The action process of three-phase breaker is exactly closing coil energization then breaker closing in fact, and opening coil energization is then broken
Road device separating brake.Trip operation and three-phase are closed automatically simultaneously in order to illustrate single-phase manual conjunction trip operation, three-phase manual while being closed
The concrete methods of realizing of trip operation, the present embodiment is so that A phase is illustrated for closing a floodgate.
Assuming that current state A phase separating brake.KL_JA7 (normally closed) and KL_JA3 (normally opened) position contact input are to GOOSE, SV
Parse circuit；KL_JA8 (normally closed) and KL_JA9 (normally opened) position contact input are to Analog control circuit；KL_JA5 (normally closed)
(normally opened) with KL_JA1 is spare space output contact.If so that A phase is closed a floodgate, there are four types of modes:
(1) A phase is closed a floodgate manually, and hand combination switch A junction closure in Fig. 2 makes positive and negative 220V Voltage On state to KL_CA relay
Device, linkage KL_CA1 normally opened contact closure, makes the KL_JA actuating of relay.The KL_JA actuating of relay makes KL_JA4 contact closure,
KL_JA5 normally-closed contact separates, and forms interlocking anti-jump loop.KL_JA1 normally opened contact closure simultaneously connects breaking coil A.
Separate KL_JA6 normally-closed contact when the KL_JA actuating of relay, TWA (A phase jumps a lamp) goes out, KL_JA2 normally opened contact closure, HWA
(A phase coincidence lamp) is bright, and closing operation is completed.When KL_JA1 normally opened contact closure, KL_TA relay electrification movement, KL_TA1
Normally-closed contact separates, and makes KL_JA relay power loss recovery.A phase sub-switching operation and B phase, the division operating principle of C phase are same as above.
(2) manual three-phase closes a floodgate simultaneously, and three-phase combined floodgate, which closes the switch, makes the KL_SH actuating of relay, and link KL_SH1 contact
Closure, A phase, B phase and C phase carry out closing operation simultaneously respectively later, realize that process is identical as single phase closing operating process；Three-phase
Hand trip(ping) operating principle is same as above.
(3) control three-phase in Analog control circuit closes a floodgate, and line current circuit, line voltage distribution are passed through in Analog control circuit
Circuit, busbar voltage circuit and position of the switch contact input amount comprehensive descision, condition are closed a floodgate after meeting to control loop hair three-phase
Order makes the KL_SH actuating of relay, and link KL_SH1 junction closure, and A phase, B phase and C phase carry out combined floodgate behaviour simultaneously respectively later
Make, realizes that process is identical as single phase closing operating process；Automatic trip operating principle is same as above.
(4) GOOSE, SV parse circuit control three-phase and close a floodgate, and the parsing circuit GOOSE, SV is by judging that it is defeated that SV receives optical port
The logical relation for the position of the switch contact that the analog quantity and control loop entered inputs, hair three-phase closes a floodgate to order and give after condition meets
Control loop makes the KL_SH actuating of relay, and link KL_SH1 junction closure, and A phase, B phase and C phase are closed simultaneously respectively later
Lock operation realizes that process is identical as single phase closing operating process.
GOOSE, SV parse circuit can also receive optical port reception breaker tripping and closing order directly to control loop hair by GOOSE
Three-phase closes a floodgate order, makes the KL_SH actuating of relay, and link KL_SH1 junction closure, later A phase, B phase and C phase respectively and meanwhile into
Row closing operation realizes that process is identical as single phase closing operating process；Automatic trip operating principle is same as above.
Perfect in shape and function of the present invention, using simple, various modes are flexibly used, and are carried out to cooperating with Intelligent protection measuring controller
A large amount of total group test.Test result illustrates that this intelligent simulation switch performance index has reached technical requirements, can correctly show
Actual closing position, open position, manual, Analog control circuit and GOOSE, SV parsing circuit can make to simulate divide-shut brake
Coil is correctly acted with protective device, and it is correct that intelligent optical port GOOSE, SV receives transmission information.
It should say that the invention of the present apparatus solves the problems, such as that Intelligent protection measuring controller test is difficult, fill up intelligent power transformation
Protection measuring and controlling equipment of standing can not simulate the technological gap of actual switch in all kinds of inspections detection work；Enrich smart machine event
The means for hindering detection, improve smart machine running quality；Effectively reduce the meaningless frequent divide-shut brake of breaker apparatus
Number, improves the service life of breaker.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, those skilled in the art should understand that, based on the technical solutions of the present invention, those skilled in the art are not
Need to make the creative labor the various modifications or changes that can be made still within protection scope of the present invention.
