Description
Technical field
This utility model is related to transformer technical field, more specifically, particularly to a kind of current transformer.
Background technology
Current transformer is the most key infrastructure device in power system, plays measurement and protective effect, is used to survey
The device of size of current in amount circuit.When the electric current in a certain circuit is too large to by instrument direct measurement out,
At this moment the opposite side of current transformer can produce proportional small current exactly in circuit, thus can facilitate and directly use
Apparatus measures simultaneously record.Current transformer can completely cut off the high voltage being likely to occur in circuit under test simultaneously, so that protection
Instrument.
When straight-through current transformer is installed, there is certain deviation due to processing in existing bus-bar, but existing
Technology easily occurs rocking or installation deviation by the way of screw is directly fixed.For this reason, it is necessary to design a kind of improved electricity
Current transformer.
Utility model content
The purpose of this utility model is to provide the current transformer that a kind of structure is simple, easy for installation and error is little.
In order to achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of current transformer, including straight-through current transformer body and on straight-through current transformer body
Opening, is provided with least two bus-bars, is provided with insulation board, positioned at the remittance of both sides between two adjacent bus-bars in described opening
Stream row be connected with straight-through current transformer body by one group of elastic fastening device respectively, and described elastic fastening device includes L
Fixing piece of shape, rubber cushion cover and plastics trip bolt, one end of fixing piece of described L-shaped is fixed on centre path current mutual inductance
On device body, the other end of fixing piece of described L-shaped is provided with fixing hole, and described plastics trip bolt sequentially passes through fixing hole, rubber
Connect with corresponding bus-bar after glue cushion collar.
Further, one end of fixing piece of described L-shaped is fixed on straight-through current transformer originally by way of welding
On body.
Further, it is additionally provided with pad between described rubber cushion cover and bus-bar.
Further, the bus-bar positioned at both sides passes through two groups of elastic fastening devices with straight-through current transformer originally respectively
Two end faces of body connect.
Compared with prior art, the utility model has the advantage of：Due to employing, L-shaped is fixing to prop up piece to this utility model,
When mounted certain amount of elasticity is had according to the tightness of trip bolt, integrally there is structure simple, easy for installation and by mistake
The little advantage of difference.

Define.
Refering to shown in Fig. 1, this utility model provides a kind of current transformer, including straight-through current transformer body 1 and
Opening 2 on straight-through current transformer body 1, is provided with least two bus-bars in described opening 2, adjacent two are converged
It is provided with insulation board 4, the bus-bar positioned at both sides passes through one group of elastic fastening device and centre path current mutual inductance respectively between stream row
Device body 1 connects, and described elastic fastening device includes fixing piece 6 of L-shaped, rubber cushion cover 7 and plastics trip bolt 9, described L
One end of fixing piece 6 of shape is fixed on straight-through current transformer body 1, and the other end of fixing piece 6 of described L-shaped is provided with admittedly
Determine hole, described plastics trip bolt 9 is sequentially passed through fixing hole, connected with corresponding bus-bar after rubber cushion cover 7.
Preferably, one end of fixing piece 6 of described L-shaped is fixed on straight-through current transformer originally by way of welding
On body 1.
Preferably, being additionally provided with pad 8 between described rubber cushion cover 7 and bus-bar.
Design principle of the present utility model is：When mounted, the end face corresponding positions of present straight-through current transformer body 1
Put fixing piece 6 of welding L-shaped, it is fixing that plastics trip bolt 9, rubber cushion cover 7 and pad 8 are passed through in the fixing end propping up piece 6 of L-shaped
On the busbar, because the fixing piece 6 of L-shaped adopts metal material, when mounted, have one according to the tightness of trip bolt
Fixed amount of elasticity, can make easier for installation.
Preferably, the bus-bar being located at both sides passes through two groups of elastic fastening devices with straight-through current transformer originally respectively
Two end faces of body 1 connect, and because both sides are all connected by elastic fastening device, mounting structure can be made more stable.
Preferably, adopting two bus-bars in the present embodiment, i.e. the first bus-bar 3 and the second bus-bar 5,
Although being described in conjunction with the accompanying embodiment of the present utility model, patent owner can want in appended right
