The utility model provides a become hot switching path of platform low voltage distribution box on 10kV integration post, its characterized in that: including the S -shaped heat dissipation channel that sets up at the block terminal top with set up the gaseous switching path at distribution upset frame frame both sides wall, in outside air passing through gases switching path got into the block terminal, components and parts in the block terminal were sent out thermogenetic the heat and are passed through the outflow of S -shaped heat dissipation channel, form gaseous switching path promptly inside the block terminal the hot switching path of S -shaped heat dissipation channel.
