In real work, operations staff can take to open by force the method for intermediate switchgear cabinet rear enclosed chamber conventionally, cuts open the thermoplastic tube being wrapped on bus, then hangs conventional earth connection, to realize reliable ground.The practice has been run counter to the safety Design of switchgear like this, has violated electric power safety countermeasure, has strengthened operating personnel's security risk.And this provisional method needs again to fill the insulating barrier on bus surface after operation completes, trouble, has also increased cost of equipment maintenance extremely.
Summary of the invention
The utility model object is to overcome prior art defect, provides a kind of simple in structure, easy to use, handling safety reliably for the busbar grounding line of 10-35kV intermediate switchgear cabinet.
For achieving the above object, the utility model is by the following technical solutions:
For a busbar grounding line for 10-35kV intermediate switchgear cabinet, comprise insulated handle and be arranged on the earth connection inserted sleeve of insulated handle end for being connected with switch cabinet bus side contact, earth connection inserted sleeve is connected with earth connection; Described earth connection inserted sleeve is the conductive drum that is fixed on insulated handle end, along conductive drum, axially offer several flutings, conductive drum is divided into several lobes, near conductive drum leading section, along cylinder excircle, be provided with a cast groove, in cast groove, be arranged with for tightening up the spring banding of conductive drum.
Described earth connection inserted sleeve offers six flutings of arranging along even circumferential vertically, and conductive drum is divided into uniform six lobes.
Described earth connection afterbody is provided with fastening bolt, and earth connection is fixed on earth connection inserted sleeve by fastening bolt.
Described earth connection inserted sleeve adopts copper product to make.
Described earth connection is copper core plastic insulated conductor.
When using the utility model, first 10-35kV intermediate switchgear cabinet car switch is pulled to maintenance position, take out car switch, use instrument is opened the isolation baffle plate of switch cabinet bus side contact completely, expose bus bar side three-phase contact, by three busbar grounding lines of the present utility model by separate three contacts of bus bar side that insert successively, earth connection is fixed on to switch-cabinet grounding end, realize switch cabinet bus reliable ground, can meet 10-35kV intermediate switchgear cabinet safe design operation requirements, can meet the grounding requirement of bus again, not only improved the fail safe of the use of 10-35kV intermediate switchgear cabinet, also strengthened the reliability of ground connection.
The beneficial effects of the utility model are as follows:
1, compare traditional earthing mode, scene makes operating personnel away from charged positions such as switch cubicle sealing chambers, greatly reduces the security risk of personnel and equipment.
2, contact adopts particular design, conductive drum is divided into several lobes, near in conductive drum leading section cast groove, be arranged with for tightening up the spring banding of conductive drum, after joint engages with contact, joint cylinder is tightened up, effectively prevent the slippage with bus contact, guaranteed the reliability of busbar grounding.
3, standard the workflow of 10-35kV intermediate switchgear cabinet busbar grounding, eliminated because opening switch cubicle sealing chamber and destroyed bus insulation layer and recover again the extra consumption producing, reduced maintenance cost.
4, earth bus overall structure is comprised of insulated handle and the earth connection inserted sleeve that is arranged on insulated handle end, simple in structure, easy to operate, can meet the requirement of insulation and mechanical performance, and can operate outward at switch cubicle, is easy to popularization.
5, the utility model adopts and car switch contact analog structure, is easy to batch production and produces, and outward appearance is exquisite, firm in structure, can meet all kinds of environmental requirements of going out to carry in scene.
