範囲第１項記載の全地中形高圧多回路開閉器。[Scope of Claim for Utility Model Registration] 1. A sealed switch installed in a manhole, which further has a pressure relief port formed on the top surface of the case of the switch due to a sudden increase in pressure within the case. In a fully underground high-voltage multi-circuit switch equipped with a pressure relief device that releases the same pressure from the pressure relief port to the outside of the case, there is some pressure relief space on the top surface of the case. An all-underground high-voltage multi-circuit switch that is characterized by being equipped with a pressure relief deflection plate that covers the entire upper surface and doubles as a work platform. 2. The fully underground high-voltage multi-circuit switch according to claim 1, wherein the pressure relief deflection plate is a steel plate with anti-slip applied on its upper surface.
