Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an intelligent leakage protection device for electrical equipment. Background Technology

[0002] Intelligent leakage current protection devices for electrical equipment are devices used to protect electrical equipment and personal safety. In current low-voltage power distribution systems, AC residual current operated protective devices need to be able to identify sinusoidal AC leakage current and pulsating DC leakage current. In recent years, with the popularization of nonlinear loads such as frequency converters and LED driver power supplies, there is a risk of false tripping or failure to trip when detecting composite waveform leakage current. Every year, electrical fire accidents caused by leakage current worldwide are directly related to the failure of protection devices.

[0003] A search revealed a Chinese patent publication number, CN221688172U, which discloses an intelligent electrical leakage protection device, relating to the field of electrical equipment technology. The device includes a housing with a base plate fixed to its lower surface. Multiple sets of wiring ports extending into the housing are provided on both the left and right outer walls of the housing. Two sets of protective frames are provided on either side of the wiring ports on the outer walls of the housing. Each set of protective frames has a constraint strip fixed to the housing at its upper and lower ends. A retractable rod is rotatably mounted inside each protective frame. This invention applies a relatively close external force to two sets of protective frames on the same side, causing them to move relative to each other and lock in place with the cooperation of constraint strips and trapezoidal strips. This achieves efficient and convenient fixing of external wires. When it is necessary to remove the wire, an external force is applied to the winding rod to rotate it and cause the trapezoidal strip to retract into the protective frame. This allows the two sets of protective frames to be pulled away from each other, enabling the wire removal process. This indirectly provides convenience for manual work. However, in existing intelligent leakage protection devices for electrical equipment, strong wide-area electromagnetic interference is generated by high-frequency electrical equipment and electromagnetic devices in industrial environments, causing frequent malfunctions of traditional leakage protection devices. Furthermore, due to defects in signal processing and algorithms, it is difficult to accurately identify composite waveform leakage currents, and it cannot balance high-sensitivity detection and reliable operation. The insufficient identification accuracy leads to the inability to guarantee industrial electrical safety. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an intelligent leakage current protection device for electrical equipment, which aims to improve the problem that the existing leakage current protection devices have insufficient recognition accuracy for composite waveform leakage current, and cannot achieve high-sensitivity detection and reliable operation.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent leakage protection device for electrical equipment, including a circuit breaker, a switch installed on the front side of the outer wall of the circuit breaker, a detection module fixedly connected to the right side of the outer wall of the circuit breaker, screws threadedly connected to the upper and lower ends of the outer wall of the circuit breaker, multiple support blocks fixedly connected to the top rear side of the circuit breaker, a fixing buckle rotatably connected to the front side of the outer wall of each of the multiple support blocks, an adjusting buckle rotatably connected to one side of the inner wall of the fixing buckle, and a fixing block rotatably connected to the right side of the outer wall of the adjusting buckle. One end of the fixed block is rotatably connected to a fixing plate, and the other end of the fixing plate is rotatably connected to the left side of the outer wall of the adjusting buckle. A power strip is fixedly connected to the bottom of the inner wall of the fixing buckle. A second contact plate is fixedly connected to the middle of the inner wall of the power strip. A socket is rotatably connected to the middle of the inner wall of the power strip. Connecting wires are fixedly connected to the left and right sides of the middle of the inner wall of the socket. A first contact plate is fixedly connected to the bottom of the outer wall of the socket. The first contact plate engages with the second contact plate. An adjusting mechanism is fixedly connected to the left side of the inner wall of the circuit breaker on the left side. The adjusting mechanism is used to shut down the electrical equipment.

[0006] The above technical solution involves the circuit breaker's detection module monitoring the current. Upon detecting a leakage current, the circuit breaker trips, cutting off the circuit to protect personnel and equipment. Users can manually control the circuit's on / off state via a switch. The circuit breaker is connected to a data cable via screws, transmitting circuit data to a control terminal or display device for remote monitoring. The data cable fixing structure consists of a support block, a fixing clip, and a fixing plate, adjustable to accommodate different data cable specifications. The circuit connection includes a power strip, a socket, and a contact plate. Inserting the socket into the power strip forms an electrical connection; removing it disconnects the circuit. The adjustment mechanism is fixed to the left side of the circuit breaker's inner wall; operating the adjustment mechanism cuts off the circuit and shuts down electrical equipment.

An adjusting rod is rotatably connected to the outer wall of the bolt. The rotating shaft is slidably connected to the middle of the inner wall of the adjusting rod. An arc-shaped groove is opened on the front side of the outer wall of the adjusting rod. The switch is slidably connected to the middle of the inner wall of the arc-shaped groove.

[0009] The above technical solution involves the system issuing an adjustment command, starting the motor, and driving the turntable and shaft to rotate. The movement of the shaft is converted into a push-pull force through the adjustment rod, causing the switch to slide within the arc-shaped groove. This automatically controls the opening and closing of the switch, reducing the risk of manual operation and making it suitable for dangerous environments and environments requiring frequent operation.

[0010] As a further description of the above technical solution:

[0011] A fixing groove is provided on the rear side of the outer wall of the circuit breaker.

[0012] The above technical solution provides a fixing groove on the rear side of the outer wall of the circuit breaker, which can be used with corresponding fasteners to ensure its stable installation in the distribution box or electrical equipment, maintain its stable position during operation, and prevent loosening from affecting operation and control.

[0013] As a further description of the above technical solution:

[0014] An indicator light is fixedly connected to the front side of the outer wall of the circuit breaker.

[0015] The above technical solution allows the indicator light to show the circuit breaker's operating status, lighting up when power is applied, making it easy to quickly understand the circuit's condition.

[0016] As a further description of the above technical solution:

[0017] A connecting plate is fixedly connected to the front side of the outer wall of the multiple switches.

[0018] The above technical solution enables the switches to be linked through a connecting plate, facilitating centralized control of the circuit and simultaneous operation of multiple circuits, thus ensuring the reliability and safety of circuit control.

[0019] As a further description of the above technical solution:

[0021] Through the above technical solution: the button is used to start the detection module, switch modes, and view data.

[0022] As a further description of the above technical solution:

[0023] A data interface is provided on the right side of the outer wall of the detection module.

[0024] The above technical solution involves transmitting detection module data to external devices via a data interface for storage, analysis, and display.

[0025] As a further description of the above technical solution:

[0026] A gasket is fixedly connected to the middle of the inner wall of the fixing buckle.

[0027] The above technical solution involves fixing the gasket to the inner wall of the fixing buckle, providing cushioning, anti-slip and sealing functions, ensuring stable installation of the detection module, preventing vibration from affecting detection accuracy, and avoiding interference from dust and moisture.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an intelligent leakage current protection device for electrical equipment, including a circuit breaker 1. A switch 3 is installed on the front side of the outer wall of the circuit breaker 1. A detection module 4 is fixedly connected to the right side of the outer wall of the circuit breaker 1. Screws 5 are threadedly connected to the upper and lower ends of the outer wall of the circuit breaker 1. Multiple support blocks 6 are fixedly connected to the rear top of the circuit breaker 1. Each support block 6 has a fixing buckle 7 rotatably connected to the front side of its outer wall. An adjusting buckle 8 is rotatably connected to one side of the inner wall of the fixing buckle 7. A fixing block 9 is rotatably connected to the right side of the outer wall of the adjusting buckle 8. A fixing plate 10 is rotatably connected to one end of the fixing block 9. The other end of 10 is rotatably connected to the left side of the outer wall of the adjusting buckle 8. The bottom of the inner wall of the fixing buckle 7 is fixedly connected to the power strip 15. The middle of the inner wall of the power strip 15 is fixedly connected to the contact plate 14. The middle of the inner wall of the power strip 15 is rotatably connected to the socket 11. The left and right sides of the middle of the inner wall of the socket 11 are fixedly connected to the connecting wires 12. The bottom of the outer wall of the socket 11 is fixedly connected to the contact plate 13. The contact plate 13 engages with the contact plate 14. The left side of the inner wall of the left circuit breaker 1 is fixedly connected to the adjusting mechanism 2. The adjusting mechanism 2 is used to close the electrical equipment. The rear side of the outer wall of the circuit breaker 1 is provided with a fixing groove 17.

[0040] Specifically, the detection module 4 of circuit breaker 1 monitors the current. When leakage is detected, it triggers circuit breaker 1 to trip, cutting off the circuit to protect personnel and equipment. Users can manually control the circuit on and off via switch 3. Screw 5 of circuit breaker 1 is used to connect the data cable, transmitting circuit data to the control terminal or display device for remote monitoring. The data cable fixing structure consists of support block 6, fixing buckle 7, and fixing plate 10. Users can adjust it to accommodate different data cable specifications. The circuit connection part includes power strip 15, socket 11, and contact plate. When socket 11 is inserted into power strip 15, an electrical connection is formed; when it is pulled out, the circuit is disconnected. Adjustment mechanism 2 is fixed on the left side of the inner wall of circuit breaker 1. When it is necessary to shut down the electrical equipment, the position or state of its internal structure is changed by operating adjustment mechanism 2, thereby cutting off the circuit and realizing the shutdown control of the electrical equipment. The fixing groove 17 on the rear side of the outer wall of circuit breaker 1 can cooperate with the appropriate fixing parts to securely install circuit breaker 1 in the distribution box or other electrical equipment, ensuring that the position of circuit breaker 1 is fixed during operation and avoiding the impact of loosening on its normal operation and control effect on the electrical equipment.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The adjusting mechanism 2 includes a motor 201, which is fixedly connected to the left side of the inner wall of the circuit breaker 1. A turntable 202 is fixedly connected to the output end of the motor 201. A rotating shaft 203 is fixedly connected to the right side of the outer wall of the turntable 202. A bolt 205 is threadedly connected to the rear side of the inner wall of the circuit breaker 1. An adjusting rod 204 is rotatably connected to the outer wall of the bolt 205. The rotating shaft 203 is slidably connected to the middle of the inner wall of the adjusting rod 204. An arc-shaped groove 206 is opened on the front side of the outer wall of the adjusting rod 204. A switch 3 is slidably connected to the middle of the inner wall of the arc-shaped groove 206. An indicator light 18 is fixedly connected to the front side of the outer wall of the circuit breaker 1. A connecting plate 19 is fixedly connected to the front side of the outer wall of multiple switches 3.

[0042] Specifically, after the system issues an adjustment command, the motor 201 starts, serving as a power source to drive the turntable 202 and the rotating shaft 203 to perform circular motion. The motion of the rotating shaft 203 is converted into the pushing and pulling force of the adjusting rod 204. Through the fulcrum of the bolt 205, the adjusting rod 204 swings, causing the switch 3 to slide within the arc-shaped groove 206, thereby realizing the automatic opening or closing of the switch 3. This reduces the risk of manual operation and is particularly suitable for dangerous or frequently operated environments. The indicator light 18 on the front side of the circuit breaker 1 is used to visually display its working status. When the circuit breaker 1 is running normally, the indicator light 18 lights up, helping the user to quickly grasp the circuit status. Multiple switches 3 are mechanically or electrically connected through the front connecting plate 19. The connecting plate 19 allows multiple switches 3 to operate in conjunction, facilitating centralized control of related circuits and also helping to enhance the stability and structural strength of the switch 3 installation, ensuring the reliability and safety of circuit control.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A button 20 is installed on the front side of the outer wall of the detection module 4, a data interface 21 is opened on the right side of the outer wall of the detection module 4, and a gasket 16 is fixedly connected to the middle of the inner wall of the fixing buckle 7.

[0044] Specifically, button 20 is used to trigger the detection operation of detection module 4 and switch modes or view data; data interface 21 can be used to transmit the data collected by detection module 4 to external devices for data storage, analysis and display; the gasket 16 on the inner wall of the fixing buckle 7 plays a role in buffering, anti-slip and sealing, ensuring that detection module 4 is installed firmly, avoiding the impact of vibration on detection accuracy, and preventing dust and moisture from entering and interfering with the normal operation of detection module 4.

[0045] Working Principle: The detection module 4 on the right side of the outer wall of circuit breaker 1 monitors the current in the circuit in real time. When leakage is detected, i.e., abnormal current shunting occurs in the circuit and exceeds the preset safety threshold, the detection module 4 quickly transmits a signal to circuit breaker 1, triggering the internal protection mechanism of circuit breaker 1 to trip and disconnect the circuit, preventing electric shock and damage to electrical equipment, thus achieving leakage protection. The switch 3 on the front side of the outer wall of circuit breaker 1 can be manually operated by the user. By turning switch 3 on or off, the entire circuit can be controlled. Under normal use, the user can flexibly control the circuit's operating status according to needs, such as turning on or off the power supply to electrical equipment. The screws 5 at the top and bottom of the outer wall of circuit breaker 1 are used to connect the data cable. The circuit data obtained by the detection module 4 is transmitted to an external control terminal or display device through the data cable, so that the user can understand the circuit's operating status in real time and perform remote monitoring and data analysis. The support block 6, fixing buckle 7, adjusting buckle 8, fixing block 9, and fixing plate 10 on the top rear side of circuit breaker 1 together constitute the data cable. The fixing and connection structure includes multiple support blocks 6 that support the fixing buckle 7. The fixing buckle 7, through the cooperation of the adjusting buckle 8, fixing block 9, and fixing plate 10, achieves convenient fixing and engagement of the data cable. Users can flexibly adjust the positions of the adjusting buckle 8 and fixing plate 10 according to the specifications and layout of the data cable, facilitating the operation of the connecting cable 12 and ensuring the data cable remains stable and secure during device operation. This prevents data transmission and circuit operation from being affected by data cable movement or poor contact. The bottom inner wall of the fixing buckle 7 contains a power strip 15, a socket 11, and a connector. Contact plate 13 and contact plate 14 form the circuit connection part. The socket 11 is connected to the electrical equipment through the connecting wire 12. When the socket 11 is inserted into the power strip 15, the contact plate 13 at the bottom of the outer wall of the socket 11 engages with the contact plate 14 in the middle of the inner wall of the power strip 15 to form an electrical connection, so that the current can be transmitted to the electrical equipment through the socket 11 to realize the circuit conduction. When it is necessary to disconnect the circuit, rotate the socket 11, and the contact plate 13 and contact plate 14 separate, and the circuit is disconnected, thereby realizing the connection and disconnection control of the circuit.

[0046] When the system issues a command to adjust switch 3 of circuit breaker 1, motor 201 is energized and starts. Motor 201, fixed to the left side of the inner wall of circuit breaker 1, serves as the power source for the entire adjusting mechanism 2 and begins continuous operation. The output of motor 201 drives the turntable 202, which is fixedly connected to it, to rotate. Since the rotating shaft 203 is fixedly connected to the right side of the outer wall of turntable 202, the rotating shaft 203 also rotates with turntable 202. The rotating shaft 203 is slidably connected to the middle of the inner wall of adjusting rod 204, which converts the rotation of the rotating shaft 203 into pushing and pulling forces on adjusting rod 204. Bolt 205 is threadedly connected to the rear side of the inner wall of circuit breaker 1, and adjusting rod 204 is rotatably connected to the outer wall of bolt 205. Bolt 205 acts as a support for the rotation of adjusting rod 204. When the rotating shaft 203 makes a circular motion and pushes the adjusting rod 204, the adjusting rod 204 will swing around the bolt 205 at a certain angle. The front side of the outer wall of the adjusting rod 204 has an arc-shaped groove 206. The switch 3 is slidably connected to the middle of the inner wall of the arc-shaped groove 206. When the adjusting rod 204 swings around the bolt 205, the arc-shaped groove 206 will move accordingly, thereby driving the switch 3 to slide up and down in the arc-shaped groove 206, thereby realizing the opening or closing action of the switch 3. The whole process is driven by the motor 201, realizing the automatic control of the swing of the switch 3. There is no need for manual operation of the switch 3. This not only improves the accuracy and timeliness of operation, but also avoids the risk of electric shock and mechanical injury that may be faced during manual operation. It is suitable for some dangerous environments or scenarios that require frequent operation of the switch 3.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
