[0020] Further, the material of the cylindrical shielding body 1 is selected from a metal material with high electromagnetic shielding performance, which can preliminarily reflect and absorb external electromagnetic fields.

[0021] Further, the intermediate electrode 2 is arranged in the cylindrical shielding body 1, and through reasonable potential configuration, it can adjust the electric field distribution inside the device, so as to offset the interference of the external electric field. The intermediate electrode 2 is connected with an external power supply or control system to realize accurate control of the potential.

[0022] Further, the Rogowski coil 3 is used for measuring the current change through the device. It has the characteristics of high precision and wide frequency band measurement. Through the monitoring of the current change, the working state of the device in the electromagnetic environment can be understood in real time, and data support is provided for the optimization and fault diagnosis of the device.

[0023] Further, the primary guide rod 4 is a key component for current transmission, and its material has high conductivity to ensure that the current can smoothly enter and exit the device. The primary guide rod 4 is connected with an external circuit, and its design considers the current-carrying capacity and the reliability of electrical connection.

[0024] Preferably, a high-voltage shell 5 is arranged outside the cylindrical shielding body 1, and the high-voltage shell 5 surrounds the entire internal structure of the device.

[0025] Further, the high-voltage shell 5 surrounds the entire shielding device, and its function is to provide mechanical protection and insulation. The high-voltage shell 5 is made of a material with high strength and high insulation performance, which can withstand the high voltage possibly generated inside the device and prevent the influence of external mechanical damage on the internal components.

[0026] Preferably, a grounding electrode 6 is installed on the high-voltage shell 5.

[0027] Further, the grounding electrode 6 is used for guiding the static electricity and excess charge generated by the device into the ground; the design of the grounding electrode 6 ensures good grounding performance, and the static electricity accumulation of the device can be eliminated through grounding, thereby enhancing the electromagnetic shielding effect.

[0028] Preferably, the intermediate electrode 2 is connected with an external power supply or control system to realize accurate control of the potential.

[0029] Example two:

[0030] The working principle of the utility model is as follows:

[0031] (I) electromagnetic shielding principle:

[0032] 1. When the external electromagnetic field acts on the device, the cylindrical shielding body 1 generates induced current on its surface based on the principle of electromagnetic induction. According to Lenz's law, the magnetic field generated by the induced current is opposite to the direction of the external magnetic field, thereby playing a role of offsetting and attenuating the external magnetic field.

[0033] 2. The intermediate electrode 2 generates a reverse electric field by applying an appropriate potential, which neutralizes the external electric field. The principle of electric field shielding is to use electrostatic induction to generate an induced charge on the intermediate electrode 2 to form a reverse electric field, reducing the influence of the external electric field on the inside of the device.

[0034] 3. Rogowski coil 3 measures current based on the principle of electromagnetic induction. When current passes through the primary lead 4, the Rogowski coil 3 will generate an induced electromotive force, which is proportional to the rate of change of the current passing through. By measuring and processing the induced electromotive force, the real-time change of the current can be obtained.

[0035] (II) Electrical connection and insulation:

[0036] 1. The electrical connection between the intermediate electrode 2, the Rogowski coil 3 and the primary lead 4 adopts high-precision welding or bolt connection method to ensure the reliability and low resistance characteristics of the connection.

[0037] 2. The high-voltage shell 5 and the internal components are isolated by insulating materials to prevent high voltage discharge between internal components. The selection of insulating materials is determined according to the maximum voltage that the device can withstand and the working environment.

[0038] The specific assembly method is:

[0039] At the beginning of assembly, the intermediate electrode 2 is accurately installed inside the cylindrical shielding body 1. This process helps to ensure the accuracy of the electrode position, and then the intermediate electrode 2 is firmly fixed by bolt fastening or welding.

[0040] After the intermediate electrode 2 is properly installed, the Rogowski coil 3 and the primary lead 4 are installed. When they are installed on the intermediate electrode 2, they must be carefully electrically connected according to the design requirements, and the connection means can be selected by welding or bolt connection. After completing the connection, in order to ensure the stability of the subsequent operation of the device, the reliability of the connection needs to be tested to prevent problems such as loose connection.

[0041] When the above-mentioned internal components are assembled, the internal components can be put into the high-voltage shell 5. In order to protect the internal components from the external environment, the high-voltage shell 5 is sealed by using sealing glue or sealing pads during the putting process, so as to effectively block the external dust and moisture from invading the device and causing damage to the components; the last step of the assembly is to install the grounding electrode 6. When the grounding electrode 6 is installed on the high-voltage shell 5, the key is to ensure that the grounding electrode 6 can be well connected with the ground.
