Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is the electrical schematic diagram of the utility model mimic-disconnecting switch.
Embodiment
See shown in Figure 1; the mimic-disconnecting switch of the utility model protection tester comprises three independently mimic-disconnecting switch DL1; DL2 and DL3 and operating power; operating power is connected with the power end of every mimic-disconnecting switch respectively; every mimic-disconnecting switch has corresponding separating brake and reclosing command input port; separating brake and combined floodgate preset port and output normally closed contact port or normal opened contact port; the separating brake of every mimic-disconnecting switch and reclosing command input port and output normally closed contact port or normal opened contact port are connected with automatic bus, and separating brake presets port with combined floodgate and is connected with central processing unit.Each mimic-disconnecting switch of the present utility model includes closing relay J1 and separating brake relay J 2, see mimic-disconnecting switch DL1 shown in Figure 2, on the loop of the normally closed interlock serial connection separating brake relay J 2 of closing relay J1, on the loop of the closing relay J1 of the normally closed interlock serial connection of separating brake relay J 2, and the interlock of the normally open contact of closing relay J1 and mimic-disconnecting switch.When the outside or inner closure earlier of closing a floodgate, closing relay J1 action, this moment is because the separating brake open circuit, the normally closed interlock closure of separating brake relay J 2, the normally open contact of closing relay J1 is by closing relay J1 self-sustaining, at this moment another normally open contact DL1 closure of closing relay J1 is exported normally closed signal; When the separating brake closure, 2 actions of separating brake relay J, the normally closed interlock open circuit of separating brake relay J 2, the self-sustaining of lock relay J 1 was lost efficacy, at this moment normally open contact DL1 opens a way, signal is often opened in output, the normally closed interlock closure of closing relay J1, and a normally open contact of separating brake relay J 2 can allow 2 self-sustainings of separating brake relay J.And when outside or inner separating brake elder generation closure, 2 actions of separating brake relay J, this moment is because the open circuit that closes a floodgate, the normally closed interlock closure of closing relay J1, a normally open contact of separating brake relay J 2 is by 2 self-sustainings of separating brake relay J, at this moment the normally open contact DL1 of separating brake relay J 2 open circuit is exported and is often opened signal; Closed if close a floodgate, closing relay J1 action, the normally closed interlock open circuit of closing relay J1, the self-sustaining of separating brake relay J 2 was lost efficacy, at this moment DL1 closure, export normally closed signal, the normally closed interlock closure of separating brake relay J 2, the normally open contact of closing relay J1 can allow relay 1 self-sustaining.
See Fig. 1, shown in 2, mimic-disconnecting switch DL1 of the present utility model, the normally open contact A1 of DL2, A2 is serially connected on the voltage output line respectively, the normally open contact A3 of simulation road device DL3 is connected across the output terminal of normally open contact A1 and normally open contact A2, two gauge tap K1 and K2 respectively with mimic-disconnecting switch DL1, the normally open contact A1 of DL2, the A2 serial connection, owing to make mimic-disconnecting switch simulate interior ridge method fully, each normally open contact A1, A2 and A3 respectively with separately closing relay J1 interlock, form logical combination, the voltage that output is set by the gauge tap K2 and the normally open contact of respectively simulating the road device.And also be parallel with hand switch SK1 on the branch road open circuit being connected in series of normally open contact A1 of DL1 of gauge tap K1 and simulation, gauge tap K2 also is parallel with hand switch SK2 with being connected in series of normally open contact A2 of simulating the DL2 that opens circuit on the branch road, also can control the voltage that output is set manually.See shown in Figure 2, the utility model also has normally closed switch failure contact C1 on closing relay J1, separating brake relay J 2 has the malfunctioning contact C2 of normally closed separating brake, when the mimic-disconnecting switch switch failure, mimic-disconnecting switch is response external and inner energization control signal not, when separating brake was malfunctioning, mimic-disconnecting switch is response external and inner separating brake control signal, mimic-disconnecting switch malfunction well not equally.Divide-shut brake instruction the carrying out divide-shut brake that three mimic-disconnecting switches of the present utility model are accepted to send tested automatic bus outside moves, also receive central processing unit and send inner default divide-shut brake instruction carrying out divide-shut brake action, and by the normally closed or normal opened contact port of output to tested automatic bus output respective switch amount, wiring is simple, easy to operate, can satisfy the verification work of electric system internal bridge automatic bus.
