Description
Technical field
The utility model relates to the remote monitoring and the control of substation equipment, especially the anti-condensation supervising device of transformer station's terminal box.
Background technology
Transformer station's terminal box is outdoor electrical equipment and the intermediate link that equipment such as indoor observing and controlling, protection, communication are connected, and generally is installed in by the relevant device on the spot.When there was dampness in the air, especially in rainy season, the moist meeting of outdoor switch terminal box internal cause condensation ponding was prone to cause the insulation against ground resistance value of direct current secondary circuit to descend, and the severe patient insulating resistance value can drop to zero, thereby forms dc positive power or negative supply ground connection.If cause 2 ground connection of direct current, then can cause dc insurance fusing, protection tripping or malfunction, even damage equipment, the safe operation of serious threat electrical network.In addition, making moist in the terminal box also makes terminal row screw and brace get rusty, and makes the loose contact of secondary terminal, can make current transformer terminal heating even open circuit too, causes protection tripping or malfunction, causes accident.
At present the condensation-preventing controller that adopts of transformer station's terminal box all is direct control model, can not Long-distance Control with parameter is set.The transformer station of diverse location environment of living in is different; Environment in the terminal box is just different, and the installation place of condensation-preventing controller is also different in the case, the comparison that has near case at the bottom of; What have pushes up near case; So just might cause that the data that the Temperature Humidity Sensor in the same case collects are different, particularly rain or winter the time, difference is more obvious.If the actual geographic position according to transformer station, weather conditions that can not be real-time be adjusted the parameter of controller, will cause many times controlling not in place, it is bad not play anti-condensation effect or effect.Under a lot of situation, whether the temperature and humidity controller in the terminal box works must the staff of transformer station be gone site inspection, time-consuming effort again.
The utility model content
The purpose of the utility model provides a kind ofly can carry out this locality and far-end is adjusted in good time according to environmental change, reduces the anti-condensation supervising device of transformer station's terminal box that fault takes place.
For this reason; Transformer station's terminal box of the utility model is prevented the condensation supervising device; Include microcontroller and the power module that links to each other with microcontroller, remote-transmission module, fan, heating piece and Temperature Humidity Sensor; Temperature Humidity Sensor has two humitures that are used for gathering the terminal box internal and external environment respectively; Form two groups of humiture data information transfer and give microcontroller, microcontroller carries out analysis and judgement to two groups of humiture data messages, sends work order information to fan and heating piece; Simultaneously microcontroller sends to staff's remote controller with the work state information of two groups of humiture data messages and fan and heating piece through remote-transmission module, and microcontroller can be accepted the instruction that remote controller sends intervention is forced in the fan and the work of heating piece.
The environment difference that the transformer station of diverse geographic location is of living in; The internal and external environment of terminal box will be different, and also frequent different in the installation place of condensation-preventing controller in the terminal box, the comparison that has near case at the bottom of; What have pushes up near case; So just might cause that the data that the Temperature Humidity Sensor in the same terminal box collects are different, particularly rain or winter the time, difference is more obvious.
Power module is used for converting alternating voltage into DC voltage to the each several part circuit supply in the utility model.Microcontroller is used to control each several part circuit operate as normal.The heating piece is used for heating, drives tide to terminal box.Fan is used for terminal box is dehumidified.Two Temperature Humidity Sensors are used to gather the inside and outside humiture data of terminal box.Remote-transmission module is used for the humiture data in Long-distance Control and the remote collection terminal box.Power supply is supplied with and is the 220V civil power, adopts switching power supply that system's power supply is provided.After powering on; Microcontroller is started working, and microcontroller is the interior data of sensing with the outer temperature and humidity controller of case of vasculum at first, then two groups of data are compared; Judge whether this unlatching heating piece and fan, be transferred to remote controller through remote-transmission module then.Actual conditions and the current actual humiture situation of staff when installing originally controlled fan and heating piece, and the time span of unlatching is set.The time interval of teletransmission equally can be through long-range setting.Staff's Long-distance Control priority is higher than the built-in controlling mechanism of microcontroller.
The utility model can effectively improve the unfavorable condition in the terminal box, prolongs the service time of terminal box equipment, reduces because the generation of the accident that environmental impact causes has improved staff's work efficiency.
