Method for detecting various safety belt electric clearances based on model attributes

Abstract

The invention provides a method for detecting various safety belt electric clearances based on model attributes. The method comprises the steps of establishing a three-dimensional verification space;facility classification and assignment; generating and correcting an inspection result; generating a virtual clear distance space; performing cross detection; deriving electronic browsing format reports. According to the scheme, verification can be carried out according to different minimum safety clear distance verification types, verification distance errors of different safety clear distance classifications are eliminated, the quality of designed finished products can be optimized, the design efficiency is improved, and engineering operation, construction and maintenance safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation design, in particular to a detection method for multiple types of safe liveline clearance distances based on model attributes. Background technique [0002] The minimum safety net distance refers to the minimum distance between the live part and the external parts and the human body without discharge or electric shock accidents, including a variety of safety verification categories: between the live part and the grounding part, between live parts of different phases, and without obstruction between bare conductors and ground, etc. The minimum safety net distance check of power distribution devices is an important link in power transmission and transformation projects. The safety distance verification under the circumstances can directly affect whether the design scheme is established or not. At the same time, the minimum safety net distance verification also involve...

Problems solved by technology

Since the current 3D design software does not have an independent design for the minimum safety clearance verification, it cannot analyze the classification of the factory, the charged body facilities in the station, and other auxiliary facilities. It is necessary to manually judge the attributes of various facilities in the project, and then calculate and calibrate Inspection work, the process is complex, error-prone, there are great safety hazards, seriously affecting the quality of the design product

Specifically, through the collision inspection of the 3D model entities of the facilities in the factory and station, the facilities do not contain attributes and cannot be classified, so the existing technology cannot perform verification according to all classifications required in the specification, and there are types and scopes of verification Limitations: Designers are required to subjectively judge whether there are unsatisfactory conditions. There are hundreds of calibration positions in the project, resulting in a high rate of manual operation errors; calibration values ​​cannot be automatically generated through altitude correction, which affects the efficiency of the minimum safe clearance calibration ;The verification results cannot be summarized uniformly, resulting in the loss of key information during the modification process
