Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5 The device shown is a current transformer coil clamping device for an energy meter, including a current transformer body 1;

[0025] A connecting block 2 is provided at the top of the transformer body 1, a base 4 is provided at the bottom of the transformer body 1, a coil 5 is provided inside the transformer body 1, a copper wire 6 is provided outside the coil 5, and a ring array of copper wire 6 is provided outside the coil 5.

[0027] The clamp assembly 9 is arranged in a circular array of four. A clamping platform 11 is provided at the top of the clamp assembly 9.

[0030] A front cover 3 is provided at the middle position of the front side of the transformer body 1, and a groove 7 is provided at the outer side of the inner cavity of the transformer body 1.

[0031] The groove 7 corresponds to the front cover 3, and the groove 7 and the front cover 3 are nested together.

[0032] The transformer body 1, connecting block 2 and base 4 are made of plastic. The coil 5 is connected to the transformer body 1 through the clamp assembly 9.

[0033] In this embodiment, the specific implementation steps of a current transformer coil clamp device for an energy meter are as follows: First, a suitable installation location needs to be selected. The specific location should be determined according to the actual situation and installation requirements. Ensure that the installation environment is clean, dry, and free from significant electromagnetic interference. This helps to ensure the normal operation and accurate measurement of the current transformer coil 5. According to the circuit connection method and the type of current transformer coil 5, the coil 5 is correctly installed in the circuit. If it is a current transformer, the conductor of the current to be measured usually needs to be passed through the center hole of the coil. If it is a voltage transformer, the coil 5 needs to be correctly connected to the voltage measurement point of the circuit. Ensure that the coil 5 is installed firmly and will not move or be damaged due to vibration or external force. Fix the coil by the clamp assembly 9 inside the mounting base 10. After installation, perform necessary tests and calibrations to ensure that the measurement data of the current transformer coil 5 is accurate and reliable. Perform zero-point calibration and range calibration, etc. During the installation process, pay attention to safety and avoid electric shock or other accidents. If it is necessary to install the current transformer coil in a high-voltage circuit, it should be operated by a professional and necessary safety measures should be taken.

[0034] like Figure 2-5As shown, a mounting base 10 is provided at the bottom of the coil 5, a clamp assembly 9 is provided above the mounting base 10, a disassembly piece 16 is provided at the rear of the mounting base 10, four clamp assemblies 9 are arranged in a circular array, a clamping platform 11 is provided at the top of the clamping platform 9, a clamping hand 8 is provided on the left and right sides of the clamping platform 11, a connecting piece 14 is provided at the bottom of the clamping hand 8, a sliding cavity 12 is provided in the middle of the inside of the clamping hand 8, a support rod 13 is provided on the left and right sides of the clamping platform 11, a sliding rod 15 is fixedly connected to the bottom of the clamping platform 11, the clamping hand 8 is rotatably connected to the mounting base 10 through the connecting piece 14, the support rod 13 is slidably connected to the sliding cavity 12, the sliding rod 15 is slidably connected to the mounting base 10, the sliding rod 15 is fixedly connected to the disassembly piece 16, and the disassembly piece 16 is slidably connected to the transformer body 1.

[0035] Preferably, the mounting base 10 is located at the bottom of the coil 5, and its main function is to fix the coil 5 and keep it stable during operation. The chuck assembly 9 is located at the top of the coil 5, and its function is to clamp the coil 5. The disassembly piece 16 is located at the rear of the coil 5, which helps the user to remove the coil 5 more quickly and safely. The clamping platform 11 is located at the top of the coil 5, and its presence provides another fixing point, which helps to make more precise control of the coil 5 during processing. The grippers 8 are located on the left and right sides of the coil 5, and their main function is to assist in fixing the coil 5, especially when it is necessary to fix or support the coil 5 laterally. The grippers 8 may be designed to be adjustable to accommodate coils 5 of different sizes and shapes. The slide bar 15 is located at the bottom of the coil 5 and is fixedly connected to the disassembly piece 16. The main function of the slide bar 15 is to provide a sliding support point, which makes it easier and faster to replace or maintain the coil 5. Together, they constitute a complex and efficient coil 5 fixing and maintenance system. The design of this system not only ensures the stability of the coil 5 during processing, but also greatly simplifies the replacement and maintenance of the coil 5, and improves maintenance efficiency and product quality.

[0036] like Figure 1-3 and Figure 5 As shown, a front cover 3 is provided at the middle position of the front side of the transformer body 1, and a groove 7 is provided at the outer side of the inner cavity of the transformer body 1. The groove 7 corresponds to the front cover 3, and the groove 7 and the front cover 3 are nested and connected.

[0037] Preferably, the front cover 3 is used to enclose the transformer body 1, which can protect the coils and other sensitive components inside the transformer from the influence of the external environment, such as dust and humidity. The slot 7 provides space for installing and fixing the transformer coils. The nested connection between the front cover 3 and the slot 7 is a common mechanical connection method that can improve the overall structural stability of the transformer. This design usually means that the slot 7 can fit tightly with the front cover 3, thereby reducing the vibration and noise of the transformer during use.

[0038] like Figure 1-5 As shown, the transformer body 1, connecting block 2 and base 4 are made of plastic, and the coil 5 is connected to the transformer body 1 through the clamp assembly 9.

[0039] Optionally, plastic is an excellent insulating material that can effectively isolate the electrical connection between the transformer body and the connecting block and the surrounding environment, reducing the risk of electrical faults and improving the safety and stability of the transformer. The plastic transformer body has relatively low resistance to electromagnetic wave propagation and interference, which helps to reduce external interference during coil measurement and improves measurement accuracy. The coil 5 is connected to the transformer body 1 through the clamp assembly 9, which enhances the stability of the device and increases its service life.
