The working principle and usage method of a high current generator

A high current generator is a testing equipment for electrical debugging in various industries that requires high current locations. It can be used in power plants, substations, electrical equipment manufacturers, scientific research, laboratories, and other units. The equipment has the characteristics of small size, light weight, good performance, and convenient use and maintenance. The working principle is that after connecting to the working power supply, the high current required for the test can be obtained by adjusting the output voltage of the voltage regulator. The high current output for the test can be manually or automatically adjusted.

The performance characteristics of a high current generator: stable output current, clear instrument indications, easy to record data and observe the measured object. The output current is divided into different levels, and the size of each level is smooth and adjustable. The lifting control is free, and the adjustment is continuous and uniform. Small size, light weight, flexible movement, and convenient operation, suitable for outdoor use. The high current generator is a recognized instrument for current and load testing of this type of electrical equipment, widely used in power plants, substations, electrical equipment manufacturers, research laboratories, and other units.

Inspection before testing the high current generator and handling of common problems during testing:

1. Connect the working circuit according to the electrical schematic diagram, and the transformer casing and operating platform must be well grounded.

2. After turning on the power, the green indicator light on the high current generator console will light up. Press the start button and the red indicator light will light up. At this point, the current riser will wait for the current to rise.

3. Rotate the voltage regulator evenly in a clockwise direction, paying attention to the output current indication on the operating platform until the required high current is reached. To ensure testing accuracy, a standard ammeter can be connected in series to the instrument terminals.

4. During the high current generator test, if any abnormal phenomena are found, the power should be immediately cut off, and the cause should be identified before conducting the test.

5. After the test is completed, the voltage regulator must return to zero, press the stop button to cut off the power supply, cut off the working power supply, and then remove the test wiring to ensure safety.

6. High current generators are designed for short-term operation and are not allowed to operate at rated capacity for extended periods of time, especially when operating above rated current to prevent overheating.

7. When using a high current generator, the current transformer and operating platform must be reliably grounded to ensure the safety of the test.

The ZC-510 series high current generator is a specialized equipment designed and manufactured for electrical equipment testing in the power sector and industrial and mining enterprises. It is suitable for current load testing and temperature rise testing of various switches, current transformers, and other electrical equipment. The KST-510 series high current generator is a current source used for inspection, which is a low-voltage high current power supply for thermal and dynamic stability tests of electrical appliances, such as temperature rise tests and tripping of air circuit breakers, contactors, and relays. When measuring three phases using a single-phase high current generator, it should be carried out separately; The three-phase high current generator is mainly used for testing three-phase electrical products, and can also be used for testing single-phase electrical products. The control scheme for three-phase and single-phase high current generators is the same, except that the three-phase high current generator outputs three-phase current. The high current generator consists of three parts: a transformer, a voltage regulator, and a control.
