Description
Technical field
The utility model relates to a kind of electric device, specifically a kind of backup auto-activating device.
Background technology
Perfect further along with electrical network, the bus connection type of electric substation there occurs larger change, especially at 110kV, in the electric substation of the high voltage grades such as 220kV, double bus scheme form becomes main flow, but the backup auto-activating device on market does not upgrade raising along with the development of electrical network, still the bus structure being applicable to traditional sectionalized single busbar connection or internal bridge connection is rested on, double-bus structure destroy original backup auto-activating device need be fixedly connected with mode, have and more to change more flexibly, so existing backup auto-activating device can not meet the demand of double-bus electric substation on market.The wherein one in the various operational mode of double bus scheme can only be protected, the action that backup auto-activating device traditional when this just causes double-bus to be run can not be correct.
Utility model content
The purpose of this utility model is to provide a kind of backup auto-activating device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of backup auto-activating device, comprise prepared auto restart voltage sample loop and prepared auto restart switching circuitry, busbar voltage corresponding to inlet wire is accessed in described prepared auto restart voltage sample loop on the terminal of the female voltage of backup auto-activating device Central Plains access I, the female voltage of II, and voltage after the switching of corresponding for inlet wire protective device is introduced backup auto-activating device; Described prepared auto restart switching circuitry is opened entry loop at prepared auto restart bus connection switch auxiliary contact and is met a pressing plate LP.
Compared with prior art, the beneficial effects of the utility model are: the utility model backup auto-activating device meets the general principle of prepared auto restart, and access information is simple, and self adaptation is strong, correct response can be made to different dead electricity situations, the reliability that double bus scheme is powered can be improved.Simultaneously under the prerequisite not changing manufacturer's existing product equipment, by improving external wiring pattern, reach the various operational mode and action logic that meet double bus scheme, less demanding to field operator, this device still can meet the operational mode of sectionalized single busbar connection and bridge connection prepared auto restart simultaneously, improves the standardization of backup auto-activating device, the feature that unitized and adaptive ability is strong.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 6, in the utility model embodiment, a kind of backup auto-activating device, comprise prepared auto restart voltage sample loop and prepared auto restart switching circuitry, busbar voltage corresponding to inlet wire is accessed in prepared auto restart voltage sample loop on the terminal of the female voltage of backup auto-activating device Central Plains access I, the female voltage of II, and voltage after the switching of corresponding for inlet wire protective device is introduced backup auto-activating device; Prepared auto restart switching circuitry is opened entry loop at prepared auto restart bus connection switch auxiliary contact and is met a pressing plate LP.
Operation principle of the present utility model is: Fig. 1 ~ 4 are four kinds of operational modes that double bus scheme is conventional.Mode one mode two is inlet wires 1, inlet wire 2 runs on positive mother respectively, on secondary bus, bus connection switch stand-by heat; Mode three, mode four are for supplying full institute load through bus connection switch, another service entrance switch stand-by heat one time in two inlet wires.It is few that tradition backup auto-activating device employs logic, and device, according to the logic operation of setting, is just applicable to the wherein one of four kinds of possibilities in double bus scheme operational mode, i.e. first kind of way or the second way.The mode of connection of double-bus due to operational mode flexible, the voltage of prepared auto restart can not directly introduce fixing busbar voltage, and need the connected mode along with inlet wire and bus and become, simultaneously when two circuits run on same bus, do not need to differentiate just should charge to backup auto-activating device in the position of bus connection switch.Visible traditional prepared auto restart is applicable to there is two problems in double bus scheme mode, one be access into right busbar voltage be not fixing busbar voltage; Two is that mother deciliter situation determines the need of differentiation bus connection switch position.
Prepared auto restart voltage sample loop diagram after Fig. 5 change.The busbar voltage not fixation problem corresponding to inlet wire is accessed for Fig. 1; the terminal of the female voltage of backup auto-activating device Central Plains access I, the female voltage of II accesses busbar voltage corresponding to inlet wire; backup auto-activating device is made to introduce voltage consistent with the physical cabling busbar voltage of inlet wire; only voltage after the switching of corresponding for inlet wire protective device need be introduced backup auto-activating device, this addresses the problem the backup auto-activating device that mode two and mode four produce above can not correct operation problem.
Prepared auto restart switching circuitry figure after Fig. 6 change.All can start for prepared auto restart under Fig. 1 mode one and mode 2 two kinds of modes, but when occurring that the third or the 4th kind of operational mode there will be a problem when that is two articles of circuits run on same bus.Two inlet wires all run on same section of bus, and now bus connection switch is inspecting state, if inlet wire I is main power supply, another inlet wire is stand-by heat.Meet circuit backup power automatic switching condition, but because backup auto-activating device needs to judge that the position of bus connection switch is in co-bit under circuit backup power automatic switching mode, therefore although now primary connection circuit possesses prepared auto restart condition, prepared auto restart still cannot complete recharge logic, and this is irrational, on reach situation, make following amendment, open entry loop at prepared auto restart bus connection switch auxiliary contact and meet a pressing plate LP, simulating the situation of bus connection switch in co-bit, to meet prepared auto restart recharge logic.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
