| Purpose & brief description |
| ● Impulse current generator is mainly used to test the ability of electrical equipment to withstand impulse current stability. It is widely used in impulse current test of zinc oxide arrester valve plate, meteorological lightning protection, and other research tests. ● Impulse current generator generates large current by parallel discharge of many capacitors. ● Application: power product manufacturing companies, power operation departments, scientific research institutions and colleges and universities. ● Application products: lightning arrester and other high voltage electrical components. |
| Test purpose |
| ● Impulse current: test the impulse current waveform and residual voltage waveform of the product. Impulse current focuses on the impact of current on the test object. ● Test for the purpose of checking the residual voltage and impulse current withstand capacity of lightning arrester, or checking the electrical performance of other electrical equipment, devices and materials under impulse current, and measuring impulse grounding resistance. |
| Technical parameter |
| ● Working power supply; 220V/380V,50/60Hz ● The impulse current generator can generate 1 / 20us, 4 / 10us, 8 / 20us, 10 / 350us, 10 / 1000US, 18 / 40us and 30 / 80us standard impulse current waveforms, mainly 8 / 20us. ● Operation time: output rated current, test once every 40s, continuous operation; ● If the output current is less than 80% of the rated current, the test shall be conducted once every 25s, and it can operate continuously; ● High precision and high sampling rate: the sampling rate is 250ms / S (the lightning impulse voltage sampling rate specified in IEC standard / GB / T 16896.1 is at least 60ms / s) |
| Technical features |
| ● Small volume, compact structure and convenient wave modulation; ● High output current (4 / 10) μ S waveform can reach 200kA); ● The device adopts the push trigger mode of lower ball cylinder, with good synchronization performance and reliable action; ● Each main capacitor bushing is connected in series with a high-energy non inductive energy absorption resistor to ensure the safety of the main capacitor; ● Constant current charging computer measurement and control integrated system is adopted, with high degree of automation and strong anti-interference ability. ● Optical fiber communication between the measurement and control console and the electrical control cabinet, and complete photoelectric isolation between operators and high-voltage electrical equipment ● Primary or secondary electrical components are not installed in the console, and electrical control executive components are installed in the electrical control cabinet ● Safety guarantee in accordance with CE standard: safety interlock, emergency stop switch, zero value boost ● Clear large icons and soft keyboard make it easy for the operator to access and set all functions and parameters ● Easy and safe to use, greatly reducing the user's learning time and minimizing the risk of misoperation ● Measurement software: automatically read data, automatically generate waveform, modify product information, calculate waveform parameters, and directly display all waveform characteristic parameters (T1, T2, in, etc.) on the waveform ● Parameters for selective display can be set, current coil multiple and voltage divider ratio can be set, and parameters can be displayed directly without secondary conversion by the operator ● Test data and waveform are automatically saved for easy export ● For arrester products: Launch multi waveform arrester lightning test equipment, which can produce a variety of waveforms: steep wave 1 / < 10 μ s. Impulse high current 4 / 10 μ s. Lightning current 8 / 20 μ s. Operating impulse current 30 / 80 μ s. Square wave current 2ms, lightning current 10 / 350 μ S and other waveforms can also produce special waveform impulse current according to customer needs. Lightning arrester lightning test equipment can cooperate with AC power supply and DC power supply to carry out various action load tests or joint waveform tests. |
