The characteristic parameters of ceramic gas discharge tube is? How to quickly understand? Netizen "Lavie" to tage electronic technology Xiaobian I asked this question. Then the characteristic parameters of ceramic gas discharge tube how to understand? Today Xiaobian for everyone to explain! The characteristic parameters of ceramic gas discharge tube is divided into four main points are as follows:
1, DC breakdown voltage Vsdc: on the discharge tube 100V/s DC voltage applied to the breakdown voltage value. This is the nominal voltage of the discharge tube, commonly used 90V, 150V, 230V, 350V, 470V and 600V, etc.. The scope of the error: generally 20% or more, and some for + + 15%, there are individual + + or + 5%.
2, pulse (impact) breakdown voltage Vsi: the breakdown voltage value of the 1kV/ pulse voltage applied on the discharge tube s. Because of the slow reaction speed, the pulse breakdown voltage is much higher than the DC breakdown voltage.
3, impact discharge current Idi: divided into 8/20 S wave (short wave) and 10/1000 S wave (long wave) impact discharge current of two kinds. Generally 8/20 S wave used more. The impact of discharge current is divided into single impulse discharge current (8/20 S wave 1 times) and the impact of the nominal discharge current (8/20 S wave 10 times), the latter generally is about half of the former, there are 2.5 kA, 5 kA, 10 kA, 20 kA...... Other specifications.
4, resistance to AC current Idac (frequency): ceramic gas discharge tube can withstand AC discharge current (power frequency) 1 seconds / time, 10 times the rated current discharge.
