Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, the utility model mainly is made up of parts such as front panel 1.1, right side plate 1.2, reinforcement left side plate 1.3, reinforcement top margin plate 1.4, reinforcement bilge ways 1.5, door lock installing port 2, hinge mounting hole 3, ground hole 4, wiring hole 5, eyelet strip 6, heating panel 7 and heat radiation gaps 8.
Form wicket plate body 1 by front panel 1.1, right side plate 1.2, reinforcement left side plate 1.3, reinforcement top margin plate 1.4 with reinforcement bilge ways 1.5.
The wicket of this low-voltage capacitance cabinet; The right part of plate 1.1 is connected with the right side plate 1.2 that stretches out backward in front; The left part of plate 1.1 is connected with the reinforcement left side plate 1.3 that stretches out backward in front; The top ends of plate 1.1 is connected with the reinforcement top margin plate 1.4 that stretches out backward in front, and the bottom of plate 1.1 is connected with the reinforcement bilge ways 1.5 that stretches out backward in front; The left part of plate 1.1 offers door lock installing port 2 in front; The right-hand member of plate 1.1 offers hinge mounting hole 3 in front; Back surface at the front panel 1.1 of strengthening left side plate 1.3 right positions is fixed with the eyelet strip 6 that stretches out backward; On eyelet strip 6, offer wiring hole 5 and ground hole 4, offer heat radiation gap 8 in front on the plate 1.1.
The front surface of plate 1.1 is provided with protruding forward heating panel 7 in front; On the front panel 1.1 of heating panel 7 orthographic projection positions, offer ventilation hole; Have ventilation gap between the back surface of heating panel 7 and the front surface of front panel 1.1, form described heat radiation gap 8 between said ventilation gap and the ventilation hole.
The ventilation gap that between the front surface of the back surface of heating panel 7 and front panel 1.1, has 0.5 ~ 1.0mm.
The plate body of front panel 1.1 left parts is folded to form described reinforcement left side plate 1.3.
