Abstract
The utility model discloses a speed governor, particularly to a variable-frequency speed governor, which comprises a cabinet with a display box and an input/output terminal and a variable-frequency speed governor component arranged inside the cabinet. Heat conduction glue is attached on the variable-frequency speed governor component, a heat radiation fin is covered on the heat conduction glue, heat conduction glue is covered on the heat radiation fin, and the heat radiation fin is directly attached with the aluminum cabinet. The variable-frequency speed governor designed through the technical scheme provided by the utility model adopts direct heat radiation through the heat radiation fin, instead of the conventional fan cooling manner, and directly connects the heat radiation fin with the aluminum cabinet, resulting in better heat radiation effect and higher heat radiation capacity.
Description
Technical field
The utility model relates to a kind of speed regulator, is specially a kind of variable-frequency governor.
Background technology
Ac variable speed technology is a Modern Electrical Drive technology important development direction, along with power electronic technology, the application in Alternating Current Governor System of microelectric technique and modern control theory, frequency changing AC speed changing has replaced slip regulating speed in the past gradually, pole changing, governing systems such as DC speed regulation, the many fields that are applied to industrial production and daily life more and more widely.Total institute is known, and the failure rate of frequency converter raises and the rising of exponentially with temperature, and raise and the decline of exponentially with temperature useful life.Ambient temperature rising 10 degree, frequency converter reduces by half average life.When frequency converter was worked, the electric current that flows through frequency converter was very big, and the heat that frequency converter produces also is very large, can not ignore the influence that its heating is produced, and frequency converter is installed in the control cubicle usually, carries fan then, to reach cooling purpose.Yet the fan wind huyashi-chuuka (cold chinese-style noodles) of variable-frequency governor is long-pending less, and radiating rate is slow.
The utility model content
The purpose of this utility model is for a kind of variable-frequency governor is provided, to solve the slow problem of above-mentioned heat radiation of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of variable-frequency governor comprises the cabinet that has display box and input and output terminal, and is arranged at the variable-frequency governor assembly in the cabinet, be fitted with heat-conducting glue on the described variable-frequency governor assembly, coated with fin, coated with heat-conducting glue, directly fit on the fin on the heat-conducting glue with the aluminum cabinet.
Described cabinet side is provided with some thermovents.
Described display box is made up of viewing area and key zone.
Described cabinet is provided with cover plate, and cover plate is connected and fixed by securing member and cabinet, falls into to prevent dust.
By the variable-frequency governor that technical solutions of the utility model design, abandoned traditional fan-cooled mode, adopt fin directly to dispel the heat, and, make radiating effect better by directly being connected with the aluminum cabinet, heat-sinking capability is stronger.
Description of drawings
