According to the device, the soil corrosion and ageing research of cable and sheath materials in a lab is made.

Description

A kind of cable and the aging accelerator of oversheath soil corrosion
Technical field
The utility model belongs to cable and oversheath corrosion and protection technical field, especially a kind of cable and the aging accelerator of oversheath soil corrosion.
Background technology
Civilian and industrial electric power cable, no matter supply voltage is high pressure (take 110kV as main), middle pressure (1-30kV) or low pressure (220-380V), is all buried conventionally.In intermediate and low electric network, adopt plastic insulated cable, they need not take extra anticorrosive measure.There is the cable of copper shield and plastic sheath to there is enough corrosion resistances.The lead sheath cable of the steel armouring of only wrapping up with the jute of impregnating pitch just has corrosion dangerous.Equally, once it is damaged to have lead sheath cable and the corrugated steel jacketed cable plastics of plastic protective jacket layer, also have corrosion dangerous.The cable of 110kV also has similar problem, and this high-tension cable normally uses steel sheath buried, and steel pipe scribbles pitch or plastic protective cover outward.Cable, owing to being directly embedded in soil or being laid in underground pipeline, if protect improper metal and non metallic sheath destroyed by corrosion and ageing, makes moist in cable, water inlet, causes cable insulation against ground to reduce, and affects power supply reliability and serviceable life.Therefore, attach great importance to the soil corrosion problem of aging of underground cable and sheath material both at home and abroad, soil corrosion rule and the corrosion of research cable and sheath material, have important theory significance and using value.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of cable and the aging accelerator of oversheath soil corrosion.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of cable and the aging accelerator of oversheath soil corrosion, comprise experimental box body, upper left side in casing is fixed with liquid reserve tank, the inwall of the left side wall of liquid reserve tank and roof and experimental box body fits tightly, on the left side wall of liquid reserve tank, by valve, by pipeline, be separately installed with pH table and the conductivity table that is placed in experimental box body left hand external, roof outside at liquid reserve tank is fixed with the liquid feed valve by pipeline communication, right side wall bottom at liquid reserve tank is fixed with tapping valve, upper right side at experimental box body is fixed with parameter measuring device, parameter measuring device includes pH electrode, zwitterion detector and potentiostat, in the lower horizontal of liquid reserve tank tapping valve, be fixed with the porous plate of experimental box body midfeather, on the base plate of experimental box body, be fixed with support, on support, settle tested cable, one end of tested cable is connected with the detection output terminal of potentiostat, porous plate bottom uniform filling in test casing covers the microorganism sulfate reduction soil bacteria of tested cable, the pH electrode probe of described parameter measuring device and zwitterion detector probe are all embedded in microorganism sulfate reduction soil bacteria, the blowoff valve of pipeline UNICOM is installed in the bottom of experimental box body.
And the pipe end place in described blowoff valve enters experimental box body soil is provided with the filter screen that prevents that earth from entering.
And described support is two of left and right brace table, the two ends of tested cable are placed on two brace tables in left and right.
And described porous plate is the porous plate that aperture that polythene material is made is 3-4mm.
Advantage of the present utility model and good effect are:
