I. Overview
1. Purpose
HZDL-2000III Primary Current injection Tester is a test equipment developed by our
company. It combines the advantages of similar products at home and abroad, adopts
numerical control technology, and has strong anti-interference ability. Compared with the
current booster, due to the use of a low-power, large-capacity, self-coupling voltage
regulator and a converter made of a high-permeability iron core, it has the advantages of
large output power, small size, and light weight. Mainly used for thermal relay, motor
protector, contactor, circuit breaker, air switch, switch cabinet, circuit breaker, protection
screen verification.
2. Performance characteristics
◆
Use beautiful and generous PVC panel
◆
Display the primary current directly, which is convenient for test observation and
recording.
◆
High measurement accuracy 0.5 level
◆
High power, strong load capacity
3.Operation
(1) After the wiring is completed, check it again to see if there is a 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) During actual wiring, the current output terminal should form a loop, otherwise the
instrument will not output current.
(4) The current booster is equipped with output wires; (The standard configuration is
12pcs of 3m test cables)
(5) The capacity of the equipment is designed for short-time work of 30 minutes, wait for
20 minutes before proceeding to the next work.
