Product Details

1000A High Current Generator adopts split or integrated structure according to the output current size. The product is relatively small in size and light in weight. It also features stepless adjustment of output current, balanced current rise, wide load variation range, reliable operation, simple operation, and safety. It is an ideal equipment for current rise or temperature rise tests.  

1000A High Current Generator is specially designed and manufactured for power departments and industrial and mining enterprises to conduct current load tests and temperature rise tests on various switches, current transformers, and other electrical equipment in electrical equipment testing.

Technical Parameters

Working Power Supply: 220V or 380V  ±10%    50HZ 

Output Current: 0～10000A (according to user's choice) 

Output Voltage: 5V or 10V (according to user's choice) 

Ambient Temperature: -10℃~40℃

Working Principle

The circuit is shown in the figure. AC: 220V power is input from X, -X, adjusted by TY voltage regulator, controlled by K1, and T current booster increases the current, outputting large current through ammeter A from Xl~X. When the two sets of coils are connected in parallel, it can output 1000A current with a maximum no-load voltage of 5V; when the two sets of coils are connected in series, it can output 500A current with a maximum no-load voltage of 10V.

Precautions

1. The cross-section of the input power cable of this tester should be greater than 2mm2, and the cross-section of the high current output connecting cable should be greater than 100mm2, and the length of the output connecting cable should be shortened as much as possible.    

2. As long as the output current requirement can be met, try to use parallel output.    

3. Avoid continuous output for a long time.    

4. For safety, the grounding terminal should be reliably grounded.

Usage Method

1. Connect the working circuit according to the electrical schematic diagram. The transformer shell, operation console, etc. must be well grounded. 

2. Connect the power supply, the green indicator light on the operation console lights up. Press the start button, the red indicator light lights up, and the current booster is waiting to boost the current. 

3. Rotate the voltage regulator evenly clockwise, and pay attention to the output current indication on the operation console until the required large current is reached. To ensure testing accuracy, a standard ammeter can be connected in series on the instrument terminal. 

4. During the test, once abnormal phenomena are found, the power should be cut off immediately, and the test should be carried out after finding out the cause. 

5. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power, and then cut off the working power before removing the test wiring to ensure safety.
