Description

Technical Field

[0001] This utility model belongs to the technical field of current transformer housings, specifically relating to a modular current transformer housing that is easy to install. Background Technology

[0002] A current transformer, also called a converter, is an instrument that measures current by converting a large primary current into a small secondary current based on the principle of electromagnetic induction. The working principle of a current transformer is based on the law of electromagnetic induction. When the current being measured passes through the primary winding, an alternating magnetic field is generated in the iron core. This magnetic field is conducted through the iron core to the secondary winding, thereby inducing a current in the secondary winding. The magnitude of the induced current is proportional to the primary current, but in opposite phase. The current transformer casing is a component that protects the internal components, isolating the internal live parts from the external environment to prevent electric shock to personnel and short circuits in equipment, ensuring operational safety.

[0003] In the existing technology, when installing current transformers, due to the complex internal space of the distribution cabinet and the dense arrangement of wires, the reserved installation position of the transformer cannot be matched with the wires carrying the primary current. When the wires carrying the primary current pass through the center hole of the current transformer, the primary current wires cannot be centered, which leads to inaccurate measurement values, poor adaptability, and poor practicality.

[0019] Please refer to the following: Figure 1The present invention provides a convenient modular current transformer housing for easy installation. The convenient modular current transformer housing uses a plane where the projection of the conductors is a straight line as the mounting plane, the extension direction of the conductor projection as a first direction, and a direction perpendicular to the first direction and parallel to the mounting plane as a second direction. The convenient modular current transformer housing includes: a fixing base 10, an adjusting mechanism 20, and a housing body 30. Two fixing bases 10 are provided, spaced apart at pre-installation positions. The adjusting mechanism 20 is slidably mounted on each fixing base 10, and has a hinge position that allows for pitch and rotation. The rotation axis of the hinge position is set along the second direction. The housing body 30 is mounted on the hinge position and pitches and rotates with the hinge position.

[0020] The modular current transformer housing provided in this embodiment offers convenient installation, allowing for dual adjustment of installation position and angle compared to existing technologies. It solves the problem of misaligned conductors, ensuring measurement accuracy. Components can be independently manufactured, assembled, and maintained, reducing costs. It is compatible with different types of iron core windings, improving versatility and adaptability. Installation requires no complex tools, improving construction efficiency and reducing errors.

[0021] In some embodiments, the adjustment mechanism 20 may employ, for example... Figure 1 The structure shown. See also Figure 1 The adjusting mechanism 20 includes a sliding plate 21 and a hinge seat 22. The sliding plate 21 is slidably disposed on each fixed seat 10 along a first direction. One end of the hinge seat 22 is hinged to the sliding plate 21, the hinge axis is disposed along a second direction, and the other end of the hinge seat 22 extends outward, with the extended end of the hinge seat 22 being the hinge position.

[0022] The adjustment mechanism 20 consists of a sliding plate 21 and a hinge seat 22, separating the position and angle adjustment functions. The sliding plate 21 adjusts linearly along a first direction to compensate for distance deviations without disassembling the fixed base 10. The hinge seat 22 rotates in a second direction to accommodate wire tilt. This clear division of adjustment functions improves installation efficiency. The modular design facilitates individual replacement and maintenance, reducing costs. Its compact structure and small footprint make it suitable for dense installation environments.

[0023] In some embodiments, the hinge seat 22 may be adopted as follows: Figure 1 The structure shown. See also Figure 1The hinge base 22 includes: a hinge plate 221, a connecting plate 222, a connecting bolt 223, and a connecting nut 224. Two hinge plates 221 are provided, spaced apart along a first direction on the sliding plate 21. The connecting plate 222 is integrally connected to the two hinge plates 221, serving as the hinge position. One end of the connecting bolt 223 abuts against one of the hinge plates 221, and the other end extends along a second direction, passing through the sliding plate 21 and both hinge plates 221. The connecting nut 224 abuts against the other hinge plate 221 and is threadedly connected to the protruding end of the connecting bolt 223. Rotation of the connecting nut 224 causes the two hinge plates 221 to clamp the sliding plate 21, thereby fixing the pitch angle of the two hinge plates 221.

[0024] The sliding plate 21 is provided with a connecting hole 211 for the connecting bolt 223 to pass through.

[0025] The pitch angle is precisely fixed through the combination of hinge plate 221, connecting plate 222, and bolts and nuts. The three-point hinge structure ensures smooth rotation and improves the accuracy of angle adjustment. The bolts and nuts lock the angle, preventing vibration deviation and ensuring measurement stability. The threaded connection facilitates disassembly and readjustment, adapting to calibration and maintenance. The one-piece molded connecting plate 222 enhances structural strength, supports the outer shell 30 and the iron core winding, and extends service life. The connecting hole 211 provides a bolt mounting channel, ensuring reliable connection.

[0026] In some embodiments, the sliding plate 21 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The connecting hole 211 on the sliding plate 21 is a through hole, which is used to allow the connecting nut 224 to slide along the first direction.

[0027] The connecting hole 211 is designed as a through hole, allowing the connecting nut 224 to slide along the first direction. This expands the adjustment range of the adjustment mechanism 20, enabling coordinated position and angle adjustments. It prevents the connecting hole 211 from obstructing the displacement of the sliding plate 21, accommodating larger distance deviations. It provides buffer space for angle adjustment, avoiding structural interference. This improves the flexibility and accuracy of installation and calibration. The simple structure requires no additional parts, reducing production costs. It addresses complex installation scenarios, ensuring wire centering and improving adaptability and measurement reliability.

[0028] In some embodiments, the aforementioned fixing base 10 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 Each fixed base 10 is provided with a sliding groove 11, which is used to allow the sliding plate 21 to slide along the first direction.

[0029] The fixed base 10 is provided with a sliding groove 11 to guide and limit the sliding plate 21. This restricts the sliding plate 21 to slide only along a first direction, preventing offset and tilting, and ensuring alignment accuracy. It enhances the stability of the connection between the sliding plate 21 and the fixed base 10, preventing shaking and detachment. It facilitates the installation and removal of the sliding plate 21, simplifying operation. The structure is compact, occupying little space, and suitable for dense environments. The manufacturing process is simple, reducing costs. It reduces sliding friction, saving effort and improving installation efficiency.

[0030] In some embodiments, the aforementioned fixing base 10 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 Each fixed seat 10 is provided with a fixing screw 12, which is used to penetrate the side wall of the slide groove 11 and abut against the side wall of the sliding plate 21.

[0031] The mounting base 10 is equipped with fixing screws 12 to lock the position of the sliding plate 21. This prevents positional displacement caused by vibration or external forces, ensuring stable installation accuracy. The structure is simple and easy to operate, requiring no additional locking components, reducing complexity and cost. The threaded connection allows for adjustable locking force, preventing deformation of the sliding plate 21. It facilitates unlocking and readjustment, adapting to calibration and maintenance. It resists the effects of equipment vibration and thermal expansion and contraction of wires, maintaining alignment between the center hole and the wires, improving structural reliability and operational stability.

[0032] In some embodiments, the aforementioned fixing base 10 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 Each mounting base 10 is equipped with a connecting screw 13, which is used to fix the corresponding mounting base 10 to the reserved installation position inside the electrical cabinet.

[0033] The mounting bracket 10 is equipped with connecting screws 13, enabling reliable installation and modular fixing. It provides stable support for the overall structure, preventing loosening of the mounting bracket 10 that could lead to decreased accuracy or equipment damage. Installation and disassembly are convenient, reducing construction difficulty and time costs. It adapts to different pre-reserved installation positions in distribution cabinets, improving versatility. The spacing and installation position of the two mounting brackets 10 can be adjusted, enhancing adaptability. The fixing method does not damage the distribution cabinet structure, reducing installation risks.

[0034] In some embodiments, the aforementioned housing body 30 may adopt the following... Figure 1 The structure shown. See also Figure 1 The outer casing 30 has a mounting cavity for placing the iron core winding.

[0035] The outer casing (30mm) features a mounting cavity to accommodate and secure the iron core winding. This prevents displacement, collision, or damage to the iron core winding, ensuring the integrity of the electromagnetic induction structure. It isolates the casing from the external environment, providing dust, moisture, and corrosion protection, extending the service life of the iron core winding. Enhanced casing insulation reduces the risk of electric shock and short circuits, meeting safety standards. Reduced external vibration and magnetic field interference ensures stable conduction of the alternating magnetic field, improving measurement accuracy. The integrated structure is compact and rational, requiring no additional fixing components, reducing assembly complexity and production costs.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
