Description

{POWER DISTRIBUTION BOX FOR UNDERGROUND DISTRIBUTION LINE OF APARTMENT}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch distribution box for a subdivision power distribution line of a dwelling house, in which a power line connected to each household is periodically rotated in a rotating manner to facilitate separation and replacement of the power line from the main body, To a branch distribution box of a sub-house underground distribution line in which insulation can be variably maintained in winter, while suppressing temperature rise.

Generally, the electricity used in the apartment house is supplied through the substations equipped for each region. These substations are installed for the purpose of modifying the voltage or current and distributing electric power.

In this case, in order to protect the power line from an external force, the power line which is converted into the commercial power from the substation is extended to the power distributing box and the inside of the pipe And installed in a circuit breaker installed in the cabinet with the power line inserted.

This branch distribution box supplies power to each household.

However, in the past, when power lines branched to each generation are fixed, when the power line abnormality occurs, the entire power distribution box must be repaired.

In addition, there is a problem that the electric power transmission part and the inside of the power distribution box are sealed, thereby raising the temperature, thereby causing overheating.

Therefore, it is required to develop a technology for an electric distribution box which can easily suppress the temperature rise while facilitating the repair, and can also easily heat insulation in winter.
