Abstract
The utility model discloses a kind of bus-bar earthing wire clamp, coated insulation on busbar, the problem of working earthing lines can not be installed are solved.Conductive contact plate and grounding connection frame are specifically included, the conductive contact plate is bolted to connection with bus bar, and contact surface therebetween is smooth flat；The grounding connection frame, including two perpendicular band irons and a horizontal band iron, two of which erect the centre that band iron is respectively welded at two parallel edges of conductive contact plate, and the top welding of band irons is erected on the both sides of horizontal band iron with two respectively.The bus-bar earthing wire clamp, operations staff installs ground wire conveniently, and favorable comment has been obtained in practice.
Description
Technical field
The utility model is related to a kind of appurtenance for overhauling and being used when power transformer or armoured switch cabinet.
Background technology
Low-tension side of power transformer bus and armoured switch cabinet bus are all by copper bus-bar or aluminium bus array group in power system
Into, in order to ensure electric power netting safe running, need on busbar coated insulation, so when maintenance power transformer or armoured switch cabinet
When, working earthing lines can not be installed, the life security of serious threat maintainer.
The content of the invention
The purpose of this utility model is to provide a kind of bus-bar earthing wire clamp, during maintenance, and working earthing lines pass through the ground wire
Folder is installed, it is ensured that the safety of staff.
For achieving the above object, the technical solution adopted in the utility model is：A kind of bus-bar earthing wire clamp, including lead
Electrical Contact Plate and grounding connection frame, the conductive contact plate are square aluminium alloy plate or copper coin, its specification and be connected bus
The specification of row is identical, and some bolt connecting holes are set on conductive contact plate, and above-mentioned bolt connecting hole is connected on bus bar with required
Some eyelets set are corresponded, and conductive contact plate is bolted to connection with bus bar, and contact surface therebetween
For smooth flat.
The grounding connection frame, including two perpendicular band irons and a horizontal band iron, perpendicular band iron are identical with the width of horizontal band iron, horizontal
The length of band iron is equal with the length of side of conductive contact plate, and the material for erecting band iron and horizontal band iron is identical with conductive contact plate, wherein two
Bar erects the centre that band iron is respectively welded at two parallel edges of conductive contact plate, the tops of the both sides of horizontal band iron respectively with two perpendicular band irons
End welding.
The beneficial effects of the utility model：The bus-bar earthing wire clamp of the application, installs simple, operations staff installs ground wire
It is convenient, favorable comment has been obtained in practice.
Brief description of the drawings
Fig. 1 is the main sectional view of the utility model bus-bar earthing wire clamp.
Fig. 2 is Fig. 1 top view.
Fig. 3 is Fig. 1 side view.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1 combinations Fig. 2, Fig. 3：A kind of bus-bar earthing wire clamp, including conductive contact plate 1 and grounding connection frame, institute
It is square aluminium alloy plate or copper coin to state conductive contact plate 1, and its specification is identical with the specification of connected bus bar, conductive contact plate
Some bolt connecting holes are set on 1, and above-mentioned bolt connecting hole is corresponded with some eyelets set on required connection bus bar,
Conductive contact plate 1 is bolted to connection with bus bar, and contact surface therebetween is smooth flat.
The grounding connection frame, including two perpendicular band irons 2 and a horizontal band iron 3, erect the width phase of band iron 2 and horizontal band iron 3
Together, the length of horizontal band iron 3 is equal with the length of side of conductive contact plate 1, erects the material and the phase of conductive contact plate 1 of band iron 2 and horizontal band iron 3
Together, two of which erects the centre that band iron 2 is respectively welded at two parallel edges of conductive contact plate 1, the both sides of horizontal band iron 3 respectively with
The top welding of two perpendicular band irons 2.
In use, needing to stamp adaptation at ground connection in low-tension side of power transformer or armoured switch cabinet bus bar first
Four eyelets, then corresponding four bolt connections are also stamped on the conductive contact surfaces of bus-bar earthing wire clamp, to bus bar and mother
The contact surface of row's earthing clamp is handled, and makes surface smooth, reduces contact resistance, then carried out tightly with corresponding four bolts
Gu, then earth lead is connected on grounding connection frame, it is ensured that the peace at the grounding connection end of the bus-bar earthing wire clamp after fastening
Row distance for the national games, is also convenient for the operation of operations staff.
