A power receiving and transforming device with a power-fuse insulated by gas is provided to minimize the scale of accident by safely emitting gas when inner pressure is raised over predetermined pressure. A power receiving and transforming device with a power-fuse insulated by gas includes a power receiving and transforming plate(A) and a power transforming plate(B). In the power receiving and transforming plate(A), an insertion hole(11) receives power from a distribution line. An automatic section switch(13) is connected to the lower part of the insertion hole(11). An arrester(15) and a power fuse(17) are connected to the lower part of the automatic section switch(13). A current transformer for supplying electricity(19) is connected to the lower part of the power fuse(17). A watt-hour meter(21) measures the amount of power by being connected to the current transformer for supplying electricity(19). In the power transforming plate(B), a gas insulation type power fuse(23) has power fuse members(23a,23b) of corresponding number to the power receiving and transforming plate(A) and the power transforming plate(B). The power receiving and transforming plate(A) and the power transforming plate(B) include transformers(25a,25b) connected to the lower parts of the power fuse member(23a,23b), main circuit breakers(27a,27b) connected to secondary sides of the transformer(25a,25b), and a plurality of circuit breakers(29a,29b) connected to the main circuit breakers(27a,27b) and intercepting each load in case of need. |
