Embodiment
the utility model utilizes electronic withdrawable parts to switch the characteristics that must make withdrawable position component state auxiliary switch action when putting in place in test position and service position; The position auxiliary switch is penetrated the control loop of other electronic withdrawable parts, thereby realize the logical operation order of many electronic withdrawable parts (handcart functional unit).The control loop of the electronic withdrawable parts of the utility model is: control is used to drive the loop that gets electric or dead electricity of the motor (control motor) of electronic withdrawable parts.The motor of withdrawable parts gets electric, and withdrawable parts just can move between service position and test position, and arrives service position or test position; The motor dead electricity of withdrawable parts, withdrawable parts just can not move, thereby are stopped at service position or test position.
Fig. 1 a and Fig. 1 b are asked for an interview in
; This illustrated " two advance one ": i.e. two electronic withdrawable parts---circuit breaker; Controlling the motor M 1 of first circuit breaker connects with the test position normally closed auxiliary contact of second circuit breaker; Promptly connect (Fig. 1 a shows), control the motor M 2 of second circuit breaker and connect, promptly connect (Fig. 1 b shows) with the second auxiliary contact S1 with the test position normally closed auxiliary contact of first circuit breaker with the first auxiliary contact S2.When wherein one one leave test position, other one control loop is disconnected, thus circuit breaker can not leave test position, has only after the circuit breaker that leaves test position is got back to test position this just can leave test position and gets into the service position.Thereby realize that two advance a function.
Fig. 2 a, 2b and 2c are asked for an interview in
; (present embodiment is three circuit breakers to three electronic withdrawable parts; To call first, second, third circuit breaker in the following text) three advance two and realize as follows; The test position normally closed auxiliary contact of second circuit breaker be the aforesaid first auxiliary contact S2 with the test position normally closed auxiliary contact of the 3rd circuit breaker promptly the 3rd auxiliary contact S3 parallelly connected after, connect (Fig. 2 a shows) with the control motor M 1 of first circuit breaker again; The test position normally closed auxiliary contact of first circuit breaker promptly the second auxiliary contact S1 and the test position normally closed auxiliary contact of the 3rd circuit breaker be the 3rd auxiliary contact S3 parallelly connected after, connect (Fig. 2 b shows) with the control motor M 2 of second circuit breaker again; The test position normally closed auxiliary contact of first circuit breaker promptly the second auxiliary contact S1 and the test position normally closed auxiliary contact of second circuit breaker be the first auxiliary contact S2 parallelly connected after, connect (Fig. 2 c shows) with the control motor M 3 of the 3rd circuit breaker again.The control motor of that circuit breaker of residue can't get electricly after any two circuit breakers get into the service position, is locked in test position.Thereby realize that three advance two functions.
Fig. 3 a and 3b are asked for an interview in
; The operation sequence of " A is advanced, and B advances again; B goes out A earlier and goes out ": as two electronic withdrawable components A, B; (present embodiment is the function handcart to electronic withdrawable components A; Isolating handcart or PT handcart etc.) service position normally closed auxiliary contact SA connects with the control motor of electronic withdrawable part B (present embodiment is a circuit breaker), and the control motor of the test position normally closed auxiliary contact of withdrawable part B (circuit breaker) and withdrawable components A (present embodiment is function handcart-isolation handcart or PT handcart etc.) is connected.Thereby have only the control electric motor loop of withdrawable part B (circuit breaker) after withdrawable components A (present embodiment is function handcart unit-isolation handcart, PT handcart etc.) enters into the service position to be switched on; Withdrawable part B (circuit breaker) can be left test position, enters into the service position; Move to test position and have only after withdrawable part B is left the service position to get back to test position withdrawable components A just can leave the service position.SA among Fig. 3 a is a function handcart A service position normally closed auxiliary contact, and MB is the motor that is used to drive circuit breaker; SB among Fig. 3 b is the test position normally closed auxiliary contact of circuit breaker, and MA is the motor that is used to drive function handcart A.
Fig. 4 is asked for an interview in
, to forbid isolating handcart under the lead-in circuit breaker combined floodgate situation and leaves service position (originally being positioned at the service position) in order to be implemented in, and the normally closed auxiliary switch QF of lead-in circuit breaker is in series with the motor of isolating the handcart functional unit.The breaker closing of interlocking does not allow to isolate the handcart functional unit in addition later on and leaves the service position mutually.After the breaker closing, the auxiliary switch for circuit breaker action, normally closed often converting into opened, thereby isolates the motor dead electricity of handcart functional unit, so be locked in the service position, the M among Fig. 4 is for isolating the motor of handcart functional unit
