Description
Technical Field
[0001] This application relates to the field of power supply for chicken farms, and in particular to a high and low voltage power distribution system suitable for ultra-large chicken farms. Background Technology
[0002] In modern aquaculture, the electricity consumption of super-large farms is enormous. Once a power failure occurs, it may cause huge losses. Ensuring the normal operation of the farm is of paramount importance.
[0003] In related technologies, high-voltage, low-voltage, and transformers in ultra-large chicken farms are centrally located in a room or area for centralized management. However, centralized management results in higher costs for laying low-voltage lines and relatively higher low-voltage drop. Furthermore, a power outage in the centralized management area can cause widespread equipment shutdowns and significant losses, thus requiring further improvements. Utility Model Content
[0004] To reduce the electricity risks and losses of ultra-large chicken farms, this application provides a high and low voltage power distribution system suitable for ultra-large chicken farms.
[0005] This application provides a high- and low-voltage power distribution system suitable for ultra-large chicken farms, which adopts the following technical solution:
[0006] A high- and low-voltage power distribution system suitable for ultra-large chicken farms includes a high-voltage power distribution room, multiple low-voltage power distribution rooms, multiple box-type transformers, and multiple diesel generator sets. The high-voltage power distribution room is electrically connected to the municipal high-voltage circuit and the multiple box-type transformers. The low-voltage power distribution rooms are electrically connected to the diesel generator sets and the box-type transformers respectively. Each low-voltage power distribution room is connected to the electrical equipment of a power consumption area. The power consumption area includes a predetermined number of chicken houses. There are multiple power consumption areas, and each power consumption area is equipped with one low-voltage power distribution room.
[0007] By adopting the above technical solution, the high-voltage distribution room, connected to the municipal high-voltage circuit and a box-type transformer, can provide a stable high-voltage power input to the entire system. Simultaneously, the box-type transformer supplies power to the low-voltage distribution room. This divides the electrical equipment within the chicken farm into power consumption zones, with each zone having its own low-voltage distribution room for decentralized management. This reduces the cost of laying low-voltage lines, saving investment and facilitating management, thus mitigating electrical risks. In the event of a fault in a power consumption zone, troubleshooting and repair are easier, reducing losses and electrical risks associated with power outages affecting the entire chicken farm due to centralized management. This decentralized management provides a primary level of protection for very large-scale chicken farms. When the mains power supply is abnormal, the low-voltage distribution room is connected to the diesel generator set, which can provide power through the diesel generator to ensure continuous power supply. When a circuit failure occurs in a low-voltage distribution room, the diesel generator can also be used to provide power without affecting other power consumption areas. The diesel generator set installed has played a secondary protection role for this super-large chicken farm, thereby reducing the power supply risk of the large chicken farm and reducing the losses caused by power outages.
[0008] Optionally, each of the chicken houses has two access boxes in the rear control room, and each access box is electrically connected to the low-voltage power distribution room using an independent circuit. Each of the two access boxes in the rear control room is connected to half of the fans in the chicken house.
[0009] By adopting the above technical solution, when one inlet box circuit fails, the other inlet box can supply power to the chicken house, allowing the fan to continue operating. This design makes the power supply to the fan more balanced, avoids the problem of overload that may be caused by a single power supply line, improves the reliability of power supply, and enables the chicken house to maintain a certain temperature, reducing damage and losses.
[0010] Optionally, the low-voltage distribution room is equipped with two low-voltage cabinets, and one diesel generator set includes two diesel generators. Each diesel generator is electrically connected to a low-voltage cabinet, and each low-voltage cabinet is electrically connected to an inlet box in the rear control room of the same chicken house. The two diesel generators are not connected to a parallel cabinet or a switching cabinet.
[0011] By adopting the above technical solution, two low-voltage switchgear are set up to be connected to two inlet boxes respectively, and each diesel generator is electrically connected to one low-voltage switchgear. This allows one diesel generator to control a general fan. When one diesel generator fails, the other diesel generator can supply power to the chicken house, enabling half of the fans to operate. This allows the chicken house to maintain a certain temperature, reducing damage and losses. It also reduces the losses and power risks associated with having only one diesel generator. The diesel generators provide secondary protection for this large-scale chicken farm.
[0012] Optionally, the high-voltage distribution room is electrically connected to two municipal high-voltage circuits, with the two municipal high-voltage circuits serving as backup circuits for each other.
[0013] By adopting the above technical solution, the two municipal high-voltage circuits serve as backup circuits for each other. When one of the municipal high-voltage circuits fails or needs maintenance, the other municipal high-voltage circuit can continue to provide power to the high and low voltage power distribution system of the chicken farm, playing a dual protection role, ensuring the normal operation of various electrical equipment in the chicken farm, and avoiding production losses caused by power outages.
[0014] Optionally, the chicken coops are arranged side by side, and a predetermined number of adjacent chicken coops are designated as the same power consumption area.
[0015] By adopting the above technical solution, a low-voltage power distribution room is used to supply power to adjacent chicken houses, dividing the adjacent chicken houses into the same power consumption area. This allows for centralized management of power distribution, reduces the complexity of the power distribution system, reduces line losses, and facilitates maintenance and troubleshooting.
[0016] Optionally, a mobile generator is installed in the power consumption area, and the power of the mobile generator is the same as that of the diesel generator.
[0017] By adopting the above technical solution, when both diesel generators connected in a power consumption area are completely damaged, a mobile generator can be used to make up for the damage and provide power to the power consumption area. This provides a three-level protection effect for the super-large chicken farm, thereby reducing the power consumption risk of the large chicken farm and reducing the losses caused by power outages.
[0018] Optionally, a protective cover is provided outside the diesel generator or the mobile generator. A sound insulation layer is provided inside the protective cover. A first heat dissipation hole is provided through the sound insulation layer. A second heat dissipation hole communicating with the first heat dissipation hole is provided outside the protective cover. The second heat dissipation hole is partially offset from the first heat dissipation hole. Sound-absorbing cotton is provided inside both the first and second heat dissipation holes.
[0019] By adopting the above technical solutions, a protective cover is installed outside the diesel generator or mobile generator, effectively isolating the equipment from the influence of the external environment and protecting the safety of operators. The sound insulation layer inside the protective cover significantly reduces the noise generated during generator operation, minimizing disturbance to chickens in the chicken farm and improving the comfort of the farming environment. The placement of the first and second heat dissipation holes ensures air circulation inside and outside the protective cover, preventing overheating of the equipment due to a sealed environment. The partial misalignment of the first and second heat dissipation holes further enhances the sound insulation effect, preventing noise from being directly transmitted to the outside and increasing the difficulty for rainwater to enter the protective cover through the first and second heat dissipation holes.
[0020] Optionally, sound-absorbing cotton is provided inside both the first and second heat dissipation holes.
[0021] By adopting the above technical solution, sound-absorbing cotton is installed in the first and second heat dissipation holes, which can absorb the remaining noise and further improve the noise reduction performance.
[0022] Optionally, a vibration isolation component is provided between the diesel generator or the mobile generator and the protective cover.
[0023] By adopting the above technical solution and installing vibration isolation components, the noise generated by the generator during operation through the rigid connection between it and the protective cover can be effectively reduced, thus reducing interference with the chickens in the chicken farm.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] By dividing the electrical equipment within the chicken farm into power zones, with each zone equipped with its own low-voltage distribution room for decentralized management, the cost of laying low-voltage lines is reduced, saving investment. This also minimizes losses and electrical risks associated with power outages affecting the entire chicken farm, a first-level protection measure for large-scale chicken farms. Connecting the low-voltage distribution rooms to diesel generator sets allows for backup power in case of mains power failures or circuit faults in one low-voltage distribution room, without affecting other power zones, providing a second-level protection measure. Furthermore, if both diesel generators in a power zone fail, a mobile generator can be used as a backup, providing a third-level protection measure, thus reducing electrical risks and losses associated with power outages for large-scale chicken farms. The high-voltage power distribution room is connected to two municipal high-voltage circuits, which serve as backup circuits for each other. When one of the municipal high-voltage circuits fails or needs maintenance, the other municipal high-voltage circuit can continue to provide power to the high and low voltage power distribution system of the chicken farm, playing a dual protection role and ensuring the normal operation of all electrical equipment in the chicken farm.

[0032] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.
[0033] Example 1:
[0034] This application discloses a high- and low-voltage power distribution system suitable for ultra-large-scale chicken farms. (Refer to...) Figure 1 and Figure 2 A high- and low-voltage power distribution system suitable for ultra-large chicken farms includes: a high-voltage distribution room 1, a low-voltage distribution room 2, a box-type transformer 3, and a diesel generator set 4. The high-voltage distribution room 1 is electrically connected to the municipal high-voltage circuit 11 and the box-type transformer 3. The low-voltage distribution room 2 is electrically connected to the diesel generator set 4 and the box-type transformer 3. Each low-voltage distribution room 2 connects to the electrical equipment of one power consumption area 5 for decentralized management, reducing losses and electrical risks caused by power outages in the entire chicken farm due to centralized management. This decentralized management provides a primary protection effect for ultra-large chicken farms. Each power consumption area 5 includes a predetermined number of chicken houses, feed stations, processing stations, staff canteens, etc. There are multiple power consumption areas 5, and each power consumption area 5 is equipped with one low-voltage distribution room 2.
[0035] The high-voltage distribution room 1 is connected to two municipal high-voltage circuits 11, which serve as backup circuits for each other, ensuring power supply even if one of the municipal high-voltage circuits 11 fails. The high-voltage current is first distributed from the high-voltage distribution room 1 to each box-type transformer 3, and then from the box-type transformer 3 to each low-voltage distribution room 2. The box-type transformers 3 and low-voltage distribution rooms 2 are located close to each other. The high-voltage circuit is connected from the high-voltage distribution room 1 to the box-type transformer 3, and the high-voltage circuit is suspended above the ground by overhead poles 6 to reduce the safety hazards caused by excessively low voltage levels.
[0036] When dividing the chicken house into power consumption zones 5, since the chicken houses are usually arranged side by side, several adjacent chicken houses are divided into one power consumption zone 5 starting from one side.
[0037] In this embodiment, a set of diesel generators 4 includes two or more diesel generators. A corresponding number of low-voltage switchgear are installed in the low-voltage distribution room 2 to correspond to the diesel generators. The fans 7 inside the chicken house are divided into several equal parts, with each low-voltage distribution room 2 controlling each part of the fans 7. The diesel generator sets 4 provide secondary protection for this large-scale chicken farm, thereby reducing the power supply risks and minimizing losses caused by power outages.
[0038] Specifically, in one implementation scenario, four adjacent chicken houses are designated as a single power consumption area 5. A low-voltage distribution room 2, a box-type transformer 3, and a set of diesel generator sets 4 are installed near these four chicken houses. The low-voltage distribution room 2 contains two low-voltage switchgear. The diesel generator set 4 includes two diesel generators, each electrically connected to one of the low-voltage switchgears. The two diesel generators are not connected to a parallel cabinet or switching cabinet. Each of the two diesel generators generates power for one half of the fans 7 in the chicken houses. This ensures that if one diesel generator fails, the other can still operate, maintaining a certain temperature within the chicken houses and minimizing losses.
[0039] The specific implementation method in the above scenario is as follows: One power supply box is placed in the front-end control room of each chicken house, and it is electrically connected to the low-voltage distribution room 2. Two power supply boxes are placed in the rear-end control room of each chicken house, and each is electrically connected to a low-voltage cabinet in the low-voltage distribution room 2 using an independent circuit. Each of the two power supply boxes in the rear-end control room is connected to half of the fans 7 in the chicken house. When the circuit of one power supply box fails, the other power supply box can provide power to the chicken house, enabling the operation of half of the fans 7, thus maintaining a certain temperature in the chicken house and reducing damage.
[0040] It should be noted that the mains box includes an air switch and a residual current device (RCD). The air switch has the function of quickly cutting off the current, while the RCD is an electronic design that can sensitively detect leakage and cut off the power supply in a timely manner.
[0041] To provide remedial measures in case all diesel generators in a power consumption area 5 fail and are difficult to repair for an extended period, a mobile generator 8 will be installed in a predetermined number of power consumption areas 5. The power of the mobile generator 8 will be the same as that of the diesel generators. When all diesel generators in a power consumption area 5 fail, the mobile generator 8 can be transported to the opposite power consumption area 5 to provide half the power for the fans 7 in the chicken house. This provides a three-level protection effect for the ultra-large chicken farm, thereby improving the safety of electricity use in the ultra-large chicken farm.
[0042] The implementation principle of a high- and low-voltage power distribution system suitable for ultra-large chicken farms in this application embodiment is as follows: the power consumption equipment in the chicken farm is divided into power consumption zones 5, and each power consumption zone 5 is equipped with a low-voltage distribution room 2. This decentralized management provides a first-level protection effect for ultra-large chicken farms. When the mains power supply is abnormal or a circuit failure occurs in one of the low-voltage distribution rooms 2, a diesel generator can be used to supply power without affecting other power consumption zones, thus providing a second-level protection effect for the ultra-large chicken farm. Furthermore, when both diesel generators connected in a power consumption zone fail, a mobile generator 8 can be used as a backup, providing a third-level protection effect for the ultra-large chicken farm, thereby reducing the power consumption risks of large chicken farms and minimizing losses caused by power outages.
[0043] Example 2:
[0044] Reference Figure 3 The difference from Embodiment 1 is that the diesel generator or the mobile generator 8 is covered with a protective cover 9. The protective cover 9 has a sound-absorbing layer 91 inside, and a sound-insulating layer 92 is provided on the surface of the sound-absorbing layer 91 away from the protective layer. A first heat dissipation hole 93 is provided through the sound-insulating layer 92, and the first heat dissipation hole 93 extends to the surface of the sound-absorbing layer 91 near the protective cover 9. A second heat dissipation hole 94 is provided on the outside of the protective cover 9, which communicates with the first heat dissipation hole 93. The second heat dissipation hole 94 is partially misaligned with the first heat dissipation hole 93 to form a labyrinthine heat dissipation channel. Sound-absorbing cotton is provided in both the first heat dissipation hole 93 and the second heat dissipation hole 94 to further reduce noise transmission.
[0045] In this embodiment, the protective cover 9 is made of steel plate, which has the characteristics of high strength and corrosion resistance. The sound insulation layer 92 is made of porous material, which has good sound absorption effect.
[0046] Reference Figure 3 , Figure 4 For the installation between the protective cover 9 and the diesel generator or mobile generator 8, it can be directly covered to the ground. However, the ground will also vibrate to a certain extent, which will change the position of the protective cover 9 and affect the noise isolation. Therefore, a vibration isolation component 10 is installed between the generator and the protective cover 9.
[0047] Reference Figure 4 , Figure 5 The vibration isolation component 10 specifically includes a vibration isolation pad 101, a first screw 102, a first nut post 103, a second screw 104, a mounting plate 105, and a second nut post 106. It should be noted that the protective cover 9 needs to have an opening to allow for starting or stopping the generator.
[0048] The vibration isolation pad 101 is disposed between the protective cover 9 and the generator. The vibration isolation pad 101 has a first through hole 1011 through its own thickness. The end of the first through hole 1011 away from the generator is set as a countersunk hole. The first screw 102 passes through the first through hole 1011 to be threadedly connected with the first nut post 103. The first nut post 103 is disposed on the generator. The first nut post 103 can also be a threaded ring, so as to install the vibration isolation pad 101 on the generator. The vibration damping pad 101 has a second through hole 1012 extending through its own thickness. A mounting groove 1013 for mounting the mounting plate 105 is formed on the surface of the vibration damping pad 101 near the generator. The mounting groove 1013 connects to the second through hole 1012, and its depth is greater than the thickness of the mounting plate 105. Two second nut posts 106 are provided and fixedly connected to the mounting plate 105 respectively. The second nut posts 106 pass through the second through hole 1012. A second screw 104 passes through the protective cover 9 and the second through hole 1012, and is threadedly connected to the second nut posts 106, thereby installing the protective cover 9 onto the vibration damping pad 101, that is, installing the protective cover 9 onto the generator. By providing the vibration damping pad 101, the rigid connection and direct contact between the generator and the protective cover 9 are isolated, and the vibration generated by the generator operation can be absorbed.
[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
