Abstract
The invention discloses a shielding body for a 35kV contact box of a switch cabinet. The shielding body comprises an integral conductive nylon ring, wherein the integral conductive nylon ring is arranged on the inner surface of the contact box when used; small holes are fully and evenly distributed in the wall of the conductive nylon ring; two high-voltage leads are symmetrically arranged on the conductive nylon ring; and one end of each high-voltage lead is embedded into the wall of the conductive nylon ring. The shielding body is reasonable in structure; by the integral conductive nylon ring, the shielding body is light in weight and free of a sharp corner, is in a smooth circular ring form as a while, and is free of local discharge when the work testing voltage is 46kV; and the working performance is ensured.
Description
Technical field
The present invention relates to a kind of switch cubicle 35kV contact box shield.
Background technology
Existing switch of switch cabinet cabinet 35kV contact box shield, generally adopts the forms such as copper, aluminium, stainless (steel) wire, the upper and lower side indentation of net, and the body office of causing amplifies, and affects serviceability.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the switch cubicle 35kV contact box shield that serviceability is good.
Technical solution of the present invention is:
A kind of switch cubicle 35kV contact box shield, it is characterized in that: the integral type electroconductive nylon circle being contained in contact box inner surface when comprising use, electroconductive nylon circle wall is evenly covered with aperture, two high-voltage connections are symmetrical arranged on electroconductive nylon circle, and one end of high-voltage connection is embedded in electroconductive nylon circle wall.
The other end of high-voltage connection in the round being convenient to fix, and is fixed by M5 screw with fixed contact pedestal; High-voltage connection comprises upper and lower two sections, is connected between upper and lower side by metal joint.
The muscle shape played the role of positioning is set at electroconductive nylon circle wall inner surface protruding.
The present invention is rational in infrastructure, adopts integral type electroconductive nylon circle, light weight, without wedge angle, entirety is smooth circular, puts that (relevant national standard is: under performance test voltage 26kV under performance test voltage 46kV without office, ≤ 3pc is put in office), ensure that service behaviour.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
