Embodiment
Contrast accompanying drawing below; Through description to embodiment; Effect and operation principle, the manufacturing process of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept of the present invention, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art.
The of the present invention structure expressed like Fig. 2, Fig. 3 and Fig. 4 is a kind of backlocking mechanism of switchgear, and described switchgear comprises switchgear body 1, cable vault 2, panel 3, earthed switch 4, earthed switch operating axis 5, main switch 6.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective; The panel that is implemented in switch cubicle is not under the closing state; Guarantee the goal of the invention that switchgear can't be switched on and moved, the technical scheme that the present invention takes is:
The backlocking mechanism of switchgear provided by the present invention is located at the position that earthed switch operating axis 5 is positioned at an end of said panel 3; Adopt clutch configuration; Promptly on described switchgear body 1, establish release pin 10, establish clutch cover 9, establish transverse groove on the described clutch cover 9 in the end of described earthed switch operating axis 5; When described panel 3 was opened, described release pin 10 snapped in described transverse groove; When described panel 3 was closed, described release pin 10 broke away from described transverse groove.
The backlocking mechanism 11 increase positions of clutch type are as shown in Figure 2.
Characteristics of the present invention are the backlocking mechanisms 11 that adopted clutch type.Realize panel 3 under the situation of not closing, then the switchgear function of operation of can't switching on.Its objective is the reliability that improves 10kV armored metal withdraw-type switchgear " five is anti-" interlocking, further perfect " five is anti-" interlocking device technology solves because the potential safety hazard that operating personnel's misoperation brings is guaranteed switchgear and personnel's life security.The method that clutch type backlocking mechanism adopts elastic press type to thread off is connected clutch type backlocking mechanism 11 and is used with earthed switch operating axis 5; When panel 3 is closed (isolated high-voltage electricity, eliminate safe hidden trouble), through guide rod 8 release pin 10 is removed in the clutch cover groove, can operational grounding switch 4, make switchgear be in the preparation work state; Thereby realize the effect of back lower panel backlocking mechanism.The outstanding feature of this invention is: 1, operation principle and simple in structure, 2, this mechanism's parts manufacture craft is simple, 3, the backlocking reliability is high, 4, non-maintaining, stable work in work.
The operation principle of said mechanism is:
As shown in Figure 3; When panel 3 was in opening, the backlocking mechanism 11 of clutch type worked, and release pin 10 gets in the groove of clutch cover 9; Operating personnel can't operational grounding switching manipulation axle 5; Under the interlocking effect of earthed switch 4 and main switch 6, main switch 6 can't be operated the service position, and causes switch equipment can't move;
As shown in Figure 4, when panel 3 is in closed condition, backlocking mechanism 11 lockings of clutch type are untied; Release pin 10 leaves the groove of clutch cover 9; Operating personnel can operational grounding switching manipulation axle 5, and earthed switch 4 is in gate-dividing state, and earthed switch 4 is untied with the interlocking of main switch 6; Main switch 6 is operable to the service position, the switchgear operation of can switching on.
Release pin 10 of the present invention snaps in and breaks away from described transverse groove is to be realized by following structure:
The clutch type backlocking mechanism course of work is:
1, as shown in Figure 3; When panel 3 was in opening, clutch cover 9 moved to the opening direction of panel 3 under the effect of back-moving spring 7 compression stresses through guide rod 8, caused release pin 10 to get in the groove of clutch cover 9; Like this can't operational grounding switch 4; Be that operational grounding switching manipulation axle 5 can't rotate, make the switchgear operation of under the effect of various interlockings, can not switching on, guarantee to install or maintenance safety.
2, as shown in Figure 4; After installation or maintenance finished, after operating personnel must close panel 3, panel 3 compression guide rods 8 made clutch cover 9 move to the closing direction of panel 3; Cause release pin 10 to leave in the groove of clutch cover 9; Operating personnel can operational grounding switch 4 like this, makes switchgear be in the running status of can switching on, and prepares operation at any time.
Concrete structure of the present invention is
Owing to adopted two guide rods 8, make 8 pairs of clutch cover 9 equilibriums of guide rod.
Said structure makes the simple in structure of backlocking mechanism 11, and is easily manufactured.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
