Description
Technical field:
The utility model relates to the distribution board that power distribution is used, and IC is H02B.
Background technology:
At present, high-frequency switch rectifying power supply has been widely used in fields such as telecommunications, electric power, oil, in case electric main breaks down, high-frequency switch rectifying power supply will lean on its standby battery group to keep power supply to DC load, the discharge time of batteries is limited, and the president does not keep discharge the time.Frequent or AC-powered is unstable, the area of frequent outage in the AC network fault, batteries discharges and recharges the useful life that has greatly shortened batteries continually.In addition, the complete machine decreased performance that high-frequency switch rectifying power supply starts regularly, unexpected shutdown also can make high-frequency switch rectifying power supply is difficult to guarantee the stable operation to direct current supply.
The sun-generated electric power power supply is extensively popularized in recent years, is applied to different field and occasion, for the area that AC network does not cover, is a desirable energy source.But when no solar irradiation or solar irradiation deficiency, the power supply needs that the generating of solar energy photoproduction volt just can't be satisfied power consumption equipment can only lean on the solar energy-electric energy short-term of batteries deposit to keep power supply.
For the operation that guarantees that direct current supply is reliable, stable, conventional method is to adopt the electric main power supply to be equipped with batteries more in addition as backup, when AC network is cut off the power supply, replaces the AC network power supply by batteries.
Though the generating of solar energy photoproduction volt can utilize solar power generation, and becomes transform light energy electric energy to be stored in the storage battery, solar power generation is subject to time, season and climatic influences.When no solar irradiation or when overcast and rainy, the solar panel energy output is with regard to wretched insufficiency even can't generate electricity at all, can only keep the operation of power consumption equipment by battery discharging.AC network is being arranged, but AC network electricity shortage, unsettled area, relying on the solar power generation power supply promptly to cause the waste of AC network resource merely, nor economical.
See that Fig. 1 is existing sun-generated electric power power supply schematic diagram, it is made of solar energy photocell board 1, DC distribution control unit 2, batteries 3.Wherein, the DC distribution control unit adopts D.C. contactor more.Solar energy photocell board 1 converts solar energy to electric energy, and convert stable direct current 48V to by DC distribution control unit 2 and be stored in the batteries 3, and to power consumption equipment 4 power supplies.
See that Fig. 2 is existing high-frequency switch rectifying power supply power supply schematic diagram.The 220V alternating current is delivered to high-frequency switch rectifying power supply 5 through A.C. contactor 6, and after high-frequency switch rectifying power supply 5 converted the 48V direct current to, part of direct current directly offered power consumption equipment 4,3 chargings of another part accumulators group.Existing high-frequency switch rectifying power supply adopts 220V to exchange the direct voltage that converts fluctuation through bridge rectifier to more, the booster circuit of forming via inductance, power switch pipe, speed-sensitive switch diode, electrochemical capacitor boosts to the 400V direct voltage again, the high-frequency chopper of being made up of four power switch pipes and high frequency transformer is pressed the 400V direct current high-frequency ac square-wave voltage that converts 100V to again, become to contain the direct current pressure of high frequency ripple composition again through the high-frequency rectification diode rectification, after form 48V direct voltage stably after the filter inductance filtering.It is the permanent power-type of 48V for the 2800W output voltage that high frequency switch power is selected power output for use, and model is YRM48V2800W.
With regard to present situation, area in Alternating Current Power Supply instability, AC network power supply quality difference, realize that unattended direct current supply station does not also have a kind of desirable, reliable and practical supply unit that highly reliable direct current can be provided, guarantee direct-flow electricity utilization apparatus operation reliable, steady in a long-term.
Summary of the invention:
The purpose of this utility model provides a kind of direct current supply power distribution cabinet stable, that do not have interruption of powering, a kind of high-frequency switch rectifying power supply and solar energy mixing power distribution cabinet, it is that existing sun-generated electric power power supply and high-frequency switch rectifying power supply power supply are integrated, and realizes that the different DC power supply of two-way is the power supply of power consumption equipment and batteries jointly.High-frequency switch rectifying power supply and solar energy mixing power distribution cabinet, form by A.C. contactor, high-frequency switch rectifying power supply, solar energy photocell board and battery pack, the 220V alternating current is through A.C. contactor tremendously high frequency Switching Power Supply, after the 220V alternating current converted to the direct current that is nominally 48V, output to the DC distribution control unit; Solar energy is after solar energy photocell board converts direct current to, be input to the DC distribution control unit, the DC distribution control unit is united-is managed and control the 48V direct current from high-frequency switch rectifying power supply, solar energy photocell board and batteries, realize the mutual conversion output of solar energy and alternating current, for the power consumption equipment power supply and at any time to battery charging.
With under the pattern, solar energy photocell board utilizes solar power generation to provide direct current power for direct-flow electricity utilization apparatus the solar energy master, charges to the electric power storage group simultaneously; When no solar irradiation or overcast and rainy solar power generation deficiency, offer direct-flow electricity utilization apparatus through the batteries discharge, when battery discharging is arrived to a certain degree, change by electric main through high-frequency switch rectifying power supply, for direct-flow electricity utilization apparatus provides direct current energy.
With under the pattern, generally convert direct current to through high-frequency switch rectifying power supply the electric main master by electric main, for power consumption equipment provides direct current energy, accumulators group charging simultaneously; When electric main interrupts because of supply of electric power appears in the electrical network reason, change into by batteries and provide electric power to direct-flow electricity utilization apparatus, when battery discharging is arrived to a certain degree, and this moment grid alternating current when not restoring electricity as yet, commentaries on classics is generated electricity by solar panel, provides direct current energy for battery charging with to direct-flow electricity utilization apparatus simultaneously.
High-frequency switch rectifying power supply of the present utility model, solar energy mixing power distribution cabinet; can provide continuously to direct current 24V or 48V communication equipment or direct current cathodic protection equipment, stablize, direct current energy reliably, especially extremely unstable in alternating electromotive force supply scarcity or alternating current supply, direct-flow electricity utilization apparatus operational support and the demanding occasion of power supply are used.
