METHOD OF INSTALLATION OF SAFETY VALVE OF DIRECT CURRENT Russian patent published in 2019 - IPC B23P21/00 H02M7/00 

FIELD: electricity.

SUBSTANCE: invention relates to a method of mounting a DC safety valve. Installation of upper protective casing (2): lifting of upper protective casing to preset height by means of lifting platform (6); after that, rigid connection of upper protective casing with lower ends of insulators (7) is performed, rigid connection of upper ends of insulators with truss (1). Truss is located in the upper part of the room where the valve is installed. Installation of valve shells: alternate lifting of valve covers (5), from top to bottom, in specified places by means of lifting platform. Installation of the lower protective casing: it is necessary to raise the lower protective casing to the specified height by means of the lifting platform, to fix this element to the lowest casing of the valve and to hang it under it with the help of suspension insulators.

EFFECT: due to use of similar solution, simplified process of units operation, reduced number of used devices, and also increased level of safety and reliability of equipment.
