For this reason, designer of the present utility model is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of open air and concentrates earth terminal case, to overcome above-mentioned defect.
Utility model content
The purpose of this utility model is to provide a kind of outdoor concentrated earth terminal case, and its structure is simple, easy to operate, and it is convenient that Installation and Debugging are safeguarded, fail safe is high, and flexibility is good.
For solving the problem, the utility model discloses a kind of outdoor concentrated earth terminal case, comprising rectangular casing, it is characterized in that:
The front and back opening of described casing and bottom is provided with moisture barrier, is filled with barrier material in described moisture barrier;
The top of described casing is provided with rainproof top cover, and described rainproof top cover is the Pagoda-shaped from top to bottom flaring, and the open front of described casing is hinged with front chamber door, and after-opening is hinged with rear chamber door,
The bottom of described casing is also provided with outward extending L-type support portion, and the upper end of described casing is also provided with Temperature Detector and heating unit, and described temperature detector electrical is connected to heating unit.
Wherein: in described casing, be also provided with grounding copper bar, described grounding copper bar is provided with self coupling change return cable installing hole summation current transformer.
Wherein: described grounding copper bar is arranged on installing rack, described installing rack is vertically arranged in casing.
Wherein: described casing is made by cold-rolled steel sheet, its outer surface has protective coating.
Wherein: described protective coating is that electrostatic plastics dust layer.
Wherein: described front chamber door is provided with front door lock and handle, described rear chamber door is provided with back door lock and handle.
Known by said structure, open air of the present utility model concentrates earth terminal case to have following effect:
1, structure is simple, and handling are convenient, widely applicable;
2, safe moisture proof, provides better environment, and avoid temperature too low or too high, security performance is better.
Detailed content of the present utility model obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
