Intelligent test bench for AC withstand voltage test

 Power Frequency Voltage Withstand Test Intelligent Operation System A combination of IPC with PLC, FKGB intelligent system is an integration of control, operation, inspection and protection, which monitor test parameter of test object simultaneously with working condition of system. If some potential problem emerge, the system can judge it and carry out protection, thus enhancing test security. Rather than through the original cable, system signal is transmitted through optical fiber, making it possible electrical isolation between main system and control part, especially upper machine and operating personal. Therefore, test system and operating staffs are completely guaranteed against danger.

Key FeaturesProgrammable voltage step-up function by user: parameters programmable are test voltage per segment, voltage step-up speed and withstand timeReal-time recording and saving function of test data and curve during test: record curves of u-t and u/t-tInstantaneous memory function of data and curve during test object breaking downStrong protection function of fiber optical isolation for operating staff and test system.Range of applicationVarious kinds of power frequency HV test transformer systemStructureDesk and portable, with the former suitable for HV test hall and latter for field testPerfect control functionAutomatic intelligent control function: system can auto-complete test according to preset test programme, and monitor parameters at each point.Voltage tracking function during withstand: system can auto-follow up the change of test voltage during test, and adjust test voltage to preset value in real timeControl function of voltage step-up speed: voltage step-up speed can be auto-adjusted according to test programme set by user (stepless voltage adjust)Auto-hang power on compensating reactor function: system auto-calculate the so called capacity of test object, then auto-hang and power on the suitable compensating reactorManual intervention function: manual operation is possible at any time during auto-control periodReal time status self-checking and status displaying functionReal-time measurement, display and save of data in each measuring point of systemReal-time monitor and display of working condition in each system segmentOpen-type test programming functionInstantaneous data and test curve of system breaking down are recorded and savedReal time display of test u-t and curve u/t-t is possibleReliable multiple protective functionOptical fiber isolation :Communication and control between operation system and main equipment are achieved through optical fiber, making the isolation between main equipment, operating area and operating staff possible; therefore, control and measuring part and operation staff can completely avoid injury if common test transformer strike back over-voltage when flash over occurs in test object.Flashover protection :With the system, HV signal undergoes sampling process directly through hardware, once flashover signal is sampled, the system implements protection immediately.Over-voltage protection :PLC keeps sampling through A/D template U3 HV value, which is then compared with preset value (set by upper machine), and carries on protection.Protection on abnormality of HV sampling signal :System gives a key surveillance to HV signal, and implements protection immediately when HV signal appears abnormal.Protection on abnormality of communication :When system is in operation, PLC keeps a real-time monitoring on optical fiber communication at each point and carries on different protection method on the basis of signal grade.HV restriction protection :If system step up voltage to set value, further step-up operation will not work, thus eradicating over voltage caused by misoperation.Emergency braking function :Based on physiologic habit of human, the system install a safe foot emergency braking switch, which is stamped when something abnormal arises during test, and main power is turned off.Perfect report management functionDatabase inside system can save historical test data of every test object and build test report by itself, with retrieval mode flexible and simple for user to call historical data, judge the status of test object, and create files.Name of test objectModel of test object (specification)ManufacturerTest timeUser can inquire and call historical data, and print test report by various kinds of searching mode:
