Summary of the invention
In order to overcome the above-mentioned deficiency that existing static power source exists, the object of the present invention is to provide a kind of twisted and released of the cable formula static power source, static power source is provided with hollow cavity and is connected with case; Frequency converter is located therein; For being located in its radial outside, frequency converter makes full use of the cavity volume of cable reel to cable reel, simultaneously with hollow cavity and frequency converter; The frequency converter occupy-place that saves former separation; The entire length of static power source is reduced more than 40%, and the static power source volume is little, saving passenger shelter bridge lower room thereby satisfy, the requirement that convenient butt joint is installed.
The technical solution adopted for the present invention to solve the technical problems is: a kind of twisted and released of the cable formula static power source; The frequency converter that comprises the input of commercial frequency and line voltage; The heterogeneous output voltage of frequency converter output stablizing; Output voltage is connected on the output cable, and output cable is through the cable reel folding and unfolding, for load provides output voltage.It is characterized by: be provided with hollow cavity and be connected with case, frequency converter is located therein, cable reel with hollow cavity and frequency converter for being located in its radial outside.
Be provided with in the hollow cavity and isolate the air channel, frequency converter output compensating cable is provided with supporting clapboard perpendicular to the cable reel turning cylinder between cable reel and case base plate.
Beneficial effect
Because being axle with the frequency converter, static power source is provided with hollow cavity; Cable reel is axle with the hollow cavity; Make full use of the cable reel cavity volume, save former frequency converter occupy-place, the static power source entire length is reduced more than 40%; The static power source volume is little, saving passenger shelter bridge lower room thereby satisfy, the requirement that convenient butt joint is installed, connected up and control.
