Abstract
The utility model relates to a power supply device, which comprises at least one power supply for supplying power, alternating current and direct current converters which are respectively connected each power supply and used for converting input alternating current power into direct current power, at least one power node, and an output device connected with every power node. Each alternating current and direct current converter is connected to a conversion device and used for realizing input conversion of the power supplies so as to supplying power to the at least one power node, the at least one power node is used for receiving and storing power of the conversion device, and the output device at least outputs two power sources. The power supply device has simple, strict and novel structure, and adopts a multi-power mode and a mode of multiple power nodes, thereby greatly reducing accident rate and increasing safety factor of the whole power supply device.
Description
Technical field
The utility model belongs to electronic applications, is the supply unit of using in a kind of electronic applications specifically.
Background technology
At electronic applications in the past, particularly relate to electric power scheduling automatization system, its front subsystem is being born communicating with factory station terminal equipment of task, and the needed working power of preposition communication equipment is the single supply pattern, and this becomes the bottleneck of system safety, once supply module breaks down, just cause data link to disconnect, can't normally receive and send data, thereby lose monitoring capacity, influence the safety of whole electrical network electrical network.
The utility model content
Consider above-mentioned problem, this use is novel to provide a kind of novel supply unit, by standbyly each other respectively organizing the power supply input, farthest avoiding the generation of the situation of electric power disconnection.
The supply unit that the utility model provides comprises
At least one road power supply is used for power supply;
Be connected with an AC/DC conversion equipment with each road power supply, be used for the AC power of input is converted to DC power supply;
Above-mentioned each road AC/DC conversion equipment all is connected to a switching device, is used to realize the conversion of each road power supply input, powers to power supply node;
At least one power supply node is used to receive the power supply of switching device, and stores; And
With the output device that each power supply node is connected, output device is exported the two-way power supply at least.
Above-mentioned power supply way is The more the better, can guarantee the fail safe of power supply more, and the outage coefficient is more little, but cost also increases thereupon.Preferably, above-mentioned power supply is three the tunnel, and each road all is the 220V alternating current, and promptly common civil power be convenient to use, and coefficient of safety also can reach requirement.
Above-mentioned AC/DC conversion equipment is finished the conversion by AC-to DC because provide for alternating current, and the direct current that is required to be, so change, this is easy realization.
The initial condition of above-mentioned switching device is communicated with first via power supply for acquiescence, disconnects with other two-way power supplys, makes a response rapidly after first via power supply breaks down, and is transformed into the second the tunnel, once analogizes then, and this is to realize easily.
The multiple-effect fruit is good more more for above-mentioned power supply node quantity, but cost and idleness also increase thereupon.Preferably, power supply node is set to two.
Output device is used for to next equipment out-put supply, and its way is to set arbitrarily, and ordinary circumstance according to the demand of next equipment, is set to eight the road or 10 six the tunnel.
Like this, each road input power supply is standby each other, and does not disturb mutually, and wherein some goes wrong, and also can not influence the operation of whole device.
A plurality of power supply nodes also are standby each other, can avoid whole device to break down.
Output is provided with as required, can cooperate with plurality of devices.
The power device structure that the utility model provides is simple relatively, rigorous, novel, adopts many electric source modes and many power supply nodes, and the very big reduction rate of failure of degree increases the coefficient of safety of whole device; Because the input of each power supply, each power supply node are separate, can charged for replacement and maintenance, avoided power-off service, can not influence operate as normal; Easy to use, simple to operate, can satisfy the demand of distinct device.
Description of drawings
Fig. 1 is the electrical principle block diagram of the utility model embodiment.
Embodiment
Embodiment with indefiniteness further explains, illustrates the technical program below.
A kind of supply unit as shown in Figure 1, comprising:
The two-way power supply is used for power supply;
Be connected with an AC/DC conversion equipment with each road power supply, be used for the AC power of input is converted to DC power supply;
Above-mentioned each road AC/DC conversion equipment all is connected to a switching device, is used to realize the conversion of each road power supply input, powers to power supply node;
Power supply node is set to two (only showing one among Fig. 1), is used to receive the power supply of switching device, and storage; And
With the output device that above-mentioned each power supply node is connected, output device is exported eight road power supplys.
Like this, the two-way power supply is powered to this device simultaneously, and independent, standby each other mutually, through the AC/DC conversion equipment common civil power (220V interchange) is converted to available direct current.Be connected to power supply node through switching device then, the switching device acquiescence is communicated with the first via, with the second tunnel disconnection; And power supply node is two, is independent, standby each other each other, passes through the output device out-put supply again, and out-put supply is set to ten six the tunnel according to application.
Like this, whole device has improved security performance greatly, has reduced rate of failure.
