Description
Technical field
The present invention relates to a kind of production methods of Open Type Electric Current Mutual Inductor.
Background technology
Open Type Electric Current Mutual Inductor, one of critical elements mating as electrical equipment, mainly give measuring instrument, instrument or
Protective device transmits information.Open Type Electric Current Mutual Inductor includes iron core and secondary winding, and iron core, which includes two, can be mutually butted shape
At the first iron core and the second iron core of closed magnetic circuit, two iron cores be c-type and thereon uniform coiling secondary winding and form line
Then circle, two coils make two semicircular line coil assemblies again with high-quality poured with epoxy resin at semicircular coil block
One end open, other end moveable hinge ground connection link together, and when installation only needs to be stuck in mutual inductor by open end to wait for
It will make mutual inductor banding in equipment to be connected by the fastening to opening again in connection equipment, installation is extremely convenient.
Since commercially available coil winding machine can only carry out coil winding to closed annular core or square core, and cannot be half-and-half
Cricoid non-close iron core carries out coiling, so existing Open Type Electric Current Mutual Inductor is in coiling secondary winding on iron core
Coiling is carried out using manual mode, manual coiling, can also be because of people not there is only the big problem of low production efficiency, labor intensity
Cause D.C. resistance, the excitation property of the coil of same batch same specification different for factor, so by two coil blocks
The quality of the current transformer of finished product can be impacted when connecting into a complete mutual inductor.
Invention content
The purpose of the present invention is to provide a kind of open-type electric current that can carry out winding technique to iron core on coil winding machine is mutual
The production method of sensor.
To achieve the above object, the technical solution of the production method of Open Type Electric Current Mutual Inductor of the present invention is：
The production method of Open Type Electric Current Mutual Inductor, includes the following steps, the first step, first by the first iron core and the second iron core
Fixation, which is docked, using fixing device circularizes entirety；Annular is integrally placed at the coiling that winding is carried out on coil winding machine by second step；The
The first iron core for being wound with winding and the second iron core are separated and individually carry out subsequent operation by three steps.
In the first step, the fixing device includes fixing sleeve, and the both ends of fixing sleeve are equipped with for the first iron core and the
The first cavity that the respective end of two iron cores stretches into, the second cavity.
First cavity is curvature and the compatible arc-shaped cavity of corresponding iron core curvature to the second cavity.
First cavity is connected with the second cavity.
The external surface shape of the fixing sleeve is in compatible arc with corresponding iron core curvature.
The fixing device is made of insulating materials.
The beneficial effects of the invention are as follows：First iron core is docked fixed cyclization by the present invention using fixing device with the second iron core
Shape is whole, and annular entirety can be positioned over the coiling that winding is carried out on coil winding machine, again by coil by fixing dress after coiling
Taking-up is set to pour into a mould again.It not only increases the production efficiency of winding technique, reduce worker labourer's intensity, also help realization
The internal mass standards of product.

The specific embodiment of the production method of the Open Type Electric Current Mutual Inductor of the present invention, as shown in Figure 1 to Figure 3, including with
Lower step：
The first step, first passes through fixing device and docks the first iron core with the second iron core and be fixed into the annular with closed magnetic circuit
It is whole；
In the first step, the first iron core 1 and the second iron core 2 are in semi-circular, not influence magnetic circuit in iron core, fixing sleeve 3
It is made of insulating board, shape is subject to 2 size of practical iron core, can play fixed function with by the first iron core 1 and the second iron core 2
It is closed integral ring-shaped that docking is fixed into a head and the tail.In the present embodiment, fixing sleeve 3 has the inner cavity 31 of arc, interior
Chamber 31 is in the radian arc consistent with the radian of the first iron core 1 in the lateral direction, and the both ends of fixing sleeve 3 are respectively equipped with and inner cavity
31 communicate so that the respective end of the first iron core 1 and the second iron core 2 is open by first that it extend into inner cavity, second is open.
It is as follows in the first step：The first opening of two fixing devices is first set in the first iron core 1
Depth is inserted in be advisable between two parties in both ends.Then, 2 both ends of the second iron core are inserted into the second opening of two fixing devices together
In, so that the first iron core 1 and the second iron core 3 are combined into the closed annular entirety of head and the tail.
Annular entirety is put into the coiling for carrying out winding on loop wire winder by normal winding mode by second step；
Third walks, and after coiling finishes, two half-coils are taken out from fixing device；
4th step, pours into coil after coil block again that the hinged, other end is opened by two coil block one end respectively
Mouth ground connects and current type mutual inductor is made.
In other embodiments, insulating board by other insulating materials or can be also made of an electrically conducting material；For limitation
Iron core sleeve is fitted into the depth in fixing sleeve, can also be arranged in the inner cavity of fixing sleeve by inner cavity be separated into respectively with first opening
First cavity of connection and the partition board with the second cavity of the second open communication；Certainly, fixing device can also be had and iron
The clamping stirrup in the compatible clamping face of core respective side shape, can destroying gluing etc., other can realize the first iron core and the second iron
The fixing device that core is fixedly connected replaces.
