Background technology
At present, in single circuit power supply system, column support type chopper cannot meet both sides and all install disconnecting switch additional, the highest
Piezoelectricity arc stream carries out arc extinguishing through vacuum interrupter, can only accomplish that side installs integration disconnecting switch additional, and opposite side installs additional independent
The split type disconnecting switch of three-phase, if chopper breaks down, in the case of needing maintenance, after first forcing breaker open operation, work
Make personnel can only split type for three-phase disconnecting switch often be pulled open the most respectively, chopper just can be made to completely disengage from high-tension line, no
Only cause the increase of production cost, and need independent split-phase to operate, complex operation, take time and effort.
Summary of the invention
It is an object of the invention to provide a kind of double spacer leg formula choppers for single circuit power supply, it is characterized in that passing through
Manual pulling operation bar (1) can control contact knife on three-phase (5) and lower contact knife (10) and move up and down, when upper contact knife (5) and lower tactile
When cutter (10) contacts with upper contact knife seat (6) and outlet board (11) respectively, high-tension line inlet wire is connected, by height with inlet wire plate (2)
The outlet of line ball road is connected with outlet board (11), the most feasible one-tenth galvanic circle, when upper contact knife (5) and lower contact knife (10) touch with upper respectively
When tool rest (6) and outlet board (11) separate, can completely disengage from high-tension line, maintainer can safety inspection chopper.
For achieving the above object, the present invention provides following technical scheme:
A kind of double spacer leg formula choppers for single circuit power supply, insulating sleeve (7) is by SMC outsourcing silicone rubber once
Compacting forms, good insulation preformance, and insulating sleeve (7) inlet wire side and outgoing line side are separately installed with inlet wire plate (2), current transformer
(8), contact knife plate (4) is connected with inlet wire plate (2) and upper contact knife (5) respectively by pin (3), and vacuum interrupter (15) one end is fixed
In insulating sleeve (7) top, the other end is fixed in the middle of conductive clamp (16), and (18) one end that will be flexible coupling is fixed on conductive clamp (16)
Side, the other end is fixed on conducting rod (19), and upper contact knife seat (6) and lower contact knife seat (9) are separately fixed at vacuum interrupter
(15) and on conducting rod (19), lower contact knife (10) is connected with lower contact knife seat (9) by pin (3), is fixed on by outlet board (11)
On spacer leg (12), it is pasted with conjunction label (13) and minute mark board (14), manually pulling operation bar in action bars (1) both sides
(1) contact knife on three-phase (5) can be controlled and lower contact knife (10) moves up and down, high-tension line inlet wire is connected with inlet wire plate (2), will
High-tension line outlet is connected with outlet board (11), and manually pulling operation bar (1) is by upper contact knife (5) and lower contact knife (10) difference
Contact with upper contact knife seat (6) and outlet board (11), the most feasible one-tenth galvanic circle, be applied in single circuit power supply system, chopper
During as overhauled, after only needing breaker open operation, manually pulling operation bar (1) is by upper contact knife (5) and lower contact knife (10) difference
Separating with upper contact knife seat (6) and outlet board (11), chopper will completely disengage from high-tension line, and maintainer can overhaul safely
Chopper.
The beneficial outcomes of the present invention is: chopper both sides all add disconnecting switch, the most drop-down behaviour of staff
Make bar (1) and contact knife on three-phase (5) and lower contact knife (10) up and down motion can be controlled, thus control input and the excision of chopper,
Simple to operation, cost-effective.
Accompanying drawing explanation
Structural representation when accompanying drawing 1 is chopper of the present invention and disconnecting switch is in combined floodgate.
Structural representation when accompanying drawing 2 is chopper of the present invention and disconnecting switch is in separating brake.
Accompanying drawing 3 assembles internal view for insulating sleeve of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
In figure: 1, action bars 2, inlet wire plate 3, pin 4, contact knife plate 5, upper contact knife 6, upper contact knife seat 7, absolutely
Edge sleeve 8, current transformer 9, lower contact knife seat 10, lower contact knife 11, outlet board 12, spacer leg 13, conjunction mark
Board 14, minute mark board 15, vacuum interrupter 16, conductive clamp 17, be flexible coupling 18, conducting rod
As shown in Figure 1-2, the chopper both sides of the present invention all can install disconnecting switch additional, insulating sleeve (7) inlet wire side and going out
Line side is separately installed with inlet wire plate (2), current transformer (8), contact knife plate (4) by pin (3) respectively with inlet wire plate (2) and upper
Contact knife (5) is connected, and lower contact knife (10) is connected with lower contact knife seat (9) by pin (3), and outlet board (11) is fixed on spacer leg
(12), on, conjunction label (13) and minute mark board (14), staff's manually pulling operation bar it are pasted with in action bars (1) both sides
(1) contact knife on three-phase (5) can be controlled and lower contact knife (10) moves up and down, thus control input and the excision of chopper, operation
