Brief description of the drawings
Fig. 1 is the structural representation of circuit breaker operation mechanism;
Fig. 2 is the schematic diagram of the utility model for the detection platform of DC circuit breaker.
Embodiment
Below in conjunction with the drawings and specific embodiments, the detection platform for DC circuit breaker of the present utility model is described in further detail.
As shown in the figure, detection platform for DC circuit breaker of the present utility model, comprise the auxiliary contacts of circuit breaker that can reflect breaker energy storage state 1 arranging in circuit breaker operation mechanism, the circuit breaker failure that can reflect isolating switch deciliter state and whether refuse to close or refuse point fault detects contact 3 and for receiving closing coil 4 and the switching winding 5 of detection signal, wherein, circuit breaker failure detects contact 3 and is connected with push rod 6 by linkage assembly, auxiliary contacts of circuit breaker 1 can trigger the switching-in spring 2 in circuit breaker operation mechanism, auxiliary contacts of circuit breaker 1 is connected with a condition checkout gear 7, circuit breaker failure detects contact 3 and is connected with a failure detector 8, condition checkout gear 7 and failure detector 8 are connected in State-Inspect of High-Voltage Circuit module 9 simultaneously, State-Inspect of High-Voltage Circuit module 9 connects PLC control module M1 by cable respectively, PLC control module M2 and PLC control module M3, PLC control module M1 connects a relay K 1 and can cut-off by pilot relay K1, PLC control module M2 connects a relay K 2 and can cut-off by pilot relay K2, PLC control module M3 connects a relay K 3 and can cut-off by pilot relay K3, relay K 1 connects a closing coil, relay K 2 connects a switching winding, relay K 3 connects a fault alarm, fault alarm has buzzer siren in loop, said State-Inspect of High-Voltage Circuit module 9 is connected on PC, can issue steering order by PC thus.
As shown in Figure 2, L is direct supply bus positive pole to concrete syndeton of the present utility model, and N is direct supply bus negative pole, and M1~M3 is PLC control module, and PC is remote computer; State-Inspect of High-Voltage Circuit module is come monitoring breaker combined floodgate, gate-dividing state or fault trip state by monitoring breaker condition checkout gear 7 and failure detector 8; Between State-Inspect of High-Voltage Circuit module 9 and pick-up unit, transmit data with communication modes; The communication signal of State-Inspect of High-Voltage Circuit module 9 is changed into electric signal by PLC control module M1, PLC control module M2 and PLC control module M3, and often open control inside or the conversion of normally closed contact, relay K 1, relay K 2 and relay K 1 are connected respectively with PLC control module M1, PLC control module M2 and PLC control module M3, and be connected in series with closing coil 4, switching winding 5, buzzer siren respectively, drive breaker mechanical part; This detection platform also can be tested by auxiliary detection breaker mechanic property, as detecting circuit-breaker switching on-off time, speed and not when the same period, PLC control module can provide trigger pip and test signal, realizes divide-shut brake, the energy storage of isolating switch and tests the low-voltage needing.
Its principle of work is as follows:
As shown in Figure 1 and Figure 2, this isolating switch detection platform auxiliary contacts of circuit breaker 1 after breaker energy storage completes turn-offs, and detection platform detects that, after this cut-off signals, closing coil 4 is opened in time delay; After feed motion, auxiliary contacts of circuit breaker 1 conducting, triggers again switching-in spring 2 and carries out energy storage; Circuit breaker failure detects contact 3 and detects current opening and closing state simultaneously, to determine whether to close a floodgate successfully: the unsuccessful phenomenon of refusing to close of closing a floodgate if occur, the State-Inspect of High-Voltage Circuit module 9 of this detection platform is sent to fault-signal PLC control module M3 operation troubles rejected program and starts buzzer siren; If normally close a floodgate, PLC control module M2 presses the delay time triggering switching winding 5 that PC sets, and carries out operating mechanism separating brake; If normal separating brake, auxiliary contact 1 detect isolating switch whether energy storage complete, thereby carry out cycle control.Because this experiment is to detect mechanical life, only need in PC program, input the mechanical endurance test number of times of regulation, this detection platform can realize automatically, unattended operation.
