Description
Technical field
The utility model relates to a kind of substation grounding devices.
Background technique
It can not be solved in substation on the high capacity rectangular horizontal bus row (copper bar, aluminium row) with insulating sheath at present
The problem of hanging ground wire；When especially encountering maintenance main transformer, needs in main transformer two sides while installing earthing or grounding means,
Main transformer low-pressure side rectangle large capacity dielectric level bus, causes that ground connection can not be installed, reason is mostly: the low-pressure side of main transformer by
Design very big in electric current, that bus mostly uses rectangular bus bar to arrange, does not have Special grounding equipment, not small fiber crops is brought when to overhaul of the equipments
It is tired, the design of original ground line be much for linking round bus, it is often helpless for rectangular bus bar, and by force
The case where using (lateral suspension) that bus insulation can be destroyed when installing ground line, and be easy to fall off, to the safety of service work
Bring great hidden danger；The ground line of non-dedicated bus bar formula is used in many cases, it is not easy to operate.
If encountering main transformer maintenance at present to need to mostly use following methods when main transformer low-pressure side hangs ground wire:
1. having a spring clip using the ground line of non-dedicated rectangular bus bar, at the top of this ground line, under ground line
There is a pull rod in portion, when in use can in bottom, manually strength is pulled open, will ground line top be inserted laterally into nonisulated bus
In row, the spring potential energy of itself is then utilized, upper and lower two panels contact chip is pressed on bus bar, has reached and compresses bus and mother
The purpose of line row's ground connection.The defect of this design itself is, the intermediate draw bar of insulated pull rod is grounded, since its top is straight
Contact buses are connect, there are certain security risks, and are not easy to hang.Nowadays the outside of all bus bars is non-exposed mother
Line row in order to promote dielectric level and grade between bus between phase line and phase line, while being also easy for distinguishing separate, use mostly
Insulating sheath with phase colour code will, the design method for being so somebody's turn to do " non-dedicated rectangular bus bar ground line " is unable to satisfy and bus bar
Reliable contacts.
2. second is that the top opening of ground line is stuck in and is connect with low-voltage bus bar row end using common round busbar grounding line
Arrester connecting line on, since arrester upper end lead is relatively thin, the mechanical strength connecting with arrester is low, easily causes
The breakage of the connecting line, is reliably connected so that arrester cannot keep with bus, it is also possible to damage arrester, while the position is more
Farther out, the security risk threat generated when to maintenance is larger, and such ground connection is simultaneously in half-distance main transformer (service work) place
Unreliable, the quality of the multiply annealed copper wire of ground line is very big, and the connecting line of link bus row and arrester is difficult to bear so big
Weight, be easy to break tiny lightning conducter, to safety in production operation have very big threat.
Utility model content
Purpose of the utility model is to solve main transformer of transformer substation maintenance when, main transformer rectangular dielectric bus bar without
The problem of method reliable hanging earthing conductor, propose a kind of substation's horizontal rectangular bus bar earthing or grounding means.
A kind of substation's horizontal rectangular bus bar earthing or grounding means described in the utility model include metal master, connector,
Grounding head, two metal bayonet locks, ground line, fixing bolt, bayonet lock clamp and pull rod；
The metal master is bell-jar, and the upper end is equipped with bolt hole, and lower end is equipped with connection body opening, connects the hole of body opening
Wall is equipped with limiting slot；
Fixing bolt mutually agrees with after from top to bottom passing through isolated bus row with bolt hole；
The connector be it is cylindric, the side wall of connector is equipped with spacer pin, also, slides into limiting slot by spacer pin
Bottom complete connector with connect agreeing with for body opening；；
The bottom surface of connector is fixed on the top end of grounding head；
One end of ground line is connected on the side wall of grounding head；
Two metal bayonet locks are separately fixed on the side wall of grounding head lower end；
The bottom end of the bayonet lock clamp is fixed on the top of pull rod, and half drum card slot is equipped on bayonet lock clamp, should be partly
Drum card slot mutually agrees with two metal bayonet locks；
The bottom end of the pull rod is handheld terminal.
After by fixing bolt the rational position of isolated bus row is arranged in metal master by the utility model, pass through rotation
The handheld terminal of pull rod, since the bottom end of bayonet lock clamp is fixed on the top of pull rod, bayonet lock clamp and pull rod unitary rotation,
Half drum card slot of bayonet lock clamp is stuck on two metal bayonet locks of earthing or grounding means, and bayonet lock clamp drive afterwards is fixed with connector
Grounding head rotation, when connector close to metal master lower end be equipped with connection body opening when, pass through spacer pin slide into limit trench bottom
Complete connector with connect agreeing with for body opening, that is, complete ground line docked with what isolated bus was arranged, realization isolated bus arrange can
By hanging earthing conductor.
The utility model has the beneficial effects that provide it is a kind of simple and efficient, securely and reliably, hanging ground-wire side beautiful and generous
Formula does not cause other influences to power equipment and facility, and dismounts simple, and when dismounting, which need to only rotate 180 °, can be completed.
