Embodiment 1
[0032] Such as figure 1 As shown, it is a compact self-energy gap arc extinguishing lightning protection device, which is composed of an upper arm and a lower arm 1 and an air gap 2 formed between the upper arm and the lower arm 1; as Figure 4 As shown, the upper arm is composed of one end of a transverse arm 3 and one end of a longitudinal arm 4 connected by a bolt 6, as Figure 5 As shown, the other end of the transverse arm 3 is connected to the upper end of the insulator string 5 through a diamond buckle 7, one end of the lower arm 1 is connected to the lower end of the insulator string through a diamond buckle 7, and the other end of the lower arm 1 is connected to the longitudinal arm An air gap 2 is formed between the other ends of 4; the length of the air gap 2 is 60mm; the lower arm 1 is made of galvanized steel rod, and its length is 700mm.
[0033] The transverse arm 3 and the longitudinal arm 4 are composed of a plurality of arc extinguishing chamber units 8 conn...
experiment example 1
[0039] The implementation effect of the compact self-energy gap arc extinguishing and lightning protection device of the present invention is further illustrated by the simulation experiment and the quenching impact arc test of the multi-chamber arc extinguishing structure.
[0040] 1. Simulation experiment
[0041] Use COMSOL Mutiphsics software to build a simulation model of the semi-closed self-energy arc extinguishing chamber structure, simulate and analyze the motion characteristics of the arc in the chamber, and verify the air blowing of the compact self-energy gap arc extinguishing lightning protection device prepared in Example 1 of the present invention For the effect of arc extinguishing, take Example 1 as experimental example A, and use a conventional gap arc extinguishing lightning protection device without a constriction structure as comparative example B.
[0042] Such as Figure 6 Shown is the time-varying curves of the airflow velocity in the chambers of A and B...
