A low-voltage frequency conversion speed regulating device

Abstract

The invention discloses a novel low-voltage variable-frequency speed regulation device. The novel low-voltage variable-frequency speed regulation device comprises a main low-voltage variable-frequencyspeed regulation device body, wherein a casing is arranged in the middle of the main low-voltage variable-frequency speed regulation device body; buttons are arranged on one side of the casing; a display is arranged at the top end of the buttons and forms an integrated structure with the buttons; sliding columns are arranged on two sides of the main low-voltage variable-frequency speed regulationdevice body and form an integrated structure with the main low-voltage variable-frequency speed regulation device body; a groove is formed in the middle of each sliding column. With the arrangement of the sliding columns and fixed columns, mounting and dismounting steps of the low-voltage variable-frequency speed regulation device are improved, working content is simplified, so that the device ismore efficient, all that is required for a worker is to align the sliding columns to sliding chutes in the fixed columns and slowly slide the sliding columns down, damping springs and rubber pads inthe bottom ends of the fixed columns have a protecting effect on the low-voltage variable-frequency speed regulation device, the mounting is simplified, time is saved, meanwhile, working difficulty ofthe worker is reduced, and practicability is improved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage frequency conversion speed regulation, and in particular relates to a low-voltage frequency conversion speed regulation device.

Problems solved by technology

[0004] The purpose of the present invention is to provide a low-voltage variable-frequency speed-regulating device to solve certain problems in the use and installation of the existing low-voltage variable-frequency speed-regulating device proposed in the above background technology. When it comes to the control cabinet, various tools are needed to complete it, and some nuts are very small, which are easy to be lost during transportation, and the installation time is long. Because the low-voltage frequency conversion speed control device is more important, and the traditional installation method only More bolts and fixing holes can be added, which not only consumes time, but also increases the difficulty of the work of the staff, and creates certain unfavorable factors for the staff. The existing low-voltage frequency conversion speed control device has poor heat dissipation when used for a long time , because the low-voltage frequency conversion speed control device is installed inside the control cabinet, the internal heat dissipation performance of the low-voltage frequency conversion speed control device is poor. It makes the machine unable to operate normally, which brings bigger and more serious problems, which not only delays the work progress of the staff, but also reduces economic benefits and other issues
