Description
Technical field
The utility model relates to trouble-shooter, particularly the diagnosing looped network cabinet failure device.
Background technology
Shanghai Power Network is the super-huge city electrical network in the fast development.World Expo will be held in 2010 in Shanghai, will become one of international economy, finance, trade, shipping centre to the year two thousand twenty Shanghai, and the socio-economic status in Shanghai has determined electrical network to be one reliability and the quality of power supply required high electrical network.In the Shanghai Urban electrical network, the 10KV ring main unit that gos deep into community is the important step of user's power distribution network power supply quality and power supply reliability.Shanghai City 10KV ring main unit majority is not realized remote monitoring at present, obtains if the ruuning situation of grasp circuit and equipment needs the pipeline rider regularly to ask inspection.Because 10KV ring main unit enormous amount, this way by artificial understanding equipment and circuit ruuning situation, in workload still is very big defective all to be arranged aspect the fault judgement real-time, target for " building the digitizing electric power system; realize power system monitor digitizing, service handling informationization and enterprise operation intensification " in the realization Shanghai Power Company Eleventh Five-Year Plan program for the development of science and technology realizes that the ring main unit remote real time monitoring is significant and urgency simultaneously.But Shanghai 10KV ring main unit majority does not have low pressure 220V power supply, and because ring main unit is of a great variety, factors such as erecting stage complexity are all given the 10KV ring main unit monitored and brought difficulty.In order to address the above problem, the diagnosing looped network cabinet failure device that the plan development of for a long time grand Power Tech Corp. Inc. has the telecommunication means, this device can be accomplished to make Current Transformer as power supply, super capacitor is as back-up source, the place of the running status of detection line and fault generation in real time is such as sending electricity, power failure, ground connection, short circuit, overcurrent etc.When changing, the circuit running status is uploaded to the dispatching terminal server rapidly by cable shield carrier communication means, failure judgement may origination point automatically by the software specialist system for server, inform monitor staff and managerial personnel, handle it fast, can greatly improve power supply reliability, improve user's satisfaction.Realized that circuit and equipment operation carry out real time implementation, information system management.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of high-efficiency reliable diagnosing looped network cabinet failure device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the diagnosing looped network cabinet failure device, it is characterized in that, comprise that power supply, back-up source, communication module, server, described power supply, back-up source connect respectively at communication module, described communication module is connected with the server communication.
Described power supply is a current transformer.
Described back-up source is a super power supply.
Compared with prior art, the utlity model has following advantage:
1, realizes that the ring main unit failure message is long-range, initiatively reports, determine fault section, branch and trouble spot rapidly.The backward way that thoroughly changes past timing line walking or do not monitor is increased work efficiency greatly, shortens power off time, improves power supply reliability and economic benefit effectively;
2, in time understand the ring main unit duty, provide foundation the line work state analysis;
3, preserve the current conditions of fault origination point front and back, provide foundation for carrying out fault analysis;
4, be accumulated under the no 220V low tension work environment, by the current transformer power taking, the on-the-spot practical experience of the power supply of super capacitor reserve electric power storage.
Description of drawings
Fig. 1 is the structural representation of the utility model diagnosing looped network cabinet failure device.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, diagnosing looped network cabinet failure device of the present utility model, it is characterized in that comprise that power supply 1, back-up source 2, communication module 3, server 4, described power supply 1, back-up source 2 connect respectively at communication module 3, described communication module 3 is connected with server 4 communications.Described power supply 1 is a current transformer.Described back-up source 2 is a super power supply.
Ring main unit accident indicator profile installation and design requires to meet the inner requirements of installation space of ring main unit, can conveniently install, size do not influence the ring main unit safety line apart from, and consider requirements such as moistureproof, anticorrosion, insulation.
Ring main unit accident indicator supply current mutual inductor profile will meet ring main unit inner cable installation requirement, is easy for installation and removal;
Electric current is less on the ring main unit, needs design specialized supply current mutual inductor, improves the electrorheological ratio, to guarantee the normal power source supply.
Because of ring main unit accident indicator consumed power when the cable shield carrier communication bigger, the supply current mutual inductor can't normally ensure the power supply supply, so need to consider high power capacity, non-maintaining back-up source (super capacitor), the capacity of back-up source should safeguards system sends time of fault-signal to dispatch server, and non-maintaining in 5-10.
It is limited to consider that the supply current mutual inductor produces electric current, needs design high-level efficiency super capacitor back-up source charge function, ensures electric energy storage to greatest extent.
Because of the ring main unit accident indicator should adopt more general interface, can change communication mode, such as mobile module communication (SMS, GPRS or CDMA), data radio station communication, RF communication or the like, to satisfy different on-the-spot communicating requirements.
The timing of adopting because of the ring main unit accident indicator adds the real-time Communication for Power mode, initiatively uploads in real time during fault, non-fault regularly reports working condition.
