Utility model content
The utility model is directed to above-mentioned problems of the prior art, there is provided a kind of movable low-pressure dual power supply conversion Device, solves customer power supply power supply in the prior art(Main power source)Power supply is confessed with emergency power generation vehicle(Stand-by power supply)Can not be effective With reference to the problem of switching.
The technical solution of the utility model is as follows:
A kind of movable low-pressure dual power supply converter, including casing, dual-power transfer switch, casing is interior to set dual power supply to turn Switch, state display lamp and alarm buzzer are changed, the outside of casing is provided with two groups of power supply terminals and one group of load terminals Son, two input terminals of dual-power transfer switch are connected with two groups of power supply terminals, dual-power transfer switch it is defeated Go out terminal with load binding post to be connected;State display lamp and buzzer mould line by copper and are connected to the two of dual-power transfer switch On secondary auxiliary contact.
The outside of described dual-power transfer switch is closed with insulation mould plate, makes dual-power transfer switch at one In the space of closing, the upper surface of the mould plate that insulate sets observation window, and observation window is corresponding with the display screen of dual-power transfer switch.
Case lid is provided with above described casing, various aids are hung with the inside of case lid.
It is furnished with universal wheel and pull bar outside described casing.
The material of described casing is aluminium sheet material, and is furnished with ground terminal.
Described two groups of power supply terminals and one group of load binding post are rain-proof binding post.
The utility model has the advantages of as follows:
1st, the material of casing is aluminium sheet material, and is furnished with ground terminal, ensures that casing grounding safety is reliable, ensures personnel's peace Entirely.It is furnished with universal wheel and handle, conveniently moving outside casing.
2nd, can be by user's main power source and power autonomous carry out automatic conversion by dual-power transfer switch, it is movable to The electric field of any required double power-supply automatic transferring, and very easily move at the scene, do not limited by any place System, solves the trouble that manual switching is brought, and improves and protects electric timeliness and level, shortens power off time, it is ensured that power supply Reliability, improve power supply quality.
3rd, by dual-power automatic switching instead of it is original manually switch, greatly improve power supply reliability and safety Property, original switching time was foreshortened within 3 seconds, so as to reach uninterrupted power supply, and prevents all kinds of burst accidents from influenceing user Important electricity consumption, this device can meet one, the two class power load requirements of support, and can easily be moved to needs and protect showing for electricity , ability and level that electric company protects electricity to special electricity consumption place are improved, the power transmission of falling of artificial incorrect operation generation is prevented, realizes It is intelligent and rapid in low-voltage dual power transfer process.
Brief description of the drawings
Fig. 1 is the inside schematic diagram of the utility model dual-power transfer switch.
Fig. 2 is casing inner structure schematic diagram of the present utility model.
Wherein, 1- main power sources binding post, 2- stand-by power supply binding posts, 3- load binding posts, 4- pull bars, 5- are universal Wheel, 6- dual-power transfer switch, 7- alarm buzzers, 8- state display lamps, FU1-FU6- protective tubes, N1- main power sources, N2- are standby Use power supply.
Embodiment
Referring to the drawings, in conjunction with specific embodiments, concrete structure of the present utility model is described in detail.
Embodiment
As illustrated, the utility model includes casing and case lid two parts up and down, safe work device is mainly placed inside case lid Tool.
Dual-power transfer switch 6, state display lamp 8 and alarm buzzer 7 are set in casing, and the outside of casing is provided with two groups Rain-proof power supply terminal and one group of rain-proof load terminals 3, two groups of power supply terminals are main power supply terminal 1 and standby Power supply terminal 2, two input terminals of dual-power transfer switch respectively with main power source binding post 1 and stand-by power supply Binding post 2 is connected, and the lead-out terminal of dual-power transfer switch is connected with load binding post 3;State display lamp 8 and buzzer 7 mould line by copper is connected on the secondary auxiliary contact of dual-power transfer switch.
