Abstract

The invention relates to a method for RMU (ring main unit) fault diagnosis. The method comprises the following steps: when the operation state of a line changes, the change is rapidly uploaded to a dispatching terminal server by a carrier communication means of a cable shielding layer; the server can automatically judges the possible points of a fault by the treatment; the server notices monitoring staff and management staff to rapidly make a disposition decision; and the real-time and information management of the line and equipment is carried out. Compared with the prior art, the method has the following advantages: the method realizes the remote and active report of fault information of an RMU, and rapidly determines fault sections, branches and fault points; the laggard practice of regular line patrol or no monitoring in the past is completely changed, the working efficiency is greatly improved, the power failure time is shortened, and the reliability and the economic benefits of power supply are effectively improved; the working state of the RMU is known timely, thereby providing the basis for analyzing the working state of the line; and the current situations before and after the fault points are saved, thereby providing the basis for analyzing the faults.

Description

A kind of method of diagnosing looped network cabinet failure
Technical field
The present invention relates to method for diagnosing faults, particularly a kind of method of diagnosing looped network cabinet failure.
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 line attendant 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 digitlization electric power system; realize power system monitor digitlization, 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 bed 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 administrative staff, 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
Purpose of the present invention is exactly the method that a kind of high-efficiency reliable diagnosing looped network cabinet failure is provided for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of method of diagnosing looped network cabinet failure is characterized in that this method may further comprise the steps:
(1) when changing, the circuit running status is uploaded to the dispatching terminal server rapidly by cable shield carrier communication means;
(2) server is by handling failure judgement possibility origination point automatically;
(3) server is informed monitor staff and administrative staff, handles it fast;
(4) realize that circuit and equipment operation carry out real time implementation, information system management.
Compared with prior art, the present invention has the following advantages:
1, realizes that the ring main unit fault message is long-range, initiatively reports, determine fault section, branch and fault point rapidly.The backward way that thoroughly changes past timing line walking or do not monitor is increased work efficiency greatly, shortens interruption duration, improves power supply reliability and economic benefit effectively;
2, in time understand the ring main unit operating state, provide foundation the line work state analysis;
3, preserve the current conditions of fault origination point front and back, provide foundation for carrying out accident 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.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
A kind of method of diagnosing looped network cabinet failure, 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 administrative staff, handle it fast, can greatly improve power supply reliability, improve user's satisfaction.To realize that circuit and equipment operation carry out real time implementation, information system management.
