Nuclear power station 1E material contracting with heat refers to accomplish the reactor scram; Containment is isolated, reactor core is met an urgent need cooling, reactor waste is derived, the thermal conductance of containment vessel goes out; Prevent the product of safe level of the electrical system equipment of functions such as radioactive substance ambient discharging.Security class by nuclear power station electrical system equipment is divided three classes: K1, K2, K3.Wherein the K1 series products is installed in the nuclear reactor safety shell, in the function that still can carry out its regulation under the home condition and under SL2 (safe shutdown earthquake is moving) load.Used in nuclear power station 1E level K1 class electric cable accessories is very harsh to material performance requirement; Seriously (can be strong acid or strong basicity environment), big, the long-term serviceability temperature of operating pressure require the stable operation of cable and terminal ability long-term safety up to 90 ℃ to interior irradiation dose high (up to 2000KGy), the chemical corrosion of shell.
Existing 1E level K1 class medium-pressure power cable end product is in the use through long-term rigors; Can occur wrapping up between insulated tube and the fingerstall not tight; Produce the slit, cause problems such as product partial discharge, influenced the normal use at nuclear power 1 E-level K1 class medium-pressure power cable terminal.
Summary of the invention
The utility model discloses a kind of nuclear power 1 E-level K1 class medium-pressure power cable pyrocondensation terminal, and is not tight to occur wrapping up between insulated tube and the fingerstall in the solution prior art, produces the slit, causes problems such as product partial discharge.
The utility model technical solution is characterized in that: power cable is a body, comprises the fluid sealant of anti-irradiation, fingerstall, cable seal pipe; Be coated with the fluid sealant of anti-irradiation, fingerstall, cable seal pipe formation straticulate structure tubulose in proper order at its cable branch place.
The utility model also comprises silicone grease cream, insulated tube, stress tube, copper shield, constant force spring, ground wire; The conductor wire core of cable has had one section stripping outer jacket and inner cushion layer; Many the forked root that compiles of conductor wire core is inserted forked conduction wedge; And hold the fluid sealant of anti-irradiation in the forked root that compiles of conductor wire core; Ground wire is fixed on the copper shield with constant force spring.Fingerstall is inserted in forked root, adds heat fixation to two ends successively by the fingerstall root; Stress tube is inserted in overlap joint screen 20 mm, is heated to shrink and fixes; Conductor wire core evenly is coated with last layer silicone grease cream at insulator surface, is inserted in insulated tube, overlap joint outer jacket 50 mm, and heat shrink is fixed; Terminal and conductor wire core socket crimping are fixed; The place holds the fluid sealant of anti-irradiation at crimp type terminal, holds the big slightly cable size of back diameter, and terminal attaches pipe box and adds heat fixation at terminal adapter position.
The utility model copper shield length outside fingerstall is apart from fingerstall finger tip 55mm; Outer semiconducting layer 5 length outside fingerstall is apart from fingerstall finger tip 20mm
Conductor wire core is forked to be compiled root to hold the fluid sealant of anti-irradiation glue likeness in form olive-shaped, and maximum gauge is greater than the about 15mm of the outside diameter of cable.
Immobile phase colour tube in position.
The utility model good effect is: on the basis of fingerstall; Coating one deck cable bushing pipe again makes and does not have the space in the insulating barrier; Can well solve the partial discharge problem; Can better guarantee simultaneously the stable operation of insulation system long-term safety of this straticulate structure, satisfy the user demand at nuclear power 1 E-level K1 class medium-pressure power cable pyrocondensation terminal.
