Description

Technical Field

[0001] The utility model relates to the technical field of mutual inductors, in particular to a fixing structure of a mutual inductor. Background Art

[0002] The instrument transformer is a commonly used sensor in electrical systems. It is used to measure electrical parameters such as current and voltage and convert them into signals that can be processed by the system. In power systems, the instrument transformer plays an important role in monitoring and protecting electrical equipment.

[0003] However, when installing large cables, especially those with large diameters, the weight and bending characteristics of the cables themselves may cause greater forces to the transformer structure once they come into contact with the transformer, increasing the risk of damage to the transformer. In addition, the cables generate heat during operation, and if they come into contact with the transformer, they may cause the transformer to overheat and affect its normal operation.

[0004] Therefore, those skilled in the art have proposed a fixing structure for a mutual inductor. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a fixing structure of a mutual inductor.

[0006] The technical solution of the utility model is as follows: a fixing structure of a transformer, comprising a connecting plate, the top of the connecting plate is fixedly connected to a mounting block, the top of the mounting block is fixedly connected to a transformer body, and the top of the connecting plate and the outer side of the transformer body are symmetrically fixedly connected to two vertical plates;

[0007] A limiting mechanism is arranged inside each of the vertical plates, and the limiting mechanism is used to prevent the large-diameter cable from contacting the transformer body for a long time;

[0008] The limiting mechanism includes a sliding rod, an adjusting plate, a control screw rod and a locking nut;

[0009] The slide bars are symmetrically slidably connected inside the corresponding vertical plates, and adjustment plates are fixedly connected between one ends of the corresponding slide bars. The control screw rods are threadedly connected inside the corresponding adjustment plates.

[0010] Through the above technical means, the adjusting plate can be driven to move by controlling the screw rod, and the position of the sliding rod can be controlled by the movement of the adjusting plate.

[0011] As a preferred implementation, one end of each of the control screw rods is rotatably connected to the outer side of the corresponding vertical plate, and a locking nut is threadedly connected to the outer side of each of the control screw rods.

[0012] Through the above technical means, the screw rod can be controlled to limit its position by turning the locking nut.

[0013] As a preferred embodiment, the limiting mechanism further includes an adjusting screw rod and an adjusting nut;

[0014] The adjusting screw rods are all movably connected to the inside of the corresponding sliding rods and one end thereof extends to the outside of the sliding rods. The outsides of the adjusting screw rods are all provided with key slots, and the insides of the sliding rods are all provided with flat keys used to cooperate with the key slots. The adjusting nut is rotatably connected to the outside of the corresponding sliding rods and is threadedly connected to the corresponding adjusting screw rods.

[0015] Through the above technical means, the adjusting screw can be driven to move by rotating the adjusting nut, and the position of the limit end can be further controlled by controlling the position of the adjusting screw.

[0016] As a preferred embodiment, the adjustment mechanism further includes a rotating ear, a rotating block and a limiting plate;

[0017] The rotating ears are all fixedly connected to one end of the corresponding adjusting screw rod, the rotating blocks are all rotatably connected to the corresponding rotating ears, and the limiting plates are all fixedly connected to the corresponding rotating blocks.

[0018] Through the above technical means, the position of the limit plate can be supplemented by providing the rotating ears and the rotating blocks, so that the limit plate can better fit the cable when it contacts the cable.

[0019] As a preferred implementation, the two limit plates are rotatably connected, and a connecting rod is fixedly connected between the corresponding two limit plates.

[0020] Through the above technical means, the rotation connection of the limit plate can further fit the cable, and the connecting rod can connect the two limit plates without blocking the normal operation of the transformer body.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] The utility model can limit the cable through the limiting mechanism, so that the cable will not fit into the transformer body and maintain a relatively central position. On the other hand, the cable with a large bending angle can be further limited by the limiting mechanism, so that the cable can be properly fixed. The advantage of this is that the cable can be in a relatively central position, the transformer can work better, and the heating of the cable will not affect the transformer. Some large-diameter cables will not directly apply force to the transformer, which can protect the transformer. BRIEF DESCRIPTION OF THE DRAWINGS
