Abstract
The invention discloses a trip by local protection export loop test method which comprises the following steps of: 1. putting into a trip pressing plate of any one trip export loop to start up a protection device, and at this moment, measuring the trip export loop to be switched on by a universal meter; 2. exiting the trip pressing plate of the trip export loop and putting into all other trip pressing plates to start up the protection device again, and measuring the trip export loop by the universal meter to respectively judge whether a trip junction of the trip export loop exports via the trip pressing plates of other trip export loops and whether parasitical loops export among trip loops according to two conditions that the trip export loop is switched on and off; in the step 2, if the universal meter measures that the trip export loop is switched off, judging that the trip junction of the trip export loop does not export via the trip pressing plates of other trip export loops and no parasitical loops export among trip loops, thus, judging that the test result is qualified.
Description
Technical field
The present invention relates to a kind of protective relaying device tripping operation outlet loop test method.
Background technology
The tripping operation contact of the protective relaying device back of connect with the tripping operation pressing plate constitutes the tripping operation outlet loop, and a tripping operation contact can only be connected with a tripping operation pressing plate, and other trip and between outlet loops parasitic loop must not be arranged.Should check the correctness of tripping operation outlet loop in the debugging; common inspection method is: the first step; drop into the tripping operation pressing plate of a certain tripping operation outlet loop; allow protective device move, measure this tripping operation outlet loop for logical with multimeter this moment, second step; withdraw from the tripping operation pressing plate of this tripping operation outlet loop; allow protective device move once more, measure this tripping operation outlet loop with multimeter this moment is obstructed, and test findings is just qualified at last.Testing like this to prove that the tripping operation contact could export through the tripping operation pressing plate, but can not verify to have or not parasitic loop, a tripping operation contact whether can to export through the tripping operation pressing plate of other outlet loops that trip between the tripping operation outlet loop.
Summary of the invention
The technical problem to be solved in the present invention is; a kind of protection tripping operation outlet loop test method is provided, and can not verifying that prior art exists has or not parasitic loop between the tripping operation outlet loop, whether a tripping operation contact can be through the deficiency such as tripping operation pressing plate outlet of other outlet loops that trip to overcome.
Technical scheme of the present invention is: it may further comprise the steps: it may further comprise the steps: the first step, drop into the tripping operation pressing plate of arbitrary tripping operation outlet loop, and allow the protective device action, measure this tripping operation outlet loop for lead to multimeter this moment; Second step; when withdrawing from the tripping operation pressing plate of this tripping operation outlet loop, drop into every other tripping operation pressing plate; allow protective device move once more; measure this tripping operation outlet loop with multimeter; according to logical and obstructed two kinds of situations of this tripping operation outlet loop, whether the tripping operation contact to this tripping operation outlet loop can export through the tripping operation pressing plate of other outlet loops that trip, has or not parasitic loop to judge between trip(ping) circuit respectively.
In second step, it is obstructed measuring this tripping operation outlet loop with multimeter, and the tripping operation contact that then is judged as this tripping operation outlet loop can not export through the tripping operation pressing plate of other outlet loops that trip, do not have parasitic loop between trip(ping) circuit, judges that promptly this test findings is qualified.
In second step, measure this tripping operation outlet loop for logical with multimeter, the tripping operation contact that then is judged as this tripping operation outlet loop can export through the tripping operation pressing plate of other outlet loops that trip, parasitic loop is arranged between trip(ping) circuit, judges that promptly this test findings is defective.
Beneficial effect of the present invention is: in the test method second of prior art goes on foot, even to measure the tripping operation outlet loop obstructed withdrawing under the situation of all pressing plates, can not prove that the tripping operation contact of this tripping operation outlet loop can not export through the tripping operation pressing plate of other outlet loops that trip.In second step of the present invention, be to drop at the tripping operation pressing plate that withdraws from this tripping operation outlet loop that to measure this tripping operation outlet loop under the situation of other all tripping operation pressing plates be obstructed, the tripping operation contact that then can prove this tripping operation outlet loop can not have parasitic loop through the tripping operation pressing plate outlet of other outlet loops that trip between trip(ping) circuit.Thereby guarantee the correctness of this test method.
Description of drawings
Fig. 1 is a synoptic diagram of the present invention.
Embodiment
Embodiments of the invention: test method of the present invention changed second step of existing test method, promptly when withdrawing from the tripping operation pressing plate of this tripping operation outlet loop, drop into every other tripping operation pressing plate, allow protective device move, if measure this tripping operation outlet loop with multimeter this moment is obstructed, the tripping operation contact that so just can prove this tripping operation outlet loop can be through the tripping operation pressing plate outlet of other outlet loops that trip, do not have parasitic loop between trip(ping) circuit, it is qualified promptly to be judged as; If measure this tripping operation outlet loop for logical with multimeter this moment, so just can prove that the tripping operation contact of this tripping operation outlet loop may have parasitic loop through the tripping operation pressing plate outlet of other outlet loops that trip between trip(ping) circuit, promptly be judged as defective.
1 describe with reference to the accompanying drawings below.As shown in Figure 1, JD1, JD2, JD3, JD4 representative tripping operation contact, YB1, YB2, YB3, YB4 representative tripping operation pressing plate, JD1 connects with YB1 and constitutes tripping operation outlet loop 1, and JD2 connects with YB2 and constitutes tripping operation outlet loop 2, and the like.Explain with check tripping operation outlet loop 1 below, only drop into YB1, allow and protect action JD1 closure, measure tripping operation outlet loop 1 for logical with multimeter this moment, withdraw from YB1 then, drop into YB2, YB3, YB4, allow and protect action JD1 closure, if measure this tripping operation outlet loop 1 with multimeter this moment is obstructed, then this test findings be qualified; If measure this tripping operation outlet loop 1 for lead to multimeter this moment, this then test findings be defective.
