Microcomputer control of voltage breakdown testing instrument DDJ-150KV (150000 volts) To meet the standard: Test methods for electrical strength of insulatingmaterial GB1408-2006 GB/T1695-2005 vulcanized rubber power frequency voltage breakdown strength and voltage withstand strength test GB/T3333 cable paper power frequency voltage breakdown test method HG/T 3330 insulating paint breakdown strength determination GB12656 capacitor paper power frequency voltage breakdown test method Test method for materials at commercial power frequencies the dielectric breakdown voltage and dielectric strength of ASTM D149 solid electricalinsulation. One, the scope and function Mainly applicable to solid insulation materials (such as: plastic, rubber,lamination material, film, resin, mica, ceramic, glass, insulating paint and other insulation materials and parts) in the frequency of the voltage or DC voltage breakdown strength and voltage withstand test. The instrument is controlled by computer, is my company developed a new second generation dielectric breakdown testing instrument, the instrumentis controlled by the electronic control system of Siemens PLC, data acquisition through a photoelectric isolation, effectively solve the problem of interference in the process of software test, convenient operation and use, to show the real-time dynamic curve, at the same time, the rate of pressure rise stepless adjustable, can according to their own needs toboost rate adjustment, adjustment in the range of 10V-5000V/S, in the domestic leading position (the only domestic manufacturers can achieve this function), so that the pressure rate truly uniform, accurate, and can accuray measure the leakage current data. May the real-time renderingcurves, test data show that, to judge accuray, and can save, print the test data analysis. The system can automatically determine the sample breakdown andbreakdown voltage and leakage current data acquisition, and can rapidly reduce the auto zero in instantaneous voltage breakdown. The softwaresystem is easy to operate, stable performance, safe and reliable. Two, the software function: 01, the software platform: WINDOWS windows operating platform, intuitive interface, easy operation 02, curve display: during the experiment can dynamically display the test curve 03, export data: the results of test can be imported into EXCEL table 04, the experiment report: can be artificially set report name, and print thetest report 05, test mode: can flexibly select the DC test and AC test according to the demand of 06, test method: you can choose the breakdown voltage, voltage withstand test, gradient test according to the demand of 07, setting of parameters: according to the different parameters in different ways and test methods flexibly set the required value 08, sample setting: can the sample parameters of different standard flexiblesettings 09, personnel management: set the user name and password, different operators in different test, do not influence each other 10, the standard choice: containing different standard, according to theirneeds 11, continuous operation: continuous operation test, can directly start testin the software, test two times Three, the technical requirements: 01, the input voltage: 380 V 02, the output voltage: AC 0--150 KV; 03, electrical capacity: 20KVA 04, high grade: 0--5KV; 0-10KV; 0--20KV; 0--50KV; 0 100KV; 0 150KV 05, the rate of pressure rise: pressurization rate: 10-5000V, (in this interval can be set manually, currently the only can achieve thefunction of the instrument) 06, test methods: DC test: 1, 2, 3 speed boost pressure gradient, pressure test AC test: 1, 2, 3 speed boost pressure gradient, pressure test 07, to stop two kinds of methods: 1, voltage, current judge sentenced 2 stop stop 08, the voltage and current acquisition mode: photoelectric isolationacquisition, effectively ensure the safety and reliability of the control system. 09, the test medium: air, oil test Over current protection device 10, the installation of high sensitivity to cut off the power supply to ensure the sample breakdown in 0.05S. 11, the use of advanced inligent integrated circuit uniform pressure. 12, support for a short time short-circuit test requirements. 13, voltage test accuracy: ≤ 1%. 14, the test voltage is continuous and adjustable: 0--100 KV. 15, the current can be collected to class mA 16, electrode size: 1, the sheet electrode - 25mm two - 75mm a sheet electrode 2, enameled wire electrode two 3, work two electrodes 17, host size: length and width and height of -2100*1650*2500 (MM) 18, operation table size: -2100*1500*1200 long width height (MM) 19, the protective cover material: white transparent organic glass 20, the oil groove dimensions: length width height -300*200*150 21, weight: about 500KG Four, security protection: The instrument has the advantages of safety protection measures areperfect: The test instrument circuit protection control: (1) the overpressure protection (2) overcurrent protection, short-circuit protection (3) (4) (5) leakage protection misoperation of protection software Five, test methods 1, insulation test samples in air 2, insulation test specimen immersed in Six, test interface: 1, test interface 2, the parameter setting interface: 3, the print preview screenshots The main configuration, equipment seven Equipment standard Name configuration note The 01 test a host 02 a set of control device 03 the test electrode two (three) The 04 test tank two The 05 discharge system 06 a set of control system 07 data collection system A set of 08 test software installation disk 09 a Lenovo computer The 10 one ink-jet printer Canon brand 11 using a manual 12 protective resistance a A 13 national level measurement certificate 13 product certificate
