Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 has shown the structural representation according to the test macro of the uninterrupted power source that contains super capacitor of an embodiment of the present utility model.
According to the test macro that contains the uninterrupted power source of super capacitor of the present utility model, described test macro comprises:
AC power be used for to described ultracapacitor charging, and to the electrical load power supply, AC power is the normal power source of 220v usually, can connect by plug connection or common construction.
Ultracapacitor, its feed circuit with described AC power are in parallel, as the standby power supply of described AC power; Ultracapacitor is generally the bank of super capacitors of a plurality of series connection, and its final voltage can be 36v, also can be 48v.In parallel with the feed circuit of described AC power, thereby when AC power is cut off the power supply, can be as the short-term standby power supply of AC power.There are characteristics such as charging is fast, discharge is fast, and the life-span is long in ultracapacitor, is specially adapted to situations such as data on file or brake hard.
AC/DC converter, it links to each other with described AC power, is used for converting the alternating current that described AC power is sent to direct current; Can also play simultaneously the effect of transformation.
The selectivity seal, it is arranged between described ultracapacitor and the described AC power, is used to prevent that described ultracapacitor is to described AC power direction output electric energy; This seal is unidirectional insulation, and promptly AC power can be connected to the ultracapacitor power supply, but ultracapacitor is then shielded by this selectivity seal to the circuit network power supply of AC power.Therefore, the selectivity seal can't influence the ultracapacitor charging.
Transistor circuit, one end ground connection, the other end is connected between described AC/DC converter and the described selectivity seal; Comprise transistor in the transistor circuit, usually transistor is in unsaturated state, just do not connect transistor circuit, transistor circuit is in off-state, in test process, transistor circuit can be in the very of short duration time (time between first schedule time described later and second schedule time) connect, be generally tens microseconds.After transistor circuit was connected, the energy of AC power can mainly discharge by transistor circuit, thereby causes the input voltage of electrical load to decline to a great extent.Therefore the input voltage (second reference voltage described later) after can recording this and descending.And if this moment, the selectivity seal broke down, promptly can two-wayly conduct, because the voltage of ultracapacitor is higher, ultracapacitor then must take place to ac power supply then, the input voltage condition with higher takes place.Like this, controller can measure the input voltage of this moment greater than second reference voltage, can determine that thus fault has appearred in the selectivity seal.
Test cell, it comprises controller, timer, actuator and signal generator, the time signal that described controller sends according to described timer is controlled described transistorized switch, and carries out certain operation according to the described actuator of signal controlling that described signal generator sends.For example carry out shut-down operation, brake operating is perhaps carried out the operation of changing the selectivity seal.
Described test macro also is provided with the overcurrent protection circuit, one end ground connection, and the other end is connected between described AC power and the described AC/DC converter.The overcurrent protection circuit is in order to protect AC/DC converter to avoid the infringement of commercial electricity consumption peak value fluctuation.
Described AC/DC converter has the transformation function, and the alternating current of the 220v that described AC power can be sent converts the direct current of 48v to.
Described test macro also is provided with choking coil, and it is arranged between described AC/DC converter and the described selectivity seal.Choking coil can limit electric current, the components and parts on the entire circuit such as protection selectivity seal, electrical load.
Described selectivity seal is a diode.Diode is a kind of device of typical unidirectional conducting.
Also be provided with variable resistor in the described transistor circuit, itself and described transistor series.By variable-resistance adjusting, can determine when transistor is saturated (during conducting), by the electric current of transistor circuit, and the decline degree that can control the input voltage of electrical load.If it is higher that variable resistor is adjusted to resistance value, then input voltage decline degree is lower, and is less to the shock effect of diode so.
Described controller is set first reference voltage and second reference voltage, described first reference voltage and second reference voltage all are lower than the ratings of described primary power to the input voltage of described electrical load, when described signal generator reaches described first reference voltage at described primary power to the input voltage of described electrical load, send first signal, test beginning this moment, and described timer picks up counting; When described timer timing to the first during the schedule time, send very first time signal, this moment, the controller oxide-semiconductor control transistors was saturated, described timer continues timing to the second schedule time, send second time signal, this moment, controller detected described primary power to the input voltage of described electrical load, if described input voltage greater than described second reference voltage, then described signal generator sends the signal of caution system mistake.Wherein first reference voltage often is lower than second reference voltage.When electric system was just started working, input voltage was in the state of continuous rising, when reaching first reference voltage, promptly began test.Send the signal of caution system mistake when signal generator after, controller is then controlled actuator and is taked concrete action to deal with the mistake of selectivity seal.
Before described timer timing arrived for first schedule time, described input voltage had reached described ratings.
Mistiming between described first schedule time and described second schedule time is not more than 100 microseconds.
Comprise accident brake in the described test macro, when described controller finds that there is fault in described selectivity seal, start described accident brake.
Although embodiment of the present invention are open as above, but it is not restricted to listed utilization in instructions and the embodiment, it can be applied to various suitable the field of the invention fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the present invention is not limited to specific details and illustrates here and describe.
