Description
Technical field
The present invention relates to switching equipment technology, particularly a kind of gas-insulated metal-enclosed based on ant group algorithm opens
Close equipment processing method and Cubicle Gas-Insulated Switchgear.
Background technology
Cubicle Gas-Insulated Switchgear GIS (Gas Insulated Switchgear) is by breaker, isolation
The main elements such as switch, earthing switch, busbar, mutual inductor, arrester are packed into the metal shell of sealing, are asked and are filled with insulation gas
Body is as insulation and arc-extinguishing medium.Traditional GIS device is mainly using SF6 as insulation and arc-extinguishing medium, and SF6 is with very long
Atmospheric lifetime and very strong infrared-ray adsorption capacity, therefore with high GWP (greenhouse effects coefficient), it is about CO2's
23900 times, it is one of an important factor for causing global warming, therefore the present invention use environment-friendly type gas as the gas that insulate
Body.
But there is also Railway Projects during using environment-friendly type gas：(1) saturation of environment-friendly type gas at the working temperature in GIS
Vapour pressure is relatively low, it is therefore necessary to and the gas mixing use that saturated vapour pressure is high, this will consider two or three of different gas
The mixed proportion problem of body, and the variation of the difference of mixed proportion and air pressure height can all influence the temperature field inside GIS；
(2) environment-friendly type gas is used to insulate in GIS, and the fine or not degree of insulation performance depends on the uniform journey of internal electric field distribution
Degree, this requires internal structure is optimized；(3) pressure of SF6 gases is 0.5MPa in traditional equipment, and environmentally friendly
Gas pressure is in 0.7-0.8MPa in type GIS, and after the modification carried out on the basis of (2) to structure, total
Stress can also change correspondingly.

A kind of pheromones can be discharged on the path that it is passed by, the amount of institute's release pheromone walks the length in path with it and is inversely proportional, i.e.,
The path that ant walks is shorter, and the pheromones stayed on path are more；Conversely, the path that ant is passed by is longer, pheromones are stayed
It will be fewer.There is certain guidance to make when selection path after these pheromones also have other ants the ant in itself
With in general, ant is invariably prone to the higher path movement of selection pheromone concentration.Therefore work as what is passed through on a certain paths
When ant number is more, the pheromone concentration that all ants leave on the path will be very big, and later ant selects this road
The probability in footpath will be bigger, as more and more ants select the path, the intensity of the pheromones in the path will progressively by
Increase.Ant not necessarily walks sometimes along the high path of messenger substance amount, it is also possible to the other paths of search, if search
To after shorter path, ant again can be toward drawing close on shorter path.Finally, most ants work on shortest paths.Ant colony
Algorithm is drawn by positive feedback mechanism and probability diversity by the most short of this n urban node using virtual ant individual
Path length.Ant group algorithm can optimize Cubicle Gas-Insulated Switchgear.
