Embodiment
Three kinds are mainly contained: contact switching time: measure the time to second group of main contact closes standby power supply from first group of main contact disconnects conventional power supply according to the time that existing national standard dual power supply will detect; Total actuation time: measure be monitored to deviation from principal current moment time to main contact closes standby power supply and the time delay sum specially introduced; Return switching time: from conventional power supply recover completely normal instantaneously add the time delay specially introduced to one group of main contact time closed the moment of conventional power supply.Therefore the present invention carries out timing for above-mentioned three kinds of times respectively, more accurately, conveniently.
In Fig. 1-2, the present invention exports conventional power supply to be connected load with standby power supply to signal output apparatus 20 respectively after power supply carries out pressure regulation by pressure regulation transforming circuit 10; Conventional power supply and A, B, C phase of standby power supply be provided with signal plate 1, signal plate 2, signal plate 3, signal plate 4, signal plate 5, signal plate 6 and be connected relay K A1 respectively, KA2, KA3, KA4, KA5, KA6 gather and respectively pass to signal control circuit 30 with the break-make situation of load, signal control circuit 30 controls electrical secondmeter 1 in timing displaing circuit 40, electrical secondmeter 2, electrical secondmeter 3 timing.Wherein pressure regulation transforming circuit 10 is primarily of pressure regulator (T1 ~ T6) and transformer (TC1 ~ TC6) composition, be used for controlling main circuit voltage levels, isolating switch (QF1) controls main circuit power, isolating switch (QF2 ~ QF9) controls each road on/off, pilot lamp (H1 ~ H8) indicates each phase power supply to show, and voltage table (PV1 ~ PV6) is for showing each road voltage.Signal output apparatus 20 is the load in the load access signal output apparatus of dual power supply, carrys out pilot relay (KA1 ~ KA6), output signal to provide relay (KA1 ~ KA6) by signal plate testing circuit electric current.Signal control circuit 30 completes the control to circuit phase shortage and electrical secondmeter by the break-make pilot relay of isolating switch.Timing displaing circuit 40 provides each contact signal by control circuit, and when each stopwatch circuit is connected, electrical secondmeter starts timing, and stop timing during disconnection, QF12 is for returning detector switch switching time.
Concrete, tested dual power supply is commonly used power supply, standby power supply and load and is linked in circuit by the present invention, is connected respectively with conventional power supply (Z-A, Z-B, Z-C, Z-N), standby power supply (B-A, B-B, B-C, B-N) with load A, B, C, N.When starting to detect, first closed QF1 and SB0 control KM0 starts shooting, first closure time detector switch QF11, prepare to close phase shortage switch QF10 when detecting and make KM1-1 disconnect conventional power supply A phase, now KM1-2 connects, dual power supply because of phase shortage start conversion, electrical secondmeter 1 starts timing.
When dual power supply commonly use power supply main contact disconnect completely time, signal plate 1, signal plate 2 and signal plate 3 detect that in circuit, no current passes through to relay K A1, KA2 and KA3 signal, now KA1-1, KA2-1 and KA3-1 are closed, signal plate 7 makes KA7-1 close must electricly to relay K A7 signal, and electrical secondmeter 2 starts timing.
When dual power supply standby power supply is completely closed, signal plate 4, signal plate 5 and signal plate 6 detect circuit ON, to relay K A4, KA5 and KA6 signal, KA4-2, KA5-2 and KA6-2 are disconnected.After KA4-2, KA5-2 and KA6-2 all disconnect, signal plate 10 testing circuit dead electricity makes KA8-1 disconnect to relay K A8 signal, now electrical secondmeter 1 and electrical secondmeter 2 stop timing, and total actuation time and contact show switching time respectively on electrical secondmeter 1 and electrical secondmeter 2.
Detection returns switching time, first closedly returns detector switch QF12 switching time, and at the end of detection total actuation time, KA1-1, KA2-1 and KA3-1 are closed, and now signal plate 11 testing circuit obtains and electricly to relay K A9 signal, KA9-2 closed.After disconnecting phase shortage switch QF10, signal plate 8 detection line dead electricity makes KM1-1 close to KM1 signal, and now primary power recovers normal, and simultaneously electrical secondmeter 3 starts timing.When conventional power supply main contact closed moment, signal plate 1, signal plate 2 and signal plate 3 testing circuit obtain electric, to relay K A1, KA2 and KA3 signal, after KA1-1, KA2-1 and KA3-1 all disconnect, signal plate 11 detection line dead electricity makes KA9-2 disconnect to relay K A9, now electrical secondmeter 3 stops timing, returns and shows on electrical secondmeter 3 switching time.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical solution of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
