Description

Technical Field

[0001] The invention relates to the technical field of power equipment, in particular to a fully sealed 10kV metering cabinet with a multiple protection structure. Background Art

[0002] The fully sealed 10kV metering cabinet is widely used in high-voltage power systems and is a highly reliable electric energy metering device. Its cabinet body effectively isolates the influence of the external environment on the internal components through a fully enclosed structure. The SF6 gas filled inside is used as an insulating medium to prevent moisture, dust and small animals from interfering with the operation of the equipment. It is particularly suitable for harsh environments such as high humidity and heavy salt fog.

[0003] The multi-protection structure is a way to ensure the safety and stability of the equipment during operation through multi-level and multi-dimensional protection measures; its core is to prevent easy failures, misoperation or external interference from different angles through the cooperation of multiple protection mechanisms, so as to maximize the reliability of the equipment and the safety of operation. This protection is not only aimed at the influence of the external environment, but also includes the prevention and control of problems that are prone to occur inside the equipment; the significance of multiple protection is that it can form a comprehensive safety protection system. When a single problem occurs, it can avoid the expansion of accidents through other levels of protection, ensuring that the equipment can still operate stably even in complex or harsh environments.

[0004] The existing 10kV metering cabinets have exposed some significant deficiencies in long-term operation, mainly focusing on insulation performance, sealing durability, seismic resistance and maintenance requirements. First of all, the long-term reliability of insulation performance is low. As the equipment ages, the internal insulation materials tend to age gradually, and the SF6 gas, as the main insulating medium, tends to lose its effective insulation effect due to leakage or pressure drop. This situation will greatly increase the short circuit, especially in high-voltage environments. Short circuits will cause serious equipment failures and even fire risks, threatening the safety and stability of the power system. In addition, the seismic resistance of the mechanical structure is also significantly limited. When the equipment is subjected to external vibration or internal electrodynamic shock, the cabinet structure and internal components are prone to loosening or deformation. This will not only affect the normal operation of the equipment, but also cause more serious problems such as component shedding and poor line contact, thus burying potential safety hazards. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a fully sealed 10kV meter cabinet with a multiple protection structure, which solves the problems of the existing 10kV meter cabinet having degraded insulation performance during long-term operation, which leads to easy fire and limited earthquake resistance, and easily causes short circuit, equipment failure and safety hazards.

[0042] The circuit line 6 first passes through the dustproof shell 8 and then enters the interior of the cabinet 1, and the snap-in terminal 14 can conveniently connect or disconnect the circuit line 6. When the turntable 20 rotates, it can conveniently drive the connecting metal sheet 21 to move. When the connecting metal sheet 21 and the snap-in terminal 14 are snapped, the circuit line 6 will be connected, and when the connecting metal sheet 21 and the snap-in terminal 14 are separated, the circuit line 6 will be disconnected, so that the circuit can be conveniently disconnected in the event of fire or other faults, thereby improving the overall safety of the metering cabinet.

[0045] Please see attached Figure 7 and attached Figure 8 The buffer assembly includes a buffer plate 25, which is slidably connected to the middle part of the placement plate 7, a buffer top shell 26 and a spring 28 are fixedly connected to the bottom of the buffer plate 25, a buffer bottom shell 27 is fixedly connected to the middle part of the placement plate 7, one end of the spring 28 is fixedly connected to a buffer top plate 29, a buffer column 30 is fixedly connected to the bottom of the buffer top plate 29, and a reset assembly is provided at the bottom of the buffer column 30, which is used to eject the buffer column 30 upward.

[0046] When vibration occurs, the buffer plate 25 will squeeze the buffer top shell 26 and the spring 28, and when the spring 28 is squeezed, it will drive the buffer top plate 29 to move downward, and when the buffer top plate 29 moves downward, it will squeeze the buffer column 30. At the same time, under the action of the spring 28, the buffer plate 25 can be easily ejected and reset upward.

[0047] Please see attached Figure 8 The reset assembly includes a buffer bottom plate 31, which is fixedly connected to the bottom of the buffer column 30. A spring three 32 is fixedly connected to the bottom of the buffer bottom plate 31, and one end of the spring three 32 away from the buffer bottom plate 31 is fixedly connected to the middle of the buffer bottom shell 27.

[0048] When the buffer column 30 moves downward, it will squeeze the buffer bottom plate 31, and when the buffer bottom plate 31 moves downward, it can squeeze the spring three 32, so that under the action of the spring three 32 and the spring two 28, the vibration force can be easily buffered, thereby avoiding external vibration force from causing damage to the electronic components inside the cabinet 1.

[0049] Please see attached Fig. 9 , the monitoring system includes:

[0050] A monitoring module, which is used to monitor the status inside the system in real time, detect fire or faults and send signals;

[0051] The signal processing module receives and analyzes the signals transmitted by the monitoring module, determines the equipment status and issues control instructions;

[0052] The execution module performs operations according to the instructions of the signal processing module, such as disconnecting the magnetic attraction, triggering the circuit to disconnect, or starting an alarm.

[0053] The monitoring module can accurately capture subtle changes in the environment. Once an abnormal situation is detected, such as a sudden temperature rise, excessive smoke concentration or abnormal current, the monitoring module will immediately convert these abnormal information into electrical signals and quickly transmit them to the signal processing module.

[0054] The signal processing module is the "brain" of the system, responsible for receiving and deeply analyzing the signals transmitted by the monitoring module. It decodes and evaluates the signals through preset algorithms and logical judgments to accurately determine the current status of the equipment. For example, the signal processing module can identify whether it is a simple temperature fluctuation or a potential fire risk, a normal fluctuation in the circuit or a precursor to a fault. Based on these analysis results, the signal processing module will generate corresponding control instructions to deal with different emergency situations.

[0055] Finally, the execution module, as the "executor" of the system, performs specific operations according to the control instructions issued by the signal processing module. These operations may include disconnecting the magnetic attraction to release the safety door, triggering the circuit disconnection to cut off the power supply, or activating the alarm system to sound and light alarms. Through this series of linkage reactions, the system can respond effectively to fires or equipment failures in the first time, and maximize the safety of personnel and property.

[0056] Please see attached Fig. 9 , the monitoring modules include:

[0057] A temperature sensing unit is used to monitor temperature changes inside the device. When the temperature exceeds a safety threshold, an alarm signal is triggered, indicating the risk of overheating or fire.

[0058] Image sensing unit, which is used to collect image information inside the equipment in real time, detect fire, smoke or equipment abnormality, and identify faults or danger signals by analyzing image changes;

[0059] The current monitoring unit is used to monitor the current value of the internal circuit of the equipment and identify electrical faults such as overcurrent, short circuit or overload.

[0060] The temperature sensing unit is like a "thermometer" for the monitoring system, which is specially used to monitor the temperature changes inside the equipment; it collects temperature data of key parts of the equipment in real time and compares it with the preset safety threshold. Once it detects that the temperature exceeds the safety range, the temperature sensing unit will immediately trigger an alarm signal and send an early warning to the system, indicating the risk of overheating or fire, thereby buying precious time for timely response measures.

[0061] The image sensing unit acts as the "eyes" of the monitoring system, responsible for collecting image information inside the device in real time. Through high-definition cameras and image processing technology, the image sensing unit can clearly capture subtle changes inside the device, such as flames, smoke or other abnormal conditions. The system will identify potential fire, smoke or abnormal equipment signals by performing real-time analysis and comparison of the collected images. Once abnormal image features are found, the image sensing unit will quickly pass the information to the signal processing module for further confirmation and processing.

[0062] The current monitoring unit is the "current steward" of the monitoring system, focusing on monitoring the current value of the internal circuit of the equipment; the current monitoring unit can monitor the current changes in the circuit in real time and identify electrical faults such as overcurrent, short circuit or overload. These electrical faults are often the cause of equipment damage and fire accidents, so the role of the current monitoring unit is crucial. Once an abnormal current is detected, the current monitoring unit will immediately issue an alarm, prompting the system to take corresponding protective measures, such as cutting off the power supply or starting the backup circuit to prevent the fault from expanding and accidents from occurring.

[0063] Please see attached Fig. 9 , the signal processing module includes:

[0064] The signal receiving unit is used to receive various signals transmitted by the monitoring module, such as temperature, smoke, current, image, etc., to ensure that all detection data can smoothly enter the signal processing process;

[0065] A signal decoding unit, which is used to decode and format the received original signal and convert it into standardized data that can be recognized and analyzed by the system;

[0066] The signal analysis unit is used to perform comprehensive analysis on the received signals, identify abnormal signals such as overheating, excessive smoke concentration, current overload, etc., and determine the type, severity and location of the abnormality.

[0067] The signal receiving unit is like the "information entrance" of the monitoring system, responsible for receiving various signals transmitted from the monitoring module, including temperature, smoke, current, image and other types of data. The signal receiving unit ensures that all detection data can enter the signal processing process smoothly and without omission through an efficient data receiving mechanism, providing a solid data foundation for subsequent analysis and processing.

[0068] The signal decoding unit acts as the "translator" of the monitoring system. Its task is to decode and format the received raw signals. Since the signals transmitted by the monitoring module are in various formats and encoding methods, the signal decoding unit needs to convert these complex raw signals into standardized data that the system can recognize and analyze. Through decoding and formatting, the signal decoding unit not only improves the availability of data, but also provides a unified data format for subsequent signal analysis, ensuring the accuracy and efficiency of the analysis.

[0069] The signal analysis unit is the "think tank" of the system, responsible for comprehensive analysis of the received standardized signals; it uses preset algorithms and logical judgments to conduct in-depth mining and comparison of various signals, aiming to identify abnormal signals, such as overheating, excessive smoke concentration, current overload, etc. In addition, the signal analysis unit can further determine the type, severity and specific location of these abnormalities, and provide the system with detailed abnormality reports. Based on these analysis results, the system can issue early warnings in a timely manner and formulate corresponding response measures, thereby effectively preventing and dealing with potential safety risks.

[0070] Please see attached Figure 2 and attached Figure 3 A flash light 9 is fixedly connected to the upper and lower sides of the dustproof shell 8, a buzzer 10 is fixedly connected to the middle of the dustproof shell 8, a control panel 5 is fixedly connected to the side of the cabinet 1 away from the cabinet door 2, and a display panel 3 is fixedly connected to one side of the cabinet door 2, which is used to observe the working status of the cabinet 1 in real time.

[0071] When a fault or fire occurs, the controller 11 will control the flash light 9 and the buzzer 10 to flash and sound an alarm, thereby conveniently reminding the operator to perform maintenance or escape. The control panel 5 can facilitate the operator to control the overall operation of the metering cabinet, and the display panel 3 can facilitate the operator to observe the working conditions inside the cabinet 1 in real time.

[0072] Working principle: When a fault or fire occurs inside the cabinet 1, the image sensor 12 will detect it. After detecting the fault, the image sensor 12 will transmit the detected message to the inside of the controller 11. When the controller 11 receives the signal, it will analyze and judge, and thus control the electromagnet 18 to disconnect the magnetic attraction. When the electromagnet 18 disconnects the magnetic attraction, the magnet block 19 can be pushed out to the opposite side under the action of the spring 23 and the telescopic rod 24. When the magnet block 19 is pushed out, it will drive the connecting metal sheet 21 to move through the movable rod 33, so that the connecting metal sheet 21 can be separated from the card terminal 14. When the connecting metal sheet 21 is separated from the telescopic rod 24, the circuit can be disconnected in the event of a fire or other faults. At the same time, the controller 11 will control the flash 9 and the buzzer 10 to work.

[0073] When buffering the electronic components inside the cabinet 1, the buffer plate 25 will squeeze the buffer top shell 26 and the spring two 28. When the spring two 28 is squeezed, it will drive the buffer top plate 29 to move downward. When the buffer top plate 29 moves downward, it will squeeze the buffer bottom plate 31 through the buffer column 30. When the buffer bottom plate 31 is squeezed, it will move downward and squeeze the spring three 32. Under the action of the spring three 32 and the spring two 28, the external vibration force can be buffered.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
