Description

Technical Field

[0001] The present invention relates to a DC zero-point leakage protector based on artificial intelligence. Compared with conventional AC zero-point leakage protectors, this zero-point leakage protector has expanded the AC range to the DC field, and the traditional relay elements and mechanical releases are abandoned in the protection device; in terms of control mode, a high-speed microprocessor and MOS tube based on AI technology are adopted, and fixed-point, floating-point and DSP algorithms and AI reasoning operations are supported. The action response time is at least one order of magnitude faster than that of the traditional zero-point leakage protector; in terms of topological structure, the control and the junction box are combined into one, which is suitable for the protection of both AC circuits and DC circuits, and is particularly safe, and can be widely used in various fixed or mobile high-power electrical equipment.

[0002] Under normal circumstances, the live and neutral currents in an AC circuit are equal in magnitude and opposite in direction, that is, the vector sum of the currents is zero; once the power factor of the system drops severely, causing the midpoint voltage to drift, part of the current will flow back through an abnormal path, causing the vector sum of the currents in the live and neutral lines to no longer be zero, and leakage will occur; similarly, in DC circuits, circulating currents caused by unequal potentials caused by multi-point grounding or creepage effects are prone to electric shock accidents caused by leakage in electrical equipment.

[0003] Conventional AC zero-point leakage protectors are basically implemented using outdated zero-sequence current transformers (ZTC) or residual current transformers (RTC). Once the leakage current is detected to exceed the set threshold, the electromagnetic component will automatically trigger the release to cut off the power supply; therefore, in terms of working principle, the action response time of traditional AC zero-point leakage protectors should be in milliseconds or longer.

[0004] This is why the zero-point leakage protector needs to be inspected and tested regularly in order to maintain its normal function; however, for a system with an ungrounded neutral point, the zero-point leakage protector usually cannot work properly because the zero-sequence current transformer (ZTC) cannot detect the leakage current due to the lack of a reference potential.

[0005] Therefore, the original intention of the design of the present invention is mainly to solve how to convert the zero-sequence current leakage protection problem in an AC power environment into the leakage protection problem in a DC power supply environment, or to make this zero-point leakage protector suitable for both AC circuits and DC circuits. This is particularly practical for electric vehicles using power battery packs, because when an electric vehicle has an accident, the explosion time of the power battery pack usually occurs within milliseconds. It is very necessary to take preventive measures and quickly cut off the DC power supply.

[0006] The most amazing thing about the zero-point leakage protector based on artificial intelligence is its fast response protection capability. When dangerous leakage charge has not yet accumulated, it can quickly cut off the power supply of the power battery pack within microseconds. Moreover, at the moment of switch action, there is no electromagnetic arcing phenomenon, nor electrical corrosion between contacts. This not only extends the service life of the protection device, but also acts faster and has higher reliability than traditional protection devices with electromagnetic tripping. In terms of control means, the present invention application adopts the core microcontroller chip ESP32-S3 based on artificial intelligence technology. The chip supports fixed-point, floating-point and DSP algorithms, supports AI high-speed reasoning operations, and can convert its AI model into the format of an embedded zero-point leakage protector device in DeepSeek mode.

[0007] The basic principle of the zero-point leakage protector based on artificial intelligence is that the circuit of this zero-point leakage protector has an input digital current transformer and an output digital current transformer. The characteristics of these two digital current transformers are that they have basically the same appearance, but can be set horizontally or vertically. The control circuit can quickly detect whether the input current and the output current are balanced, so that the current balance state can be closely monitored to accurately determine whether there is leakage in the system. If there is no leakage, the vector sum of the input and output currents is zero; if the power factor drops or there is leakage current, the balance of the current vector sum will be broken, and the MOS tube in the zero-point leakage protector will quickly cut off the power supply to prevent the risk of fire caused by electric shock or power battery explosion, thereby achieving the purpose of zero-point leakage protection.

[0008] In terms of topological structure design, the present invention application follows the principle of "overall minimum cost and system optimization". The control and junction boxes adopt a hybrid structure that combines two into one. The input digital current transformer adopts a horizontal form, and the output digital current transformer adopts a vertical form, so as to overcome the cross-induction interference between electromagnetic fields as much as possible.

[0009] Obviously, the AI-based zero-point leakage protector can be widely used in large mobile electronic devices, and can effectively reduce the incidence of electrical accidents and protect the safety of personnel and equipment. Summary of the invention

[0010] In view of this, the present invention introduces a zero-point leakage protector based on artificial intelligence, the specific contents of which are as follows: 1. The zero-point leakage protector based on artificial intelligence includes: protector upper cover, control and junction box, external wiring plug seat, PCB circuit board, and its key points are: The protector upper cover is a cylindrical structure with a hexagonal pit on the inner side; The control part of the control and junction box is a cavity structure with a circular exterior and a hexagonal interior, and the exterior of the junction box is a hexagonal column structure, and the two are combined into one to form the control and junction box; The external hexagonal column structure on the control and junction box is designed as the junction box end. The contact surface between the circular cylinder on the outside of the control and junction box and the upper cover of the protector has a hexagonal convex strip. During assembly, the upper cover of the protector is embedded in the hexagonal convex strip of the control and junction box through the hexagonal pit on the upper cover. After the cylindrical part of the control and junction box is hollowed out into a hexagonal inner cavity, the bottom of the hexagonal inner cavity wall extends out of the control and junction box step, five heat dissipation fixing holes are opened on each side of the hexagonal inner cavity wall of the control and junction box, a control and junction box central circular hole pit is opened at the center of the control and junction box, and an external wiring introduction hole is opened on the side wall of the central circular hole pit of the control and junction box; Each side of the hexagonal column of the control and junction box extends out an external wiring plug socket, and the external wiring plug socket is connected to the external wiring lead-in hole; The terminal box end of the hexagonal column of the control and junction box is designed with a circle of hexagonal groove interfaces, which are designed to prevent electromagnetic cross interference.

After the external wiring is connected through the external wiring plug socket, the screws at the wiring screw fixing holes can be tightened to fix the external wiring; The PCB circuit board is the control core of the zero-point leakage protector based on artificial intelligence. There is a through hole in the center of the PCB circuit board. The PCB circuit board is respectively welded with an ESP32-S3 microprocessor, a field programmable chip, a power driver chip, a universal driver, two-way digital temperature sensors for power devices, MOS tubes, horizontal input digital current sensors, vertical output digital current sensors, vertical common-mode inductors, SMD high-frequency transformers, photocouplers, SMD freewheeling diodes, and electrolytic capacitors; During installation, the PCB circuit board is placed on the junction box step in the hexagonal inner cavity of the control and junction box, and then screwed through the PCB circuit board fixing hole and connected to the mounting hole on the junction box step; The input digital current sensor is a horizontal structure. Although the structure has a screw fixing hole for the input digital current sensor, the simplest installation method is to directly solder the input digital current sensor pin to the central through hole of the PCB circuit board. The input current sensing signal is shaped and filtered by the field programmable chip and then sent to the corresponding pin of the ESP32-S3 microprocessor. The output digital current sensor is a vertical structure, and is fixed on the PCB circuit board by screws passing through the screw fixing holes of the output digital current sensor, and then the pins of the output digital current sensor are welded to the PCB circuit board, and the output current sensing signal is shaped and filtered by the field programmable chip and then sent to the corresponding pins of the ESP32-S3 microprocessor; The vertical common-mode inductor is designed to eliminate the common-mode interference signal on the output current side. Especially when an external motor is installed on the output side, it can greatly reduce the electromagnetic surge radiation and noise caused by the motor equipment when it is started, thereby improving the stability of the system. Each MOS tube is connected to a SMD freewheeling diode to eliminate the damage of reverse surge current to the MOS tube. The heat dissipation surface of the MOS tube is fixed to the heat dissipation fixing hole on the inner cavity wall by screws. The MOS tube is controlled by a photocoupler, which is controlled by the I / O pin of the ESP32-S3 microprocessor.

[0011] Furthermore, the protector upper cover plate and the control and junction box are all cast from aluminum at one time.

[0012] Furthermore, the ESP32-S3 microprocessor on the PCB circuit board is a domestically produced high-performance dual-core processor in a QFN56 package, which supports fixed-point, floating-point, DSP, Bluetooth and WiFi operations and uses a low-power power supply method.

[0013] Furthermore, the control and junction box itself is an equipotential junction box. The ground wire on the PCB circuit board is directly connected to the control and junction box and then grounded at a unified single point, thereby avoiding the impact of multi-point grounding loops caused by accidental multi-point grounding of electrical appliances.

[0014] Furthermore, the control and junction box is designed according to the explosion-proof and induction-proof levels. It realizes the operations of digging holes, grooving and dividing ribs at the junction box end at the same time through the dividing ribs and dividing grooves, so as to eliminate the influence of distributed capacitance and induced static electricity during the connection process as much as possible.

Beneficial Effects

[0024] In summary, the zero-point leakage protector based on artificial intelligence proposed in the present invention has the following significant beneficial effects: 1. The zero-point leakage protector based on artificial intelligence has a topological space design that combines the control and junction box into one and forms the main skeleton. Through the hexagonal cavity structure, it successfully solves the wiring problems of cables and the centralized heat dissipation problems of high-power MOS devices. The zero-point leakage protector supports equipotential wiring channels, thus completely eliminating the possibility of accidental multi-point grounding of the system and the influence of induced circulating current caused by potential differences after multi-point grounding.

[0025] 2. The biggest advantage of the zero-point leakage protector based on artificial intelligence is that it has a rapid response capability of microseconds and can cut off the power supply in a very short time. It is faster and more reliable than the protection device with electromagnetic tripping. Therefore, it is particularly suitable for power switching of new energy lithium battery packs to protect the safety of personnel and electrical equipment.

[0026] 3. The zero-point leakage protector based on artificial intelligence has an input digital current transformer and an output digital current transformer inside its circuit, so it can detect whether the input current and output current in the circuit are balanced with extremely high sensitivity, and closely monitor the balance state of the online current, so as to accurately judge whether there is leakage in the system. If there is no leakage, the vector sum of the current is zero; if there is leakage or a small leakage current, the balance of the current will be broken, and the power switch will respond quickly to cut off the power supply to prevent the fire hazard caused by electric shock or lithium battery explosion at a preventive speed, thereby achieving the purpose of zero-point leakage protection. Obviously, the zero-point leakage protector based on artificial intelligence can be widely used in large mobile devices similar to electric vehicles, and can effectively reduce the incidence of accidental electrical accidents; more importantly, this zero-point leakage protector has an action current control capability of several hundred amperes, which is difficult for conventional zero-point leakage protectors to do.

[0028] 5. The zero-point leakage protector based on artificial intelligence has abandoned the traditional electromagnetic circuit as the actuator and adopted the contactless high-speed MOS device. Therefore, at the moment of switch action, there is neither electromagnetic arcing phenomenon nor electrical corrosion between contacts, which greatly extends the service life of the high-speed switch.
