The Centralized Monitoring that is specific to electrification railway contact net disconnecting switch and a kind of distributed integrated automation system for developing.
Disconnecting switch monitoring system is by the master station installed in traction substation and installed in ocs isolating switch machine
Monitoring substation RTU (REMOTE TERMINAL UNIT, remote data terminal) compositions at structure.Master station and monitoring substation
Enter row data communication by optical fiber solutions between RTU, row data communication is directly entered by Ethernet between master station and scheduling.
As a result of the stronger communication mode of antijamming capability, the reliability and security of system are substantially increased.Contact net is isolated
Monitoring switch system realizes the remote moving function of ocs isolating switch.
Existing ocs isolating switch monitoring system disconnecting switch and RTU power supply wirings and air switch set as shown in Figure 2.
Disconnecting switch electric motor loop, performance loop, heating circuit, RTU are provided with air switch, to protect each circuit units and guarantee
Each circuit units are independently-powered.But any one tripping operation, can all cause to connect in 1QF1,1QF2,2QF1, the 2QF2 in air switch
Net-fault disconnecting switch tripping.In addition, remote control separating brakes, remote of the existing ocs isolating switch monitoring system RTU to disconnecting switch
Control shutting-brake control order is realized by single node control loop, as long as shown in figure 3, having control command to issue or having dry
Signal is disturbed, ocs isolating switch can all be acted.
Existing disconnecting switch monitoring system has the following disadvantages：1st, existing ocs isolating switch monitoring system is kept apart
Close electric motor loop, performance loop, RTU and be all provided with air switch, but wherein any one air switch tripping operation, can all cause to connect
Net-fault disconnecting switch tripping, the air switch tripping operation that electric motor loop is particularly in actual motion is frequent, have impact on the normal of railway
Operation.2nd, existing ocs isolating switch monitoring system control command single-unit point mode, either actual control command is also
It is external interference signal, ocs isolating switch can all acts, malfunction, poor anti jamming capability, poor reliability easily occurs.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ocs isolating switch monitoring system, solves to miss
The problems such as dynamic, tripping, make system more reliable and more stable.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of ocs isolating switch monitoring system, separates in monitoring RTU：RTU working powers are with control power supply indirectly
Having air switch 1QF1, control power supply is connected to air switch 1QF2 to mechanism case is separated；RTU controllers are connected with transmission channel,
The RTU controllers are connected to remote control combination switch HA, remote control switch-dividing TA to mechanism case is separated；
Separate in mechanism case：Disconnecting switch motor, the working power of disconnecting switch are connected with air switch 1QF2 respectively, plus
Thermoelectric generator is connected with air switch 2QF2；Described air switch 1QF2,2QF2 are parallel to air switch 1QF2；The air switch
1QF2 is provided with motor-operating mechanism CM；The motor-operating mechanism CM with separate remote control combination switch HA, remote control point in monitoring RTU
Switch TA connections.
Further, separate RTU controllers in monitoring RTU to be connected with transmission channel, RTU controllers are to separating operating mechanism
Disconnecting switch sets remote control separating brake switch Kc1, Kc2, remote control closing switch Ko1, Ko2 in case；Remote control closing switch Ko2, remote control
Separating brake switch Kc2 one end is respectively connected to disconnecting switch, and the other end is respectively connected to RTU controllers；Remote control closing switch Ko1, remote control
Separating brake switch Kc1 one end is coupled to disconnecting switch, and the other end is respectively connected to RTU controllers.
Compared with prior art, the beneficial effects of the utility model are：
1st, ocs isolating switch electric motor loop and performance loop share an air switch, and air switch is included far
Dynamic control.When only carrying out divide-shut brake control operation to ocs isolating switch, disconnecting switch electric motor loop and performance loop are
There is electricity, do not operate not to electricity.The ocs isolating switch tripping that causes and control loop are because of interference after avoiding air switch from tripping
Signal connects the ocs isolating switch malfunction that electric motor loop causes.
2nd, ocs isolating switch divide-shut brake control command is realized using binode control loop.Two separating brakes or two conjunctions
Effectively, ocs isolating switch can just perform divide-shut brake control command to lock control signal simultaneously；Even if having a control signal has
Effect, ocs isolating switch will not also be acted, and greatly reduce the malfunction probability that interference signal is caused.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model disconnecting switch and RTU power supply wirings and air switch set as shown in Figure 4.Ocs isolating switch is heated
Loop, RTU are respectively provided with air switch.Disconnecting switch electric motor loop and performance loop are shared into an air switch 2QF1, and
Air switch is included into remote control.When carrying out breaking-closing operating to ocs isolating switch, air switch 2QF1 is first closed,
Operated again, after the completion of operation, closed air switch 2QF1.So, ability is to electric motor loop when operating ocs isolating switch
It is powered with control loop, does not operate and do not power.After avoiding air switch from tripping the ocs isolating switch tripping that causes and
Control loop connects the ocs isolating switch malfunction that electric motor loop causes because of interference signal.
The utility model RTU to the remote control separating brake of disconnecting switch, remote control shutting-brake control order be to be controlled back by binode
What road was realized, as shown in Figure 5.When carrying out long-range separating brake to ocs isolating switch, control signal Kc1, Kc2 must be all effective,
Ocs isolating switch can just perform separating brake order.When carrying out remote switching to ocs isolating switch, control signal Ko1, Ko2
Must all effectively, ocs isolating switch can just perform combined floodgate order.This kind of mode, greatly reduces the mistake that interference signal is caused
Dynamic probability.
Ocs isolating switch electric motor loop and performance loop share an air switch, and air switch is included into telemechanical
Control.This air switch must be first closed, breaking-closing operating could be carried out to ocs isolating switch.Ocs isolating switch point
Shutting-brake control order is realized using binode control loop.Two separating brakes or two energization control signals are simultaneously effective, contact net
Disconnecting switch can just perform divide-shut brake control command.
Ocs isolating switch far controls the control of control command binode, can also use Fig. 6 using the method shown in Fig. 5
Shown method：Ko1, Kc1 same point K will be merged into Fig. 5.When carrying out long-range divide-shut brake to ocs isolating switch,
Control signal K is first issued, then issues long-range divide-shut brake control signal.This kind of mode, it is identical with Fig. 5 effects, reduce interference letter
Number malfunction probability for causing.
