Abstract
The utility model discloses a novel ring network cabinet with moistureproof and heating functions, which belongs to the field of an electric power technology. The novel ring network cabinet with moistureproof and heating functions comprises a ring network cabinet body and a casing; a temperature sensor, a humidity sensor, a humiture controller, a heater and a fan are arranged in the casing; the heater is arranged on the side plate of the casing; the fan is arranged on the back panel of the casing; the signal output terminals of the temperature and humidity sensors are connected with the humiture controller; the humiture controller is connected with the heater and the fan; and the humiture controller receives the signal data detected by the temperature and humidity sensors and controls the heater and the fan to work. According to the novel ring network cabinet, the structure is simple, usage is convenient, a moistureproof effect is good, the temperature sensor and humidity sensor are arranged in the casing of the ring network cabinet to feed back the temperature and humidity in the casing to the humiture controller, the humiture controller receives corresponding information and compares the received information to preset temperature and humidity values, thereby the heater and the fan are controlled, heat generated by the heat is transformed to heat wind by the fan, moisture generated in the casing is blown away, the interior of the casing is always maintained to be dry, thereby condensation is prevented, and the power supply reliability is guaranteed.
Description
Technical field
The utility model belongs to electric system ring main unit technical field, especially relates to a kind of electric power ring main unit that possesses protection against the tide, heating function.
Background technology
Ring main unit is the visual plant in the electric system, and the metalwork surface forms condensation easily in the cabinet that is in operation, thereby causes ring main unit phase fault or other accident, the safe operation of serious threat electrical network.The factor that forms condensation mainly contains: (1) area surroundings temperature height, temperature Change is big, during hot cold air exchange easily at the metal surface condensation; (2) ring main unit bottom is moist, even in the cable duct that has ponding is arranged, and during water evaporation, when being lower than in the cabinet air themperature as metallic surface temperature, forms condensation in the metal surface; (3) equipment that has is in shut down condition, and in-cabinet temperature is lower than environment temperature, causes that the metal surface has the globule to condense.
At above-mentioned phenomenon, usually the prevention treatment measures of certain heating and dehumidification in ring main unit, have been adopted, but in use in some high humidity areas problem has appearred still, therefore improve the whole condensation control ability in the looped network cabinet, the safe operation ability that improves whole electrical network is those skilled in the art's urgent problems.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of simple in structure, easy to use, electric power ring main unit of possessing protection against the tide, heating function.
The utility model is to adopt following technical scheme to realize: a kind of novel ring main unit, comprise the ring main unit body, casing, box house is equipped with temperature sensor, humidity sensor, temperature and humidity controller, well heater and fan, well heater is installed on the side plate of casing, fan is installed on the cabinet rear panel, temperature, the signal output part of humidity sensor is connected with temperature and humidity controller, temperature and humidity controller is connected with fan with well heater, temperature and humidity controller receives temperature, the signal data that humidity sensor detects, and control heater and fan work, temperature and humidity controller arranges the RS485 communication interface.
Compared with prior art, the utility model is simple in structure, easy to use, dehumidifying is effective, by in the ring main unit casing, temperature sensor being installed, humidity sensor, so that real-time temperature in temperature and humidity controller feedback casing, the humidity situation, after temperature and humidity controller receives corresponding information, with default temperature, humidity is compared, thus control heater and fan work, and fan converts the heat that well heater produces to hot blast, with the moisture hot blast drying that produces in the casing, remain the case inner drying, thereby prevented condensation, guaranteed the reliability of power supply.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model structured flowchart;
Among the figure: the 1-casing; The 2-body; The 3-RS485 communication interface; The 4-temperature and humidity controller; The 5-fan; The 6-well heater.
Embodiment
As shown in Figure 1, this novel ring main unit comprises ring main unit body 2, casing 1, box house is equipped with temperature sensor, humidity sensor, temperature and humidity controller 4, well heater 6 and fan 5, temperature and humidity controller 4 arranges RS485 communication interface 3, well heater 6 is installed on the side plate of casing 1, fan 5 is installed on casing 1 rear panel, temperature sensor, the signal output part of humidity sensor is connected with temperature and humidity controller 4, temperature and humidity controller 4 is connected with fan 5 with well heater 6, temperature and humidity controller 4 receives temperature sensor, the signal data that humidity sensor detects, and control heater 6 and fan 5 work, carry out telecommunication and monitoring by RS485 communication interface 3.
When casing 1 interior environment temperature, when humidity reaches the setting value of temperature sensor, humidity sensor, temperature and humidity controller 4 starts well heater 6 and fan 5 operations automatically, fan 5 converts the heat that well heater 6 produces to hot blast, the moisture that produces in the casing 1 is dried up, to improve casing 1 interior environment temperature; After temperature, humidity were lower than setting value in the casing 1, well heater 6 and fan 5 outage automatically stopped.
Claims (2)
1. novel ring main unit, it is characterized in that: it comprises that ring main unit body, casing, box house are equipped with temperature sensor, humidity sensor, temperature and humidity controller, well heater and fan, well heater is installed on the side plate of casing, fan is installed on the cabinet rear panel, the signal output part of temperature, humidity sensor is connected with temperature and humidity controller, temperature and humidity controller is connected with fan with well heater, and temperature and humidity controller receives signal data control heater and the fan work of temperature, humidity sensor detection.
2. novel ring main unit according to claim 1 is characterized in that, described temperature and humidity controller band RS485 communication interface.
