“…The temperature distribution of the central part of PE arc is obtained by measuring the half-width of Hu line spectrum. On the other hand, the temperature distribution of the surrounding part of the PE arc has been obtained as follows [13]. First, the integrated emission coefficient of vibration transition (0.0) band diameter and 10 A arc current is shown in Fig.…”

“…The experimental result has shown that the electrical field strength of the PE arc is several times as high as that of the air arc [ 1 11. To obtain the reason, temperature distribution of the outer part of the arc column has been estimated by measuring the radial distribution of spectral intensity of the C, molecule [13]. The result shows that the temperature is considerably lower than that of the air arc.…”

The radial temperature distributions in the central part of arcs burning through polyethylene (PE) tubes are estimated by measuring the half‐width of Hα line spectrum and using the electron density versus Stark half‐width and the electron density versus temperature characteristics. Estimation is carried out for various tube inner diameters (2 and 4 mm) and dc arc currents (5, 10 and 15 A). The result shows that the temperature at the arc center is around 10,000 K, and it tends to increase as the tube inner diameter becomes narrow and/or the arc current increases. The overall temperature distributions from the arc axis to the tube wall are obtained by combining these inner temperature distributions with outer temperature distributions which have been derived from C2 spectra. They are found to take a form of typical two‐temperature distributions of ablation stabilized arcs. The electric field strengths of PE arcs are evaluated from the temperature distributions and the electrical conductivity versus temperature characteristics of thermally decomposed polyethylene vapor gas. The results agree well with experimental values.
