Abstract
Shell is protected the utility model discloses a kind of novel zero sequence transformer; including protective cover lower casing; the upper end of the protective cover lower casing connects the lower end of protective cover upper casing; ZCT is housed inside the protective cover lower casing; the one side of the protective cover upper shell upper portion screws cap by wire lead-out structure and wire and is attached; the protective cover upper casing is made up of protective cover upper casing inner housing and protective cover upper casing shell body, and the protective cover upper casing inner housing is arranged on the left side of protective cover upper casing shell body.The utility model complex degree of structure is substantially reduced, and is manufactured, using simple, is connected reliable, convenient disassembly, wire fairlead draws wire, and wire draws the use of aperture waterproof coating, makes transformer and external environment, so as to play dust-proof, moistureproof purpose.
Description
Technical field
The utility model belongs to electric security protector engineering device technique field, and in particular to a kind of novel zero sequence transformer protection
Shell.
Background technology
The outgoing line cabinet of existing outdoor ring main unit, typically all breaker cabinet are, it is necessary to install ZCT, to ensure zero sequence
Protection can be operating normally.Simultaneously as the general volume of ZCT is larger, and the volume of the cable vault in outdoor ring main unit
It is smaller, therefore, typically by ZCT as in the cable duct below cable vault in practical operation.Because cable duct typically compares
Moister, and there is dust, therefore, ZCT easily through moisture and dust accretions, produces short-circuit conditions, influence protection
The normal work of device, or even false protection is produced, improper tripping operation is switched, normal power supply is influenceed.Therefore, invention is a kind of new
ZCT protects shell, goes to solve the above problems, very promising.
Utility model content
The purpose of this utility model is to provide a kind of novel zero sequence transformer protection shell, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of novel zero sequence transformer protects shell,
Including protective cover lower casing, the upper end of the protective cover lower casing is connected to be filled inside the lower end of protective cover upper casing, the protective cover lower casing
There is ZCT, the one side of the protective cover upper shell upper portion screws cap by wire lead-out structure and wire and is attached,
The protective cover upper casing is made up of protective cover upper casing inner housing and protective cover upper casing shell body, and the protective cover upper casing inner housing is set
Put on the left side of protective cover upper casing shell body.
It is preferred that, the protective cover lower casing installs housing two parts group by protective cover lower casing shell body and protective cover lower casing
Into provided with internal thread inside the protective cover lower casing shell body.
It is preferred that, the material that the wire screws cap is rigid plastics.
It is preferred that, the wire lead-out structure and wire screw cap and are coaxially arranged with wire fairlead.
Technique effect of the present utility model and advantage：The utility model ZCT protection shell mechanism complexity is big
Big reduction, manufactures, using simple, connects reliable, convenient disassembly, wire fairlead draws wire, and wire draws aperture
The use of waterproof coating, makes transformer and external environment, so as to play dust-proof, moistureproof purpose.The utility model passes through design
It is scientific and reasonable, on the premise of the dimensional parameters of ZCT, appearance forrns are not changed, it can adapt to for most zero sequences
Transformer, and can Fast Installation dismounting, practical, fault rate is few, long lifespan.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model structure schematic top plan view.
In figure：1 protective cover lower casing, 2 ZCTs, 3 protective cover upper casings, 4 wire lead-out structures, 5 wire fairleads, 6
Wire screws cap, 7 protective cover upper casing inner housings, 8 protective cover upper casing shell bodies, 9 protective cover lower casing shell bodies, 10 protective cover lower casings
Housing is installed.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is passed through
Following two parts are described：
As described in Fig. 1-2, a kind of novel zero sequence transformer protects shell, including protective cover lower casing 1, the protective cover lower casing
The lower end of 1 upper end connection protective cover upper casing 3, the inside of protective cover lower casing 1 is equipped with ZCT 2, the protective cover
The one side on the top of shell 3 screws cap 6 by wire lead-out structure 4 and wire and is attached, and the protective cover upper casing 3 is by protective cover
Upper casing inner housing 7 and protective cover upper casing shell body 8 are constituted, and the protective cover upper casing inner housing 7 is arranged on protective cover upper casing shell
The left side of body 8.The protective cover lower casing 1 is installed the two parts of housing 10 by protective cover lower casing shell body 9 and protective cover lower casing and constituted,
The inside of protective cover lower casing shell body 9 is provided with internal thread.The material that the wire screws cap 6 is rigid plastics.The wire
Deriving structure 4 and wire screw cap 6 and are coaxially arranged with wire fairlead 5.
Embodiment：By ZCT 2 as in protective cover lower casing 1, wire is drawn from wire fairlead 5, then will
The upper casing 3 of protective cover lower casing 1 and protective cover is installed；Wire is passed into the wire fairlead 5 that wire screws cap 6 simultaneously, then will
Wire screws cap 6 and screwed with wire fairlead 5.So, ZCT 2 is just placed in inside protective cover completely, so as to play
Dust-proof, moistureproof purpose.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
It should be included within protection domain of the present utility model.
