Description
Affiliated technical field
The present invention relates to a kind of through-flow method of sampling, the specifically through-flow method of sampling of a kind of check protection device, is mainly used in the through-flow sampling test of relay-protection tester substation equipment maintenance and repair protective relaying device multichannel.
Background technology
Through-flow sampling is the verifying work whether check protection device can correctly adopt required current value, be that relay protection and secondary device can safe and stable operations basis.Because existing relay-protection tester all only has A, B, tri-electric current delivery outlets of C, what traditional sampling method can only Yi Lu mono-tunnel does through-flow sampling.If Zuo10 road three-phase through-flow sampling experimental, needs through-flow, the people's thread-changing of a people, people's finder sampled result, at least need 3 people just can complete; Also may need to move tester midway, test period is longer.Plug is not only larger to the damage ratio of terminal so frequently, and waste on life period and manpower, and work efficiency is lower.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the through-flow method of sampling of a kind of check protection device.
The present invention realizes with following technical scheme: the through-flow method of sampling of a kind of check protection device, comprises instrument and the through-flow method of sampling of use;
The instrument using is: relay-protection tester and expansion mouthful; expand mouth and comprise current input terminal and current output terminal; respectively ac current source is divided into multichannel at A, B, C three-phase current input end; on each divided circuit, connect a toggle switch; respectively be provided with a test socket at the corresponding each divided circuit of A, B, C three-phase current output terminal, each toggle switch and and its corresponding test socket between connect respectively a divided circuit resistance.The ratio of described No. 10 divided circuit resistance is: 1: 2: 3: 4: 5: 6: 7: 8: 9: 10; The ratio of divided circuit electric current is: 1: 1/2: 1/3: 1/4: 1/5: 1/6: 1/7: 1/8: 1/9: 1/10;
The through-flow method of sampling is:
One) determine reaying protection test object, choose on demand alternating current way to be measured, pass into current value and calculate the total current value that need to pass into according to the every road of ratio-dependent of each road electric current;
Two) carry out after site safety measure, relay-protection tester is connected with expansion mouthful, device passage to be measured is connected with the output port of expansion mouth, forms closed-loop path, prepares to start test;
Three) utilize relay-protection tester to pass into good total current, be divided into different Multi-path electricities by expansion mouthful and flow in protective device;
Four) sampled data of observing protector, experiment finishes.
The invention has the beneficial effects as follows: it is loaded down with trivial details to have solved the through-flow sampling of substation equipment maintenance and repair relay protection multichannel test, the difficult problem that the cycle is long.Time saving and energy saving, efficiently and accurately reliably completes the through-flow sampling test of multichannel (can simultaneously export at most the different definite value alternating current in 30 tunnels), has avoided again the infringement of plug test wire to terminal row frequently, greatly improves test efficiency.
