Abstract

The utility model provides an eco -power low -voltage switchgear of a lot of conversion, including casing, a plurality of exhaust smoke and a plurality of fixed spacing unit, the length of perpendicular generating line is greater than the half the of cabinet height degree and is less than cabinet height degree, drawer interval unit adopts the form of once pegging graft unit to be connected with perpendicular generating line, the backplate rigid coupling plug -in switch or the fixed switch of fixed spacing unit are connected with perpendicular generating line and main bus -bar through plug -in switch or fixed switch in proper order, and miniature circuit breaker and backplate rigid coupling, miniature circuit breaker pass through the cable and be connected with plug -in switch or fixed switch electricity. By adopting the above technical scheme, solved technical problem little at installation space and that need two kinds of forms of drawer type and fixed spacing formula to coexist simultaneously, the protect function of effectual completion one -level, two -stage, tertiary circuit breaker and the multistage conversion functions and the control function of circuit breaker, messenger's equipment have the operation protection and perfect advantages such as convenient more.

Description

A kind of Eco-power low-tension switch cabinet that can change more
Technical field
The invention belongs to power supply or the distribution board of distribution, transformer station or switching device field, especially relates to a kind of Eco-power low-tension switch cabinet that can change more.
Background technology
In the prior art, low voltage drawing-out switching carbinet is called for short drawout cubicle, and cabinet body structure under normal conditions, is divided into drawer type or fixed interval formula two kinds.It is only a cabinet body several drawers are installed or several fixed interval partition is installed, is respectively mounted a switch in each drawer or fixed interval, and the condition that two kinds of forms coexist cannot be met.If meeting above two form, then need at least to be completed by two equipment, so not only wasted fund but also needed bigger installing space to realize.Define cannot realize installing space is little and also simultaneously need to the technical barrier that coexists of drawer type and two kinds of forms of fixed interval formula.
Summary of the invention
The problem that the invention to solve is how to provide one both to save installing space, again the low-tension switch cabinet of stable and reliable operation under ensureing the premise of security performance of electric power system.
For solving above-mentioned technical problem, the technical scheme that the invention adopts includes housing, some drawer units and some fixed interval unit, and the length of vertical bus is more than the half of cabinet height and less than cabinet height;Drawer partition unit is connected with vertical bus by a plug connector;The affixed plug-in switch of backboard of fixed interval unit or fixed switch, switched by plug-in or fixed switch be connected with vertical bus and main bus-bar successively.
Described fixed switch connects main bus-bar by cable and vertical bus.
Described plug-in switch connects main bus-bar by vertical bus.
Described fixed interval unit arranges miniature circuit breaker, and described miniature circuit breaker is affixed with backboard, and miniature circuit breaker is electrically connected with plug-in switch or fixed switch by cable.
The backboard of described fixed interval unit is fixed cell insulation board.Described fixed cell insulation board arranges at least 2 opening slots, and miniature circuit breaker is affixed by opening slot and fixed cell insulation board.Described opening slot is connected and sealed by the adhesive tape that insulate.
The invention has the advantage that and has the benefit effect that owing to adopting technique scheme; solve installing space little and also simultaneously need to the technical problem that coexists of drawer type and two kinds of forms of fixed interval formula; effectively complete one-level, two-stage, the defencive function of three grades of choppers and the multistage translation function of chopper and control function so that equipment operation protection improves convenient more;There is simple in construction, the advantage such as easy to maintenance, processing cost is low, production efficiency highly energy-saving, consumption-lowering.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
As shown in Fig. 1 and Fig. 2 combines, the invention includes housing, some drawer units 1 and some fixed interval insulation boards 2, and the length of vertical bus 7 is more than the half of cabinet height and less than cabinet height;Drawer partition unit is connected with vertical bus 7 by a plug connector;The affixed plug-in switch 4 of backboard of fixed interval insulation board 2 or fixed switch.Vertical bus 7 is fixed on cabinet by insulated bus bar clamp 8.Drawer and fixed interval are included in a switch cubicle; effectively utilize space; make two kinds of forms and deposit; when not increasing cabinet, a plug-in switch 4 or a fixed switch are installed in fixed interval, in effective installing space; multiple stage miniature circuit breaker 3 can be installed; to reach the function of multi-stage protection, making the useful space be fully utilized, controlling operation can require to realize according to user.It is connected with vertical bus 7 and main bus-bar 6 successively by plug-in switch 4 or fixed switch.When for fixed switch, the vertical bus 7 at cabinet rear portion passes sequentially through bolt 9, nut and pad and is connected with cable 5;When switching 4 for plug-in, then connect main bus-bar 6, it is achieved the conversion of major loop circuit.Use the form that main busbar and cable 5 share to complete the program.
Described fixed switch connects main bus-bar 6 by cable and vertical bus 7.
Described plug-in switch 4 connects main bus-bar 6 by vertical bus 7.
Described fixed interval insulation board 2 arranges miniature circuit breaker 3, and described miniature circuit breaker 3 is affixed with backboard, and miniature circuit breaker 3 is electrically connected with plug-in switch 4 or fixed switch by cable.Effectively complete the defencive function of one-level, two-stage, three grades of choppers so that equipment operation protection is more perfect
The backboard of described fixed interval insulation board 2 is fixed cell insulation board.Described fixed cell insulation board arranges at least 2 opening slots, and miniature circuit breaker 3 is affixed by opening slot and fixed cell insulation board.Described opening slot is connected and sealed by the adhesive tape that insulate.Install miniature circuit breaker 3 additional, make user in solving small area analysis earth leakage protective circuit, it is to avoid to cause the danger such as line short.
Above an embodiment of the invention is described in detail, but described content has been only the preferred embodiment of the invention, it is impossible to be considered the practical range for limiting the invention.All equalizations made according to the invention application range change and improvement etc., all should still belong within the patent covering scope of the invention.
