Product Details

It adopts a portable ergonomic design and advanced single-chip microcomputer control technology, making the instrument simple and convenient to operate. During the entire testing process, the performance is reliable and stable, and the readings are intuitive and fast. The application of high-precision sensors effectively ensures the accuracy of test data. The whole test unit includes: high-precision millisecond meter, true RMS ammeter, current sensor (imported), voltage regulator, high-power current booster (imported materials), microcomputer controller, printing function (optional), etc.

Main Features:

This series of products adopts split or integral structure according to different volume and weight, with stepless adjustment of output current, smooth current rise, wide load change range, reliable operation, and simple operation.

Main Uses:

High Current Generator is a special equipment designed and manufactured for power departments and large industrial and mining enterprises to carry out power equipment tests. It is suitable for current load tests and temperature rise tests of various switches, circuit breakers, current transformers, and other electrical equipment.

Precautions:

1. The test work must be carried out by at least two people, one operating and one supervising to ensure safety.

2. The shell must be grounded. Do not ignore personal safety accidents due to low voltage. The instrument must have good grounding. During use, the booster transformer and the operation console must be reliably grounded to ensure safety.

3. The wire from the secondary side of the booster to the tested object should not be too long, and the cross-section should be sufficient (current density can be considered as 6-8A/mm). The contact surface should be cleaned (can be polished with fine sandpaper), otherwise the joint will heat up, and even the current cannot rise to the rated value.

4. Before work, check that the power supply has sufficient capacity, otherwise the power cord will heat up and the voltage will drop, affecting normal operation.

5. There should be no flammable materials at the work site. For temperature rise tests, sufficient fire extinguishing equipment should be prepared.

6. For continuous (temperature rise) tests, someone should be on duty at the site. Regularly check the heating condition of the current source equipment, wires, and joints, and make records. Due to the fluctuation of 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, the air switch power supply must be cut off, the working power must be cut off, and the test wiring must be removed in the reverse direction to ensure safety.
