Abstract

The utility model discloses a transformer station tubular busbar double-clamp grounding device. The device comprises two hoop clamps and a grounding wire bar, wherein the hoop clamp includes an upper hoop clamp piece and a lower hoop clamp piece, two ends of the upper hoop clamp piece are connected with two ends of lower hoop clamp piece by locking screws, the lower hoop clamp pieces each is provided with a hanging arm, the hanging arms are connected by a rod, and the grounding wire bar is hung on the rod. For a small tubular busbar, the grounding wire hanging device is usually a flat-type or double-spring-hook-type wire clamp which has a small aperture and cannot be hung, a single-clamp grounding device is used, arc on the bottom of the semicircle clamp is short, and the grounding wire bar cannot be hung. According to the utility model, the double grounding hoop clamps are arranged on the transformer station busbar, the lower hoop clamp pieces are provided with the hanging arms, the hanging arms are connected by the rod, and the grounding wire bar is hung on the rod, so that the power personnel can conveniently mounting the grounding wire bar.

Description

The two clip earthing device of a kind of transformer station tube type bus
Technical field
The utility model belongs to the electric power overhaul equipment technical field, particularly the two clip earthing device of a kind of transformer station's tube type bus.
Background technology
Transforming plant main transformer depressor 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 the ground connection disconnecting link; 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 big; cause various earth connections all can't directly be suspended on the tube type bus; for the ultra-large type tube type bus, can use single deck tape-recorder hoop earthing device, but for small-sized tube type bus; because the earth connection suspension arrangement is flat or two-man act hook-type wire clamp; bore is less, can't hang, and adopts single deck tape-recorder hoop earthing device; semicircle hoop lower end camber line is short; use the earth connection rod not hang, make the operating personnel lose the protection of earth connection, personal safety can not get guaranteeing.
The utility model content
The utility model provides a kind of convenient transformer station's tube type bus single deck tape-recorder hoop earthing device quick, accurate, safe, firm in structure of earth connection that hangs.
The two clip earthing device of a kind of transformer station tube type bus, comprise 2 anchor ears and earth connection rod, described anchor ear comprises anchor ear sheet and following anchor ear sheet, described going up between anchor ear sheet and the following anchor ear sheet two ends is connected by clamping screw, described anchor ear sheet down is provided with arm, connect by the body of rod between the described arm, described earth connection rod card hangs on the described body of rod.
Described earth connection rod one end is provided with LED lamp and power supply, and this LED lamp is provided with switch, is connected by lead between described switch and described LED lamp and the power supply.
Described power supply adopts lithium battery.
The utility model is achieved in that described anchor ear comprises anchor ear sheet and following anchor ear sheet, is connected by clamping screw between anchor ear sheet and the following anchor ear sheet two ends on described, can make things convenient for the electric power personnel that adjusting is installed; For small-sized tube type bus, because the earth connection suspension arrangement is flat or two-man act hook-type wire clamp, bore is less, can't hang, adopt single deck tape-recorder hoop earthing device, semicircle hoop lower end camber line is short, uses the earth connection rod not hang, by two clampings ground anchor ear is set at transformer station's tube type bus, described anchor ear sheet down is provided with arm, connect by the body of rod between the described arm, described earth connection rod card hangs on the described body of rod, can make things convenient for the electric power personnel that the earth connection rod is installed; After using this earthing device, the operator on duty of transformer station can finish at tube type bus earth connection work is installed 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, the two clip earthing device of a kind of transformer station tube type bus, comprise 2 anchor ears 1 and earth connection rod 7, described anchor ear 1 comprises anchor ear sheet and following anchor ear sheet, described going up between anchor ear sheet and the following anchor ear sheet two ends is connected by clamping screw, described anchor ear sheet down is provided with arm 3, connect by the body of rod 4 between the described arm 3, described earth connection rod 7 cards hang on the described body of rod 4, described earth connection rod 7 one ends are provided with LED lamp 8 and power supply 6, this LED lamp 8 is provided with switch 5, is connected by lead between described switch 5 and described LED lamp 8 and the power supply 6, and described power supply adopts lithium battery.
The utility model is achieved in that described anchor ear comprises anchor ear sheet and following anchor ear sheet, is connected by clamping screw between anchor ear sheet and the following anchor ear sheet two ends on described, can make things convenient for the electric power personnel that adjusting is installed; For small-sized tube type bus, because the earth connection suspension arrangement is flat or two-man act hook-type wire clamp, bore is less, can't hang, adopt single deck tape-recorder hoop earthing device, semicircle hoop lower end camber line is short, uses the earth connection rod not hang, by two clampings ground anchor ear is set at transformer station's tube type bus, described anchor ear sheet down is provided with arm, connect by the body of rod between the described arm, described earth connection rod card hangs on the described body of rod, can make things convenient for the electric power personnel that the earth connection rod is installed; After using this earthing device, the operator on duty of transformer station can finish at tube type bus earth connection work is installed as requested fast, guarantees that the operating personnel works in the protection range of earth connection, protection operating personnel's personal safety.
