Inflation tankInsufficient lifting spacing or gas gap: insufficient climbing distance and too large gas gap are the key reasons leading to damage to the insulation of the inflatable cabinet; Especially in the hand cabinet, in order to reduce the specifications of the cabinet, greatly reducing the isolation switch installed in the cabinet; The spacing between the protective sockets or the spacing to the ground, but no measures are taken to ensure the compressive strength of the insulation.
The inflatable cabinet contact working capacity is not enough or loose: when the contact volume is not enough or loose, part of the temperature rises; When the contact is relatively serious, part of the current carrier burns, causing the grounding device or phase flashover, resulting in insulation flashover; Previous information said that the pile head heat under the brake caused a short circuit fault in the distribution power station, causing a fire accident and explosion.
