Description
Technical field the utility model relates to a kind of power transfer device, especially automatic throw-in equipment of emergency power supply.
Background technology supplies in the distribution electric power system, the industrial enterprise that should not cut off the power supply and cinema and sports tournament place, and people often use duplex feeding in order to ensure not cutting off the power supply, and promptly when working power decompression or outage, immediately it is switched to stand-by power supply.Switching mechanism many by working power auxiliary contact or add low-voltage relay, time-delay relay and provide the actuating power supply etc. of electric power to constitute to the actuating coil of the switch of these contacts or relay, put into operation to start stand-by power supply directly or indirectly.But, this mechanism exists weak point, at first, switching between working power and stand-by power supply needs the action successively of working power switch and Backup Power Switch, and as single stroke time of the various AC-DC relay of switch or A.C. contactor or AC circuit breaker or on-load switch or vacuum circuit-breaker etc. all up to 20～50 milliseconds, make the input of stand-by power supply lag behind 40～100 milliseconds of working power power-cut time, Chang time like this, totally unfavorable to load, particularly to inductive load, will be long because of power-off time, busbar voltage and rotating speed of motor all descend excessive, after stand-by power supply closed, the self-starting current of motor unit was very big, and busbar voltage may be difficult to recover; Secondly, above-mentioned switch all exists 10% decentralization because of foozle, and this just can make the input of stand-by power supply lag behind more again; Once more, the undue input that lags behind of stand-by power supply also will make phase place, voltage and frequency between working power and the stand-by power supply produce bigger difference, and the stand-by power supply that closes this moment not only has impact to the stand-by power supply electrical network, and load is also had great impact.For addressing this problem, a kind of device that uses single-chip microcomputer in power supply switches is arranged, it is to settle the monitor that is electrically connected with single-chip microcomputer respectively on working power and stand-by power supply, so that when single-chip microcomputer abnormal conditions occur in working power, with working power only in backup power source voltage and bus residual voltage at phase angle, frequency differs and hour to switch to stand-by power supply, and in the time can not switching, automatically transfer the switching at a slow speed of differentiating or declare residual voltage and long delay the same period to, and in the process of electric voltage dropping, get rid of the non-important load of part, be beneficial to the self-starting of important motor, as commercially available microcomputer stand-by power supply apparatus for fast switching; ; this device has covered a sine wave at least because of the single stroke time of closing or dividing of existing switch; and its decentralization is also up to 2～5 milliseconds; even very accurate to the phase angle of bus residual voltage, frequency measuring and calculating; also will can't accurately control and bus residual voltage stand-by power supply on phase angle, frequency differ than hour switching because of the operate time and its decentralization of switch; therefore, still can not fundamentally overcome the defective of above-mentioned switching mechanism.In another part Chinese patent CN of the applicant 2575833Y (day for announcing is on September 24th, 2003), a kind of Switching Permanent Magnetic Actuator was described once, it adopts a metal dish or bi-metal plate places between a pair of coil or a coil places between two cards of a bi-metal plate, and the drive rod on metal dish or the bi-metal plate and the transmission mechanism of mechanical switch are connected to form; The magnetic flux that this device utilizes coil to produce induces vortex flow in metal dish or bi-metal plate, and the magnetic flux that this vortex flow produces is opposite with the direction of the magnetic flux of coil generation, these two electric power that rightabout magnetic flux interacts and produced, impel metal dish or bi-metal plate to move to the direction of leaving coil, thereby the driving switch body is finished the operation of combined floodgate or separating brake, it closes or time of dividing only needs below 3 milliseconds, and decentralization only is below 0.1 millisecond.Though the branch time of closing of this Switching Permanent Magnetic Actuator is shorter, but as it is used for working power switch and Backup Power Switch respectively individually, though can overcome the defective of such scheme, but have possibility to make stand-by power supply or do not switch, or close a floodgate in the deficiency of fault because of wherein a misoperation.
The summary of the invention the technical problems to be solved in the utility model is the limitation that overcomes above-mentioned various schemes, provide a kind of simple in structure, practical, use automatic throw-in equipment of emergency power supply more easily, it can be by any realization the in following four kinds of technical schemes.
