[0033] Determine the unit weight of the primary lead wire, and determine the weight and value based on the unit weight and the height of the terminal block to be installed;

[0034] The weight and value are determined according to the following formula:

[0035] Wz = W0 + d × h;

[0036] Where Wz represents the combined weight of the terminal block to be installed and the primary lead wire, in kg; W0 represents the initial weight of the terminal block to be installed, in kg; d represents the unit weight of the primary lead wire, in kg / m; and h represents the height of the terminal block to be installed, in m.

[0043] Furthermore, the variable speed motor is a brushless copper core motor.

[0044] Furthermore, it also includes a power supply module for supplying power to the variable speed motor.

This method enables automated control of the reinstallation process for primary lead terminal blocks in substations, facilitating equipment maintenance and management. Attached Figure Description

[0054] Figure 2 This is a functional block diagram of the present invention. Detailed Implementation

[0055] The present invention will now be described in more detail with reference to the embodiments.

[0056] Example 1

[0057] like Figure 1 As shown, the present invention provides a method for reassembling and controlling the primary lead terminal block of a substation, comprising:

[0058] Connect the reassembly auxiliary device to the terminal block to be installed and obtain the initial weight of the terminal block to be installed.

[0059] The initial rotation parameters of the variable speed motor are set according to the initial weight, and the initial rotation parameters include the initial speed and the initial direction.

[0060] The real-time speed of the terminal block to be installed is obtained, and the motion state of the terminal block to be installed is determined based on the real-time speed. The motion state includes uniform motion state and variable speed motion state.

[0061] If the terminal block to be installed is in a constant speed motion state, the real-time speed is compared with the preset speed, and the initial speed of the variable speed motor is adjusted according to the comparison result.

[0062] If the terminal block to be installed is in a variable speed motion state, then obtain the traction force of the wire rope in the reassembly auxiliary device and the height of the terminal block to be installed.

[0063] The load-bearing weight of the reassembly auxiliary device is determined based on the height of the terminal block to be installed.

[0064] The initial speed of the variable speed motor is adjusted according to the load-bearing weight and traction force so that the terminal block to be installed reaches the predetermined position for reinstallation.

[0065] In some embodiments of this application, the reassembly auxiliary device includes a variable speed motor, a wire reel, and a wire rope. The output shaft of the variable speed motor is connected to the wire reel, one end of the wire rope is connected to the wire reel, and the other end of the wire rope is connected to the terminal block to be installed.

[0066] The reassembly auxiliary device includes a variable-speed motor, a wire reel, and a wire rope. The output shaft of the variable-speed motor is tightly connected to the wire reel, ensuring that the motor's power is effectively transmitted to the wire reel. The wire reel is a device designed to wind the wire rope; it can withstand the tension of the wire rope and evenly release or wind it up. One end of the wire rope is securely connected to the wire reel, so that the wire rope can be wound up or unwound as the reel rotates. The other end of the wire rope is connected to the terminal block to be installed. By winding and unwinding the wire rope, the raising and lowering of the terminal block can be controlled, thereby achieving precise installation of the terminal block. The entire reassembly auxiliary device is designed to simplify the terminal block installation process, improve work efficiency, and ensure the safety of the installation process.

[0067] In some embodiments of this application, a speed sensor is provided on the terminal block to be installed, which is used to detect the real-time speed of the terminal block to be installed; a position sensor is provided on the terminal block to be installed, which is used to detect the height of the terminal block to be installed; and a force sensor is provided on the wire rope, which is used to detect the traction force of the wire rope.

[0068] In this invention, multiple sensors are designed into the terminal block to be installed to ensure the accuracy and safety of the installation process. First, a speed sensor is cleverly integrated into the terminal block, and its main function is to monitor the moving speed of the terminal block in real time during installation. By accurately measuring the speed, the system can ensure that the terminal block moves at the appropriate speed, avoiding installation errors or damage caused by excessive or insufficient speed.

[0069] In addition, to further improve installation accuracy, a position sensor is also equipped on the terminal block to be installed. This sensor focuses on detecting the height position of the terminal block, thereby improving overall installation efficiency and accuracy by monitoring height information in real time.

[0070] To monitor the mechanical state throughout the installation process, a force sensor is installed on the wire rope. This sensor measures the force exerted on the wire rope when it is pulled by the terminal block. By monitoring the traction force in real time, the system can promptly detect any abnormal force changes, such as overload or sudden changes in force, and take appropriate measures.

[0071] In some embodiments of this application, setting the initial rotation parameters of the variable speed motor based on the initial weight includes: presetting a first weight and a second weight, wherein the first weight is less than the second weight; setting the initial speed of the variable speed motor based on the relationship between the initial weight and the first weight and the second weight; if the initial weight is less than the first weight, then the initial speed of the variable speed motor is determined to be a first speed N1; if the initial weight is greater than or equal to the first weight and the initial weight is less than the second weight, then the initial speed of the variable speed motor is determined to be a second speed N2; if the initial weight is greater than or equal to the second weight, then the initial speed of the variable speed motor is determined to be a third speed N3; and N1 > N2 > N3.

[0072] In some embodiments of this application, the real-time speed is compared with a preset speed, and the initial speed of the variable speed motor is adjusted according to the comparison result. This includes: if the real-time speed is less than or equal to the preset speed, the initial speed of the variable speed motor is not adjusted; if the real-time speed is greater than the preset speed, the speed difference between the real-time speed and the preset speed is determined, and the initial speed of the variable speed motor is adjusted according to the speed difference.

[0073] In a real-time monitoring system, the real-time speed changes dynamically, reflecting the current operating status of the equipment. Simultaneously, a preset speed is set; this speed is the target speed the equipment is expected to achieve, which may be based on optimal work efficiency, safety standards, or specific task requirements.

[0074] The system continuously compares and analyzes the real-time speed with the preset speed. This comparison process is performed in real time, ensuring timely response to changes in equipment speed. The results of the comparison analysis will determine whether the initial speed of the variable speed motor needs to be adjusted.

[0075] Specifically, if the real-time speed is less than or equal to the preset speed, it indicates that the equipment's operating speed is as expected or has reached its upper limit. Therefore, in this case, no adjustment to the initial speed of the variable-speed motor is needed. This avoids unnecessary operation, reduces energy consumption, and prevents potential damage to the equipment. However, if the real-time speed is greater than the preset speed, it means that the equipment's operating speed exceeds the set range. In this case, measures need to be taken to reduce the speed to ensure that the equipment operates within a safe and efficient range. To do this, first determine the speed difference between the real-time speed and the preset speed. This difference reflects the degree to which the current speed exceeds the preset speed. Based on this speed difference, the required adjustment to the initial speed of the variable-speed motor can be calculated. The purpose of the adjustment is to bring the equipment's operating speed back to the preset speed range. The magnitude and method of the adjustment will be determined based on the specific application scenario and equipment characteristics, and may include gradual deceleration, rapid deceleration, or other control strategies to ensure a smooth adjustment process without impacting the equipment.

[0076] This real-time monitoring and dynamic adjustment mechanism ensures that the equipment always operates in optimal condition, which improves production efficiency and guarantees the long-term stability and safety of the equipment.

[0077] In some embodiments of this application, adjusting the initial speed of the variable speed motor according to the speed difference includes: presetting a first speed difference and a second speed difference, wherein the first speed difference is less than the second speed difference; setting a speed adjustment coefficient according to the relationship between the speed difference and the first speed difference and the second speed difference; adjusting the initial speed Ni based on the set speed adjustment coefficient, i = 1, 2, 3; if the speed difference is less than the first speed difference, then setting the speed adjustment coefficient to a first preset adjustment coefficient a1, and adjusting the initial speed to a1*Ni; if the speed difference is greater than or equal to the first speed difference and the speed difference is less than the second speed difference, then setting the speed adjustment coefficient to a second preset adjustment coefficient a2, and adjusting the initial speed to a2*Ni; if the speed difference is greater than or equal to the second speed difference, then setting the speed adjustment coefficient to a third preset adjustment coefficient a3, and adjusting the initial speed to a3*Ni; wherein, 1 > a1 > a2 > a3 > 0.

[0078] In this embodiment, in order to make the real-time speed close to the preset speed, it is necessary to adjust the rotational speed of the variable speed motor. By adjusting the initial rotational speed, the real-time speed can reach the preset speed.

[0079] In some embodiments of this application, determining the load-bearing weight of the reassembly auxiliary device based on the height of the terminal block to be installed includes: the terminal block to be installed is fixedly connected to the primary lead wire, and the load-bearing weight is the sum of the weights of the terminal block to be installed and the primary lead wire; determining the unit weight of the primary lead wire, and determining the weight and value based on the unit weight and the height of the terminal block to be installed;

[0080] The weight and value are determined according to the following formula:

[0081] Wz = W0 + d × h;

[0082] Where Wz represents the combined weight of the terminal block to be installed and the primary lead wire, in kg; W0 represents the initial weight of the terminal block to be installed, in kg; d represents the unit weight of the primary lead wire, in kg / m; and h represents the height of the terminal block to be installed, in m.

[0083] During the installation of the junction box, the first step is to determine the load-bearing capacity of the reassembly auxiliary device based on the height of the junction box to be installed. The junction box to be installed is fixedly connected to the primary lead. The primary lead typically refers to the main cable or conductor from the power source to the junction box. Therefore, the load-bearing capacity should include the weight of the junction box itself and the weight of the primary lead. The sum of these two weights is the total weight that the reassembly auxiliary device must be able to safely bear.

[0084] To accurately calculate this weight and value, the unit weight of the primary lead needs to be determined first. Unit weight refers to the weight of a unit length of primary lead. Once the unit weight is known, the total weight of the primary lead can be calculated by measuring the height of the terminal block to be installed. Adding the total weight of the primary lead to the weight of the terminal block to be installed yields the weight and value that the reassembly auxiliary device needs to bear.

[0085] In some embodiments of this application, adjusting the initial speed of the variable speed motor based on the load weight and traction force includes: determining the load-bearing weight of the reassembly auxiliary device based on the load weight; determining the force difference between the load weight and the traction force; and adjusting the initial speed of the variable speed motor based on the force difference.

[0086] In some embodiments of this application, adjusting the initial speed of the variable speed motor according to the force difference includes: comparing the load-bearing gravity with the traction force; if the load-bearing gravity is less than the traction force, adjusting the initial speed of the variable speed motor to increase the speed according to the force difference; if the load-bearing gravity is greater than the traction force, adjusting the initial speed of the variable speed motor to decrease the speed according to the force difference.

[0087] To ensure the efficient and safe operation of the assembly auxiliary device under different load conditions, the initial speed of the variable-speed motor needs to be precisely adjusted. The system determines the load-bearing capacity of the assembly auxiliary device based on the current load weight. Once the load-bearing capacity is determined, the next step is to calculate the force difference between the load-bearing capacity and the traction force. Traction force refers to the force that the assembly auxiliary device needs to overcome when performing a task, such as lifting an object. This force difference is a key parameter under actual working conditions, reflecting the additional resistance that the assembly auxiliary device needs to overcome under the current load. Finally, based on the calculated force difference, the system adjusts the initial speed of the variable-speed motor.

[0088] The initial speed of the variable-speed motor is adjusted based on the force difference value. The specific steps are as follows: First, compare and analyze the load-bearing gravity and the traction force. If the load-bearing gravity is less than the traction force, it means that the current traction force is sufficient to overcome gravity. To improve efficiency and response speed, the initial speed of the variable-speed motor needs to be increased. After the speed-increasing adjustment, the motor torque decreases, and the traction force decreases. Conversely, if the load-bearing gravity is greater than the traction force, it indicates that the current traction force is insufficient to overcome gravity, which may lead to slow or stalled equipment operation. In this case, the initial speed of the variable-speed motor needs to be decreased to reduce energy consumption and avoid motor overload. The magnitude of the deceleration adjustment can also be determined based on the force difference value; the larger the force difference value, the larger the deceleration adjustment should be. In this way, it can be ensured that the initial speed of the variable-speed motor always matches the actual traction force and load-bearing gravity, thereby optimizing the operating efficiency and performance of the equipment.

[0094] The parameter adjustment module is used to compare the real-time speed with the preset speed when the terminal block to be installed is in a uniform motion state, and adjust the initial speed of the variable speed motor according to the comparison result; it is also used to determine the load-bearing weight of the reassembly auxiliary device according to the height of the terminal block to be installed when the terminal block to be installed is in a variable speed motion state; and adjust the initial speed of the variable speed motor according to the load-bearing weight and traction force so that the terminal block to be installed reaches the predetermined position to achieve reassembly.
