Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
Air insulation switch does not have breakthrough progress on miniaturization technology at present, and domestic technology is followed in sb's footsteps to the technology of external maturation in this respect.Propose a kind of pole column structure herein, adopted the circuit breaker of this pole column structure and adopted the switch cubicle of this circuit breaker, solve the miniaturization issues of air switch and the device based on this air switch, made air insulation switch in miniaturization, approach the level of supplementary insulation switch.
The technology major part of domestic switch derives from abroad, and the past is the Soviet Union, is American-European recently.In prior art, in switch topology, all adopt two schemes: one is that three-phase pole left, center, right is arranged and every pole is all vertically arranged, is the front view of the pole column structure of this layout as shown in Figure 1a, and Fig. 1 b is its vertical view, and Fig. 1 c is its end view; Another kind be before three-phase pole in after arrange and every pole vertically arrange, be the front view of this pole column structure as shown in Figure 2 a, Fig. 2 b is its vertical view, Fig. 2 c is its end view.Wherein, above-below direction is vertical, and left and right directions is laterally, and is longitudinal perpendicular to the direction of vertical plane.
Due in switchgear house, switch cubicle is in a row to arrange, and therefore the width of switch cubicle is less, and the switch cubicle that onesize switchgear house holds is just more.And in height and the degree of depth, however affect the space of switchgear house, can not affect the quantity that can hold switch cubicle.Therefore, the width of switch cubicle is the key that realizes the miniaturization of switch and the device based on switch, and the width of pole column structure directly affects the width of switch and switch cubicle etc.
When the pole column structure of switch is for arranging and when every pole vertically arranges, the width of switch depends on that conductor is apart from the insulation distance of framework, several factors such as width and alternate insulation distance of conductor three-phase pole left, center, right as shown in Fig. 1 a, Fig. 1 b and Fig. 1 c.Now the width of switch equal 2 times of conductors apart from the width of the insulation distance of framework, 3 times of conductors and 2 times of phase insulations apart from sum.
When the pole column structure of switch for as shown in Fig. 2 a, Fig. 2 b and Fig. 2 c before three-phase pole in after arrange and when every pole vertically arranges, limit by structure, if this pole column structure is for switch cubicle, owing to laterally there being other switch cubicles arranged side by side, switch moves and can only oriented manipulation person move forward and backward, therefore this pole column structure is used for fixing cabinet, and is not suitable for withdraw-type switch.The width of this switch depends on that conductor is apart from the insulation distance of framework and the width of conductor on the one hand, on the other hand, because Primary Conductor will form loop, other electric components can only be arranged on the side of pole, so also depend on that some other components and parts are as the space of installing and using of instrument transformer, earthed switch, cable etc.Therefore on width, the switch most cases of this pole layout is not also preponderated.
Therefore, the width of aforementioned two kinds of pole column structures is all larger, in switch miniaturization, is difficult to make progress.
The problem that is difficult to realize just miniaturization based on traditional switch on width, the utility model proposes a kind of pole column structure, and this pole column structure comprises the three-phase pole that upper, middle and lower is arranged, wherein each phase pole is parallel between two, and is longitudinal layout.Meanwhile, three-phase pole includes input and output, and input and output all stretch to pole front end, and wherein front end refers to the one end away from operator.Meanwhile, the input of each phase pole is by wrapped with insulation, to insulate and to support described pole.In this pole column structure, the internal structure of three-phase pole is identical, and the spacing between two adjacent poles equates.In addition, the input of pole comprises Duckbilled contact, and output comprises contact blades.
Although the pole column structure of this layout height for first two pole column structure can increase, and increases not quite, can not affect the height of its place switchgear house.Meanwhile, based on the location layout of each compartment, adopt the height of the switch cubicle of this pole column structure can not increase.In this external degree of depth, adopt the switch cubicle of this structure also can not increase too much, also do not reach the big or small degree that affects switchgear house far away.
Fig. 3 a is depicted as the front view of this pole column structure, and Fig. 3 b is its vertical view, and Fig. 3 c is its end view, and wherein 1 is A phase pole, and 2 is B phase pole, and 3 is C phase pole.In the time that upper, middle and lower layout and each phase pole itself are longitudinally arranged between three-phase pole, because pole is arranged in vertically in (i.e. height) and longitudinal (being the degree of depth) direction, width is significantly reduced; Simultaneously because each components and parts of this pole column structure are all on the longitudinal direction of pole, little on the impact of its width, further promote reducing of this pole column structure width.Adopt the width of the switch of this pole column structure to depend on that conductor is apart from the insulation distance of framework and the width of conductor, equal the width sum of 2 times of conductors apart from insulation distance and the conductor of framework.
Therefore, the width of this pole column structure is significantly less than the width of three-phase pole left, center, right layout and the vertical pole column structure of arranging of each phase pole.And arrange with after in before three-phase pole and the vertical pole column structure of arranging of each phase pole compared with time, due in rear a kind of pole column structure, its primary circuit input and output, in side, have increased its width; And in this pole column structure, the input of primary circuit and output are all in the direction of its degree of depth at the longitudinal direction of pole, impact on width is very little, therefore its width be also less than under same case before three-phase pole in after arrange and the width of the vertical pole column structure of arranging of each phase pole.Thereby, adopt the width that is less than the switch of pole column structure in employing prior art as the width of the air switch of pole column structure described in the utility model, make the switchgear house of same width, the switch cubicle holding can double even more.
