Description
Technical field
The utility model is related to a kind of technical fields of high voltage electric equipment, mutual more particularly to a kind of contact case type voltage
Sensor.
Background technology
Contact box is epoxy resin APG operation pressure gel forming structures, for various handcart switch cabinets, for contact
Installation and insulating protection component, including an inner cavity, the insulating body of intracavity bottom is embedded with the front and rear conductor penetrated through, leads
Body rear and front end is exposed, is respectively intended to connection contact and busbar.It usually there is provision of independent voltage transformer in switchgear,
Voltage transformer is installed with insulator, arrester cooperation, and the space occupied is larger, and difficulty is brought to the miniaturization of switchgear.
With the continuous development of China's switchgear industry, gradually to the miniaturization of switchgear, modularization, functionalization and peace
Dress such as facilitates to improve requirement at the performances, and therefore, switchgear industry especially needs a kind of collecting voltage mutual inductor, arrester, contact box etc.
The modular integrated product that element is integrated.
Invention content
The purpose of this utility model is to provide a kind of compact-sized contact case type voltage transformers.
To achieve the above object, the technical solution of the utility model is：
The utility model is a kind of contact case type voltage transformer, including contact box, mutual inductor ontology, voltage transformer,
High-voltage contact, outlet terminal A, flexible circuit conductor, an arrester；The contact box is integrated component with mutual inductor ontology,
Contact box is arranged on the top of mutual inductor ontology；High-voltage contact is mounted on the front end of mutual inductor ontology, a high-voltage contact
It is fixed threadably with the mutual inductor insulating cylinder of mutual inductor ontology by being embedded in the big nut of inner ring, a sub-high pressure touches
Head is connect with an outlet terminal A with flexible circuit conductor, to ensure that two outlet terminals are in same current potential, an outlet terminal A installation
In contact box, contact box is connect with arrester, and arrester is mounted in vertical direction in contact box.
The voltage transformer includes c-type iron core, mutual inductor coil；The mutual inductor coil is wound on mutual inductor C
On shaped iron core.
An outlet terminal A in the contact box is connected with screwed inserts, this inserts passes through with arrester
Screw mode is connect with the copper bar on arrester.
After using the above scheme, the utility model has the following advantages：
1st, since the utility model is an integral structure, contact box, arrester and voltage transformer is integrated, effectively dropped
Low switchgear uses space, while a leading-out terminal is directly connect with earthing switch, reduces copper bar coupling part
And material cost, make device in switchgear compacter, reduce occupied space, be conducive to the miniaturization of switchgear, reduce
The cost of switchgear device can be widely applied in the switchgear of electric system.
2nd, since the utility model is while the connection for realizing arrester and outlet terminal A of voltage transformer, again
Save the insulator being used to support and increase creepage distance accessed when arrester is connect with contact in previous scheme, while this
Kind scheme also relieves the space limitation of the top of a high-voltage contact of the voltage transformer in PT hand car.3rd, by
In the utility model by Products integration so that installation maintenance is more convenient.
In conclusion the utility model overcome component of the prior art it is more, it is complicated, safeguard it is cumbersome for installation, into
This height, bulky defect, so as to provide the band contact case type electricity that a kind of collecting voltage mutual inductor, arrester, contact box are integrated
Press mutual inductor.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Description of the drawings
Fig. 1 is the axonometric drawing of the utility model；

The contact box 1 is integrated component with mutual inductor ontology 2, and contact box 1 is arranged on the right side top of mutual inductor ontology 2
End, contact box 1 and mutual inductor ontology 2 are used together with poured with epoxy resin；High-voltage contact 4 is mounted on mutual inductor
The mutual inductor insulating cylinder of the front end of ontology 2, a high-voltage contact 4 and mutual inductor ontology 2 is by being embedded in the big nut of inner ring with spiral shell
The mode of line connection is fixed, and a high-voltage contact 4 is connect with an outlet terminal A5 flexible circuit conductor 6, to ensure two leading-out terminals
Son is in same current potential, and one time outlet terminal A4 is mounted in contact box 1, and contact box 1 is connect with arrester 7, the connection used
Mode is：An outlet terminal A4 in contact box 1 is connected with screwed inserts, this inserts passes through screw with arrester 7
Mode is connect with the copper bar on arrester 7.The arrester 7 is mounted in vertical direction in contact box 1.
The voltage transformer 3 includes c-type iron core 31, mutual inductor coil 32.The mutual inductor coil 32 is wound on
On mutual inductor c-type iron core 31.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
