Description

Technical Field

[0001] This invention relates to the field of circuit protector technology, specifically to a remotely monitorable fuse. Background Technology

[0002] As an important overcurrent protection component in circuit systems, fuses are widely used in power transmission, industrial equipment, and household appliances. Their core function is to disconnect the circuit by melting the internal fusible element when an abnormal current such as overload or short circuit occurs in the circuit, thus preventing damage to downstream equipment caused by the abnormal current.

[0003] Existing fuses typically include basic structures such as fuse holder, contact holder, and fuse element. The contact holder is used to realize the electrical connection between the fuse and the external circuit, while the fuse holder provides installation support for each component. The overall design mainly meets the basic fuse protection function. Although some products are equipped with simple current monitoring elements, a complete status monitoring and remote feedback system has not yet been formed.

[0004] Traditional fuses typically have a single metal wire or sheet structure for the fuse element. When the fuse breaks, it relies solely on its own fracture to disconnect the circuit. However, the electric arc generated during a circuit fault can easily create a conductive path between the broken ends of the fuse element. This causes the broken fuse element to re-contact under the influence of the arc, resulting in secondary conduction. This secondary conduction not only renders the fuse ineffective but also causes the fuse sleeve to burn out and the fuse holder to deform due to the continued burning of the arc. It can even further expand the fault area, causing safety hazards such as localized fires in the circuit system and permanent damage to equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a remotely monitored fuse, which solves the problem that when the fuse breaks, it only breaks on its own to interrupt the current, but the electric arc generated by the circuit fault at that moment can easily cause the two ends of the broken fuse to form a conductive channel, leading to secondary conduction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a remotely monitorable fuse, comprising a fuse holder, with fitting grooves on both the left and right sides of the top of the fuse holder, and a clamping ring disposed within the fitting grooves; contact plates are disposed on both the left and right sides of the top of the fuse holder, and compression plates are fixedly connected to the front and rear sides of two adjacent contact plates; the two ends of the clamping ring respectively contact the corresponding compression plates; a support block is disposed on the top of each contact plate; a pressure plate is disposed on the bottom of each contact plate; a seat groove is disposed at the bottom of the fuse holder, and a monitoring processor is fixedly connected within the seat groove; a current sensor is disposed on the left side of the monitoring processor, and a voltage sensor is disposed on the right side of the monitoring processor; and a fuse is disposed between the four compression plates.

[0007] By adopting the above technical solutions, the fuse is designed to avoid secondary conduction caused by re-contact due to electric arcing, thereby improving the reliability of fuse protection, preventing the expansion of faults and potential safety hazards, and ensuring the stable and safe operation of the circuit system. At the same time, the monitoring processor monitors and organizes data from various sensors and sends it to the monitoring platform, enabling real-time monitoring of the fuse's working status and timely detection of fuse faults without on-site supervision, which greatly reduces the cost of manual inspection and the time required for troubleshooting.

[0008] Preferably, the fuse includes two engaging blocks, each of which contacts two adjacent extrusion plates. A fuse sleeve is fitted between the two engaging blocks, and a fusible strip is provided between the two engaging blocks. Two connecting pieces are engaged on the surface of the fusible strip, and two elastic metal pieces are fixedly connected between the two connecting pieces.

[0009] By adopting the above technical solutions, the close contact between the locking block and the extrusion piece can ensure the stable conductivity of the fuse and the contact base. The fuse sleeve can isolate the internal fusible strip from external dust and moisture, extending the service life of the fusible strip. The elastic metal sheet can quickly release stress when the fusible strip melts, further pulling the two ends of the broken fusible strip apart, avoiding secondary conduction caused by electric arc, and improving the protection reliability of the fuse.

[0010] Preferably, a plurality of fastening bolts are provided in the seat groove, and two adjacent fastening bolts pass through the pressure plate and are threadedly connected to the support block.

[0011] By adopting the above technical solution, when the fastening bolts are tightened, the pressure plate and the support block can be driven to move closer to each other, thereby forming a clamping force in the vertical direction on the contact seat, firmly fixing the contact seat on the fuse seat, preventing the contact seat from shifting due to equipment vibration, current surge and other factors during the operation of the fuse, and ensuring the continuity of the circuit connection.

[0012] Preferably, two longitudinal limiting grooves are provided on both sides of the bottom of the two contact bases, and several transverse limiting grooves are provided at the center of the bottom of the two contact bases.

[0013] By adopting the above technical solution, the longitudinal limiting groove and the transverse limiting groove can serve as guide rails for adjusting the position of the contact seat. This not only prevents the contact seat from shifting or tilting during adjustment, but also provides multiple fixed positions for the contact seat, adapting to fuses of different lengths and improving the versatility of the equipment.

[0014] Preferably, the two fastening bolts in the middle pass through the current sensor and the voltage sensor respectively.

[0015] Preferably, two placement slots are provided at the center of the top of the fuse holder. An arc sensor is installed inside the left placement slot, and an acoustic sensor is installed inside the right placement slot.

[0016] Preferably, the arc sensor, acoustic sensor, current sensor, and voltage sensor are all electrically connected to the monitoring processor.

[0017] Preferably, a number of limiting blocks are fixedly connected to the top left and right sides of the fuse holder, and the lateral limiting blocks are in contact with the longitudinal limiting groove, while the longitudinal limiting blocks are in contact with the lateral limiting groove.

[0018] Preferably, the monitoring processor includes a signal receiving submodule, a signal conditioning submodule, an analog-to-digital conversion submodule, and a temporary storage submodule;

[0019] When a fuse blows, the arc sensor, acoustic sensor, current sensor, and voltage sensor are electrically connected to transmit the collected arc intensity signal, abnormal acoustic signal, loop current signal, and voltage signal to the signal receiving submodule in real time.

[0020] The signal receiving submodule transmits the received multiple analog signals to the signal conditioning submodule, which performs filtering, amplitude amplification and baseline calibration on the analog signals to obtain the processed analog signals.

[0021] The processed analog signal is transmitted to the analog-to-digital conversion submodule, which converts the analog signal into a standardized digital signal. The standardized digital signal is then transmitted to the temporary storage submodule for caching.

[0022] By adopting the above technical solution, the original analog signal when the fuse blows can be purified, amplified, and converted. The noise generated by external electromagnetic interference can be filtered out, the weak signal can be amplified to a recognizable range, and converted into a standardized digital signal that is easy for the monitoring processor to analyze. The temporary storage submodule can prevent the signal from being lost during transmission, ensure that the key monitoring data at the moment of fuse blowing is completely preserved, and provide a guarantee for subsequent data storage and remote transmission.

[0023] Preferably, the monitoring processor further includes a historical storage submodule and a remote communication submodule;

[0024] The standardized digital signals cached by the temporary storage submodule are transmitted to the historical storage submodule for storage. The remote communication submodule retrieves the currently stored data and the previous historical data from the historical storage submodule and sends both types of data to the remote monitoring platform to achieve real-time monitoring.

[0025] The historical storage submodule stores data in a format that combines timestamps and signal types.

[0026] By adopting the above technical solution, the historical storage submodule stores data in the format of timestamp and signal type, which facilitates subsequent tracing of the fuse operating status at different time points; the remote communication submodule compares and transmits the current data with the previous data, enabling the remote monitoring platform to quickly identify data change trends, promptly detect abnormal fuse status, and avoid the accidental errors of single data transmission, thereby improving the accuracy and reliability of remote monitoring.

[0027] Working principle: Adjust the position of the contact seat on the fuse holder according to the size of the fuse. When adjusting the position of the contact seat, the longitudinal limiting groove, the transverse limiting groove and the limiting block make contact to limit the position. After the adjustment is completed, tighten the four fastening bolts so that the support block squeezes and fixes the contact seat and the clamping ring. Then, the fuse is clamped between the four compression plates.

[0028] When used in a fuse, the fuse strip breaks from the center when it melts. At the same time as the fuse melts, the stress on the two elastic metal pieces is released, which makes the broken fuse strip farther apart.

[0029] After confirming the power is off, remove the fuse from the four compression tabs. After removing it, pull out the two locking blocks from the left and right sides of the fuse sleeve respectively. After pulling them out, pull the fuse strip out from the two locking blocks. Insert the new fuse strip and then insert the connecting piece from one side of the fuse strip. After both connecting pieces are locked on the fuse strip, reinsert them into the two locking blocks and then reinsert the two locking blocks from one side of the fuse sleeve.

[0030] This invention provides a remotely monitorable fuse. It has the following advantages:

[0031] 1. This invention employs a fuse structure with a surface-locking connecting piece for the fusible strip and a fixed elastic metal piece between the connecting pieces. When the fusible strip melts, the elastic metal piece releases stress and further pulls the two ends of the broken fusible strip apart, preventing the broken fusible strip from re-contacting due to the electric arc and forming secondary conduction. This achieves the effect of improving the reliability of fuse protection, preventing the expansion of faults and the occurrence of safety hazards, and ensuring the stable and safe operation of the circuit system.

[0032] 2. This invention employs a remote monitoring structure that integrates an arc sensor, an acoustic sensor, a current sensor, a voltage sensor, and a monitoring processor. It is also equipped with a historical storage submodule and a remote communication submodule. Because it can collect arc, acoustic, current, and voltage signals of the fuse in real time from multiple dimensions, and can remotely transmit the monitoring data to the monitoring platform, it achieves the effect of real-time monitoring of the fuse's working status and timely detection of fuse faults without on-site supervision, which greatly reduces the cost of manual inspection and the time for troubleshooting.

[0033] 3. This invention utilizes the bidirectional limiting action of the limiting block and the longitudinal and transverse limiting grooves when adjusting the position of the contact base. At the same time, it uses fastening bolts to pass through the pressure plate and support block and simultaneously fix the current sensor and voltage sensor. This allows for precise adjustment of the contact base spacing to adapt to different specifications of fuses, and ensures the stability of the contact base and sensor position during operation. Therefore, it improves the equipment's adaptability to different specifications of fuses, ensures the operational stability of each component, and enhances the practical value and long-term operational reliability of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a remotely monitored fuse, including a fuse base 1. The fuse base 1 has fitting grooves 10 on both the left and right sides of its top. A clamping ring 4 is disposed within each fitting groove 10. A contact base 2 is disposed on both the left and right sides of the top of the fuse base 1. An extrusion piece 5 is fixedly connected to the front and rear sides of two adjacent contact bases 2. The two ends of the clamping ring 4 contact the corresponding extrusion piece 5. A support block 6 is disposed on the top of each contact base 2. A pressure plate 12 is disposed at the bottom of each contact base 2. A seat groove 14 is disposed at the bottom of the fuse base 1. A monitoring processor 16 is fixedly connected within the seat groove 14. A current sensor 15 is disposed on the left side of the monitoring processor 16, and a voltage sensor 17 is disposed on the right side of the monitoring processor 16. A fuse 3 is disposed between the four extrusion pieces 5.

[0045] Specifically, the clamp 4 is an elastic metal ring with arc-shaped contact heads integrally formed at both ends. The arc-shaped contact heads fit against the outer wall of the extrusion sheet 5. The extrusion sheet 5 is a copper elastic sheet with an inwardly inclined arc structure in its natural state, which can form an elastic clamp with the outer wall of the fuse 3. The support block 6 and the pressure plate 12 are both made of metal. The top of the pressure plate 12 fits tightly against the bottom of the contact seat 2, forming a clamping limit on the contact seat 2 in the vertical direction. The monitoring processor 16 is fixed at the top of the seat groove 14. The current sensor 15 and the voltage sensor 17 are fixed on the left and right sides of the monitoring processor 16, respectively, and can directly collect the current and voltage signals of the fuse 3.

[0046] The fuse 3 includes two engaging blocks 301, which are in contact with two adjacent extrusion plates 5 respectively. A fuse sleeve 302 is sleeved between the two engaging blocks 301. A fusible strip 303 is provided between the two engaging blocks 301. Two connecting pieces 305 are engaged on the surface of the fusible strip 303. Two elastic metal pieces 304 are fixedly connected between the two connecting pieces 305.

[0047] Specifically, the locking block 301 is a copper strip block. Each of the two locking blocks 301 has a slot on one side that matches the extrusion piece 5. The extrusion piece 5 can be embedded in the slot to form a tight contact, ensuring conductivity. The inner wall of the fuse sleeve 302 is interference-fitted with the outer wall of the locking block 301, which can form a sealed protection for the internal melt strip 303. Both ends of the melt strip 303 are inserted into the slots of the locking block 301. The connecting piece 305 can be clamped on the surface of the melt strip 303. The two connecting pieces 305 are symmetrically distributed on both sides of the middle of the melt strip 303. The elastic metal piece 304 has a V-shaped structure. Its two ends are inserted into the outer walls of the two connecting pieces 305 respectively. It is in a slightly stretched state in its natural state. When the melt strip 303 breaks, it can quickly contract to release stress. The connecting piece is made of polypropylene.

[0048] Several fastening bolts 11 are provided in the seat groove 14. Two adjacent fastening bolts 11 pass through the pressure plate 12 and are threadedly connected to the support block 6.

[0049] Specifically, the fastening bolts 11 are made of stainless steel, and there are four of them arranged in a row in the seat groove 14. The pressure plate 12 has through holes that are compatible with the fastening bolts 11. The bottom of the support block 6 has holes that are compatible with the fastening bolts 11, and the inner diameter of the holes is slightly larger than the outer diameter of the fastening bolts 11. When the fastening bolts 11 are tightened, the support block 6 and the fastening bolts 11 move with threads, fixing the support block 6, the contact seat 2, the pressure plate 12 and the clamp 4 on the fuse seat 1.

[0050] Two longitudinal limiting grooves 18 are provided on both sides of the bottom of the two contact bases 2, and several transverse limiting grooves 19 are provided at the center of the bottom of the two contact bases 2.

[0051] Specifically, the length direction of the longitudinal limiting groove 18 is consistent with the longitudinal direction of the contact base 2, the groove depth is adapted to the height of the limiting block 13, and the transverse limiting groove 19 is between the two longitudinal limiting grooves 18.

[0052] The two fastening bolts 11 in the middle pass through the current sensor 15 and the voltage sensor 17 respectively.

[0053] Specifically, both the current sensor 15 and the voltage sensor 17 have positioning holes on their housings that are adapted to the fastening bolt 11. The inner diameter of the positioning hole is clearance-fitted with the outer diameter of the fastening bolt 11. When the fastening bolt 11 passes through the positioning hole, the outer wall of the fastening bolt 11 does not contact the inner wall of the positioning hole, thus avoiding the bolt's conductivity from interfering with the sensor.

[0054] Two placement slots 7 are provided at the top center of the fuse holder 1. An arc sensor 8 is installed inside the left placement slot 7, and an acoustic sensor 9 is installed inside the right placement slot 7.

[0055] Specifically, both the arc sensor 8 and the acoustic sensor 9 are fixed in the placement slot 7. The detection lens of the arc sensor 8 faces the middle of the fuse 3, and a transparent high-temperature resistant glass cover is provided on the outside of the lens to prevent high-temperature debris generated when the fuse melts from damaging the lens. The pickup end of the acoustic sensor 9 faces the middle of the fuse 3, and a metal dustproof mesh is provided on the outside of the pickup end to filter dust without affecting the acquisition of sound signals. The distance between the two placement slots 7 is adapted to the length of the fuse 3 to ensure that the sensor can accurately capture the arc light and sound signals when the fuse melts.

[0056] Arc sensor 8, acoustic sensor 9, current sensor 15 and voltage sensor 17 are all electrically connected to monitoring processor 16.

[0057] Specifically, all four sensors are connected to the monitoring processor 16 via shielded wires. The outer layer of the shielded wires is wrapped with a metal shielding mesh to prevent external electromagnetic interference from affecting signal transmission. The output of the arc light sensor 8 is connected to the arc light signal interface of the monitoring processor 16, which can transmit the collected light intensity analog signal to the processor. The output of the acoustic sensor 9 is connected to the acoustic signal interface of the monitoring processor 16, which can transmit the collected sound analog signal to the processor. The output of the current sensor 15 is connected to the current signal interface of the monitoring processor 16, which collects and transmits the circuit current signal through the principle of electromagnetic induction. The output of the voltage sensor 17 is connected to the voltage signal interface of the monitoring processor 16, which collects and transmits the circuit voltage signal through the principle of voltage division. The power supply terminals of all four sensors are connected to the power supply module of the monitoring processor 16, which provides a stable voltage.

[0058] Several limiting blocks 13 are fixedly connected to the top left and right sides of the fuse holder 1. The horizontal limiting blocks 13 are in contact with the vertical limiting groove 18, and the vertical limiting blocks 13 are in contact with the horizontal limiting groove 19.

[0059] The monitoring processor 16 includes a signal receiving submodule, a signal conditioning submodule, an analog-to-digital conversion submodule, and a temporary storage submodule;

[0060] When a fuse blows, the arc sensor 8, acoustic sensor 9, current sensor 15 and voltage sensor 17 are electrically connected to transmit the collected arc intensity signal, abnormal acoustic signal, loop current signal and voltage signal to the signal receiving submodule in real time.

[0061] The signal receiving submodule transmits the received multiple analog signals to the signal conditioning submodule. The signal conditioning submodule performs filtering, amplitude amplification and baseline calibration on the analog signals to obtain the processed analog signals.

[0062] The processed analog signal is transmitted to the analog-to-digital conversion submodule, which converts the analog signal into a standardized digital signal. The standardized digital signal is then transmitted to the temporary storage submodule for caching.

[0063] Specifically, the signal receiving submodule uses a multi-channel signal receiver with four independent signal receiving channels, each corresponding to the signal input of four sensors. It can simultaneously receive multiple analog signals, and each channel is equipped with a signal detection circuit that can automatically issue a fault prompt when the signal is interrupted. The signal conditioning submodule includes a low-pass filter, a signal amplifier, and a baseline calibration circuit. The signal amplifier uses an operational amplifier, which can amplify weak signals by 10-100 times. The baseline calibration circuit adjusts the signal baseline to a uniform standard through a built-in reference voltage source, ensuring that the signals from different sensors are at the same reference level.

[0064] The monitoring processor 16 also includes a historical storage submodule and a remote communication submodule;

[0065] The standardized digital signals cached by the temporary storage submodule are transmitted to the historical storage submodule for storage. The remote communication submodule retrieves the currently stored data and the previous historical data from the historical storage submodule and sends both types of data to the remote monitoring platform to achieve real-time monitoring.

[0066] The history storage submodule stores data in the format of timestamp and signal type.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
