2A electric current can be passed through in short-term, SYJ is the contact exported in intelligent control module, when switch in closing position and occurs controlling back
When the broken string phenomenon of road, intelligent control module makes SYJ junction closure 10 seconds, sees whether control loop template phenomenon disappears, if disappeared
Mistake then judges to switch auxiliary contact poor contact.
R2 is adjustable resistance (0-10 changes between Europe), and FGJ is anti-trip relay self-sustaining state automatic resetting relay
Device contact, the node are exported by intelligent control, when intelligent control module judgement switch be connected to tripping enable the second several seconds after, protection failure
Electric current IABC, which has disappeared but switched auxiliary contact DL, not to be become also, then turn on automatically FGJ is automatic again after a certain period of time disconnects.
DLJ be trip(ping) circuit switch auxiliary contact Stateful Inspection relay, when switch be in "on" position, if DLJ after
There is the DC voltage of 110V or more in electric appliance both ends, illustrate to switch auxiliary contact poor contact, intelligent control module exports automatically
One docking point DLF is forcibly turned on trip(ping) circuit after connecting with external DL contact, prevents switch failure.
DX1 relay is breaking coil broken string supervisory relay, and when breaking coil broken string, which occurs
220V voltage and act, relay tip DX1 access intelligent control module in, breaking coil is issued by intelligent control module
Disconnection signal.
JD1 is 201 voltage-to-ground supervisory relay of cathode power supply, and when cathode power supply ground connection, which should be after
Electric appliance contact JD1 is linked into intelligent control module.
201,202,235,237,239 in Fig. 5 correspond directly with 201,202,235,237,239 terminals in Fig. 4
It connects in succession.
It is intelligent control module structure chart with reference to Fig. 6, the working power 201,202 of Inverter is taken from Fig. 3's
201,202 terminal.The contact of switching input module input: TJ is derived from the tripping outlet spare contact of protective device；STJ is derived from
The hand trip(ping) relay tip of protective switch operation circuit；WJ is the temperature relay contact being mounted on breaking coil；DX1
For the contact of breaking coil broken string supervisory relay DX1 output in Fig. 5；JD1 is the negative power supply voltage-to-ground monitoring of Fig. 5 output
The contact of relay JD1 output；DL is switch auxiliary contact, exported by switching mechanism after introduce, open one for one and close two contacts.
The input quantity of Analog input mModule: IABC and I0 is bis- three-phase currents of CT and zero sequence of protective device input
Electric current, to judge switch primary current whether disappear, switch whether tripping；I235, I237, I239 distinguish in Fig. 4 235 with
Between 237,237 and DL between, the electric current of current detecting mutual inductor between DL and 239 output.When there is electric current to occur, explanation
The section lead has tripping pulse to occur, this provides recorder data for analysis switch jump reason.
The contact of switching value output module output: FGJ is anti-trip relay self-sustaining state automatic resetting contact, works as intelligence
Control module judgement switch be connected to tripping enable several seconds of second after, protection fault current IABC disappeared but switched auxiliary contact DL
Do not become also, then turn on automatically FGJ is automatic again after a certain period of time disconnects.
DLF is to switch the alternative auxiliary contact exported after auxiliary contact poor contact, if DLJ relay two in Fig. 5
There is the DC voltage of 110V or more in end, illustrates to switch auxiliary contact poor contact, intelligent control module Fig. 6 exports one automatically
To DLF contact.
DX1 contact is breaking coil disconnection signal contact of the output to monitoring system of electric substation.
JD1 is direct-flow positive pole ground connection monitoring contact, and substation's background monitoring system is given in output.
SYJ contact output judge switch auxiliary contact whether the test contact of poor contact.When switch is in closing position
When setting and control loop template phenomenon occur, intelligent control module disconnects again after making SYJ junction closure 10 seconds, sees and controls during closure
Whether circuit breaking phenomenon processed disappears, and judges to switch auxiliary contact poor contact if disappearing.
The self-operating Stateful Inspection contact that contact is intelligent control module output is alerted, when cpu logic error, power supply event
Barrier, the problems such as when, the junction closure, output give substation's background monitoring system, to allow operator to know.
Cpu logic computing module: switch amount input, information the progress logical operation, analysis, recording of analog input
Deng, and finally make to carry out the corresponding command signal of switching value output module output, communicate communication interface module with external.
It is anti-trip relay automatic resetting logic diagram with reference to Fig. 7, when short trouble occurs for system, at the beginning at switch
In coincidence, trip protection contact TJ acts STJ when issuing trip signal or manual brake separating to breaker and acts, after T1 is delayed
Switch is without displacement T (WJ=0), it was demonstrated that switch failure (anti-jump one direct acting of self-holding circuit at this time), after T2 is delayed,
It is returned after 100 milliseconds of the FGJ actuating of relay of driving, during 100 milliseconds of the FGJ actuating of relay, FGJ relay normally closed contact
Anti-trip relay TBJ electric current hold-in winding both ends are connected in parallel on, TBJ loss of excitation involution is made, tripping is disconnected and keeps circuit.
Above-mentioned Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 are achieved that pair after connecting according to digital number and above explained mode
The intelligent control of original switch control circuit effectively prevent burning and because switch auxiliary contact reason causes for switch trip coil
Switch failure accident occur.
