Abstract
The utility model provides a fixed type switch cabinet, belonging to the technical field of components of a transformer station of a switch device, especially relating to a high voltage switch cabinet. The fixed type switch cabinet is small in size and simple in operation and is reliable. The fixed type switch cabinet comprises a cabinet body, inside the cabinet body there are orderly provided an isolation switch, a vacuum breaker and a current transformer from top to down, and fixed type switch cabinet is characterized in that the isolation switch is a GN24 type isolation switch.
Description
Technical field
the utility model belongs to the parts technical field of transformer station or switching device, relates in particular to a kind of high-tension switch cabinet.
Background technology
switch cubicle is a kind of electric equipment, and it is the manufacturing important component part of power transmission and transforming equipment, in whole power industry, occupies important status.
are present, and the fixed switch cubicle of GG1A type is that the user generally uses.Its shortcoming is that volume is big, and the main element of employing is many, and size is: high 2800mm, wide 1200mm, dark 1200mm.Because its switch that adopts and mechanism are splits, reliable transmission property is poor.
secondly, the isolating switch that the fixed switch cubicle of GG1A type adopts is a GN19 type isolating switch, this isolating switch does not have the function of earthed switch.
in addition, the primary cut-out of the fixed switch cubicle of GG1A type adopts oil-minimum breaker and CD10 type dc operation mechanism, these two kinds of products mate difficult.And oil leakage phenomenon, not environmental protection often appear in switch.
Summary of the invention
the utility model is exactly to the problems referred to above, provides that a kind of volume is little, simple to operate, reliable fixation formula switch cubicle.
are for realizing above-mentioned purpose; The utility model adopts following technical scheme; The utility model comprises cabinet, is connected with isolating switch, vacuum circuit-breaker, current transformer in the cabinet from top to bottom in turn, and its structural feature isolating switch adopts GN24 type isolating switch.
as a kind of preferred version, the said vacuum circuit-breaker of the utility model adopts ZN63 type vacuum circuit-breaker.
the utility model beneficial effect: GN24 type isolating switch also has the function of earthed switch except the function with isolating switch.It adopts the twin shaft linkage work, so in the operating process, in the isolating switch separating brake, also earthed switch is closed a floodgate.In minute ground connection switch, also with the isolating switch lock that closes.Operation not only simply but also reliable.Simultaneously, exempt to have used earthed switch again, reduced manufacturing cost.
secondly because the utility model member is few, corresponding kit is also few, the use amount of copper bar has also reduced, and therefore greatly reduces manufacturing cost.
in addition, the element that the utility model uses is few, the fault point is also few, has also reduced maintenance cost.
the utility model cabinet size can be accomplished: high 2100mm, wide 950mm, dark 900mm.Than the fixed switch cubicle of GG1A type, volume-diminished 2.24 times.
Description of drawings
further specify the utility model below in conjunction with accompanying drawing and embodiment.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model end view.
Among
figure, 1 is current transformer, and 2 is that vacuum circuit-breaker, 3 is that cabinet, 4 is isolating switch.
Embodiment
are as shown in the figure, and the utility model comprises cabinet 3, are connected with isolating switch 4, vacuum circuit-breaker 2, current transformer 1 in the cabinet 3 from top to bottom in turn, and isolating switch 4 adopts GN24 type isolating switch.
said vacuum circuit-breaker 2 adopts ZN63 type vacuum circuit-breaker.ZN63 type vacuum circuit-breaker integrates switching mechanism, both matees fully, and performance is very reliable again; And environmental protection, simple to operate.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection range of the utility model.
Claims (2)
1. a fixed switch cubicle comprises cabinet (3), is connected with isolating switch (4), vacuum circuit-breaker (2), current transformer (1) in the cabinet (3) from top to bottom in turn, it is characterized in that isolating switch (4) adopts GN24 type isolating switch.
