Description
Technical field
The utility model relates to a kind of instrument transformer, particularly relates to a kind of open-close type current transformer.
Background technology
In the circuit of generating, power transformation, transmission of electricity, distribution and electricity consumption, size of current great disparity, has from a few peace to a little Wan An.For ease of measurement, protect and control to need to be converted to more unified electric current, the voltage in addition on circuit generally all higher as direct measurement is breakneck.Current transformer just plays current transformation and electrical isolation effect.Current transformer principle is according to electromagnetic induction principle.Current transformer is made up of the iron core closed and winding.Its umber of turn is little; go here and there in the circuit needing the electric current measured; therefore it often has whole electric currents of circuit to flow through; secondary winding turn ratio is more; be serially connected in measuring instrument and protective loop, operationally, its 2 minor loops are closed to current transformer all the time; therefore the impedance of measuring instrument and protective loop series coil is very little, and the operating state of current transformer is close to short circuit.Closed iron core and winding composition working component, arrange in the enclosure, the shell of traditional current transformer is connected by multiple bolt or screw, if after damage appears in internal work component, it is changed, needs to open shell again, complicated operation by after all bolts or screw dismounting.
Utility model content
The purpose of this utility model is just to provide a kind of open-close type current transformer to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of open-close type current transformer, comprise shell and working component, described working component is arranged in described shell, described shell comprises upper half shell and lower half shell, described upper half shell and described lower half shell include protecgulum and bonnet, the first end of described upper half shell and the first end of described lower half shell are rotatably connected by rotating axis, second end of described upper half shell is provided with upper junction plate, second end of described lower half shell is provided with lower connecting plate, described upper junction plate and described lower connecting plate are provided with through hole, the connecting bolt for connecting described upper junction plate and described lower connecting plate is provided with in described through hole.
Further, described current transformer also comprises fixed head, the two ends of described fixed head are provided with circular hole, the same side panel of described upper junction plate and described lower connecting plate are respectively arranged with two fixed legs, and two circular holes of described fixed head are set on two described fixed legs.
Particularly, the top of described fixed leg is provided with external screw thread, described fixed head and the nut fixed position of described fixed leg by engaging with described external screw thread.
Particularly, described upper half shell and described lower half shell are two rectangular enclosure that volume is equal, and described rotation axis, described upper junction plate and described lower connecting plate are all arranged on the contact-making surface place of described upper half shell or described lower half shell.
The beneficial effects of the utility model are:
The upper half shell of the utility model open-close type current transformer is connected by rotating axis with the first end of lower half shell, second end is fixed by connecting bolt, make it when using, only need to fix the assembling that namely the second end can realize shell, if need to change working component, then only need the connecting bolt of dismounting second end, namely upper half shell can be rotated, realize the replacing to working component.
Accompanying drawing explanation
Fig. 1 is the exploded view of open-close type current transformer described in the utility model;

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of open-close type current transformer, comprise shell, working component 3 and fixed head 9, working component 3 arranges in the enclosure, shell comprises upper half shell 1 and lower half shell 2, upper half shell 1 and lower half shell 2 include protecgulum and bonnet, the first end of upper half shell 1 and the first end of lower half shell 2 are rotatably connected by rotating axis, second end of upper half shell 1 is provided with upper junction plate 5, second end of lower half shell 2 is provided with lower connecting plate 6, upper junction plate 5 and lower connecting plate 6 are provided with through hole, the connecting bolt 7 for connecting upper junction plate 5 and lower connecting plate 6 is provided with in through hole, the two ends of fixed head 9 are provided with circular hole, the same side panel of upper junction plate 5 and lower connecting plate 6 is respectively arranged with two fixed legs 8, two circular holes of fixed head 9 are set on two fixed legs 8, the top of fixed leg 8 is provided with external screw thread, fixed head 9 and the nut fixed position of fixed leg 8 by engaging with external screw thread, upper half shell 1 and lower half shell 2 are two rectangular enclosure that volume is equal, rotate axis 10, upper junction plate 5 and lower connecting plate 6 are all arranged on the contact-making surface place of upper half shell 1 or lower half shell 2.
The operation principle of the utility model open-close type current transformer is as follows:
When operation of current transformers, connecting bolt 7 is inserted in the through hole of upper junction plate 5 and lower connecting plate 6, then screwed, fixing upper half shell 1 and lower half shell 2, on fixed head 9 two circular hole is inserted on the fixed leg 8 on upper half shell 1 and lower half shell 2 simultaneously, again nut is screwed in fixed leg 8, by connecting plate and joint pin, secondary is realized to upper half shell 1 and lower half shell 2 and fix, avoid it to occur loosening; Internal work component 3 break down need to repair or replace time, only need nut, fixed head 9 and connecting bolt 7 to take off successively, then upper half shell 1 or lower half shell 2 rotated along its first end, then shell is opened.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection range of the present utility model.
