Abstract
The utility model discloses a power distribution cabinet temperature regulating device, which is arranged on a power distribution cabinet and comprises a temperature regulator and a temperature probe connected with the temperature regulator. The temperature regulator is connected with an intermediate relay which is connected with a fan embedded in a front gate of the power distribution cabinet. The temperature regulating device controls temperature range inside the power distribution cabinet by presetting an upper temperature limit and a lower temperature limit of the temperature regulator. When temperature inside the cabinet exceeds the upper limit value, the temperature probe transmits signals to the temperature regulator which then acts, then the intermediate relay is released, and a power source supplies power to the fan through a pair of normally closed contacts of the intermediate relay so that the fan operates to lower the temperature inside the cabinet. When the temperature inside the cabinet is lower than the preset lower limit value, the temperature probe transmits signals to the temperature regulator which then act, accordingly the intermediate relay is closed, the power source stops power supply, and the fan stops running. Use of the temperature regulating device improves reliability of power supply and reduces breakdown.
Description
Technical field
The utility model belongs to power equipment safety operation auxiliary body technical field, particularly a kind of power distribution cabinet temperature regulating device.
Background technology
Early stage power distribution cabinet is because reasonable inadequately in the design, some power distribution cabinets window that do not dispel the heat, though but some has the perforate of heat radiation window too small, when summer high temperature, because rapidly increasing progressively of outdoor temperature rising and masses' productive life power load, the temperature of switchgear house are easy to reach degree more than 70, the temperature of part electrical equipment may be taller, this just may jump plastics air circuit heat and burn out, and has had a strong impact on power supply reliability.The power distribution cabinet that operating temperature is high dispels the heat the equipment breakdown that electric elements and joint long-play easily cause short circuit or burn power distribution cabinet as if untimely passing through when the summer high temperature high load capacity.The a few thing personnel are arranged when summer high temperature, door before and after the power distribution cabinet is opened the natural draft cooling, increased unsafe factor but do like this.
The utility model content
The utility model provides a kind of can guarantee the power distribution cabinet temperature regulating device of distribution in-cabinet temperature in a normal range (NR).
A kind of power distribution cabinet temperature regulating device, be arranged on the power distribution cabinet, comprise a temperature controller and a temperature-sensing probe that is connected with described temperature controller, described temperature controller connects an auxiliary relay, and described auxiliary relay connects a blower fan that is embedded in the power distribution cabinet Qianmen.
The utility model is by the bound temperature of default temperature controller, control the temperature range in the power distribution cabinet, when in-cabinet temperature surpasses higher limit, temperature-sensing probe is passed to the temperature controller signal, the temperature controller action, auxiliary relay discharges, and power supply is by a pair of normally closed contact fan power supply of auxiliary relay, fan operation reduces the temperature in the cabinet.When in-cabinet temperature was lower than the lower limit of setting, temperature-sensing probe was passed to the temperature controller signal, the temperature controller action, and the auxiliary relay adhesive, power supply is stopped power supply, and blower fan is out of service.Use of the present utility model has improved the reliability of power supply, has reduced the generation of fault.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of power distribution cabinet temperature regulating device, be arranged on the power distribution cabinet 1, comprise a temperature controller 2 and a temperature-sensing probe 3 that is connected with described temperature controller 2, described temperature controller 2 connects an auxiliary relay 4, and described auxiliary relay 4 connects a blower fan 5 that is embedded in power distribution cabinet 1 Qianmen.
The utility model is by the bound temperature of default temperature controller, control the temperature range in the power distribution cabinet, when in-cabinet temperature surpasses higher limit, temperature-sensing probe is passed to the temperature controller signal, the temperature controller action, auxiliary relay discharges, and power supply is by a pair of normally closed contact fan power supply of auxiliary relay, fan operation reduces the temperature in the cabinet.When in-cabinet temperature was lower than the lower limit of setting, temperature-sensing probe was passed to the temperature controller signal, the temperature controller action, and the auxiliary relay adhesive, power supply is stopped power supply, and blower fan is out of service.Use of the present utility model has improved the reliability of power supply, has reduced the generation of fault.
