Description
Technical field
The present invention relates to a kind of frock, particularly a kind of horizontal centering tooling of installing for 126kV arc-extinguishing chamber of circuit breaker.
Background technology
Primary cut-out is the electrical equipment that in electric power system, control and protection is used.During its body assembling, the world and domestic manufacturer generally adopt artificial docking, the mode of freedom centering guarantees that the dynamic and static contact of breaker body is in Shaft alignment state, this kind of docking mode is very high for labor claim, due to manual operation poor stability, so often there is the undesirable situation of centering.
When centering is defective, if deviation is less, not obvious to major loop Resistance Influence, and can realize by adjusting divide-shut brake spring for the impact of circuit breaker characteristic, if but the adjustment of divide-shut brake spring is larger, long-play very easily occurs tired situation with rear spring, thereby cause 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 larger, obvious to major loop Resistance Influence, contact site heating while finding if fail while dispatching from the factory to run into short circuit current after product operation, after overheated, burn, there is blast equivalent risk in product, when accuracy of alignment deviation is larger in addition, on mechanical property impact obviously, under certain situation, being difficult to by adjusting divide-shut brake spring is that product mechanical property reaches specification requirement, this just need to take underproof product ontology apart, again centering change associated damage parts, makes accuracy of alignment reach requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of centering tooling of installing for 126kV arc-extinguishing chamber of circuit breaker, can improve centering efficiency, 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 extinguish chamber centring frock, comprise frame, be located at the centering platform in frame, its innovative point is: also comprise a stationary fixture platform, be fixed on one end of centering platform, its medial surface is provided with 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 arranged on the other end setting corresponding to stationary fixture platform of centering platform, its bottom is slidably matched with the line slideway being horizontally set on centering platform, the medial surface of floating holder platform is provided with notch cuttype round platform, and the round platform center of described floating holder platform is provided with fixed contact pedestal clamp system; The round platform central axis of described stationary fixture platform and the round platform central axes of floating holder platform.
Further, described is quick elbow folder for the fixing clamp system of arc-extinguishing chamber of circuit breaker supporting seat.
Further, described fixed contact pedestal clamp system comprises support, jaw, pull bar, connecting rod and clamping cylinder, and jaw middle part is connected with cantilever tip bearing pin, and jaw end is connected with pull bar by connecting rod, and pull bar and clamping cylinder are connected and fixed.
Further, the side of described centering platform is provided with position-limit mechanism, comprises several supports that are fixed on centering platform, is installed with horizontally disposed screw rod in the perforate on support top, the top of described screw rod connects postive stop baffle, and screw rod is fixed on support by nut check.
The invention has the advantages that: while carrying out centering, utilize mechanically aided hand that 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 by clamp system, arc-extinguishing chamber of circuit breaker supporting seat bottom end face is close to the shoulder of round platform, 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 arc-extinguishing chamber of circuit breaker supporting seat; The fixed contact pedestal bottom of arc-extinguishing chamber of circuit breaker is being enclosed within on the round platform of floating holder platform, the shoulder of round platform is close to fixed contact pedestal bottom end face by clamp system by its center, make arc-extinguishing chamber of circuit breaker fixed contact pedestal central axis and round platform central axes, i.e. fixed contact and round platform central axes in arc-extinguishing chamber of circuit breaker fixed contact pedestal.Then, promote floating holder platform and move to stationary fixture platform along line slideway, complete dynamic and static contact docking, can guarantee the axiality high-precision requirement of dynamic and static contact.
Being used for the fixedly clamp system of arc-extinguishing chamber of circuit breaker supporting seat is quick elbow folder, and simple in structure, buying is convenient.And when clamping fixed contact pedestal, because its length is long, weight is large, traditional clamping measure is after clamping fixed contact pedestal, and fixed contact pedestal end is sagging, causes fixed contact pedestal central axis skew round platform axis.Fixed contact pedestal clamp system, when clamping, utilizes jaw to clamp the gap of fixed contact pedestal bottom cylinder side wall, makes fixed contact pedestal be close to round platform, has guaranteed the coincidence of both central axis.
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 fixed contact pedestal be arranged on round platform.
