Abstract
The utility model discloses a grounding device dedicated to a switch cabinet bus. The grounding device comprises insulating rods and is characterized in that the top of each insulating rod is equipped with a contact cover, that the bottom of each insulating rod is equipped with an operating handle, that a contact finger and a spring are disposed in each contact cover, that each contact finger is arranged on the top of the corresponding spring and is connected with one end of a ground wire, that the other end of each ground wire is provided with a grounding bolt. The use of the grounding device greatly decreases difficulty and time in ground wire installation for operators so as to reduce the work strength of the operators on the previous basis.
Description
technical field:
The utility model relates to a kind of installation instrument of power transformation engineering, particularly relates to a kind of switch cabinet bus Special grounding device.
background technology:
In switch cubicle maintenance, for guaranteeing the safety of service work, often need to be by busbar grounding.Current switch cubicle equipment generally can install Special grounding cabinet additional on one section of bus, and dropping into bus ground cutter can be by busbar grounding.But in real work, bus ground cutter, because frequency of utilization is lower, often there will be problem.In order to guarantee the fail safe of maintenance, generally can on the switch cabinet bus of job site, do earth connection.Because traditional earth connection is not made for switch cubicle device structure is special, articulate difficulty so use traditional earth connection to cause, the unstable problem of ground connection, affects the fail safe of work.
In switch cubicle equipment, dolly part belongs to female contact, and bus belongs to public contact, make ground wire to bus, just ground wire need to be inserted to contact box, is then articulated on bus.For traditional earth connection, there are two problems: (1) connector box adopts concave structure, after earth connection inserts contact box, earth connection head becomes substantially parallel state with bus conductive rod, activity space is very little, earth connection head is difficult to clamp smoothly bus conductive rod, does safety measure brought very large inconvenience to operations staff.(2) because earth connection and conducting rod can not become 90 degree clamping connections, ground connection is insecure, and easily loosening uncoupling, has brought great potential safety hazard to service work.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, fail safe good, stability is high and reduce the switch cabinet bus Special grounding device of installing earth connection difficulty.
The technical solution of the utility model is: a kind of switch cabinet bus Special grounding device, contain insulating bar, the upper end of described insulating bar is provided with Contact Cover, the lower end of described insulating bar is provided with operating grip, in described Contact Cover, be provided with fingertip and spring, described fingertip is positioned at the upper end of described spring, and described fingertip is connected with the one end of connecting wires, and the other end of described earth connection is provided with earth stud.
Described fingertip is Y shape metal clips.Described Contact Cover is three, and the described fingertip in three described Contact Cover is connected with one end of described connecting line respectively.The two ends of described insulating bar are connected with described Contact Cover and operating grip respectively by screw thread.Described operating grip is the insulating sleeve with anti-slip tank, and this insulating sleeve is sleeved on the lower end of described insulating bar, and the two is tight fit.
The beneficial effects of the utility model are:
1, the utility model has reduced difficulty and time that operations staff installs earth connection greatly, thereby on original basis, has reduced operations staff's working strength.
2, the utility model Contact Cover and switch cabinet contact box are used in conjunction with, and make in insertion contact box that earthing device can be stable and keep, and in addition, spring makes fingertip contact well with conducting rod, guarantees enough pressure.
3, the utility model is simple in structure, stability is high and reduce installing earth connection difficulty, has greatly increased the fail safe in service work, and it is applied widely, is easy to promote, and has good economic benefit.
accompanying drawing explanation:
Fig. 1 is the structural representation of switch cabinet bus Special grounding device.
embodiment:
Embodiment: referring to Fig. 1, in figure, 1-fingertip, 2-spring, 3-Contact Cover, 4-insulating bar, 5-earth connection, 6-operating grip, 7-earth stud.
Switch cabinet bus Special grounding device contains insulating bar 4, wherein: the upper end of insulating bar 4 is provided with Contact Cover 3, the lower end of insulating bar 4 is provided with operating grip 6, in Contact Cover 3, be provided with fingertip 1 and spring 2, fingertip 1 is positioned at the upper end of spring 2, fingertip 1 is connected with 5 the one end of connecting wires, and the other end of earth connection 5 is provided with earth stud 7.
Fingertip 1 is Y shape metal clips.Contact Cover 3 is three, and the fingertip 1 in three Contact Cover 3 is connected with one end of connecting line 5 respectively.
The two ends of insulating bar 4 are connected with Contact Cover 3 and operating grip 6 respectively by screw thread, are convenient to dismounting.Or operating grip 6 is the insulating sleeve with anti-slip tank, this insulating sleeve is sleeved on the lower end of insulating bar 4, and the two is tight fit.
After the pull-out of switch cubicle car switch, first earth stud 7 is connected with equipment ground row, then bus contact box dividing plate is opened, staff's manipulation operations handle 6 inserts Contact Cover 3 along contact box, until bus conductive rod contacts with fingertip 1 well, now earthing device can remain self-holding, can complete ground connection work.
After having worked, staff only needs manipulation operations handle 6 that Contact Cover 3 is extracted from contact box, removes earth terminal.
