Product Description

SLQ Series Primary Current Injection Test Equipment High Current Generator

Introduction

Primary injection testing is a system that combines the current sensor, wiring and conduction paths in the circuit breaker with the test. It is composed of three parts: high current generator (transformer), voltage regulation and control. The current rise tester is used as a current source to test electrical and dynamic stability tests such as air circuit breakers, thermal stability, temperature rise tests, etc.

Features
1. It has zero protection function to prevent the impact of large current from damaging the test product. It cannot be started when it is not at zero position.2. Output current mode: True effective value is continuously adjustable.3. The output current is a standard sine wave.
4. The current range can be switched to improve the display fineness and facilitate more accurate reading.
5. The power supply voltage and the output voltage of the voltage regulator can be switched to display for easy observation.
6. The equipment capacity is designed for short-term, intermittent operation of 5 minutes.7. If used for batch testing, it will be turned off for 10 minutes after 2.5 minutes of continuous operation.

Test Principle

The working principle of the current booster is based on the kickback voltage of the charge in the self-inductor coil (i.e. inductor). When the switch tube is in the on state, the power supply voltage is transmitted to the load through the inductor, and the change of the magnetic field accumulated in the inductor is very small. In this case, we will find that the output voltage is lower than the input voltage.

When the switch tube is not conducting, the kickback voltage will be generated due to the rapid increase of the change of the magnetic field in the self-inductor coil. In this way, the capacitor can store more charge, thereby raising the output voltage to a higher level than the input voltage. Therefore, in each switching cycle, the charge is transferred to the inductor by the circuit, and the coil carries current during the conduction period and is released through the reverse voltage during the non-conduction period.
