Current distribution box all adopts the non-combustible materials such as steel design to make, though possess certain fire-proof function, but structure is simple, fire-protection rating is lower, and in the occasion such as tunnel and mine, its air humidity is larger, very easily cause electric elements short circuit in casing, and then cause the electric wire in casing, electrical equipment and instrument to be burnt, puncture, and then cause electric power accident, the even condition of a fire.
Distribution box is in operation, its except humidity can not too high except, also have certain requirement to ambient temperature, such as low-voltage electrical apparatus, be made up of fuse, A.C. contactor, RCD, capacitor and gauge table etc.The upper limit of ambient air temperature is no more than 40 DEG C; The mean value of ambient air temperature 24h is no more than 35 DEG C; The lower limit of ambient air temperature is not less than-5 DEG C or-25 DEG C.Part distribution box is equipped with radiator fan, and to avoid the too high electrical equipment that causes of temperature normally to work, and in high altitude localities, its ambient temperature is lower, and this mode cannot carry out the improvement of ambient temperature, and then affects stability and the reliability of electrical work.
Utility model content
It can be the constant temperature and humidity vacuum distribution control box controlling temperature in casing, humidity the fire-protection rating that improves provide necessary condition that the technical problems to be solved in the utility model is to provide a kind of.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of constant temperature and humidity vacuum distribution control box, comprises casing and chamber door, and side and the casing of chamber door are hinged, and opposite side arranges the distribution box lock being used for being connected and fixed with casing; It is characterized in that: also comprise a vacuum lead, one end of this vacuum lead and cabinets cavity conducting, the other end of vacuum lead is connected with vacuum pumping pump, and described vacuum lead is provided with vacuum-pumping valve; One equalizing main, one end of this equalizing main and cabinets cavity conducting, the other end and the extraneous conducting of casing, described equalizing main is provided with drain tap; Constent temperature heater, humidity sensor, temperature sensor and vacuum detection device are also installed in described casing.
Concrete, the top of described casing is provided with fire extinguishing system, and the top of casing is provided with smoke detector.
Concrete, described casing is die casting aluminium casing.
Concrete, described vacuum-pumping valve is electromagnetic type vacuum pumping valve.
Concrete, described drain tap is electromagnetic type vent valve or manual type vent valve.
Concrete, black box together with described casing is provided with at least with the inner side edge edge of chamber door.
The utility model has the advantage of:
Utilize chamber door, black box coordinate formation one closed cavity with casing, vacuumized in casing by vacuum pumping pump, make the vacuum degree that in casing, maintenance one is relative, reduce interior humidity, thus ensureing that casing can not leak electricity because of humidity, the balancing boom devices such as the contactor in casing will cause hard contact to be oxidized because of the humid air of moist and cabinets cavity; Vacuum degree makes the oxygen content in casing also greatly reduce, and significantly can reduce the generation of fire condition, thus ensure electric safety.In addition, the outfit of constent temperature heater, makes can not to make because temperature is too low in casing balancing boom device cannot normal work group, guarantees the normal operation of each assembly, improves stability and reliability.
In casing, fire extinguishing system and smoke detector are also installed, to put out in time under there is the condition of a fire such as smog in casing; In addition, casing also can install vacuum detection device, temperature sensor and controller additional, itself and vacuum pumping pump, heater, vacuum-pumping valve and drain tap are connected to form an integrated automation control system by controller.
The utility model is applicable to tunnel, mine, High aititude place, the region that is specially adapted to that there was dampness in the air.
Accompanying drawing explanation
Fig. 1 is the utility model constant temperature and humidity vacuum distribution control box structural representation.
Fig. 2 is the utility model constant temperature and humidity vacuum distribution control box outline drawing.
Embodiment
As shown in Figure 1, 2, comprise casing 1 and chamber door 2, casing 1 adopts die casting aluminium material, and side and the casing of chamber door 1 are hinged, and opposite side arranges the distribution box lock 3 or switch that are used for being connected and fixed with casing 1.Black box together with casing 1 is provided with at least with the inner side edge edge of chamber door 2, to ensure the sealing of control cabinet, reduces dust and enters in casing and improve casing air-tightness.
Distribution control box of the present utility model also comprises vacuum lead 4, vacuum pumping pump 5, vacuum-pumping valve 6, equalizing main 7, drain tap 8 and constent temperature heater 9.
One end of vacuum lead 4 and the conducting of casing 1 inner chamber, the other end of vacuum lead 4 is connected with vacuum pumping pump 5, vacuum lead 4 is provided with vacuum-pumping valve 6; One end of equalizing main 7 and the conducting of casing 1 inner chamber, the other end and the extraneous conducting of casing 1, equalizing main 7 is provided with drain tap 8, and drain tap 8 is electromagnetic type vent valve or manual type vent valve.Constent temperature heater 9, humidity sensor, temperature sensor and vacuum detection device are also installed in casing 1.
