Abstract

The invention discloses a frequency conversion cabinet controlled by a membrane switch, which comprises a frequency conversion cabinet body. The frequency conversion cabinet body comprises a cabinet body, and a controller and a frequency converter arranged in the cabinet body. The frequency conversion cabinet controlled by the membrane switch is characterized in that the membrane switch is arranged on a front panel of the cabinet body, the membrane switch is connected with the signal input end of the controller through a pin flat cable, the signal output end of the controller is connected withthe signal input end of the frequency converter, and the membrane switch is used for receiving input signals to control the working state of a power device connected with the signal output end of thefrequency converter. Thus, the power device connected with the frequency conversion cabinet is controlled through the membrane switch, the common button switch in the prior art is replaced, the waterproof and dustproof effects are good, the service life is long, the after-sale maintenance is convenient, the after-sale problem of equipment with a damaged control switch can be solved easily even byoperators without training, the membrane switch only needs to be replaced, the pin flat cable is reconnected, the after-sale efficiency is greatly improved, and the after-sale cost is reduced.

Description

technical field [0001] The invention relates to the technical field of frequency conversion cabinets, in particular to a frequency conversion cabinet controlled by a membrane switch. Background technique [0002] The frequency conversion cabinet is a control cabinet that uses a frequency converter to drive the power device. Because of its good starting performance, speed regulation performance and energy-saving effect, it has become the currently popularized power drag method. The high-power frequency conversion cabinet can minimize the impact of high-power water pumps and fans on the power grid and the pressure drop of the chief mate, and the power saving effect is remarkable. Frequency conversion cabinets are widely used in various types of tap water supply systems, such as processing equipment for agricultural and sideline products, cleaning equipment for agricultural products such as radishes and potatoes, constant pressure frequency conversion water supply for construc...
