Description
Technical field
The utility model is related to a kind of voltage transformer that can be used with the common car of arrester.
Background technology
Handcart need to be only changed when handcart switch cabinet is due to maintenance, therefore maintenance power off time can be shortened, it is adaptable to load
The less place of more important or construction area, provided with elements such as breaker, transformer, transformer, arresters in cabinet.Voltage
The primary side of transformer and the high-pressure side of transformer should be equipped with arrester.
The mounting means of arrester 10 and voltage transformer 20 is as shown in figure 1, arrester 10 in current handcart switch cabinet
Earth terminal electricity be directly connected on the metal shell 30 of handcart switch cabinet, the other end of arrester 10 then pass through copper bar 40 with it is electric
The touching electrical connection of fuse contact 501 on transformer contact arm 50 is pressed, because copper bar 40 with contact 501 and arrester 10 has dry
Relate to, therefore once the fuse in contact arm 50 need to be changed（Not shown in figure）, then when that will dismantle before contact 501, need
Copper bar 40 is first removed or disassembled, is bothered very much.
In consideration of it, the present inventor develops a kind of voltage transformer that can be used with the common car of arrester, effective solution for this
Determine above mentioned problem, thus this case produces.
Utility model content
A kind of voltage transformer that can be used with the common car of arrester that the utility model is provided, it is simple in construction, it can accomplish to melt
The independence of disconnected device and arrester installing/dismounting, it is convenient to install and maintain.
To achieve these goals, the technical solution of the utility model is as follows：
It is a kind of can with the arrester voltage transformer that use of car altogether, including contact arm, fuse, fuse contact, nut and
Lug plate, contact arm outer end opening, nut is embedded to be installed on the outer end opening, and fuse is put into contact arm at nut, fuse
Contact opens up external screw thread, and fuse contact is tightened and electrically connected in the nut after fuse, and lug plate is fixed with nut,
Lug plate stretches out contact arm, and lug plate is used for and arrester is electrically connected and installed.
Form screwed hole on the lug plate, screwed hole is used to install with connecting ear and soft led with what arrester was electrically connected
Line.
The outer circumference surface of the nut opens up groove, and lug plate is embedded to be installed in the groove.
After such scheme, the utility model is directly electrically connected no longer by arrester with fuse contact touching, but
By additionally mounted lug plate on the nut at contact arm outer end opening, it is electrically connected by the lug plate and arrester of simple structure
Connect, in replacing fuse without dismounting or the part of mobile arrester, and equally melted when changing arrester without dismounting
Disconnected device contact, accomplishes the independence of fuse and arrester installing/dismounting.
Brief description of the drawings
The scheme of installation of Fig. 1 prior arts；
Fig. 2 is the structural representation of the present embodiment；
Fig. 3 is the structural representation of the present embodiment nut and lug plate；
Fig. 4 is the scheme of installation of the present embodiment.
Label declaration
Arrester 10, voltage transformer 20, metal shell 30, copper bar 40, contact arm 50, fuse contact 501；
Contact arm 1, fuse contact 2, nut 3, groove 31, lug plate 4, screwed hole 41, flexible circuit conductor 5, connecting ear 51, bolt
6, arrester 7.
Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row is elaborated.
As in Figure 2-4, it is that a kind of of the utility model announcement can be with the voltage transformer that car be used altogether of arrester 7, bag
Include contact arm 1, fuse（Common structure, not shown in figure）, fuse contact 2, nut 3 and lug plate 4, the outer end opening of contact arm 1,
Nut 3 is embedded to be installed on the outer end opening.During installation, fuse is put at nut 3 in contact arm 1, and fuse contact 2 opens up outer
Screw thread, fuse contact 2 is tightened and electrically connected in the nut 3 after fuse.
Lug plate 4 is fixed with nut 3, lug plate 4, which stretches out, forms screwed hole 41 on contact arm 1, lug plate 4.Such as Fig. 4 institutes
Show, screwed hole 41 is used to install flexible circuit conductor 5, and one end of flexible circuit conductor 5 has connecting ear 51, locked connecting ear 51 by bolt 6
On screwed hole 41, the installation of flexible circuit conductor 5 and lug plate 4 is completed, to facilitate the installation of flexible circuit conductor 5, the other end of flexible circuit conductor 5 is then
Arrester 7 is electrically connected to, by flexible circuit conductor existing copper bar can be avoided to touch the problem of electrical connection may cause loose contact.
The outer circumference surface of wherein nut 3 opens up groove 31, and lug plate 4 is embedded and is fixedly welded in the groove 31, therefore
Before nut 3 is installed, lug plate 4 and nut 3 first can be fixed on one.
After such scheme, the utility model no longer by arrester 7 directly and fuse contact 2 touch electrical connection, and
It is, by additionally mounted lug plate 4 on nut 3, to be electrically connected by lug plate 4 and arrester 7, it is simple in construction.Installing/dismounting fuses
During device, fuse contact 2 is outwarded winding, fuse is then taken in and out contact arm 1 at the hole of nut 3.Installing/dismounting arrester 7
When, the flexible circuit conductor 5 on lower lug plate 4 is directly dismantled, without dismantling fuse contact 2, therefore the utility model can be accomplished
The independence of fuse and the installing/dismounting of arrester 7.
Preferred embodiment of the present utility model is these are only, not to the restriction of protection domain of the present utility model.It is all according to
The equivalent variations that the mentality of designing of this case is done, each fall within the protection domain of this case.
