Description

Dual output power supply

The present invention relates to a power supply device, and more particularly to a dual output power supply device.

A large number of hand tools and lighting are often required for maintenance of long-distance pipelines, cleaning and maintenance of storage tanks, etc. However, the sockets that can be provided in general places are very limited, and often cannot meet the construction requirements.

Therefore, most of the existing methods are to prepare a steam/diesel generator to provide the required power. However, steam/diesel generators not only have low energy conversion efficiency, but also generate noise and air pollution.

In addition, if the cylinder surface of a metal storage tank or large machine is inspected, only a power supply of 30 volts or less can be used for safety reasons. Therefore, whether using a general power supply or a steam/diesel generator, an additional substation or power supply line is required, which is not only inconvenient to use, but also causes the line on the construction site to be very messy and affects the safety of the construction.

Therefore, the object of the present invention is to provide a dual output power supply device that is convenient to use and has different output voltages.

Therefore, the dual output power supply device of the present invention comprises a carrying unit and a power supply unit. The power supply unit includes a power input mechanism at the load unit, a first power supply mechanism electrically connected to the power input mechanism to output a first power source, and a first power supply connected to the power input mechanism to output a second power source. The second power supply mechanism has a different voltage between the first power source and the second power source.

The utility model has the beneficial effects that the first power supply mechanism and the second power supply mechanism that can output different voltages and the second power supply are integrated on the carrying unit, which is convenient for use and can also shorten preparation before construction. time.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is a side view illustrating the first power supply mechanism of the embodiment of the novel dual output power supply device; A side view illustrating the second power supply mechanism of the embodiment; and FIG. 3 is a schematic view illustrating the power supply unit of the embodiment.

Referring to Figures 1 and 2, an embodiment of the dual output power supply device 2 of the present invention includes a carrier unit 3 and a power supply unit 4. The carrying unit 3 includes a platform 31 having a plurality of wheels 311, a receiving box 32 disposed on the platform 31, and two axle posts 33 respectively located on opposite sides of the receiving box 32. The accommodating box 32 includes a box 321 disposed on the platform 31 and having opposite openings 322, and two covers 323 that respectively open and close the opening 322. The axle post 33 can be used to tie the wire, avoiding the plug falling off and the wire being too messy in use, and the design of the platform 31 can be easily moved to a desired position.

Referring to FIG. 3, and referring back to FIG. 1 and FIG. 2, the power supply unit 4 includes a power input mechanism 41 located in the receiving box 32 of the carrying unit 3, and a power input mechanism 41 located in the receiving box 32. a first power supply mechanism 42 for outputting a first power source, a second power supply mechanism 43 located in the accommodating box 32 and electrically connected to the power input mechanism 41 for outputting a second power source, and a grounding mechanism for grounding Grounding mechanism 44. The first power supply mechanism 42 and the second power supply mechanism 43 are located on opposite sides of the receiving box 32 and face the opening 322 respectively. The grounding mechanism 44 is a 120A copper grounding clamp for improved safety.

The power input mechanism 41 has an isolation transformer 411 and two warning lamps 415 electrically connected to the isolation transformer 411 and exposed to the cover 323. When the isolation transformer 411 is electrically connected to an external power source, the warning light 415 will illuminate to alert the operator. The isolation transformer 411 has a power input terminal 412 for connecting an external power source, a first output terminal 413, and a second output terminal 414. In this implementation In the example, the isolation transformer 411 is a 12KVA isolation transformer. The power input terminal 412 can input a power supply of 460V. The first output terminal 413 is a first power source for outputting 110V, and the second output terminal 414 is used for A second power supply of 24V is output.

The first power supply mechanism 42 has a plurality of first sockets 421 and a first leakage circuit breaker 422 electrically connected to the first socket 421 and the first output end 413 of the power input mechanism 41. The second power supply mechanism 43 There is a plurality of second sockets 431, and a second earth leakage breaker 432 electrically connected to the second socket 431 and the second output end 414 of the power input mechanism 41. The first socket 421 can provide a first power source of 110V, and the second socket 431 can provide a second power source of 24V. The first earth leakage circuit breaker 422 and the second earth leakage circuit breaker 432 can improve overall safety.
