<p>PROBLEM TO BE SOLVED: To provide a power receiving unit into which a cable can be led in both from upper and lower sides without increasing the depth dimension. SOLUTION: A lower chamber 13 and an upper chamber 14 are formed in the case 1 of a power receiving unit U11 and the component equipment of a receiving-side circuit including a circuit breaker CB and the like, and the component equipment of a bus-side circuit provided with two sets of buses BUS1 and BUS2 is housed in the lower chamber 13 and the upper chamber 14, respectively. The bus-side circuit and the receiving-side circuit are connected with each other through a feedthrough conductor installed in a spacer 16 that separates the lower chamber 13 and the upper chamber 14 from each other together with gases. The buses BUS1 and BUS2 are installed with the directions of installation of their respective three-phase bus conductors 25u to 25w and 27u to 27w orthogonal to each other, and a line lead-in chamber 18 extending from the lower end to the upper end of the case 1 is formed between the rear faces of the lower chamber 13 and upper chamber 14 and the rear face of the case 1.</p> |
