Abstract
A mechanical interlocking device used for universal circuit breakers comprises a fixed plate, a roller, a support, a spring, a lock nut, a release member, a feedback plate, a wire rope, etc. According to the utility model, the moment change generated in the movement of the spring guarantees the high reliability of the motion of a product, a plurality of logic cooperation relations of two or three universal circuit breakers are realized, and the mechanical interlocking device used for universal circuit breakers is characterized in that the structure is simple, the reliability is high, debugging is convenient, and application is wide.
Description
Technical field:
The utility model belongs to the low voltage electrical apparatus technology field, particularly a kind of mechanical interlocks of omnipotent breaker.
Background technology:
The mechanical interlocks of existing omnipotent breaker has complex structure, and reliability is low, debug loaded down with trivial detailsly, and needs use different components and parts combinations when satisfying different on/off switch and cooperating, and bring inconvenience to management, for this reason, be badly in need of a kind of new interlock and solve above technical barrier.
The utility model content:
The object of the present invention is achieved like this: a kind of mechanical interlocks for omnipotent breaker is characterized in that: comprise fixed head, roller bearing, support, spring, locking nut, dropout part, feedback board and steel wire rope etc.; This device can satisfy simultaneously the user different require instructions for use.
In interlock, support 2 is connected by a spring 5 with support 10, the angle of the power of this spring and support 2 obviously greater than with the power angle of support 10, and this spring to the moment of support 2 obviously greater than the moment to support 10, benefit has two: one, and concerning support 10, when device itself did not move, spring was little to the moment of support 10, corresponding little to the reaction force of omnipotent breaker main shaft, be beneficial to breaker mechanism and close a floodgate; When support 10 rotated, the pulling force of spring and its angle constantly reduced, and the resistance arm of support is constantly reduced, and the resistance that main shaft is produced is more conducive to mechanism's combined floodgate apart from constantly reducing; The 2nd, concerning support 2, when device itself did not move, spring was large to the moment of support 2, was conducive to the stable of this device; When support 10 rotated, the angle of the pulling force of spring and its support 2 constantly increased, and the arm of force of support 2 is constantly increased, and the stabilizing moment of support 2 generations is constantly increased, and was conducive to the stability of support 2.
This device can satisfy all combinational logics that close minute of two omnipotent breakers, totally two kinds, connects and sees Fig. 2
This device can satisfy all combinational logics that close minute of three omnipotent breakers, totally six kinds, connects and sees Fig. 3
A kind of mechanical interlocks for omnipotent breaker of the present invention has simple in structurely, and reliability is high, and debugging is convenient, widely used characteristics.
Description of drawings:
Fig. 1 is front and the side structure schematic diagram of the mechanical interlocks of a kind of circuit breaker of the present invention.
Fig. 2 is the syndeton schematic diagram that the mechanical interlocks of a kind of circuit breaker of the present invention satisfies two omnipotent breakers.
Fig. 3 is the syndeton schematic diagram that the mechanical interlocks of a kind of circuit breaker of the present invention satisfies three omnipotent breakers.
Wherein:
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1, this mechanical interlocks comprises: the 1-roller bearing, and the 2-support, the 3-fixed head, the 4-wirerope, the 5-spring, the 6-locking nut, 7-wirerope sheath, 8-dropout part, 9-feeds back part
When being applied to two omnipotent breaker A and B, a steel cable 4 of interlock A feedback board 9, annular is enclosed within on the roller bearing 1 of the roller bearing 1 of interlock A and interlock B feedback board 9, locks after being adjusted to suitable position by locking nut 6.Accordingly, a steel cable 4 of the feedback board 9 of interlock B, annular is enclosed within on the roller bearing 1 of the roller bearing 1 of interlock A and interlock B feedback board 9, locks after being adjusted to suitable position by locking nut 6.When omnipotent breaker A closed a floodgate, the feedback board 9 of interlock A rotated, and the dropout part 8 that drives interlock B rotates, and pushes down the dropout semiaxis of omnipotent breaker B, guaranteed that omnipotent breaker B can not close a floodgate.Vice versa.
When being applied to three omnipotent breaker A, B, C, a steel cable 4 of interlock A dropout part 8, annular is enclosed within on the interlock A dropout part 8, and both sides link to each other with the feedback board 9 of the feedback board 9 of interlock B and interlock C respectively and are locked nut 6 lockings; Accordingly, a steel cable 4 of interlock B dropout part 8, annular is enclosed within on the interlock B dropout part 8, and both sides link to each other with the feedback board 9 of the feedback board 9 of interlock A and interlock C respectively and are locked nut 6 lockings; Accordingly, a steel cable 4 of interlock C dropout part 8, annular is enclosed within on the interlock C dropout part 8, and both sides link to each other with the feedback board 9 of the feedback board 9 of interlock A and interlock B respectively and are locked nut 6 lockings;
When only allowing a breaker closing, mix up in advance wirerope length, after the locking, when omnipotent breaker A closes a floodgate, a steel cable 4 of interlock A feedback board 9, the roller bearing 1 of interlock B dropout part 8 and interlock C dropout part 8 is rotated, push down respectively the dropout semiaxis of omnipotent breaker B and C, guarantee that omnipotent breaker B and circuit breaker C can not close a floodgate.Other situations are as the same.
When only allowing two breaker closings, mix up in advance wirerope length, after the locking, when omnipotent breaker A closes a floodgate, a steel cable 4 of the feedback board 9 of interlock A, the roller bearing 1 of interlock B dropout part 8 and interlock C dropout part 8 is rotated, run into respectively the dropout semiaxis of omnipotent breaker, this moment, omnipotent breaker B and omnipotent breaker C can close a floodgate, when omnipotent breaker B closes a floodgate, a steel cable 4 of the feedback board 9 of interlock B, the roller bearing 1 of interlock A dropout part 8 and interlock C dropout part 8 is rotated, and this moment, the dropout semiaxis of omnipotent breaker C was held down, and can not close a floodgate, the dropout semiaxis of omnipotent breaker A is just run into, and can not trip.Other situations are as the same.
