Abstract
The utility model discloses a low mutual reserve switching device in district of presenting a theatrical performance as last item on a programme, it is including platform district A he tai district B, platform district A he tai district B is respectively through transformer A and transformer B and 10KV line connection, its main points are transformer A and transformer B's back is equipped with the switch switch respectively, low tension switchgear interconnect is passed through to the back of switch, the both ends of low tension switchgear are equipped with the normally closed switch, be connected with measurement ammeter and marketing terminal on the low tension switchgear. The utility model discloses connect the end in adjacent two platforms districts through the low tension switchgear to another district's power supply can be followed to the switch switch that the installation corresponds after the outage appears in a platform district, effectual solved prior art exist circuit power -off time long, seriously influence the technical problem that the user used.
Description
technical fieldthe utility model belongs to electric power conveying technology field, relates to the mutual switching device for subsequent use in a kind of low-voltage platform area.
background technologyalong with growth in the living standard, no matter from production and life, people are more and more strong to the dependence of electricity, also correspondingly the q&r of power supply is had higher requirement, but due to the reason of 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, common to burn out because have zero gram, breaking, ground connection and even distribution transforming burn out, and may be single household or whole district, power failure duration during rush repair is also from 30 minutes to 7/8 hour, and even several days, add that distribution is multi-point and wide-ranging, big and small fault happens occasionally, the power failure of sole user is short for settling time, influence surface is narrow, but relates to whole district's power failure, and power failure amount reaches one hundred houses meter, interruption duration is long, has a strong impact on user and uses.
summary of the inventionthe purpose of this utility model solves prior art to there is the technical problem that circuit power-off time is long, have a strong impact on user's use, provides a kind of low-voltage platform area mutual switching device for subsequent use, to overcome the deficiencies in the prior art.
To achieve these goals, the mutual switching device for subsequent use in a kind of low-voltage platform area of the utility model, it comprises platform district A and platform district B; Described district A and platform district B is respectively by transformer A and transformer B and 10KV connection; Its main points be described transformer A and transformer B be below respectively equipped with chopper switch; The low tension switch that passes behind of described chopper switch is interconnected; The two ends of described low tension switch are provided with normally closed switch; Described low tension switch is connected with metering ammeter and marketing terminal.
The mutual switching device for subsequent use in the utility model low-voltage platform area, the end in adjacent Liang Getai district is connected by low tension switch, and corresponding chopper switch is installed, can power from another district after power-off appears in a Ge Tai district, effectively solve prior art and there is the technical problem that circuit power-off time is long, have a strong impact on user's use.
accompanying drawing explanationaccompanying drawing is the utility model structural representation.
In figure 1, platform district A2, platform district B3, transformer A4, transformer B5, chopper switch 6, low tension switch 7, normally closed switch 8, metering ammeter 9, marketing terminal.
embodimentwith reference to the accompanying drawings, the mutual switching device for subsequent use in a kind of low-voltage platform area of the utility model, it comprises platform district A1 and platform district B2; Described district A1 and platform district B2 is respectively by transformer A3 and transformer B4 and 10KV connection; Described transformer A and transformer B is respectively equipped with chopper switch 5 below; The low tension switch 6 that passes behind of described chopper switch 5 is interconnected; The two ends of described low tension switch 6 are provided with normally closed switch 7; Described low tension switch is connected with metering ammeter 8 and marketing terminal 9.
This device (is convenient to when low tension switch overhauls and change by a high power capacity low tension switch (making reference selected in strict accordance with adjacent stations district capacity of distribution transform), two cover normally closed switch apportion low tension switch both sides, both sides power supply is disconnected), a set of marketing terminal (completes three distant functions-remote measurement voltage, electric current, phase angle, remote control switch deciliter, remote signalling-the terminal of specifying that the signal such as switch divide-shut brake is sent), and one positive and negative equal can the electric energy meter (providing payment foundation for the district that prevents from getting two or more radio stations at once powers) of metering.Adjacent stations district needs three-phase nuclear phase to meet the demands.
After platform district A has a power failure, cut off the chopper switch of this district A and transformer A, closed low switch, platform district B supplies power to platform district A, and after platform district A overhauls, cutoff low switch, closed chopper switch, service restoration is normal.
The utility model has the following advantages
If 1 one Ge Tai districts have a power failure for some reason, disconnected by chopper switch and transformer, the mutual switching device for subsequent use in low-voltage platform area that emergency start is emergent, load is switched to adjacent stations district temporarily and power, ensure that platform district uninterrupted power supply.
2, low tension switch both sides are provided with normally closed switch, can carry out Measuring error after disconnection to low tension switch.
3, to market terminal, can the state of effective this switch of remote monitoring, and the data of understanding load condition and electric current and voltage etc. in time, for correct decisions provides foundation.
4, metering ammeter, mainly convenient calculate adjacent stations district conveying electricity number, avoid and cause the imponderable problem of line loss because getting two or more radio stations at once district.
