Due to the adoption of the technical scheme, the simulation direct current high voltage tester can completely fulfill the aim of experimental teaching, and students can know a direct current high voltage generator well on the premise that a school is not required to spend a large amount of money.
Description
Technical field
The present invention relates to a kind of dc high voltage tester, particularly a kind of emulation dc high voltage tester; The electric power specialty that is applicable to institution of higher learning is imparted knowledge to students.
Background technology
Power test will relate to tens of kinds of testing equipments, these equipment are mostly very expensive, if buying one by one, then to spend a large amount of funds, this there is no need fully, therefore, just need a kind of under the prerequisite that need not spend substantial contribution and can well realize the product of school's test teaching purpose.Make a general survey of the purpose of test teaching, a product architecture clearly also just arranged:
1, the emulation dc high voltage tester will keep the mode of operation that prototype is a high voltage direct current generator as far as possible, and the communication interface mode of connection of IO interface is also unified similar to prototype as far as possible with the function of each button and each terminal.Present electronic product is mostly realized man-machine interaction, the man-machine communication of hommization by liquid crystal display, so the emulation dc high voltage tester will keep the liquid crystal display interface identical with prototype.
2, owing to will reduce cost, the l-G simulation test device just can not equally have test function to test specimen with prototype, so just can't obtain data by the test to test specimen.But in order to reach due teaching purpose, the l-G simulation test device should be able to obtain and by the various qualified and underproof data of liquid crystal display by the RS232 interface.
Because all do not have product of the same type to occur at home and abroad, the emulation lightning stroke counter of my company just can satisfy this kind demand.So using, the proposition of this simulation concept and Products Development all belong to domestic initiation.
I take charge of the emulation lightning stroke counter product applications of exploitation and the function that will realize: this artificial product aims at the test Instructional Development of China Higher universities and colleges electric power relevant speciality; The purpose of test teaching is to improve student's operating ability, set up bookish knowwhy and reality high-potting between get in touch, expand student's the visual field, strengthen the competitive power after the student enters society, make them after entering into related work, enter into work fast.
Summary of the invention
At the technical matters of above-mentioned existence, the purpose of this invention is to provide a kind of simple in structure, low cost of manufacture, can satisfy the emulation dc high voltage tester of test teaching purpose.
Realize that technical scheme of the present invention is: a kind of emulation dc high voltage tester comprises emulation DC high potential test case, host computer and the connecting box that connects chamber and host computer.
Preferably, the RS232 interface is arranged on the panel of described chamber, can link together by connecting line and connecting box; One of being connected with chamber of connecting line is the RS232 interface, and an end that is connected with connecting box is the RJ45 interface.
Preferably, 16 RJ45 interfaces are arranged on the described connecting box, can link to each other with 16 identical or different chambers simultaneously.
Preferably, connecting box can be communicated with host computer by connecting line; Connecting box can be realized the conversion of signal between RS232 and the RS485, and the RS485 signal that the RS232 conversion of signals that host computer is exported becomes chamber to receive is issued chamber, also the RS485 conversion of signals of chamber can be become the RS232 signal issue host computer.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Because the employing of technique scheme, this emulation dc high voltage tester can satisfy the purpose of experimental teaching fully, allows school under need not the prerequisite of overspending, allow students very fast know well high voltage direct current generator.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1: be the theory diagram of a kind of high pressure output-controlling device of the present invention.
Embodiment:
Of the present invention a kind of emulation dc high voltage tester as shown in Figure 1 comprises emulation DC high potential test case, host computer and the connecting box that connects chamber and host computer; The RS232 interface is arranged on the panel of described chamber, can link together by connecting line and connecting box; One of being connected with chamber of connecting line is the RS232 interface, and an end that is connected with connecting box is the RJ45 interface; 16 RJ45 interfaces are arranged on the described connecting box, can link to each other with 16 identical or different chambers simultaneously; Connecting box can be communicated with host computer by connecting line; Connecting box can be realized the conversion of signal between RS232 and the RS485, and the RS485 signal that the RS232 conversion of signals that host computer is exported becomes chamber to receive is issued chamber, also the RS485 conversion of signals of chamber can be become the RS232 signal issue host computer.
The using method of described emulation dc high voltage tester:
1, MOA automatic test pattern
After the start, enter master menu, the turn control lever makes cursor pointing " MOA tests oneself " option, clicks control lever, enters the automatic mode parameter interface is set, according to concrete testing requirements parameters is set after, can enter the interface of boosting.At this moment, press the logical button of high pressure after, system will begin to boost automatically, at this moment, can send data to chamber by host computer, after chamber receives data, as experimental record.After system rose to the test current setting value automatically, current stabilization also picked up counting, and system was depressurized to original 0.75 times automatically after timing finished, voltage stabilizing and picking up counting again, timing finish the back system automatically step-down return zero, slide out test recorded and stored dialog box, after making one's options, this time test finishes.
2, test finishes the powered-down switch.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Because the employing of technique scheme, this emulation dc high voltage tester can satisfy the purpose of experimental teaching fully, allows school under need not the prerequisite of overspending, allow students very fast know well high voltage direct current generator.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the present invention, all drop within the rights protection scope of the present invention.
