Abstract
The present invention discloses a failure current protection switch, is set out by this switch of four blade sluice foundation of-63A (the wide 4M of assembly), covers the whole protection ranges of four blade lock design to 125A (the wide 5M of assembly) from the double-pole lock design of 40A (the wide 2M of assembly).All switches all are provided with an arc-control device (9), one group of contact (10) and a Control Shaft (11) for each disconnecting link at the width that is equivalent to an assembly (1M) in the lower cover (1) of its shell, and arrange to have ground connection end plate (12), a total current current transformer (13), a testing apparatus (15) and a contact position indicating device (16) that comprises the releasing device (14) of an assembly wide (1M) in the loam cake (3) of shell.
Description
The present invention relates to failure current protection switch, is to have a shell that is made of upper and lower cover that is used for holding a plurality of switch tools, one and suitable arc-control device, a releasing device, a total current current transformer and the input of switch tool, the failture current protection device of out splice going splice about a kind of specifically.
Failure current protection switch as this class has been known technology (as the open DE-PS 235506 of Deutsche Bundespatent).In this switch, total current current transformer and checkout gear are arranged in the bearing of an activity, also are provided with the moving contact part of sets of contacts in addition.Total current transformer is made to the bearing that has moving contact and gives the system unit, so that can easily be assembled into a plurality of failure current protection switch.But the structure of this movable bearing support only is applicable to the switch solution in the very little field, because be difficult to or may guarantee hardly the shell sizes of switch thus.And all need excessive expense in all cases.
Therefore; task of the present invention designs a kind of failure current protection switch exactly; it can be applicable to that one group comprises from the double-pole failure current protection switch of the 16～40A switch family up to the four blade failure current protection switch of 40～125A; its total protection range when fuse is 100A rated current to 100A, fuse for the 125A rated current to 125A, the switch volume of passenger traffic can reach 10KA.
According to the present invention, this task is that following array structure characteristics combination is finished.Promptly in a failure current protection switch, in switch housing, lower cover inner space and outer casing upper cover are separated by a central dividing plate that parallels setting with the lower cover base plate, at base plate and central dividing plate thus and will import, in the formed space of sidewall that out splice going splice separates, for each switch tool is provided with an arc-control device and one group of contact that is connected to Control Shaft with the width that is equivalent to an assembly; In outer casing upper cover inside total current current transformer and releasing device and a ground connection end plate are contained in simultaneously, and this ground connection end plate and releasing device are placed in the space of an element width jointly; And for the switch of different rated current, can adopt identical parts, as ground connection end plate, releasing device, extinguisher, checkout gear and contact position indicating device etc., be assembled into various switch solution, and all these schemes all has identical cover size (A); Their width (package count) is by the size of total current current transformer and the length decision of Control Shaft, and the switch height then only depends on the size of input, out splice going splice.
Be that by the obtainable advantage of the present invention the various switches in this switch family can be assembled by very consistent parts, and its assembling effect (that is its internal structure) almost can keep identical.
The superiority that further develops of above-mentioned these characteristics can reach by described in the dependent claims.
Provided an embodiment in the accompanying drawing, done below to describe in detail.In the listed accompanying drawing:
Figure 1 shows that the side sectional view of a failure current protection switch;
Figure 2 shows that the complete top view of lower cover part when removing central dividing plate of outfit of this failure current protection switch;
Figure 3 shows that the item view of the failure current protection switch when removing loam cake;
Fig. 4 is to the top view that Figure 9 shows that whole switch family.
Made a graphic extension as the four blade lock failure current protection switch of the basic switch of this switch family among Fig. 1 to Fig. 4.Affiliated switch housing is made up of a lower cover 1 and a loam cake 3 that has base plate 2.The central dividing plate 4 that be arranged in parallel with base plate 2 is divided into two chambers with the enclosure space.At outer casing underpart, constitute a chamber by base plate 2 and central dividing plate 4 and sidewall 5 and 6.Another chamber is formed space between loam cake 3 and central dividing plate 4 then.For giving, input adapter 7 and out splice going splice 8 leave the device space in the enclosure.In the chamber of lower cover 1, be provided with 9, one groups of contacts 10 of an arc-control device and a Control Shaft 11.One ground connection end plate 12 is arranged in the loam cake 3 of shell, and this only can be by seeing among Fig. 3.In loam cake, also be provided with the checkout gear 15 that a total current current transformer 13, one releasing devices 14, are made up of a testing button and test resistance device in addition, and a contact position indicating device 16.
Made the basic switch of this switch family among Fig. 4, i.e. a 63A four blade lock failure current protection switch with 4M element width.The switch solution of one 40A then for as shown in Figure 5 have a wide failure current protection switch of 3M assembly.
Figure 6 shows that the failure current protection switch of the wide 4M of assembly of a 100A scheme, what Figure 7 shows that the 125A scheme has a wide failure current protection switch of 5M assembly.At Fig. 5 to Fig. 7 all is to consider the four blade lock failure current protection switch that adopts respectively.Adopt double-pole lock failure current protection switch to illustrate two schemes.Fig. 8 is the failure current protection switch of a 80A scheme, and its assembly is wide to be 3M, and shown in Figure 9 then is that the element width of a 40A scheme is the failure current protection switch of 2M.
Whole switches of this switch family all will have consistent outer cover size A.
