Description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
A kind of microcomputer protecting device, protecting circuit built in microcomputer protecting device, anode connects through diode HR in circuit
Trip supervisory relay KTP, and tripping supervisory relay KTP meets closing coil YC through normal open switch QF1, and closing coil YC connects power supply
Cathode, positive pole meet normally closed switch KLT.V through normal open switch KLC, and normally closed switch KLT.V is through normally closed switch KPLC contact relays
KLC, relay KLC meet normal open switch QF1, and positive pole is through normal open switch KRR contact pin XB in succession, connection sheet XB contact relays
KLT.V, relay KLT.V connect power cathode through normal open switch KLT.A and normal open switch KLT.V respectively, and positive pole connects respectively
The port 1 and 5 of current coil SA, the port 2 of current coil SA is through diode D1 contact relay KLT.V, the end of current coil SA
Mouth 6 meets diode D1 through normal open switch KRC, and the port 6 of current coil SA connects diode D2, while electric current through normal open switch KRT
The port 12 of coil SA meets diode D2, diode D2 contact relay KLT.A, and positive pole succeeds electricity through normal open switch KLT.A
Device KLT.A, relay KLT.A meet breaking coil YT through normally closed switch QF1, and breaking coil YT connects power cathode, positive pole warp
Diode HG contact relay KCP, relay KCP meet normally closed switch QF1, and positive pole through normal open switch KTC and normally opened is opened respectively
It closes KTP and meets indicator light HLC and indicator light HLT, indicator light HLC and indicator light HLT are respectively through normal open switch QF2 and normally closed switch
QF2 connects power cathode.
Photoelectrical coupler built in indicator light HLC and indicator light HLT, and use TLP521 type photoelectrical couplers.
Decision logic to control circuit state is：Optocoupler components in HLC indicator lights, HLT indicator lights are cut in HLT
Only, when HLC is turned on, it is judged as closing a floodgate；In HLT conductings, HLC cut-offs, it is judged as separating brake；When HLC, HLT end, sentence
Disconnected circuit in order to control breaks.
When microcomputer protecting device is run, after trip command is sent, remote control tripping relay KRT normally opened contacts are closed, and are jumped
Lock guard relay current coil KLT.A starts, and KLT.A normally opened contacts are closed, and breaker normally closed switch QF1 is closed, and trip line
It encloses YT to start, is consequently formed trip circuit；After breaker is completed to trip, QF1 disconnection trip circuits, KLT.A and YT dead electricity,
KLT.A normally opened contacts disconnect；When tripping occurs for breaker, trip circuit is charged for a long time, and KLT.A normally opened contacts are being closed at this time
Position, the short circuit HLC of combined floodgate monitoring circuit and combined floodgate supervisory relay KCP so that HLC lamps extinguish, due in combined floodgate circuit often
It switchs QF1 and disconnects position, the monitoring circuit that trips has been connected access with trip-preventing circuit, and tripping supervisory relay KTP and tripping are protected
It holds relay voltage coil KLT.V to divide circuit, because KLT.V gets undertension with by KLT.V normally-closed contacts
It disconnects, so HLT lamps are still bright；According to control circuit condition adjudgement logic, it is judged as tripping, but circuit is susceptible to malfunction,
Therefore in indicator light HLT both ends parallel resistance R1, so as to prevent circuit malfunction, circuit stability operation is ensured.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new introduction, in the case where not departing from the principle of the utility model with spirit, the change that is carried out to embodiment is repaiied
Change, replace and modification is still fallen within the scope of protection of the utility model.
