Description

Transformer station's Outdoor Terminal Case automatic switching firing equipment

Technical field

The utility model relates to a kind of transformer station outdoor equipment, and particularly the automatic switching firing equipment of terminal box in time heats to change its inner humiture terminal box.

Background technology

The Outdoor Terminal Case of transformer station is a kind of interface arrangement of providing convenience for isolating switch, voltage transformer (VT), transformer, the terminal switching of metering secondary line, wiring and the line inspection.The casing of the Outdoor Terminal Case of transformer station mostly adopts common metal foil to make, and heat-insulation and heat-preservation property is poor, every rainy season, winter or driving rain weather, and box equipment very easily makes moist and condensation.When the temperature inside the box is too high, each components and parts easy ageing in the case; When humidity is excessive in the case, can cause the insulation breakdown of the mould disconnected and operating mechanism of casing corrosion, coil, connecting terminal block etc., have a strong impact on the normal operation of equipment.

Summary of the invention

The purpose of the utility model is for overcoming the deficiency of prior art, providing a kind of and can make the automatic switching firing equipment that remains freeze-day with constant temperature in the terminal box.

The technical scheme that the utility model adopts is: comprise temperature, humidity collecting unit, electronic heating arrangement, wireless transmitter and CPU; Temperature collecting cell is made up of external temperature collecting unit and internal temperature collecting unit; The humidity collecting unit is made up of outside humidity collecting unit and interior humidity collecting unit, and internal temperature collecting unit, interior humidity collecting unit, electronic heating arrangement, wireless transmitter module are arranged on the inside of terminal box; External temperature collecting unit, outside humidity collecting unit, wireless receiving module and CPU are arranged on the outside of terminal box; CPU connects LED display, electronic heating arrangement, external temperature collecting unit, outside humidity collecting unit and wireless receiving module respectively through different ports; LED display is arranged on the outside surface of terminal box.

The utility model is integrated, and humiture detection and electric energy add heating integrated control technology; Automatically accomplish terminal box inside and outside humiture collection and contrast; At any time monitor the inside and outside temperature and humidity situation of change of terminal box; Accurately judge the humiture variation and add heating arrangement automatically, thereby eliminated the potential safety hazard that causes the Outdoor Terminal Case accident because of humiture in the case unusually, can be uploaded to data center with detecting data wireless automatically simultaneously; The staff also can accomplish humiture inquiry in the case through man-machine interface, and the humiture early warning value is set; Simple in structure, easy to operate.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural drawing of the utility model.

Among the figure: the 1.LED display screen; 2. terminal box; 3. internal temperature collecting unit; 4. interior humidity collecting unit; 5. electronic heating arrangement; 6. wireless transmitter module; 7. outside humidity collecting unit; 8. wireless receiving module; 9.CPU; 10. external temperature collecting unit.

Embodiment

Referring to Fig. 1, the automatic switching firing equipment of the utility model comprises temperature collecting cell, humidity collecting unit, electronic heating arrangement, wireless transmitter and CPU.Wherein, temperature collecting cell is made up of external temperature collecting unit 10 and internal temperature collecting unit 3, temperature collecting cell employing temperature sensors of high precision, and temperature-measuring range is-40-125 ℃.The humidity collecting unit is made up of with interior humidity collecting unit 4 outside humidity collecting unit 7, and the humidity collecting unit adopts the high precision humidity sensor, and measurement range is 0-100%.Internal temperature collecting unit 3, interior humidity collecting unit 4, electronic heating arrangement 5, wireless transmitter module 6 are arranged on the inside of terminal box 2.External temperature collecting unit 10, outside humidity collecting unit 7, wireless receiving module 8 and CPU9 are arranged on the outside of terminal box 2.LED display 1 is installed on the outside surface of terminal box 2.CPU9 connects LED display 1, electronic heating arrangement 5, external temperature collecting unit 10, outside humidity collecting unit 7 and wireless receiving module 8 respectively through different ports.

Internal temperature collecting unit 3, interior humidity collecting unit 4 all connect wireless transmitter module 6; Internal temperature collecting unit 3, interior humidity collecting unit 4 are gathered the temperature and humidity in the terminal box 2 respectively; Temperature, the humidity actual numerical value of gathering are launched through wireless transmitter module 6, the internal temperature, the humidity that receive are input among the CPU9 at terminal box 2 outside wireless receiving modules 8.Simultaneously, terminal box 2 outside external temperature collecting units 10 also are input to external temperature, the humidity of gathering among the CPU9 with outside humidity collecting unit 7.The communication coverage of wireless transmitter module 6 and wireless receiving module 8 is a 300-500 rice, is operated in the 470MHz frequency range.

CPU9 compares the temperature and humidity numerical value of 2 inside and outside of terminal boxs; When terminal box 2 interior environment temperature are lower than preset temperature or have condensation to produce; CPU9 controls electronic heating arrangement 5, starts electronic heating arrangement 5 operations and heating automatically, to improve the environment temperature of terminal box 2 inside; Reduce the humidity in the terminal box 2 simultaneously, destroy the environment that produces condensation.When the condition that produces condensation in the terminal box 2 disappears or environment temperature when reaching preset temperature, electronic heating arrangement 5 heating of CPU9 automatic cutout, CPU9 returns to monitoring state again.The duty of the temperature of terminal box 2 inside and outsides, the actual numerical value of humidity and electronic heating arrangement 5 shows by LED display 1.
