Abstract

The utility model relates to a 10kV overhead line fixed-point installation grounding device, aiming at solving the problems that the physical strength consumption of outdoor operating personnel is great, a grounding bar is apt to be damaged and the personal safety of the working personnel cannot be guaranteed during power maintenance. The ends of the three grounding hooks of the 10kV overhead line fixed-point installation grounding device are respectively and fixedly connected with one ends of corresponding three 10kV grounding bars. The other ends of the three 10kV grounding bars are suspended in the air. One ends of three 25mm<2> soft copper wires 3 are connected with the bodies of the three 10kV grounding bars. The other ends of the three 25mm<2> soft copper wires are connected with one ends of multiple strands of 25mm<2> soft copper wires. The 10kV overhead line fixed-point installation grounding device is applicable to the field of power inspection.

Description

10kV overhead transmission line fixed point is installed earthing device
Technical field
The utility model relates to the electric power overhaul field.
Background technology
At present, when spring, autumn, inspection line outage was overhauled, many circuits of stopping using, when going out operation, the staff carries many group 10kV short-circuit grounding wires, and every group of ground wire weight is carried inconvenient especially about 20 jin.When hanging ground-wire, upper and lower transmission ground wire also easily causes the earth connection insulating rod to damage, and is behind end-of-job by it, and operating personnel's physical demands is excessive, and when tearing ground wire open, ground wire comes off easily when down transmitting, and causes earth rod to damage.The staff often occurs hanging conductor wire end earlier when hanging earthing conductor in addition, and the back hangs the faulty operation of earth terminal, and human body electrification easily takes place.Intersecting, during many parallel circuit hanging ground-wires, also causing mistake to pedal bar easily, charged hanging ground-wire phenomenon takes place.
The utility model content
The utility model is when solving electric power overhaul, the operating personnel's physical demands of going out is big, earth rod is fragile, and the unexpected problem of harm staff's personal safety when incoming call and charged hanging earthing conductor during hanging ground-wire is installed earthing device thereby proposed 10kV overhead transmission line fixed point.
10kV overhead transmission line fixed point is installed earthing device, and this device comprises three ground connection hooks, three 10kV earth rods, three 25 square millimeters of annealed copper wires and 25 square millimeters of annealed copper wires of multiply,
The end of described three ground connection hooks is fixedly connected with an end of corresponding three 10kV earth rods respectively,
The other end of three 10kV earth rods is unsettled, and an end of three 25 square millimeters of annealed copper wires is connected with the excellent body of three 10kV earth rods respectively,
The other end of three 25 square millimeters of annealed copper wires is connected with an end of 25 square millimeters of annealed copper wires of multiply simultaneously.
10kV overhead transmission line fixed point is installed earthing device and is also comprised mounting panel and connector, and the material of described mounting panel and connector is insulating material, and connector is fixed in mounting panel top, three equidistant hanging on the connector of 10kV earth rod.
10kV overhead transmission line fixed point described in the utility model is installed head end and the end that earthing device is located at the 10kV overhead transmission line; and the head end and the end of 10kV overhead transmission line branched line; reduced the operating personnel's physical demands of going out; the end that the 10kV overhead transmission line fixed point of this device is installed 25 square millimeters of annealed copper wires of multiply of earthing device is connected by the earthing device of 25 square millimeters of round steel of diameter with place electric pole bottom; protection 10kV earth connection outward appearance is complete; 10kV overhead transmission line fixed point is installed earthing device and has been realized that in the electric power overhaul process earth rod does not have damage; suddenly the accident that accident that the electrification of sending a telegram here when avoiding hanging ground-wire is hurted sb.'s feelings and charged hanging earthing conductor are hurted sb.'s feelings.
Description of drawings
Fig. 1 is the structural representation that 10kV overhead transmission line fixed point described in the utility model is installed earthing device;
Fig. 2 installs earthing device for 10kV overhead transmission line fixed point and is installed in structural representation on the overhead transmission line, 7 expression ground loops among the figure, and 8 expression 10kV overhead transmission lines fixed points are installed earthing device, 25 square millimeters of round steel of 9 expression diameters.
Embodiment
Embodiment one, specify present embodiment in conjunction with Fig. 1, the described 10kV overhead transmission line of present embodiment fixed point is installed earthing device and is comprised three ground connection hooks 1, three 10kV earth rods 2, three 25 square millimeters of annealed copper wires 3 and 25 square millimeters of annealed copper wires 4 of multiply
The hook end of described three ground connection hooks 1 is used to connect overhead transmission line,
The end of three ground connection hooks 1 is fixedly connected with an end of corresponding three 10kV earth rods 2 respectively,
The other end of three 10kV earth rods 2 is unsettled, and an end of three 25 square millimeters of annealed copper wires 3 is connected with the excellent body of three 10kV earth rods 2 respectively,
The other end of three 25 square millimeters of annealed copper wires 3 is connected with an end of 25 square millimeters of annealed copper wires 4 of multiply simultaneously.
When present embodiment has realized the line outage operation, intuitively reflect the hanging ground-wire position, prevent the wrong extension of hanging ground-wire personnel or leak hanging earthing conductor that this apparatus structure is simple, and is easy for installation, practical.
The difference that embodiment two, present embodiment and embodiment one described 10kV overhead transmission line fixed point are installed earthing device is: it also comprises mounting panel 5 and connector 6, the material of described mounting panel 5 and connector 6 is insulating material, connector 6 is fixed in mounting panel 5 tops, three 10kV earth rod 2 equidistant hanging on the connector 6.
Head end and end at the 10kV overhead transmission line, and all be fixed with a 10kV overhead transmission line fixed point on the head end of 10kV overhead transmission line branched line and the terminal electric pole earthing device is installed, be provided with a ground loop 7 on every wire of this device top, be used for when being grounded, connect with three ground connection hooks in the device described in the utility model, realize the connection of lead ground connection, the end that each 10kV overhead transmission line fixed point is installed 25 square millimeters of annealed copper wires 4 of multiply of earthing device is connected by the earthing device of 25 square millimeters of round steel 9 of diameter with place electric pole bottom, realized that earth rod does not have damage, suddenly the accident that accident that the electrification of sending a telegram here when avoiding hanging ground-wire is hurted sb.'s feelings and charged hanging earthing conductor are hurted sb.'s feelings.
