Description
Technical field:
The present invention relates to High-Voltage Electrical Appliances convergence control cabinet field, especially a kind of convergence control cabinet automatic temperature-regulator.
Background technology:
At present, shown in accompanying drawing 3, the anti-condensation device of traditional convergence control cabinet can be installed aluminium alloy well heater 3 usually in cabinet, manually drops into or is started by temperature and humidity controller 2, reaches the purpose of moistureproof, anti-condensation.But the air humidity of convergence control cabinet inside is higher sometimes, even local existing dewfall phenomenon in the convergence control cabinet, owing to be installed in the degree that condensation sensor 1 position of cabinet inside does not arrive condensation; Perhaps; Condensation sensor 1 receives dust and gas pickling in the cabinet for a long time, causes the sensitivity of sensor to descend, and temperature and humidity controller can not start well heater 3 in time; Make the inner condensation that produces of convergence control cabinet, bring hidden danger for the safe operation of convergence control cabinet internal electric spare.
Summary of the invention:
The purpose of this invention is to provide a kind of convergence control cabinet automatic temperature-regulator, this device is only controlled the inside and outside temperature difference of convergence control cabinet, promptly reaches the purpose of moistureproof, anti-condensation.The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
A kind of convergence control cabinet automatic temperature-regulator comprises the convergence control cabinet cabinet, and described convergence control cabinet cabinet inner bottom part is provided with well heater; Described well heater connects one and adds thermal control units; It is characterized in that the described thermal control units that adds comprises the in-cabinet temperature sensor that is positioned on the cabinet madial wall, be positioned at the outer temperature sensor of cabinet on the cabinet lateral wall; Be provided with and the external exhaust fan that is communicated with at the cabinet inner top, also be provided with a temperature control modules in the cabinet; The outer temperature sensor of described in-cabinet temperature sensor and cabinet; And exhaust fan and well heater all are electrically connected with temperature control modules; Said in-cabinet temperature sensor in-cabinet temperature is T1; The outer temperature of the outer temperature sensor detecting box of said cabinet is T2, and in-cabinet temperature T1, outer temperature T 2 differences of cabinet are at 3-5 ℃.
The outer temperature sensor of described cabinet is arranged on the outer top of cabinet, and the outer temperature sensor of cabinet is set up mat outward.
Described in-cabinet temperature sensor is arranged on middle part in the cabinet.
The invention has the beneficial effects as follows:
1, this device is only controlled the inside and outside temperature difference of convergence control cabinet, promptly reaches the purpose of moistureproof, anti-condensation, makes the safe operation of convergence control cabinet internal electric spare that guarantee arranged.
2, it is simple in structure, and is easy to implement.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the automatic temperature-regulator electric hookup.
Fig. 3 is the prior art constructions synoptic diagram;
Among the figure: 1, condensation sensor, 2, temperature and humidity controller, 3, well heater, 4, the in-cabinet temperature sensor, 5, temperature control modules, 6, exhaust fan, 7, the outer temperature sensor of cabinet.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the present invention is set forth in detail.
Show after deliberation: under certain temperature condition, relative humidity is high more in the convergence control cabinet, and the temperature of dewfall is near ambient air temperature, and environment temperature is more near dewpoint temperature, and condensation just takes place more easily.But dewpoint temperature is lower than environment temperature all the time.As: when air themperature 25 degree, relative humidity 70%, the temperature of dewfall is 19.1 ℃.Want to prevent the generation of condensation in the convergence control cabinet, must make the surface temperature that produces the condensation position in the cabinet be higher than the outside environment temperature of cabinet all the time.Therefore, the inside and outside temperature difference of control convergence control cabinet can reach purpose moistureproof, that prevent condensation.
Based on above-mentioned research, the specific embodiment of the invention does, like Fig. 1, Fig. 2.
A kind of convergence control cabinet automatic temperature-regulator; Comprise the convergence control cabinet cabinet, described convergence control cabinet cabinet inner bottom part is provided with aluminium alloy well heater 3, and described well heater connects one and adds thermal control units; The described thermal control units that adds comprises the in-cabinet temperature sensor 4 that is positioned on the cabinet madial wall; Be positioned at the outer temperature sensor 7 of cabinet on the cabinet lateral wall, be provided with and the external exhaust fan that is communicated with 6, also be provided with a temperature control modules 5 in the cabinet at the cabinet inner top.
Described in-cabinet temperature sensor 4 and the outer temperature sensor 7 of cabinet; And exhaust fan 6 all is electrically connected with temperature control modules 5 with well heater 3; Like Fig. 2 automatic temperature-regulator electric hookup; In-cabinet temperature sensor 4 is connected 1,2 nodes of temperature control modules 5, and the outer temperature sensor 7 of cabinet is connected 4,5 nodes of temperature control modules 5, and in-cabinet temperature sensor 4 is connected on 3 nodes of temperature control modules 5 with the common terminal of the outer temperature sensor 7 of cabinet; Exhaust fan 6 is connected on 6,9,11 nodes of temperature control modules, and well heater 3 is connected on 6,8,10 nodes of temperature control modules; 6,7 nodes of temperature control modules are connected L end, the N end of AC220V.
