Description
Technical field
The utility model relates to the hermetically sealed cross connection grounding case of a kind of stainless steel.
Background technology
For high voltage single-core cable system, suitable cable cover(ing) earthing mode should be adopted according to actual conditions, the power cable of 5kV heavy in section power cable and 66kV, 110kV and above is single-core cable, interconnected and the ground connection of cable metal sheath one end three-phase, the other end is earth-free, when lightning wave or internal overvoltage flow along cable core, the earth-free end of cable metal sheath there will be higher impulse overvoltage, or when system short-circuit fault current flows through cable core, the earth-free end of its sheath also there will be very high line-frequency induction overvoltage.Above-mentioned overvoltage may puncture protective coverings of cable insulation, causes cable metal sheath multipoint earth faults, has a strong impact on power cable and normally runs and even significantly reduce cable useful life.Therefore cable protective layer protector must be adopted to limit induced voltage on power cable metal sheath (or metallic sheath) and fault overvoltage according to the regulation of power industry standard DL/T401-2002 " high voltage power cable selects directive/guide "; usually; for the induced voltage on restriction power cable metal sheath and fault overvoltage; and avoid forming circulation in sheath; the direct ground connection in cable metal sheath one end, the other end then must pass through protector ground connection.If circuit is longer, also cable sheath should being divided three sections of (or multiple section of three) mutually insulateds, by protector ground connection after the sheath crossbonding of segmentation place, for better adapting to the demand in market, being badly in need of a kind of product meeting existing market and require of research.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, what provide a kind of improvement has anti-theft function, and performance of ventilating is good, installs and uses easy, external form is small and exquisite attractive in appearance, the hermetically sealed cross connection grounding case of good insulation preformance stainless steel.
The utility model solves the technical scheme that its technical problem adopts: the hermetically sealed cross connection grounding case of a kind of stainless steel; there is casing; one side of casing is provided with cable entrance hole; cable entrance hole is provided with copper tip; the conductor adapting piece be connected with cable entrance hole is provided with in casing; conductor adapting piece is provided with protector, and protector is connected with insulation board by connecting copper bar.
Further, described casing adopts 304 stainless steel materials to make, and high, the anti-leakage trace of good insulation preformance, dielectric strength, anti-galvanic corrosion, heat-resisting, cold-resistant, corrosion-resistant, ageing-resistant, explosion-proof lamp advantage and good chemical stability, sealing, intensity is high.
Further, the upper surface of described cable entrance hole is provided with water-proof seal adhesive tape.
Further, the outer surface of described casing is provided with fixed installation sole, is convenient to the installation of grounding box and fixes, there is good anti-theft function.
Further, described casing is provided with several and installs screw hole, install screwed hole and be convenient to the fixing of casing, intensity is high, easy for installation, and external form is small and exquisite attractive in appearance, long service life, reduces production cost.
The beneficial effects of the utility model are, electrical apparatus insulation performance of the present utility model is good, dielectric strength is high, anti-leakage trace, anti-galvanic corrosion, heat-resisting, cold-resistant, corrosion-resistant, ageing-resistant, explosion-proof lamp advantage and good chemical stability, sealing, intensity is high, easy for installation, there is anti-theft function, performance of ventilating is good, installs and uses easy, and external form is small and exquisite attractive in appearance.
