Abstract

The utility model relates to a GIS composite electrical apparatus and especially a 110kV high-voltage sulfur hexafluoride GIS composite electrical apparatus containing a lightning arrester and belongs to the technical field of electric power supply equipment. The GIS composite electrical apparatus comprises a main bus supported by an underframe. The main bus is fixedly connected with a breaker successively through a first disconnecting switch (DS1) and a first current transformer (CT1). The breaker is fixedly connected with a second disconnecting switch (DS2) through a second current transformer (CT2). The second disconnecting switch (DS2) is fixedly connected with a cable terminal. The top of the cable terminal is fixedly connected with an inverted lightning arrester. The GIS composite electrical apparatus fully utilizes vertical space so that integral occupied area is substantially reduced. As a result, land utilization efficiency is increased and land using cost is substantially reduced.

Description

A kind of GIS combined electrical apparatus
Technical field
The utility model relates to a kind of GIS combined electrical apparatus, and especially a kind of 110kV high pressure sulfur hexafluoride GIS combined electrical apparatus be used to containing lightning arrester belongs to the power supply equipment technical field.
Background technology
Under the external environment that GIS combined electrical apparatus manufacturer sharply increases, how by reduction procedure, save into the primary work that original increase competitiveness has become current each producer.As shown in Figure 1, existing containing in the 110kV GIS combined electrical apparatus of lightning arrester, main bus bar M top is connected with linear pattern isolating switch DS2 through perpendicular type isolating switch DS1, Current Transmit 1, circuit breaker CB, Current Transmit 2 successively, isolating switch DS2 is connected with a side of three-way body, three-way body is connected with cable termination CSE away from the opposite side of isolating switch DS2, and the three-way body bottom is connected with lightning arrester LA; Circuit breaker CB, lightning arrester LA, cable termination CSE respectively by stent support on underframe; More than all parts all be positioned at the same side of on-site control LCP, and consist of GIS into and out of line branch interval.The problem that this GIS combined electrical apparatus exists is, whole floor space is larger, does not take full advantage of vertical space, and the land used cost is higher.
The utility model content
The purpose of this utility model is: for the problem that above-mentioned prior art exists, propose a kind of GIS combined electrical apparatus that can take full advantage of vertical space, reduce whole floor space, be conducive to reduce the land used cost.
In order to reach above purpose, the technical solution of the utility model is as follows: a kind of GIS combined electrical apparatus, comprise the main bus bar that is supported on the underframe, described main bus bar is connected with circuit breaker through the first isolating switch (DS1), the first current transformer (CT1) successively, and described circuit breaker is connected through the second current transformer (CT2) and the second isolating switch (DS2); It is characterized in that described the second isolating switch (DS2) is connected with cable termination, described cable termination top is fixed with inverted lightning arrester.
The utility model takes full advantage of vertical space, and whole floor space greatly reduces, thereby raising the land utilization efficiency reduces the land used 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 as shown in Figure 2, comprise the main bus bar M that is supported on the underframe, main bus bar M top is fixed with perpendicular type the first isolating switch DS1, and first Current Transmit 1 of the first isolating switch DS1 through laterally placing is connected with the circuit breaker CB bottom of vertical placement; Second Current Transmit 2 of circuit breaker CB top through laterally placing is connected with the side of linear pattern the second isolating switch DS2, and the second isolating switch DS2 is connected away from opposite side and the cable termination CSE of the second Current Transmit 2; Cable termination CSE top is fixed with inverted lightning arrester LA.
The first isolating switch DS1 top is fixed with the first earthed switch ES1; The second isolating switch DS2 bottom is fixed with the second earthed switch ES2 and fail close splice grafting ground switch FES.
Circuit breaker CB, cable termination CSE respectively by stent support on underframe; Isolating switch DS2 by shore supports on underframe.
Also be supported with on-site control LCP on the underframe.Circuit breaker CB, the first and second Current Transmits 1 and CT2, main bus bar M, the first and second isolating switch DS1 and DS2, cable termination CSE, lightning arrester LA all are positioned at the same side of on-site control LCP.
Compared with prior art, present embodiment takes full advantage of vertical space, and whole floor space greatly reduces, thereby raising the land utilization efficiency reduces the land used cost greatly.In addition, present embodiment need not three-way body, also can save a support, can reduce cost.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all fall into the protection range of the utility model requirement.
