Primary Current Injection Test Equipment

This special DC electric and non-pole adjustable current generator is a necessary equipment for all walks of life in electrical debugging. It is mainly used for current load test and temperature rise test for bus ducts, circuit breakers, current transformers, transformers, switches, switch cabinets, cable joints, guide rails and other electrical equipment.current transformers, transformers, switches, switch cabinets, cable joints, guide rails and other electrical equipment.

It is quite popular in power plant, transformer substation, electric appliance factory, scientific research, laboratory and other units.

It is a split structure, composed of a control console, large current generator, and an electric induction voltage regulator. The large current generator is connected with tested object, to measure, monitor and operate through CT in large current generator and current meter, voltmeter, indicator and button.

Primary Current Injection Test Equipment is generally divided into the following types according to use: 　　

1.Single-phase Primary Injection Test Set 　　

2.Three-phase Primary Current Injection Test Set 　　

3. Intelligent automatic Primary Current Injection Test System　　

4.Temperature rise Primary Current Injection Test System

5.DC high current generator

1. In the process of use, according to the requirements, connect the current booster and the tested product, and then connect the power supply.

2. The operator can choose the position of the current transfer switch according to the current required by the tested product. Since the current transformer is not allowed to open, the transfer switch can be intelligently adjusted to the large or small position and cannot be adjusted to the middle position.

3. Turn on the power, the green light is on, press the pneumatic button, the green light is off and the red light is on, turn the regulator handle clockwise to adjust the current to the required value.

4. The operator speaks the regulator handle counterclockwise, adjusts it to zero, then presses the stop button, the red light is off and the green light is on, the test is over.

The above are the methods used by the high current generator. After we understａnd the use of the instrument, we need to clarify the precautions of the operation process:

1. There should be no less than two test personnel, one person performs the operation, and one person supervises the operation to ensure the safety of the process.

2. The shell of the device must be grounded, so don't ignore personal safety issues because of low voltage. The instrument must have a good grounding, and the operating table must be close to the ground when the current generating transformer is used to ensure safety.

3. The lead from the instrument to the tested product should not be too long, the cross-sectional area should be sufficient, and the contact area should be cleaned, otherwise the connector will heat up, or the current will not rise to the set value.

4. When working together normally, first check that the power supply has sufficient capacity, otherwise the power cord heating and voltage drop will affect the normal work.

In the process of operating the high-current generator for work, it is necessary for the personnel to understａnd the use method and precautions of the high-current generator, which can be more helpful to help it perform better detection and ensure the authenticity and reliability of the data.

Wuhan Goldhome Hipot Electrical Co.,ltd is one of the earliest enterprises specially in develop, design and manufacture high-voltage testing equipments in China.
