Background technology
When core is produced, high pressure nitrogen protection is filled in the bringing-up section heating of crosslinking pipe, inside to high-voltage crosslinking production line, and core is exhausted
Edge layer vulcanizes in bringing-up section, while separating out accessory substance, accessory substance is mixed in nitrogen, is touching the stainless steel tube wall of high temperature
When, accessory substance carbonization coking, while producing small particulate matter, is also all entered in nitrogen, and so clean nitrogen is in the circulating cycle
Gradually dirty, Jing after circulating cooling, the accessory substance cooling in nitrogen is changed into greasy dirt from gas, in nitrogen circulation, with nitrogen
Blow to core surface, formed one by one or blocks of oil stain, cause cable core surface contamination.
When high-pressure cross-linking cable runs, electrified voltage is minimum 110 kilovolts, and during operation, the surface temperature of cable reaches 90 degree
More than, the length of every crosslinked cable is all 500 or so, so there is substantial amounts of cable accessory in the circuit of operation.In height
In voltage cable run with load, cable is in the condition of high temperature, and the greasy dirt on core surface can volatilize, and causes pressure in electrical cable aluminium sheath to increase
Height, increased aluminium sheath breakage probability；It is bad that cable surface and oil contaminant when joint is carried out can cause cable to be combined with annex, stays
Accident potential.For meeting to cable high voltage, the requirement of long-time stability, the surface quality of control conductor just seems and its weight
Will.
Therefore those skilled in the art are devoted to developing a kind of greasy dirt of separable cable wire wicking surface and short grained dress
Put.

Preferably, described entrance sleeve one end is fixed with first flange disk, the other end separates pipe flange company with the import
Connect；Described discharge connection one end is fixed with second flange disk, and the other end separates pipe flange connection with the outlet.
For the ease of being connected with nitrogen circulation pipeline, the diameter of the discharge connection is straight less than the outlet separating pipe
Footpath.
For the ease of collecting greasy dirt and fine particle, the surge drum is arranged at the import separating pipe and outlet separating pipe
Junction.
In order to further be easy to collect greasy dirt and fine particle, the import separating pipe, outlet separating pipe and surge drum structure
Into Y-shaped structure.
Preferably, the angle between the import separating pipe and the outlet separating pipe is 135 °.
Preferably, being welded with dowel between the import separating pipe and the outlet separating pipe.
In order to further be easy to collect greasy dirt and fine particle, multiple filter bores on the filter, are provided with；The mistake

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of core surface nitrogen gas and oil dirt and separate small device, separate including the import being connected to each other
Pipe 1 and outlet separating pipe 2.Some filters 3 are provided with the passage of import separating pipe 1 and outlet separating pipe 2, on filter 3
It is provided with multiple filter bores 3a.
As shown in Figure 2 or Figure 3, filter bores 3a are crisscross arranged.As shown in Figure 4 and Figure 5, filter 3 is in each filter bores of correspondence
The exit of 3a is provided with baffle plate 10.
The lower section of import separating pipe 1 and outlet separating pipe 2 is provided with surge drum 4, and the bottom of surge drum 4 is provided with collection valve
5.Surge drum 4 is arranged at the junction of import separating pipe 1 and outlet separating pipe 2.Import separating pipe 1, outlet separating pipe 2 and collection
