Abstract
The utility model discloses a folding type current transformer iron core. It is formed by two iron core unit butt joints. The iron core unit be by more than two, the same chip lamella of shape folds and pile forms. Its characteristics are the two sides of chip lamella has pit and arch respectively, the pit is the same with bellied shape and correspond. In two adjacent chip lamellas, protruding corresponding on pit on chip lamella proximal surface and another chip lamella proximal surface, and the arch on chip lamella proximal surface is in the corresponding pit on another chip lamella proximal surface of inseparable form card income. Adopt the current transformer of this kind of iron core, the output current precision is high, can realize carrying out the purpose protected to the motor. Be particularly useful for in the control and the current transformer in the protection switch circuit of motor.
Description
Technical field
This utility model relates to a kind of coil iron core.Specifically, it is the superposed type iron core used on current transformer, it is adaptable to during Motor Control switchs with protection.
Background technology
At present, the current transformer used in Motor Control with protection switch is all traditional product.The iron core used in this current transformer is that iron core unit therein is to be stacked by the chip lobe that many plate shapes are identical to form by iron core-closed the forming of two iron core unit docking.And be all to use screw bolt and nut to stack and fix together between the identical chip lobe of many plate shapes, thus form one and there is certain thickness described iron core unit.It is all to use screw bolt and nut to be fixed due to the connection between the chip lobe that many plate shapes are identical, the situation that loosens can occur between chip lobe when running into vibrations, thus cause the change of current transformer output electric current.Therefore, the output current precision using the current transformer of this iron core is the highest.Again owing to using screw bolt and nut to be fixed, it is given a shock between rear bolts and nuts and can loosen, so, also result in the change of current transformer output electric current, make the output current precision of current transformer reduce.Low due to the output current precision of current transformer again so that the electric current that Motor Control is detected with protection switch is inaccurate, it is difficult to realize the purpose that motor is protected.
Utility model content
Problem to be solved in the utility model is to provide a kind of superposed type current transformer core.Using the current transformer of this iron core, output current precision is high, can realize the purpose protecting motor.
The problems referred to above to be solved in the utility model are realized by techniques below scheme:
Superposed type current transformer core of the present utility model is formed by two iron core unit docking.Described iron core unit is to be stacked by two or more, chip lobe that shape is identical to form.Being characterized in that the two sides of described chip lobe has pit and projection respectively, described pit is identical and corresponding with protruding shape.In two adjacent chip lobes, in the pit on a chip lobe proximal surface is corresponding with the projection on another chip lobe proximal surface, and the projection on a chip lobe proximal surface is the respective dimple that tight shape snaps on another chip lobe proximal surface.
As can be seen from the above scheme, owing to the two sides of described chip lobe has pit and projection respectively, described pit is identical and corresponding with protruding shape.In two adjacent chip lobes, in the pit on a chip lobe proximal surface is corresponding with the projection on another chip lobe proximal surface, and the projection on a chip lobe proximal surface is the respective dimple that tight shape snaps on another chip lobe proximal surface.It is not required to use bolt and screw to achieve that stacking between multiple chip lobe, fixing, even if running into vibration, the situation that loosens also will not occur between chip lobe, thus avoid the change of current transformer output electric current, improve the output current precision of current transformer.Higher due to the output current precision of current transformer again so that the electric current that Motor Control and protection switch are detected is more accurate, thus is truly realized the purpose protecting motor.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 4, superposed type current transformer core of the present utility model is formed by two iron core unit 2 docking.Described iron core unit 2 is to be stacked by the chip lobe 3 that multiple shapes are identical to form.Wherein, the two sides of described chip lobe 3 is machined with pit 1 and protruding 4 respectively, and described pit 1 is identical and corresponding with the shape of protruding 4, and in the present embodiment, the shape of described pit 1 and projection 4 is rectangle.In two adjacent chip lobes 3, the pit 1 on the proximal surface of a chip lobe 3 is corresponding with the projection 4 on another chip lobe 3 proximal surface, and the projection 4 on chip lobe 3 proximal surface snaps in tight shape in the respective dimple 1 on another chip lobe 3 proximal surface.
Use this iron core, being not required to use bolt and screw to achieve that stacking between multiple chip lobe 3, fixing, even if running into vibrations, the situation that loosens also will not occur between chip lobe 3, thus avoid the change of current transformer output electric current, improve the output current precision of current transformer.Higher due to the output current precision of current transformer again so that the electric current that Motor Control and protection switch are detected is more accurate, thus is truly realized the purpose protecting motor.
