Embodiment
Fig. 1 is the structural representation of an embodiment mesohigh electricity longitudinal profile for modular gas-filling cabinet; Fig. 2 is an angled arrangement schematic diagram of the modular gas-filling cabinet of the high-tension electricity in Fig. 1, as depicted in figs. 1 and 2, the modular gas-filling cabinet 100 of this high-tension electricity, comprise switch gear room 110, mechanism chamber 120, pressure release passage 130 and voltage transformer room 140, described switch gear room 110 is adjacent with voltage transformer room 140 with described mechanism chamber 120, pressure release passage 130 respectively, and described pressure release passage 130 described switch gear room 110 below and between described switch gear room 110 and voltage transformer room 140; Described voltage transformer room 140 is adjacent with mechanism chamber 120 with pressure release passage 130, and described voltage transformer room 140 is positioned at the below of described mechanism chamber 120; Plug 142, cable 144 and voltage transformer 146 are installed in described voltage transformer room 140, and described cable 144 is connected with described plug 142.
In one embodiment, described high-tension electricity is 1422 millimeters with the height of modular gas-filling cabinet, and width is 750 millimeters; In one embodiment, described plug mounting distance gas-filling cabinet bottom vertical distance is 919 millimeters.
Wherein, the bottom of pressure release passage 130 and the bottom of voltage transformer room 140 at grade, and are the bottom of high-tension electricity with modular gas-filling cabinet 100.
The modular gas-filling cabinet of above-mentioned high-tension electricity, voltage transformer is arranged on high-tension electricity with in modular gas-filling cabinet, do not need additionally to increase voltage transformer cabinet, provide cost savings, and save space, cable is connected with plug, and plug distance gas-filling cabinet bottom 919 millimeters, facilitate cable routing, do not need the height additionally increasing gas-filling cabinet, provide cost savings, reduce and take up room.
Above-mentioned gas-filling cabinet generally does outgoing line cabinet, can left and right extension cabinet type, and adopts full-insulated full-sealed, and all electrification in high voltage parts are positioned at stainless steel casing, and case shell is that stainless steel soldering and sealing connects, and is filled with the SF6 gas of operating pressure 1.4 handkerchief; When internal arc pressure is too large, gas is discharged by explosion-proof valve, ensures the safety of the people in front, cable and other equipment; Cabinet body structure is compact, small in volume, easy for installation, the mode of connection is flexible, simple to operate, safe and reliable, non-maintaining; Energy reliable ground; Chargedly can touch, be furnished with stress cone, connected mode is fixed step by step, and hermetically sealed nothing exposes electrified body, anti-dust, tolerance inundation by flood; All cable joints and annex are applicable to cross-linked polyethylene insulated cable; Cable connector plug, cable connector adopt the charged tangible cable joint of silicon rubber prefabricated flood control, there is semiconductive shielding layer on surface, charged tangible, totally-enclosed plyability is adopted to insulate, T-shaped connection conicity locking step by step, constant compression is fastenedly connected, and watertightness is very good, and silicon rubber has good hydrophobicity and migration of hydrophobicity, good springiness tear-proof, anti-dust, anti-aging, anti-freezing is white, the invasion and attack of corrosion-resistant, resistance to flood.This switch cubicle can be AC metal closed formula, fixing or units combination type combined fixed switch arrangement.
The above embodiment only have expressed several execution mode of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility; some distortion and improvement can also be made; these all belong to protection range of the present utility model, and therefore, the protection range of the utility model patent should be as the criterion with claims.
