Abstract
The present invention relates to a kind of withdrawable circuit breaker preventing body inclination movement.Be characterized in that it includes drawout chassis and breaker body, it also includes an eccentric shaft being connected in described side plate top, drawout chassis both sides and can be used for pushing down described breaker body upper surface, described eccentric shaft has one for being pressed in the cylinder of described breaker body upper surface, be fixed with the platform of an outer-hexagonal shape in described cylindrical one end, the eccentric part of the platform other end of described outer-hexagonal shape is fixed with one and can be used for the threaded cylinder be fastened on described drawout chassis both sides side plate and the nut mated with it.The present invention acts on breaker body by increasing eccentric shaft, because axle is eccentric, by regulating, torsional interaction power all being acted on body by axle, can prevent breaker body from moving or tilting when there is especially big (or limit) short circuit current.
Description
Technical field
The invention belongs to a kind of withdrawable circuit breaker, particularly relating to a kind of circuit breaker in drawout chassis can prevent body inclination movement withdrawable circuit breaker when running into especially big (or limit) short circuit current.
Background technology
The breaker body of usual withdrawable circuit breaker is contained in drawout chassis side plate, and by worm drive, the roller on side plate is pinned by the hook on drawout chassis main shaft, namely body position is also pinned, and has adjustable rollers to play supporting body effect at body bottom portion simultaneously.But body leans forward owing to running into powerful electric power or is moved when running into especially big (or limit) short circuit current, although roller blocks by the hook at drawout chassis main shaft two ends, but body also has the movement of 2-5mm, the movement of body can cause tactile bridge and busbar to burn causing test not pass through smoothly.This is the technical barrier that circuit breaker exists.
Summary of the invention
The present invention provides a kind of withdrawable circuit breaker preventing body inclination movement for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: it includes drawout chassis and breaker body, it also includes an eccentric shaft being connected in described side plate top, drawout chassis both sides and can be used for pushing down described breaker body upper surface, described eccentric shaft has one for being pressed in the cylinder of described breaker body upper surface, the platform of an outer-hexagonal shape is fixed with in described cylindrical one end, the eccentric part of the platform other end of described outer-hexagonal shape is fixed with one and can be used for the threaded cylinder be fastened on described drawout chassis both sides side plate and the nut mated with it.
The advantage that the present invention has and good effect are: act on Switch main body by increasing eccentric shaft, because axle is eccentric, by regulating, torsional interaction power is all acted on body by axle, also ensure that body passes in and out drawout chassis smoothly, can prevent breaker body from moving or tilting when there is especially big (or limit) short circuit current simultaneously.
Accompanying drawing explanation
Fig. 1 is the perspective view of eccentric shaft of the present invention;
Fig. 2 is the main TV structure schematic diagram of eccentric shaft of the present invention;
Fig. 3 is general structure schematic diagram of the present invention.
Embodiment
For content of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, 2, 3, eccentric shaft (2) has one for being pressed in the cylinder (4) of breaker body (3) upper surface, have the platform (5) of an outer-hexagonal shape in one end of cylinder (4), the eccentric part of platform (5) other end of outer-hexagonal shape has one to can be used for being fastened on the threaded cylinder (6) on the side plate of drawout chassis (1) both sides.Breaker body (3) loads in drawout chassis (1), eccentric shaft (2) is installed on the side plate of drawout chassis (1) (for the ease of seeing the position relationship between eccentric shaft (2) and breaker body (3) and drawout chassis (1) clearly, the side plate of the opposite side of drawout chassis (1) is eliminated) in Fig. 3, platform (5) part being acted on the middle outer-hexagonal shape of axle (2) by common wrench carrys out regulating shaft (2), until axle (2) is pressed on body (3), threaded cylinder (6) one end of axle (2) adds washer nut and fastening with on the side plate of drawout chassis (1).
Claims (1)
1. one kind prevents the withdrawable circuit breaker of body inclination movement, it includes drawout chassis and breaker body, it is characterized in that: further comprising the eccentric shaft having to be connected in described side plate top, drawout chassis both sides and to can be used for pushing down described breaker body upper surface, described eccentric shaft has one for being pressed in the cylinder of described breaker body upper surface, the platform of an outer-hexagonal shape is fixed with in described cylindrical one end, the eccentric part of the platform other end of described outer-hexagonal shape is fixed with one and can be used for the threaded cylinder be fastened on described drawout chassis both sides side plate and the nut mated with it.
