Abstract
The utility model discloses an armoured withdrawable alternating current metal-enclosed switchgear, comprising a cabinet, wherein a vertical middle baffle plate, a horizontal handcart guide rail and a handcart capable of sliding on the handcart guide rail are arranged in the cabinet; the handcart is provided with a voltage transformer; the middle baffle plate is composed of an upper section, a middle section and a lower section, wherein the upper section and the lower section of the middle baffle plate are arranged on the same vertical plane while the middle section of the middle baffle plate is arranged at a position 120-150 mm behind the vertical plane, and the position of the middle section of the middle baffle plate is corresponding to the position of the voltage transformer. According to the switchgear disclosed by the utility model, the voltage transformer with large capacity can be installed on the handcart without changing the depth of the handcart, or increasing the depth and width of the switchgear cabinet, and the requirements on safety and maintenance can be met.
Description
Technical field
The utility model relates to a kind of armored withdraw type ac metal closing switch gear.
Background technology
Since first KYN28-12 armored withdraw type ac metal closing switch gear (hereinafter to be referred as switchgear) came out, switchgear had been used in increasing place.Along with the progress of science and technology, many large-scale electric equipments are constantly weeded out the old and bring forth the new.Along with the continuous development and progress of motherland, supply district is also in continuous expansion.The power load of certain required burden of electric substation is in continuous increase, and this just makes the current class of switchgear constantly rise, and its metering task that will bear also constantly increase the weight of.Therefore for providing voltage transformer (hereinafter to be referred as the PT) capacity of operating voltage, metering also wants corresponding increase.
Fig. 1 is the structural representation of general switchgear in the prior art, and traditional median septum G of this switchgear is for being a monoblock vertical plate, and whole plate body is in the same vertical plane.For the switchgear of this structure of Fig. 1, the PT that capacity is not high can be installed on the PT handcart normally, and tank bracket need not done any change; But when the PT capacity is increased to a certain degree; The overall dimensions of PT have to strengthen, and PT is installed on the PT handcart, and the handcart advance distance will be not enough; The safe distance of PT and traditional median septum G can be not enough; Like this can only adopt fixed installation, but adopt fixed mounting means, can't satisfy the acceptance requirement to safety, maintenance aspect of present power supply administration again.
Summary of the invention
The utility model purpose is: propose a kind of armored withdraw type ac metal closing switch gear; This switchgear can be constant in the handcart degree of depth; Under the situation that the switchgear cabinet is not deepened, do not widened; Big capacity voltage transformer is installed on the handcart, and can satisfies the requirement of safety and maintenance aspect.
The technical scheme of the utility model is: a kind of armored withdraw type ac metal closing switch gear; Comprise cabinet; The handcart that is provided with median septum, handcart guide rail in this cabinet and can on the handcart guide rail, slides; On this handcart voltage transformer is housed, said median septum is made up of for three sections upper, middle and lower, and wherein median septum epimere and median septum hypomere are positioned on the same vertical plane; And the median septum stage casing is positioned at the rear 120mm ~ 150mm place of aforementioned vertical plane, and the position in median septum stage casing is corresponding with the position of voltage transformer.
Said median septum stage casing is fixed on the cabinet by screw.
On the said handcart zinc oxide arrester is installed.
The utility model has the advantages that: the median septum of the utility model switchgear is made up of for three sections upper, middle and lower, wherein moves layout and two sections behind the median septum stage casing not on same vertical plane.So, do not increasing under the situation that cabinet is dark and cabinet is wide, big capacity voltage transformer just can be installed, and has saved many costs, and has satisfied the requirement of safety and maintenance aspect.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to introduce:
Fig. 1 is the structural representation of armored withdraw type ac metal closing switch gear in the conventional art;
Fig. 2 is the structural representation of handcart when being in the service position, the utility model switchgear;
Fig. 3 is that handcart is in when testing the position, the structural representation of the utility model switchgear;
Wherein: G is traditional median septum, and 1 is cabinet, and 2 is median septum, and 3 is the handcart guide rail, and 4 is handcart, and 5 is voltage transformer, and 6 is zinc oxide arrester 6, and 2-1 is the median septum epimere, and 2-2 is the median septum stage casing, and 2-3 is the median septum hypomere.
Embodiment
Like Fig. 2, shown in Figure 3, present embodiment armored withdraw type ac metal closing switch gear comprises cabinet 1, is provided with median septum 2, handcart guide rail 3 and handcart 4 in this cabinet 1.Wherein, median septum 2 is vertically arranged, handcart guide rail 3 horizontal arrangement, and handcart 4 can slide front and back on the handcart guide rail, and voltage transformer 5 also is installed on the handcart 4.
The difference maximum with conventional switch equipment is: the median septum 2 in this example is made up of for three sections upper, middle and lower: i.e. median septum epimere 2-1, median septum stage casing 2-2 and median septum hypomere 2-3.Wherein, Median septum epimere 2-1 and median septum hypomere 2-3 are positioned on the same vertical plane; And median septum stage casing 2-1 is positioned at the rear 120mm ~ 150mm place (concrete numerical value decide by the capacity of voltage transformer) of aforementioned vertical plane and passes through screw and is connected with cabinet 1; That is to say median septum stage casing 2-2 with respect to median septum epimere 2-1 and median septum hypomere 2-3 backward translation 120mm ~ 150mm, the three is " isosceles triangle of toppling over " and arranges.And the position of median septum stage casing 2-2 is corresponding with the position of voltage transformer 5---be voltage transformer 5 faces median septum stage casing 2-2; Thereby guarantee that handcart 4 inwardly advances when being in the service position, voltage transformer 5 is not less than safe distance with the spacing of median septum stage casing 2-2.After handcart 4 increased, can also on handcart, also install zinc oxide arrester 6 additional.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection range of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection range of the utility model.
