Abstract
The utility model relates to a nonmetal enclosure bus closed low-voltage distribution box, which comprises a box body, a plurality of commutators, a plurality of breakers, a bus, a bus bracket and a PEN row. Two vertical holding frames are respectively fixed at both sides of the box body, two horizontal holding frames are fixed in parallel between the vertical holding frames, and two or more bus supports are fixed on the two horizontal holding frames; the multiple bus supports are used to jointly fix a three-phase bus, while a plurality of communicators connected with breaker are hung in parallel on the three-phase bus. As the box body of the utility model is made of fibreglass reinforced polyester materials, the enclosure is fully insulated and has high insulation strength; by adopting an advanced closed bus system, the electric elements are directly connected on the bus, therefore, the bus is not only an electric conductor, but also performs as a supporting member for the electric elements; meanwhile, the bus system completely seals the bus rod behind the electric elements, and no charged body is exposed at the front side. Thus, the utility model has the advantage of greatly improving the safety of the operation as well as the maintenance staff.
Description
[technical field]
The utility model relates to low voltage electrical equipment, the closed low-tension distribution box of particularly a kind of non-metal shell bus.
[background technology]
Outdoor closed low-tension distribution box is the electric equipment that is widely used in fields such as electric power system, urban construction, railway traffic, petrochemical industry, real estate.In the prior art, this distribution box adopts metal cabinet more, and its insulating properties, corrosion resistance and heat preservation and insulation are poor, and useful life is short.Simultaneously, existing connected mode is that electric elements are installed on the fixed panel, by bus punching, bolt connecting mode bus rod and branch bar are installed then, this punching segmentation connected mode, bus rod and branch bar are all exposed, and processing safety is low, not only expends installation work-hour, and contact resistance is increased, increased accident potential.And the erecting bed need be beforehand with concrete pedestal, and construction period is longer, inconvenience construction in winter.
[utility model content]
The purpose of this utility model is intended to for overcoming the deficiencies in the prior art, and provides a kind of non-metal shell bus closed low-tension distribution box, the shell all insulation of this distribution box, and the bus connection of not punching has improved moving, thermal stability and operation stability.
The utility model has designed the closed low-tension distribution box of a kind of non-metal shell bus for addressing the above problem, it comprises the casing that is provided with button fly front, adapter, circuit breaker, bus, bus structure and NPEN row, it is characterized in that: each fixes a longitudinal bracing frame both sides in described casing, fixes two cross-brace framves side by side between this both sides longitudinal bracing frame, and be fixed with two or more bus structures on two cross-brace framves; Described several bus structures are used for jointly fixedly three-phase bus, then mount a plurality of adapters that are connected with circuit breaker on the three-phase bus side by side.
The beneficial effects of the utility model are: casing adopts the fibre-glass reinforced polyester material to make, the shell all insulation, have mechanical strength height, in light weight, corrosion-resistant, anti-aging, long service life, heat preservation and insulation is good, dielectric strength height, anti-electric arc, remarkable advantage such as fire-retardant.And the door of casing and backboard up and down two ends design ventilation hole is arranged, radiating effect is good, can effectively prevent condensation.Casing all adopts plank frame, uses simple tool can finish assembling fast, and installation work-hour reduces, and board-like transport of materials and store all very conveniently, and saving takes up room.Adopt advanced enclosed busbar system, bus connections of not punching, improved move, thermal stability and operation stability; Electric elements directly are articulated on the bus, and bus is an electric conductor, are again the strutting pieces of element, saved the space greatly, simultaneously quick for installation, convenient, be convenient to change element and increase and decrease loop, satisfied well distribution box miniaturization, multipurpose, non-maintaining requirement.Bus-bar system is totally-enclosed in the behind of electric component with bus rod, the exposed electrified body of positive nothing, and exposed electrified body area reduces more than 70%, has improved operation and attendant's Personal Safety greatly.Can also bury the ground base according to user's needs apolegamys,, not need concrete pedestal to install, all can construct throughout the year with the distribution box scene of delivering in the lump.The prismatic projection of tank surface can prevent effectively that small advertisement from pasting, and prevents that city " psoriasis " from spreading.
[description of drawings]
The closed low-tension distribution box front view of Fig. 1 non-metal shell bus;
The closed low-tension distribution box end view of Fig. 2 non-metal shell bus.
Be described in detail with reference to accompanying drawing below in conjunction with embodiment of the present utility model.
[embodiment]
The utility model as shown in the figure, by the casing 8 that is provided with button fly front, adapter 14, circuit breaker 3, compositions such as bus 7, bus structure 4 and PEN row 1.Casing adopts fibre-glass reinforced polyester sheet material to assemble.Casing also is provided with ventilation hole 10 at the two ends up and down of backboard and side plate respectively.And casing has outside strip prismatic 16 on backboard, door-plate, side plate and top cover surface, can prevent the small advertisement stickup.Convenient for distribution box is installed, can also connect one under the casing again and bury ground base 9, bury the ground base by the left and right sidewall 11 that is fixed on the support body, rear wall 13 and openable antetheca 12 are formed, and this buries the ground base as if apolegamy, then all can construct throughout the year.
The utility model in casing both sides each fix a longitudinal bracing frame 6, between the vertical fixed mount in these both sides, fix two cross-brace framves 5 side by side, and on two cross-brace framves, be fixed with three bus structures.By three bus structures fixing three-phase bus jointly.And on the three-phase bus between three bus structures, mount four adapters 14.Wherein three bus hooks 15 on each adapter are hung on the three-phase bus, with the bolt on the adapter bus hook are strained and fixed with bus simultaneously.The circuit breaker that is connected on the adapter is connected with outlet with inlet wire 2 respectively.Bus-bar system of the present utility model is totally-enclosed in the behind of electric component with bus rod, does not have exposed bus rod.
Circuit breaker can adopt breaker of plastic casing or switching components such as fuse, fuse disconnecting switch.
