HZDL-2000III 2000A 3 Phase Primary Current Injection Test Set

I. Intruduction

1. Purpose

HZDL-2000III Primary Injection Test Set 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.

II.Tech Data

2. 1 Input voltage: AC 380 50Hz three-phase four-wire.

2. 2 power rate: 10KVA 3

2. 3 Output current: AC0-2000A steplessly adjustable, panel with digital display ammeter

2. 4 Output voltage: 5V

2. 5 Output Waveform: The output current is a standard sine wave with tiny burrs, which is better than the power system requirements and standards, and the ripple coefficient is less than 0.3 percent . Standard sine wave.

2. 6 Measurement accuracy: (using 0.2S grade material) is actually about 0.3; each current can be smoothly and continuously adjustable, and the accuracy is higher than 0.5 grade. The current and voltmeter display is a true effective value, with high accuracy and high stability.

2. 7 Output current mode: the true effective value is continuously adjustable;

2.8 Current stability: 0.2 percent

2.9 Structure: One

2.10 Wiring mode: as required

2.11 Protection settings: over-current, over-voltage

2.2 When the current is 2000A, the current injection time can reach 30 minutes

2.13 Can test the ratio and polarity of CT

2.14 The instrument has a timed emergency stop function

2.15 with wheels, movable

2.16 A B C three-phase can set different current output values for simultaneous output.

Instructions

1. Before turning on the power, turn off the "power control" switch, and adjust the "A phase adjustment", "B phase adjustment" and "C phase adjustment" counterclockwise to zero.

2. Turn on the power, connect the "power input" A, B, C, and N terminals to a three-phase four-wire power supply, and then connect the "A, B, C phase current output" terminals to the device under test with special test leads.

3. After the connection is completed, close the "Power Control" switch, press the "Start" button, and clockwise adjust the required test current for "A phase adjustment", "B phase adjustment" and "C phase adjustment"), and then press " Stop" button and press the "Start" button again to perform characteristic tests on the tested switch, circuit breaker, and bus.

4. For the operation of lack of phase and unbalanced operation of three phases, only one phase needs to be disconnected or adjusted to zero and open.

5. If there is only 220V power supply on site, you can short-circuit the ABC input to the live wire of the power supply, and connect the N of the equipment to the neutral wire; other operation methods are the same as 1, 2, 3, and 4.
