Brief description
Fig. 1 is the structural representation of the present invention.
In figure：Accumulator 1, change-over circuit 2, power output circuit 3, main circuit 4, test circuit 5.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further illustrated：
As Fig. 1, a kind of relay-protection tester of not power-off, including power-supply system and test system, power-supply system includes
Accumulator 1, change-over circuit 2, power output circuit 3, test system includes main circuit 4, test circuit 5, described accumulator 1
Connect civil power, accumulator includes 24～12V/50A adjustable charger and the 12.80A h lead accumulator of two concatenations.Energy storage
Circuit 1 connects change-over circuit 2, power output circuit 3, and main circuit 4 is connected with power output circuit 3, and test circuit 5 passes through transformation
Rectification unit is connected with power output circuit 3, and the power amplification unit of test circuit 5 connects relay.
When line voltage is working properly, civil power (220V) passes through adjustable charger and charges to battery power-supply system, with
When starting relay K1 adhesive, R1 and VZ1, VZ2 carry out partial pressure sampling to battery+24V voltage, and sampled voltage Vo passes through
R2, VD3 are added to V1 base stage, make V1 be in Linear Amplifer state, V2, V3 depth saturation, DC control relay K adhesive ,+24V
Voltage delivers to inverter V+ end by K, K1, and inverter works, and exports 220V sine voltage, and latching relay K2 inhales simultaneously
Close.
When civil power power-off, K1 disconnects, and defeated people voltage+24V is constant at the beginning, and K continues adhesive, due to the self-locking action of K2 ,+
24V still normally delivers to inverter.After a period of time, cell voltage begins to decline, and Vo follows and declines, and V1 conducting weakens, V2 liter
High；After battery tension drops to 22V, V2 exits saturation and enters people's Linear Amplifer, and V3 declines rapidly；V3 feeds back to V1 by R7
Base stage is so that V2 continues to raise.V2, V3 end rapidly, and K disconnects, and+24V the direct current that inverter delivered to by battery is cut off, inversion
Device quits work, and K2 disconnects simultaneously.After inverter quits work, due to the effect of battery internal e.m.f., battery is extensive quickly
Multiple 24V voltage, as normality, V2, V3 saturation, K adhesive.
Now K1, K2 all disconnect, and+24V cannot reach inverter, and inverter does not work, thus protecting battery.Only
After city power recovery is normal, K1 adhesive, inverter could work, and now charger charges to battery.
Main circuit includes double carbon-brush voltage regulator, isolating transformers, and main circuit connects power supply and enters double carbon-brush voltage regulator inputs,
