Description
Technical field
The present invention relates to technical field of power systems, and in particular to a kind of power plant direct-current cabinet goes out line detecting method.
Background technology
Power plant direct-current cabinet is in work progress, often because the maloperation of workmen, causes circuit label wrong
By mistake etc., this safe operation to power plant causes great hidden danger, while the electric power data information of power plant direct-current cabinet is past
Past is that the acquisition of analysis personnel analysis user side information also becomes most important, but because these construction errors so that data
Analysis personnel can not obtain correct data message, influence the development of power system.
Existing power plant direct-current cabinet, which goes out line detecting method, includes staff by opening the shutter of direct-current cabinet,
Investigate along the line, determine whether circuit label is correct, but this method efficiency is low, and can not be observed directly running into concealed wire etc.
In the case of line alignment, accuracy rate is low, while also easily direct-current cabinet is caused to damage.Another method is straight by contrasting
Line power data measured by stream screen cabinet busbar and load both ends, so as to judge correct line sequence, but work as and run into multiple lines
Situation about using that road is zero load, then can not determine all line sequences, it would be highly desirable to improve.
The content of the invention
It is reasonable in design, make in view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple in construction
Go out line detecting method with convenient power plant direct-current cabinet, increase power plant staff is detected in direct-current cabinet outlet in work
Flexibility, make up the deficiency that generation current factory direct-current cabinet goes out line detecting method, mitigate power plant direct-current cabinet outlet detection
Cost, practicality are stronger.
To achieve the above object, the technical solution adopted by the present invention is:
Its measurement detecting step is as follows:
First, each circuit running status in power plant direct-current cabinet transmission line of electricity is detected, records testing result;
2nd, according to the testing result of record, all zero load circuits used are extracted;
3rd, described circuit is numbered, and voltage check device is installed successively in load end;
4th, by the breaker of non-loaded circuit at break-make screen cabinet busbar, number measured by voltage check device before and after break-make is collected
According to change, so as to search out corresponding circuit, the record for line sequence of going forward side by side.
Further, the condition monitoring in the step 1, including to each in power plant direct-current cabinet circuit
Circuit is detected, the result based on operational inspection, to reflecting that each state figureofmerit of circuit health status is analyzed and evaluated,
So that it is determined that line status.
Further, described quantity of state is the total of the parameters such as the various technical indicators and running situation for reflecting line conditions
Claim, state-detection is carried out according to each circuit, there can be comprehensive analysis to the transmission line status in hair direct-current cabinet and grasp.
Further, described transmission line status has two, is divided into:Normal condition, abnormal condition;Wherein, normally
Each quantity of state of state representation circuit is in stabilization and within numerical value as defined in code, can be with normal operation;Abnormal condition table
The existence amount change of timberline road does not meet standard limited value, is entering row line survey after should being overhauled.
After said structure, the present invention has the beneficial effect that:A kind of power plant direct-current cabinet outlet inspection of the present invention
Survey method, flexibility of the increase power plant staff in direct-current cabinet outlet detects work, makes up generation current factory direct current
Screen cabinet goes out the deficiency of line detecting method, mitigates power plant direct-current cabinet outlet testing cost, and practicality is stronger, and the present invention has knot
Structure is simple, and it is reasonable to set, the advantages that low manufacture cost.
