Beneficial effect: this device simplicity of design, be easy to realize, can realize a distant place, local operation function, there is passive site output contact, can be used as the stimulated replacement product of isolating switch in the work such as teaching, test.
brief description of the drawings:
Fig. 1 is principle stretch-out view of the present utility model.
embodiment:
Below in conjunction with accompanying drawing and enforcement, the utility model is further illustrated.
In Fig. 1, K1～4 represent auxiliary reclay; HD represents closing position pilot lamp, and LD represents open position pilot lamp, and JD represents position indicator on the spot, and YD represents remote location pilot lamp; HA represents the test button that closes a floodgate, and FA represents separating brake test button, and JA represents to select on the spot button, YA to represent distant place selection button.
Terminal one connects direct current+220 volt power supply, and terminal two connects direct current-220 volt power supply, and terminal three connects distant place closing operation output contact, and terminal four connects distant place sub-switching operation output contact.Terminal five, six and terminal seven, eight are respectively this mimic-disconnecting switch output normal opened contact, normally closed contact.
operating principle:
1, gate-dividing state: after this device terminals one or two is connected with the mains, this device is in gate-dividing state.Now the normally closed contact K34 of auxiliary reclay K3, in closure state, lights LD open position pilot lamp; The normally closed contact K46 of auxiliary reclay K4, in closure state, lights YD remote operation position indicator, and normally closed contact K43, K44, in closure state, can accept the remote operation instruction from terminal three, four at any time.Normally closed contact K11 and K21 are respectively the contacts of auxiliary reclay K1 and K2, and effect is to realize interlock function, make point, closing circuit conducting simultaneously.
2, distant place closing operation: when mimic-disconnecting switch is during in remote operation, open position, terminal three receives and closes a floodgate after order, auxiliary reclay K1 is by the charged action of normally closed contact K31, K21, its normal opened contact K12 closure makes the charged action of auxiliary reclay K3, normal opened contact K33 closure realizes K3 self-sustaining, normally closed contact K31 disconnects K1 closing circuit, normal opened contact K32 closure, conducting sub-gate circuit, wait for separating brake order, normally closed contact K34 disconnects LD open position pilot lamp, and normal opened contact K35 closure is lighted HD closing position pilot lamp.Now mimic-disconnecting switch is in "on" position.
3, distant place sub-switching operation: in the time of mimic-disconnecting switch remote operation, closing position, terminal four receives after separating brake order, auxiliary reclay K2 is by closed normal opened contact K32, the charged action of normally closed contact K11, its normally closed contact K22 disconnects auxiliary reclay K3 power-off is returned, its normal opened contact K33 disconnects and removes K3 self-sustaining, the closed conducting K1 of normally closed contact K31 closing circuit, wait for the order of closing a floodgate, normal opened contact K32 disconnects K2 sub-gate circuit, normally closed contact K34 closure is lighted LD open position pilot lamp, and normal opened contact K35 disconnects HD closing position pilot lamp.Now mimic-disconnecting switch is in gate-dividing state.
4, local operation: when mimic-disconnecting switch is during in remote operation, press button JA on the spot, auxiliary reclay K4 is charged, its normal opened contact K45 closure realizes self-sustaining, normally closed contact K43, K44 disconnect remote operation loop, and the closed local operation loop of connecting of normal opened contact K41, K42 is pressed switch knob HA and can be carried out closing operation in the time of open position, in the time of closing position, press opening button FA and can carry out sub-switching operation, principle is with distant place breaking-closing operating.
5, a distant place/local operation switches: in the time of local operation position, press remote operation button YA, auxiliary reclay K4 power-off, normal opened contact K45 disconnects auto-lock function, normal opened contact K41, K42 disconnect local operation loop, the closed remote operation loop of connecting of normally closed contact K43, K44.Vice versa.
