The pulse DC source comprises a PLC system; the PLC system comprises a programmable controller, a peripheral circuit and an input power supply for supplying power for the programmable controller; the peripheral circuit comprises a multipath adjustable DC circuit; the multipath adjustable DC circuit comprises a switch contact, a DC source and a solenoid valve which are controlled by the programmable controller; and the switch contact, the DC source and the solenoid valve are in series connection. According to the pulse DC source, the DC source in the multipath adjustable DC circuit is employed as the constant voltage source for the solenoid valve, the turn-on and break states of the switch contact is controlled by the programmable controller by programming, further the open and conduction states of the adjustable DC circuit are controlled, and a pulse direct current is output.
Description
Technical field
The utility model relates to power supply, is specifically related to the pulse power.
Background technology
When doing the electromagnetically operated valve durable test, need driving source and environmental cabinet, vibration machine to be combined together, but also be not exclusively used in the driving source of electromagnetically operated valve durable test at present.When doing the electromagnetically operated valve durable test, there are problems such as volume is big, complex structure, cost height as driving source in the general pulse powers that adopt but have the pulse power now more more.
The utility model content
The purpose of this utility model is, a kind of pulse dc power is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of pulse dc power comprises 1 PLC system, described PLC system comprises 1 Programmable Logic Controller, peripheral circuit, also comprises that 1 is the input power supply of Programmable Logic Controller power supply, it is characterized in that, described peripheral circuit comprises 1 adjustable DC loop of multichannel, the adjustable DC loop of described multichannel comprises switch contact, DC power supply, the electromagnetically operated valve that is subjected to described Controlled by Programmable Controller, described switch contact, described DC power supply, the series connection of described electromagnetically operated valve.
The utility model utilizes Programmable Logic Controller to export pulse direct current by the state that switches on and off of programming Control switch contact the constant pressure source of the DC power supply in the adjustable DC loop of multichannel as electromagnetically operated valve.
Described DC power supply has a plurality of, a plurality of DC power supply parallel connections, and the adjustable DC loop of described multichannel also is provided with a contactor, and a plurality of DC power supply connect described Programmable Logic Controller by described contactor.Contactor can be connected different voltage circuits as required, changes the driving voltage peak value.
Described electromagnetically operated valve is vehicle-mounted electromagnetically operated valve preferably.And because the high reliability of PLC is fit to cooperate the durable test of making electromagnetically operated valve together as the driving source in the electromagnetically operated valve durable test and environmental cabinet, vibration machine very much.Also can adjust the crest voltage of power supply output by different periods and mode, and can conveniently expand according to customer requirement.
Specifically can be to comprise at least two described vehicle-mounted electromagnetically operated valves, described Controlled by Programmable Controller connects at least two described switch contacts, and at least two described vehicle-mounted electromagnetically operated valves are connected with at least two described switch contacts respectively.So that simultaneously a plurality of vehicle-mounted electromagnetically operated valves are tested.
The output voltage of described pulse dc power is 0V-30V, and output current is every contact 1A, the pulse of the needed different frequency of output able to programme, and exportable irregular pulse dashes.
Description of drawings
Fig. 1 is a kind of circuit structure block diagram of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
A kind of pulse dc power mainly comprises 1 PLC system.
With reference to Fig. 1, the PLC system comprises Programmable Logic Controller, peripheral circuit, power supply, and power supply is used for being the Programmable Logic Controller power supply, can adopts AC power or DC power supply as the input power supply for the Programmable Logic Controller power supply.
Peripheral circuit comprises 1 adjustable DC loop of multichannel, comprises the switch contact, DC power supply, the electromagnetically operated valve that are subjected to Controlled by Programmable Controller, switch contact, DC power supply, electromagnetically operated valve series connection.The utility model utilizes Programmable Logic Controller to export pulse direct current by the state that switches on and off of programming Control switch contact the constant pressure source of the DC power supply in the adjustable DC loop of multichannel as electromagnetically operated valve.
DC power supply has a plurality of, a plurality of DC power supply parallel connections, and the adjustable DC loop of multichannel also is provided with a contactor, and a plurality of DC power supply connect Programmable Logic Controller by contactor.Contactor can be connected different voltage circuits as required, changes the driving voltage peak value.
Because the high reliability of PLC, the driving source and environmental cabinet, the vibration machine that are fit to very much be used as in the electromagnetically operated valve durable test cooperate the durable test of making electromagnetically operated valve together.So electromagnetically operated valve is vehicle-mounted electromagnetically operated valve preferably.But also can adjust the crest voltage of power supply output by different periods and mode, and can conveniently expand according to customer requirement.
Specifically can be to comprise at least two vehicle-mounted electromagnetically operated valves, Controlled by Programmable Controller connects at least two described switch contacts, and at least two vehicle-mounted electromagnetically operated valves are connected with at least two switch contacts respectively.So that simultaneously a plurality of vehicle-mounted electromagnetically operated valves are tested.
The output voltage of pulse dc power is 0V-30V, and output current is every contact 1A, the pulse of the needed different frequency of output able to programme, and exportable irregular pulse dashes.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
