Abstract
The utility model discloses a test device of a vacuum circuit breaker, characterized by being composed of an analog circuit and a matching device. The matching device sends a vacuum circuit breaker closing control signal or tripping control signal to the analog circuit, and the analog circuit returns a vacuum circuit breaker closing loop signal or tripping loop signal to the matching device. By employing the above structure and utilizing an analog breaker formed by cooperating a relay work principle and a large power resistor, the work full process of a high voltage breaker is simulated, and the relay protection project examination is cooperated; by the same tripping/ closing 1-5 ampere current as that of an actual high voltage vacuum circuit breaker, the reliability of the current keep loop of a relay protection tripping/ closing device is examined; and by employing a economic and feasible mode to simulate the function of the vacuum circuit breaker, the test device is small in volume and power consumption, light in weight, stable in performance and good in anti-interference performance, and can be operated repeatedly.
Description
Technical field
The claimed technical scheme of the utility model relates to a kind of proving installation of vacuum circuit breaker.
Background technology
In the work for inspection of electric system microcomputer protective relay device; Correctness for the check circuit; Must microcomputer protective relay device and high-pressure vacuum breaker be connect and carry out the breaker tripping and closing test; Yet in real work, often run into high-pressure vacuum breaker also in maintenance or other reason situation that can't cooperate synchronously, particularly when infrastructure project debug, protective relaying device has been debugged and has been finished and situation often generation especially that high-pressure vacuum breaker does not also install.Because the appearance of these situation is affected relay protection debugging work.Simultaneously, the operate high pressure vacuum circuit breaker also can influence its operation life too continually, even the damage that 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 the market is various in style; But great majority can not be used with the microcomputer type relay protection proving installation; The simulated high-pressure vacuum circuit breaker price that can be used on a small quantity is generally higher again, and reliability and anti-interference are relatively poor, and volume moves very inconvenient greatly.
The utility model content
The utility model technical matters to be solved provides a kind of proving installation of vacuum circuit breaker, to reach the overall process of simulated high-pressure vacuum circuit breaker work, cooperates the purpose of the project check of relay protection.
For solving the problems of the technologies described above; The technical scheme of the utility model is a kind of proving installation of vacuum circuit breaker; It is characterized in that; Described proving installation is made up of mimic channel and corollary apparatus, and described corollary apparatus sends the vacuum circuit breaker energization control signal or tripping operation controls signal to mimic channel, and mimic channel returns vacuum circuit breaker closing circuit signal or trip(ping) circuit signal to corollary apparatus.
Described mimic channel is made up of relay HC, TC, ZJ and resistance R 1; The energization control signal of corollary apparatus is connected with the coil of relay HC through the normally closed contact of relay ZJ; The tripping operation control signal of corollary apparatus is connected with the coil of relay TC through the normally opened contact of relay ZJ; Resistance R 1 of relay TC coil two ends parallel connection, power supply is connected with the coil of relay ZJ through 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 adopt said structure, utilizes the relay principle of work to cooperate the mimic-disconnecting switch of forming with high-power resistance; The overall process of simulated high-pressure isolating switch work cooperates the project check of relay protection, through the breaker tripping and closing electric current 1～5A identical with the actual high-voltage vacuum circuit breaker; Keep the reliability in loop with check relay protection breaker tripping and closing device electric current, 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; In light weight, power consumption is little, but repeatable operation; Stable performance, anti-interference is good
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation;
Fig. 1 is the proving installation structured flowchart of the utility model vacuum circuit breaker;
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 made up of mimic channel 2 and 1 of corollary apparatus; 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 vacuum circuit breaker closing circuit signal or trip(ping) circuit signal to corollary apparatus 1.
As shown in Figure 2; Mimic channel; Form by 2 electromagnetic type relay MY2N-J, 1 electromagnetic type relay MY4N-J, high-power resistance R1; According to the working power (like AC220V/DC220V/DC110V) of 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 the combined floodgate outlet and the tripping operation outlet of mimic channel respectively; The normal battle of electrical equipment ZJ is succeeded in the outlet of closing a floodgate, and the normally closed point of electrical equipment ZJ is succeeded in the tripping operation outlet, the parallel connection high-power resistance R1 (60W/1K) at relay TC coil two ends; 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, let the relay TC can regular event, the anti-jump function of its corollary apparatus can normally realize 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 break off 11 and 3 contacts, 4 and 12 junction closures.When corollary apparatus 1 was given a closing pulse signal through the outlet of closing a floodgate, relay HC closing coil got electric, realizes 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 tripped pulse signal through the tripping operation outlet to one, relay TC coil got electric, the simulation trip avoidance function; The normally closed point of relay TC breaks off simultaneously, relay ZJ dead electricity, and 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 accomplish deciliter operation cycle.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
