crossbeam, and insulation crossbeam is arranged on described retort stand.
Further, utilize wire to pass through described high voltage load switch between described high-voltage cable connector and connect, described wire is positioned at casing.
Operation principle of the present utility model is: casing and case lid form all-sealed structure, utilize the wire in casing to be connected by high voltage load switch, realize cable branch between high-voltage cable connector; Insulating oil in casing can meet box house wiring insulating requirements and the requirement of on-load switch break-make arc extinguishing, and insulating oil can realize heat radiation.High-tension cable line adopts three-phase integratedization to plug and insulated enclosure joint, makes equipment not only safe and reliable but also compact structure.Each line and on-load switch lead-in wire all complete at box house, ensure that product meets IP68 requirement of shelter completely.When the pressure relief valve of case lid can realize fault, box house pressure discharges automatically, prevents casing from bursting.
Compared with prior art, its effect is actively with obvious to the utility model.The utility model utilizes casing and case lid to form all-sealed structure, the wire in casing is utilized to be connected by high voltage load switch between high-voltage cable connector, realize cable branch, each line and on-load switch lead-in wire all complete at box house, ensure that product meets IP68 requirement of shelter completely.Insulating oil in casing can meet box house wiring insulating requirements and the requirement of on-load switch break-make arc extinguishing, and insulating oil also can realize heat radiation.High-tension cable line adopts three-phase integratedization to plug and insulated enclosure joint, makes equipment not only safe and reliable but also compact structure.When the pressure relief valve of case lid can realize fault, box house pressure discharges automatically, prevents casing from bursting.The utility model compatibly descends the developing direction of distribution network technology, substantially improves the reliability that cable branch device or feeder pillar connect under the adverse circumstances of underground.
