1.Usage

HZDL 130 Primary Current Injection Tester (referred to as the current booster), our company's own research and development equipment, it combines the advantages of similar products at home and abroad, using CNC technology, strong anti-interference ability, compared with the previous generation of current riser Due to the low power consumption, large capacity self-twisting voltage regulator and high magnetic permeability core made of converter, it has the advantages of large output power, small size and light weight. It is mainly used for testing of busbar protection and various current transformers. It is widely used in research, production and electrical test sites of power, railway, petrochemical, metallurgical and mining enterprises.

2.Performance characteristics

1. Voltage and current 6 and half LCD display, with higher display precision and more accurate experimental results (the only one in China)

2.128*64 dot matrix liquid crystal display, display data more intuitive, faster reading (the only one in China)

3. The instrument display lock function, especially for the transformer to read more accurately and quickly than in the experiment (the only one in China)

4. Polarity measurement, ct polarity automatic measurement, no need for separate test (the only one in China)

5. Time meter: 0.01 s-9999.999 S liquid crystal display (the only one in China)

6. Added self-locking function (the only one in China)

7. Variable ratio automatic detection function

8. Added internal stop meter function

9. Beautiful and generous PVC panel is adopted to make the panel more resistant to dirt and wear

10. High measuring accuracy, 0.5 grade

11. Large power, small volume and strong load capacity

12. Small size, light weight, the volume is only 30% ~ 70% of similar products, very convenient to carry.

3.Operational aspects

(1)  after the completion of wiring, check whether there is any wiring error and whether the connector is in good contact.

(2) during the test, if there is any abnormal phenomenon such as lighting or no display when starting up, the power should be immediately turned off and the wiring should be rechecked.

(3) during actual wiring, the current output terminal should form a circuit, or the instrument will not output current.

(4) the current riser is equipped with random output conductor; The output external copper wire is selected according to 10A/mm2. (two 3-meter test wires are standard)

(5) the capacity of the equipment is designed for short-time work of 5 minutes. If it is used for batch test, the working time should be less than 2.5 minutes. Wait for 10 minutes before the next work. If do temperature rise (30 minutes -24 hours) should be prepared according to long-term working temperature rise.
