Description
Technical field
The utility model relates to a kind of electric system testing equipment, relates in particular to the anti-jump test instrument of a kind of isolating switch, is mainly used in the anti-skip test of isolating switch, belongs to T & D Technology field.
Background technology
So-called jump refers to that closing circuit is due to reasons such as closing by hand or remote control combined floodgate contact adhesions; cause closing circuit output terminal always with switching voltage; if now switch closes a floodgate in faulty line; switch because of fault tripping after; can close again, the tripping again of protection step switch, because be added with switching voltage always at once; switch can close again again, and the phenomenon that now switch can repeat to jump-close is called " jump " of switch.Once switch jumps, can cause switch to damage, serious also can cause switch blast, so the anti-bouncing function requisite function that is switch.
In breaker mechanism, conventionally install the electric trip-preventing that anti-jumping relay realizes isolating switch by anti-pumping circuit additional and jump.
Tradition to the anti-jump test method of isolating switch is: make isolating switch in co-bit, and switching-in spring is energy storage, combined floodgate handle is beaten to co-bit to this time point TRIP (phase-splitting is tested conventionally), if do not close a floodgate after switch separating brake, draw the normally functioning conclusion of anti-jump.
If apply above-mentioned test method, during at a TRIP or by opening button, tripping operation pulse meeting keeps a period of time, and due to auxiliary switch for circuit breaker displacement, closing circuit has been connected, isolating switch can close a floodgate again, and because tripping operation pulse still exists, switch tripping again, now causes switch can again not close a floodgate because switching-in spring does not have energy storage, make switch in gate-dividing state, make testing crew erroneous judgement anti-bouncing function normal.
Because above-mentioned test method is not whether whether move arbitration functions for anti-jumping relay normal, there is the drawback of erroneous judgement, under this background, need special instrument to check anti-jumping relay whether to start to judge that whether the electric trip-preventing of the isolating switch function that jumps is normal.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of isolating switch anti-jump test instrument, solved the test that jumps of isolating switch electric trip-preventing and had the problem of erroneous judgement.
The technical solution of the utility model is as follows:
Integrated fairing, pulse producer and electronic counter in test apparatus case, wherein after the external alternating current 220V power rectifier of fairing for whole device provides power supply, fairing output terminal connects combined floodgate lead-out terminal, relay calibrating terminal, pulse producer and electronic counter; Pulse producer provides separating brake pulse, and the output terminal of pulse producer connects separating brake lead-out terminal; Electronic counter output terminal connects relay calibrating terminal.
Between described fairing and 220V AC power, power switch is set, power switch is arranged on box outer surface.
Described electronic counter display screen is arranged on box outer surface.
Described combined floodgate lead-out terminal, separating brake lead-out terminal and relay calibrating terminal are connected with Universal plug converter.
The utlity model has following advantage
Compared with the traditional anti-skip test of isolating switch, by the lasting switching voltage of instrument output and pulse separating brake voltage be applied directly to respectively isolating switch point, in closing circuit, abandon the mode that needs artificially breaker operator handle to be continued to get to closing position in original test, reduce the interference of human factor, truer, reliable to the simulation of fault.Adopt pulse singaling to realize to the separating brake of isolating switch in addition, duration of pulse and control interpulse period rationally, if find that isolating switch anti-pumping circuit is malfunctioning in test, can stop test in time, reduce isolating switch jump isolating switch is brought to infringement.
This test apparatus possesses the function whether anti-jumping relay of test moves, test point more directly, clearly, compared with only observing the mode whether isolating switch jump in original test, got rid of due to separating brake voltage continue and the spring erroneous judgement that disturbing factor such as energy storage does not in time bring may.Action situation in conjunction with switch comprehensively judges, makes test findings more reliable, accurate.
Meet after isolating switch is installed and must carry out transmission to the anti-jumping relay in its secondary circuit, and ensure to close under fault condition isolating switch and can not occur artificial hand the requirement of jump phenomena.
Brief description of the drawings

In figure, 1, power switch, 2, fairing, 3, pulse producer, 4, electronic counter, 5, combined floodgate lead-out terminal, 6, separating brake lead-out terminal, 7, relay calibrating terminal.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present utility model in detail.
Embodiment
As shown in Figure 1, integrated fairing, pulse producer and electronic counter in test apparatus case, wherein after the external alternating current 220V power rectifier of fairing for whole device provides power supply, fairing output terminal connects combined floodgate lead-out terminal, relay calibrating terminal, pulse producer and electronic counter; Pulse producer provides separating brake pulse, and during for test, for isolating switch provides separating brake power supply, the output terminal of pulse producer connects separating brake lead-out terminal; Electronic counter output terminal connects relay calibrating terminal; Electronic counter, for reacting the action situation of anti-jumping relay, shows by counting intuitively whether observe anti-jumping relay moves, with accuracy and the reliability of warranty test result.
Between described fairing and 220V AC power, power switch is set, power switch is arranged on box outer surface.Described electronic counter display screen is arranged on box outer surface.Described combined floodgate lead-out terminal, separating brake lead-out terminal and relay calibrating terminal are connected with Universal plug converter.
The test method of the anti-jump test instrument of the utility model isolating switch comprises the steps, for isolating switch provides two-way power supply, wherein a road is lasting 220V positive electricity, is applied to the closing circuit of isolating switch, one tunnel is the pulse power of amplitude 220V, and the duration of pulse is less than 30ms; Be applied to the sub-gate circuit of isolating switch, the a pair of normal opened contact of anti-jumping relay is serially connected in to electronic counter loop simultaneously, make isolating switch in closing position, and switching-in spring energy storage is complete, now start test, pulse producer starts to send pulse to sub-gate circuit, breaker open operation, now be continuously applied switching voltage at closing circuit, if anti-pumping circuit is normal, the anti-jump actuating of relay, disconnect closing circuit, switch will no longer close a floodgate, and electronic counter is under the effect of pulse voltage simultaneously, and counting shows will increase by 1; If anti-pumping circuit has fault or anti-jumping relay to be failure to actuate, will there is jump phenomena in switch, and the numerical value of electronic counter also can not change simultaneously.
