Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The technical solution of the utility model is applied to the sub-district distribution system with automatic control technology, and its distribution system is formed and comprised box-type substation, subscriber unit and supervising device, and supervising device is connected with box-type substation, and it is monitored.For the distribution system with many box-type substations, each box-type substation is connected with electrical network by user's switching device shifter.In this system, supervising device not only is connected with all box-type substations, also will be connected with user's switching device shifter, and user's switching device shifter is implemented monitoring.
Embodiment
As shown in Figure 1.Outdoor switching station (or cable branch box) is used to connect 12KV power voltage supply circuit and two above box-type substations, be have cut-off, the switchgear assembly (cable branch box has only linkage function) of metering and route protection function.Have only a box-type substation as the sub-district, need not select this equipment for use, box-type substation can directly be connected with 12KV voltage transmission line.And after selecting this equipment for use, this equipment can be directly to the transformer supplying power for input end of box-type substation.
Box-type substation, function be will input 12KV voltage, become 0.4KV voltage after, multi-line output offers subscriber unit.
Subscriber unit comprises: distributed board outdoor, be connected with the box type transformer outlet line, and control outdoor power consumption equipment nearby; Metering distribution box in unit is connected the usefulness of control unit metering with the box type transformer outlet line; The family distribution box, control family electrical installation.
Supervising device is selected digital supervising device here for use.The supervising device structure as shown in Figure 2, its composition comprises testing circuit, A/D converter, actuator, controller and communication interface.Testing circuit detects the relevant parameter of box-type substation, outdoor switching station respectively, and testing result becomes the digital signal input controller through A/D converter.Controller is according to above-mentioned parameter, handles the output control signal by internal processes, drive actuator to the open air switching in one's power box-type substation control.Detect data and also can transmit by communication interface, controller also can receive the instruction of communication network transmission equipment is controlled.
Supervising device is in order to the operating state of supervisory user switching device shifter and box-type substation turnover wiretap, data such as electric current, voltage, meritorious, idle, power factor (PF), busbar temperature, temperature of oil in transformer are provided in real time, automatic control compensation electric capacity switching cycle, and write down every group of electric capacity accumulative total switching time etc., also monitoring range can be extended to subscriber unit.All data all can be sent to strange land computer, mobile phone by wired or wireless mode, also can send instruction to system by strange land computer, mobile phone.The built-in looped network control logic of supervising device can realize many power supplys looped network function.Prized at system equipment Operation and Maintenance door, or when accident phenomenons such as pyrotechnics acousto-optic occurring, can in time report to the police, the equipment total system need not staff on duty.
