Abstract
The invention discloses a testing arrangement of a vacuum circuit breaker which is characterized in that: the testing arrangement is composed of an analog circuit and a matching apparatus, the matching apparatus sends a vacuum circuit breaker closing control signal or a trip-out control signal to the analog circuit, and the analog circuit returns a vacuum circuit breaker closing loop signal or a trip-out loop signal to the matching apparatus. Since the above structure is employed, by utilizing cooperation of a relay working principle and a large power resistor, an analog breaker is formed to simulate the whole working process of a high-voltage circuit breaker, combined with project examination of relay protection, through tripping and closing current 1-5A identical to the tripping and closing current of a real high-voltage vacuum circuit breaker, reliability of relay protection tripping and closing current maintenance loops is examined, and an economical and feasible mode is employed to realize a function of an analog vacuum circuit breaker. The testing arrangement has the advantages of small volume, light weight, small power consumption, repeatable operation, stable performance and good anti-interference performance.
Description
Technical field

Background technology
In electric system microcomputer protective relay device check work; correctness for the check circuit; microcomputer protective relay device and high-pressure vacuum breaker must be tied and carry out the breaker tripping and closing test; yet often run into high-pressure vacuum breaker also in the situation of overhauling or other reason can't synchronously coordinate in real work; particularly when infrastructure project was debugged, protective relaying device had been debugged complete and situation often generation especially that high-pressure vacuum breaker does not also install.Due to the appearance of these situations, Commissioning of Relay Protection work is affected.Simultaneously, the operate high pressure vacuum circuit breaker also can affect its operation life too continually, and damage even can meet accident.Therefore, develop mimic-disconnecting switch and be very important, some reaying protection test chambers or professional manufacturing plant are urgent especially to the demand of mimic-disconnecting switch.
At present; the simulated high-pressure vacuum circuit breaker of selling on market is various in style; but great majority can not be used in conjunction with Computer Typed Relay-protection Equipment; the simulated high-pressure vacuum circuit breaker price that can be used in conjunction with on a small quantity is generally higher again; reliability and anti-interference are relatively poor, and the large movement of volume is got up very inconvenient.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of proving installation of vacuum circuit breaker, to reach the overall process of simulated high-pressure vacuum circuit breaker work, coordinates the purpose of the project check of relay protection.
For solving the problems of the technologies described above, technical scheme of the present invention is a kind of proving installation of vacuum circuit breaker, it is characterized in that, described proving installation is comprised of mimic channel and corollary apparatus, described corollary apparatus sends the vacuum circuit breaker energization control signal or tripping operation controls signal to mimic channel, and mimic channel returns to vacuum circuit breaker closing circuit signal or trip(ping) circuit signal to corollary apparatus.
Described mimic channel is comprised of relay HC, TC, ZJ and resistance R 1, the energization control signal of corollary apparatus is connected with the coil of relay HC by the normally closed contact of relay ZJ, the tripping operation control signal of corollary apparatus is connected with the coil of relay TC by the normally opened contact of relay ZJ, relay TC coil two ends resistance R 1 in parallel, power supply is connected with the coil of relay ZJ by the normally opened contact of relay TC normally closed contact and relay HC.
Described corollary apparatus is microcomputer protective relay device or conventional test equipment.
a kind of proving installation of vacuum circuit breaker, owing to adopting said structure, utilize the mimic-disconnecting switch of relay principle of work and high-power resistance mix proportion, the overall process of high voltage breaker simulator work, coordinate the project check of relay protection, by the jumping identical with the actual high-voltage vacuum circuit breaker, switching current 1～5A, jump with the check relay protection, the closing device electric current keeps the reliability in loop, adopt a kind of economically viable mode to realize simulating the function of vacuum circuit breaker, it is little that this proving installation has a volume, lightweight, power consumption is little, but repeatable operation, stable performance, anti-interference is good
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments;
Fig. 1 is the proving installation structured flowchart of a kind of vacuum circuit breaker of the present invention;
Fig. 2 is mimic channel circuit theory diagrams shown in Figure 1;
In Fig. 1,1, corollary apparatus; 2, mimic channel.
Embodiment
As shown in Figure 1, a kind of proving installation of vacuum circuit breaker, proving installation is comprised of mimic channel 2 and corollary apparatus 1, described corollary apparatus 1 sends the vacuum circuit breaker energization control signal or tripping operation controls signal to mimic channel 2, and mimic channel 2 returns to vacuum circuit breaker closing circuit signal or trip(ping) circuit signal to corollary apparatus 1.
As shown in Figure 2, mimic channel, formed by 2 electromagnetic type relay MY2N-J, 1 electromagnetic type relay MY4N-J, high-power resistance R1, working power (as AC220V/DC220V/DC110V) according to different corollary apparatus, select the relay of different operating power supply next supporting, its operation circuit is identical.The energization control signal of corollary apparatus 1 or tripping operation control signal connect respectively combined floodgate outlet and the tripping operation outlet of mimic channel, the normal battle of electrical equipment ZJ is succeeded in the outlet of closing a floodgate, the normally closed point of electrical equipment ZJ is succeeded in the tripping operation outlet, at a relay TC coil two ends high-power resistance R1 (60W/1K) in parallel, the effect of its resistance R 1 is in order to reduce the dividing potential drop of trip(ping) circuit, increase the distribution voltage of corollary apparatus 1, allow the relay TC can regular event, the anti-bouncing function of its corollary apparatus can normally be realized simultaneously.
When the outlet of closing a floodgate, when the tripping operation outlet does not have pulse voltage signal to come, relay ZJ 8 and 12 contacts, 6 and 10 contacts, 5 and 9 contacts disconnect, 11 and 3 contacts, 4 and 12 junction closures.When corollary apparatus 1 exported to a closing pulse signal by combined floodgate, relay HC closing coil got electric, realized the simulation closing function, the relay HC closure of often making war simultaneously, relay ZJ coil gets electric, and relay ZJ contact 6 and 10 junction closures keep relay ZJ; Normal 8 and 12 junction closures of making war of relay ZJ, the output switching signal, its 5 and 9 junction closure is for next step trip operation is ready to the loop.
When corollary apparatus 1 exports to a tripping operation pulse signal by tripping operation, relay TC coil gets electric, the simulation trip avoidance function, the normally closed point of relay TC disconnects simultaneously, relay ZJ dead electricity, normal 8 and 12 contacts of making war of relay ZJ, 6 and 10 contacts, 5 and 9 contacts are opened, normally closed point 4 and 12 closures of relay ZJ, output trip signal, its 11 and 3 junction closures of often making war, for new round closing operation is ready to the loop, thereby complete a deciliter operation cycle.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
