Disclosure of Invention
To not enough among the above-mentioned background art, the utility model provides a withstand voltage seal cover of insulating oil has solved the technical problem of the oil cup oil leak of current withstand voltage tester of insulating oil.
The technical scheme of the utility model is realized like this: the utility model provides a withstand voltage seal cover of insulating oil, the cover is established outside oil cup and the outer protective sleeve of insulating oil withstand voltage tester, establishes the seal cover main part of the recess form outside the oil cup including the cover, and the both sides an organic whole of seal cover main part is connected with the extension seal cover of tube-shape, and the extension seal cover is established in the outside of protecting the section of thick bamboo outward, and seal cover main part and extension seal cover are elastic sleeve and upper end and all are provided with the opening.
Furthermore, the length of the extension sealing sleeve is smaller than the distance between the outer wall of the oil cup and the connecting sleeve of the outer protective sleeve, so that the extension sealing sleeve can be prevented from interfering with the connecting sleeve, and the sealing and leakage-proof effects can be achieved.
Further, the opening is higher than the vertex of the outer protective cylinder, so that the sealing range is prevented from being not in place, and the insulating oil in the oil cup is prevented from leaking from the upper position of the outer protective cylinder.
Furthermore, the end of the opening close to the oil cup is arranged at an interval with the outer protective cylinder and is higher than the top point of the outer protective cylinder, and the end of the opening far away from the oil cup is attached to the outer wall of the outer protective cylinder, so that the sealing reliability is fully ensured.
Further, the two extending sealing sleeves on the two sides of the oil cup are symmetrically arranged relative to the center line of the oil cup.
The utility model discloses a seal cover main part and the integrative setting of extension seal cover can fully guarantee sealed effect, accept the oil leak of the inside axostylus axostyle of outer casing and oil cup junction, not only simple structure, easily preparation, it is convenient to dismantle moreover, easily washs and changes.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
A pressure-resistant sealing sleeve for insulating oil is disclosed, as shown in fig. 1 and 2, insulating oil for test is placed in an oil cup 4 of an insulating oil pressure-resistant tester, two opposite electrode discs 7 are arranged in the oil cup 4, each electrode disc 7 is connected with a shaft rod 6 penetrating through the oil cup 4, one end of the shaft rod 6 is connected with the electrode discs 7, and the other end of the shaft rod is inserted into an electrode seat. In order to prevent the insulating oil from leaking from the joint of the shaft lever 6 and the oil cup 4, an outer protective cylinder 5 is sleeved outside the shaft lever 6, one end of the outer protective cylinder 5 is connected with the outer wall of the oil cup, and the other end of the outer protective cylinder is inserted into a connecting sleeve sleeved with an electrode holder, wherein the electrode holder and the connecting sleeve are not shown in the drawing.
The sleeve is arranged outside an oil cup 4 and an outer protective cylinder 5 of the insulating oil pressure resistance tester and comprises a groove-shaped seal sleeve main body 1 arranged outside the oil cup 4 in a sleeved mode, two sides of the seal sleeve main body 1 are integrally connected with a cylindrical extension seal sleeve 2, and the extension seal sleeve 2 is arranged outside the outer protective cylinder 5 in a sleeved mode.
