Problems solved by technology

Its disadvantage is: because its motor is relatively large, it can only be fixed in the box A2, and the motor A3 generally requires a frequency conversion motor, so its control box A5 can only be placed or fixed in another location of the factory building , the control box A5 is generally the inverter A51, the inverter and the motor control circuit board A52, so the entire control box A5 is bulky and takes up a lot of space, so it is necessary to separately set the installation space and location of the control box A5 in the factory building

Abstract

The invention discloses a switch speed regulating panel of a large industrial fan. The switch speed regulating panel comprises a variable-frequency motor of the large industrial fan and a frequency changer. The frequency changer is used with the variable-frequency motor, a power switch and a voltage regulating switch of the frequency changer are mounted on a switch panel, a power supply wire of the frequency changer of the large industrial fan is electrically connected onto the power switch, output frequencies of the frequency changer can be regulated by the voltage regulating switch of the frequency changer, the power supply wire and a voltage regulating wire of the frequency changer are routed from a wall of a factory building, the voltage regulating switch of the frequency changer is electrically connected with the frequency changer by the voltage regulating wire of the frequency changer, and the switch panel is fixed into a wire box on the wall by the aid of screws; connector lugs of the power supply wire and the voltage regulating wire of the frequency changer are arranged in the wire box on the wall, and the switch panel covers the surface of the wire box. The switch speed regulating panel has the advantages that the motor of the large industrial fan, the power switch of the frequency converter and a speed regulating switch of the motor are arranged on the same switch panel, accordingly, a control system of the large industrial fan is easy and convenient to mount and small in occupied area, and the integral anesthetics of the factory building cannot be destroyed after the control system is mounted.

Description

Technical field: [0001] The invention relates to the technical field of ceiling fans, and more specifically relates to a panel-type power switch and a speed regulating switch used in large industrial fans. Background technique: [0002] CN203081807U discloses a kind of industrial ultra-large fan, see figure 1 As shown, it is composed of hanger A1, box A2, motor A3 and impeller A4, its motor A3 is fixed in the box A2, the lower end of the hanger A1 is fixed with the box A2, and the impeller A4 is fixed in the motor A3 on the rotating shaft. Its disadvantage is: because its motor is relatively large, it can only be fixed in the box A2, and the motor A3 generally requires a frequency conversion motor, so its control box A5 can only be placed or fixed in another location of the factory building , the control box A5 generally contains the inverter A51, the inverter and the motor control circuit board A52, so that the entire control box A5 is bulky and occupies a large space, an...
