Abstract
The utility model provides an adjustable shell telescopic structure for an isolated-phase bus and is characterized by being simple in structure, convenient and practical. The adjustable shell telescopic structure for an isolated-phase bus comprises a connecting plate and a telescopic joint; two ends of the telescopic joint are respectively connected with one end of the connecting plate; and the other end of the connecting plate is connected with a bus shell. The telescopic joint is a hollow and tubular structure; the center of the telescopic joint is an arc-shaped convex; and two ends of the telescopic joint are provided with a plurality of grooves.
Description
Technical field
The utility model relates to a kind of isolated-phase enclosed bus, is specifically related to adjustable shell stretching structure for a kind of isolated-phase enclosed bus, belongs to enclosed busbar manufacturing technology field.
Background technology
Existing phase-isolated closed bus conductor connection is mainly formed by the aluminium foil press process, then through deep processing, forms, and generally aluminium foil and connecting plate, consists of.During isolated-phase enclosed bus work, during variations in temperature, the severe stress that bus shell expands with heat and contract with cold and causes, this kind of structure can not be adjusted the severe stress of shell generation, easily produce the shell cracking phenomena, thereby equipment can't normally move.
The utility model content
In order to eliminate the severe stress caused due to variations in temperature, prevent from leading the problem of shell cracking phenomena, the utility model provides adjustable shell stretching structure for a kind of simple in structure, convenient and practical isolated-phase enclosed bus.
The utility model is by the following technical solutions:
Adjustable shell stretching structure for a kind of isolated-phase enclosed bus, comprise connecting plate and expansion joint, and the expansion joint two ends connect respectively an end of connecting plate, connecting plate other end connection bus shell.
Further, the expansion joint hollow tubular structure, middle part has the arcuation projection, and both ends are provided with a plurality of grooves.
Further, expansion joint and bus shell connecting place are provided with stiffener.
Further, expansion joint is aluminium material.
The beneficial effects of the utility model:
By the setting of expansion joint, can be adjusted malalignment deviation between each section of bus, adjust test through installing on the spot, its maximum can reach ± 30mm of effect that adjusts; Rely on that shell is flexible, bending to bus carry out axially, horizontal, angular compensatory; Adopt this structure not only can play compensation absorb bus axially, laterally, the effect of angle thermal deformation; And can vibrate by absorption equipment, reduce the impact of vibration equipment on bus; Can also absorb earthquake, the earth subsidence deflection to bus; Overall structure is simple, easy to process, practical.
