A kind of modular vacuum magnetic starter of the invention compared with prior art has following beneficial effect:
1, a kind of modular vacuum magnetic starter of the invention, by the architecture advances to calutron and vacuum tube, arrangesBecome by the directly drive combined floodgate of three vacuum tubes and the version of gate separating type of three calutrons difference, make contact modulesRear volume reduces, and circuit reduces, by contactor is combined after the modularization of controller to the starting of composition modular magnetic force with controllerAfter device, there is volume little, maintenance and easy to maintenance, the replacing module time can not exceed three minutes, and (contactor in the past goes wrongWanting discriminatory analysis is the problem of contactor or the problem of controller, is perhaps other relaying, power supply etc. problem. Used time is with regard to phaseWhen long), in conjunction with the control system carrying, the situation of contactor and controller split is in the past improved, realize electromechanicalChange function. Contact modules, conforms to concerned countries standard completely, because controller and contactor are combined in one, at volume and heavyAmount aspect is able to very large improvement. For example same 630A contactor assembly is the half of original contactless contactor volume and weightAlso wanted point. Because three-phase is used respectively three magnet control, alternate 120 degree that differ, can make disjunction at zero point (sine waveZero point), protection vacuum tube contact arcing damage and adhesion phenomenon.
After magnetic starter modularization, according to the withstand voltage 25KV that reaches of the standard of GB/T14808, contactor and electricity are in the past solvedSub-controller does not reach a difficult problem of withstand voltage 25KV on coordinating. Electric current is electric power system in 630A, and voltage is from 380V to 3300VCan adopt the modular vacuum magnetic starter of the invention.
After magnetic starter modularization, the input of vacuum tube and output are arranged in a side and are staggered, and can rise with magnetic forceThe framework of moving device module outside is module rack composition push-pull mechanism (drawer type), make magnetic starter convenient separate with main circuit andClose grandly, realize quick-replaceable object.
2, three-phase vacuum tube and calutron, every group is all to form respectively. With three large electricity of high-speed double electromagnet vacuum tube of Electronic ControlStream disjunction at zero point. Solved vacuum tube in the time of main circuit phase fault, large electric current disjunction generation electric arc makes the dynamic/static contact of vacuum tubeThe phenomenon of melting welding. Modular vacuum magnetic starter of the present invention adopts direct current adhesive and maintenance, makes the operating voltage of electromagnetScope increases greatly, and the direct current adhesive of 300V left and right is low to moderate 15V voltage and also can maintains.
3, after magnetic starter modularization, mix module rack, with the fixed mount edge on the stroma of elevating mechanism control spring pin moved endSlideway in module rack vertically slides up and down, just can be neatly by the spring needle static terminal seat in controller and spring needle moved endSeat carries out Engage and disengage, reaches with control circuit and opens and closes object. Make operator there is no charged work, safety first, and maintenanceConvenient and simple, volume is little, powerful, does not have wire to be connected, controller between modular vacuum magnetic starter and module rackPower supply and relevant data acquisition, can be with the aviation pin utilization machinery blocking mechanism that opens the door, realize and the leading of module and shelfElectricity with separate. While opening the door aviation pin automatically with module disengaging, automatically connect at closing time the control device of module.
4, can, for explosion-proof occasion, be beneficial to and do flameproof enclosure, modular contactor and controller are disjunctors, with module rack itBetween without line contact, the plug push-and-pull between complete independently and main circuit, adopts mechanical latching, the front module 6 of opening the door with explosion-proof shellIndividual main contact is all separated from backbone, not charged work. To person safety.
5, the invention is integrated in contactor and controller in a module, has volume little, feature easy for installation, withTime saved peripheral cell and distribution, can greatly save the volume of complete machine when being used in combination, be convenient to transport and install and use.Each module can realize exchange, easy to maintenance. Adopt intelligentized color liquid crystal large-size screen monitors to show, user friendly operation simultaneously.
