Abstract
The utility model relates to a grounding electrode, which solves the technical problems that the existing grounding electrode is unreasonable in designing the striking head section so that it is easy to hit a user when hitting the striking head by using a hammer and so on, and that the existing grounding electrode is nonuniform in length and has no buried depth mark so that a work staff and a security supervisor are difficult to check whether the buried depth meets the requirement. The grounding electrode provided by the utility model comprises a grounding body, and a striking head above the grounding body, wherein the grounding body is a columnar copper bar with a diameter of 5cm; a scale is graduated as a buried depth mark on the grounding body at a position of 60 cm away from the tail end of the grounding body; and a scale is also graduated at a position of 70cm away from the tail end of the grounding electrode. The area of the striking head is enlarged, so that the grounding electrode is more convenient to be inserted into the ground, and the striking head is soldered after drilling so as to prevent unsoldering. The grounding electrode is determined qualified when the supervisor only sees the 70cm scale but does not see the 60cm scale during checking, thereby providing convenience for constructors and security supervisor in checking the buried depth of the grounding electrode.
Description
Technical field
The utility model belongs to the improvement of grounding electrode equipment, relates in particular to a kind of novel grounded utmost point.
Background technology
In power supply enterprise's construction operation, for guaranteeing workmen's safety, prevent that the unexpected incoming call of circuit from causing human casualty accident, earth connection is widely used.Regulation in " State Grid Corporation of China's electric power safety working regulation (power circuit part) ": ", can adopt the temporary grounding body for the shaft tower of no earth connection downlead.The sectional area of earth electrode must not be less than 190mm
2Earth electrode must not be less than 0.6m in the underground degree of depth." by this regulation, the temporary grounding body must cuttage be gone into ground, and buried depth must not be lower than 0.6m.In real work, find following problem: present most of earth connection manufacturer pays little attention to the design of earth electrode; The place's sectional area of raming is too small; Be difficult for making the earth electrode cuttage to go into ground, and the major part sectional area of raming is the sectional area of earth electrode, hammer etc. knock to ram to strike partially easily and hurt sb.'s feelings; The 2nd, earth electrode length disunity does not have the buried depth sign, and staff and safety monitor personnel are difficult to check whether buried depth meets the requirements.
The utility model content
It is unreasonable that the utility model will solve the earth electrode partial design of raming exactly; Hammers etc. knock to strike easily when raming and hurt sb.'s feelings partially and earth electrode length disunity; There is not the buried depth sign; Staff and safety monitor personnel are difficult to check whether satisfactory technical problem of buried depth, and a kind of novel grounded utmost point is provided.
In order to solve the problems of the technologies described above; The utility model provides a kind of novel grounded utmost point; Have earth electrode and be positioned at raming of earth electrode top; It is characterized in that: said earth electrode is the cylindrical copper rod of diameter 5cm, apart from the terminal 60cm mark of earth electrode scale buried depth sign, is also marking scale apart from the terminal 70cm of earth electrode place.
Adopt the beneficial effect of technique scheme: this novel grounded utmost point, have and ram, the sectional area of raming increases greatly, and ground is gone in more convenient cuttage, and because the welding of punching back is difficult for sealing-off after the welding.Earth electrode is provided with two graduation marks, when inspection, sees the 70cm scale, and can't see the 60cm scale, and it is qualified to think, like this, just very convenient during the buried depth of workmen and safety supervision personnel inspection earth electrode.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is existing earth electrode outline drawing.
Fig. 2 is the earth electrode outline drawing after improving.
Embodiment
Existing earth electrode as shown in Figure 1 only has an earth electrode, has no mark on it, is not sure of the earth electrode cuttage in use and goes into the underground degree of depth, uses inconvenience.A kind of earth electrode of the utility model as shown in Figure 2; Have earth electrode be positioned at earth electrode top ram 3; Said earth electrode is the cylindrical copper rod of diameter 5cm, apart from the terminal 60cm mark of earth electrode scale buried depth sign 1, is also marking scale 2 apart from the terminal 70cm of earth electrode place.3 sectional areas of raming increase greatly, and ground is gone in more convenient cuttage, and because the welding of punching back is difficult for sealing-off after the welding.Apart from the terminal 60cm of earth electrode place, mark scale as the buried depth sign, also marking scale, so that inspection apart from the terminal 70cm of earth electrode place.See the 70cm scale during inspection, and can't see the 60cm scale, it is qualified to think.Like this, just very convenient during the buried depth of workmen and safety supervision personnel inspection earth electrode.
Claims (1)
1. a novel grounded utmost point has earth electrode and is positioned at raming of earth electrode top, and it is characterized in that: said earth electrode is the cylindrical copper rod of diameter 5cm, apart from the terminal 60cm mark of earth electrode scale buried depth sign, is marking scale apart from the terminal 70cm of earth electrode place.
