Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model：
Fig. 1 is cable tunnel monitoring system structural representation.
Embodiment
The utility model is further explained below in conjunction with specific embodiment, but does not limit to this practicality
It is new.
As shown in figure 1, technical solutions of the utility model include transformer station A1, transformer station B2, box-like power distribution station A3, box matched somebody with somebody
Power station B4, tunnel low-voltage lighting distribution box and illuminator, described transformer station A1 are the box-like power distribution station A3 power supply sources stated,
Power supply is assigned to tunnel low-voltage lighting distribution box 5 after box-like power distribution station A3 transformations；Described transformer station B2 box matches somebody with somebody to be described
Power station B4 provides power supply, and power supply is equally assigned to low-voltage lighting distribution box 5 in tunnel after box-like power distribution station B4 transformations, described
Low-voltage lighting distribution box 5 is that the illuminator 10 provides mains lighting supply, i.e. box-like power distribution station A3 and box-like power distribution station in tunnel
B4 is that the two-way of the tunnel low-voltage lighting distribution box 5 dispenses power supply.Dual power supply is provided with described low-voltage lighting distribution box 5
Automatic switching control equipment 6 and voltage transformer 7, described dual power supply automatic switching device 6 are provided with automatic change-over 8 and control
Device 9；Voltage transformer 7 is used to detect whether two-way dispatching power supply has voltage, and by the information transmission of detection to controller 9, control
Device 9 processed control automatic change-over 8 carry out two-way power supply access or disconnection switching, specifically how to switch see it is following old
State.
Transformer station A1 described here and transformer station B2 is 66kV transformer stations, and the box-like power distribution station A3 matches somebody with somebody with box
Power station B4 is 10kV transformer stations.Box-like power distribution station A3 10kV power supplys come from 66kV transformer stations A1, box-like power distribution station B4's
10kV power supplys come from 66kV transformer stations B2, i.e., power supply is delivered to box-like power distribution station A3 by described transformer station A1 by 10kV circuits；
