I.Overview
1.purpose
HZ53766000A Primary Current Injection Tester (referred to as upconverter), our own self-developed test equipment, it combines the advantages of similar products at home and abroad, using CNC technology, strong anti-interference ability, compared with the previous generation upconverter Because of the use of low-power, large-capacity self-coupling voltage regulator and high permeability iron core converter, it has the advantages of large output power, small size and light weight. Mainly used in primary bus protection and various current transformer transformation ratio test projects, it is widely used in electric power, railway, petrochemical, metallurgy and mining companies such as scientific research, production and electrical test site.
2.Performance characteristics
Aesthetic and elegant PVC panel
Directly display the test values of primary current and secondary current, which is convenient for experimental observation and recording.
Secondary measurement, turn ratio and polarity display of CT PT
High measurement accuracy:0.5 level
High power, small size, strong load capacity
Small size and light weight, the volume is only 30% to 70% of similar products, so it is very convenient to carry.
II.Technical Characteristic
1.Name and Classification
Name: HZ5376 6000A Primary Current Injection Tester.
Environmental group: It belongs to the group III instrument in GB6587.1-86 "General Survey of Environmental Measurement of Electronic Measuring Instruments" (that is, it can be used in outdoor environments).
Input voltage: AC380V ±10%
Power :36KVA
Output current: AC0~6000A stepless adjustable, panel with digital display ammeter
Output voltage:6V
Output waveform: The output current is a standard sine wave with small glitches, which
is better than the power system requirements index standard, and the ripple coefficient is less than 0.3%. Standard sine wave
Measurement accuracy: (Using 0.2S grade material) The actual is about 0.3; each current can be smoothly and continuously adjusted, the accuracy is higher than 0.5. The current and voltage meter shows true and effective value, high accuracy and high stability.
Output current mode: true effective value is continuously adjustable;
Current stability: 0.2%
Structural form: Fission
Wiring method: according to requirements
Protection settings: overcurrent and overvoltage;
2.Operating
(1) After the wiring is completed, you should 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 a fire, and there is no abnormality such as no display when starting up, immediately turn off the power 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 riser is provided with 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 one hour operation.
