Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the structural representation of cable distribution device embodiment.
Among the figure: 1-cable distribution device static connection pedestal, 2-casing, 3-elbow cable joint, 4-leader cable, 5-main fixed contact, 6-quiet arc contact, 7-arc-extinguishing tube, 8-permanent magnet, 9-active contact, 10-moving arcing contact, 11-disjunction spring, 12-arcing contact compression spring, the 13-lead that is flexible coupling, 14-cable distribution device be dynamically connected pedestal, 15-armature, 16-operating grip, 17-branch cable.
Embodiment
Embodiment: this distribution box adopts the manufacturing of stainless steel casing, anticorrosion, protected against the effects of immersion, good airproof performance, and door locking mutually can not be opened simultaneously before and after the casing, guarantees maintenance and handling safety.The elbow cable joint, cable distribution device, fuse, lightning arrester are formed for the cordwood system type independent component, cable distribution device and all electrified bodies are all close with high-strength polyester material SMC and silicon rubber insulation envelope, can be according to user's needs, above the casing, below, and the rear into and out of line.
As shown in Figure 1, 2, 3, the outdoor high-voltage cable distribution box comprises leader cable 4 and the branch cable 17 in the casing, each branch cable end is connected with elbow cable joint 3 respectively, elbow cable joint stube cable coupler, the cable distribution device is by static connection pedestal 1 pedestal 14 that is dynamically connected of pegging graft, and the static connection base interior is connected with main fixed contact 5, and the base interior that is dynamically connected is connected with initiatively contact 9, initiatively contact connects the lead 13 that is flexible coupling, and the pedestal outer end that is dynamically connected is connected with operating grip 16.Cable distribution device, elbow cable periphery are by high-strength polyester material SMC and silicon rubber insulation sealing.
As shown in Figure 3, main fixed contact 5 ends connect quiet arc contact 6 and arc-extinguishing tube 7, and the cable distribution device pedestal that is dynamically connected has moving arcing contact 10, and socket disjunction spring 11 and arcing contact compression spring 12 on the moving arcing contact are formed blowout unit.The cable distribution device static connection pedestal and the base interior that is dynamically connected are equipped with permanent magnet 8 or armature 15 respectively.Initiatively contact 5 can be opposite each other raised type or indent formula with main fixed contact 9.
