I. Overview
1. Purpose
HZ5374 primary current injection tester, referred to as (upper) is a test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-interference ability. Compared with the previous generation up , 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 generous PVC panel
Directly display the test value of primary current and secondary current, which is convenient for test observation and recording.
Secondary measurement of the transformer, transformation ratio, and polarity are displayed at the same time
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.
II. Technical Features
1. Name and classification
(1) Name: HZ5374 primary current injection tester.
(2) Environmental group: it belongs to the group III instrument (it can be used in outdoor environment) in GB6287.1-86 "General Program for Environmental Test of Electronic Measuring Instruments".
(3) Input voltage: AC380V ±10%,three phase.
(4) Power: 20KVA
(5) AC 0~4000A stepless adjustable, panel with digital display ammeter
(6) Output voltage: 15V
(7) Output waveform: The output current is a standard sine wave with tiny burrs, which is better than the power system requirements, and the ripple coefficient is less than 0.3%. Standard sine wave.
(8) Measurement accuracy: (using 0.2S grade material) is actually about 0.3; each current can be adjusted smoothly and continuously, and the accuracy is higher than 0.2 grade. The current and voltage meter shows true and effective values, with high precision and high stability.
(9) Output current mode: true effective value is continuously adjustable;
(10) Current stability: 0.2%
(11) Structural form: split
(12) Wiring method: according to requirements
(13) Protection settings: over current, over voltage;
2. 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.
(5) The capacity of the equipment is designed according to 1 hour of work.
