To achieve these goals, the utility model adopts following technical scheme:

A kind of miniaturization Cubicle Gas-Insulated Switchgear comprises that underframe, circuit breaker are with mechanism case, convergence control cabinet and breaker body; Circuit breaker is connected with breaker body with mechanism case; Convergence control cabinet connects circuit breaker through sealing device and uses mechanism case; The convergence control cabinet bottom links to each other with underframe through crash roll, and sealing device fixedly is assemblied in the seam crossing of circuit breaker with mechanism case and convergence control cabinet.

Said miniaturization Cubicle Gas-Insulated Switchgear also comprises first main bus bar, first group of isolating switch, first group of current transformer, second main bus bar, first group of transition shell and inner conductor, second group of isolating switch, second group of transition shell and inner conductor and second group of current transformer; First main bus bar and second main bus bar are fixed on the underframe, and first group of current transformer links to each other with breaker body with second group of current transformer; First group of isolating switch links to each other first group of current transformer through bolts assemblies with first main bus bar; Connect second group of isolating switch between first group of transition shell and inner conductor and second group of transition shell and the inner conductor, second group of transition shell and inner conductor connect second group of current transformer, and first group of transition shell and inner conductor connect second main bus bar.

Convergence control cabinet and circuit breaker are with the adjacent setting of mechanism case.

With respect to prior art; The utlity model has following advantage: the utility model is under the situation that does not change the product assembling, detects, keeps in repair; The protection separation of raw-gas insulated metal sealing switch equipment (GIS) has been carried out comprehensive optimization to be improved; Reduce sealing surface, thereby make the switchgear of same function succinct more, reliable, effectively reduced safety of products hidden danger; Reduced product cost simultaneously, reduced product assembling, detection, maintenance difficulty simultaneously, made product have more aesthetic property, economy; The casing integrated setting has been optimized the product structure of GIS, has realized the product structure simplification, has promoted the good looking appearance degree of product, has improved reliability of products simultaneously.The utility model has been realized reducing of gas-insulated metal enclosed switchgear (GIS) equipment integral size, greatly reduces the manufacturing cost and the cost of transportation of product.More original product has had lifting by a relatively large margin on product design, makes product one integrated mass in shape.As control unit, the utility model not only makes product on a body construction, realize simplifying, and in secondary control, realizes the unified management and the layout of secondary component, makes product to integrated, intelligent direction development.
