Description
Technical field：
This utility model belongs to the direct current cabinet part in the power supply unit field of stable dc power supply, and in particular to be one
Plant the alternating current-direct current screen for improving battery discharging module.
Background technology：
Traditional direct current cabinet battery when needing to detect discharge performance, generally discharged using resistor, is passed through by electric discharge
The heating of resistor, converts electrical energy into heat energy.This discharge mode has the disadvantage that：Due to substantial amounts of heat consumption, cause
Ambient temperature is raised, and is easily caused fire and personal safety hidden danger, and reduces the insulation effect of surrounding devices, especially
The products such as plastics, rubber, such as cable；Cause the huge waste of energy, especially the resistance such as large power plant, telecom hub office with
Change itself resistance for temperature can also change, therefore discharge current can not keep constant measurement result to accumulator
Cause larger deviation；Conductive discharge can not possibly realize continuously adjusting for discharge current, therefore the characteristic to battery can not be carried out
Accurately judge；Due to by the way of manual discharge, high labor intensive is affected by human factors many, easily causes overdischarge etc.
Discharge accident problem.The storage of battery power cannot be also detected simultaneously.
The content of the invention：
For the defect that prior art is present, the purpose of this utility model is to provide and a kind of can overcome changing for drawbacks described above
Enter the alternating current-direct current screen of battery discharging module.
The technical scheme in the invention for solving the technical problem is：A kind of friendship for improving battery discharging module
Direct current cabinet, it is critical only that the alternating current-direct current screen includes control assembly, DC charging component, accumulator, output precision and electric discharge mould
Block, disconnecting switch that described discharge module includes being sequentially connected, LLC full-bridge controlled resonant converters, half-bridge inversion circuit are described
Disconnecting switch is connected to control assembly.
Described control assembly includes the electric energy metering module that can count electricity.Electric energy metering module can be calculated and be shown
The capacity of battery, to judge whether battery needs to change.
Described disconnecting switch is connected to control assembly by RS485 ports
The alternating current-direct current screen for improving battery discharging module of the present utility model is using connecting an electric energy meter in discharge module
Amount module, by the calculating of discharge capacity, shows battery remaining power, to facilitate the advantage for judging battery efficiency.
Description of the drawings：
Fig. 1 is this utility model structural representation.
Specific embodiment：
As shown in figure 1, it is a kind of improve battery discharging module alternating current-direct current screen, the alternating current-direct current screen include control assembly,
DC charging component, accumulator, output precision and discharge module, disconnecting switch that described discharge module includes being sequentially connected,
LLC full-bridge controlled resonant converters, half-bridge inversion circuit, described disconnecting switch are connected to control assembly.
Described control assembly includes the electric energy metering module (not shown) that can count electricity.Electric energy metering module can
To calculate the capacity for showing battery, to judge whether battery needs to change.
Described disconnecting switch is connected to control assembly by RS485 ports
Battery discharging module adopts active inversion feedback discharge mode, is into exchange the DC power conversion of accumulator
Electricity, feeds back in AC network, and energy is recycled.Consume energy discharge mode relative to resistance, more energy-conserving and environment-protective, and not
Amount of heat can be produced, it is more comfortable for operator, it is safer for equipment.Described LLC full-bridge controlled resonant converters,
Half-bridge inversion circuit is prior art.
Active inversion feedback discharge module adopts DC-DC-AC link structures, input dc power to become by LLC full-bridges resonance
Parallel operation, isolation and amplifier 760V or so direct current, then by half-bridge inversion circuit, 760V direct currents are converted to same with frequency with alternating current bypass
Mutually and with width voltage.Equivalent to an ac current source when active inversion module works, according to the electric current of setting by DC energy
Be converted to AC energy to feed back in electrical network.
Direct current cabinet discharging device realizes active inversion (when converting means exchanges side joint using high-frequency power electronic technology
On electrical network, DC inverter is fed back to electrical network up into the alternating current of same frequency.
Direct current cabinet discharging device adopts energy feedback technology, in fact, in the equipment using frequency control, electric energy
It is reconverted into what heat energy had been wasted generally by dynamic braking resistance, using Technics of Power Electronic Conversion technology, which is main
Effect is exactly to use the produced regenerative electric energy in running of the said equipment, and is converted to synchronous AC energy
Electrical network is transmitted back to, the effect of economize on electricity is played.Energy is returned to into electrical network, energy saving.
There is direct current cabinet discharging device the unidirectional current of perfect protection system-inversion to be locked with the two-stage of AC network
Mutually make output cyclical signal equal with input periodic reference signal frequency, and phase contrast keeps constant process.Two-stage is locked
Phase --- same frequency same phase, can avoid situation about overturning because of phased power inverter during intermittent power-off, and system is absolute
Aspergillus ficuum is designed, and grid cut-off, disturbance are not had inversion and overturn phenomenon；In good time invariable power design, changes in AC network
While ensure input current constant control.
The waveform of inverter output is sine wave, and power factor (PF) is close to 1, to AC network no-harmonic wave pollution and idle biography
Pass.
