[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, it is the electrical block diagram of a kind of embodiment of a kind of protective relaying device of the utility model tripping operation outlet proving installation.
A kind of protective relaying device tripping operation outlet proving installation, comprise: the power circuit that direct supply 101 is connected with reset switch 102 and at least one trip and export display circuit, the described tripping operation outlet input end of display circuit and tested protective relaying device pressing plate A export that trip is connected, and the described feeder ear exporting display circuit that trips is connected with power circuit;
Wherein, described tripping operation outlet display circuit comprises photoelectrical coupler, relay 105 and pilot lamp 108; Described photoelectrical coupler comprises light source 103 and phototriode 104; Described relay 105 comprises the first normally opened contact 106 and the second normally opened contact 107;
Described light source 103 one end is connected with tested pressing plate, other end ground connection; The collector of described phototriode 104 is connected with power circuit positive pole; Described phototriode 104 emitting stage connects one end of described first normally opened contact 106, one end of the second normally opened contact 107 and the negative pole of power circuit respectively; The other end of described first normally opened contact 106 is connected with the positive pole of power circuit; The other end of described second normally opened contact 107 is connected with power circuit positive pole through pilot lamp 108.
In the utility model; if tested protective relaying device has tripping operation there is action in outlet; potential pulse then on pressing plate can emit beam by driving light source 103; phototriode 104 detects transient switching after described light; thus relay 105 can be charged instantaneously; now the first normally opened contact 106 and the second normally opened contact 107 close, and pilot lamp 108 is lighted.After potential pulse flows through, phototriode 104 ends, now due to the first normally opened contact 106 closed after define the self-sustaining conducting loop of relay 105, relay 105 is continued charged, second normally opened contact 107 continues closed, thus keeps pilot lamp 108 to light.When tester presses reset switch 102, be that reset switch 102 disconnects, now relay 105 dead electricity, the first normally opened contact 106 and the second normally opened contact 107 disconnect, and pilot lamp 108 extinguishes.
What the utility model can extend pilot lamp 108 lights the time, thus tester can be facilitated to judge, and tripping operation exports whether correct operation, thus avoids repeated test, thus has saved the test duration, improves testing efficiency.
Refer to Fig. 2, it is the electrical block diagram of another embodiment of a kind of protective relaying device tripping operation of the utility model outlet proving installation.
In another real-time example, circuit structure is basic identical with a upper embodiment, and distinctive points is: described light source 103 one end is connected with tested pressing plate, and the other end is through current-limiting resistance R1 ground connection.The other end of described first normally opened contact 106 is connected with the positive pole of power circuit through current-limiting resistance R2.
Increase at the other end of light source 103 stability that current-limiting resistance R1 can increase light source 103, prevent it because amplitude of the potential pulse of pressing plate is excessive and burn out the luminous component of light source 103.Between the first normally opened contact 106 and power circuit, increase current-limiting resistance R2, the stability of relay 105 can be strengthened, prevent relay 105 from burning out because the working time is long and overheated.
Refer to Fig. 3, it is the electrical block diagram of a kind of protective relaying device tripping operation of the utility model outlet proving installation preferred embodiment.
In the preferred embodiment, comprise altogether 10 tripping operation outlet display circuits, described tripping operation outlet display circuit is parallel with one another, and the circuit structure of each tripping operation outlet display circuit is with reference to above two embodiments.Further, described power circuit also comprises: current-limiting resistance R3, and described current-limiting resistance R3 connects with direct supply 101 and reset switch 102.
The utility model preferred embodiment; can once test 10 tripping operation outlets; achieve the complex logic of tester to protective relaying device once to test; volume can judge that tripping operation exports whether correct operation; and without the need to repeated test; just can judge, thus greatly save the test duration, testing efficiency is significantly improved.In addition; by increasing current-limiting resistance R3, protecting the parallel circuit that tripping operation outlet display circuit is formed on the one hand, the stability of the parallel circuit that tripping operation outlet display circuit is formed can be strengthened; the opposing party reduces the electric current of direct supply 101, ensures the power supply safety of DC voltage.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
