The second parallel branch connect；Power-off green light L1 installed in maintenance storehouse scene, the power-off green light L2 phases installed in the class of group room
After mutual parallel connection, then with auxiliary reclay KA1 normally-closed contact and installed in the normally closed of the live dangerous prompting button AN in maintenance storehouse
The 3rd parallel branch that contact concatenation forms；Auxiliary reclay KA1 normally-closed contact, dangerous the reminding installed in maintenance storehouse scene
The 4th parallel branch that button AN normally opened contact and the warning amber light V1 live installed in maintenance storehouse are mutually concatenated.
During work, when parking lot or the rolling stock section affiliated disconnecting switch auxiliary contact Gn of maintenance storehouse contact net disconnect, station track
Overlying contact net is in off-position, and now, the first parallel branch is off-state, and auxiliary reclay KA1 is not charged, and its is normally opened
Contact disconnects, normally-closed contact closure, and the second parallel branch is off-state, and the 3rd parallel branch is on-state, installed in inspection
Power-off green light L1, the L2 for repairing storehouse scene and the class of group room are bright；When field personnel has found that danger need to notify that operating personnel withdraws,
The dangerous prompting button AN of installation at the scene can be pressed, disconnects its normally-closed contact, normally opened contact closure, it is yellow so as to trigger warning
Lamp V1 is bright.When parking lot or the rolling stock section affiliated disconnecting switch auxiliary contact Gn of maintenance storehouse contact net are closed, station track overlying contact
Net is in electriferous state lamp, and now, the first parallel branch is on-state, and auxiliary reclay KA1 is powered, and its normally opened contact closes
Close, normally-closed contact disconnection, the second parallel branch is on-state, and the 3rd parallel branch is off-state, is showed installed in maintenance storehouse
Powered red light H1, H2 of field and the class of group room are bright, and trigger the audible-visual annunciator Q alarms at installation and repairing storehouse scene.
Further, in addition to by auxiliary reclay KA1 normally opened contact concatenated with inspection platform end door electronic lock S and
Into the 5th parallel branch.For the station track with stereo maintenance platform：When station track overlying contact net is in electriferous state（Connect
Disconnecting switch auxiliary contact Gn belonging to net-fault is closed, and auxiliary reclay KA1 is powered, and the 5th parallel branch is connected）, also can trigger inspection
Electronic lock obtains electric at equating you door, end door is in locking state, can effectively prevent personnel from swarming into powered inspection platform.
The utility model is reasonable in design, novel, unique, and installation is simple, and easy to operation, implementation is strong, to parking lot
Or whether rolling stock section's corresponding station track overlying contact net in maintenance garage is powered plays monitoring and reminding effect, and to three-dimensional in maintenance storehouse
The end door of job platform top layer platform two is controlled（During contact net electrification end door can not be opened on the outside of end door）, it is train overhaul
The safety of personnel provides safeguard；Each station track contact net state of multiple display screen curtain simultaneous display is set in the class of group room simultaneously, to custodian
Member provides easily supervising platform.Each equipment belonging to the utility model or each part can be according in rolling stock sections or parking lot maintenance storehouse
Overhaul stock scale, length-flexible is equipped with.
Brief description of the drawings
Fig. 1 is the schematic diagram of monitoring circuit described in the utility model（Without the 5th parallel branch）；
Fig. 2 is the schematic diagram of monitoring circuit described in the utility model（With the 5th parallel branch）；
Fig. 3 is the schematic diagram of warning circuit in warning box described in the utility model.
Embodiment
Contact net electrification state monitoring apparatus, including monitoring circuit, described monitoring circuit include, by parking lot or vehicle
The first parallel branch that the section maintenance affiliated disconnecting switch auxiliary contact Gn of storehouse contact net concatenates with auxiliary reclay KA1；Peace
