Description
Technical field
The utility model relates to power supply equipment technical field, particularly relates to a kind of GIS circuit breaker.
Background technology
110kV gas-insulated metal-enclosed switchgear has become the widely used high-voltage electrical equipment of domestic electrical power trans mission/distribution system, comes into operation in a large number in the whole nation.But because traditional power station or transformer station's floor space are large, the construction period is long.Particularly in city, power load constantly increases, and transformer station's demand rises year by year, and this just requires that a kind of novel transformer station gives birth at once.In this case, preassembled transformer station is in the sight of people, and this floor space is little, and the construction period, short new-type transformer station solved above problem.But because traditional primary voltage grade is mostly 110kV, therefore 110kVGIS just becomes a nucleus equipment of preassembled transformer station.And the core of GIS is exactly circuit breaker, but traditional 110kVGIS circuit breaker assembling can not adapt to this novel transformer station, because it requires that all controller switching equipments are contained in a casing, consider the problem of transport, which limits the size of box house equipment, and GIS relatively other equipment, is a large-scale equipment, this just requires that its assembling mode is convenient, flexibly, uses extensively.
Utility model content
The utility model aims to provide a kind of GIS circuit breaker, and can install flexibly in casing, floor space is few.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of GIS circuit breaker, comprise Shell of circuit breaker, there are conversion conductor A, conversion conductor B, upper supportive conductors A, upper supportive conductors B, upper supportive conductors C and lower support conductor in described Shell of circuit breaker inside; Described upper supportive conductors A, upper supportive conductors B, upper supportive conductors C vertically arrange and successively, point-blank transversely arranged, described upper supportive conductors A, upper supportive conductors B are connected with the venthole of 3 lower support conductors respectively with the air inlet of upper supportive conductors C, described conversion conductor A is connected with upper supportive conductors A, described conversion conductor B is connected with upper supportive conductors C, and described Shell of circuit breaker is provided with incoming line and line outlet.Upper supportive conductors A, upper supportive conductors B, upper supportive conductors C vertically arrange and successively, point-blank transversely arranged, air inlet is arranged in parallel, form airflow convection with lower support conductor gas outlet, and air-flow can not disturbs mutually.
Preferably, described incoming line is located at Shell of circuit breaker bottom, and described line outlet is located at Shell of circuit breaker top.
Preferably, described line outlet opening direction is parallel with the orientation of upper supportive conductors C with upper supportive conductors A, upper supportive conductors B.
