In order to solve above technical problem, the utility model provides a kind of high pressure to close common box bus, comprise upper cover plate, pressure release passage, housing, bus bars, fixed support, insulator and insulator supporting bracket, upper cover plate is located at above housing, housing upper surface is provided with pressure release passage, bus bars is fixed on fixed support, fixed support lower end connecting insulator, insulator is arranged in insulator supporting bracket, bus bars both sides arrange L-type respectively and fix collateral branch's support, fixing collateral branch's support upper end is by gim peg connection bus busbar, its both sides, lower end to be compressed with fixed support both ends by bolt and are connected, compress gasket is provided with between the support of fixing collateral branch and fixed support, fixing collateral branch's support rear connects semicircle rear backup plate, rear backup plate is provided with groove, groove blocks fixing bus bars, insulator supporting bracket is provided with pothole, and insulator lower end shape is corresponding with pothole, and extend in pothole, and insulator bottom face and pothole bottom junctions are provided with elastomeric pad, vertically insulating barrier is provided with in housing.
The utility model designs between three and is separated separately, form three independently spaces, thus external magnetic field is produced less, also phase fault can be avoided, common box bus body is closed for high pressure, install damping pad in systems in which additional, elasticity support is realized to insulator and bus bars, avoid mechanical shock and the seismic wave destruction of bringing to enclosed busbar that shell produces preferably.
The technical scheme that the utility model limits further is:
Aforementioned pressure release passage is circle, triangle or polygon; Housing cross-sectional is rectangle or ellipse, and housing and upper cover plate are aluminum alloy material or copper; Insulating barrier, the support of fixing collateral branch, rear backup plate, fixed support and edge supporting bracket are one or more of PVC plastic flitch, bakelite plate, epoxy glass laminate or plastic plate; Compress gasket and elastomeric pad are silicagel pad, nitrile rubber pad or fluorubber pad.
The utility model has excellent Short Circuit withstand performance, owing to having the protection of aluminium alloy or copper shell, effectively can weaken the structure heating that eddy current or circulation cause, reduce enclosed busbar skin temperature, reduce electric energy loss, improve ampacity, alleviate electric power.
The beneficial effects of the utility model are:
The utility model product adopts expansion joint, install simple, the adjustment of level, vertical direction two degrees of freedom can be realized, different temperature drop can not only be met and the flexible requirement caused of expanding with heat and contract with cold, error caused by foundation settlement can also be compensated, the degree of protection solving conventional skateboard formula retractor device is poor, installs trouble, runs insecure shortcoming.
In order to solve the vibrations of generation when transformer, generator and power distribution cabinet run to the negative effect of enclosed busbar, being connected outer employing at it with enclosed busbar and being flexible coupling; In order to avoid the accidental dew condensation phenomenon that winter, outdoor, indoor variations in temperature produced, wall bushing is set at place through walls, makes outdoor completely isolated with indoor enclosed busbar; During at right angle setting, flange is interior, and when level is installed, flange outside; In order to the permission improving enclosed busbar groove runs temperature rise, prevent the electrolytic corrosion in coastal outdoor and air butt joint that couple corrosion is serious, reduce contact resistance, enclosed busbar electric current is more than or equal to 3000A joint and all adopts silver-plated process, make its joint allow temperature rise to bring up to 65K, be much higher than temperature rise when normally working.
The utility model has that structure is simple, safe and reliable, pressure drop is little, moves towards flexible, easy for installation, the advantages such as Short Circuit withstand performance is good.
