Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0042] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded as limiti...

Abstract

The invention relates to the technical field of communication and provides a closed type optical fiber pass-through device and a processing method thereof. The device comprises a flange, an installation plate and optical fiber pass-through devices, wherein each of the optical fiber pass-through devices comprises a main body with a through hole, a ceramic inserted core, and two sleeves; the ceramic inserted core is bonded inside the through hole; the ceramic inserted core is provided with a light-permeable bare optical fiber encapsulated with glue; the two sleeves are positioned inside the through hole and sleeve on two ends of the ceramic inserted core. According to the device, the airtightness of the optical fiber pass-through device inside is guaranteed through glue binding sealing mode inside the optical fiber pass-through device; threaded connection is adopted between the optical fiber pass-through device main body and the installation plate, and screw thread assembling play the role of sealing so that the sealing grade of the closed type optical fiber pass-through device is increased, and the sealing effect is good; meanwhile, due to the simple overall structure of the closed type optical fiber pass-through device, less space occupation, simple processing method and small cost, large scale production and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically, relates to a sealed optical fiber penetration device applied to an oil-immersed transformer and a processing method thereof. Background technique [0002] Large oil-immersed transformer is one of the core equipment of the backbone power grid, and its internal temperature change directly affects the performance of the transformer. The oil-immersed transformer box is a closed container. When detecting the internal temperature of the oil-immersed transformer, it is necessary to let the optical fiber temperature sensor penetrate the transformer box wall into the inside of the transformer, and the position where the optical fiber temperature sensor penetrates the transformer box wall will be There is a problem with seal leakage. [0003] In terms of solving the problem of seal leakage at the penetration of transformers, some domestic scientific research institutions and e...
