Abstract
The utility model discloses a substation fire pool allowing water supplementation through intelligent monitoring. The substation fire pool comprises a pool body, a water level collecting device, an automatic water supplementing device and a programmable logic controller (PLC) control device. The PLC control device is connected with a substation monitoring center. The water level collecting device comprises a water level sensor, and the automatic water supplementing device comprises a control valve arranged on a pool water inlet pipe. Pool inner water level is monitored through the water level sensor, and water level information is sent to the PLC control device. When the pool inner water level is dropped to the position below the critical low water level, the control valve on the water inlet pipe is opened, and water is supplemented to the fire pool timely. When the water level rises to the position above the critical high water level, the control valve is closed, and water supplementing is stopped. The substation fire pool adapts to new trend of intelligent substation development, and implementation of a management mode of unattended substations is quickened.

The beneficial effects of the utility model are: the transformer station's fire cistern that the utility model discloses a kind of intelligent monitoring moisturizing, monitor water level in pond by level sensor, and water level information is sent to PLC control device, below water level in pond drops to critical low water stage time, control valve on water inlet pipe is opened, in time to fire cistern moisturizing, when water level rises to after critical high water level, control valve is closed, and stops moisturizing.PLC control device is connected in the upper managing computer at supervisory control of substation center, make the administrative staff can be at the water level information of supervisory control of substation center monitors fire cistern, when water level generation abnormal conditions, if fire cistern is can not automatic water supplement time, upper managing computer can be by short message alarm module by abnormal conditions Reports Administration personnel, administrative staff can be taken measures in time, fix a breakdown, guarantee that fire cistern has enough water supply volumes.Transformer station's fire cistern of intelligent monitoring moisturizing of the present utility model adapts to the new trend of intelligent substation development, accelerates to put into practice the management mode of unattended substation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is the structural representation of embodiment mono-of the present utility model;
Fig. 2 is the structural representation of embodiment bis-of the present utility model.
The specific embodiment
embodiment mono-
With reference to Fig. 1, a kind of transformer station's fire cistern of intelligent monitoring moisturizing, comprises pond 5, water level acquisition device, automatic water-replenishing device, PLC control device 1, and described PLC control device 1 is connected with supervisory control of substation center 3.
Described water level acquisition device comprises level sensor, described level sensor adopts throw-in type water level transmitter 4, described throw-in type water level transmitter 4 is fixedly mounted on to the bottom in pond 5, this throw-in type water level transmitter 4 can continuous measurement transmitter to the height of water level of the water surface, described throw-in type water level transmitter 4 is connected with PLC control device 1, measured waterlevel data is transferred to PLC control device 1, PLC control device 1 compares the level measuring data of obtaining and the water level threshold that prestores, carries out decision-making to whether carrying out moisturizing to transformer station's fire cistern 5.
Described automatic water-replenishing device comprises the control valve 2 being arranged on the water inlet pipe of pond, and the coil block of described control valve 2 is connected with the output of PLC control device 1.When the level measuring data of obtaining when PLC control device 1 are less than low water stage threshold, PLC control device 1 outputs level signals, to the coil block of control valve 2, starts control valve 2, and water inlet pipe starts to pond 5 moisturizings; In the time that level measuring data are greater than high water level threshold, PLC control device 1 disconnects level signal, and control valve 2 is closed, and stops moisturizing.
Described supervisory control of substation center 3 comprises upper managing computer 31, and described upper managing computer 31 is connected with PLC control device 1 by RS485 or RS232 bus connecting mode or RJ45 network interface or LAN wireless network.By upper managing computer 31, administrative staff can be at the water level information of supervisory control of substation center 3 Real-Time Monitoring fire cisterns.
