Description
Technical field
The utility model belongs to substation grounding technical field, is specifically related to substation bus bar bridge earthing device.
Background technology
In electric power system, in order to prevent the short circuit of main transformer near region, cause the substantial equipment damage accident of transformer damage, 10kV bus bridge for transforming plant main transformer all insulate encapsulating, at present when main transformer interruption maintenance hanging earthing conductor, can only be that insulating bag closure cover is broken, expose conductor, hanging earthing conductor on conductor.
Prior art Problems existing: one is broken by insulating bag closure cover, needs staff to carry out, though can carry out electrical verification, there is the danger of induced electricity electric shock in the protection of no ground line; Two is that staff needs work high above the ground, there is the potential safety hazard of falling from high altitude; Three is after overhaul of the equipments completes, and also needs to carry out insulation encapsulating to exposed part, wastes time and energy, and can cause unnecessary waste; Four is that current existing earth connection is completely not corresponding with main transformer 10kV side conduit connection plate, causes hanging earthing conductor not in place, easily comes off, and there is the hidden danger affecting personal safety; Five is that 10kV bus bridge cannot electrical verification because of insulation encapsulating.
Summary of the invention
The purpose of this utility model overcomes weak point of the prior art, provides substation bus bar bridge earthing device.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
Substation bus bar bridge earthing device, comprise earth electrode, be characterized in: also comprise conductive base and insulation button box, described conductive base is the sheet material in L-type, the sheet material of this L-type is made up of electric conducting material, its horizontal component arranges the hole for connecting, and its vertical portion arranges the pedestal via hole penetrating earth electrode; Described insulation button box comprises at the bottom of box and lid, has via hole at the bottom of the box consistent with pedestal via hole in the middle part of at the bottom of described box, described lid edge by articulated mounting and box base along hinged; Described earth electrode is through via hole at the bottom of box and pedestal via hole and fix with conductive base, and described lid outer wall arranges the convex edge for opening box; Described conductive base horizontal component and bus bridge affixed after take insulating material to encapsulate; Described earth electrode and conductive base vertical portion affixed after take to insulate and encapsulate; Nose is buckled along arranging in described lid and box base.
Described button nose arranges magnetic pole.
The utility model compared with prior art has following beneficial effect:
Owing to adopting insulation button box to be surrounded by earth electrode, when needs ground connection, open insulation button box and just can carry out electrical verification, ground connection easily.When not needing ground connection, closing button box and then earth electrode being surrounded, safe and reliable, convenience and high-efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 be in Fig. 1 A-A to cutaway view.
In figure: 1-horizontal component; At the bottom of 2-box; 3-convex edge; 4-lid; 5-earth electrode; 6-vertical portion; 7-articulated mounting; 8-magnetic pole; 9-button nose.
Embodiment
As shown in Figure 1, substation bus bar bridge earthing device, comprise earth electrode 5, be characterized in: also comprise conductive base and insulation button box, described conductive base is the sheet material in L-type, the sheet material of this L-type is made up of electric conducting material, and its horizontal component 1 arranges the hole for connecting, and its vertical portion 6 arranges the pedestal via hole penetrating earth electrode 5; Described insulation button box to comprise at the bottom of box 2 and lid 4, has via hole at the bottom of the box consistent with pedestal via hole in the middle part of 2 at the bottom of described box, described lid edge by articulated mounting 7 with box base along hinged; Described earth electrode 5 is fixed through via hole at the bottom of box and pedestal via hole and with the vertical portion 6 of conductive base, and described lid 4 outer wall arranges the convex edge 3 for opening box; Insulating material is taked to encapsulate after described conductive base horizontal component 1 is affixed with bus bridge; Take to insulate after described earth electrode 5 is affixed with conductive base vertical portion 6 and encapsulate; At the bottom of described lid 4 and box, the edge of 2 arranges and buckles nose 9.
Described button nose 9 arranges magnetic pole 8.
Using method: this device is connected with bus bar by Luo bolt, and take insulation encapsulating.When needs ground connection, use insulating bar to stir convex edge 3, thus lid 4 is opened, expose earth electrode 5, earth connection is enclosed within earth electrode 5; When not needing ground connection, taking off earth connection, lid 4 to be covered at the bottom of box on 2.
