Background technology
In many operating modes, need the A.C. contactor of the above big electric current of 2000A, there is following problems in the right A.C. contactor that uses at present: 1, according to traditional multipole parallel extended structural design, small product size is big, is unfavorable for the requirement of electrical control cubicles miniaturization; 2, required contact pressure is big, with closed realization, the poor reliability of being difficult for of electromagnetic attraction; 3, phase interpolar poor synchronization is unfavorable for the disjunction of contactor; 4, current-carrying link complexity, omnidistance pressure drop is big, and current-carrying efficient is low, is difficult to reach customer requirements.So need to develop a kind of customer requirements that satisfies, adapt to the A.C. contactor that modern power industry equipment uses.
Summary of the invention
The purpose of this utility model is to solve the problem that existing A.C. contactor exists, for special operation condition provides a kind of big electric current, jumbo A.C. contactor.
The technical scheme that the utility model technical solution problem adopts is as follows: A.C. contactor comprises pedestal, main contact, operating mechanism and arc control device, pedestal is made of top base and bottom base, the two is connected to an integral body, main contact has moving contact and fixed contact, be installed in respectively on the upper and lower pedestal, moving contact joins through flexible link and line bank, the moving contact multi-channel parallel, have run-on tab and bent plate on the fixed contact, different parts has the function of main contact and arcing contact on it; Described operating mechanism is a spring operating mechanism, adopts five connecting rod free tripping mechanisms, has energy-storage function, and mechanism comprises main shaft, linkage, energy-stored spring, extension spring, cam and separating brake semiaxis, and energy storage rotating shaft and main shaft flexibly connect; Each utmost point of main contact has independently arc control device, and striking sheet and multi-disc arc extinguishing grid pieces are housed in the outer cover of arc control device, and striking grid sheet is the pure iron product, and the parallel installation of multi-disc according to different requirements, can be installed the auxiliary contact group additional on the contactor.
Compare with the A.C. contactor of present application, the utlity model has following advantage: 1, spring operating mechanism is equipped with energy-stored spring, and mechanism always is in the energy storage position in the use, so the contactor flexible movements, closed and disconnected speed is very fast; 2, contact selects for use novel arc resistant material to manufacture, during work temperature rise slow, and contact system adopts multi-channel parallel, local current densities and electrodynamic repulsion force have been reduced, the thermal stability and the electronic stability of contact system have been improved, because moving contact is enclosed in separately the chamber, so class of insulation height; 3, arc quenching system has the arc extinguishing grid pieces that the multi-disc pure iron is manufactured, and arc extinguishing grid pieces is installed on the contactor pedestal, has both increased arc extinction performance, has improved mechanical strength again, unlikely breaking when big electric current disjunction, thus increased the useful life and the fail safe of product; 4, mounting means is versatile and flexible; 5, modular construction is convenient to dismounting and maintenance; 6, compact conformation, volume is little, and is applied widely.
