Abstract
The utility model, a fix type low voltage switch cabinet with transverse isolation adopts an enclosed construction configuration. The inner part of the switch cabinet is transversally divided into a plurality of layers by an insulating laminated sheet and a light gauge sheet, and a main bus, a branch bus, electrical apparatus elements and the end posts are respectively equipped in corresponding layers. A first line and a second line are guided down and connected with the end posts from one side of the cabinet path. The cabinet efficiently solves the unsafe element existing in present low-tension switch cabinet and prevents electric shock and short-circuited. The switch cabinet has reasonable structure, convenient installation and maintenance, which is a low voltage distribution device suitable for petro-chemical, metallurgy and electric force enterprises.
Description
The utility model belongs to the low-voltage distribution apparatus technical field.
The fixed low-tension switch cabinet that generally uses in industrial enterprise is that some groups of independently electric loops are housed in the open type clothes closet at present, and each loop is made up of main bus bar, branch bar, electric elements, cable etc.These components and parts are installed on the support in the open type clothes closet on request, finish for the distribution task.But this open type switch cubicle because:
(1) live part is exposed in the switch cubicle.Comprise main bus bar; Branch bar under main bus bar draws; Tie between electric elements; The electrified bodies such as joint of electric elements and cable outlet all expose.
(2) electric elements are exposed in the switch cubicle.Comprise that three-phase fuse between phase and phase; Between each independent loop; The normal electrified body of each independent loop electric elements front side; Each independent loop first and second loop terminals row front side; The switch cubicle front side etc. of the normal electrified body of electric elements behind the door all exposes.
(3) the switch cubicle appearance structure is an open type, and upper and lower, left and right and bottom all are open type and unprotect.
So this switch cubicle that uses is easy to get an electric shock or short circuit in operation, inspection, maintenance at present.Particularly when the interruption maintenance of a certain loop, be easy to still contact at the components and parts of operating loop with adjacent, cause and get an electric shock or short circuit.And the fault of any one components and parts all can expand contiguous components and parts to, jeopardizes the safety of whole switch cubicle.Switch cubicle adopts unenclosed construction again, and toy enters switch cubicle by cable trough; Metal objects falls from the top and dust accumulates at exposed components and parts, and accident all can be short-circuited.Get an electric shock and the generation of short circuit, all can cause casualties, equipment damages, cause power failure, parking, cause damage to enterprise.Therefore, this open type switch cubicle is in operation very dangerous, and the electric shock casualty accident happens occasionally, and is difficult to accomplish safety utilization of electric power, safety in production.
The purpose of this utility model is in order to overcome the above-mentioned defective that existing open type low-tension switch cabinet exists, and invention has designed a kind of low-tension switch cabinet of lateral isolation, reduces casualties and equipment breakdown to guarantee safety utilization of electric power.
The utility model is realized by following structure.
In low-tension switch cabinet, laterally separate with the sheet metal of 1 millimeters thick and to be fixed on the switch cubicle frame, make sandwich construction (seeing accompanying drawing 1) like the imaging bookshelf.A side of every layer is shut with the insulating laminated sheet of 20 millimeters thick, and opposite side is an open type, and lead-in wire is by arriving the bottom of switch cubicle herein along first and second lead channels (2) on next door.Door (1) is made for 20 millimeters with the steel plate flanging of 1.5～2 millimeters thick in every layer front side, dress mortise bolt on the door.The switch with fuse handle is equipped with in the front of door, and this handle uses interlocking not open when the closing of circuit state, wants to open the door and must cut off the electricity supply, thereby guaranteed maintenance personal's personal safety.
This switch cubicle divides six layers substantially, and they are busbar laminate (3), branch bar layer (4), electric elements layer (5), first and second lead channels (2), terminal layer (6).Its concrete structure division is as follows:
1, busbar laminate
The busbar laminate design is at the top of switch cubicle, and a side is shut with the insulating laminated sheet of 20 millimeters thick, and this insulating laminated sheet is also as the usefulness of supporting main bus bar.The opposite side of busbar laminate is empty.The bottom of busbar laminate is fixed with screw with the steel plate and the frame by switch cabinet of 1 millimeters thick, forms an independent busbar laminate.
2, branch bar layer
The branch bar arrangement layer has A phase, B phase, C three group of branches buses mutually at the rear portion of switch cubicle.The plexiglass tent insulation blocking of anti-flaming transparent of branch bar group.
3, electric elements layer
Each electric elements layer that independently divides into groups is the main body of this switch cubicle, can have which floor is got well.It is laterally which floor to be separated into sheet metal below the switch cubicle busbar laminate, and steel plate is not to shut one deck is whole, but leaves a space, makes to form one first and second lead channels.As the electric elements mounting panel, this mounting panel and frame by switch cabinet are fixed with screw with the steel plate of 2.5 millimeters thick in every layer back.
4, terminal layer
The terminal layer design is independent one deck at the foot of this switch cubicle.Terminal board is installed in the front portion of this layer.The electric elements secondary line is incorporated into terminal board by first and second lead channels, and secondary connection is very convenient.
This switch cubicle is made Totally-enclosed-type, is converted into 4 head tree frameworks with the steel plate of 2.5 millimeters thick, is welded with 1 millimeters thick steel plate all around.The switch cubicle front is arranged as the lattice wicket of each layer, and the knife switch handle and the inspection hole of interlocking device is housed on the door.The right side of switch cubicle is first and second lead channels, also is equipped with the rectangular wicket of passage.Switch cubicle bottom is except that leaving turnover line cable slotted eye, and all the other are shut without exception, can prevent that like this toy from entering and cause the possibility of short circuit.The bivalve door that can freely open is equipped with in the back of switch cubicle, and door is provided with the shutter of ventilation.
The advantage of the fixed low-tension switch cabinet of lateral isolation is, because the structure that adopts horizontal layering to isolate is separated into several layers with former open type low-tension switch cabinet.Main bus bar, branch bar, electric elements all are arranged in each independent layer, original exposed line and electrified body all are spaced from each other, the fault of both having avoided any one components and parts all can expand adjacent components and parts to and the hidden danger that jeopardizes whole switch cubicle, electric shock and short circuit have also been prevented, reached safety utilization of electric power, the purpose of safety in production.This switch cubicle is totally enclosed type, and is rational in infrastructure, safe in utilization, and installation and maintenance are all very convenient, is a kind of low-voltage distribution establishing that enterprises such as petrochemical industry, metallurgy, electric power use that is suitable for.
