Abstract
The title of the utility model is a cable maintenance and water removal device. The utility model belongs to the technical field of cable maintenance in the power industry, and mainly solves the problems of high workload and maintenance cost due to that water left in a cable is not easily removed in cable maintenance. The cable maintenance and water removal device is mainly characterized in that the device comprises a cheer mouth (1), a cable protection sleeve (2) and a nitrogen bottle (3); the cable protection sleeve (2) is a cable heat shrink tube; the cheer mouth (1) is fixed on the cable protection sleeve (2); and the nitrogen bottle (3) is connected through an air tube (4) with the cheer mouth (1). The cable maintenance and water removal device has the characteristics of simple structure, easy operation and good water removal effect, and is mainly used for water removal in cable maintenance.
Description
Technical field
The utility model belongs to power industry cable service technique field, is specifically related to a kind of cable and overhauls the device of removing ponding.
Background technology
In power circuit, the shared proportion of cable increases just gradually.Cable is generally embedded in soil or is laid in indoor, raceway groove, tunnel, and between line, insulation distance is little, without shaft tower, takes up an area less, does not substantially account between hemisphere.Cable is usually used in the lead line in Urban Underground electrical network, power station, in-line power, wind energy turbine set current collection circuit and the mistake river of industrial and mining enterprises, excessively extra large submarine transmission line.Once but power cable breaks down, maintenance difficulty is larger, danger is also large., there is slight crack in transition joint position cracky particularly, makes moisture or water enter cable, affects the insulation property of cable.Because cable is buried underground, draining difficulty, for ensureing safety in production, the general mode that adopts whole cable of replacing, but so just increased cost and workload.Develop the ponding of a kind of device in can emptying cable for this reason, both can reduce maintenance workload, can save again cost.
Summary of the invention
The purpose of this utility model is to provide a kind of ponding in can emptying cable, reduces maintenance workload, and cost-effective cable maintenance de-watering apparatus.
The utility model is realized the technical solution that above-mentioned purpose takes: a kind of cable maintenance de-watering apparatus, is characterized in that: be made up of Air inflating valve, cable protecting sleeve and nitrogen cylinder; Described cable protecting sleeve is cable heat-shrinkable T bush; Described Air inflating valve is fixed on cable protecting sleeve; Described nitrogen cylinder is connected with Air inflating valve by tracheae.In the inflation of cable one end, the other end is discharged the inner ponding of cable.
Cable protecting sleeve described in technical solution of the present utility model and cable contact jaw match.
Cable protecting sleeve described in technical solution of the present utility model is 35KV cable heat-shrinkable T bush.
The beneficial effects of the utility model are: can solve the inner ponding of cable and be difficult for the problem of discharging, improve the convenience of on-site maintenance work.
The utlity model has feature simple in structure, easy to operate, that water removal effect is good.Ponding when the utility model is mainly used in cable maintenance is removed.
