Description
Technical field
The utility model relates to transformer station's technical field, relates in particular to a kind of substation equipment ground structure.
Background technology
Ground connection in transformer station is a very important job, and the quality of ground connection is directly connected to equipment and personal safety.Along with continuing to increase of the development of electrical network, particularly system short circuit capacity, power plant electric substation more and more comes into one's own to the reliable degree of ground connection.
In order to ensure the reliability of equipment ground, existing earthing mode is all that plant bottom case is directly connected with earth electrode, then earth electrode is introduced to underground electrical network.Because plant bottom case is directly connected with underground electrical network, the length of General Requirements earth electrode is long, gives and installs, overhauls and all bring very big inconvenience.
Utility model content
Because the above-mentioned defect of prior art the utility model proposes one simple in structure, install, overhaul all substation equipment ground structure eaily.
For achieving the above object, the utility model provides a kind of substation equipment ground structure, comprises equipment, earth electrode and underground network system, and one end of described earth electrode is connected with described underground network system, also comprise metal earthing member and equipment supporter, described metal earthing member is channel-section steel; The web of described channel-section steel offers two connecting holes for being connected with the other end of described earth electrode; The web of described channel-section steel is connected with the other end bolt of described earth electrode; Described equipment frame is located on described equipment supporter, and the edge of a wing of described channel-section steel is connected by welding manner with described equipment supporter.
Further, described earth electrode is band steel, copper bar or the copper braid over braid with jointing clamp.
Further, described channel-section steel is No. 8 channel-section steels, described in be opened in the described connecting hole of the web of channel-section steel aperture be 13mm.
The beneficial effects of the utility model:
Substation equipment ground structure of the present utility model, owing to being provided with ground fitting between plant bottom case and earth electrode, earthing member is connected with earth electrode bolt, thereby can as required plant bottom case be connected or be disconnected with underground network system, simplify working procedure, improved the convenience of ground structure maintenance, maintenance.
Because earthing member is channel-section steel, simple in structure, easy to use, connect reliable.The welding of earthing member and equipment or equipment supporter can complete in precast plant, thereby has saved the engineering time, has improved operating efficiency.
The welding connecting mode of earthing member structure has further ensured the reliability that ground structure connects, and has reduced because ground structure connects the improper problem that may cause, has improved the reliability of ground structure.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 is the present embodiment substation equipment earthing member structural representation;
Fig. 2 is the present embodiment substation equipment ground structure schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of substation equipment ground structure, comprise equipment 2, as the channel-section steel 1 of earthing member, as band steel (not shown) and the underground network system (not shown) of earth electrode, wherein one end of band steel is connected with underground network system.
The web 11 of channel-section steel 1 offers two connecting holes 12 for being connected with the other end of band steel, when installation by bolt through the respective aperture on this connecting hole and band steel, screw with nut.This channel-section steel is preferably channel-section steel No. 8, and the diameter in hole is taking 13mm as best, and this size can ensure the bonding strength of channel-section steel and connector, and the distance between channel-section steel two edges of a wing can ensure to screw the required space of nut.Need to dismantle time, the nut of outwarding winding, unclamps earth electrode.
In order further to improve the convenience that ground structure uses, be provided with equipment supporter in device bottom, equipment frame is located on equipment supporter.In order to ensure the fastness of channel-section steel and equipment supporter welding, the edge of a wing of channel-section steel is connected by welding connecting mode with equipment supporter.
In addition, because channel-section steel is shorter, the welding sequence of channel-section steel and equipment supporter can complete in precast plant, thereby has simplified on-the-spot working procedure, has lowered difficulty of construction.Meanwhile, because band steel and equipment supporter are Split type structure, transport, maintenance and maintenance are all more convenient.
In other embodiments, earth electrode can be also copper bar or the copper braid over braid with jointing clamp.
In other embodiments, earth electrode can be two, and one of them earth electrode is connected with underground network system by the band steel that is welded in equipment supporter bottom, and another earth electrode is connected with equipment supporter top by the band steel that is welded in equipment supporter top.
Substation equipment ground structure of the present utility model, owing to having set up earthing member between equipment and earth electrode, thereby has improved the convenience of ground structure transport, construction, M R.
Earthing member has further ensured with the welding connecting mode of earth electrode the reliability that ground structure is connected, and has reduced because ground structure connects the improper problem that may cause, has improved the reliability of ground structure.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection range of claims.
