Background technology
Domestic portable power source mainly is to realize by inverter.So-called inverter, briefly, a kind of exactly electronic equipment that low pressure (12 or 48 volts) direct current energy (battery, accumulator jar) is changed into 220 volts of alternating currents.The portable power source that inverter forms is widely used, and is seen everywhere such as vehicle-mounted inverter, household small-size inverter etc. at present in our life.
But the portable power source that generally seldom can see relatively high power is for the production of, sphere of life.Especially when using various electrical appliances, and the scene does not have available power supply, mainly be to adopt generator as power supply in the past, because the shortcomings such as its fuselage is too heavy, and is mobile dumb, and noise is large, caused inconvenience for on-the-spot work, not only working, it is passive to be absorbed in, and has affected efficient and progress, has also increased undoubtedly staff's labour intensity.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the mobile remote control supply vehicle of above-mentioned disappearance.
Summary of the invention
The purpose of this utility model is to provide the mobile remote control supply vehicle, can be applied in industrial operations job site or trade company, the resident family situation without emergency power supply.Solved the emergence power of operation field and operational environment, but secondly the progress at Effective Raise personnel's scene and operating efficiency have shortened the operating time to a certain extent, have alleviated operating personnel's labour intensity.
In order to reach above-mentioned purpose, the utility model provides following technical scheme, and the mobile remote control supply vehicle comprises inverter and the storage battery of power box and power box inside; Described power box front is provided with switch and accessory power outlet, voltage indicating instrument, and the back side is provided with the charging hole; Described power box bottom is equipped with movable pulley.
The described power box back side also is hinged with Portable draw bar.
220V AC power one side of described inverter output is installed contactor, by cut-offfing of remote controller control contactor.
In the described power box pressurizer is housed, earth leakage protective device also is housed simultaneously.
Compared to prior art, the beneficial effects of the utility model are: the emergence power that has solved operation field and operational environment, but secondly the progress at Effective Raise personnel's scene and operating efficiency have shortened the operating time to a certain extent, have alleviated operating personnel's labour intensity.Can be applied in industrial operations job site or trade company, the resident family situation without emergency power supply.

Embodiment
Relevant detailed description of the present utility model and technology contents cooperate description of drawings as follows, yet accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
According to Fig. 1, shown in Figure 2, the utility model mainly is comprised of power box 1, movable pulley 2, switch and accessory power outlet 3, voltage indicating instrument 4, Portable draw bar 5, charging hole 6, described power box 1 inner installation power inverter and storage battery, with the 48V direct current that storage battery provides, convert the alternating current of 30kHz-50kHz, 220V to; The bottom of power box 1 is provided with movable pulley 2, and the front of power box 1 is provided with switch and accessory power outlet 3, voltage indicating instrument 4, is provided with Portable draw bar 5 at the back side of power box 1.
The power inverter of 2000 VA is housed in the power box, the 48V direct current that storage battery can be provided, convert alternating current about 30kHz-50kHz, 220V to by high-frequency PWM (pulse-width modulation) switch power technology, utilize the technology such as bridge rectifier, filtering, pulse-width modulation and switch power output, convert the alternating current about 30kHz～50kHz, 220V the alternating current of 50Hz, 220V to, adopt friendship-ac frequency converter the 220V alternating current to be become the alternating current of 380V.Draw simultaneously 12V, 24V, 36V, 48V direct current socket is available, the 220V power supply can pass through the remote controller radio operation, uses at a distance more convenient.4 storage batterys of portable power source internal series-connection can use for a long time, are provided with charging device, can directly charge to storage battery.
Pressurizer is housed in the power box, guarantees the stable of output voltage, earth leakage protective device also is housed simultaneously.
During concrete the application, with 4 joint 12V storage battery tandem compounds, the assembled battery both positive and negative polarity is correctly accessed inverter 48V input and charging terminal, draw simultaneously 12V, 24V, 36V, the 48V voltage source is available, and access voltmeter real-time monitored direct voltage output value.The 220V alternating current source of inverter output is installed contactor, by cut-offfing of remote controller control contactor, reaches the purpose of Remote operation.Incorporate frequency converter at 220V alternating current outlet side, exportable 380V voltage.Simultaneously, 220V, 380V AC are incorporated respectively voltmeter into, real-time monitored alternating voltage output valve.
Power voltage of the present utility model is mainly realized by inverter.It is main pulse-width modulation circuit that inverter circuit mainly adopts TL494 or KA7500 chip, the 48V direct current that storage battery etc. can be provided, convert alternating current about 30kHz-50kHz, 220V to by high-frequency PWM (pulse-width modulation) switch power technology, utilize the technology such as bridge rectifier, filtering, pulse-width modulation and switch power output, convert the alternating current about 30kHz～50kHz, 220V the alternating current of 50Hz, 220V to, adopt frequency converter the 220V alternating current to be become the alternating current of 380V.
The plug of temporary electricity device is inserted to the interchange input in portable power source front, opens master switch, D.C. voltmeter shows normal, beats to co-bit exchanging output switch subsequently, and A.C. voltmeter shows that the temporary electricity device can use about normal voltage 220V.When power consumption equipment was distant, available remote controller disconnected and exchanges the out-put supply switch behind the interchange output switch that closes, and after far-end connected power consumption equipment, remote control was connected the AC power output switch and got final product electricity consumption.
