Product Desciption
1. Product Introduction
NRXZ Series Variable Frequency Resonant AC Hipot Tester is mainly designed for AC withstand voltage test of primary electrical equipment in substation, such as transformer, GIS system, SF6 switch, cable, bushing and other capacitive equipment. The reactor uses separate design, not only can meet the requirements of high voltage and low current devices, but also meet the test requirements of low voltage and high current devices, with a wide scope, it is an idea withstand voltage equipment for high voltage test department and electrical installation, maintenance engineering units.
2. Technical parameters
3.1 Operating condition
(1) Temperature: -10ºC ~ 50ºC
(2) Relative humidity: ≤ 90%RH;
(3) Altitude: ≤ 1000m
3.2 Inverter power supply (1 piece)
(1) Rated power: 5-500kW;
(2) Input voltage: Three-phase 380V±5% or single-phase 220V±5% 45~65Hz. When the power supply is 380V, rated load test can be done; when the power supply is 220V, only 1/2 load test can be done.
(3) Output voltage: 0~400V adjustable
(4) Output voltage frequency: 20~300Hz
(5) Frequency adjustment: 0.1Hz step adjustable
(6) Frequency instability: ≤ 0.02%
(7) Output current: 13~1250A
3.3 High voltage reactor (several pieces)
(1) Rated working voltage: 0~1000kV
(2) Rated working current: 1~10A
(3) Rated inductance: 30~600H
(4) Continuous working time: 15min
(5) Temperature rise: less than 60ºC
(6) Working frequency: 20~300Hz
3.4 Excitation Transformer
(1) Rated capacity: 3.5~500kVA
(2) Input voltage: when the capacity is 5.5~20kW, the input voltage is 200V/400V
When the capacity is 20~500kW, the input voltage is 400V
3.4. Capacitor voltage divider (one set):
(1) Capacitance: 300~5000pF
(2) Rated voltage: 10~1000kV
(3) Working frequency: 20~300Hz
(4) Accuracy: 1.0%
3. Product characteristics
1) The instrument has the functions of over-voltage, over-current, zero-position start-up, system detuning (flash-over), sectional voltage output, each sectional voltage can be preset test time independently.
2) The instrument adopts 7-inch or 10-inch touchable LCD screen, the contactor and circuit breaker of Schneider or ABB.
3) The test data can be real time printed and stored.
4) Its output circuit is equipped with special contactor, which can eliminate potential danger ultimately when touch the output line after shutdown.
5) Inputting wide range of voltage and frequency, 50Hz-60Hz frequency self-adaptive, allow our instrument to work reliably both on generator and industrial power supply.
6) Here are four operating modes for the instrument with wide frequency modulation output(20~350Hz), which is not only money saved and also reliable for use, easy to carry. The working modes are: fully automatic mode, manual mode, automatic frequency searching mode and online mode.
7) Multiple inverter power supplies can be parallel output, which allowing different time purchased inverter power supplies paralleled as a big power single power supply to use. There's no need to purchase extra-large power inverter power supply. This function was pioneered by our company, which is money saved for customer.
