Embodiment Construction

[0020] As can be seen from Figure 1, the method for realizing the safe net distance of the power distribution device in three-dimensional space of the present invention includes the following steps:

[0021] a. Set up the power distribution device parameter database. The data information in the power distribution device parameter database matches the content of the high-voltage power distribution and distribution device design specification DL / T5352-2006. For example, the content included in the power distribution device parameter database: power distribution device name, model, application environment (that is, installation site, outdoor power distribution device / indoor power distribution device), scope of application (such as between the live part and the grounding part, no Between the shielded bare conductor and the ground, between the upward extension line of the mesh shield 2.5M from the ground and the live part above the shield, etc.), the rated voltage and the live safe...

Abstract

The invention relates to the field of electric power engineering three-dimensional design, in particular to a method for realizing a safe clear distance of a power distribution unit in three-dimensional space. By setting a power distribution unit parameter database and power distribution unit indexes and reading a corresponding charged safety radius value of the power distribution unit in the power distribution unit parameter database, a spherical virtual charged area can be generated by taking the selected power distribution unit charged point as the center of a circle and taking the chargedsafety radius value as the radius. Due to the adoption of the technical scheme, the safe clear distance of the power distribution unit can be simply and clearly expressed in a three-dimensional design system, and the power distribution unit can be adjusted according to results.

Description

technical field [0001] The invention relates to the field of three-dimensional design of electric power engineering, in particular to a method for realizing the safe net distance of a power distribution device in three-dimensional space. Background technique [0002] At present, in the process of two-dimensional graphic design, the safe area of ​​the power distribution device is still judged artificially, and it is very easy to overlap the safe area. If it is less than the phase spacing, it may cause a phase-to-phase short circuit. If it is less than the ground distance, it may cause a ground short circuit. , if it is less than the safe distance to people, it will definitely cause electric shock to the human body. The three-dimensional design system (AVEVA PDMS) is widely used in the power design industry. PDMS 3D software can enable the engineering and power industry to complete high-quality plant design with the least cost and the lowest risk. It uses Microsoft's .NET tech...
