Description
Technical field
The present invention relates to a kind of frock, particularly a kind of horizontal centering frock that is used for the installation of 126kV arc-extinguishing chamber of circuit breaker.
Background technology
Primary cut-out is an electrical equipment of controlling and protect usefulness in the electric power system.The world and domestic manufacturer generally adopt artificial butt joint during its body assembling; The mode of free centering guarantees that the dynamic and static contact of breaker body is in the centering state; This kind docking mode is very high for labor claim; Because the manual operation poor stability is so the undesirable situation of centering often occurs.
When centering is defective,, then not obvious to the influence of major loop resistance if deviation is less; And can realize through adjustment divide-shut brake spring for the influence of circuit breaker characteristic; If but the adjustment of divide-shut brake spring is bigger, then long-play tired situation very easily occurs with rear spring, thereby causes product to be difficult to smooth divide-shut brake; Cause product failure, thereby appearance can not be opened the risk of make and break product blast not in place.If deviation is bigger, then obviously to major loop resistance influence, if contact site heating when failing to find then after the product operation, to run into short circuit current when dispatching from the factory; Burn after overheated; The blast equivalent risk appears in product, when the accuracy of alignment deviation is big in addition, to the mechanical property influence obviously; Being difficult to through adjustment divide-shut brake spring under the certain situation is that the product mechanical property reaches specification requirement; This just need take underproof product body apart, and centering and change the associated damage parts makes accuracy of alignment reach requirement again.
Summary of the invention
The technical problem that the present invention will solve provides the centering frock that a kind of 126kV of being used for arc-extinguishing chamber of circuit breaker is installed, and can improve centering efficient, guarantee accuracy of alignment.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of 126kV arc-extinguishing chamber of circuit breaker centering frock, comprise frame, and be located at the centering platform on the frame; Its innovative point is: also comprise a stationary fixture platform; Be fixed on an end of centering platform, its medial surface is provided with the notch cuttype round platform, and the fixedly clamp system of arc-extinguishing chamber of circuit breaker supporting seat is installed on the stationary fixture platform of round platform both sides; One floating holder platform; This floating holder platform is installed in the corresponding setting with the stationary fixture platform of the other end of centering platform; Its bottom is slidingly matched with the line slideway that is horizontally set on the centering platform; The medial surface of floating holder platform is provided with the notch cuttype round platform, and the round platform center of said floating holder platform is provided with stationary contact headstock clamp system; The round platform central axis of said stationary fixture platform and the round platform central axes of floating holder platform.
Further, the said clamp system that is used for fixing the arc-extinguishing chamber of circuit breaker supporting seat is quick elbow folder.
Further, said stationary contact headstock clamp system comprises support, jaw, pull bar, connecting rod and clamping cylinder, and the jaw middle part is connected with the cantilever tip bearing pin, and jaw is terminal to be connected with pull bar through connecting rod, and pull bar is connected fixing with the clamping cylinder.
Further; The side of said centering platform is provided with position-limit mechanism, comprises that several are fixed on the support on the centering platform, is installed with horizontally disposed screw rod in the perforate on support top; The top of said screw rod connects postive stop baffle, and screw rod is fixed on the support through nut check.
The invention has the advantages that: when carrying out centering; Utilize mechanically aided hand that the arc-extinguishing chamber of circuit breaker supporting seat is horizontally disposed with; Its bottom is enclosed within on the notch cuttype round platform of stationary fixture platform; And arc-extinguishing chamber of circuit breaker supporting seat bottom end face is close to the shoulder of round platform through clamp system, make arc-extinguishing chamber of circuit breaker supporting seat central axis and round platform central axes, i.e. moving contact and round platform central axes in the arc-extinguishing chamber of circuit breaker supporting seat; Stationary contact headstock bottom with arc-extinguishing chamber of circuit breaker is enclosed within on the round platform of floating holder platform; The shoulder of stationary contact headstock bottom end face being close to round platform through the clamp system at its center; Make arc-extinguishing chamber of circuit breaker stationary contact headstock central axis and round platform central axes, i.e. fixed contact and round platform central axes in the arc-extinguishing chamber of circuit breaker stationary contact headstock.Then, promote the floating holder platform and move to the stationary fixture platform, accomplish dynamic and static contact butt joint, can guarantee the axiality high-precision requirement of dynamic and static contact along line slideway.
The clamp system that is used for fixing the arc-extinguishing chamber of circuit breaker supporting seat is quick elbow folder, and simple in structure, buying is convenient.And when clamping the stationary contact headstock, because its length is long, weight is big, and traditional clamping measure is after clamping the stationary contact headstock, and stationary contact headstock end is sagging, causes stationary contact headstock central axis skew round platform axis.Stationary contact headstock clamp system utilizes jaw to clamp the gap of stationary contact headstock bottom cylinder side wall when clamping, and makes the stationary contact headstock be close to round platform, has guaranteed the coincidence of both central axis.
The centering platform side is provided with position-limit mechanism, can when operating personnel lift arc-extinguishing chamber of circuit breaker, more fast arc control device supporting seat and stationary contact headstock be installed on the round platform.
