This connect electric system temporarily with phase shifting transformer, simple structure, practicality are strong, reduce the time of scheduled outage in the in -service use, enhancing power supply reliability.
Description
Technical field
The utility model relates to power construction technical field of operation, is specifically related to a kind ofly connect electric system with phase shifting transformer temporarily.
Background technology
Along with urban construction process fast development and power distribution network is newly-built, the increasing of transformation dynamics, people to scheduled overhaul and breakdown repair time, the requirement that even do not have a power failure of few power failure is more and more higher.The section breaker of current each city distribution network overhead line is few, usually needs whole piece line outage when overhead transmission line maintenance or breakdown repair, or the burst operation troubles of cable line, also needs the longer time to survey and seeks fault point and reparation; The all exigent power supply reliability such as emphasis electric unit or occasion in addition.
For adapting to new model development, electric company must grow with each passing hour and improve constantly technical merit and service quality, promote technological progress and equip upgrading, hit the target fast and overhaul and breakdown repair work, effective solution equipment interruption maintenance and the contradiction to user's uninterrupted power supply, promote safe power supply service quality, meet user's multiple demand, realize electrical network sustainable development establish a firm foundation.
Summary of the invention
The purpose of this utility model is to provide a kind of and connects electric system with phase shifting transformer temporarily, by arranging the first quick plug-in joint, the second quick plug-in joint, bypass load-switch and phase shifting transformer, can when former supply line carries out power-off maintenance, temporary power circuit is connected in former power supply circuits by phase shifting transformer, realizes carrying out continued power to user.Should connect electric system with phase shifting transformer, structure is simple, practical, reduces the time of scheduled outage in actual use temporarily, improves power supply reliability.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
Connect an electric system with phase shifting transformer, be characterized in, this connects electric system temporarily and comprises temporarily:
By-pass unit, is connected with former supply line;
Second quick plug-in joint, respectively with described by-pass unit, temporary power connection.
Preferably, described by-pass unit comprises:
First quick plug-in joint, described first quick plug-in joint one end is connected with former supply line;
Bypass load-switch, described bypass load-switch one end is connected with the described first quick plug-in joint other end;
Phase shifting transformer, described phase shifting transformer one end is connected with the described bypass load-switch other end, and this phase shifting transformer other end is connected with one end of described second quick plug-in joint.
Preferably, described first quick plug-in joint, the second quick plug-in joint all adopt quick plug-in T connector.
Preferably, described bypass load-switch adopts vacuum type high voltage load switch.
The utility model compared with prior art has the following advantages:
The utility model is connected with former supply line by arranging by-pass unit, arranges the second quick plug-in joint and temporary power connection; Thus realize when needs overhaul former supply line or repair time, without the need to power-off, can user's continued power be given, reduce due to maintenance or repair the impact that user power utilization is caused.
Accompanying drawing explanation
Fig. 1 is a kind of overall structure schematic diagram temporarily connecing electric system with phase shifting transformer of the utility model.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind ofly connect electric system with phase shifting transformer, this connects electric system temporarily and comprises: by-pass unit 10, second quick plug-in joint 20 temporarily.
Wherein, by-pass unit 10 is connected with former supply line; Second quick plug-in joint 20 respectively with by-pass unit 10, temporary power connection.
As shown in Figure 1, by-pass unit 10 comprises: the first quick plug-in joint 11, bypass load-switch 12 and phase shifting transformer 13.One end of first quick plug-in joint 11 is connected with former supply line, should; First quick plug-in joint 11 other end is connected with bypass load-switch 12 one end.Bypass load-switch 12 other end is connected with one end of phase shifting transformer 13, and this phase shifting transformer 13 other end is connected with one end of the second quick plug-in joint 20.
Wherein, the first quick plug-in joint 11, second quick plug-in joint 20 all adopts quick plug-in T connector.Bypass load-switch 12 adopts vacuum type high voltage load switch.
In the present embodiment, the first quick plug-in joint 11, second quick plug-in joint 20 all adopts model to be ATT-35/630 type cable joint.Phase shifting transformer 13 is S9M--800KVA/35KV type transformer.
A kind ofly disclosed in the utility model connect electric system with phase shifting transformer, specific works principle is as follows temporarily:
When breaking down in certain of cable line or when certain needs to overhaul, first quick plug-in joint 11 of by-pass unit 10 is connected with the former supply line of Awaiting Overhaul or reparation, adopts power supply flexible cable bypass load-switch 12, phase shifting transformer 13 to be sequentially connected in series; By one end of the second quick plug-in joint 20 and temporary power connection, the other end of this two quick plug-ins joint 20 is connected with phase shifting transformer 13 by power supply flexible cable.
By closed bypass load-switch 12, make cable line and temporary power connection, by regulating phase shifting transformer 13, the power supply characteristic that the power supply characteristic of temporary power line powering and user can be used matches, and then realize the fault place of cable line or Awaiting Overhaul and be in when carrying out power-off reparation or maintenance, realize the continued power to user.
What provide by using the utility model connects electric system with phase shifting transformer temporarily, when can guarantee that Awaiting Overhaul place or fault place carry out overhaul plan, the continued power to user can not be affected, can effectively reduce the scheduled outage time, power supply reliability is provided.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection range of the present utility model should be limited to the appended claims.
