Description

Technical Field

[0001] This application relates to the field of power transmission, and in particular to a busbar trunking quick-connect power supply equipment and power supply method. Background Technology

[0002] In the field of power transmission, busbar trunking, as a highly efficient power distribution and transmission device, is widely used in numerous scenarios, including industrial, commercial, and civil buildings. With the continuous growth of electricity demand and the increasing number of electrical devices, higher requirements are being placed on the connection efficiency and power supply reliability of busbar trunking. Busbar trunking can safely and stably distribute electrical energy to various electrical terminals, and its performance directly affects the operational quality of the entire power system, playing a crucial role in ensuring normal power supply for production and daily life.

[0003] In traditional busbar trunking power supply technology, the common method for connecting busbar trunking and transmitting power is to directly butt the busbar trunking together and fix it using mechanical means such as bolts, and then directly connect the conductive busbars. This method can meet basic power supply needs to a certain extent, but it is cumbersome to operate and requires a lot of time and manpower. Another method is to set up an adapter at the connection point of the busbar trunking to connect the conductive busbars through the adapter. This adapter is often complex in structure, and its installation and maintenance are difficult. In addition, some technologies use simple connectors to connect the busbar trunking, but these connectors have poor conductivity and stability and are prone to problems such as poor contact.

[0004] Existing busbar trunking connection power supply technology has obvious defects. Traditional connection methods are complicated to operate, resulting in low connection efficiency and making it difficult to meet the needs when the power system needs to be built or adjusted quickly. Some transfer devices and simple connectors have problems such as complex structure, poor conductivity and stability, which can easily lead to faults such as poor contact and overheating, affecting the reliability and safety of power supply and failing to meet the requirements of modern power systems for efficient and stable power supply. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this application provides a method for quickly connecting power supply equipment and power supply to busbar trunking, which can realize rapid connection and fault line replacement of busbar trunking without interrupting power supply, significantly improving the reliability and maintainability of the power supply system.

[0006] This application is achieved through the following technical solution:

[0007] A busbar trunking system for quick connection to power supply equipment includes:

[0008] A busbar connection box includes a box body, a sealed chamber is formed in the middle of the box body, and a busbar trough is provided on the side wall of the box body;

[0009] A plurality of conductive busbars are arranged side by side in the busbar groove, and the inner end of each conductive busbar extends into the sealed chamber and forms a right-angle bend; each right-angle bend is parallel to the thickness direction of the conductive busbar, and each right-angle bend is staggered along the side-by-side direction of the conductive busbars, so that the right-angle bends of adjacent conductive busbars form a symmetrical staggered interval;

[0010] A female connector assembly is fixed to the side wall of the housing and electrically connected to the right-angle bend of each of the conductive busbars; wherein at least two female connector assemblies are connected in parallel on the same conductive busbar.

[0011] The connecting cable has male connectors at both ends that mate with the female connector assembly, for connecting two adjacent busbar trunking boxes to achieve electrical transmission.

[0012] By adopting the above technical solution, a sealed chamber is formed in the middle of the busbar connection box, providing a stable and safe working environment for components such as the conductive busbars. This effectively prevents the entry of external dust and moisture, ensuring the normal operation and service life of the equipment. The right-angle bends of the conductive busbars are staggered, forming symmetrical staggered intervals, increasing the insulation distance between adjacent conductive busbars, reducing the risk of mutual interference and short circuits, and improving the safety and stability of power supply. At least two female connector assemblies are connected in parallel on the same conductive busbar, along with connecting cables with male connector assemblies at both ends, enabling flexible and reliable electrical transmission between adjacent busbar connection boxes. When one female connector assembly or connecting cable fails, the other female connector assemblies and connecting cables can continue to operate, ensuring the continuity of power supply. In addition, this multi-female connector assembly parallel design facilitates the installation, maintenance, and expansion of the equipment. The number and layout of connecting cables can be flexibly adjusted according to actual needs, improving the applicability and operability of the equipment and better meeting the power supply needs in different scenarios.

[0013] Optionally, a first connecting plate and a second connecting plate are fixed on the two wide surfaces of the right-angle bend, respectively; both the first connecting plate and the second connecting plate are L-shaped, including a connected vertical segment and a horizontal segment; the vertical segment is fixedly connected to the wide surface of the right-angle bend; the end of the horizontal segment of the first connecting plate is bent upward to form a first mounting part, and the end of the horizontal segment of the second connecting plate is bent downward to form a second mounting part; the female head assembly is provided on both the first mounting part and the second mounting part.

[0014] By adopting the above technical solution, L-shaped first and second connecting plates are fixed to the two wide faces of the right-angle bend, respectively, with their vertical sections connected to the wide faces, ensuring the stability of the connection. The horizontal end of the first connecting plate is bent upward to form the first mounting part, and the horizontal end of the second connecting plate is bent downward to form the second mounting part. This design increases the space and flexibility for installing the female connector assembly. Female connector assemblies are installed on the first and second mounting parts, allowing at least two female connector assemblies to be connected in parallel on the same conductor busbar, realizing a multi-channel electrical connection method. This not only improves the power supply reliability and stability of the busbar trunking for rapid connection of power supply equipment, but also ensures that other channels can continue to transmit power even if one connection channel fails, reducing the risk of power outages due to faults and providing a continuous and stable power supply for electrical equipment.

[0015] Optionally, the busbar trunking includes a housing covering the conductive busbar; a sealing plate is fixed to one end of the housing near the box body, and the sealing plate is detachably connected to the box body; a sealing block is provided at one end of the housing away from the box body, and a grounding connection plate is installed on the sealing block; the sealing block and the grounding connection plate together surround the outer periphery of the end of the conductive busbar, and an insulating seal is provided between the housing and the conductive busbar.

[0016] By adopting the above technical solution, the busbar trunking shell covers the conductive busbars, protecting them from damage caused by external impacts and friction. The edge sealing plate is detachably connected to the enclosure, facilitating the installation and removal of the busbar trunking and simplifying subsequent maintenance and repair. The edge sealing block and grounding connection plate together enclose the outer perimeter of the conductive busbar ends, enhancing the structural stability of the ends. Simultaneously, the insulating seal between the shell and the conductive busbars not only prevents leakage and ensures electrical safety but also prevents the ingress of moisture, dust, and other impurities, improving the equipment's waterproof and dustproof performance, extending the service life of the busbar trunking's quick-connect power supply equipment, and ensuring the stable operation of the entire power supply system.

[0017] Optionally, the housing is constructed by splicing two symmetrically arranged ribs and a flange plate connecting the two ribs; the flange plate has fixing grooves arranged along its length on both sides; the edge sealing block is fixed in the fixing groove, and a water-stop sealing strip is sandwiched between the edge sealing block and the groove wall of the fixing groove; the edge sealing plate is fixed to the end face of the flange plate by corner brackets.

[0018] By adopting the above technical solution, the busbar trunking shell is constructed from symmetrically arranged ribs and flanges. This structure facilitates assembly and improves production efficiency. The fixing grooves on both sides of the flanges are used to install edge sealing blocks. The water-stop sealing strip sandwiched between the edge sealing blocks and the groove walls effectively prevents moisture ingress, avoiding damage to the conductive busbars from moisture and improving the equipment's moisture resistance. The edge sealing plates are fixed to the flange end faces using angle brackets, making the structural connection more stable, enhancing the overall structural stability, ensuring reliable operation of the busbar trunking in various environments, and extending the equipment's service life.

[0019] Optionally, the edge sealing block is provided with positioning flanges on both sides, the positioning flanges being adapted to abut against the end of the fixing groove to achieve axial positioning; the edge sealing block is also provided with bosses extending along its length direction, and the ground wire connecting plate is symmetrically fixed on both sides of the bosses.

[0020] By adopting the above technical solution, the positioning flanges on both sides of the edge sealing block can abut against the end of the fixing groove for axial positioning. This ensures that the edge sealing block is accurately and stably positioned in the appropriate axial position during installation, avoiding positional deviation and guaranteeing the overall structural stability of the busbar trunking. Simultaneously, the protrusions extending along the length of the edge sealing block facilitate the symmetrical fixing of the grounding connection plate on both sides. This symmetrical fixing method makes the grounding connection more uniform and reliable, effectively improving grounding performance and ensuring electrical safety. Furthermore, this design facilitates operation during installation or maintenance, improving work efficiency and contributing to enhancing the overall quality and reliability of the busbar trunking's rapid connection to power supply equipment.

[0021] Optionally, the edge sealing block is provided with a snap-fit ​​groove, and the ground wire connection plate is provided with a right-angle snap-fit ​​edge that matches the snap-fit ​​groove.

[0022] By adopting the above technical solution, the snap-fit ​​groove and the right-angle snap-fit ​​edge can be matched to pre-compact the insulating seal between the housing and the conductive line during the assembly process of the ground wire connection plate, thereby improving the sealing performance. It also provides a supporting foundation for overcoming the reaction force of the insulating seal during the subsequent tightening process of the ground wire connection plate, which facilitates assembly.

[0023] Optionally, the conductive sleeve of the female connector assembly penetrates the first connecting plate or the second connecting plate, and a heat pipe is embedded in the conductive sleeve tail; the evaporation section of the heat pipe is located at the conductive sleeve tail; the condensation section of the heat pipe extends out of the conductive sleeve tail and makes thermal contact with the heat-conducting plate fixed to the inner wall of the box.

[0024] By adopting the above technical solution, a heat pipe is embedded in the tail of the conductive sleeve of the busbar assembly, with the evaporation section of the heat pipe located at the tail of the conductive sleeve. This effectively transfers the heat generated at the tail of the conductive sleeve. The condensation section of the heat pipe extends out of the tail of the conductive sleeve and makes thermal contact with the heat-conducting plate fixed to the inner wall of the housing, further transferring the heat to the heat-conducting plate. This structure greatly enhances the heat dissipation capacity of the busbar assembly, accelerates the heat dissipation rate at the tail of the conductive sleeve, reduces the operating temperature at the tail of the conductive sleeve, avoids increased power loss due to excessive temperature and avoids affecting the service life of the equipment, ensures the stable operation of the busbar trunking for rapid connection to power supply equipment, and improves the reliability and safety of the entire power supply system.

[0025] Optionally, the heat-conducting plate is provided with a plurality of insulating heat-conducting seats; the insulating heat-conducting seats are provided with insertion slots adapted to the condensation section of the heat pipe.

[0026] By adopting the above technical solution, the busbar trunking is connected to the box, and the conductive wires are arranged side by side in the busbar trunking. The inner ends extend to the sealed chamber to form right-angle bends. The right-angle bends are staggered along the direction of the parallel arrangement of the conductive wires. At least two female head assemblies are connected in parallel on the same conductive wire. The tail of the conductive sleeve of the female head assembly is embedded with a heat pipe. The evaporation section of the heat pipe extends from the tail of the conductive sleeve and the condensation section, and makes thermal contact with the heat-conducting plate fixed to the inner wall of the box. The heat-conducting plate is provided with several insulating heat-conducting seats and plug slots that are compatible with the condensation section of the heat pipe. This enables the positioning and installation of the condensation section of the heat pipe, allowing the heat pipe to better conduct the heat generated at the tail of the conductive sleeve of the female head assembly to the heat-conducting plate, thereby improving the heat dissipation efficiency of the female head assembly and ensuring the stable operation of the busbar trunking for rapid connection to power supply equipment.

[0027] Optionally, the housing is provided with several sets of thermometers. The sensing end of each set of thermometers is fixed on an insulating heat-conducting base corresponding to different female connectors connected in parallel with the same conductive busbar. The scale area of ​​the thermometer dial is divided into a cold state indication area, a safe operation area, a warning area, and a danger alarm area from low temperature to high temperature.

[0028] By adopting the above technical solution, several sets of thermometers are installed on the enclosure, and the sensing end of each thermometer is fixed on an insulating heat-conducting base corresponding to different female connector components connected in parallel with the same conductive busbar. This allows for accurate monitoring of the temperature of each female connector component. Since these female connector components are connected in parallel with the same conductive busbar, their operating status affects the power supply stability of the entire system. By acquiring their temperature data in real time through the thermometers, potential abnormal heating problems can be detected in a timely manner. Furthermore, the thermometer dial scale is divided sequentially along the direction of pointer deflection into a cold state indication area, a safe operation area, a warning area, and a danger alarm area, which can be identified by different colors. With its markings, this design allows operators to intuitively and quickly determine the operating status of the equipment. When the temperature is in the cold indicator zone, it indicates that the equipment may be inactive or under low load. Within the safe operating zone, the equipment operates normally. Once it enters the warning zone, operators need to monitor the equipment's operation and investigate any potential hazards. When the temperature reaches the danger alarm zone, immediate measures must be taken to prevent damage from overheating and potential safety accidents. This design, based on temperature zone divisions and color-coded markings, significantly improves the safety and reliability of the busbar trunking's rapid connection to power supply equipment and reduces the risk of equipment failure.

[0029] A method for quick connection of power supply via busbar trunking, employing any one of the aforementioned quick connection power supply devices via busbar trunking, specifically includes the following steps:

[0030] S1. At least two female connector assemblies are pre-installed on the corresponding conductive busbars of the first and second busbars that need to be interconnected;

[0031] S2. Provide at least two independent connecting cables, each of which has a male connector at both ends that matches the female connector assembly;

[0032] S3. Connect one end of at least two of the connecting cables to the female connector pre-installed on the same conductive busbar of the first busbar through male connectors, thereby forming a parallel electrical connection.

[0033] S4. Insert the other end of the connecting cable into the female connector pre-installed on the corresponding conductive busbar of the second busbar through the male connector assembly respectively;

[0034] S5. When it is determined that a fault has occurred in the current power supply circuit between the first busbar and the second busbar by monitoring the temperature difference of different female connector assemblies connected in parallel with the same conductive busbar, the male connector assemblies at both ends of the connecting cable corresponding to the faulty circuit are removed from the female connector assemblies and replaced.

[0035] S6. Maintain at least one working connection cable in a plugged-in state to continue transmitting electrical energy between the first busbar and the second busbar through the working connection cable.

[0036] By adopting the above technical solution, when connecting power supply to the busbar trunking, at least two female connector assemblies are pre-installed on the corresponding conductive busbars of the first and second busbar trunkings, and at least two connecting cables with matching male connector assemblies are prepared. One end of the connecting cable is inserted into the female connector assembly of the same conductive busbar in the first busbar trunking to form a parallel electrical connection, and the other end is inserted into the female connector assembly of the corresponding conductive busbar in the second busbar trunking, ensuring multiple redundant power supply circuits. When a fault is detected in the current power supply circuit, the male connector assemblies at both ends of the connecting cable corresponding to the faulty circuit can be quickly removed from the female connector assembly and replaced. At the same time, at least one normal connecting cable is kept plugged in, allowing seamless transmission of power between the first and second busbar trunkings, greatly improving the reliability and stability of the busbar trunking power supply. This avoids power outages caused by single circuit faults, reduces the risk of electrical system collapse, effectively ensures the continuous and stable operation of power equipment, and is suitable for places with high requirements for power supply continuity.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] This application simplifies the connection operation of busbar trunking by using a structure including a busbar trunking connection box, conductive busbars, busbar connectors, and connecting cables, thereby improving connection efficiency and meeting the needs of rapid construction or adjustment of power systems.

[0039] This application connects at least two female connector assemblies on the same conductive busbar and connects them to adjacent busbar trunking boxes via connecting cables, thus avoiding power supply disruptions due to problems at a single connection point and improving power supply reliability.

[0040] The heat pipe embedded in the tail of the conductive sleeve of the female connector assembly in this application makes thermal contact with the heat-conducting plate, which helps to conduct away the heat generated by the female connector assembly, reduce overheating failures, and ensure the safety and stability of power supply.

[0052] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0053] Reference Figures 1 to 3 This application discloses a busbar trunking quick-connect power supply device, comprising:

[0054] The busbar connection box includes a box body 1, a sealed chamber is formed in the middle of the box body 1, and a busbar trough 2 is provided on the side wall of the box body 1.

[0055] A number of conductive wires 21 are arranged side by side in the busbar trough 2. The inner end of each conductive wire 21 extends into the sealed chamber and forms a right-angle bend 211. Each right-angle bend 211 is parallel to the thickness direction of the conductive wire 21, and each right-angle bend 211 is staggered along the side-by-side direction of the conductive wires 21, so that the right-angle bends 211 of adjacent conductive wires 21 form a symmetrical staggered interval.

[0056] The female connector assembly 28 is fixed to the side wall of the housing 1 and electrically connected to the right-angle bend 211 of each conductive busbar 21; wherein, at least two female connector assemblies 28 are connected in parallel on the same conductive busbar 21.

[0057] The connecting cable 5 has male connectors 51 at both ends that mate with the female connector 28, for connecting two adjacent busbar trunking boxes to achieve electrical transmission.

[0058] Specifically, refer to Figures 1 to 3 The busbar trunking connection box includes a box body 1, a sealed chamber formed in the middle of the box body 1, and a busbar trunking 2 provided on the side wall of the box body 1. The box body 1 can be made of metal, such as stainless steel, which has good strength and protective performance, or it can be made of high-strength plastic to reduce weight and cost. The sealed chamber can prevent dust, moisture and other substances from entering, ensuring the normal operation of the internal components. The shape and size of the busbar trunking 2 can be designed according to actual needs.

[0059] Reference Figures 1 to 3 The connecting cable 5 has male connectors 51 at both ends that mate with the female connector 28, for connecting two adjacent busbar trunking boxes to achieve electrical transmission. The connecting cable 5 can be a flexible cable for easy installation and layout. The male connector 51 and the female connector 28 can be plugged in, which is simple and quick to operate. As a mature technology, the conductive pins of the male connector 51 and the conductive sleeves of the female connector 28 can be made of high-elasticity copper alloy material and are designed with redundant contact points. The outer shell of the male connector 51 can be provided with a rotating locking ring that mates with the threads or grooves of the outer shell of the female connector 28 to achieve mechanical locking after plugging in, ensuring stable electrical contact and resisting vibration and loosening.

[0060] Reference Figures 2 to 4 The female connector assembly 28 is fixed to the side wall of the housing 1 and electrically connected to the right-angle bend 211 of each conductive busbar 21; at least two female connector assemblies 28 are connected in parallel on the same conductive busbar 21. This arrangement can improve the reliability of power supply. When one female connector assembly 28 fails, the other female connector assembly 28 can still ensure the transmission of power.

[0061] Reference Figures 2 to 4Several conductive busbars 21 are arranged side-by-side in the busbar trough 2. The inner end of each conductive busbar 21 extends into the sealed chamber and forms a right-angle bend 211. The conductive busbars 21 are usually made of materials with good conductivity, such as copper or aluminum. Each right-angle bend 211 is parallel to the thickness direction of the conductive busbar 21, and the right-angle bends 211 are staggered along the side-by-side direction of the conductive busbars 21, so that the right-angle bends 211 of adjacent conductive busbars 21 form a symmetrical staggered interval. This arrangement can increase the insulation distance between the conductive busbars 21, reduce mutual interference, and improve the safety of power transmission. A first connecting plate 2 is fixed on each of the two wide surfaces of the right-angle bend 211. 6. The first connecting plate 26 and the second connecting plate 27 are both L-shaped, including a connected vertical section and a horizontal section. The vertical section is fixedly connected to the wide surface of the right-angle bend 211, and the fixing method can be bolt connection, etc. The end of the horizontal section of the first connecting plate 26 is bent upward to form a first mounting part, and the end of the horizontal section of the second connecting plate 27 is bent downward to form a second mounting part. Both the first mounting part and the second mounting part are provided with a female head assembly 28, which can facilitate the installation and electrical connection of the female head assembly 28. The outer wall of the conductive sleeve of the female head assembly 28 can be provided with external threads, and it is fixed in the bolt holes provided on the first connecting plate 26 and the second connecting plate 27 by double nut locking.

[0062] Reference Figures 3 to 5 The busbar trunking 2 includes a housing 22 covering the conductive busbar 21. The housing 22 can be made of plastic or metal. A sealing plate 23 is fixed to one end of the housing 22 near the box body 1. The sealing plate 23 is detachably connected to the box body 1 for easy installation and maintenance. A sealing block 24 is provided at the end of the housing 22 away from the box body 1. The sealing block 24 is provided on the upper and lower sides of this end of the housing 22, and a ground wire connection plate 25 is installed on the sealing block 24. The upper and lower sealing blocks 24 and the ground wire connection plate 25 connected in the middle together surround the outer periphery of the end of the conductive busbar. An insulating seal 244 is provided between the ground wire connection plate 25 and the conductive busbar 21. This can ensure the insulation and sealing of the end of the conductive busbar 21 and prevent leakage and short circuit. The housing 22 is composed of two symmetrically arranged ribs 221 and a flange plate 222 connected between the two ribs 221. This structure can improve the strength and stability of the housing 22.

[0063] Reference Figures 3 to 5The flange plate 222 has fixing grooves 223 arranged along its length on both sides. The edge sealing block 24 is fixed in the fixing groove 223, and a water-stop sealing strip 243 is sandwiched between the edge sealing block 24 and the groove wall of the fixing groove 223. The water-stop sealing strip 243 can prevent water vapor from entering the interior of the housing 22. The edge sealing block 24 has positioning flanges on both sides, which are adapted to abut against the end of the fixing groove 223 to achieve axial positioning and ensure accurate installation position of the edge sealing block 24. The edge sealing block 24 also has a boss 241 extending along its length, and the ground wire connecting plate 25 is symmetrically fixed on both sides of the boss 241.

[0064] Reference Figures 6 to 7 The sealing block 24 has a snap-fit ​​groove 242, and the ground wire connecting plate 25 has a right-angle snap-fit ​​edge 251 that matches the snap-fit ​​groove 242. The ground wire connecting plate 25 is positioned by the cooperation between the right-angle snap-fit ​​edge 251 and the snap-fit ​​groove 242, which realizes the compaction of the seal and facilitates the bolt fastening to the boss 241 later.

[0065] The implementation principle of this embodiment is as follows: The busbar trunking quick connection power supply equipment of this embodiment achieves rapid connection and stable power supply between busbar trunkings through the reasonable design and coordination of the busbar trunking connection box, conductive busbar 21, female connector assembly 28 and connecting cable 5; the staggered arrangement of conductive busbar 21 and the parallel connection of female connector assembly 28 improve the reliability and safety of power supply; the setting of heat pipe 4 and heat conduction plate 3 effectively reduces the temperature of female connector assembly 28 and extends its service life; compared with the prior art, this equipment is simple to operate, has high connection efficiency, and can meet the requirements of modern power systems for efficient and stable power supply. Example 2

[0066] Reference Figures 8 to 10 The difference between this embodiment and Embodiment 1 is that a heat pipe 4 is embedded in the tail of the conductive sleeve of the female connector assembly 28. The evaporation section of the heat pipe 4 is located at the tail of the conductive sleeve, and the condensation section of the heat pipe 4 extends out of the tail of the conductive sleeve and makes thermal contact with the heat-conducting plate 3 fixed to the inner wall of the housing 1. The heat pipe 4 has good thermal conductivity and can quickly conduct the heat generated at the tail of the conductive sleeve to the heat-conducting plate 3, thereby reducing the temperature at the tail of the conductive sleeve and improving the stability and service life of the female connector assembly 28. The heat-conducting plate 3 is provided with several insulating heat-conducting seats 31. The insulating heat-conducting seats 31 can be made of boron nitride ceramic material with a thermal conductivity of about 30~100 W / (m·K) and can be machined. The insulating heat-conducting seats 31 are provided with insertion grooves 32 that are adapted to the condensation section of the heat pipe 4, which can ensure good contact between the heat pipe 4 and the heat-conducting plate 3 and improve the thermal conductivity.

[0067] Reference Figures 8 to 10The housing 1 is equipped with several sets of thermometers 6, which can be pressure thermometers 6. The sensing end of each set of thermometers 6 is fixed on an insulating heat-conducting base 31 corresponding to a different female connector assembly 28 connected in parallel with the same conductive busbar 21. The scale area of ​​the thermometer 6 is divided into a cold state indication area, a safe operation area, a warning area, and a danger alarm area along the direction of pointer deflection, from low temperature to high temperature, and is marked with different color bands. The temperature of the female connector assembly 28 can be monitored in real time through the thermometers 6, and abnormalities can be detected in time to ensure the safe operation of the equipment.

[0068] Reference Figures 8 to 10 By comparing the readings of thermometers 6 on the insulating heat-conducting bases 31 corresponding to different female connector assemblies 28 fixed in parallel on the same conductive busbar 21, the faulty connection cable 5 circuit related to the conductive busbar 21 can be located. Specifically, during inspection, the pointer positions and color zones of each thermometer 6 in the same pairing group are manually compared, and the connection status is judged according to the following logic: if both pointers point to the safe operating zone and their positions are basically overlapping, it is determined that each parallel connection path on the conductive busbar 21 is normal; if one pointer points to the cold state indication zone or is significantly lower than the other pointer, while the other pointer points to the warning zone or danger alarm zone, it is determined that the connection cable 5 circuit with the pointer in the cold state indication zone has an open circuit or extremely high contact resistance fault; if both pointers are higher than the safe operating zone, but one continuously and stably points to a color zone higher than the other, it is determined that there is a potential risk of increased contact resistance at the connection point on the higher temperature side of the pointer.

[0069] The implementation principle of this application embodiment is as follows: Several sets of thermometers 6 are set on the housing 1, and the sensing end of each set of thermometers 6 is fixed on the insulating heat-conducting base 31 corresponding to different female connector components 28 connected in parallel with the same conductive busbar 21, which can accurately monitor the temperature of each female connector component 28; since these female connector components 28 are connected in parallel with the same conductive busbar 21, their working status will affect the power supply stability of the entire system. By acquiring their temperature data in real time through the thermometers 6, potential abnormal heating problems can be detected in time. Example 3

[0070] This application also discloses a method for quick connection of busbar trunking power supply, which uses the quick connection power supply equipment for busbar trunking as described in the above embodiments, and specifically includes the following steps:

[0071] S1. At least two female connector assemblies 28 are pre-installed on the corresponding conductive busbars of the first and second busbar trunkings that need to be interconnected. The pre-installation of the female connector assemblies 28 can be completed during the production of the busbar trunking or during on-site installation. The installation method of the female connector assemblies 28 can be selected according to the actual situation, such as welding, bolt connection, etc.

[0072] S2. Provide at least two independent connecting cables 5, each connecting cable 5 having a male connector 51 that matches the female connector 28 at both ends; the connecting cables 5 can be selected in different specifications and lengths according to actual needs, and the mating method between the male connector 51 and the female connector 28 should ensure good electrical and mechanical connection;

[0073] S3. At least two connecting cables 5 are respectively connected to the female connector 28 pre-installed on the same conductive busbar in the first busbar through male connector 51 to form a parallel electrical connection; the parallel electrical connection can improve the reliability of power supply, and when one connecting cable 5 fails, the other connecting cables 5 can still ensure the transmission of power.

[0074] S4. Insert the other end of the connecting cable 5 into the corresponding female connector 28 pre-installed on the conductive busbar of the second busbar through the male connector 51; during the insertion process, pay attention to the alignment and fit of the male connector 51 and the female connector 28 to ensure the stability of the electrical connection.

[0075] S5. When a fault is detected in the current power supply circuit between the first busbar and the second busbar by monitoring the temperature difference between different female connector assemblies connected in parallel with the same conductive busbar, the male connector assemblies at both ends of the connecting cable corresponding to the faulty circuit are removed from the female connector assemblies and replaced. Fault monitoring can be performed using devices such as temperature sensors and current sensors. Timely detection of faults and replacement of connecting cables 5 can ensure the continuity of power supply.

[0076] S6. Maintain at least one working connection cable 5 in a plugged-in state to continue transmitting power between the first busbar and the second busbar through the working connection cable 5; this ensures that basic power supply requirements can still be maintained during the replacement of the faulty connection cable 5.

[0077] The implementation principle of this application embodiment is as follows: the pre-installed female connector assembly 28 and the use of connecting cable 5 realize the rapid connection and power supply between busbars; the parallel electrical connection improves the reliability of power supply, and the connecting cable 5 can be replaced in time when a fault occurs to ensure the continuity of power supply; compared with the prior art, this method is simple to operate, can quickly build and adjust the power system, and meet the requirements of modern power systems for efficient and stable power supply.
