Buyer Feedback - Operation site of high current generator

I. Overview

1. Purpose

   HZ5372 high-current generator (abbreviated current booster), the test equipment developed by our company, integrates the advantages of similar products at home and abroad, adopts numerical control technology, and has strong anti-interference ability. Compared with the previous generation current booster, Due to the low power consumption, large capacity self-coupling voltage regulator and the converter made of high magnetic permeability iron core, it has the advantages of large output power, small size and light weight. It is mainly used for primary busbar protection and various current transformer transformation ratio test items, and is widely used in scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgical and mining enterprises.

2. Performance characteristics

Beautiful and elegant PVC panel

The operating time of the test equipment can be synchronized

Automatic identification of normally open and normally closed contacts

Several calibrators can be connected in series at the same time to improve work efficiency

Directly display the test value of primary current and secondary current, which is convenient for test observation and recording.

High measurement accuracy 0.5 level

Large power, small size, strong load capacity

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

3. Operation

(1) After the wiring is completed, check it again to see if 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 sparking or no display when starting up, turn off the power immediately and recheck the wiring.

(3) In actual wiring, the current output terminals should form a loop, otherwise the instrument will not output current.

(4) The current booster has a random output wire; the output external copper wire is selected according to 10A/mm2. (Standard configuration is two 3-meter test lines)

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

2. Technical Features
