Abstract
The invention discloses a cable house service device for a transformer substation, comprising a rectangular sheet and a plurality of house service holes for cables to pass through, wherein the house service holes are arranged on the rectangular sheet; each house service hole on the rectangular sheet is internally provided with an annular rubber ring which is in sealing connection with the house service hole; cables pass through the inner holes of the annular rubber rings to enter a house; and the cables have good sealing performance with the inner holes, thereby effectively preventing moisture, water, smoke, fire or small animals from entering into a transformer substation; and in addition, as the rubber rings are made of a soft material, when the cables are replaced and overhauled, the cables can be directly pulled with slight force, thereby being very convenient.
Description
Technical field
The present invention relates to the auxiliary equipment that a kind of transformer station uses, especially a kind of transformer station cable house service device.
Background technology
In the prior art, the transformer station of electric power system, switchgear house, the cable turnover family of the overwhelming majority passes in and out by cable trough, and cable trough generally is to pass through fire barrier, anti-chamotte, sandy soil fill or easy method such as lay bricks is come shutoff, its reliability is not high, cause the excesssive gap between cable and the cable trough easily, and then cause moisture, water, cigarette, fire or toy enter in the transformer station via this gap, thereby the safe operation to electric equipment threatens, in addition, come shutoff by above-mentioned method, also to the replacing of cable, maintenance has brought very big inconvenience.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of transformer station cable house service device is provided, this house service device can not only effectively stop moisture, water, cigarette, fire or toy to enter in the transformer station, and can change and overhaul cable easily.
According to a kind of transformer station provided by the invention cable house service device, comprise rectangular thin plate, open the house lead in hole that the some current supply cables on rectangular thin plate pass through, described house lead in also is equipped with an annular rubber ring in the hole, but the endoporus current supply cable of this annular rubber ring passes.
The present invention also has following attached technical characterictic:
Form annular groove on the periphery wall of described annular rubber ring, and this annular rubber ring is connected on the house lead in hole by this annular groove.
The diameter of bore of described annular rubber ring is less than the external diameter of cable.
The internal diameter of described annular groove is greater than the diameter in house lead in hole, and described annular groove width is less than the thickness of described rectangular thin plate.
According to a kind of transformer station provided by the invention cable house service device, have following advantage with respect to prior art:
In this structure, one annular rubber ring is installed in the house lead in hole, is tightly connected between this annular rubber ring and the house lead in hole, cable passes house lead in through the endoporus of this annular rubber ring, and also has good sealing property between cable and the endoporus, thereby this cable house service device can effectively stop moisture, water, cigarette, fire or toy to enter in the transformer station, simultaneously, rubber ring is a soft material, cable being changed, when overhauling, a little firmly being got final product the direct pull cable, very convenient.
Description of drawings
Introduce the present invention in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of master's apparent direction of the present invention;
Fig. 2 is the sectional structure schematic diagram (amplifying the back) of A-A among Fig. 1;
Fig. 3 is the structural representation of annular rubber ring among the present invention.
Embodiment
With reference to Fig. 1; Fig. 2 and Fig. 3; transformer station provided by the invention cable house service device; comprise rectangular thin plate 1; open some house lead ins hole 11 that the current supply cable 2 on rectangular thin plate 1 passes through; one annular rubber ring 3 also is installed in the house lead in hole 11; but endoporus 31 current supply cables 2 of this annular rubber ring 3 pass; form annular groove 32 on the periphery wall of annular rubber ring 3; and this annular rubber ring 3 is connected in the house lead in hole 11 by this annular groove 32; endoporus 31 diameters of annular rubber ring 3 are less than the external diameter of cable 2; after guaranteeing that cable 2 passes endoporus 31; it the gap can not occur each other; guarantee good sealing property, the internal diameter of annular groove 32 is greater than house lead in hole 11 diameters, and the width of annular groove 32 is less than the thickness of rectangular thin plate 1; after guaranteeing that annular rubber ring 3 is installed on the house lead in hole 11, between itself and the house lead in hole 11 gap does not appear.
The foregoing description is only for the usefulness that the present invention is described; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be limited by each claim.
