Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings 1 to 10 and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Embodiments of the application are described in further detail below with reference to the drawings.
Referring to fig. 1, an embodiment of the present application provides an online capacity-increasing method for a power transmission line, and a main flow of the online capacity-increasing method for the power transmission line is described as follows:
step 100: and a guide rail is arranged along the transmission direction of the power transmission line, and the measuring instrument moves along the guide rail.
The measuring instrument is an instrument and equipment which can measure the influence factors such as the resistivity of a wire, the ambient temperature, the temperature of the wire, the wind speed, the sunlight intensity and the like which have influence on the current-carrying capacity of the power transmission line, so the measuring instrument is provided with a corresponding sensor. As shown in fig. 2 and 3, a power transmission line is arranged between two elevated frames, the power transmission line sags due to its own weight, a guide rail is installed above the power transmission line, and the guide rail can be in a present straight line shape or any shape, but it should be noted that the guide rail must be above the power transmission line, but the distance between the power transmission line and the guide rail is not infinitely long, i.e. the position corresponding to the straight line guide rail in the figure is within a certain range. The guide rail is provided with a movable trolley, and a measuring instrument is arranged below the trolley. The moving trolley on the guide rail moves according to the specified speed, so that the measuring instrument can detect different data at different positions on the power transmission line.
Step 101: and acquiring horizontal distance information of the measuring instrument along the power transmission line and current sag information of the power transmission line.
The horizontal distance information refers to position information of the measuring instrument in the horizontal direction from the starting point, and includes distance and direction. Sag refers to the vertical distance between the lowest point of a wire and a connecting line between two hanging points when the hanging heights of the wires on two adjacent base poles are the same on a flat ground. Generally, when the transmission distance is long, a slight sag is formed due to the dead weight of the wire, so that the wire takes the shape of a catenary. The current sag information refers to the difference between the height of the measuring instrument and the height of the transmission line when the measuring instrument moves to the position corresponding to the horizontal distance information, namely, if the measuring instrument is on the guide rail, the difference value is the sag value. The horizontal distance information may be determined by a range finder on the measuring instrument, i.e. the range finder emits infrared light to a receiver at the start point, whereas the current sag information may be determined by the range finder in the same way.
Step 102: the measuring instrument performs a movement in the vertical direction according to the current sag information.
When current sag information is determined, the measuring instrument moves to the transmission line below to be in contact with the transmission line according to distance data between the current sag information and the measurement instrument, and the measurement data are accurate.
Step 103: and acquiring detection data information on the measuring instrument.
The detection data information is data which are sensed on the measuring instrument and comprise factors such as resistivity, ambient temperature, wire temperature, wind speed, sunlight intensity and the like of the wire. The mode of acquisition is obtained by a sensor corresponding to factors, such as the temperature of a wire is a temperature sensor.
Step 104: and calculating corresponding current-carrying capacity information according to the detection data information.
The current-carrying capacity information is current energy information which can be carried on the wire. Current capacity informationWhere Tc is the wire temperature, t is the short load allowable time, qc is the convective heat loss, qr is the radiant heat loss, qs is the solar heat gain, and Q is the total heat capacity of the wire.
Step 105: and screening out the minimum current-carrying capacity in the current-carrying capacity information, and defining the minimum current-carrying capacity as the minimum current-carrying capacity information.
The minimum current-carrying capacity information is the minimum current-carrying capacity in the current-carrying capacity information. The temperature and radiation of the wires at different positions are different, so that the current-carrying capacity is different, the screening mode is that calculation is carried out in real time, and then the minimum value is selected.
Step 106: and calculating the capacity of dynamic capacity increase according to the minimum current-carrying capacity information, and defining the capacity as capacity information.
The capacity information is the capacity of dynamic capacity increment, and the calculation mode is numerical subtraction, namely, the minimum current-carrying capacity information changed according to the current environment is obtained by subtracting the rated current-carrying capacity information on the original power transmission line.
Step 107: and carrying out dynamic capacity expansion of the power transmission line according to the capacity information.
Referring to fig. 4, the method further includes a method for adjusting current sag information, the method including:
step 200: and acquiring guide rail height information corresponding to the horizontal distance information.
The guide rail height information is a height value of the guide rail in the horizontal distance information. The acquisition mode can be any mode which can be searched, such as a database and the like, wherein the database stores the mapping relation between the horizontal distance information and the guide rail height information. Since the rail is not easily moved or deformed, the height of the rail is fixed at the time of installation, so that it can be obtained by looking up the database. The distance meter can be arranged on the guide rail for measurement.
Step 201: and acquiring optimal temperature information without considering sag.
The optimal temperature information is the temperature information of the power transmission line which is improved under the condition of not considering sag. In order to increase the current-carrying capacity, measures are taken to increase the temperature, but after the temperature is increased, the mechanical properties of the wire are changed, the wire is lengthened, so that the sag length is lengthened, the wire is closer to the ground, and the influence of sag is generally considered when the temperature is increased, so that the temperature increase is limited. When sag is not considered, the temperature of the power transmission line can be raised more, so that the current-carrying capacity is improved. The acquisition mode can be carried out through other tests, for example, when sag is not considered, all other factors are set to be corresponding conditions, then the current-carrying capacity is increased until one of the conditions is not in accordance with the condition, and the temperature value at the moment is the temperature value corresponding to the optimal temperature information.
Step 202: and calculating corresponding optimal current-carrying capacity information according to the optimal temperature information.
The calculation method is the same as that of step 104, namely, the optimal temperature information is replaced with the temperature information in the detection data information, and the calculation is performed under the condition that the rest information is unchanged.
Step 203: and carrying out matching analysis according to the sag value stored in the preset sag database and the optimal current-carrying capacity information to determine a sag value corresponding to the optimal current-carrying capacity information, and defining the sag value as predicted sag information.
The sag information is expected to be the sag condition of the power transmission line when other factors are not changed and the power transmission line is only transported according to the optimal current-carrying capacity information. The sag database stores the mapping relation of the optimal current-carrying capacity information, the horizontal distance information and the sag, namely when a user inputs the horizontal distance information and the optimal current-carrying capacity information, the system automatically calculates the corresponding sag according to the horizontal distance information and the optimal current-carrying capacity information, and the sag is the predicted sag information. The database is the result obtained by a person skilled in the art through a plurality of experiments.
Step 204: and calculating the ground height information of the horizontal distance information corresponding to the power transmission line according to the guide rail height information and the expected sag information.
The ground height information is the height value of the power transmission line and the ground in the expected sag state. The calculation mode is that the two are subtracted.
Step 205: and comparing the ground height information with preset ground safety distance information.
The ground safety distance information is the gap distance between the wire and the ground crossing air, and when the wire is closer to the ground, the current on the wire is easy to have certain electromagnetic influence and even current influence on people on the ground, so that the wire is required to be paved above a certain height on the ground. The comparison mode is numerical comparison.
Step 2051: if the height value corresponding to the ground height information is larger than the height value corresponding to the ground safety distance information, no adjustment is performed.
If the height value corresponding to the ground height information is larger than the height value corresponding to the ground safety distance information, the current height is larger than the safety distance height, the height of the power transmission line at the position is safer, pedestrians below the power transmission line is not affected, and adjustment is not needed.
Step 2052: if the height value corresponding to the ground height information is smaller than the height value corresponding to the ground safety distance information, the guide rail height information and the ground safety distance information are calculated to obtain corresponding safety sag information.
The safety sag information is sag information corresponding to a numerical value that the distance to the ground is a safety distance after the transmission line slides up and down from the guide rail. If the height value corresponding to the ground height information is smaller than the height value corresponding to the ground safety distance information, it is indicated that if the ground height information adjusted according to the optimal temperature information cannot meet the requirement, there is a certain risk, and therefore the ground height information needs to be raised.
Step 206: and selecting a corresponding clamping device according to the horizontal distance information to adjust the power transmission line so as to adjust the current sag information into safe sag information.
As shown in fig. 4, the clamping device clamps the power transmission line to adjust up and down so as to adjust the current sag information into safe sag information, thereby ensuring that the power transmission line is located at a safe distance from the ground.
Referring to fig. 5, there is also included a control method of a clamping device, the method including:
step 300: and acquiring current wind speed information.
The current wind speed information is information of the wind speed of the power transmission line corresponding to the horizontal distance information. The mode of acquisition is a wind speed sensor.
Step 301: and calculating corresponding required supporting force information according to the current wind speed information and preset clamping device information.
The gripping device information is mechanical data information inherent to the gripping device, such as: arm length, cross-sectional area perpendicular to wind speed direction, and the required supporting force information is information of force required to be supported against the current wind speed when the transmission line is fixed at the original position. F=ρav 2 Where ρ is the air density, A is the cross-sectional area of the clamping device, and V is the current wind speed information.
Step 302: and calculating torque information of the corresponding driving piece according to the required supporting force information and the current sag information.
As shown in fig. 3, when wind is blown from both sides of the guide rail in the longitudinal direction, the power transmission line is liable to shake, whereas when wind is blown in the longitudinal direction of the guide rail, the guide rail and the power transmission line are less affected, so only wind in the vertical guide rail longitudinal direction is considered in the present application. So that only a force in the vertical direction needs to be applied to the clamping device. The torque is n=fs, where S is the arm length, and in this embodiment S is the sag corresponding to the current sag information.
Step 303: and carrying out matching analysis according to the power magnitude stored in the preset power database and the torque information to determine a power value corresponding to the torque information, and defining the power value as current power information.
The current power information is information of motor output power required for outputting corresponding torque information. The power database stores the mapping relation between the power magnitude and the torque information. The database is calculated by a person skilled in the art through experiments and empirical formulas.
Step 304: the driving piece drives according to the current power information to support the power transmission line.
The driving piece outputs according to the current power information, so that a force which counteracts the current wind speed information is provided on the clamping device, the power transmission line is always positioned below the guide rail, and the measuring instrument can be contacted with the power transmission line when moving downwards.
Referring to fig. 6, there is also provided a driving method of a driving member, the method including:
step 400: and acquiring the maximum power value in the current power information, and defining the power value as the maximum power information.
The maximum power information is information of the maximum power value in the current power information. Since the current wind speed is different in each place, the corresponding power is also different.
Step 401: and calculating the maximum power information and the optimal current-carrying capacity information to obtain the total current-carrying capacity information.
The total current information is the information of the maximum value of the current transmitted on the power transmission lines, namely, the maximum power information is output on the clamping device on each power transmission line, the movement of the mobile trolley is provided, and the current information of the use of the measuring instrument is measured. The way of calculation is the addition of the values.
Step 402: and judging whether the current power information is smaller than the maximum power information.
The judgment mode is that the numerical values are compared with each other. The purpose of the judgment is to determine whether the current power information corresponding to the horizontal distance information can consume a part with more current carrying capacity.
Step 4021: if the current power information is smaller than the maximum power information, calculating a difference between the current power information and the maximum power information, and defining the difference as first difference information.
The first difference information is the difference between the current power information and the maximum power information, and if the current power information is smaller than the maximum power information, the current on the power transmission line is larger than the power required by the current line.
Step 4022: if the current power information is equal to the maximum power information, only the driving member and the clamping device are supplied with power.
If the current power information is equal to the maximum power information, the maximum power information is directly output, and no redundant electric energy exists.
Step 403: and carrying out dynamic capacity expansion of the power transmission line according to the total current capacity information, supplying power to the driving piece and the clamping device according to the current power information, and storing the current quantity corresponding to the first difference information in a storage battery corresponding to the current power information.
Because the current power information is smaller than the maximum power information, the power provided on the clamping device is larger than the current power information, and a certain margin is provided. These margins are stored in the battery.
Referring to fig. 7, another driving method of a driving member is also included, the method including:
Step 500: and acquiring an average value in the current power information, and defining the power as average power information.
The average power information is information of an average value in the current power information. The current power information corresponding to each clamping device is summed and averaged.
Step 501: and calculating the average power information and the optimal current-carrying capacity information to obtain the average current-carrying capacity information.
The average current-carrying capacity information is information of an average value of the transmission current-carrying capacity on the transmission lines, namely, average power information is output on a clamping device on each transmission line, movement of a mobile trolley is provided, and the current-carrying capacity information of the use of the measuring instrument is provided. The way of calculation is the addition of the values.
Step 502: and judging whether the current power information is smaller than the average power information.
The judgment mode is that the numerical values are compared with each other. The purpose of the judgment is to determine whether the current power information corresponding to the horizontal distance information can consume a part with more current carrying capacity.
Step 5021: if the current power information is smaller than the average power information, calculating a difference between the current power information and the average power information, and defining the difference as second difference information.
The second difference information is a difference between the current power information and the average power information when the current power information is smaller than the average power information. If the current power information is smaller than the average power information, the power provided by the power transmission line at the moment has a margin.
Step 5022: if the current power information is equal to the average power information, only the driving piece and the clamping device are powered.
If the current power information is equal to the average power information, the current power information is just equal, and the output is only used for the driving piece and the clamping device to maintain power supply.
Step 5023: if the current power information is larger than the average power information, calculating a difference between the average power information and the current power information, and defining the difference as third difference information.
The third difference information is a difference between the average power information and the current power information when the current power information is greater than the average power information. If the current power information is larger than the average power information, the power provided by the power transmission line at the position cannot meet the current power.
Step 503: and carrying out dynamic capacity expansion of the power transmission line according to the average current capacity information, supplying power to the driving piece and the clamping device according to the current power information, and storing the current quantity corresponding to the second difference information in a storage battery corresponding to the current power information.
Since there are margins, these margins are stored in the secondary battery.
Step 504: the storage battery provides power corresponding to the third difference information for the driving piece and the clamping device and combines the current power information to supply power for the driving piece and the clamping device.
Because the current power cannot be met, the storage battery is required to supply power so as to ensure that the current power information can be met.
Referring to fig. 8: also included is a method of powering a battery, the method comprising:
step 600: and acquiring electric quantity information of the storage battery corresponding to the horizontal distance information.

Step 601: and carrying out matching analysis according to the movement time length of the measuring instrument corresponding to the preset movement time length database and the horizontal distance information to determine the movement time length corresponding to the horizontal distance information, and defining the movement time length as movement time length information.
The movement time length information is the time length when the measuring instrument moves forward along the guide rail at a certain speed and then returns to the position. The mobile time length database stores the mapping relation between the current position and the corresponding mobile direction and mobile time length. The database can be calculated by a calculation formula or can be obtained by a tester through a test. Namely, when the user inputs the horizontal distance information, the corresponding movement duration information is also automatically output.
Step 602: and calculating according to the movement duration information and the third difference information to obtain the estimated power consumption information.
The estimated power consumption information is output by the third difference information output by the current storage battery, and the time length output after the upper mobile trolley starts to move from the current position and returns to the current position is the power consumption value when the time length is the mobile time length information.
Step 603: and comparing the electric quantity information with the expected consumed electric quantity information.
The comparison between the two is numerical comparison.
Step 6031: if the electric quantity value corresponding to the electric quantity information is larger than the electric quantity value corresponding to the estimated consumed electric quantity information, the measuring instrument continues to move.

Step 6032: and if the electric quantity value corresponding to the electric quantity information is smaller than the electric quantity value corresponding to the estimated consumed electric quantity information, the storage battery is replaced by the full-charge storage battery by the manipulator which moves along with the measuring instrument.
If the electric quantity value corresponding to the electric quantity information is smaller than the electric quantity value corresponding to the estimated consumed electric quantity information, the electric quantity on the storage battery is not supported until the test instrument starts from the current position to returns to the current position, the storage battery is replaced by a full-electric storage battery at the moment, and the full-electric storage battery has a large capacity and can adhere to at least one line. The mobile trolley is provided with a full-power storage battery or a storage battery with electric quantity close to full power.

step 700: and calculating the electric quantity information and the preset full electric quantity information to obtain supplementary electric quantity information.
The supplementary electric quantity information is the electric quantity which can be supplemented when the current electric quantity information reaches the full electric quantity information.
Step 701: and calculating according to the movement duration information and the second difference information to obtain the estimated increased electric quantity information.
The estimated charge amount increasing information is the charge amount increasing value obtained when the second difference information output by the current storage battery is used for storing power, and the upper mobile trolley starts to move from the current position and returns to the current position, namely the charge amount increasing value is obtained when the charge period is stored as the movement period information. The way of calculation is a multiplication of the two.
Step 702: and comparing the supplementary electric quantity information with the estimated electric quantity increase information.
The comparison is numerical comparison, and the aim of the comparison is to determine whether the two parts are full.
Step 7021: if the electric quantity value corresponding to the supplementary electric quantity information is larger than the electric quantity value corresponding to the estimated increase electric quantity information, the measuring instrument continues to move.
If the electric quantity value corresponding to the supplementary electric quantity information is larger than the electric quantity value corresponding to the predicted electric quantity increase information, the battery is not fully charged, and the battery is not easy to explode due to continuous charging after the electric quantity is fully charged.
Step 7022: if the electric quantity value corresponding to the supplementary electric quantity information is smaller than the electric quantity value corresponding to the estimated increase electric quantity information, the storage battery is replaced by an empty storage battery by the manipulator moving along with the measuring instrument.
