TS1700 Surface Insulation Resistance Measuring System for Electrical Steel
*Above picture is only for reference, subject to actual delivery
1. Summary
TS1700 is a special instrument for measuring the insulation resistance of electrical steel sheet. The instrument supports manual turning over to measure the interlayer resistance of electrical steel. The reference standard is IEC60404-11.
2. Features
1. Built-in DC stabilized power supply and precision current measurement unit, the measurement uncertainty is up to 0.1%.The voltage value can be stabilized at 500 mV during each measurement, and the loop current is measured synchronously, range: 0 ~ 1.2 A.
2. Contact execution structure: It consists of 2 auger bits, 10 metal rods with contacts, and pressure devices.Standard contact (standard recommendation): The area of a single contact is about 64.5 mm2, and the total area of 10 is 645 mm2.
Optional contact (optional): The area of a single contact is about 100 mm2, and the total area of 10 is 1000 mm2.
The drill has good sharpness and can easily pierce the surface coating of electrical steel under certain pressure.
The drill bit and the metal rod of the contact are driven by an electric cylinder and move synchronously in the vertical direction to contact the sample for testing.
During the test, the surface pressure of a single contact is about 2 N/mm2, and the pressure sensor is equipped to monitor the applied pressure in real time.
Sample tray: it can drive the sample to move back and forth to find multiple different test areas and obtain multiple sets of test data. 1 to 5 groups of test points can be set through the software.
3.System verification standard device: equipped with standard resistance circuit board for daily verification of the system.
4. Mobile test console: Set test parameters through LCD touch screen, observe test status and results, easy to use.
5. Professional testing software: In addition to setting parameters and placing samples, other testing processes can be completed automatically through the software.
6. The software can display the voltage value, current value and pressure value of the test in real time, and record each group of test data.
