The utility model provides an improved PT1 type power distribution station. A 10 kV inlet wire is communicated to a transformer through a 10 kV load switch, and the transformer enables a 10 kV inlet wire voltage to be converted into a 0.4 kV voltage and then to be output. Furthermore, a 0.4 kV switch is used for being communicated with a 0.4 kV busbar, a plurality of outgoing wires arranged below the 0.4 kV busbar are respectively provided with an outgoing wire switch, and a set of 0.4 kV capacitors are connected to the 0.4 kV busbar through a capacitor switch. The 10 kV load switch is arranged on an SF6 ring main unit, and the 0.4 kV switch, the outgoing wire switch and the capacitor switch are arranged on a vacuum circuit breaker of a GGD cabinet. According to utility model, under the premise that an original scale and a main wiring mode are not changed, primary equipment of the power distribution station is replaced, the health level and the safety operation level of the equipment can be better improved, t
