Abstract
The utility model discloses a novel conductive device for an isolating switch. The conductive device comprises a plurality of rectangular conductive slices. The two ends of each rectangular conductive slice are equipped with compacting mechanisms. A connecting board provided with a screw hole is disposed at a side of each compacting mechanism. The number of aluminum sheets or copper sheets is selected according to current value. The two ends of each aluminum sheet are provided with two compacting mechanisms. A connecting board provided with a screw hole is disposed at a side of each compacting mechanism. The conductive device is fixed between the top conductive arm and the bottom conductive arm of the isolating switch through the connecting boards which replace primitive conductive discs. Because of good toughness and bending radiuses of the aluminum sheets or copper sheets constituting the novel conductive device, the telescopic movement of the isolating switch cannot be affected. Further, the novel conductive device is simple in structure, low in cost, good in conductive performance, unliable to damage, and easy to install and uninstall.
Description
Technical field
The utility model relates to a kind of high voltage isolator conductive equipment technical field, particularly a kind of isolating switch novel conductive device.
Background technology
Connecting portion between the upper and lower conductive arm of vertical-telescopic isolating switch has a conductive plate, and its effect is to provide guiding path for the current flowing of upper and lower conductive arm.This conductive plate appearance is used two semicircle plastic casings to being connected into a closed circle, by two bolts, these two semicircle plastic casings are fixed together, the parts such as conductive bead, alignment pin, compression spring, bracket are installed along the radial direction of conductive plate in conductive plate inside.Conductive bead outer surface is silver coating, has good electric action.In the time that isolating switch normally moves, play On current, in the time that isolating switch carries out breaking-closing operating, play the effect of rotation simultaneously.
Along with the increase of the operation time limit, two semicircle plastic casings of conductive plate appearance will be aging, break, the impurity such as rainwater and dust storm directly enters conductive plate inside, is attached on the outer surface of conductive bead, in the time that isolating switch carries out breaking-closing operating, along with the rotation of conductive bead, due to the existence of impurity, the silver coating of conductive bead outer surface is destroyed, and conducting surface is by severe oxidation, cause contact resistance to increase, contact-making surface heating; If impurity accumulates too much, also will cause the faults such as isolating switch breaking-closing operating is not in place, when isolating switch, because operation is not in place, in the time that half point narrows state, isolating switch will discharge to high voltage bus, the safety of serious threat electrical network and equipment.And traditional conductive plate complex structure, cost is high, installs and dismantle time-consuming taking a lot of work, and interruption duration is long, has a strong impact on the production of enterprise and the people's life.
Utility model content
The utility model is exactly for the problems referred to above, provide a kind of simple in structure, cost is low, conduct electricity very well, the isolating switch novel conductive device of not fragile, installation and convenient disassembly.
For achieving the above object, the utility model adopts following technical scheme, and a kind of isolating switch novel conductive device, comprises several rectangle conducting strips, and the two ends of rectangle conducting strip arrange hold-down mechanism, and a side setting of hold-down mechanism has the connecting plate of screw.
Described rectangle conducting strip length is 630mm, and width is 90mm, the aluminium flake that thickness is 0.2mm.
Described rectangle conducting strip length is 630mm, and width is 90mm, the copper sheet that thickness is 0.2mm.
Described rectangle conducting strip both sides are provided with groove, and elastic fastening mechanism is set in this groove.
Described elastic fastening mechanism is two press strips, and two press strip two ends connect by spring.
Described hold-down mechanism comprises an end opening rectangular housing, and clamp nut is set on housing, and the rectangle compressing tablet being connected with clamp nut is set in housing.
Electric installation of the present utility model is 630mm by length, width is 90mm, thickness is 0.2mm aluminium flake or copper sheet composition, select the quantity of aluminium flake or copper sheet according to size of current, the two ends of aluminium flake respectively with two hold-down mechanisms, one side setting of hold-down mechanism has the connecting plate of screw, by connecting plate, this electric installation is fixed between the upper and lower conductive arm of isolating switch, is used for substituting old-fashioned conductive plate.Because aluminium flake or the copper sheet of composition novel conductive device have good toughness and bending radius, thus can not have influence on the stretching motion of isolating switch, and the utility model is simple in structure, cost is low, conduct electricity very well, not fragile, installation and convenient disassembly.Described rectangle conducting strip both sides are provided with groove, the groove on both sides is corresponding, elastic fastening mechanism is set in this groove, described elastic fastening mechanism is two press strips, two press strip two ends connect by spring, and elastic fastening mechanism can prevent that aluminium flake or copper sheet from disperseing, after copper sheet or aluminium flake scatter, contact area is little, and conductivity declines; Another is convenient extends copper sheet or aluminium flake useful life.
