Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology for power electronic equipment, specifically a quick-release and fixing clamp for temperature measurement optical fiber of rectifier cabinet rectifier element. Background Technology

[0002] During the operation of a rectifier cabinet, rectifier components (such as diodes and thyristors) are the core components, undertaking the crucial task of converting alternating current (AC) to direct current (DC). Because rectifier components generate a large amount of heat when powered on, if the temperature is too high and cannot be dissipated in time, it may lead to performance degradation, accelerated aging, or even breakdown and damage, resulting in equipment failure or system shutdown, seriously affecting the safe and stable operation of the power system. Therefore, real-time monitoring of the temperature of rectifier components is essential. Real-time acquisition of component surface temperature data via temperature-sensing fiber optic cables can promptly detect potential overheating hazards, enabling early warning and preventative maintenance, thereby ensuring the long-term reliable operation of the rectifier cabinet and extending equipment lifespan.

[0003] However, in traditional methods, the fixing and disassembly of temperature-sensing optical fibers typically rely on thermally conductive silicone for bonding. This method has significant drawbacks: First, the thermally conductive silicone requires a long curing time, affecting the efficiency of fiber installation; second, the silicone fixing is for single use, and disassembly requires damaging the silicone layer, a cumbersome and time-consuming process that hinders the regular cleaning and maintenance of rectifier components; furthermore, silicone fixing is prone to loosening under vibration, potentially leading to fiber displacement or poor contact, affecting the accuracy of temperature measurement data. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a quick-release and fixing clamp for the temperature-sensing optical fiber of the rectifier element in a rectifier cabinet. During the cleaning and maintenance of the rectifier element, maintenance personnel can rotate the clamp outward to quickly separate the clamp and the optical fiber from the rectifier element. This effectively solves the problems of time-consuming and complicated disassembly of the temperature-sensing optical fiber, effectively standardizes the fixing and wiring of the temperature-sensing optical fiber, is convenient to use, simple to operate, inexpensive, and easy to promote, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release and fixing clamp for temperature measuring optical fiber of rectifier element in rectifier cabinet, comprising a buckle and a rod. The bottom of the buckle is integrally connected to the rod through a buckle base. The end of the buckle away from the buckle base has a buckle opening, making the buckle C-shaped. The buckle opening faces the insulating tube for fixing the rectifier element and is pressed for installation. The rod has an inclined optical fiber fixing groove. The upper surface of the rod away from the buckle has a fold line, and the end of the rod near the fold line is at an angle to change the angle of the optical fiber.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a quick-release and fixing clamp for temperature measuring optical fiber of rectifier element in rectifier cabinet, including a buckle 1 and a rod 2. The bottom of the buckle 1 is integrally connected to the rod 2 through a buckle base 6. The buckle 1 has a buckle opening 4 at the end away from the buckle base 6, making the buckle 1 have a C-shaped structure. The buckle opening 4 is pressed and installed towards the insulating tube for fixing the rectifier element. The rod 2 has an inclined optical fiber fixing groove 3. The upper surface of the side of the rod 2 away from the buckle 1 has a fold line 7, and the end of the rod 2 near the fold line 7 has a bend angle 8, which is used to change the angle of the optical fiber.

[0017] Furthermore, the inner side of the buckle 1 is provided with damping corrugations 5.

[0018] Furthermore, the two ends of the optical fiber fixing groove 3 are an optical fiber inlet 301 and an optical fiber outlet 302, respectively, and the optical fiber fixing groove 3 is provided with a protruding inlet fixing point 303 at the part corresponding to the optical fiber inlet 301, and the optical fiber fixing groove 3 is provided with a protruding outlet fixing point 304 at the part corresponding to the optical fiber outlet 302.

[0019] Furthermore, at the fiber outlet 302 inside the fiber fixing groove 3, the portion from the fold line 7 to the fold angle 8 is pressed and fixed to the side of the fixed rectifier element, with the pressing point of the fold line 7 being the outermost point of the rectifier element.

[0020] When using: Press the buckle 1 onto the fixed insulating sleeve of the rectifier element. The optical fiber passes through the optical fiber fixing groove 3, and the fixing point inside fixes the optical fiber to prevent it from retracting. Rotate the clamp to press it onto the rectifier element. The clamp bend angle 8 changes the angle at which the optical fiber passes through, so that it contacts and fits the rectifier element. The damping corrugation 5 inside the buckle 1 generates damping after connecting with the insulating sleeve, preventing the clamp from loosening due to vibration of the rectifier equipment, which would affect the accuracy of temperature measurement.

[0021] This invention allows maintenance personnel to rotate the clamp outwards during the cleaning and maintenance of rectifier components, enabling the clamp and optical fiber to be quickly separated from the rectifier components. This effectively solves the problems of time-consuming and complicated disassembly of temperature-sensing optical fibers, and effectively standardizes the fixing and wiring of temperature-sensing optical fibers. It is convenient to use, simple to operate, inexpensive, and easy to promote.
