Abstract
The utility model relates to a temporary stainless steel grounding body device, and is characterized by comprising a stainless steel rod (3); wherein one end of the stainless steel rod (3) is provided with a handle (1), the stainless steel rod (3) is provided with a grounding wire board (2) near the handle (1), and the stainless steel rod (3) is a screw rod. By adopting the temporary stainless steel grounding body device of the utility model, time for installing a grounding body by a worker can be greatly reduced, a grounding area between the grounding body and soil is increased, a ground resistance is reduced, safety and reliability for personnel and equipment also can be realized; in addition, the temporary stainless steel grounding body device is capable of meeting construction and maintenance requirements, is convenient for supervising construction quality, and is capable of preventing the phenomenon that personal injury to maintenance personnel or construction personnel is caused by a discharge current or an induced current due to an insufficient burial depth, thus personal safety of the construction and maintenance personnel is affected.
Description
Technical field
The utility model relates to a kind of interim stainless steel earth electrode device.
Background technology
The temporary grounding body is the indispensable safety appliance that power construction, upkeep operation ground connection are used.When using the temporary grounding body, require the earth electrode buried depth to be not less than 60cm in " electric power safety working regulation circuit " (power circuit part), sectional area is not less than 190mm2.In the Shizuishan area, belong to stiff soil, sticking glutinous, frozen soil layer, rock more than 80% and be difficult to wedging, easily cause the earth electrode buried depth inadequate, earth resistance can not satisfy the rules requirement, cause easily discharge current or faradic injury, cause that human casualty accident occurs.When removing earth rod, because the earth electrode buried depth about 60cm, is difficult to transfer to smoothly, can only lose when can not pulling out, greatly incur loss through delay construction, service work time.
Illustrating that through for many years practice the soil property type has become a key factor that affects temporary grounding body safe and stable operation, causes the earth electrode earth resistance not satisfy the demand, and directly threatens personnel's life security.
The utility model content
The purpose of this utility model provides a kind of interim stainless steel earth electrode device, thereby can increase earth electrode and soil contact area minimizing earth resistance.
A kind of interim stainless steel earth electrode device, its special feature is: comprise a stainless steel, at this stainless steel one end handle is installed, the stainless steel other at this handle is equipped with the earth connection plate, and this stainless steel is screw rod.
Wherein have at least one through hole at the earth connection plate.
Wherein screw rod is solid stainless steel round bar, and is provided with spiral screw thread at this round bar.
The utility model relates to a kind of interim stainless steel earth electrode device, can greatly reduce the staff after the use time connect electric body is installed, and increases earth electrode and soil contact area, the minimizing earth resistance, and realization personnel, device security are reliable.Can also satisfy construction, maintenance needs, be convenient to supervise construction quality, prevent from causing discharge current or induced current to cause maintainer or workmen's loss of life or personal injury because buried depth is not in place impact construction, maintainer's personal safety.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of interim stainless steel earth electrode device, comprise a stainless steel 3, at these stainless steel 3 one ends handle 1 is installed, at this handle 1 other stainless steel 3 earth connection plate 2 is installed, be connected with earth connection thereby have at least one through hole at earth connection plate 2, and this stainless steel 3 is screw rod, specifically can adopt solid stainless steel round bar, and be provided with spiral screw thread at this round bar.
Characteristics of the present utility model are as follows:
Common earth electrode is because round steel is level and smooth, and contact area is little, and earth resistance is large; The utility model adopts the spiral earth electrode of stainless steel, increased the foundation area of earth electrode and the earth, (the earth electrode contact area increased about 1/3 more in the past), effectively reduce earth resistance, make grounding resistance descend 26%, avoided the injury to the workmen such as induced voltage, leakage current.In installation process, carry out power down after, only need with the hands hold handle 1 rotary screw type temporary grounding body and screw in soon in the ground, improved the fail safe of installation process, on not impact of line security operation.
Use spiral stainless steel earth electrode not only save time, laborsaving, and the fail safe that has greatly improved construction operation, repeat usage has reached 100%, has improved operating efficiency.To the temporary grounding body that needs are removed, with the hands can remove smoothly by just being rotated counterclockwise.Reduce the mounting or dismounting earth electrode time, improve the reliability index of distribution line.Reduce producers' labour intensity.Reduce the interruption duration of distribution line, reduce connecting resistance.Greatly avoided induced voltage, leakage current etc. that the construction operation personnel are injured.
Claims (3)
1. interim stainless steel earth electrode device, it is characterized in that: comprise a stainless steel (3), at these stainless steel (3) one ends handle (1) is installed, the stainless steel (3) other at this handle (1) is equipped with earth connection plate (2), and this stainless steel (3) is screw rod.
2. interim stainless steel earth electrode device as claimed in claim 1 is characterized in that: wherein have at least one through hole at earth connection plate (2).
3. interim stainless steel earth electrode device as claimed in claim 1 or 2, it is characterized in that: wherein screw rod is solid stainless steel round bar, and is provided with spiral screw thread at this round bar.
