Abstract
Description
Technical Field
[0001] This application relates to the technical field of transformer auxiliary equipment, and more specifically, to a fixing base for a transformer temperature controller. Background Art
[0002] Oil-immersed transformers need to be equipped with temperature controllers. The temperature controller is installed on the outer wall of the transformer through a fixing base.
[0003] In this regard, Chinese Patent Application No. CN301731147254.1 discloses a fixing base for a transformer temperature controller. This solution mainly uses a fixing groove and a fixing member to cooperate to suspend the temperature controller on the surface of the transformer. At the same time, with the setting of the temperature sensing component, the temperature controller can always sense the temperature of the transformer, and then obtain an accurate transformer temperature value. Specifically, the materials of the fixing part and the contact part are both stainless steel. Through the setting of the return spring, the contact part can always contact the surface of the transformer. Since the materials of the two are the same and the thermal conductivity is the same, the effect of heat transfer is ensured.
[0004] However, in the process of implementing the technical solution in the embodiments of this application, the inventors of this application found that the above technology has at least the following technical problems:
[0005] 1. The temperature sensing component is exposed outside. To improve reliability, stainless steel material is used, so the thermal conductivity is poor.
[0006] 2. Also, because the temperature sensing component is exposed outside, the temperature is dissipated in advance, resulting in inaccurate temperature measurement of the temperature controller. Utility Model Content
[0007] To make up for the above deficiencies, this application provides a fixing base for a transformer temperature controller, aiming to improve the problems mentioned in the above background art.
[0008] An embodiment of this application provides a fixing base for a transformer temperature controller, including a base and a fixing frame. Legs are provided on the back of the base and welded to the transformer. The temperature controller is installed on the fixing frame. The fixing frame is inserted into the base. A heat conduction rod is penetrated through the legs, and a heat insulation sleeve is provided between the heat conduction rod and the legs.
[0009] In a specific implementation, a sliding groove is opened on the base, and the fixing frame is inserted into the base through the sliding groove.
[0010] In a specific implementation, a limiting plate is provided at the lower end of the sliding groove, and a buckle is provided at the upper end of the sliding groove.
[0011] In the above implementation process, the base is welded to the side of the transformer. The fixing frame is inserted into the base from top to bottom through the sliding groove, and the lower end abuts against the limiting plate, and the upper end uses the buckle to ensure that the fixing frame is located in the sliding groove without loosening.
[0012] In a specific embodiment, a heat conduction pad is provided at the lower end of the heat conduction rod.
[0013] In the above implementation process, the heat conduction pad facilitates the fitting of the heat conduction rod to the surface of the transformer, improving the heat conduction ability. In this embodiment, the heat conduction pad is formed by heat conduction silicone grease.
[0014] In a specific embodiment, a through hole for temperature detection is provided on the fixing frame corresponding to the heat conduction rod.
[0015] In the above implementation process, the probe of the temperature controller is fixedly installed at the position of the through hole. When the fixing frame is inserted into the base, the probe directly contacts the heat conduction rod, thereby detecting the temperature of the transformer.
[0016] In a specific embodiment, an inclined surface is provided on the fixing frame and is slidably connected to the heat conduction rod.
[0017] In the above implementation process, the probe of the temperature controller is flush with the bottom surface of the fixing frame. When the fixing frame is inserted into the base, the originally protruding heat conduction rod is pressed in by using the inclined surface, and then the probe of the temperature controller slides onto the head of the heat conduction rod to form contact.
[0018] In a specific embodiment, the fixing frame is U-shaped, and fixing holes are provided on the fixing frame.
[0019] In the above implementation process, the U-shaped fixing frame facilitates the fitting and fixing of the temperature controller, and the fixing holes are used for screwing and installing the temperature controller.
[0020] In a specific embodiment, four legs are provided, and all four legs are hollow, and the heat conduction rod is located in one of the legs.
[0021] In the above implementation process, the legs are used to suspend the temperature controller above the surface of the transformer. All four legs are hollow, which is convenient for unified processing.
[0022] Compared with the prior art, the beneficial effect of this application is that the legs are used to protect the heat conduction rod, so that the heat conduction rod can be made of a material with strong heat conductivity such as copper, and the heat insulation sleeve is used to keep the heat conduction rod warm, thereby avoiding the problem that the temperature is dissipated in advance and the temperature controller detects inaccurately.

[0029] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.
[0030] Please refer to Figures 1-4 , the present application provides a fixing base for a transformer temperature controller, including a base 10 and a fixing frame 30. A support leg 20 is arranged on the back of the base 10 and welded to the transformer. The temperature controller is installed on the fixing frame 30. The fixing frame 30 is inserted into the base 10. A heat conduction rod 40 is arranged through the support leg 20, and a heat preservation sleeve 50 is arranged between the heat conduction rod 40 and the support leg 20. Among them, the support leg 20 is used to protect the heat conduction rod 40, so that the heat conduction rod 40 can be made of a material with strong heat conductivity such as copper, and the heat preservation sleeve 50 is used to keep the heat conduction rod 40 warm, thereby avoiding the problem of inaccurate detection of the temperature controller caused by premature heat dissipation.
[0031] Please refer to Figures 1-4 , a chute is provided on the base 10, and the fixing frame 30 is inserted into the base 10 through the chute. A limit plate 11 is arranged at the lower end of the chute, and a buckle 12 is arranged at the upper end of the chute. The base 10 is welded to the side of the transformer. The fixing frame 30 is inserted into the base 10 from top to bottom through the chute, and the lower end abuts against the limit plate 11, and the upper end uses the buckle 12 to ensure that the fixing frame 30 is located in the chute without loosening.
[0032] Please refer to Figures 1-4 , a heat conduction pad 60 is arranged at the lower end of the heat conduction rod 40. The heat conduction pad 60 facilitates the heat conduction rod 40 to fit with the surface of the transformer and improves the heat conduction ability. In this embodiment, the heat conduction pad is formed by heat conduction silicone grease.
[0033] Please refer to Figures 1-4, a through hole 31 for temperature detection is provided on the fixing bracket 30 corresponding to the heat conducting rod 40. The probe of the temperature controller is fixedly installed at the position of the through hole 31. When the fixing bracket 30 is inserted to the bottom seat 10, the probe directly contacts the heat conducting rod 40, so as to detect the temperature of the transformer.
[0034] Please refer to Figures 1-4 , a slope 32 is provided on the fixing bracket 30 for sliding connection with the heat conducting rod 40. The probe of the temperature controller is flush with the bottom surface of the fixing bracket 30. When the fixing bracket 30 is inserted into the bottom seat 10, the originally protruding heat conducting rod 40 is pressed in by using the slope 32, and then the probe of the temperature controller slides onto the head of the heat conducting rod 40 to form contact.
[0035] Please refer to Figures 1-4 , the fixing bracket 30 is U-shaped, and fixing holes 33 are provided on the fixing bracket 30. The U-shaped fixing bracket 30 is convenient for fitting and fixing the temperature controller, and the fixing holes 33 are used for installing the temperature controller with screws.
[0036] Please refer to Figures 1-4 , four legs 20 are provided, and all four legs 20 are hollow, and the heat conducting rod 40 is located in one of the legs 20. The legs 20 are used to suspend the temperature controller on the surface of the transformer, and all four legs 20 are hollow, which is convenient for unified processing.
[0037] The working principle of the fixing seat of this transformer temperature controller is as follows: The bottom seat 10 is welded to the side of the transformer, the heat preservation sleeve 50 is inserted into the legs 20, then heat conducting silicone grease is applied to the lower end of the heat conducting rod 40, and then the heat conducting rod 40 is inserted into the heat preservation sleeve 50. The temperature controller is installed on the fixing bracket 30, the probe of the temperature controller is fixedly installed at the position of the through hole 31, the fixing bracket 30 is inserted into the bottom seat 10 from top to bottom through the sliding groove, the lower end abuts against the limiting plate 11, and the upper end uses the buckle 12 to ensure that the fixing bracket 30 is not loose in the sliding groove. During the insertion process, the originally protruding heat conducting rod 40 is pressed in by using the slope 32, and then the probe of the temperature controller slides onto the head of the heat conducting rod 40 to form contact. When the heat conducting rod 40 is pressed in, the heat conducting silicone grease is flattened to form a heat conducting pad, which is beneficial to temperature transfer. In summary, the legs 20 are used to protect the heat conducting rod 40, so that the heat conducting rod 40 can be made of a material with strong heat conductivity such as copper, and the heat preservation sleeve 50 is used to keep the heat conducting rod 40 warm, thus avoiding the problem that the temperature is dissipated in advance and the temperature controller detects inaccurately.
