Product, reduces copper, iron, steel, the consumption of oil, reaches cost efficiency, the convenient purpose installed.
Current transformer volume is big in current measurement apparatus, adds the use of the materials such as transformer oil, steel；And it is internal
Multiple current transformers to need to assemble installation one by one complicated.
The content of the invention：
It is an object of the invention to provide a kind of transformer measurement apparatus, with solve existing measurement apparatus identical
Accurate lower volume is larger, install complicated technical problem.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of transformer measurement apparatus, including shell, are arranged on the fixation cushion block in shell, and the inner side of fixed cushion block is set
There is integrated poured current transformer, be provided with outer side for going out of drawing integrated poured Current Transformer Secondary outlet
Compression cushion block is provided with the top of line box, integrated poured current transformer, during working condition, the sleeve bottom of transformer is positioned at whole
Body pours into a mould the center of current transformer.
Further improve of the invention is that integrated poured current transformer includes support wood block filler and set from bottom to top
Several monomer current transformers on support wood block filler are put, and between support wood block filler and several monomer current transformers
Using poured with epoxy resin into an entirety, secondary outgoing line plate, Mei Gedan are provided with the outside of several monomer current transformers
The secondary outgoing line of body current transformer is connected on secondary outgoing line plate.
Further improve of the invention is that the quantity of monomer current transformer is 2-6.
Further improve of the invention is that several monomer current transformers are by measurement level current transformer and protected level
Current transformer is constituted.
Further improve of the invention is that the iron core of one of measurement level current transformer uses permalloy system
Into the unshakable in one's determination of protected level current transformer is made of silicon steel sheet, and the iron core of remaining measurement level current transformer uses silicon steel sheet
Or Superfine crystal material is made.
Further improve of the invention is that the secondary outgoing line of each monomer current transformer is connected to using annealed copper strand wire
On secondary outgoing line plate.
Further improve of the invention is that monomer current transformer includes iron core-closed and is wrapped on iron core-closed
Wire.
Further improve of the invention is that shell is cylindrical shape, and is made of steel plate.
Compared with prior art, the present invention at least has following technique effect：
Because measurement apparatus of the present invention uses integrated poured current transformer, unify the external diameter of all current transformers,
The process of fixed current transformer is simplified, and simplifies integral installation process (originally 2-6 monomer current transformer is one by one
Install, it is cast-in-place to form entirety, carry out once mounting).
Further, measurement level current transformer core is high using initial permeability, the low permalloy system of saturation magnetic induction
Into meeting, current transformer primary current is small, under the high requirement of measurement accuracy, greatly reduces the size of current transformer.
