2. feature-rich be applicable in of the utility model is installed in the common low-voltage cabinet such as GCK, GCS, it is able to achieve fast power restoration;It can Do not have a power failure installation, does not need to expand and stops range, has very strong versatility.
3. the utility model overall weight is small, small in size, and can dispense, it is easy to carry about with one.
Detailed description of the invention
Fig. 1 is the utility model integrated connection figure
Fig. 2 is the utility model electricity getting device structure chart
Fig. 3 is the utility model power taking head structure chart
In figure:1- bridge switch device, 2- flexible wires, 3- fixed bin, 4- power taking head, 31- limit hole, 32- plug handle, 33- adjusting screw, 34- action pane, 35- fixation hole, 41- main circuit move plug-in unit, 42- fixinig plate.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and embodiments.
Please referring to Fig. 1, the present embodiment provides a kind of drawer type common switchgears, including two electricity getting devices, several flexibilities Line 2 and a bridge switch device 1, it is characterised in that:Two electricity getting devices pass through flexible wires 2 respectively and connect with bridge switch device 1;Institute It states electricity getting device and is made of fixed bin 3 with the power taking head 4 for being fixed on fixed bin bottom;Described 2 one end of flexible wires and power taking head 4 connect It is connected to inside fixed bin 3, the other end is drawn from the upper end of fixed bin 3 and connect with bridge switch device 1.
In an embodiment of the utility model, further, the power taking head 4 moves plug-in unit 41 and fixinig plate 42 by main circuit Composition." power taking head " is formed using universal " main circuit moves plug-in unit " with " fixinig plate " independently processed.It primarily serves and original The general docking of power supply unit, carrying circuit principal current effect(Within 400A), can be adapted to according to loop current size." fixinig plate " It is matching according to the size of " main circuit moves plug-in unit " processing, using galvanized sheet aperture, cutting." fixinig plate " frame size 180mm is (long)*70mm(It is wide)*2mm(It is thick), hole size 154mm*44mm.
