Abstract
The utility model discloses a special electrified small bus cutter with a triangular knife. The special cutter comprises an insulating support and the triangular knife, wherein a base is arranged at the lower end of the insulating support; a cantilever slab is arranged at the upper end of the insulating support; a through hole is formed on the cantilever slab; a threaded copper rod is sleeved in the through hole; the threaded copper rod is in clearance fit with the through whole; an insulating screw cap is arranged at the upper end of the threaded copper rod; the lower end of the threaded copper rod is in movable connection with the knife handle of the triangular knife; an arc-shaped groove is formed on the lower end surface of the cantilever slab; the arc-shaped groove is matched with the triangular knife in position; and a movable baffle plate is arranged on the outer side surface of the cantilever slab. The special cutter has a good insulating property, effectively reduces the risks in cutting a secondary small bus in the process of replacing a protection screen, reduces electric accidents, and meanwhile improves the work efficiency.
Description
One. technical field: the utility model relates to a kind of power system secondary specialty screen in service and pushes up the cutting device of little bus under charged situation, particularly relates to a kind of charged little bus triangle cutter dedicated truncate device.
Two. background technology: the 10KV that present domestic protective relaying device producer forms a complete production network and the protection screen of above electric pressure, the required AC and DC power supply of its device and secondary AC voltage sample value all must be installed the little bus that the screen screen pushes up and extract from each.Little bus processes because of rules require the solid pure copper material of many employings; And the medium and small bus of newly-built substation secondary installing engineering all is to adopt whole to be communicated with the mode of laying; Install though promptly row's protection screen is independent separately; But the little bus on the screen top but is an integral body, and this just can withdraw from after need blocking charged little bus in service when just having caused protection screen to change separately.
Because working space is narrow and small, have only 30mm with spacing between the little bus of layer, two-layer up and down little bus spacing also has only 60mm, and to move little bus all be to kill on little bus structure with screw, can't use the such instrument of cast cutter to block operation.When the relay protection personnel worked at the little bus that blocks solid fine copper diameter 6mm and 8mm, the most general instrument of usefulness was exactly a cable grip.Use cable grip danger very,, open jaw and be easy to cause between adjacent two little buses short circuit or when blocking, cause accidents such as little busbar grounding because mistake is bumped protection screen screen top because the jaw position of cable grip all is a metal material.The relay protection personnel adopt insulating tape to be insulated with the way which floor insulating tape wraps more in the jaw position more; But insulating tape comes off because cable grip in truncated process, is exerted oneself excessive or runs into sharp object and break through regular meeting, and this just needs personnel to block a little bus will check that once finding has the place of insulation damages to wrap one deck again; Adjacent little bus also will separate just with megohmite insulant can carry out operation; Trouble very, and use cable grip heaviness very, inconvenience.
Three. the utility model content:
The utility model technical problem to be solved is: overcome the deficiency of prior art, a kind of reasonable in design, easy to use, high efficiency and the good charged little bus triangle cutter dedicated truncate device of security are provided.
The technical scheme of the utility model is: a kind of charged little bus triangle cutter dedicated truncate device, contain insulating support and triangle cutter, and said insulating support lower end is provided with base; Its upper end is provided with cantilever slab; Said cantilever slab is provided with through hole, is set with the screw thread copper rod in this through hole, and the two is a matched in clearance; Said screw thread copper rod upper end is provided with the insulation nut; Its lower end is connected with the hilt of said triangle cutter is movable, and said cantilever slab lower surface is provided with deep-slotted chip breaker, and the position of this deep-slotted chip breaker and said triangle cutter are complementary.The lateral surface of said cantilever slab is provided with movable baffle plate.Said movable baffle plate is processed by insulating materials.
The beneficial effect of the utility model is:
1, the utility model good insulation preformance, the little bus of secondary that has reduced in the protection screen replacing process blocks the dangerous spot that exists in the work, has reduced electric power accident, has improved operating efficiency simultaneously.
2, the blade of the utility model triangle cutter upper end is very thin, help cutting off little bus, and the blade lower end is thicker, has enough intensity, is not easy fracture to guarantee the triangle cutter, increases the service life of triangle cutter.
3, the utility model applied range, internal diameter are that the little bus of 1mm to 8mm is all applicable, can conveniently accomplish blocking with jumper connection two of the little bus livewire work of relay protection specialty secondary and work mutually, and it is good to promote the back comprehensive benefit.
Four. description of drawings:
Fig. 1 is the structural representation of charged little bus triangle cutter dedicated truncate device;
The state diagram that Fig. 2 cuts little bus for charged little bus triangle cutter dedicated truncate device shown in Figure 1;
Fig. 3 is the structural representation of insulation nut shown in Figure 1;
Fig. 4 is the vertical view of triangle cutter shown in Figure 1;
Fig. 5 is the structural representation of insulation nut and the mutual clamping of ratchet spanner.
Five. the specific embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-insulating support, 2-triangle cutter, 3-screw thread copper rod, the little bus of 4-, the 5-nut that insulate, the movable baffle plate of 6-, 7-ratchet spanner.
Charged little bus triangle cutter dedicated truncate device contains insulating support 1 and triangle cutter 2, and wherein, insulating support 1 lower end is provided with base; Its upper end is provided with cantilever slab, and cantilever slab is provided with through hole, is set with screw thread copper rod 3 in this through hole; The two is a matched in clearance, and screw thread copper rod 3 upper ends are provided with insulation nut 5, and its lower end is connected with the hilt of triangle cutter 2 is movable; The cantilever slab lower surface is provided with deep-slotted chip breaker, and the position of this deep-slotted chip breaker and triangle cutter 2 are complementary.
As required, can be provided with movable baffle plate 6 on the lateral surface of cantilever slab, and movable baffle plate 6 is processed by insulating materials.
During use; At first the screw thread copper rod 3 with M6 inserts in the through hole of cantilever slab, and the hilt rotation that will have the triangle cutter 2 of endoporus M6 then is screwed into screw thread copper rod 3 lower ends of M6, is screwed into the insulation nut 5 of internal diameter M6 in screw thread copper rod 3 upper ends; The little bus 4 that needs are blocked is enclosed between the deep-slotted chip breaker of triangle cutter 2 and cantilever slab lower surface; Movable baffle plate 6 is left behind, form enclosure space, utilize ratchet spanner 7 to turn clockwise at last; Promote triangle cutter 2 through insulation nut 5, thereby little bus 4 is blocked work.
