Description

A kind of indoor substation isosceles triangle outlet structure

Technical field

The utility model is related to a kind of substation structures, more specifically, it relates to which a kind of indoor substation isosceles triangle goes out Cable architecture.

Background technology

Indoor substation is a kind of influence in order to avoid outdoor weather condition, and equipment is mounted on the power transformation in building It stands.

Electric wire in indoor substation needs to lead to outdoor from the roof of main house body or side wall, to realize power supply, There are certain gap between the electric wire and roof of extraction, water is easy gap from there and enters indoor substation, leads to internal device The short circuit of part, common method mainly by roof carry out waterproof operation, make water be not easy from the gap on electric wire and roof it Between flow into, but waterproof material after prolonged use be easy aging, so that the effect of waterproof is reduced, lead to the roof of indoor substation Generate leak.

Utility model content

In view of the deficienciess of the prior art, the utility model lies in that providing a kind of indoor substation isosceles triangle goes out knot Structure has the effect of reducing leak probability.

To achieve the above object, the utility model provides following technical solution：A kind of indoor substation isosceles triangle outlet Structure, including main house body, multigroup power transmission line in isosceles triangle distribution is provided in the main house body, and the power transmission line runs through The top of the main house body and side wall are provided with support component, the house between the power transmission line and the main house body Fairlead is offered on the top of main body, and water repellent component, the waterproof group are provided between the power transmission line and the fairlead Part includes the sealing ring being fixedly connected on the fairlead inner wall, the waterproof jacket being set on the power transmission line, is fixedly connected The waterproof jacket both ends sealing ring, be threaded in the waterproof ring on the waterproof jacket and being obliquely installed, be fixedly connected on Gasket at the top of the main house body, the inner wall of the sealing ring and the outer wall of the waterproof jacket contradict, and the waterproof ring is remote Towards the top droop of the main house body, the edge of the waterproof ring is entrenched in the gasket for one end from the waterproof jacket It is interior.

By using above-mentioned technical proposal, worker rotates waterproof ring, so that the edge of waterproof ring is pressed on gasket, work as rain When water is fallen, sealing ring blocking rainwater enters in waterproof jacket, and waterproof ring guides rainwater, so that rainwater is left guard tube arrival close Packing, since the contact position between waterproof ring and gasket is more close, rainwater is difficult to enter, to flow to main house body top Portion, sealing ring and waterproof jacket further stop water, make shipwreck to enter in main house body, reduce main house body top The probability of portion's leak.

The utility model is further arranged to：Closed component is provided between the sealing ring and the waterproof jacket, it is described Closed component include several mating grooves being opened on the sealing ring inner wall, several be fixedly connected on the waterproof jacket Cooperation bulge loop on outer wall, the cooperation bulge loop are entrenched in the mating groove.

By using above-mentioned technical proposal, bulge loop and mating groove is coordinated to work in coordination, when flow such as sealing ring and waterproof When between set, make water flows through distance increase so that water is not easy to flow into inside main house body, reduces leakage at the top of main house body The probability of water.

The utility model is further arranged to：Several water-rings, the water-ring are fixedly connected in the waterproof jacket The outer wall of inner wall and the power transmission line contradict, the water-ring is distributed along the axle center of the waterproof jacket.

By using above-mentioned technical proposal, the setting of water-ring makes to form water proof storehouse one by one in waterproof jacket, hinders The flowing of water makes shipwreck to be entered inside main house body by the gap between waterproof jacket and power transmission line, reduces house master The probability of leak at the top of body.

The utility model is further arranged to：Lead-in chamfered is offered on the sealing ring, the lead-in chamfered is far from institute The one end for stating power transmission line is tilted towards the waterproof ring.

By using above-mentioned technical proposal, the setting of lead-in chamfered makes water that can be moved under self gravitation effect, and leaves Sealing ring reduces the time that water-water reactor accumulates on sealing ring, reduces gap of the water between sealing ring and power transmission line and enter waterproof Probability in set.

The utility model is further arranged to：The drainage inclined-plane being obliquely installed, institute are offered on the edge of the gasket State the top droop for draining the one end of inclined-plane far from the waterproof jacket towards the main house body.

By using above-mentioned technical proposal, when the water on waterproof ring is flow on gasket, effect of the water in its own gravity Lower edge drains inclined-plane movement, enables water to the surface for leaving gasket faster, reduces water between gasket and waterproof ring The probability leaked in gap.

The utility model is further arranged to：The support component includes first be arranged at the top of the main house body Supporting rack, the second supporting rack being arranged on the main house body side wall, first supporting rack include being fixedly connected on house First support bar in main body, is fixedly connected on first at the head rod being fixedly connected between the first support bar Leading-off rods on strut, the power transmission line are mounted on the head rod and the leading-off rods, the second supporting rack packet Include the second support bar being fixedly connected in main house body, be fixedly connected on the second support bar between the second connecting rod, The power transmission line is mounted in second connecting rod.

By using above-mentioned technical proposal, power transmission line can be hung by first support bar and second support bar, be made defeated It is not likely to produce and influences each other between electric wire, the setting of leading-off rods enables the power transmission line being located at the top of main house body to stretch out, and makes defeated Electric wire is not easily susceptible to the influence of main house body.

The utility model is further arranged to：Connection is provided between the first support bar and the head rod Part, is also equipped with connector between the second support bar and second connecting rod, the connector includes being fixedly connected on Clamping piece in the first support bar and second support bar is fixedly connected on the head rod both ends and the second connecting rod There is the fixinig plate at both ends gap, the fixinig plate to be located between the clamping piece and the first support bar, second support bar In the gap.

By using above-mentioned technical proposal, when worker needs to overhaul power transmission line, worker can be incited somebody to action by connector Head rod and the second connecting rod are removed, and fixinig plate can be embedded in gap by worker after maintenance, carry out the first connection The fixation of bar and the second connecting rod facilitates the operation of worker.

The utility model is further arranged to：It is fixedly connected with several on the leading-off rods and places bar, the placement bar Length direction along the leading-off rods is distributed.

By using above-mentioned technical proposal, power transmission line can be placed to placing and be guided on bar, make the arrangement of power transmission line compared with It is neat, reduces the interference between power transmission line.

In conclusion the utility model has the advantages that：

1, by the way that water repellent component is arranged, make shipwreck to be flowed into main house body in the gap between power transmission line and fairlead Portion reduces the probability that leak occurs at the top of main house body, protects the transformation facility in main house body；

2, by the way that support component is arranged, so that power transmission line is supported, while being arranged to power transmission line, reduce Interfering with each other between power transmission line.
