Micro computer monitoring is used for the data demonstration and dependent instruction is handed down to control unit.
The utility model inversion, feedback discharge integrated apparatus, invert function requirement in can satisfying electric power usefulness direct current and exchanging integrated no-break power unit can as its storage battery activation experimental provision, have following beneficial effect again:
1, energy-conservation
Electric energy feedback during with storage battery activation enters electrical network and carries out recycling.
2, avoid overlapping investment
After using this device, can save traditional discharge instrument, reduce maintenance cost.
3, save human cost
This device uses flexibly, mode of operation, but unattended operation has lowered human cost greatly.
4, reduce potential safety hazard
This device caloric value is little, has effectively controlled fire and life potential safety hazard.
5, improve the useful life of storage battery, reduce the second investment
This device has adopted advanced battery management pattern, can realize storage battery constant-current discharge, and maintenance effects is optimum, prolongs the useful life of storage battery.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the circuit theory diagrams of the utility model inversion, feedback discharge integrated apparatus.
Embodiment
See also Fig. 1, inversion, feedback discharge integrated apparatus, AC load is connected with two branch roads by relay K 3, and a branch road is bypass civil power and the relay K 1 that is linked in sequence, and another branch road is batteries, inversion unit and the relay K 2 that is linked in sequence.The work of control unit control inversion unit, and the closed or disconnection of relay K 1-3.Micro computer monitoring is used for the data demonstration and dependent instruction is handed down to control unit.
The utility model inversion, feedback discharge integrated apparatus have inversion and feedback discharge dual-use function.
For invert function, what the inversion unit of this device adopted is the high-frequency inversion technology, and when the bypass civil power was normal, the relay K 2 in the control unit control device disconnected, and K1, K3 are closed, and AC load is directly powered by the bypass civil power; When bypass city electrical anomaly, control unit control allows relay K 1 disconnect, and K2, K3 are closed, and AC load is powered by inversion unit, to satisfy the AC load normal operation; After the bypass civil power was replied normally, control unit was automatically controlled relay K 2 is disconnected, and K1, K3 are closed, reply and power to AC load with the bypass civil power.
For the feedback discharging function, when electric power with direct current when storage battery in exchanging integrated no-break power unit need to activate, control unit control allows K3 disconnect, K1, K2 are closed, and the output voltage waveforms of modulation inversion unit is synchronous with the voltage waveform of bypass civil power, the direct current of storage battery is converted in the electrical network that alternating current is fed back to the bypass civil power goes, in order to make the storage battery activation effect optimum, feedback discharge in this device is to move by the input side constant-current discharge, after the storage battery activation experiment was finished, device was understood automatic shutdown or is transferred the invert function operation to.
