Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] see Figure 1-5 , the present invention provides a technical solution: a high-current isolated-phase closed busbar, including a line pipe 1, the top and bottom of the line pipe 1 are connected with a fixed box 2, and both sides of the inner cavity of the fixed box 2 are fixedly installed with a support rod 3, and a snap ring 4 is fixedly installed between the two poles 3, and a bus bar 5 is fixedly installed in the snap ring 4. The setting of the snap r...

The invention discloses a large-current phase-isolated enclosed bus, which comprises a wire tube. The top part and the bottom part of the wire tube are both communicated with fixing boxes; two sides of the inner cavity of each fixing box are fixedly provided with supporting rods; a clamping ring is fixedly arranged between the two supporting rods; a busbar is fixedly arranged inside the clamping ring; a wire core is arranged in the busbar; the bottom part of the inner cavity of the fixing box is communicated with a wiring tube; two sides of the inner cavity of the wiring tube are fixedly provided with spring rods; the opposite sides of the spring rods are fixedly provided with a clamping piece; and a conductive piece is fixedly arranged inside the wiring tube and located below the spring rods. According to the large-current phase-isolated enclosed bus, through improvement on the wire tube and the wiring tube, effects of enabling good contact at the busbar joint and preventing drawing of the busbar are achieved, normal use of the busbar is thus kept, the normal use of the busbar is not influenced even under effects of an external force, and the service life of the busbar is greatlyprolonged.
Description
technical field [0001] The invention relates to the technical field of busbars, in particular to a high-current isolated-phase enclosed busbar. Background technique [0002] Enclosed busbars include phase-separated enclosed busbars, common-box enclosed busbars and cable busbars, which are widely used in power plants, substations, industrial and civil power supply leads. A large current transmission device for branch circuits in factories. [0003] The conductors and shells of the isolated-phase closed busbar are rolled and welded by aluminum plates, which can reduce grounding faults and avoid short-circuit between phases. The isolated-phase closed busbar can eliminate the grounding fault caused by external moisture, dust and foreign objects because of the shell protection. The occurrence of phase-to-phase short circuit facilitates the elimination of steel structure heating. The phase-separated closed busbar adopts shell shielding to fundamentally solve the problem of steel ...
