Description
Technical field
The utility model relates to a kind of automatic change-over.
Background technology
Three classes have been experienced in the production development of electrical source exchange system class substantially: contactor class, breaker of plastic casing class/load-break switch class, integral type automatic transfer switching electric appliance class.
Contactor class, this type of electrical source exchange system is taking contactor as switching execution unit, handoff functionality completes control function with auxiliary reclay or logical control module composition secondary circuit, be generally nonstandard product, shortcoming is that major loop contactor need of work secondary circuit is switched on for a long time, easily produce the faults such as temperature rise heating, contact adhesion, coil burnout, because be nonstandard product, its composition components and parts are more, product quality is restricted by components and parts, manufacturing process, fault rate is higher, is now replaced by new product gradually.
Breaker of plastic casing class, this type of electrical source exchange system is taking mold cased circuit breaker as switching execution unit, handoff functionality completes with ATS automatic control unit, there are machinery and electrical interlocks, perfect in shape and function, good operation performance, high life, composition components and parts are less, easy for installation, this generic CB level transfer switching equipment, by two breakers as electric current disjunction unit, and be equipped with current-release device, possesses certain protective capability, connection/the breaking capacity of breaker is high more a lot of than relay, when this series products stable state, kept by frame for movement, because breaker is with the difference of load-break switch itself, effect under over-current condition is not as PC level product.
Load-break switch class; load-break switch type transfer switching equipment is on the basis of two load-break switch, to install that motor-operating mechanism, mechanical chain mechanism, automatic control unit etc. are integrated to be assembled additional; the disjunction unit of electric current is load-break switch; its contact arc-extinguishing system designs with an electric arc requirement of disjunction; do not possess the defencive function of circuit; this series products belongs to PC level product; it is because having adopted the acceleration mechanism of spring energy-storage, instantaneous relase; can quick-make, point deenergizing or carry out the conversion of circuit, product operation dependable performance.
Integral type automatic transfer switching electric appliance class; this type of power conversion system is to integrate switch andlogic control; without additional controller; really realize the automatic change-over of electromechanical integration, the contact system of this type of electrical source exchange system product adopts " single-pole double throw " design, is Uniting manufacture; volume is little; simple in structure, this product does not possess current protecting function, belongs to PC level transfer switching equipment product. This series products is smaller general conversion time; switching over drives and adopts motor to drive; switch steadily reliable; operator motor drives only has electric current to pass through in switching over moment, when stable state without providing operating current, obvious energy conservation; product is without temperature rise heating, contact adhesion, coil burnout phenomenon; switch band Organic Electricity interlock, can realize and haul oneself willingly into runback, haul oneself willingly into not runback, decompression, under-voltage, open-phase protection, manauto conversion, time delay control etc., is electrical source exchange class main product.
Current existing automatic change-over can not carry out the switching of power supply, uses inconvenient operation, and structural safety performance is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, easy for installation, when power supply breaks down, self and supply line is protected, and can carry out the automatic change-over of conversion automatically to stand-by power supply again.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of automatic change-over, comprise housing, operating grip, energy-stored spring and flying wheel, described operating grip is located at housing one side, described energy-stored spring and flying wheel are located in housing, described operating grip, energy-stored spring and flying wheel are in transmission connection successively, on described flying wheel, be provided with linkage, described linkage and flying wheel are hinged, described linkage end is connected with moving contact and lower moving contact, described upper moving contact and lower moving contact front end are provided with static contact insert row, described static contact insert row two ends are provided with Petersen coil, described static contact insert row front end is electrically connected with outlet row.
As preferably, described static contact insert row and outlet row are respectively arranged with three, conveniently switch different power supplys.
As preferably, on described housing, be provided with draw-in groove, conveniently install fixing.
As preferably, between described upper moving contact and lower moving contact, be provided with latch lever, in maintenance, moving contact and lower moving contact can not close a floodgate simultaneously.
As preferably, described upper moving contact is connected by latch lever with lower moving contact, keeps easy installation and reliable.
The beneficial effects of the utility model are: the operating grip of setting keeps affected safe and reliable, energy-stored spring is convenient carries out transmission by flying wheel linkage, it is easy for installation that draw-in groove on housing keeps, Stability Analysis of Structures, the electric arc that Petersen coil produces can eliminate circuitry cuts or closure time, upper moving contact and lower moving contact conveniently make different power access circuits.
