The accompanying drawing explanation
Fig. 1 is the schematic block diagram of the utility model intelligence PT cabinet integrated system.
In above-mentioned accompanying drawing, 1, power module; 2, user demarcation on-off controller module; 3, PT module; 4, ring main unit; 5, DTU module.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the intelligent PT cabinet integrated system that the utility model provides, comprise power module 1, user demarcation on-off controller module 2, DTU module 5, PT module 3 and ring main unit 4; Power module 1 connects respectively user demarcation on-off controller module 2, DTU module 5 and ring main unit 4; User demarcation on-off controller module 2 is connected with PT module 3 with ring main unit 4 respectively; DTU module 5 is connected with ring main unit module 4.
Power module 1 comprises supply line and sampling circuit; From the power supply PT(FJDZR1-10G of the high-tension electricity on high voltage bus (being the 10kv high-tension electricity in the present embodiment) through power module 1, no-load voltage ratio 10kV/0.22kV) after transformation, one tunnel is walked sampling circuit and is provided voltage sampling signal for user demarcation on-off controller module, and another road provides working power for user demarcation on-off controller module, DTU module and ring main unit after via supply line's transformation.Wherein, the working power voltage of the control module of user demarcation on-off controller module and DTU is direct current 48V, and the communication module of DTU is direct current 24V.Power module 1 also comprises the stand-by power supply be connected with supply line.Stand-by power supply is in series by the more piece storage battery, can discharge and recharge operation, the power consumption of 8 of the system modules hours in the time of can guaranteeing power supply trouble.
User demarcation on-off controller module 2 is connected with the ring main unit outgoing, and controller secondary connection content wherein is to be connected with ring main unit outgoing breaking coil with the CT of ring main unit outgoing, PT in the PT module.User demarcation on-off controller module is by the detection to looped network outgoing, PT, and tripping operation is controlled to the ring main unit outgoing.After in user circle, single phase ground fault occurring, directly start this loop load switch of electromagnetic trip tripping, after phase fault occurs, at transformer station's feeder breaker separating brake, after the circuit dead electricity, start this loop load switch of electromagnetic trip tripping.Voltage sampling signal detection line voltage and the line current of when house dog controller judgement dead electricity with no pressure is jumped, utilizing simultaneously sampling circuit to provide.
