2500A High Current Generator
Main Features:
◆ High-precision sensor and high-performance 14-bit AD acquisition chip;
◆ The same output value can adjust the power level according to the size and distance of the test object; increasing the test range and the safety distance from the test object.
◆ For equipment with high current value and high output power, a split design is adopted; convenient for single-person carrying and operation.
◆ Optional automatic current rise test, manual current rise test, and impact quick-break test, with flexible and simple operation;
◆ Real-time display of output current, time results, with intuitive and clear display;
◆ Perfect overcurrent protection, with arbitrary setting of target output current value, current upper limit, and current withstand time;
◆ Equipped with ground detection function and zero-return detection function; the test can only be carried out after grounding and zero-return are confirmed, ensuring safety and reliability;
◆ After power failure, it can continue output without resetting to zero and adjusting again;
◆ Approach-type current rise algorithm, automatically timing the current withstand after reaching the set target output current, and the motor automatically returns to zero after timing ends;
◆ If the set output current upper limit is exceeded, the motor automatically returns to zero and an audible and visual alarm is issued;
◆ Combining hardware and software anti-interference technologies, with stable performance, strong anti-interference capability, and adaptability to harsh electromagnetic environments;
◆ Automatic error diagnosis, making it easy to find and solve problems;
◆ Optional remote communication, door interlock alarm light and bell, open-circuit voltage calibration interface, etc.;
◆ The product is small in size, light in weight, reasonable in structure, reliable and durable.
◆ Directly measure CT transformation ratio and polarity.
◆ Fixed value output can measure switch operation time.
◆ Multiple range selection and flexible application suitable for various test devices.
2500A High Current Generator Precautions
The single machine is heavy; when moving for testing: pay attention to personal safety. The test work must be carried out by no less than two people, one operating and one supervising to ensure safety. Test personnel should maintain a corresponding safety distance from the test object. Test personnel should wear protective equipment and set up a warning area.
When used in low temperature, high altitude, high temperature, and high humidity environments; please read the product manual in detail; prevent equipment damage.
The shell must be grounded, and do not ignore personal safety accidents due to low voltage. The instrument must be well grounded, and during use, the current rise transformer and the operation console must be reliably grounded to ensure safety.
The wire from the secondary side of the current rise device to the test object should not be too long, and the cross-section should be sufficient (current density can be considered at 6-8A/mm), and the contact surface should be cleaned (can be polished with fine gauze), otherwise the joint will heat up, and even the current cannot rise to the rated value.
Before work, check that the power supply has sufficient capacity, otherwise the power cord will heat up and the voltage drop will affect normal operation.
There should be no flammable materials at the work site. For temperature rise tests, sufficient fire extinguishing equipment should be prepared.
For continuous (temperature rise) tests, someone should be on duty at the site. And regularly check the heating of the current rise source equipment, wires, and joints, and make records. Due to fluctuations in the grid voltage, pay attention to adjusting the TD to maintain the rated test current. During the test, once any abnormal phenomenon is found, immediately cut off the air switch power supply, find out the cause, and then conduct the test again. After the test, the voltage regulator must be returned to zero, cut off the power supply by the air switch, cut off the working power, and then remove the test wiring in the reverse direction to ensure safety.
The test work should comply with the relevant provisions of the electric power safety work regulations and formulate practical safety measures.
