Abstract
The utility model relates to a GIS (gas insulated switchgear) combined electrical appliance, in particular to a 110kV GIS combined electrical appliance which is suitable for VT (voltage transformer)-LA (lightning arrester) guard interval, comprises a lightning arrester and a voltage transformer and belongs to the technical field of power supply equipment. The GIS combined electrical appliance comprises a main busbar, an isolating switch is fixedly connected at the upper end of the main busbar, and the two sides of the isolating switch are respectively fixedly connected with the voltage transformer and the lightning arrester; and the isolating switch, the main busbar, the voltage transformer and the lightning arrester commonly form a T-shaped structure. The GIS combined electrical appliance has the advantages of simplicity, aesthetics, symmetrical and balanced integral arrangement, and capability of greatly reducing integral height, the position of an operating mechanism for the isolating switch and a grounding switch is also greatly reduced, and manual operation is facilitated; and a three-way housing and a four-way housing are not required, and the cost can be greatly saved.
Description
Technical field
The utility model relates to a kind of GI S combined electrical apparatus, and the especially a kind of VT-LA of being applicable to protection 110kV GIS combined electrical apparatus at interval, that contain lightning arrester and voltage transformer belongs to the power supply unit technical field.
Background technology
Under the external environment that GIS combined electrical apparatus manufacturer sharply increases,, practice thrift into the primary work that original increase competitiveness has become current each producer how through reduction procedure.As shown in Figure 1; The existing 110kV GIS combined electrical apparatus that contains lightning arrester mainly adopts vertical arrangement; Main bus bar M top links to each other with the isolating switch DS that has earthed switch ES and FES through three-way body, and isolating switch DS links to each other with the four-way housing, and lightning arrester LA is equipped with in the voltage transformer VT, the below that are connected with upside-down mounting above the four-way housing; Lightning arrester LA through stent support on underframe, more than all parts all be positioned at the same side of on-site control LCP.The problem that this combined electrical apparatus exists is, whole height is higher, and the operating mechanism position of isolating switch DS and earthed switch ES and FES is also higher, is unfavorable for manual operation; And isolating switch DS can only adopt the linear pattern isolating switch.
The utility model content
The purpose of the utility model is: to the problem that above-mentioned prior art exists, propose that a kind of scheme is simplified, highly lower GIS combined electrical apparatus, and cost-saved, be convenient to operation.
In order to reach above purpose, the technical scheme of the utility model is following: a kind of GIS combined electrical apparatus, comprise main bus bar, and it is characterized in that said main bus bar upper end is fixed with isolating switch, said isolating switch both sides are fixed with voltage transformer and lightning arrester respectively; Said isolating switch, main bus bar, voltage transformer and lightning arrester form T shape structure jointly.
The utility model is simply attractive in appearance, and the integral arrangement symmetrical balance greatly reduces whole height, and the operating mechanism position of isolating switch and earthed switch also greatly reduces, and is convenient to manual operation; Need not three-way body, four-way housing, can practice thrift cost greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the prior art structural representation.
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
The GIS combined electrical apparatus basic structure of present embodiment is as shown in Figure 2, comprises the perpendicular type isolating switch DS that is fixed on main bus bar M upper end, and the both sides of isolating switch DS are fixed with voltage transformer VT and lightning arrester LA respectively; Isolating switch DS, main bus bar M, voltage transformer VT, lightning arrester LA form T shape structure jointly.Isolating switch DS is fixed with earthed switch ES.
Also comprise the underframe that supports main bus bar M, voltage transformer VT and lightning arrester LA pass through shore supports respectively on underframe.Also be supported with on-site control LCP on the underframe, isolating switch DS, main bus bar M, voltage transformer VT, lightning arrester LA all are positioned at the same side of on-site control LCP.
Compared with prior art, present embodiment is simply attractive in appearance, and the integral arrangement symmetrical balance greatly reduces whole height, and the operating mechanism position of isolating switch and earthed switch also greatly reduces, and is convenient to manual operation.
In addition, present embodiment need not three-way body, four-way housing, can practice thrift cost greatly; Adopt pillar to replace the support of prior art, practice thrift cost, easy for installation.
Except that the foregoing description, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
