Description
Technical field
The present invention relates to circuit-breaker testing technology, specifically a kind of portable beaker three-phase non-three phase tester movement time.
Background technology
Chopper is in actual motion, if the three-phase non-three phase action tripping of chopper or exceed schedule time movement time, will cause non full phases operation of line, thus have a strong impact on the safe and stable operation of power system.Therefore, in order to ensure the safe and stable operation of power system, need in advance the three-phase non-three phase of chopper to be tested movement time.Under prior art conditions; carrying out the method that above-mentioned test used is to be drawn by the tripping operation contact of the three-phase non-three phase time relay of chopper; and access in reaying protection test equipment; then by reaying protection test equipment simulating actual non-three phase fault, the three-phase non-three phase movement time of chopper is thus calculated.Practice have shown that, existing test method is limited due to self principle, has that working strength is big, inefficiency, a problem that result of the test error is big.Being specifically described as follows: one, during test is carried out, testing crew needs to remove secondary circuit, and after off-test, and testing crew also needs to carry out switching transmission test, thus causes that testing crew working strength is big, inefficiency.Its two, existing test method does not considers the movement time of chopper of the impact on three-phase non-three phase movement time, thus causes result of the test error big.Based on this, it is necessary to invent a kind of brand-new circuit breaker testing device, to solve the problems referred to above that existing circuit-breaker testing method exists.
Summary of the invention
The present invention is to solve that existing circuit-breaker testing method working strength is big, inefficiency, problem that result of the test error is big, it is provided that a kind of portable beaker three-phase non-three phase tester movement time.
The present invention adopts the following technical scheme that realization: a kind of portable beaker three-phase non-three phase tester movement time, sub including cabinet, power supply, four-way relay module, master switch, involution button, a LED charactron timer, the 2nd LED charactron timer, first input end, the second input terminal, the 3rd input terminal, four-input terminal；Wherein, power supply, four-way relay module are mounted on the inner chamber of cabinet；Master switch, involution button, a LED charactron timer, the 2nd LED charactron timer, first input end, the second input terminal, the 3rd input terminal, four-input terminal are mounted on the antetheca of cabinet；The positive power source terminal of the oneth LED charactron timer, the positive power source terminal of the 2nd LED charactron timer are all connected with the positive output end of power supply；The negative power end of the oneth LED charactron timer, the negative power end of the 2nd LED charactron timer are all connected with the negative output terminal of power supply by master switch；Two control signal inputs of the oneth LED charactron timer are connected with by second group of normally-closed contact of four-way relay module and the series arm two ends of the 4th group of normally opened contact concatenation respectively；Two control signal inputs of the 2nd LED charactron timer are connected with by first group of normally-closed contact of four-way relay module and the series arm two ends of the 3rd group of normally opened contact concatenation respectively；Two slot signal inputs of the oneth LED charactron timer two ends with involution button respectively are connected；Two slot signal inputs of the 2nd LED charactron timer two ends with involution button respectively are connected；First input end is connected with the 3rd group of coil and the 4th group of coil of four-way relay module respectively；Second input terminal is connected with second group of coil of four-way relay module；3rd input terminal is connected with first group of coil of four-way relay module；Four-input terminal is connected with the positive output end of power supply.
During use, as it is shown on figure 3, chopper A phase trip position spare contact two ends are connected with first input end and four-input terminal respectively.Chopper B phase trip position spare contact two ends are connected with the second input terminal and four-input terminal respectively.Chopper C phase trip position spare contact two ends are connected with the 3rd input terminal and four-input terminal respectively.Specifically used process is as follows: first, closes master switch, and power supply is thus powered to a LED charactron timer and the 2nd LED charactron timer.Then, the A phase of realistic simulation chopper trips, chopper A phase trip position spare contact closes, the 3rd group of coil of four-way relay module and the 4th group of coil all electric, the 3rd group of normally opened contact and the 4th group of normally opened contact of four-way relay module all close.Now, two control signal inputs of a LED charactron timer are connected, and a LED charactron timer thus starts timing.Meanwhile, two control signal inputs of the 2nd LED charactron timer are connected, and the 2nd LED charactron timer thus starts timing.Now, it is inconsistent that the three-phase non-three phase time relay monitors three phase positions, tripping B phase, C phase after the constant time lag set.Chopper B phase trip position spare contact closes, and second group of coil of four-way relay module obtains electric, and second group of normally-closed contact of four-way relay module disconnects.Now, two control signal inputs of a LED charactron timer disconnect, and a LED charactron timer thus stops timing, and the time that a LED charactron timer shows is the time that after A phase trips, B phase trips.Chopper C phase trip position spare contact closes, and first group of coil of four-way relay module obtains electric, and first group of normally-closed contact of four-way relay module disconnects.Now, two control signal inputs of the 2nd LED charactron timer disconnect, and the 2nd LED charactron timer thus stops timing, and the time that the 2nd LED charactron timer shows is the time that after A phase trips, C phase trips.Shown two times (A phase trip after time of tripping of B phase trip with A phase after time of tripping of C phase) in, longer that time time is the three-phase non-three phase movement time of reality, this time contains the movement time of chopper, therefore obtained result of the test has fully taken into account the movement time of chopper of the impact on three-phase non-three phase movement time.Finally, pressing involution button, two slot signal inputs of a LED charactron timer are connected, and a LED charactron timer is thus zeroed out.Meanwhile, two slot signal inputs of the 2nd LED charactron timer are connected, and the 2nd LED charactron timer is thus zeroed out.Based on said process, compared with existing circuit-breaker testing method, a kind of portable beaker three-phase non-three phase tester movement time of the present invention has the advantage that one, a kind of portable beaker three-phase non-three phase tester movement time of the present invention during test is carried out without secondary circuit is removed, and without carrying out switching transmission test after off-test, and only need to be by chopper A, B, C three-phase trip position spare contact accesses the first-the three input terminal, the three-phase non-three phase of chopper can be tested movement time, thus effectively reduce the working strength of testing crew, it is effectively increased work efficiency.They are two years old, a kind of portable beaker three-phase non-three phase tester movement time of the present invention starts timing after A phase trips, until three-phase just stops timing after all tripping, it has taken into full account the movement time of chopper of the impact on three-phase non-three phase movement time, thus effectively reduces the error of result of the test.In sum, a kind of portable beaker three-phase non-three phase tester movement time of the present invention, by using brand new, efficiently solves that existing circuit-breaker testing method working strength is big, inefficiency, problem that result of the test error is big.
Present configuration rationally, design ingenious, efficiently solve that existing circuit-breaker testing method working strength is big, inefficiency, problem that result of the test error is big, it is adaptable to power system.
