Profile:
8000A Automatic Three Phase Long-term Running Primary Current Injection Test System With Temperature Rise is a necessary equipment for electrical debugging in various industries that require high current locations. It is applied in power plants, substations, electrical manufacturing plants, scientific research, laboratories and other units, and belongs to the short-term or intermittent working system.
It is suitable for temperature rise testing of 9000kVA transformers and 8000A switchgear (other specifications can be customized), and can operate continuously for 24 hours. Intelligent control, complete protection, stable performance, and convenient use and maintenance.
The structure of this product is a split structure, consisting of five parts: an intelligent control console, an electric induction voltage regulator, a compensating capacitor, a three-phase step-up transformer, and a three-phase step-up transformer. Lead the test sample from the output terminal block of the step-up/step-up transformer, and collect the voltage and current values of the test sample to the intelligent control panel through the voltage/current transformers on the step-up/step-up transformer. Measure, monitor, and save test current and voltage values through the LCD display screen on the intelligent console

Features:
1. Electric induction voltage regulator
Contactless magnetic induction isolation voltage regulating transformer, worm gear stepper motor mechanical transmission to regulate voltage output, adjustable thickness and precise output.
2. Three phase up current transformer
The boosting transformer adopts a fully insulated structure, T3 copper wire, and cold-rolled silicon steel plate. The transformer adopts dual coil, low-voltage input coil and high-voltage output coil. Place static shielding between low voltage and high voltage, low voltage and iron core. Magnetic coupling between high and low windings, without electrical connection.
3. Intelligent electric control console
Control the LCD screen sampling industrial computer. The sampling signal board is a passive signal converter with multi-level isolation and shielding protection, completely eliminating the destructive impact of high-voltage breakdown direction voltage and direction current on the control power supply. The controller parameters are set for the same batch after a power outage without the need to be reset and permanently saved. The test data is permanently saved 500 times for easy reference and printing.
Intelligent Electric Console - Control System
4.15.6 inch LCD touch screen display, human-machine interface, Mitsubishi PLC control, capable of printing test data.
5. High precision sensor, Mitsubishi high-performance AD analog module, with a resolution of up to 32000.
6. Choose between automatic and manual current rise tests, with flexible and simple operation.
7. Real time display of power supply voltage, power supply current, voltage regulator output voltage, output current, voltage and current of the tested object, test time display function, test results, and intuitive display.
8. Comprehensive overcurrent protection, with arbitrary setting of target output current value, current upper limit, and withstand time.
10. It has a zero return detection function and can only be tested after the zero return is confirmed, ensuring safety and reliability.
11. When the set target output current is reached, the current can be automatically adjusted to ensure that the test current is within the required range. After the timing is completed, the voltage regulator motor will automatically return to zero and the compensation capacitor contactor will be completely disconnected.
