Three-Phase Primary Injection Testing Kit

Three-Phase Primary Injection Testing Kit

In daily operations, it is necessary to verify through high-current simulation testing whether equipment such as switchgear, bus ducts, circuit breakers, isolating switches, and cable joints will overheat when energized for extended periods and whether they can withstand the rated current. Additionally, the turns ratio, polarity, and load capacity of current transformers, as well as the operating sensitivity of various overcurrent relays and protective devices, can all be tested using 3,000 A high-current testing equipment.

Products Description

 

 

primary current injection test set

The HMSLQ-3000A Three Phase High Current Generator is a high-current test system designed for AC high-current injection and long-duration temperature rise testing. It provides up to 3000A three-phase AC output, with continuous and stepless current adjustment from 0 to 3000A.

The system uses a PLC-based control system, automatic current stabilization, three-phase automatic balancing, digital measurement, and multiple protection functions. It is designed to simplify high-current testing while improving current control accuracy and test efficiency.

 

Main Keys

1. 3000A Three Phase High Current Output

The HMSLQ-3000A provides a maximum AC output current of 3000A for three phases, with a 7V line voltage. The output current can be continuously adjusted from AC 0–3000A using a stepless adjustment method.

The system supports:

Three-phase simultaneous output

Single-phase output

Separate-phase output

Continuous current adjustment

Long-duration temperature rise testing

This configuration allows the same high-current test system to support different test requirements and connection methods.

2. PLC Automatic Control System

The system uses a programmable logic controller (PLC) as the central processor. It performs real-time scanning and monitoring of AC signals and provides closed-loop control during the test.

The operator can set the required test current and test duration through the touch-screen interface. The system then automatically controls the output current according to the preset test parameters.

3. Automatic Current Stabilization

During testing, the HMSLQ-3000A automatically tracks the target current and stabilizes the output current.

The system can automatically adjust the three-phase current and return the regulator to the zero position after the test is completed. This reduces the need for continuous manual adjustment during long-duration tests.

4. Three-Phase Automatic Balancing

The HMSLQ-3000A incorporates a three-phase automatic balancing system to maintain balanced three-phase output.

High-precision current transformers are used for output current sampling. Combined with power electronic technology, the system provides strong interference resistance and an output accuracy of up to 0.2 class.

5. 15-Inch Touchscreen Operation

The equipment uses a 15-inch true-color LCD touchscreen with a digital control and measurement interface.

The interface provides:

Current setting

Test-time setting

Voltage display

Current display

Automatic control

Test status monitoring

The control interface uses a clear menu structure, allowing operators to configure the test without additional external control equipment.

6. High-Accuracy Current and Voltage Measurement

The HMSLQ-3000A uses digital measurement instruments and a color LCD display for monitoring voltage and current.

The current display uses a 6.5-digit digital display, with a display resolution of 0.001A and a display error of ≤0.2% ±1 digit. The voltage display has a resolution of 0.1V, with a display error of ≤0.2% ±1 digit.

7. Waveform Detection

The system is equipped with a waveform detection function for analyzing power supply quality during testing.

This function provides additional information for monitoring the electrical conditions during high-current testing.

8. Multiple Protection Functions

The high-current generator includes:

Over-temperature protection

Over-current protection

Over-voltage protection

These protection functions are designed to improve operational safety and equipment reliability during high-current testing.

9. Designed for Long-Duration Temperature Rise Testing

The HMSLQ-3000A is specified for long-duration temperature rise testing. Its cooling system uses forced-air cooling, with an overall efficiency of ≥80%.

The operating temperature range is -10°C to 50°C, with relative humidity of 0–90% under non-condensing conditions and an applicable altitude of up to 1500m.
