Purpose of the present invention just is to overcome above-mentioned defective, the safe isolation experiment system of design, a kind of intelligent insulating tool of development.
Technical scheme of the present invention is:
Intelligent security isolation insulating tool experiment system, its major technique are characterised in that by measurement mechanism and data processing equipment to be formed, measurement mechanism by several measure passage, a controller is formed; Each is measured in the passage, and the chain type high voltage micro-current disengaging gear connects container, and container connects sample circuit, and sample circuit one tunnel connects reometer, and another road connects the multidiameter option switch in the controller; In the controller, multidiameter option switch connects the effective value modular converter, and the effective value modular converter connects A/D converter, and A/D converter connects first central processing unit, and first central processing unit connects wireless signal transmitting module, and accumulator connects each parts; In the data processing equipment, the wireless signal transmitting module coupling in wireless signal receiver module and the controller, the wireless signal receiver module connects second central processing unit, and second central processing unit connects keyboard.
Integrated use of the present invention a series of technical renovation:
1) technical requirement of two rules is weaved into software (software flow pattern is seen Fig. 3), embedded in this pilot system, make native system can gather, write down, transmit, judge, report to the police and print test findings automatically, realize intelligent, robotization;
2) designed special holding circuit at the two ends of the reometer of measurement mechanism;
3) design in each pilot passageway of measurement mechanism, the chain type high voltage micro-current disengaging gear has been installed, during not good or insulation breakdown, can have in time been cut off this pilot passageway, the safety of warranty test transformer and other test unit when the test specimen insulating property; Simultaneously, significantly reduced electromagnetic interference (EMI) to spatial emission.
4) the high-low pressure experiment power supply does not need to receive simultaneously in the measurement mechanism, has avoided a potential safety hazard.
5) test figure that collects of measurement mechanism is sent to data processing equipment by wireless mode, and testing crew away from the high-potting power supply, has guaranteed their personal safety when reading test figure.
Advantage of the present invention and effect are, by having used above-mentioned new technology, have reached:
1) electrical isolation between data processing equipment and the measurement mechanism, personal safety has obtained sufficient assurance;
2) taked four measures, made the safety of equipment obtain sufficient assurance: height piezoelectricity isolations, reometer holding circuit, chain type high voltage micro-current disengaging gear and by early warning before the puncture of software realization;
3) incorporated the requirement of two rules, the intellectuality of system, automaticity height, test is convenient
When 4) hyperchannel was tested simultaneously, independently controlling, being independent of each other of each pilot passageway improved efficient.
