Description
Technical field
This utility model relates to a kind of differential protection, the specifically differential protection of a kind of transformer station, belongs to power equipment applied technical field.
Background technology
Transformer station connects the hinge link between power plant and users, there is the effects such as distribution and converting electric power, to guarantee safety in Operation of Electric Systems process, stability, economical and reliability, in the last few years, the focal point of association area is become about the research of Substation Design aspect.Becoming, in the running of power distribution station power system, due to reasons such as ageing equipment, insulation reduction, maloperations, it is possible to all kinds of fault and abnormal situation occur.When a failure occurs it, very big short circuit current or electric arc can be produced at fault place, burn force device；Abnormal conditions has overvoltage, overcurrent, power system oscillation etc., and these situations can make electrical equipment generate heat, and makes the aging acceleration of insulant, service life reduction.In order to prevent the generation of power failure and abnormal conditions, the safe operation of protection power equipment and power system, differential protection, as a kind of most basic protection device, is widely used, and the safe operation of transformer station is played vital effect by it.But the differential protection that uses of current transformer substation to there is integrated level relatively low, volume is very much not easily installed use, and capacity of resisting disturbance is not enough; communication mode is single; security reliability waits deficiency not, therefore, proposes the differential protection of a kind of transformer station for the problems referred to above.
Utility model content
Have problems for above-mentioned prior art; this utility model provides the differential protection of a kind of transformer station; it is little, lightweight that it has integrated level height, volume; big screen LCD; easy to operate, show the features such as attractive in appearance; the various protection requirements of all kinds transformer and distribution power station can be met, solve Problems existing in background technology.
For achieving the above object, the technical solution adopted in the utility model is: the differential protection of a kind of transformer station, and including shell and the panel being arranged on described shell side, described panel top arranges parameter display screen；Described parameter display screen side arranges Menu key, and described Menu key side arranges selection key；Described selection key is provided above display lamp, and described display lamp side arranges serial line interface；Described serial line interface side arranges USB interface, and described USB interface side arranges fixing plate；Described fixing plate surface configuration fixing hole.
Further, described serial line interface is installed in parallel on described panel, and is electrically connected with selecting key.
Further, described USB interface adopts Universal USB 2.0 interface.
Further, described fixing plate is provided with several holes, equally distributed described location.
Further, described Menu key mutually staggers and arranges and for the identical circle of shape size.
The beneficial effects of the utility model are: integrated level is high, volume is little, lightweight, big screen LCD, easy to operate, show the features such as attractive in appearance, the various protection requirements of the various equipment of all kinds transformer and distribution power station can be met, indoor design adopts special isolation and interference protection measure, capacity of resisting disturbance is strong, and built-in abundant software function, except completing various measurement and protection task, various computer management system can also be connected, complete various measurement and defencive function, high speed failure logging fault dynamically recording, the functions such as frequency analysis and small current earthing wire-selecting.

In figure: 1, shell, 2, panel, 3, display lamp, 4, fixing plate, 5, serial line interface, 6, USB interface, 7, hole, location, 8, select key, 9, parameter display screen, 10, Menu key.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1-2; a kind of differential protection of transformer station, including shell 1 and the panel 2 being arranged on described shell 1 side, described panel 2 top arranges parameter display screen 9; Menu key 10 is set bottom described parameter display screen 9, and described Menu key 10 side arranges selection key 8；Described selection key 8 side arranges display lamp 3, and described display lamp 3 side arranges serial line interface 5；Described serial line interface 5 side arranges USB interface 6, and described USB interface 6 side arranges fixing plate 4；Hole 7, described fixing plate 4 surface configuration location.
As optimisation technique scheme of the present utility model: described serial line interface 5 is installed in parallel on described panel 2, and by being electrically connected with selecting key 8 inside；Described USB interface 6 adopts Universal USB 2.0 interface；Described fixing plate 4 is provided with several holes, equally distributed described location 7；Described Menu key 10 mutually staggers and arranges and for the identical circle of shape size.
This utility model in use, when the electric current of inflow transformer is equal with outflow electric current, be failure to actuate by differential protection.When unequal, display lamp 3 is bright, according to the preliminary failure judgement reason of display lamp 3 light on and off and parameters.Then pass through serial line interface 5 to connect computer and carry out fault analysis and handling, by the program gatherer that writes, can be noted during use using under rated voltage, be fixed in ventilated environment, it is to avoid over-heat inside by USB interface 6.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent replacement and improvement above example made according to technical spirit of the present utility model, should be included within the protection domain of technical solutions of the utility model.
