Develop Multi-circuit Test-bed For Insulated Resistance And Withstanding Voltage Intelligent

All kind of aviation tie-in, electrical outlet, electrical magnet, electrical clutch and complicated cable system have been abroad applied in every work of life in civil economy. According to the standard regulation, there have some important significance in detecting and eliminating hitch the insulation and the withstanding voltage capability of product. The paper will introduce a new multi-circuit test-bed for insulated resistance and withstanding voltage intelligent. This test-bed is compound with signal channel test apparatus, high speed SCM-CPLD double control circuit, high voltage relay unit and PC. It can accomplish fifty channels insulted and withstanding voltage test.According to the request of consumer, the system adopt the SCM and CPLD to control the high voltage relay unit , and offer the basis of hardware for the high-speed automatic test and automatic search the hitch.In PC, adopt the software visual c++ to program the automatic test and automatic search the hitch. The really using result have indicate that the system attain the target, the effect is very well and attain the praise from the collaboration.Designed the data-base management system based the SQL Server 2000. It realize not only the automatic storage and inquire, but also offer the favorable patulous capability to test other product. Under the satisfy the precondition of agreement, we take factor of agility, the credibility, facility of fixing, the layout rationality of the fix and operate desk into account that will pledge the shape slinky, circumstance nattiness and satisfy the man-machine requirement. The result of testing in laboratory and locale indicate that it has theexcellence of steady capability, high test precision, high respond speed, simple and convenient operation and credible security. The system attain the anticipate purpose and pass the check and acceptive.
