Description
Technical field
The present invention relates to field of computer technology, particularly relate to a kind of electric power meter fault on-line checking method and do simulated exercises and checking system.
Background technology
At present, in same device, the electric energy metrical failure simulation device of all manufacturer production, all to promote the metering outfits such as real electric energy meter by light current and forceful electric power, software and hardware normally to run, and certain precision will be reached, otherwise can erroneous judgement be caused, and there is larger gap with the true scene of measuring in this analogue means.This analogue means volume is very big, production cost and transportation cost high, operational process is dangerous, and power consumption is large; The cost of required measurement instrument instrument is corresponding also higher.
At present, all same devices all instruct and self-help training function without tutor.
On-the-spot at the on-line checking method of electric power meter mis-wired, staff is often at a loss what to do to the complicated wiring of electric energy measuring equipment and is at a loss, and the inspection particularly for non-through type electric energy meter mis-wired is had no way of doing it especially.
Electric energy metrical personnel are carrying out in relevant examination or technical ability tourney, and some do not know and first measure electric current or first measuring voltage; Some do not know how to determine middle phase or center line; Also have some can not be determined the actual access way of electric energy meter current by the measurement of phase differential.
Some technician, often do a step and see a step, and measurement limit, limit is groped, and shoots at random.A lot of books introduction be first by the determination of electric current, and then determine voltage.This method is quite complicated and too much consuming time, and thinking analysis amount is too large, and key to find the actual conditions of mis-wired in a lot of situation.
Moreover on-the-spot a lot of technician often relies on so-called intelligent inspection apparatus or equipment.This way is carrying out expressly forbidding in relevant examination or technical ability tourney, and not only the wiring of instrument and equipment itself is quite complicated, and some false wirings only rely on these instrument and equipments be do not go out conclusion, make erroneous judgement even sometimes.
A lot of field personnel's time of can not taking out learns this core skills specially, and time cost and the cost of participating in training are too high; A lot of training on electric power center is not because have the training method of science, and allow trainee control oneself exercise, oneself is groped, and result of training is had a greatly reduced quality.
At present, all same devices are all without random proposition and objective fair evaluation system.In verification of professional technical ability assessment work, examination person often follows one's bent and sets a question, and indiscriminately ad. as one wishes marks to the judged result of examinee, is difficult to ensure the fair and just of qualification examination.
Therefore, when electric power meter is charged, how correctly to determine the actual conditions of fault and mis-wired fast, and then determine the correct electricity that electric power meter measures, become power marketing personnel, comprise the most important core skills of the indispensability of on-the-spot line technology skill such as school personnel repaiied by electric energy meter, dress table meets electric personnel, power utility check personnel, recording, checking, and charging personnel.How objective and fair passes judgment on the technical skills hierarchical level of examinee, is that verification of professional technical ability worker faces problem anxious to be resolved.
