General Information:
EPS-TRT 2000A Three Phase Automatic Temperature Rise Test Bench adopts imported high-permeability materials, with exquisite design, small size, strong electric power resistance, and convenient use. In power plants, substations, electrical manufacturing plants, scientific research, laboratories and other units, it belongs to the short-term or intermittent work system. It has the characteristics of small size, light weight, and good performance. It is suitable for current load test and temperature rise test of frequency 50Hz switch, current transformer and other electrical equipment. This series of products is composed of two parts: the operating table and the current riser. It has the characteristics of stepless adjustment of output current, stable current rise, large load change range, reliable operation, simple and safe operation, etc. It can also be used as a current rise or temperature rise test for industrial and mining enterprises. current source device. Equipped with a transformer, the test current value can be easily read. Ensure the measurement accuracy of the product.

Features:
-Intuitive reading: The instrument uses a digital meter and a computer to directly display the test values of current and voltage, which is convenient for test observation and recording

-Accurate measurement: It has high measurement accuracy and accurate test value

-Accurate protection function: all digital processing, the setting of overcurrent protection value and the setting of timing current are all realized by digital, which makes the protection more accurate

-Operating mode: manual and automatic

-Including the switch from the power supply to the input of the voltage regulator, and the switch from the output of the voltage regulator to the input of the booster, that is, the front stage is closed and the rear stage is closed; corresponding to the rear stage and the front stage; emergency stop; mutual blocking

-It has the function of zero position locking of voltage regulator

-The transformer is provided with secondary open circuit overvoltage protection, which can prevent the signal line from kicking off and causing the secondary open circuit of the current transformer to generate high voltage

-The main body of the current riser is the central opening, and the large current output can be directly pierced with various conductors, which is convenient for any experiment and current generation products

-The special structure can effectively control the eddy current heating problem of the riser body bracket and the shell metal

-The upper surface of the riser body shell is provided with 4 lifting rings for easy lifting, and the bottom is provided with wheels for easy movement

-With power-off protection function, during the up-current test, if the power is suddenly lost, after the power is restored again (after the manual closing air switch on the control cabinet panel is closed), the voltage regulator motor will automatically reset to zero (with There is a zero position indication), and then the pre-stage closing, rear-stage closing, up-current, and down-current operations can be performed, and the upper power supply can be strictly avoided with impact load
