Abstract
The utility model discloses a switch cabinet base. The base is of a hollow structure and provided with at least one air hole communicating with the inner cavity of the base, and a filter screen is arranged in the air hole. In use, a switch cabinet is mounted on the base, geogas in the pit and outdoor air realize convection through the air hole, so insulation aging of a cable caused by falling of water drops formed by geogas penetrating into the switch cabinet is prevented, frequency of faults of the switch cabinet is reduced, economic losses of an electric power company or user caused by the fault of the switch cabinet are avoided, and reliability of power supply is improved.
Description
Technical field
The utility model relates to a kind of switch cubicle, particularly relates to a kind of be used to the switch cubicle base that makes down-hole ground vapour and open-air convection current.
Background technology
City net switch cubicle is in running, because the bottom of cabinet bulk basis is in sealing state for a long time, and the base plate shutoff is not in place, cause the ground vapour of down-hole constantly in switch cubicle, to permeate, simultaneously, because the switch cubicle internal-external temperature difference is bigger, make the ground aerosolization that is penetrated in the switch cubicle form condensation, condensation is attached on the inwall of switch cubicle and forms the globule gradually, the globule is dropped on the cable T-shape head and causes ageing of insulation, produces the flicker discharge, long-play, will inevitably produce faults such as single-phase earthing or phase fault, influence normal power supply.
At above-mentioned deficiency, the applicant has explored a kind of switch cubicle base, can make down-hole ground vapour and open-air convection current by this switch cubicle base, avoid ground vapour to be penetrated into the interior globule that forms of switch cubicle and be dropped in the ageing of insulation that causes on the cable, reduce the fault frequency of switch cubicle, improved the reliability of power supply.
The utility model content
In view of this, the utility model provides a kind of switch cubicle base, can make the down-hole ground vapour to outdoor convection current by this switch cubicle base, avoid ground vapour to be penetrated into the interior globule that forms of switch cubicle and be dropped in the ageing of insulation that causes on the cable, reduce the fault frequency of switch cubicle, improved the reliability of power supply.
The utility model solves the problems of the technologies described above by following technological means: a kind of switch cubicle base, described base are hollow-core construction, and base is provided with at least one and the air-vent that its inner chamber is communicated with, and are provided with filter screen in the described air-vent.
Further, described base is rectangular.
Further, described base around be equipped with an air-vent.
Further, described air-vent is rectangular, and it is of a size of 600mm * 300mm.
Further, described base adopts concrete to be built into.
The beneficial effects of the utility model are: switch cubicle base of the present utility model, described base are hollow-core construction, and base is provided with the air-vent that at least one is communicated with its inner chamber.During use, switch cubicle is installed on the base, the ground vapour of down-hole is by air-vent and open-air convection current, avoid ground vapour to be penetrated into the interior globule that forms of switch cubicle and be dropped in the ageing of insulation that causes on the cable, reduced the fault frequency of switch cubicle, avoid the economic loss of bringing for Utilities Electric Co. or user because of the switch cubicle fault, improved the reliability of power supply.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to accompanying drawing the utility model is elaborated, as shown in Figure 1: the switch cubicle base 2 of present embodiment is hollow-core construction, and base 2 is rectangular, be provided with an air-vent 21 that is communicated with its inner chamber around the base 2, air-vent 21 is rectangular, and air-vent 21 is of a size of 600mm*300mm.During use, switch cubicle 1 is installed on the base 2, the ground vapour of down-hole is by air-vent 21 and open-air convection current, avoid ground vapour to be penetrated into the switch cubicle 1 interior globule that forms and be dropped in the ageing of insulation that causes on the cable, reduced the fault frequency of switch cubicle, avoid the economic loss of bringing for Utilities Electric Co. or user because of the switch cubicle fault, improved the reliability of power supply.
As further improvement in the technical proposal, be provided with filter screen in the air-vent 21, filter screen is used for preventing that the rubbish thing from entering the back and stopping up air-vent 21, thus guaranteed the down-hole ground vapour can with the open-air convection current.
As further improvement in the technical proposal, base 2 adopts concrete to be built into, and compares and adopts steel plate, and its cost is lower, is conducive to reduce maintenance cost.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
