Abstract
The utility model discloses a temperature/humidity monitoring alarm device for a cable trench of an unattended transformer substation. With the temperature/humidity monitoring alarm device of the utility model adopted, the problems existing in temperature/humidity monitoring and alarm of the unattended transformer substation can be solved, The temperature/humidity monitoring alarm device comprises the cable trench of the unattended transformer substation; a temperature sensor (1) and a humidity sensor (2) are arranged inside the cable trench; the temperature sensor (1) and the humidity sensor (2) are electrically connected with a local computer (4) respectively through a serial port circuit module (3); the local computer (4) is connected with a display (5) and a local wireless transmitting and receiving device (6); a remote computer (8) is connected with a remote transmitting and receiving (7); and the local computer (4) is electrically connected with the remote computer (8) through wireless signals. The temperature/humidity monitoring alarm device of the utility model provides a reliable basis for timely acquisition of temperature/humidity change situations inside the cable trench for operation and maintenance departments.
Description
Technical field
The utility model relates to a kind of monitor and alarm system, and particularly a kind of humiture of the cable duct to unattended operation transformer station is carried out the device of monitoring, alarming.
Background technology
In electric system; 220kV and following transformer station have realized unmanned; arrive whenever flood season; conduit line water inlet or moisture are very serious, can only lean on the O﹠M personnel to strengthen the tour dynamics and solve, cable trench water collecting such as untimely discharge; can cause great potential safety hazard to the safe operation of transformer station; on the one hand equipment is made moist, influence insulation and operation stability, ponding too much will corrode the external protection of cable in the cable duct.In case the external insulation layer breakage, the cable live wire contacts with water, can take place single-phase or three-phase earth fault; On the other hand, run into heavy showers weather, the cable duct water level short time goes up too fast, just might not cause ponding to pour in down a chimney the hyperbaric chamber but there is the real-time remote monitoring warning device in the ditch again, draws power grid accident.
Summary of the invention
The utility model provides a kind of unattended operation transformer station cable duct humiture monitoring alarm, has solved the humiture monitoring of cable duct of unattended operation transformer station and the problem of reporting to the police.
The utility model is to solve above technical matters by the following technical programs:
A kind of unattended operation transformer station cable duct humiture monitoring alarm, the cable duct that comprises unattended operation transformer station, in cable duct, be provided with temperature sensor and humidity sensor, temperature sensor and humidity sensor are electrically connected with local computer by the serial port circuit module respectively, be connected with display and local wireless transceiver at local computer, be connected with long-range transceiver at remote computer, local computer and remote computer are electrically connected by wireless signal.
Be connected with audible-visual annunciator at local computer.
The situation of change of humiture provides credible foundation to the utility model in the cable duct for O﹠M department in time grasps, and according to the historical data of humiture on the whole analysis and judgement go out the changing value of different humitures in each unattended operation transformer station cable duct, the regulation and control data of humiture in Various Seasonal issues different regions unmanned substation's cable duct.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of unattended operation transformer station cable duct humiture monitoring alarm, the cable duct that comprises unattended operation transformer station, in cable duct, be provided with temperature sensor 1 and humidity sensor 2, temperature sensor 1 and humidity sensor 2 are electrically connected with local computer 4 by serial port circuit module 3 respectively, be connected with display 5 and local wireless transceiver 6 at local computer 4, be connected with long-range transceiver 7 at remote computer 8, local computer 4 and remote computer 8 are electrically connected by wireless signal.
Be connected with audible-visual annunciator at local computer 4.
Can replace after the utility model is implemented manually regularly checking thermohygrometer, avoid the human error that when manual record humiture data, occurs, save human resources.
