Basic Introduction Of AC/DC Large Current Generator

       AC/DC large current generator is the necessary equipment for electrical debugging in high current places, and it is also the current source equipment for current rise or temperature rise test in industrial and mining enterprises, which is widely used. The following GDZX will introduce AC and DC large current generator in detail.

I Introduction

       The AC / DC large current generator is composed of two parts: the operating platform and the current lifter. It has the characteristics of stepless adjustment of output current, stable current rise, large load variation range, reliable operation, simple and safe operation. It is the necessary equipment for all walks of life in the electrical debugging places where large current is needed. It can be used as the current source equipment for current rise or temperature rise test in industrial and mining enterprises. If equipped with transformer, the test current value can be easily read.

II Features

1. The large current generator adopts energy-saving high permeability current lifter with light weight and strong load carrying capacity.

2. The large current generator is indicated by digital meter with true RMS value of 0.5.

3. Equipped with digital electric stopwatch, it can meet the time measurement.

4. It has the characteristics of high output power, strong overload resistance, clear reading and flexible movement.

5. It is suitable for power system technician to inspect current transformer, protection device and secondary circuit current test.

III Purpose

       Large current generator is used for electrical debugging in high current places, and can also be used as current source equipment for current rise or temperature rise test in industrial and mining enterprises.

IV Scope of application

       Large current generator is used in power plants, power transformation and distribution stations, electrical equipment manufacturers and scientific research, laboratory and other units. It belongs to short-term or intermittent working system. It has the characteristics of small size, light weight, good performance, etc. It is suitable for the current load test and temperature rise test of frequency 50 Hz switch, current transformer and other electrical equipment.

V Technical parameters

1. Input AC 50Hz, 220V.

2. Balanced output 0-AC and DC high current required by users; smooth, stable and continuous adjustable, with accuracy higher than 0.5; output current is standard sine wave.

3. Output current mode: the true RMS value is continuously adjustable.

4. Output waveform: standard sine wave.

5. Output opening voltage: ≥6V.

6. Current stability: 0.2%.

7. The current waveform distortion thd 1% design standard is far higher than the national standard < < gb14048.2-14 > >.

8. Over current and over-voltage are set for protection.

9. Insulation withstand voltage 1800 / AC 1min, insulation grade: B.

10. The current action time of the measured element can be measured. The locking action time can be recorded synchronously. Normally open and normally closed contacts can be identified automatically. Time range: 0.001s --- 9999.999s, accuracy; 0.001s (optional).

11. The advanced single chip microcomputer control technology is adopted in the design, which makes the operation of the instrument simple and convenient. In the whole test process, the performance is reliable and stable, and the reading is intuitive and fast. The application of high-precision sensor can effectively ensure the accuracy of test data. The test unit includes: high precision millisecond meter, true RMS ammeter, current sensor (imported parts), voltage regulator, high-power current booster (imported materials), microcomputer controller, printing function (optional function), etc.
