Cable branch box mechanical interlock operation device

Abstract

The invention discloses a mechanical interlocking operation device for a cable branch box, which relates to the technical field of manufacturing of high-voltage electrical equipment. The mechanical interlocking operation device comprises an outer box, a switch cabinet in which a load switch and a load switch operation mechanism are installed, a switch operation shaft arranged on the operation mechanism, a door lock arranged on the outer box, as well as an upper lock rod and a lower lock rod which are connected with the door lock, wherein the operation shaft is movably connected with a switch cabinet mechanical lock arranged in the switch cabinet, and the switch cabinet mechanical lock is movably connected with a mechanical lock key; the mechanical lock key is movably connected with a branch box mechanical lock installed on the outer box; the branch box mechanical lock is connected with the door lock; the upper lock rod and the lower lock rod are connected with a top rod respectively; the upper lock rod and the lower lock rod are further movably connected with a lock clamp arranged on a box body of the outer box. The mechanical interlocking operation device is capable of solving the problems of high production cost, and difficulty in installation and operation, of the cable branch box while meeting five-prevention requirements.

Description

technical field [0001] The invention relates to the technical field of manufacturing high-voltage electrical equipment, in particular to a mechanical interlocking operation device for a cable branch box. Background technique [0002] At present, there is no interlocking device in the cable branch box, switch cabinet and the high-voltage room part of the outgoing line in the power distribution system. Generally, sheet metal and bolts are used to tighten each other to achieve the effect of isolating the high-voltage part, but this method is far from being true. Isolate the five anti-functions of high pressure, ordinary tools can unscrew the bolts, and come into contact with high pressure. If the high pressure part is sealed, it will bring a lot of trouble to maintenance and cause poor versatility of the unit and high production cost. These technical solutions are either too complicated or difficult to install and operate. Contents of the invention [0003] The purpose of th...
