It should be noted that, when acquiring the parameter information of the charged portion, the geometric information of the charged portion and the geometric information of the grounded portion, the parameter information may be acquired synchronously or may be performed step by step. And when a step-by-step execution mode is adopted, the acquired sequence can be flexibly set according to the actual situation, and the method is not particularly limited.
Specifically, referring to fig. 1, step S100 is first executed to obtain a live portion and a ground portion in a three-dimensional model of a substation.
In one possible implementation, the live part and the ground part may be set by a designer in a generic model of a substation and the safe distances required by the relevant standard specifications are built into a database, for example, in a substation, a transformer is set as the live part, an electric box is set as the ground part, and a fixed safe distance value is set according to the phase and voltage level of the live part and stored in the database. And then, acquiring a live part and a grounding part preset by a transformer substation model, wherein the transformer substation three-dimensional model comprises parameter information and geometric information, the geometric information comprises coordinate information of the live part and the grounding part in the transformer substation three-dimensional model, and the parameter information comprises at least one of phase and voltage grade of the live part.

And then matching the parameter information with a safe distance data set to obtain a safe distance, wherein the parameter information comprises the characteristics of the charged part, acquiring the parameter information, matching the parameter information with the data marks of the safe distance data in the safe distance data set, and extracting the safe distance data matched with the parameter information from the safe distance data set as the currently required safe distance. The safety distance data set comprises a plurality of safety distance data, each safety distance data is accompanied by a data mark, and the data marks are used for representing the charged parts corresponding to the safety distance data. It should be noted that, when the corresponding data mark is set for each safety distance data, the set data mark may include the characteristic of the charged part, so that the data mark and the parameter information can be matched correspondingly. Such as: the characteristic of the charged portion includes V1(V1 is the voltage of the charged portion), and the parameter information set according to the characteristic includes V1. The data flag in the safety distance data corresponding to the charged part is denoted by V1. Therefore, the currently required safety distance can be determined according to the corresponding matching of the parameter information V1 and the data mark V1.
Further, after the safety distance is obtained, step S300 may be executed to obtain the geometric information of the live portion and the geometric information of the ground portion from the three-dimensional model of the substation, and calculate and obtain the shortest distance between the live portion and the ground portion according to the geometric information of the live portion and the geometric information of the ground portion.
In a possible implementation manner, an electrified part and a grounding part exist in a transformer substation model, and a first triangular surface of the grounding part and a second triangular surface of the electrified part are obtained; the first triangular surface is a triangular surface in the bounding box of the grounding part, and the second triangular surface is a triangular surface in the bounding box of the charged part; the number of the first triangular surfaces and the number of the second triangular surfaces are multiple, the distance between each first triangular surface and each second triangular surface is calculated respectively to obtain multiple triangular surface distances, and the distance with the minimum numerical value is extracted from the multiple triangular surface distances to be used as the shortest distance. For example, if the first triangular surface includes a triangular surface a, a triangular surface b, and a triangular surface c, and the second triangular surface includes a triangular surface m and a triangular surface n, the distances from the triangular surface m to the triangular surface a, the triangular surface b, and the triangular surface c are calculated, the distances from the triangular surface n to the triangular surface a, the triangular surface b, and the triangular surface c are calculated to obtain six distances, and the shortest distance is selected from the six distances.
In a possible implementation manner, if one live part and a plurality of ground parts exist in the substation model, the triangular surface of each ground part and the triangular surface of each live part are obtained, the number of the triangular surfaces is multiple, the distance between the triangular surface of each live part and the triangular surface of each ground part is respectively calculated, a plurality of triangular surface distances are obtained between each live part and each ground part, and the distance with the smallest value is extracted from the plurality of triangular surface distances to be used as the shortest distance, so that a plurality of shortest distances are obtained. For example, there are a charged portion a and a grounded portion B, a grounded portion C, and a grounded portion D, and each triangular surface of the charged portion a and the grounded portion B, the grounded portion C, and the grounded portion D is obtained, the distance between each triangular surface of the charged portion a and the grounded portion B is first calculated, the shortest distance is obtained from a plurality of distances, then the shortest distance between the charged portion a and the grounded portion C, and the charged portion a and the grounded portion D is calculated, three shortest distances are obtained, and the calculation method of the shortest distance is the same as the calculation method of the shortest distance between the charged portion a and the grounded portion B, and is not described herein again.
In another possible implementation manner, if a plurality of live parts and a plurality of ground parts exist in the substation model, the live parts and the ground parts are in one-to-one correspondence, triangular surfaces of the live parts and the ground parts are obtained, distances between the triangular surfaces of the corresponding live parts and the corresponding ground parts are calculated respectively, and the shortest distance is selected from the distances between each pair of the live parts and the ground parts to obtain a plurality of shortest distances. For example, there are a charged portion Q, a charged portion M, a charged portion N and a grounded portion X, a grounded portion Y, and a grounded portion Z, and the shortest distances of the charged portion Q and the grounded portion X, the grounded portion Y, and the grounded portion Z are calculated, respectively, the shortest distances of the charged portion M and the grounded portion X, the grounded portion Y, and the grounded portion Z, and the shortest distances of the charged portion N and the grounded portion X, the grounded portion Y, and the grounded portion Z are calculated, to obtain nine shortest distances, wherein the calculation method of the shortest distances is the same as the calculation method of the shortest distances of the charged portion a and the grounded portion B, and will not be described herein again.
It should be noted that the distance from the triangular surface to the triangular surface may be calculated by a conventional distance calculation method in the art, and details are not described here.
After the shortest distance is obtained, step S400 may be executed to compare the safe distance with the shortest distance, and obtain a corresponding verification result according to a size relationship between the safe distance and the shortest distance.
In a possible implementation manner, a live part and a grounding part exist in the transformer substation model, triangular surfaces of the live part and the grounding part are obtained, the distance from the triangular surface of the live part close to the grounding part to the triangular surface of the grounding part close to the live part is calculated to obtain the shortest distance, the obtained safety distance is compared with the shortest distance, and if the shortest distance is greater than the safety distance, the distance between the grounding part and the live part is safe.
In another possible implementation manner, if a plurality of live parts and a plurality of ground parts exist in the substation model, the live parts and the ground parts are in one-to-one correspondence, triangular surfaces of the live parts and the ground parts are obtained, distances between the triangular surfaces of the corresponding live parts and the corresponding ground parts are calculated respectively, and the shortest distance is selected from a plurality of distances between each live part and the corresponding ground part thereof to obtain a plurality of shortest distances. If the shortest distance is less than or equal to the safe distance, i.e., the distance between the grounded portion and the charged portion is too close, it is not within the safe range. And then recording position points of all the electrified parts and the grounding parts which do not meet the requirement of the safety distance (namely marking the electrified parts and the grounding parts which do not meet the requirement of the safety distance), wherein the recorded position points are used for accurately positioning problem positions, and the problem positions are convenient for workers to determine.
In addition, the center of the charged part can be used as the center of the sphere, the safe distance is obtained from the database according to the parameter information, the sphere representing the radiation range of the safe distance is constructed by taking the safe distance as the radius, and finally, whether any grounding part exists in the sphere range is judged, if the grounding part exists in the sphere range, the charged part and the grounding part do not meet the requirement of the safe distance, and if the grounding part does not exist in the sphere, the requirement of the safe distance is met.
It should be noted that, although the substation safety clear distance verification method is described above by taking the above steps as examples, a person skilled in the art can understand that the disclosure should not be limited thereto.
