Description

A kind of transformer station tube type bus single deck tape-recorder hoop earthing device
Technical field
The utility model belongs to electrical equipment technical field, particularly a kind of transformer station tube type bus single deck tape-recorder hoop earthing device.
Background technology
Hanging earthing conductor is one safety curtain of protection maintainer, can prevent the injury of incoming call to human body suddenly.But in real work, seem simple because earth connection uses frequent and operates, easily make the people produce decline in alertness; its importance is also often ignored by the people; incorrect operating position often occurs, so that reduce the safeguard protection effect that has even sometimes lost earth connection, must cause enough attention.Hanging earthing conductor is important technical measures for electric safety, its operating process should be strictly, conscientious, meet demand of technical standard, ten million can not careless general idea.Hanging earthing conductor is the safety precaution of adopting after power failure, if do not use or incorrect use earth connection, tends to add major break down infringement odds.
Main transformer of transformer substation mesolow side adopts tube type bus to be connected with indoor high-tension apparatus; when the main transformer body has power failure work; " safety " requires staff's working range must be in the earthing device protection range; each side of main transformer need hang earth connection or push to grounding switch; at present; because the earth connection suspension arrangement is flat or two-man act hook-type wire clamp; bore is less; and the tube type bus diameter is very large; cause various earth connections all can't directly be suspended on tube type bus; make the operating personnel lose the protection of earth connection, personal safety can not be guaranteed.
The utility model content
The utility model provides a kind of and has hung that earth connection is quick, accurate, safe, transformer station's tube type bus single deck tape-recorder hoop earthing device of highly versatile.
A kind of transformer station tube type bus single deck tape-recorder hoop earthing device, comprise anchor ear and earth connection rod, described anchor ear comprises two semicircle hoops, described semicircle hoop two ends connect by clamping screw, described semicircle hoop both sides, lower end are provided with arm, connect by the body of rod between described arm, described earth connection rod card hangs on the described body of rod.
Be provided with nut on described bolt, be provided with turning arm on this nut.
The all sides of described arm are provided with insulating barrier.
The utility model connects by clamping screw between described semicircle hoop by single deck tape-recorder hoop ground connection anchor ear is set on transformer station's tube type bus, can facilitate the electric power personnel that adjusting is installed; Be provided with nut on described bolt, be provided with turning arm on this nut, facilitate electric power personnel quick adjustment bolt, reduce senior engineer's task difficulty and operating time, be conducive to guarantee electric power personnel's personal safety; Described semicircle hoop both sides, lower end are provided with arm, connect by the body of rod between described arm, and described earth connection rod card hangs on the described body of rod, facilitates the electric power personnel that the earth connection rod is installed; The all sides of described arm are provided with insulating barrier, and the convenient working personal security is installed; After using this earthing device, the operator on duty of transformer station can complete earth connection work is installed on tube type bus as requested fast, guarantees that the operating personnel works in the protection range of earth connection, protection operating personnel's personal safety.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of transformer station tube type bus single deck tape-recorder hoop earthing device, comprise anchor ear 1 and earth connection rod 4, described anchor ear 1 comprises two semicircle hoops, connects by clamping screw 2 between described semicircle hoop, and the described semicircle both sides, lower end of binding round are provided with arm 3, connect by the body of rod 5 between described arm 3, described earth connection rod card 4 hangs on the described body of rod 5, is provided with nut 6 on described clamping screw 2, is provided with turning arm 7 on this nut 6.
The utility model connects by clamping screw between described semicircle hoop by single deck tape-recorder hoop ground connection anchor ear is set on transformer station's tube type bus, can facilitate the electric power personnel that adjusting is installed; Be provided with nut on described bolt, be provided with turning arm on this nut, facilitate electric power personnel quick adjustment bolt, reduce senior engineer's task difficulty and operating time, be conducive to guarantee electric power personnel's personal safety; Described semicircle hoop both sides, lower end are provided with arm, connect by the body of rod between described arm, and described earth connection rod card hangs on the described body of rod, facilitates the electric power personnel that the earth connection rod is installed; After using this earthing device, the operator on duty of transformer station can complete earth connection work is installed on tube type bus as requested fast, guarantees that the operating personnel works in the protection range of earth connection, protection operating personnel's personal safety.
