Description
Technical field
The utility model relates to a kind of power equipment, particularly a kind of power cable on line joint for power equipment.
Background technology
On-the-spot in electricity usage, as electric substation, need electric substation high-tension electricity access being exported low pressure, therefore, need high-tension bus-bar to be connected with the external wiring screw rod of electric substation.But because copper aluminium directly connects and can produce electrochemical reaction, increase contact resistance, burn joint, this problem can be avoided with copper-aluminium transition equipment cable clamp.Existing copper-aluminium transition wire clip, copper-aluminium transition wire clip as power transformer makes with single copper material or aluminium, it is the screw connector that wiring screw rod external with power equipment is connected and the clamping plate type connector entirety dimerous being connected outside aluminum steel, wherein the screw axis of screw connector is parallel with clamping plate type connector, the space not only taken is comparatively large, and due to by wiring space to affect fitting operation also not too convenient.In addition, the wire clamp that this homogenous material is made, its conduction reliability is also not ideal.Aluminum clamping plate type connector once connected together with screw connector by the method for twice casting by someone, but cannot use because intensity is too poor eventually.
Utility model content
In view of this, be necessary to provide a kind of easy-to-connect, and the power cable on line joint taking up room less, to overcome above-mentioned deficiency.
A kind of power cable on line joint, for connecting high pressure aluminum steel and copper screw rod.Described power cable on line joint comprises a screw rod sandwiched head, a support plate extended from the first end of described screw rod sandwiched, and an aluminum steel line ball joint arranging this support plate other end.Described support plate and screw rod sandwiched head are at an angle to make described aluminum steel line ball joint and the angle of screw rod sandwiched head between high pressure aluminum steel described when installing described high pressure aluminum steel and copper screw rod respectively and the axis of copper screw rod be between 20 degree to 70 degree.
Compared with prior art, support plate due to power cable on line joint of the present utility model puts down from screw rod to establish the bottom center of joint out downward-sloping, the angle stated between the axis of high pressure aluminum steel and copper screw rod is made to be between 20 degree to 70 degree, so not only reduce shared space, also increase operating space during installation simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
Fig. 1 is the decomposition texture schematic diagram of power cable on line joint provided by the utility model.
Fig. 2 is the sectional structure schematic diagram of the power cable on line joint of Fig. 1.
Embodiment
Based on accompanying drawing, specific embodiment of the utility model is further elaborated below.Should be appreciated that specific embodiment described herein is as just embodiment, and be not used in restriction protection range of the present utility model.
As Fig. 1, it is the decomposition texture schematic diagram of novel the provided a kind of power cable on line joint 100 of this enforcement.Described power cable on line joint 100 is for connecting high pressure aluminum steel 20 and copper screw rod 30.It is well known that described high pressure aluminum steel 20 is the electrical lead drawing in such as electric substation from high voltage transmission line.And copper screw rod 30 is the joint that electric substation is electrically connected with the external world, screw-rod structure is usually used conveniently to regulate with fixing, as regulated height.
Described power cable on line joint 100 comprises a screw rod sandwiched 10, from a described screw rod sandwiched support plate that 10 one end are extended 11, and an aluminum steel line ball joint 12 arranging this support plate 11 other end.
Described screw rod sandwiched 10 comprises the through hole 102 that a body 101, is opened in described body 101, and two journal stirrups 103 extended along the axis direction perpendicular to described through hole 102 from body 102.Described screw rod sandwiched 10 is made up of copper material.Described through hole 102 is for plugging copper screw rod 30, it is an open type through hole, namely on the sidewall of the through hole 102 of the side towards journal stirrup 103, an opening is offered, thus can work as when screwing tight two journal stirrups 103 with bolt, the diameter of through hole 102 is reduced, thus described copper screw rod 30 can be clamped.Therefore described two journal stirrups 103 offer a bolt hole 104 respectively.Described power cable on line joint 100 comprises a bolt 14 be located in described bolt hole 104 further.
Described support plate 11 extends out from one end centre of screw rod sandwiched 10, this support plate 11 and screw rod sandwiched 10 at an angle, even if when described aluminum steel line ball joint 13 and screw rod sandwiched 10 installs described high pressure aluminum steel 20 respectively with copper screw rod 30, the angle between described high pressure aluminum steel 20 and the axis of copper screw rod 30 is between 20 degree to 70 degree.Preferably, the angle between described high pressure aluminum steel 20 and the axis of copper screw rod 30 is between 30 degree to 45 degree.In the present embodiment, the angle between described high pressure aluminum steel 20 and the axis of copper screw rod 30 is 45 degree.Therefore the angle of described support plate 11 is between 110 degree to 160 degree, and in the present embodiment, the angle of described support plate 11 is 135 degree.Described support plate 11 is shaping with described screw rod sandwiched 10 integrated die-casting.
Described aluminum steel line ball joint 12 comprise a upper cover 121 and one and this upper cover 121 with the use of lower cover 122, and at least two impacted bolts 123.Described high pressure aluminum steel 20 is pressed between described upper cover 121 and lower cover 122, is then connected and fixed described high pressure aluminum steel 20 by described at least two impacted bolts 123.Described aluminum steel line ball joint 12 is welded together with support plate 11 by described lower cover 122, thus as a whole with screw rod sandwiched joint 10 one-tenth.In the present embodiment, described aluminum steel line ball joint 12 has 4 impacted bolts 123.
Described power cable on line joint 100 also comprises one and is arranged on the gusset 15 of described screw rod sandwiched between 10 and support plate 11.This gusset 15, for strengthening the intensity of screw rod sandwiched between 10 and support plate 11, prevents again high pressure aluminum steel 20 in swing process, makes the angle change of support plate 11 too greatly.
Compared with prior art, support plate due to power cable on line joint 100 of the present utility model puts down from screw rod to establish the bottom center of joint 10 out downward-sloping, the angle stated between the axis of high pressure aluminum steel 20 and copper screw rod 30 is made to be between 20 degree to 70 degree, so not only reduce shared space, also increase operating space during installation simultaneously.Screw rod sandwiched joint 10 of the present utility model adopts copper material and aluminium respectively with aluminum steel line ball joint 13 in addition, and holds together with welding manner, thus ensure that good electric conductivity.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do in spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection range of the present utility model.
