Abstract

The invention discloses a through-wall pipe sleeve structure. A pipe sleeve is a straight metal pipe buried in a wall and is buried in the wall in an inclined mode, and the end in a room is higher than the end out of the room. The through-wall pipe sleeve structure can solve the problem that a through-wall pipe sleeve of a traditional transformer substation leaks water, can greatly eliminate discharging, corona and other safety hidden risks caused by high humidity in the switch room, reduces power failure frequency and improves the capacity of safe power supplying of equipment.

Description

A kind of wall-passing pipe nested structure

Technical field

The present invention relates to the auxiliary tube nested structure using when through walls for electric wire equipment.

Background technique

At present, horizontal arrangement when wall bushing of substation is installed, such layout is easy to occur infiltration phenomenon, long-term ponding, high humidity, insulation can be subject to certain impact, causes the electric discharge of switch indoor electric equipment, sparking, corona phenomenon obvious, to equipment, operation brings serious potential safety hazard, and another impact station holds station appearance and star electric substation creates.As need carry out sleeve pipe place wall plastering, rectification, need when having a power failure, equipment carry out, and supplying power for outside exerts an influence, and has increased workload and funds spending.

Summary of the invention

Technical problem to be solved by this invention is to realize the wall bushing structure that a kind of phenomenon of avoiding seeping water occurs.

To achieve these goals, the technical solution used in the present invention is: a kind of wall-passing pipe nested structure, and pipe box is the metal straight pipe being embedded in body of wall, described pipe box tilts to be embedded in body of wall, and indoor one end is higher than outdoor one end.

Described pipe box one side has breach.

Described pipe box angle of inclination is 25-35 degree.

The breach of described pipe box is positioned at pipe box bottom surface.

Between described pipe box and body of wall, be filled with marine glue.

In described pipe box, be provided with wire, between described wire and pipe box, there is gap.

Described pipe box is filled with marine glue between the wire of outdoor one end and pipe box.

Described pipe box is positioned at outdoor one end and stretches out body of wall, and lower edge is longer than on the upper edge of extension.

Described wire stretches out the outer part of wall and is bowed downward to circular arc, and circle and the external wall at circular arc place are tangent.

The present invention can solve traditional wall bushing of substation place infiltration phenomenon, can greatly get rid of high humidity switch gear room in and the potential safety hazards such as the electric discharge that causes, corona, reduces frequency of power cut, improves the ability that device security is powered.

Accompanying drawing explanation

Below the content of every width accompanying drawing expression in specification of the present invention and the mark in figure are briefly described:

Fig. 1 is sleeve pipe structure schematic diagram;

Fig. 2 is pipe box status architecture schematic diagram through walls;

Mark in above-mentioned figure is: 1, pipe box; 2, breach; 3, wire.

Embodiment

Known referring to Fig. 2, pipe box 1 through walls is for to be embedded in the metal straight pipe in body of wall, tilt to be embedded in body of wall, and indoor one end is higher than outdoor one end when pre-buried, and angle of inclination is controlled at 25-35 degree, preferably 30 degree.

Known referring to Fig. 1, pipe box 1 one sides have breach 2, can increase magnetic resistance like this, and anti-eddy current is excessive, between electrified wire 3 and pipe box 1, also have some cavitations, and in the time of can alleviating like this load current and the variation of ring temperature, wire expands with heat and contract with cold.

For the progressive water-proof performance that improves, between pipe box 1 and body of wall, be filled with marine glue, between pipe box 1 and wire 3, also need to fill marine glue, can cushion wire, especially pipe box 1 needs to be filled with marine glue between the wire 3 of outdoor one end and pipe box 1.The breach 2 of pipe box 1 is positioned at pipe box 1 bottom surface, avoid immersing pipe box 1 from top dialysis water in, pipe box 1 is positioned at outdoor one end and stretches out body of wall, and the upper edge of extension is longer than lower edge, can be used as rain-proof eaves.

Wire 3 stretches out the outer part of wall and is bowed downward to circular arc, the circular arc (considering the rugosity of wire 3) that preferred Qu Chengyi diameter is 5 meters, and circle and the external wall at circular arc place are tangent, just can effectively stop rainwater to enter indoor.

By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
