Embodiment Construction
[0019] In order to better understand the technical solutions of the present invention, specific embodiments will be described in detail below in conjunction with the accompanying drawings.
[0020] see Figure 1 to Figure 3 , a support 4 for lugs at the base of an oil-immersed fuse, including an arc-shaped bottom plate 41, and a long strip-shaped through hole 42 is opened along the arc-shaped direction of the arc-shaped bottom plate 41, and the through hole 42 connects the arc The arc-shaped bottom plate 41 is divided into front and rear parts, and the width of the front portion 411 of the arc-shaped bottom plate 41 is greater than the width of the rear portion 412 of the arc-shaped bottom plate 41. The upper surface of the arc-shaped bottom plate 41 is located at the front and rear of the through hole 42, and the first boss 43 and the second boss 44 are arranged in a one-to-one correspondence, and the height of the first boss 43 is smaller than the height of the second boss 4...

The invention discloses a supporting piece for a lug plate of an oil-immersed fuse base. The supporting piece comprises an arc-shaped bottom plate. A strip-shaped through hole is formed in the arc-shaped bottom plate in the arc direction of the arc-shaped bottom plate. A first boss and a second boss which are arranged correspondingly are arranged on the upper surface of the arc-shaped bottom plate and located in front of the through hole and behind the through hole respectively. The height of the first boss is smaller than that of the second boss. The length of the first boss and the length of the second boss are equal to the length of the through hole. The width of the first boss is smaller than that of the front portion of the arc-shaped bottom plate. The width of the second boss is equal to that of the rear portion of the arc-shaped bottom plate. The outer surface of the first boss and the outer surface of the second boss are both in an arc-shaped curved surface shape. The supporting piece is mounted on the lug plate and can effectively prevent the lug plate from fracturing after the lug plate is bent frequently and prolong the service life of the lug plate.
Description
technical field [0001] The invention relates to a support for lugs of oil-immersed fuse bases. Background technique [0002] The base of a conventional high-voltage oil-immersed fuse includes a housing, two lugs and two conductive rings respectively fixed on the inner wall of the housing. The housing is in a cylindrical structure, and the two lugs are arranged one by one At positions corresponding to the two conductive rings of the casing, and the two lugs are located outside the casing, one end of the two lugs penetrates the casing along the radial direction of the casing and is connected to the two conductive rings one by one correspondingly. In the prior art, the lug needs to be bent during use, and the lug is easily broken after being bent many times. . Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a support for the lugs of the oil-immersed fuse base, which is installed on the lugs and ...
