Abstract
The utility model discloses a kind of interlock device of fixed breaker.It is fixed on framework 1 by guide pad 15, one end of screw mandrel 12 is through pilot hole, the other end through the pilot hole on framework 1 with 10 contact in flakes, 10 be arranged in rotating shaft 8 in flakes, rotating shaft 8 is through the pilot hole of fixed head 9, fixed head 9 is fixed on framework 1, and spring 11 is arranged on screw mandrel 12, and at framework 1 and in flakes between 10; When circuit breaker is transformed into interlocking position, rotating shaft 8 is rotated and is made 10 to be rotated down in flakes, and 10 Compress Springs 11 make screw mandrel 12 move downward in flakes, and then block switch knob 13, stops and closes a floodgate, and circuit breaker can be interlocked reliably when overhauling.This interlock method had both changed the bent plate connected mode of existing complexity, effectively improved guide vane end stop 2 simultaneously and blocked phenomenon not in place with guide vane end stop 3, adopt screw mandrel direct action, stop and close a floodgate, both easy to operate, safe and reliable again.
Description
Technical field
The utility model relate to a kind of fixed breaker interlocking device adopt screw mandrel move down stop switch knob press and directly realize interlock constructional device.
Background technology
Along with socioeconomic fast development, electricity needs constantly expands, power industry and power technology obtain significant progress, but the security of operation of power transmission and distribution product and quality need to be improved further, particularly reliable, safety should be gived top priority, so our power product should to energy-saving safe, structure future development simple, quick for installation, easy to maintenance.
The interlock method of existing indoor fixed breaker is as shown in Figure 1, 2: comprise guide vane end stop 2, guide vane end stop 3, bolt 4, bolt 5, bent plate 6, bent plate 7 in interlocking device.Guide vane end stop 3 and bent plate 6, bent plate 6 and bent plate 7 are linked together by bolt 5, and whole interlock assembly is linked together by bolt 4 and framework 1; Guide vane end stop 2, switch knob 13 are fixed in combined floodgate rotating shaft 14.When circuit breaker is transformed into interlocking position, bent plate 7 rotates and drives bent plate 6 to move down through bolt 4, and then bent plate 6 drives guide vane end stop 3 to rotate up through bolt 4, blocks guide vane end stop 2, and combined floodgate rotating shaft cannot be rotated, and realizes interlocking.This interlock assembly drawback is: 1, in interlocking process, part is too much, and interlocking is complicated, and guide vane end stop 2 and guide vane end stop 3 easily engage not in place, affect serviceability; 2, because the material of guide vane end stop 2, guide vane end stop 3 is nylon, in interlock circuit, useful life is shorter.
Utility model content
The purpose of this utility model is a kind of interlocking device's device that can be used for fixed breaker of design.
The technical solution of the utility model: guide pad 15 is fixed on framework 1, one end of screw mandrel 12 is through the pilot hole on guide pad 15, the other end through the pilot hole on framework 1 with 10 contact in flakes, 10 be arranged in rotating shaft 8 in flakes, rotating shaft 8 is through the pilot hole of fixed head 9, fixed head 9 is fixed on framework 1, and spring 11 is arranged on screw mandrel 12, and at framework 1 and in flakes between 10; When circuit breaker operating handle is transformed into interlocking position, rotating shaft 8 is rotated and is made 10 to be rotated down in flakes, and 10 Compress Springs 11 make screw mandrel 12 move downward in flakes, and then block switch knob 13.
By changing mounting means and the position of existing interlock, allowing screw mandrel directly act on switch knob, making interlock circuit directly, safely, reliably.
Accompanying drawing explanation
Fig. 1 is the left view of existing circuit breaker interlock mounting means;
Fig. 2 is the end view of existing circuit breaker interlock mounting means;
Fig. 3 is the front view of the utility model interlock mounting means;
Fig. 4 is the partial enlarged drawing of A in the utility model interlock mounting means front view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, framework 2, guide vane end stop 3, guide vane end stop 4, bolt 5, bolt 6, bent plate 7, bent plate 8, rotating shaft 9, fixed head 10, in flakes 11, spring 12, screw mandrel 13, switch knob 14, combined floodgate rotating shaft 15, guide pad
As shown in Figure 3; the mode that the utility model circuit breaker interlock assembly realizes interlocking is: when circuit breaker is transformed into interlocking position; rotating shaft 8 rotates; drive 10 being rotated down in flakes in rotating shaft 8,10 Compress Springs 11 make screw mandrel 12 move downward in flakes, and then block switch knob 13; stop and close a floodgate; circuit breaker can be interlocked reliably when overhauling, preventing misoperation, the safety of proterctive equipment and personnel.
The circuit breaker interlock assembly device that the utility model provides, changes the bent plate connected mode of existing complexity, effectively improves guide vane end stop 2 simultaneously and blocks phenomenon not in place with guide vane end stop 3, adopt screw mandrel direct action, stop and close a floodgate, both easy to operate, safe and reliable again.
