When supply voltage, respectively 15 and 5 kV kV, 40 Min, and the power lab results showed that there are burrs from the middle connector local field strength increases, the partial discharge than burr intermediate connector temperature, high 2.45 °C C 4.31 °.

When the power line voltage respectively is 5kV and 15kV, adds electricity 40min, the experimental result indicated that, because has the burr middle attachment the partial field intensity ascension to appear the shelf depreciation phenomenon, distinguishes high compared to the burr-free middle atta

When the power supply voltage of 5kV and 15kV respectively, plus 40min, experimental results show that Burr rise in the joints due to local field partial discharge phenomena, 2.45 respectively than the Burr-free joints temperature ℃, 4.31 ° c.
