A large number of live box bodies such as outdoor terminal boxes, power boxes, control cubicles, junction boxes, mechanism boxes and the like are arranged in the transformer substation, and the function of connecting outdoor electrical equipment with indoor measurement and control, protection, communication and other equipment is achieved; the transformer substation has a large number of electrified screen cabinets for protection, control, automation, communication, alternating current and direct current power supplies and the like indoors, and the box bodies and the screen cabinets almost contain all important secondary control protection equipment, so that the transformer substation is safe to operate.
Outdoor equipment of a transformer substation is greatly influenced by environmental conditions, and the temperature difference between the inside and the outside of the equipment is too large after thunderstorms in summer or sudden temperature drop in autumn and winter. The inner wall, the top and the terminal row of the equipment box body are always subjected to condensation, and if the condensation is serious, direct current grounding or terminal short circuit can be caused, so that protection misoperation or operation failure is caused. When rainstorm or rain cover leakage occurs, water may be accumulated at the bottom of the cabinet body. In addition, if these box screen cabinets are abnormal because of external environment or internal ventilation and damp-removing equipment, internal equipment is caused to enter water, condense, damp and the like, and then internal device faults are caused. In recent years, accidents such as discharging, corrosion, direct current grounding, misoperation or failure of a protection device and the like frequently occur because effective measures are not taken in time after a box body is condensed or inlet water is damped, and the safe and stable operation of equipment and a power grid is seriously influenced. Therefore, the monitoring and alarming device has important significance in monitoring and alarming the water inflow condensation inside the transformer substation box body.
At present, current transformer substation's box screen cabinet is very few to be designed as key equipment with ventilation damp-dispelling device, and indoor equipment only sets up ventilation thermovent or radiator fan usually, and outdoor equipment often only disposes a simple heater to these simple damp-dispelling devices do not have the fault warning return circuit mostly, and heater, fan trouble can not in time be discovered by the operation personnel, have left very big potential safety hazard. Even if a temperature and humidity alarm or a condensation alarm is installed on part of the box body, the temperature and humidity conditions in the box body can only be reflected, condensation is indirectly judged through temperature and humidity calculation, and condensation and water inlet conditions cannot be accurately reflected.
In addition, the outdoor box often appears because of sealed bad, the material corrosion, cabinet door or cabinet body warp etc. and cause phenomenon such as inside intaking, condensation, and simple heating ventilation unit can not guarantee the good nature of outdoor box internal environment. In the existing unattended management mode of the transformer substation, manual regular box opening inspection is time-consuming and labor-consuming and is difficult to realize. Therefore, it is especially necessary to design a special monitoring and alarming device for the water inflow and condensation inside the transformer substation box body.

the clock chip is connected with the micro control unit processor, the communication module is connected with the micro control unit processor through the communication interface, the communication module sends data collected by the micro control unit processor and judgment results of whether condensation and water immersion exist to the display terminal, and the display terminal gives an alarm according to the judgment results.
Furthermore, the immersion collection module and the condensation collection module adopt immersion ropes.
Further, the temperature and humidity acquisition device further comprises a temperature and humidity module, wherein the temperature and humidity module is arranged in the box body and used for acquiring temperature and humidity data around the environment, and a data output end of the temperature and humidity module is connected with a data input end of the micro control unit processor.
Furthermore, the power supply module is used for providing power for the micro control unit processor, and the power supply module is connected with the micro control unit processor.
The utility model has the advantages that:
the condensation water immersion alarm machine realizes the change from regular manual unpacking inspection to automatic 7 x 24 hour uninterrupted real-time monitoring, ensures the personal safety of operators and greatly improves the working efficiency. The inspection time of the box body is reduced, and if the box body is popularized and used, huge labor expenditure of enterprises can be realized every year. The data support is provided, only the box body which frequently generates condensation water inflow is treated, the treatment without difference is avoided, and the enterprise cost is greatly saved.
The box body condensation water inlet monitoring system can prevent the occurrence of accidents in the bud, and an alarm is given before a condensation water inlet safety line to prompt fault treatment, so that serious faults caused by condensation water inlet are effectively avoided. The patrolman does not need to enter the site to open the box for detection, thus fundamentally avoiding the possibility of accidents.
