Description

Technical Field

[0001] This invention belongs to the field of cooling technology, and in particular relates to a temperature measurement and automatic cooling system for power distribution rooms. Background Technology

[0002] A power distribution room, also known as a distribution substation, is an indoor electrical distribution facility with low-voltage loads. It primarily distributes power to low-voltage users and includes medium-voltage incoming lines (with a few outgoing lines), distribution transformers, and low-voltage distribution equipment. Facilities for equipment with voltage levels of 10kV and below are divided into high-voltage distribution rooms and low-voltage distribution rooms. High-voltage distribution rooms generally refer to 6kV-10kV high-voltage switch rooms; low-voltage distribution rooms generally refer to 400V distribution rooms with 20kV or 35kV station service transformer outgoing lines.

[0003] During normal operation, the power distribution room needs to be sealed according to the prescribed protection requirements, with only one exhaust fan for ventilation and heat dissipation. In summer, the hot weather, coupled with the heat generated by the power distribution equipment itself, makes the temperature inside the power distribution room extremely high. The equipment in the power distribution room may malfunction due to excessive temperature, which will greatly affect work and life, increase the workload of on-duty personnel, and even easily lead to accidents, posing a great safety hazard. Moreover, during the use of the existing exhaust fans, the vibration excitation generated by the axial flow fan due to the decrease in its rotation speed coupled with the structural mode, will cause resonance after a period of operation, resulting in a number of failures.

[0004] In existing technologies, the cooling effect of power distribution rooms is poor, the degree of automation of power distribution room cooling is low, and the exhaust fans used have a high failure rate and short service life. Therefore, a power distribution room measurement and automatic cooling device is proposed. Summary of the Invention

[0026] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0027] To resolve or improve the issues raised in the background, please refer to Figure 1-5 As shown, the present invention is a power distribution room measurement and automatic cooling equipment / system, including a cooling device and a control system / device. The cooling device includes a housing 1, a connecting component on the housing 1, and an exhaust fan 2 on the connecting component. The exhaust fan 2 is mainly used to continuously ventilate the power distribution room to complete the cooling.

[0028] The housing 1 has an opening on one side and a circular through hole on the other side. A temperature sensor 3 is installed on the inner side wall of the housing 1. The connecting assembly includes a mounting platform 4 and a spiral ring 5. The mounting platform 4 is located at the center of the circular through hole. The inner end of the spiral ring 5 is fixedly connected to the side wall of the mounting platform 4. Several fixing rings 6 are provided on the upper part of the spiral ring 5. The fixing rings 6 are evenly spaced and arrayed. A first groove is formed on the lower surface of the fixing ring 6. The inner surface of the first groove fits against the spiral ring 5. One end of the fixing ring 6 is located inside the circular through hole, and the other end of the fixing ring 6 is located outside the circular through hole. The other end of the fixing ring 6 is located inside the corner of the box body 1. The upper end of the fixing ring 6 is provided with a first reinforcing plate 7, and the lower end of the spiral ring 5 is provided with a second reinforcing plate 8. The second reinforcing plate 8 is located directly below the first reinforcing plate 7. The upper surface of the second reinforcing plate 8 is provided with a second groove, which fits into the spiral ring 5. Both ends of the first reinforcing plate 7 are located inside the circular through hole, and the second reinforcing plate 8 is the same size as the first reinforcing plate 7.

[0029] The temperature sensor 3 is mainly used to collect the indoor temperature of the power distribution room. Before actual production, a surrogate model is constructed using the Kriging method. Its inputs are four characteristic parameters of the vortex coil 5 reinforcement structure: the length, width, and thickness of the first reinforcing plate 7 and the number of the first bolts 12. The outputs are five vibration performance parameters: the vibration acceleration and velocity of the motor 21, the maximum deformation of the fan blades, and the natural frequencies of the first two modes. First, a Latin hypercube design is used to obtain a training sample set of 60 data sets. This is a sampling method specifically used for computer simulation experiments, which ensures the uniformity of the projection of each parameter. Then, the mapping relationship between the input and output is fitted using a Kriging model to obtain... The correlation coefficients R² between the five outputs and each input were calculated. R² represents the global accuracy of the model; the closer R² is to 1, the higher the accuracy. The experimental measurement results are as follows: vibration acceleration correlation coefficient is 0.90; vibration velocity correlation coefficient is 0.89; maximum blade deformation correlation coefficient is 0.84; first-order natural frequency correlation coefficient is 0.96; second-order natural frequency correlation coefficient is 0.91. Through vibration performance evaluation tests and long-life vibration tests of axial flow fan 2 in the laboratory, the vibration reduction effect of the optimal modification scheme was verified, resonance phenomenon was reduced, the failure rate of exhaust fan 2 after long-term use was reduced, the service life of exhaust fan 2 was improved, and the cooling effect of the power distribution room was improved.

[0030] The housing 1 is provided with a plurality of first connecting rings 9, which are arranged in an array at equal intervals. The first connecting rings 9 are located at the other end and directly below the fixing ring 6. The other end of the fixing ring 6 is provided with a second connecting ring 10. The first connecting rings 9 and the second connecting ring 10 are provided with a first through hole. The housing 1 is provided with a second through hole. The position of the second through hole is adapted to the position of the first through hole. A first bolt 12 is provided in the first through hole. One end of the first bolt 12 passes through the second through hole and is threaded to a nut. The other end of the fixing ring 6 is used with the first connecting rings 9 and the second connecting ring 10 to fix the fixing ring 6 to the housing 1, thereby improving the stability of the connection.

[0031] The fixing ring 6 and the vortex ring 5 are located between the first reinforcing plate 7 and the second reinforcing plate 8. The first reinforcing plate 7 and the second reinforcing plate 8 have third through holes at their two ends. The third through holes are provided with second bolts 13, which pass through the first reinforcing plate 7 and are connected to the nut. By setting the first reinforcing plate 7 and the second reinforcing plate 8 on both sides of the fixing ring 6 and the vortex ring 5, and by having a second groove on the upper surface of the second reinforcing plate 8 that fits into the vortex ring 5, and a first groove on the lower surface of the fixing ring 6 that fits into the vortex ring 5, the vortex ring 5 is completely clamped. At the same time, the first reinforcing plate 7 and the second reinforcing plate 8 make the installation of the exhaust fan 2 more compact, reduce the resonance phenomenon of the exhaust fan 2, and improve the service life of the exhaust fan 2.

[0032] The exhaust fan 2 includes a motor 21 and an output shaft 22. The output shaft 22 is fixedly connected to the mounting platform 4. Several fan blades 23 are connected to the side wall of the motor 21. The fan blades 23 are distributed in a row at equal intervals. The central axis of the output shaft 22 is aligned with the central axis of the mounting platform 4. The motor 21 is mainly used to rotate when the output shaft 22 is fixed. The motor 21 drives the fan blades 23 to rotate, thus completing the operation of the exhaust fan 2.

[0033] The outer side wall of the enclosure 1 is provided with a rectangular block 11, and the rectangular block 11 is provided with an installation through hole. The equipment is installed in the ventilation box opened in the wall of the power distribution room through the rectangular block 11.

[0034] The system includes two automatic cooling devices installed inside the power distribution room. The control system comprises a temperature acquisition module, a temperature setting module, a temperature control module, and a drive module. The temperature acquisition module obtains temperature data from the power distribution room via temperature sensor 3 and uploads this data to the control computer. The temperature setting module first sets three operating conditions: normal temperature, high temperature, and ultra-high temperature, generating set data. The temperature control module obtains both the temperature data and the set data through software running within the control computer, compares the temperature data with the set data, and outputs the control result. The two automatic cooling devices are electrically connected to the control computer. The drive module includes an automatic drive unit and a manual drive unit. The automatic drive unit automatically controls the operation of the two automatic cooling devices via a PLC based on the control result. The manual drive unit controls the operation of the two automatic cooling devices via a mechanical switch. By setting up the control system, automatic control can be achieved, improving the cooling effect of the power distribution room.

[0035] The software system defines a normal temperature as below 35℃, a high temperature as 35℃-45℃, and an ultra-high temperature as above 45℃. When the temperature inside the power distribution room is less than 35℃, the software system generates a first control signal. When the temperature inside the power distribution room is between 35℃ and 45℃, the software system generates a second control signal. When the temperature inside the power distribution room is greater than 45℃, the software system generates a third control signal. The first, second, and third control signals serve as the control results. By setting the normal temperature, high temperature, and ultra-high temperature, automatic control is achieved to complete different corresponding operations, avoiding resource waste caused by the continuous operation of all exhaust fans 2, thus saving resources.

[0036] Specifically, after acquiring the first control signal, the drive module controls an automatic cooling device to work for two minutes every thirty minutes to achieve air exchange; after acquiring the second control signal, the drive module controls an automatic cooling device to work to cool down; and after acquiring the third control signal, the drive module controls two automatic cooling devices to work to cool down. The temperature sensor 3 detects once every two minutes.

[0037] The working principle of this invention is as follows: First, the automatic cooling device is installed in the wall of the power distribution room. Then, the temperature acquisition module obtains the temperature data inside the power distribution room through the temperature sensor 3. For example, if the temperature data is 25 degrees Celsius, the software system generates a first control signal. After obtaining the first control signal, the drive module controls one automatic cooling device to work for two minutes every thirty minutes to achieve ventilation. For example, if the temperature data is 40 degrees Celsius, the software system generates a second control signal. After obtaining the second control signal, the drive module controls one automatic cooling device to work for cooling. For example, if the temperature data is 50 degrees Celsius, the software system generates a third control signal. After obtaining the third control signal, the drive module controls two automatic cooling devices to work for cooling. During the operation, the motor 21 is mainly used to rotate under the premise that the output shaft 22 is fixed. The motor 21 drives the fan blade 23 to rotate, completing the operation of the exhaust fan 2, which is used to continuously ventilate the power distribution room to achieve cooling.
