Description
Technical field
The utility model belongs to electrical facility technical field, particularly relates to one " h " shape ground wire fixing device.
Background technology
In electric power system, partial earthing line needs to be attached on building walls, once ambient humidity is larger, building walls just there will be the moist phenomenon of condensation, earth connection will be made like this to produce corrosion, result causes earth connection dynamic and thermal stability electric current not meet the demands, thus the safe and stable operation of the equipment of giving brings great hidden danger.
Specify according to " erection works of electrical installations code for construction and asseptance of earthed devices " GB50169 1, the installation gap that should meet between earth connection and building walls of surface earth connection is the requirement of 10-15mm.Therefore if the distance of building walls and earth connection is standardized, effectively can reduce the earth connection corrosion phenomena caused because of wall moisture issues, thus greatly can increase service life of equipment, improve the operational reliability of equipment.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of " h " shape ground wire fixing device.
In order to achieve the above object, " h " shape ground wire fixing device that the utility model provides comprises fixed head, earth connection grip block, expansion bolt and jackscrew; Wherein earth connection grip block is the inverted L-shaped plate be made up of level board and vertical panel, and the outer end of level board is connected in the middle part of the outer surface of fixed head, and the lower parallel of vertical panel and fixed head is arranged; Expansion bolt runs through fixed head top and arranges; Jackscrew runs through vertical panel and arranges.
The thickness of described fixed head is 15mm, and the distance between fixed head and vertical panel is 6mm.
" h " shape ground wire fixing device that the utility model provides is reasonable in design, structure is simple, easy to operate and attractive in appearance, earth connection installation specification, standardization can be made, efficiently solve wall moisture-induced earth connection corrosion problem, ensure that earth connection conducting is good, dynamic and thermal stability performance meets the demands, thus improves the operational reliability of equipment.
Accompanying drawing explanation
" h " shape ground wire fixing device front view that Fig. 1 provides for the utility model.
" h " shape ground wire fixing device vertical view that Fig. 2 provides for the utility model.
" h " shape ground wire fixing device vertical structure cutaway view that Fig. 3 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, " h " shape ground wire fixing device that the utility model provides is described in detail.
As shown in Fig. 1-Fig. 3, " h " shape ground wire fixing device that the utility model provides comprises fixed head 1, earth connection grip block 2, expansion bolt 3 and jackscrew 4; Wherein earth connection grip block 2 is the inverted L-shaped plate be made up of level board 5 and vertical panel 6, and the outer end of level board 5 is connected in the middle part of the outer surface of fixed head 1, and vertical panel 6 is arranged with the lower parallel of fixed head 1; Expansion bolt 3 runs through fixed head 1 top and arranges; Jackscrew 4 runs through vertical panel 6 and arranges.
The thickness of described fixed head 1 is 15mm, and the distance between fixed head 1 and vertical panel 6 is 6mm.Can ensure that the distance between earth connection and building walls meets set quota in " erection works of electrical installations code for construction and asseptance of earthed devices " GB50169 1 like this.
" h " shape ground wire fixing device using method now provided by the utility model is described below: first on building walls, determine the fixed installation point needed for earth connection by staff, then boring bar tool is used to hole at above-mentioned fixed installation point place, expansion bolt 3 is utilized to be anchored on building walls by fixed head 1 afterwards, arrange earth connection afterwards, and earth connection is inserted in the opening between vertical panel 6 and fixed head 1 bottom, fastening jackscrew 4, reliably fixes earth connection thus afterwards.
