[0018] The outer shape of the insulating body includes a cylindrical shape or a rectangular box shape. The connecting and fixing structure is used to connect the generator and the motor.

[0019] This embodiment provides Figure 1 A schematic structural diagram of an insulating energy transmission device is shown in FIG. Figure 1 In the embodiment, the insulating body is a cylindrical insulating transmission shaft with a cavity structure, and a monitoring and protection unit is arranged on the surface of the insulating body and near the energy transmission unit according to actual needs.

[0020] In this embodiment, the structural diagram of the energy transmission unit and the electrical equipment is as follows: Figure 2 shown.

[0021] Combination Figure 2 The high-frequency converter includes a rectifier module, an inverter module, and a control module. The rectifier module, the inverter module, and the control module are connected in series in sequence to convert high-voltage electric energy into high-frequency alternating current to improve transmission efficiency and reduce energy loss during transmission. Among them, the high-voltage electric energy converts the input alternating current into direct current through the rectifier module, and the direct current enters the inverter module to convert the direct current into high-frequency alternating current. The control module monitors the input voltage, current, output voltage, current and other electric energy parameters in real time, and calculates and adjusts the operating frequency and duty cycle of the inverter module according to the electric energy parameters to ensure the quality and stability of the output electric energy.

[0022] The filter circuit is a circuit with a filter network composed of inductors, capacitors, and resistors, which is used to filter out high-frequency noise and ensure the stability and purity of the transmitted electric energy. When the receiving end induction coil receives the high-frequency electric energy signal sent by the transmitting end induction coil through the principle of electromagnetic induction, the high-frequency electric energy signal may contain a high-frequency noise signal. Therefore, the high-frequency noise signal is filtered by a capacitor, that is, the high-frequency noise signal is absorbed by the capacitor and converted into electric charge and stored on the two plates of the capacitor, thereby reducing the high-frequency noise signal in the output voltage; the high-frequency noise signal after the capacitor filtering is then filtered by the inductor, that is, the current generated by the high-frequency electric energy signal is smoothed by the inductor to reduce the high-frequency fluctuation in the output current; the high-frequency electric energy signal after filtering by the capacitor and the inductor becomes more stable and smooth, and the RC filter network or RL filter network formed by the resistor, capacitor, and inductor is used to further control the range of the output voltage and current obtained by the high-frequency electric energy signal for use by electrical equipment.

Among them, the temperature sensor is used to monitor whether the temperature of the electromagnetic induction coil is abnormal, and the current sensor is used to monitor whether the current of the electromagnetic induction coil is overloaded. If the temperature is abnormal and / or the current is overloaded, the comparator triggers the action of the actuator and quickly cuts off the circuit in the energy transmission unit to protect the safety of the entire insulated energy transmission device.

[0024] Furthermore, the electromagnetic induction coil is made of a material with high magnetic permeability, low resistivity and corrosion resistance. The electromagnetic induction coil is used to convert high voltage electric energy into low voltage electric energy in a non-contact manner by using the electromagnetic induction principle. In actual work, the number of turns and the cross-sectional shape of the electromagnetic induction coil can be optimized according to the actual needs of the insulating energy transmission device, which can significantly improve the electromagnetic performance, stability and reliability of the electromagnetic induction coil.

[0026] Among them, ceramic matrix composite materials include ceramic PE / EVA / MH / PCS composite materials, glass fiber reinforced epoxy resin composite materials, ceramic PE / EVA / MH / PCS composite materials, polypropylene, and silicone rubber. Figure 3 shown.

[0027] Most preferably, the surface of the insulating body is made of nano-ceramic-based composite material among ceramic-based composite materials.

[0028] In this embodiment, the nano-ceramic-based composite material is coated on the surface of the insulating body by chemical vapor deposition process, so that the surface of the insulating body has a uniform and dense protective layer. Among them, the nano-ceramic-based composite material has excellent high temperature resistance, corrosion resistance and arc resistance, and can effectively improve the service life and safety of the insulating body.

[0029] Preferably, the monitoring and protection unit is provided with a sensor module, a data acquisition and protection module, and a data storage and monitoring module; the sensor module, the data acquisition and protection module, and the data storage module are connected in sequence.

[0030] Furthermore, the sensor module is provided with a sensor array consisting of a temperature sensor, a humidity sensor, and an electric field strength sensor; the data acquisition and protection module is provided with a signal processing component, a threshold analysis component, a fault warning component, and a device protection component.

[0031] In this embodiment, the sensor array includes a temperature sensor array, a humidity sensor array, and an electric field strength sensor array; Among them, the temperature sensor array is composed of at least three temperature sensors, each temperature sensor is connected to the data acquisition and protection module through an independent signal line, and is distributed in the key heat dissipation areas and potential heating positions of the insulating energy transmission device, such as the heating point of the electromagnetic induction coil, near the AC power supply, etc.; the humidity sensor array is composed of at least two humidity sensors, each humidity sensor is connected to the data acquisition and protection module through an independent signal line, and is distributed in the area inside the insulating energy transmission device that may be affected by humidity, and is used to monitor the humidity level inside the insulating energy transmission device in real time; the electric field strength sensor array is composed of at least four electric field strength sensors, each electric field strength sensor is connected to the data acquisition and protection module through an independent signal line, and is distributed near the electromagnetic induction coil to form a comprehensive monitoring of the electric field strength, which can reflect the distribution and changes of the electric field strength in real time.

[0032] Preferably, the connecting and fixing structure includes a bolt, a plug-in connector, and a base. The bolt and the plug-in connector are respectively connected to the two ends of the base. The bolt is threadedly connected to the insulating body. The plug-in connector includes a plug-in connection port and a plug. A metal-plated connection point is provided at the top of the plug.

[0033] Furthermore, the metal-plated layer connection point is a gold-plated layer connection point or a silver-plated layer connection point.

[0034] This embodiment provides Figure 4 Schematic diagram of the connection and fixing structure shown. Figure 4In the plug-in connector, one end with a plug-in connection port can be installed on the electrical equipment or transmission line through the base, and the end with a plug is installed on the insulating body through the base. When the plug is inserted into the plug-in connection port, the insulating energy transmission device can be connected and fixed to other electrical equipment or transmission lines. The advantage of the connection and fixing structure is that it is convenient for workers to quickly and easily connect or disconnect the connection process between the insulating body and the electrical equipment, ensure the continuity and stability of the transmission process, and effectively improve the work efficiency.

[0035] This embodiment provides Figure 5 The schematic diagram of the working principle of the energy transmission unit shown in FIG. Figure 6 The working principle diagram of the monitoring and protection unit is shown in Figure 1. Figure 5 , Figure 6 The working principle of the insulating energy transmission device provided in this embodiment is as follows: When the insulated energy transmission device is used to transmit energy, the energy transmission unit uses the electromagnetic induction principle to convert high-voltage electric energy into a form suitable for transmission, and transmits it through the insulating body, so that the high-voltage electric energy can be efficiently transmitted to the low-voltage side, while ensuring the normal operation of the electrical equipment, maintaining the stability and safety of the transmission process; The sensor module in the monitoring protection unit is used to monitor the working status of the insulating energy transmission device in real time, including monitoring the working signals such as current, voltage, and temperature of the insulating energy transmission device; the signal processing component of the data acquisition protection module collects the working signal, performs noise reduction and filtering processing to obtain the working data, and analyzes the working data through the threshold analysis component. If the analysis finds that the device is in abnormal environmental conditions such as too high or too low temperature and humidity, excessive electric field strength, or potential safety hazards, the fault warning component responds quickly and issues an alarm. At this time, the device protection component initiates protection measures such as cutting off the energy transmission between the insulating energy transmission device and the electrical equipment, adjusting the working mode of the insulating energy transmission device, etc., to ensure the safety of energy transmission and the surrounding environment; the working data is stored through the data storage module for subsequent processing of the working data.

[0036] It should be noted that the steps of initiating the protection measures of cutting off the energy transmission between the insulating energy transmission device and the electrical equipment include: the device protection component immediately sends a cut-off instruction to the relevant electrical equipment, and stops the operation of the energy transmission unit after the cut-off instruction is executed. The device protection component monitors the status of the relevant circuits in the insulating energy transmission device to ensure that the energy transmission has been completely terminated, thereby avoiding further damage or risks.

[0037] The steps of initiating the protection measures for adjusting the working mode of the insulating energy transmission device include: after cutting off the energy transmission, the device protection component will analyze the working data according to the threshold analysis component to further evaluate the safety of the current working environment, including whether the temperature, humidity, and electric field strength have returned to the normal range. If the current working environment is still unsafe or needs further optimization, the device protection component will adjust the working mode of the insulating energy transmission device according to the preset safety strategy. The working mode includes but is not limited to continuing to stop the working of the insulating energy transmission device and starting the working of the insulating energy transmission device. When the working mode is adjusted, the device protection component will continue to monitor the status and environmental conditions of the device to ensure that the adjustment achieves the expected effect.

[0038] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them. The protection scope of the present invention is not limited thereto.
