As shown in Figures 1 to 4, the mechanical calculation tool for electrical circuit devices provided by this invention includes a data input module, a calculation processing module, and a result output module. The data input module is used to acquire the initial parameters of the electrical circuit device to be processed (such as a conductor, insulator string, etc.) and transmit the initial parameters to the calculation processing module. The calculation processing module is used to calculate the mechanical parameters of the electrical circuit device to be processed based on the initial parameters and transmit the mechanical parameters to the result output module. The result output module is used to output the mechanical parameters.

[0023] In a specific embodiment of the present invention, the initial parameters include operating condition parameters, device parameters, and initial load parameters. The operating condition parameters mainly include environmental parameters during normal use and during installation and maintenance of the electrical circuit device to be treated, such as temperature range (from minimum to maximum temperature), wind speed range (from minimum to maximum wind speed), icing thickness, etc. The electrical circuit device to be treated includes the conductor to be treated and the insulator string to be treated. The device parameters include conductor parameters and insulator string parameters. The conductor parameters include conductor type, conductor diameter, conductor unit weight, conductor cross-sectional area, conductor elastic modulus, conductor rated breaking force, conductor temperature expansion coefficient, etc. The insulator string parameters include insulator string type, number of insulator discs, weight of a single disc, structural height of a single disc, hardware weight, hardware length, total string weight, total string length, etc. The initial load parameters mainly include the load on the electrical circuit device to be treated (including the conductor to be treated and the insulator string to be treated) from other loads (such as down conductors, maintenance loads, etc.), denoted as concentrated load parameters.

The modified load calculation submodule is used to calculate the modified load parameters of the electrical circuit device under different operating conditions based on the operating condition parameters, the device's own parameters, and the initial load parameters. It should be noted that for the electrical circuit device being processed, the concentrated load parameter is the load on the device under ideal conditions (without considering the operating environment) from other loads (such as down conductors, maintenance loads, etc.). In actual calculations, considering different operating environments and the weight of the electrical circuit device itself, the overall load of the electrical circuit device under different operating conditions can be calculated based on the operating condition parameters, the device's own parameters, and the initial load parameters, and this is recorded as the modified load parameter.

[0025] It should also be noted that conductors and insulators have different parameter types, therefore, different calculation formulas are needed to calculate the corresponding corrected load parameters based on the specific parameters of the devices.

[0026] Furthermore, the torque and load factor calculation submodule is used to calculate the torque and load factor of the electrical circuit device under different operating conditions based on the corrected load parameters of the electrical circuit device under different operating conditions. It should be noted that the torque and load factor of the electrical circuit device are intermediate parameters for the transition from the load parameters to the mechanical parameters of the electrical circuit device. By calculating the torque and load factor of the electrical circuit device based on the corrected load parameters of the electrical circuit device under different operating conditions, it is convenient to calculate the corresponding mechanical parameters accurately and efficiently in the future.

[0027] Furthermore, after calculating the torque and load factor of the electrical circuit device under different operating conditions by calculating the corrected load parameters of the electrical circuit device under different operating conditions, the mechanical parameter calculation submodule is used to calculate the mechanical parameters (such as stress, tension, sag, etc. under different operating conditions) of the electrical circuit device under different operating conditions based on the torque and load factor of the electrical circuit device under different operating conditions.

[0028] In a specific embodiment of the present invention, the mechanical parameters include device mechanical parameters (mainly related to the device itself); and the mechanical parameter calculation submodule includes a device mechanical parameter calculation unit (mainly related to the device itself); wherein, the device mechanical parameter calculation unit is used to calculate the device mechanical parameters of the electrical circuit device under different operating conditions based on the torque and load factor of the electrical circuit device under different operating conditions.

[0029] It should be noted that, for the electrical circuit devices to be processed, in actual use, they are all constructed through an architecture. In order to clearly calculate all the mechanical parameters related to the electrical circuit devices to be processed, in another preferred embodiment of the present invention, the initial parameters also include architecture initial parameters. These mechanical parameters include not only the mechanical parameters of the devices but also the mechanical parameters of the architecture. Furthermore, the mechanical parameter calculation submodule also includes an architecture mechanical parameter calculation unit. The architecture mechanical parameter calculation unit is used to calculate the architecture mechanical parameters of the electrical circuit devices to be processed under different operating conditions based on the torque and load factor of the electrical circuit devices under different operating conditions and the corresponding architecture initial parameters.

[0030] Specifically, the architecture mechanical parameters include lateral architecture mechanical parameters; and the architecture mechanical parameter calculation unit includes a lateral (i.e., transverse) architecture mechanical parameter calculation subunit; wherein, the lateral architecture mechanical parameter calculation subunit is used to calculate the lateral architecture mechanical parameters of the electrical circuit device under different operating conditions based on the mechanical parameters of the electrical circuit device itself. Furthermore, the architecture mechanical parameters also include vertical architecture mechanical parameters; and the architecture mechanical parameter calculation unit also includes a vertical architecture mechanical parameter calculation subunit; wherein, the vertical architecture mechanical parameter calculation subunit is used to calculate the vertical architecture mechanical parameters of the electrical circuit device under different operating conditions based on the mechanical parameters of the electrical circuit device itself.

[0031] It should be noted that the horizontal structural mechanical parameters are mainly used to characterize the mechanical parameters of the electrical circuit device under different operating conditions in the horizontal direction, while the vertical structural mechanical parameters are mainly used to characterize the mechanical parameters of the electrical circuit device under different operating conditions in the vertical direction.

[0032] In another preferred embodiment of the present invention, to facilitate the observation of the mechanical parameters of the electrical device under various operating conditions by the operator, the result output module may include a display subunit for displaying the mechanical parameters. Furthermore, to facilitate the storage and retrieval of all data within the tool, the electrical circuit device mechanical calculation tool provided by the present invention also includes a parameter library for storing the initial parameters and the mechanical parameters, so that the relevant initial parameters and mechanical parameters can be retrieved at any time.

[0033] On the other hand, to further illustrate the usage process of the mechanical calculation tool for electrical circuit devices provided by the present invention, the present invention also provides a method for using the aforementioned mechanical calculation tool for electrical circuit devices, the method comprising: obtaining initial parameters of the electrical circuit device to be processed; calculating the mechanical parameters of the electrical circuit device to be processed based on the initial parameters; and outputting the calculated mechanical parameters.
