What is the reason for the electrification of the shell of the experimentell elektrisk ugn för hög temperatur?

There may be line leakage or static electricity when the shell of the high temperature experimental electric furnace is charged. When it is found that the shell of the high temperature experimental electric furnace is charged, the following inspections can be carried out:

1. Check whether the power supply line is damaged or connected to the chassis with wire drawing.

2. Check whether the ground wire of the power supply is in reliable contact or is missing.

3. Dry air and static electricity.
