Abstract

ThisInventionDisclose one kindLow-voltage platform area low-voltage power supply standby power throw-in device, it includes platform area A and platform area B;Described area A and platform area B pass through transformator A and transformator B and 10KV connection respectively;Its main points is to be respectively equipped with chopper switch behind the transformator A and transformator B;The low tension switch that passes behind of the chopper switch is connected with each other;The two ends of the low tension switch are provided with normally closed switch;Metering ammeter and marketer terminal are connected with the low tension switch.ThisInventionThe end in two neighboring area is attached by low tension switch, and corresponding chopper switch is installed, can power from another area after power-off occur in a Ge Tai areas, effectively solve prior art and there is circuit power-off time length, have a strong impact on the technical problem that user uses.

Description

Low-voltage platform area low-voltage power supply standby power throw-in device
Technical fieldThisInventionBelong to power transmission technical field, be related to one kindLow-voltage platform area low-voltage power supply standby power throw-in device
Background technologyWith growth in the living standard, no matter from production and life, dependence of the people to electricity is more and more strong, also the q&r correspondingly to powering is put forward higher requirement, but due to due to left over by history, the present situation of Distributing network structure and annual distribution investment, the expectation of people in the short time, cannot be met.
Often there is power-off in distribution Jing, common factor has zero gram burn out, break, ground connection or even distribution transforming burn out, it may be possible to single household or whole platform area, power failure duration during the rush repair also hour from 30 minutes to 7/8, or even several days, adding that distribution is multi-point and wide-ranging, big and small failure happens occasionally, it is short that the power failure of sole user solves the time, impact face is narrow, but is related to whole platform area power failure, power failure amount up to one hundred houses meter, power off time is long, has a strong impact on user's use.
The content of the inventionThisInventionPurpose be to solve prior art to there is circuit power-off time length, have a strong impact on the technical problem that user uses, there is provided it is a kind ofLow-voltage platform area low-voltage power supply standby power throw-in device, to overcome the deficiencies in the prior art.
To achieve these goals, originallyInventionIt is a kind ofLow-voltage platform area low-voltage power supply standby power throw-in device, it includes platform area A and platform area B;Described area A and platform area B pass through transformator A and transformator B and 10KV connection respectively;Its main points is to be respectively equipped with chopper switch behind the transformator A and transformator B;The low tension switch that passes behind of the chopper switch is connected with each other;The two ends of the low tension switch are provided with normally closed switch;Metering ammeter and marketer terminal are connected with the low tension switch.
ThisInvention Low-voltage platform area Low-voltage power supply standby power throw-in deviceThe end in two neighboring area is attached by low tension switch, and corresponding chopper switch is installed, can power from another area after power-off occur in a Ge Tai areas, effectively solve prior art and there is circuit power-off time length, have a strong impact on the technical problem that user uses.
Accompanying drawing Explanation Accompanying drawingIt is thisInventionStructural representationFigure
In figure1st, platform area A 2, platform area B 3, transformator A 4, transformator B 5, chopper switch 6, low tension switch 7, normally closed switch 8, metering ammeter 9, marketer terminal.
Specific embodimentAccording toAccompanying drawing, thisInventionIt is a kind ofLow-voltage platform area low-voltage power supply standby power throw-in device, it includes platform area A1 and platform area B2;Described area A1 and platform area B2 pass through transformator A3 and transformator B4 and 10KV connection respectively;Chopper switch 5 is respectively equipped with behind the transformator A and transformator B;The low tension switch 6 that passes behind of the chopper switch 5 is connected with each other;The two ends of the low tension switch 6 are provided with normally closed switch 7;Metering electricity is connected with the low tension switchTable 8With marketer terminal 9.
This device is by a high power capacity low tension switch(Make reference in strict accordance with adjacent stations area capacity of distribution transform selected), two sets of normally closed switch point row low tension switch both sides(It is easy to, when low tension switch is overhauled and is changed, both sides power supply be disconnected), a set of marketer terminal(Complete three distant functions-remote measurement voltage, electric current, phase angle, remote switch division, remote signalling-the terminal specified that the signals such as switch divide-shut brake are sent), and a positive and negative equal electric energy that can be measuredTable(Power offer payment foundation for the area that prevents from getting two or more radio stations at once).Adjacent stations area needs three-phase nuclear phase to meet requirement.
After platform area A has a power failure, the chopper switch of area A and transformator A is cut off, closed low switch, platform area B supply power to platform area A, after A maintenance in platform area is finished, cutoff low switch closes chopper switch, and service restoration is normal.
ThisInventionWith advantages below
If the 1, a Ge Tai areas have a power failure for some reason, disconnected with transformator by chopper switch, what emergency start was met an urgent needLow-voltage platform area low-voltage power supply standby power throw-in device, load is switched to into adjacent stations area temporarily and is powered, it is ensured that platform area uninterrupted power supply.
2nd, low tension switch both sides are provided with normally closed switch, can carry out Measuring error to low tension switch after disconnection.
3rd, marketer terminal, can effectively remote monitoring this switch state, and in time understand load condition and voltage x current etc. data, provide foundation for correct decisionss.
4th, metering ammeter, mainly facilitate calculate adjacent stations areas conveying electricity number, it is to avoid cause the imponderable problem of line loss because getting two or more radio stations at once area.
