AC power supply device

Technical field

The utility model relates to a kind of AC power supply device.

Background technology

In the prior art, Alternating Current Power Supply mainly adopts following several mode:

One, is converted to the electric main of 220V through transmission, transformation from the high-tension electricity of power plant output; This supply power mode is confined in the electrical network, in the inaccessible outlying district of electrical network, adverse circumstances, can't obtain Alternating Current Power Supply, and power supply network also causes fault through regular meeting because of a variety of causes, causes power failure.

Two, adopt small generator, alternating current directly is provided among a small circle, generator uses fuel such as diesel oil, can produce serious air pollution and noise pollution.

Three, the AC power supply device of forming with storage battery and AC inverter provides.The UPS uninterrupted power supply is to be exactly to adopt the widely used AC power supply device of this kind mode.The UPS uninterrupted power supply can be used between power supply grid and the power consumption equipment, occurs at electrical network can ensureing the safe operation of power consumption equipment under the situation of accident power-off.Its principle of compositionality is: storage battery is storage of electrical energy at ordinary times, in case outage occurs, internal unit starts immediately, and moment is converted into civil power with electricity of accumulator through inverter, continues supply arrangement to guarantee security of operation.Under situation about having a power failure, can provide alternating current to equipment, and pollution-free, but many deficiencies are arranged: 1. UPS need use storage battery; 2. UPS can not leave operation of power networks by the electrical network store electrical energy; 3. the UPS run duration is shorter; 4. the UPS price is higher.

Summary of the invention

The objective of the invention is: overcome the deficiencies in the prior art, but provide a kind of independent operating, power-on time to continue to grow, be convenient to use, safeguard simple AC power supply device.

The present invention realizes by the following technical solutions for this reason:

A kind of AC power supply device comprises AC inverter, metal air fuel cell or battery pack, and described metal air fuel cell is made of metal electrode 1, electrolyte 2, air electrode 3; The positive-negative input end of described AC inverter is connected with described air electrode 3, metal electrode 1 respectively, the direct current of described metal air fuel cell or battery pack output is converted to exchanges output.

Described metal electrode 1 is aluminium alloy or other metal alloy.

Described air electrode 3 is made of conductive copper silk screen 31, oxyphie material layer 32, waterproof ventilated membrane 33; Described oxyphie material layer 32 is attached to the both sides of described copper mesh 31, and described waterproof ventilated membrane 33 is attached to an outside of described oxyphie material layer 32, is used for described air electrode 3 and described electrolyte 2 are isolated; Described waterproof ventilated membrane 33 is through the film that mixes, distills, washs, stirs, toasts, compacting forms by polytetrafluoroethylene, emulsifying agent and acetylene black.

Described electrolyte 2 is neutral electrolytes; Described neutral electrolyte 2 is salt (NaCl) water, seawater or takes from the bitter in salt water lake; Contain potassium permanganate KMnO4 in the described electrolyte 2.

Because the realization of technique scheme, the utility model adopts metal air fuel cell and DC/AC translation circuit to constitute AC power supply device, the DC power supply of metal air fuel cell group output can be converted to alternating current, particularly the electric main of 220V, 50HZ; Its beneficial effect that brings is:

Because the power supply that uses is a metal air fuel cell, does not have any pollution, also need not lean on the electrical network store electrical energy, can be independent of operation of power networks; As long as change the metal fuel utmost point in good time, with regard to the energy continuous firing, power-on time is long; Can when having a power failure, substitute UPS, can overcome environmental limitations again, be used for the unapproachable outlying district of electrical network, adverse circumstances are directly powered.

Because as the metal air fuel cell that current source in the utility model adopts, what its metal electrode mainly adopted is aluminium alloy, chemical property is much more active than metals such as zinc, copper, iron, can produce stronger electric current, longer duration, efficient height; And electrolyte adopts is neutral electrolytes such as saline solution, seawater or bitter, its preparation, obtains all very easily, also can carry out operation and maintenance to described battery in the outlying district, is easy to apply; The copper mesh that conductive metal layer adopts can improve conductance, and the oxyphie material layer of both sides helps the airborne oxygen molecule of absorption, improves the performance of metal fuel air cell; Thereby make AC power supply device of the present utility model be more convenient for using, be easy to safeguard.
