Abstract
The utility model discloses a kind of seal of direct-current switch cabinet, comprise the insulation board below the cabinet being positioned at direct-current switch cabinet, described insulation board is arranged along the surrounding of cabinet lower surface.The utility model has the advantages such as simple and compact for structure, with low cost, easy for installation.
Description
Technical field
The utility model is mainly concerned with field of track traffic, refers in particular to a kind of seal being applicable to the direct-current switch cabinet that track traffic is powered.
Background technology
Feeding System of Urban Rail Transit adopts DC1500V overhead contact line to power, and take rail as reflux type.For reducing stray electrical current, corrosion is produced to civil engineering structure reinforcing bar, rail, equipment metal shell and other underground metal pipelines, general DC traction power-supply system is designed to isolated neutral system, insulating mounting is adopted to direct-current switch cabinet, rail is insulated by insulation cushion and the earth, to reach the object reducing stray electrical current and leak.
As depicted in figs. 1 and 2, at present, the insulating mounting of direct-current switch cabinet arranges monoblock rigid insulation plate 2 between the metal shell and basic channel-section steel 3 of cabinet 1, and basic channel-section steel 3 is positioned on ground 4, and insulation board 2 adopts epoxy resin board or Merlon insulation board two kinds usually.Wherein, during epoxy resins insulation plate hight temperature, mechanical strength is high, and under high humidity, dielectricity is more stable, has flame resistance, and has good machining property.Merlon insulation board mechanical strength is high, has good dimensional stability, and under high humidity, dielectricity is stablized.Shortcoming is easy to crack, facile hydrolysis during high temperature, and coefficient of friction is large, and resistance to wear and fatigue durability are all lower.When carrying out direct-current switch cabinet in insulating mounting, need on basic channel-section steel 3, first carry out screen cabinet location, be fixed on by insulation board 2 after on basic channel-section steel 3 and carry out equipment installation again, this mounting means adds workload and the cost of the installation and maintenance of engineering staff.
Direct-current switch cabinet is generally multiple devices and installs side by side, comparatively large owing to installing rear volume side by side, the normal method adopting the fissure of displacement to install, and the insulation board seam 7 namely between the seam of adjacent cabinet 1 and adjacent insulation board 2 forms the shape that mutually staggers.In insulation board seam 7, place takes grinding process, and bonds with insulating cement.Final insulation board 2 is spliced by a few bulk insulation board parts, and the entirety of insulation board 2, than the whole frame width of equipment, length dimension each larger (such as: 10mm), covers on basic channel-section steel 3, to ensure the insulation of framework.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existed for prior art, the utility model provides a kind of seal of direct-current switch cabinet simple and compact for structure, with low cost, easy for installation.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A seal for direct-current switch cabinet, comprises the insulation board below the cabinet being positioned at direct-current switch cabinet, and described insulation board is arranged along the surrounding of cabinet lower surface.
As further improvement of the utility model: described cabinet is two or more, along the orientation of multiple cabinet, the length of described insulation board equal all cabinets be arranged side by side after length sum; Along the thickness direction of cabinet, the length of described insulation board is certain value.
As further improvement of the utility model: described insulation board is one block of whole plate and is formed with periphery, whole direct-current switch cabinet bottom surface along consistent square frame shape.
As further improvement of the utility model: described insulation board is by polylith veneer splicing.
Compared with prior art, the utility model has the advantage of: direct-current switch cabinet seal of the present utility model, be just arranged in the surrounding place, below of cabinet, reduce workload and the cost of the installation and maintenance of engineering staff; Meanwhile, insulation board can also adopt non-whole plate mode, and the veneer of prefabricated some can also reduce the veneer quantity of insulation board like this, and easily transport and installation, reduce workload and the cost of the installation and maintenance of engineering staff.

Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As shown in Figure 3, direct-current switch cabinet comprises more than one cabinet 1, and when cabinet 1 is multiple, the mode that employing is arranged side by side successively forms a complete switch cubicle.Direct-current switch cabinet seal of the present utility model, comprise be positioned at direct-current switch cabinet cabinet 1 below the insulation board 2 of surrounding, namely insulation board 2 is fixed on the below of cabinet 1, and arranges along the surrounding of cabinet 1 lower surface.The length of insulation board 2 is the length sum after all cabinets 1 are arranged side by side.
When embody rule, insulation board 2 can be spliced by polylith separate board, or is a complete plate body.When for complete plate body, can be formed by prefabricated according to the concrete size of switch cubicle, install at the scene.When for polylith separate board, can first form according to the size of concrete size design every block separate board of switch cubicle is prefabricated, and then splicing installation is carried out at scene.
In embody rule example, insulation board 2 comprises the first insulation board 5 and the second insulation board 6 liang of classes, cabinet 1 stock size due to direct-current switch cabinet is regulation, first insulation board 5 with regular length can be set for the thickness direction of cabinet 1, this the first insulation board 5 length when prefabricated is certain, and quantity can be two pieces.Meanwhile, then according to the width of all cabinets 1 of direct-current switch cabinet one or more second insulation board 6 is set.
In the present embodiment, the width of insulation board 2 is preferably 100mm, during installation, is reserved with the insulating board body of 10mm outside device framework.
Adopt direct-current switch cabinet seal of the present utility model and installation method, be just arranged in the surrounding place, below of cabinet 1, reduce workload and the cost of the installation and maintenance of engineering staff; Meanwhile, insulation board 2 can also adopt non-whole plate mode, and the veneer of prefabricated some can also reduce the veneer quantity of insulation board 2 like this, and easily transport and installation, reduce workload and the cost of the installation and maintenance of engineering staff.
Below be only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, protection range of the present utility model should be considered as.
