Abstract
The utility model relates to an electrical supply equipment of an electric power system, in particular to a protective shield of the ground terminal of a ground wire of an anti-misoperation and lockout device, which comprises a screw bolt (9), a butterfly nut (10), a grounding end-plate (8) of the anti-misoperation and lockout device, a supporting structure (7), a ground terminal (11) and a folding (3), wherein a groove-shaped fixed shield (4) is fixed on the supporting structure (7), a gap (4-1) whose shape is corresponding with that of the grounding end-plate (8) of the anti-misoperation and lockout device is arranged on the front surface of the fixed shield (4), and a gap (4-2) whose shape is corresponding with that of the ground terminal (11) is arranged on the lower side surface, a lock plate II (5) is fixed on the right side surface, the folding (3) is arranged on the left side edge of the fixed shield (4), and the folding (3) is connected with a movable shield (2). The protective shield of the ground terminal of the ground wire of the anti-misoperation and lockout device enables the assembly and the disassembly of the ground wire to be very convenient, the safety is increased, the price is low, and the electrical supply equipment can be widely applied in the examination and repair of power supply and power transformation.
Description
Technical field
The utility model belongs to power system power supply equipment, particularly a kind of anti-misoperation locking device ground connection end protective cover.
Background technology
Whether need hanging earthing conductor in substation equipment maintenance and repair work, whether the ground connection end of installation is firm, be directly connected to earth connection and play a protective role.And used anti-misoperation locking device earth terminal just exists deficiency in the substation equipment maintenance and repair work now, the earth terminal of earth connection only uses wing nut fastening, the effect of anti-error lock just prevents to install and take down the earth terminal of earth connection, in case during normal use running into the external force effect, earth connection will cause wing nut loosening, make the earth terminal loose contact of earth connection, particularly when 220 kilovolts of equipment availabilities, electrostatic induction own is just strong, can directly have influence on staff's life security.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of installing/dismounting earth connection convenient, the anti-misoperation locking device ground connection end protective cover that security performance is good.
The technical scheme that the utility model technical solution problem adopts is: anti-misoperation locking device ground connection end protective cover is by screw rod; wing nut; anti-misoperation locking device ground connection end plate; fixed mount; earth terminal and folding are formed; be characterized on fixed mount, fixing a flute profile fixed cover; on the fixed cover front, establish a gap with anti-misoperation locking device ground connection end plate similar shape shape; establish on the downside and the gap of earth terminal with shape; fixing jam plate two on right flank; on fixed cover left surface edge, adorn folding; folding connects movable guard; correspondingly on the movable guard right side fix a jam plate one with jam plate two; movable guard front front end is made cylindrical shape and is established a movable guard hole at the front end face center; screw rod passes the movable guard hole; be provided with screw hole at the screw front end head; install lock ring in the screw hole, on the movable guard downside, establish corresponding gap with shape with fixed cover.
The utility model beneficial effect is: anti-misoperation locking device ground connection end protective cover makes the installation and removal earth connection very convenient, has increased fail safe, and is cheap, can extensive use in the power supply substation equipment maintenance and repair.
