China New Product Tvs Diode Esd Protection - Surge Protection Devices – TP20D – Ruilongyuan

1.UVT: It is an abbreviation of Ultra low voltage triggering technology. It is a design that absorb the high and low voltage energy of the surge in advance. It can absorb the surge energy more completely, and the residual voltage is low, and the protection effect on the back-end equipment is obvious. This technology is patented by Ruilongyuan.

2.Class I: In this paper, a luminaire that refers to “accessible conductive parts connected to protective earthing conductors in fixed wiring” (from IEC60598 – luminaires – general requirements and test – Chinese version).

3.Class II: In this paper, the term “light-protection protection is not only dependent on basic insulation, but also has additional safety measures, such as double insulation or reinforced insulation, but no protective grounding or protection measures depending on installation conditions” (from IEC60598-Luminaires – General Requirements and Tests – Chinese version).

4.Leakage current: In this paper, the current flowing through the SPD does not occur when the power is connected. For example, zinc oxide varistor is a device with leakage characteristics.

5.Freewheeling: Current from the connected power source that flows through the SPD during and after the discharge current passes. For example, gas discharge tubes and thyristors are devices with freewheeling characteristics (cited from IEC61643-11)

6.20kA: refers to the maximum discharge current (Imax) in the 8/20μs surge waveform test.

7.20kV: refers to the nominal discharge voltage (Vn) in the 1.2/50μs surge waveform test.

8.Rated operating voltage: The normal AC mains voltage rating assigned by the manufacturer to the SPD (cited from Ul1449).

9.Max. Continuous voltage: The maximum rms voltage that can be continuously applied to the SPD (cited from IEC61643-11).

10.Nominal discharge current: The current peak selected by the manufacturer. With SPD, the current waveform is 8/20μs, and the SPD remains functional after 15 surges (from UL1449)

11.Maximum discharge current: The peak value of the SPD current flowing through the 8/20 waveform and the manufacturer’s claimed amplitude. Belongs to the T2 test type (quoted from IEC61643-11).

12.Nominal discharge voltage: The discharge open circuit voltage peak with a 1.2/50 μs waveform and flowing through the SPD (this parameter is the RUILON laboratory custom parameter, which is equivalent to the open circuit voltage Uoc defined by the T3 test in IEC61643-11).

13.Maximum discharge voltage: The peak value of the SPD voltage flowing through the 1.2/50 waveform and the manufacturer’s claimed amplitude (this parameter is the RUILON laboratory custom parameter, which is twice the open circuit voltage of the T3 test in IEC61643-11). (2Uoc)).

14.Voltage protection level: The maximum voltage expected to occur between the two ends of the SPD due to the application of a specified gradient of the impulse voltage and the specified amplitude and the inrush current of the waveform (cited from IEC61643-11).

A variety of wiring methods are combined to meet string and parallel wiring requirements.

Since the introduction of the 20kV ultra-thin surge suppressor in 2014, Ruilongyuan Electronics has continuously improved its surge protection technology and proposed the theoretical concept of efficient absorption of surge energy. After many tests, the circuit model was established and the ultra-low voltage triggering scheme (UVT1) was introduced. It was applied to the new totem surge suppressor, which greatly improved the surge protection efficiency and played a good role in the protected equipment. Surge protection effect.

Notes:

1.The connection line of the lightning arrester will be  connected after tining.

2.If there are no wiring terminals, wires should be welded,and the welds need to do isolation treatment.

3.L—-Brown;  N—- Blue; P E—Yellow and Green.
