Description
Technical field
The utility model is related to a kind of inverter, specifically a kind of inverter for being conveniently replaceable insurance high security.
Background technology
Inverter is that direct current energy (battery, accumulator jar) is transformed into alternating current (generally 220V, 50Hz sine wave).It
It is made up of inverter bridge, control logic and filter circuit.It is widely used in air-conditioning, home theater, electric wheel, electric tool, seam
Thread machine, DVD, VCD, computer, TV, washing machine, smoke exhaust ventilator, refrigerator, video recorder, massager, fan, illumination etc..Abroad
Because the outgoing work higher of the popularity rate of automobile or out on tours are that available inverter connection battery drives electrical equipment and various instruments
Work.The vehicle-mounted inversion exported by cigar lighter is 20W, 40W, 80W, 120W to 150W power requirements.Larger power is inverse again
Variable power source will be connected on storage battery by connecting line.The output end that household electrical appliance are connected to power supply changeover device can just be made in automobile
Use various electrical equipment.Usable electrical equipment has：Mobile phone, notebook computer, DV, camera, illuminating lamp, electric razor
Knife, CD player, game machine, palm PC, electric tool, car refrigerator and various tourisms, camp, medical first aid electrical equipment etc..
Inverter is that direct current energy (battery, accumulator jar) is transformed into alternating current (generally 220v50HZ sines or side
Ripple).Popular says, inverter is a kind of device that direct current (DC) is converted into alternating current (AC).It is patrolled by inverter bridge, control
Collect and filter circuit composition.It is widely used in air-conditioning, home theater, electric wheel, electric tool, sewing machine, DVD, VCD, electricity
Brain, TV, washing machine, smoke exhaust ventilator, refrigerator, video recorder, massager, fan, illumination etc..Briefly, inverter is exactly one
Plant and low pressure (12 or 24 volts or 48 volts) direct current is changed into 220 volts of electronic equipments of alternating current.Because we are typically 220
Volt AC rectification becomes direct current to use, and the effect of inverter is in contrast, therefore and gains the name.We are in one
The epoch of " movement ", mobile office, mobile communication, mobile leisure and amusement.In mobile state, people are not only needed by electricity
Pond or the low-voltage DC of storage battery supply, while with greater need for our indispensable 220 volts of alternating currents in surroundings, inversion
Device can just meet our this demand.
Present inverter is widely used in our life, but most inverter structure is more fixed now,
Wherein fuse is generally fixed to inside, and because the voltage and current amplitude of inverter is big, fuse often easily burns out, existing
Inverter fuse change difficult, it is impossible to meet present use demand.
