Description
Technical field
The utility model belongs to field of electrical equipment, specifically a kind of switchgear Rapid grounding device.
Background technique
With the rapid development of social economy, in our Working Life, electric power resource plays an important role.Electricity
For power while bringing convenience to us, we should pay close attention to Electrical Safety.Switchgear is to convert low-voltage for high voltage pressure
Equipment, we only protect it and overhaul, and could ensure the safe handling people of electric power to electricity needs increasingly
Greatly, electric power plays a crucial role in people's lives, production process.However, power industry development in China's exists not
Few problem, is easy to bring some security risks, so being accounted for electricity consumption peace while we facilitate expecting that electric power is brought
Full problem.High and low voltage switchgear is mainly responsible for high voltage being changed into low-voltage, is finally sent to each unit, the equipment conduct
One pivotal player of power domain, carries extremely important task, so must attract people's attention, it be periodically to this
Equipment is checked, is repaired, and is guaranteed that substation, power supply company normally can dispense electric power for resident, is ensured that people produce life
The stabilization being normally carried out with society living.Switchgear must have reliable ground connection during maintenance, just can guarantee maintenance people
The personal safety of member, the safe and efficient operation of pre- counnter attack power transmission and whole system, before this, switchgear maintenance is unfolded in we
When work, usually guarantee the ground connection of switchgear using grounding trolley and earthing switch, but both earthing modes are out
Close cabinet most basic grounding requirement, will appear often grounding trolley ground connection it is not firm, earthing switch often occurs in division
Phenomena such as mechanical connecting lever clamping stagnation, thus in addition service personnel generally can carry additionally again ground line after switchgear power failure operation again
It is incorporated to grounded screen, but can be because the disunity of earthing clamp causes hanging earthing conductor difficult or ground line is hung when carrying additionally ground line
Incessantly phenomena such as.
Summary of the invention
A kind of switchgear rapid grounding dress is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art
Set, effectively solve switchgear carried additionally in maintenance process occur when ground line lose control of one's feelings or be grounded illusive phenomenon.
The technical solution of the utility model is: the switching copper bar including L-type, and the vertical plane for copper bar of transferring is equipped with a use
In setting in the first through hole connected with the copper bar of outlet mounting cable in switchgear, the horizontal plane for copper bar of transferring, there are two use respectively
In the second through-hole, the third through-hole that are fixedly connected with the first copper casting, the second copper casting;First copper casting is inverted L
Type, the horizontal plane of the first copper casting are placed in below the horizontal plane of switching copper bar, and the first copper casting is equipped with and matches with the second through-hole
Through-hole, the vertical plane of the first copper casting is equipped with fourth hole;Second copper casting and the first copper casting shape, size phase
Together, the second copper casting is opposite with the first copper casting and set;Copper rod screw rod is fixed on the first copper casting and second by fourth hole
Between copper casting.
The length of the copper rod screw rod is greater than the spacing between the first copper casting and the second copper casting.
The utility model beneficial effect is: it is easy for installation simple, it is easily assembled, is able to achieve the batch production of batch production,
It can be customized according to the different specification of switchgear inner copper line.No matter using spiral earth brace or double tongue compression types when maintenance
Earth brace very easily ground line can be hung up.
Detailed description of the invention
Fig. 1 is one of structural schematic diagram of the utility model.
Fig. 2 is the second structural representation of the utility model.
Fig. 3 is the usage state diagram of the utility model.
In figure, 1, switching copper bar, the 2, first copper casting, the 3, second copper casting, 4, copper rod screw rod, 5, pressure spring clamp, 6, the
One through-hole, the 7, second through-hole, 8, third through-hole, 9, fourth hole.
Specific embodiment
Fig. 1, in 2, a kind of switchgear Rapid grounding device includes the switching copper bar 1 of L-type, is transferred on the vertical plane of copper bar 1
Equipped with one for and in switchgear outlet mounting cable the first through hole 6 that connects of copper bar, set on the horizontal plane of switching copper bar 1
There are two be respectively used to the second through-hole 7, the third through-hole 8 that are fixedly connected with the first copper casting 2, the second copper casting 3.First casting in bronze
Part 2 is inverted L-type, and the horizontal plane of the first copper casting 2 is placed in below the horizontal plane of switching copper bar 1.First copper casting 2 is equipped with
Fourth hole 9 is equipped with the vertical plane of the matched through-hole of the second through-hole 7, the first copper casting 2.Second copper casting 3 and the first bronze medal
2 shape of casting, size are identical.Second copper casting 3 is opposite with the first copper casting 2 and sets.Copper rod screw rod 4 is solid by fourth hole 9
It is scheduled between the first copper casting 2 and the second copper casting 3.The length of the copper rod screw rod 4 is greater than the first copper casting 2 and the second casting in bronze
Spacing between part 3.
In Fig. 3, the utility model is fixed on the three-phase outlet copper bar of switchgear, in this way when switchgear overhauls
When using double tongue compression type earth braces, directly double tongue compression type earth braces are directly hung on copper rod screw rod 4, double tongue compression types connect
Pressure spring clamp 5 in the thin end of the scroll is engaged on copper rod screw rod 4, that is, completes ground connection work, convenient and efficient, not easily to fall off and can guarantee
The contact surface of earth brace and this device meets national standard, nor affects on the mounting of cable.It, can also according to spiral earth brace
Spiral earth brace is directly tightened on switching copper bar 1.It is previous using double tongue compression type earth braces, ground terminal be circular arc type with
The very inconvenient connection of rectangular copper bar linking, and be easy to fall off, after installing the utility model additional on the face of rectangular copper bar now,
So that being directed towards the direction of mounting earth brace with cylindrical copper rod screw rod 4.
