Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more particularly to an anti-clogging breather and transformer. Background Technology

[0002] The current main transformer oil conservator and the breather structure of the on-load tap changer are quite similar. There is a metal filter screen at the connection between the inner and outer covers of the oil cup and the oil surface. Due to the long-term operation of the breather and the quality of the silica gel block inside, as well as the vibration of the main transformer, some silica gel debris will fall into the filter screen and the oil cup. At the same time, dirt in the oil and these silica gel debris will accumulate in the filter screen. Over the years, they may even completely block the breather, causing the main transformer to be unable to breathe, which is a serious consequence. Summary of the Invention

[0003] The purpose of this invention is to provide an anti-clogging breather and transformer to solve the problem of dirt in the oil and the accumulation of these silica gel debris in the filter screen.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Firstly, an anti-clogging respirator includes:

[0006] A silicone container with an internal air chamber containing a silicone block.

[0007] A first pipe is connected to the bottom of the silicone container and communicates with the air cavity;

[0008] A sludge collector is sealed to the bottom of the first pipe;

[0009] Oil cup; and

[0010] The second pipe connects the oil cup and the first pipe, wherein the silicone container, the first pipe, the second pipe, and the oil cup are sequentially connected to form a breathing passage, and the waste debris of the silicone block can be collected into the sludge collector through the first pipe.

[0011] Waste debris in the silicone container can be deposited in the sludge collector through the first pipe. The silicone container, the first pipe, the second pipe, and the oil cup are sequentially connected to form a breathing passage, preventing waste debris from entering the breathing passage and clogging the oil cup.

[0012] Preferably, the bottom of the silicone container is provided with a tapered guide surface that is wider at the top and narrower at the bottom, and the center of the guide surface is connected to the first pipe.

[0013] The waste debris can be guided directly and accurately into the first pipe by the conical guide surface.

[0014] Preferably, the first pipe extends in a vertical direction.

[0015] The first pipe extends vertically to facilitate the rapid falling of waste into the sludge collector.

[0016] Preferably, the sludge collector is detachably and sealed to the first pipe.

[0017] The sludge collector is detachably connected to the first pipe, allowing for easy removal of the sludge collector and regular cleaning of debris.

[0018] Preferably, the sludge collector is threadedly connected to the first pipe.

[0019] The threaded connection between the sludge collector and the first pipe facilitates a sealed and detachable connection between the two.

[0020] Preferably, the second pipe extends in a straight line, and the end of it that connects to the first pipe is lower than the other end.

[0021] A small amount of debris carried by the airflow can continue to deposit in the second duct and eventually fall into the sludge collector.

[0022] Preferably, the system also includes two rain covers, one of which covers the first pipe and the sludge collector, and the other of which covers the oil cup.

[0023] The rain cover can prevent rainwater from entering the respirator on rainy days.

[0024] Preferably, a connecting limb is provided between the oil cup and the silicone container.

[0025] The connecting limb provides stability to the oil cup.

[0026] Preferably, the oil cup includes:

[0027] The inner cover of the oil cup has its top end connected to the second pipe;

[0028] An oil cup outer cover contains oil, with the bottom of the inner cover positioned within the oil; and a filter screen is positioned at the bottom of the inner cover.

[0029] Secondly, a transformer, including the aforementioned anti-clogging breather.

[0030] The oil cup is less prone to clogging, resulting in a longer transformer lifespan.

[0031] The beneficial effects of this invention are:

[0032] For the anti-clogging respirator, the waste in the silicone canister can be deposited in the sludge collector through the first pipe. The silicone canister, the first pipe, the second pipe, and the oil cup are connected in sequence to form a breathing passage, preventing waste from entering the breathing passage and clogging the oil cup.

[0033] For transformers, the oil cup is less likely to get clogged, resulting in a longer transformer lifespan. Attached Figure Description

[0041] Example 1

[0042] This invention provides an anti-clogging respirator, see [link to relevant documentation]. Figure 1 The anti-clogging respirator includes a silicone canister 1, a first pipe 2, a sludge collector 3, an oil cup 4, and a second pipe 5.

[0043] An air cavity is formed inside the silicone container 1, and a silicone block is placed inside the air cavity to absorb water vapor in the airflow. In this embodiment, the silicone block and the silicone container 1 are arranged coaxially, and the silicone block occupies 2 / 3 of the volume of the silicone container 1.

[0044] The first pipe 2 is connected to the bottom of the silica gel container 1 and communicates with the air chamber of the silica gel container 1. It can be understood that the gas enters the first pipe 2 downward after being dried by the silica gel block.

[0045] The sludge collector 3 is sealed to the bottom of the first pipe 2, allowing silica gel block debris to fall into it through the first pipe 2. Because the sludge collector 3 is sealed to the first pipe 2, it does not affect the drying efficiency of the airflow within the first pipe 2.

[0046] The second pipe 5 connects between the oil cup 4 and the first pipe 2. The silica gel container 1, the first pipe 2, the second pipe 5, and the oil cup 4 are sequentially connected to form a breathing pathway. The gas path is as follows... Figure 1 As indicated by the arrow.

[0047] The waste from the silicone block is concentrated in the sludge collector 3 at the bottom of the first pipe 2, and is not easily allowed to enter the oil cup 4 on the side.

[0048] In this embodiment, the first pipe 2 extends vertically. This can be understood as the first pipe 2 and the silicone container 1 being arranged coaxially, facilitating the collection of silicone block debris.

[0049] The sludge collector 3 is detachably connected to the first pipe 2. When the sludge collector 3 collects a large amount of waste, it can be removed and cleaned in time.

[0050] The sludge collector 3 is threadedly connected to the first pipe 2. In this embodiment, the sludge collector 3 has an internal thread, and the first pipe 2 has a matching external thread. At the same time, the inner wall of the sludge collector 3 is provided with a sealing ring that can seal against the first pipe 2.

[0051] The second pipe 5 extends in a straight line, with one end connecting to the first pipe 2 lower than the other end. Airflow enters the second pipe 5, and if there are silicone block debris, it will settle and slide into the first pipe 2 as it rises towards the oil cup 4, and then continue to fall into the sludge collector 3.

[0052] It should be noted that the second pipe 5 can also be set to other shapes, such as S-shaped or wavy.

[0053] Furthermore, the anti-clogging respirator provided in this embodiment also includes two rain covers 6, one of which shines on the outside of the first pipe 2 and the sludge collector 3, and the other rain cover covers the outside of the oil cup 4.

[0054] Furthermore, a connecting member 11 is provided between the oil cup 4 and the silicone container 1. One end of the connecting member 11 is fixedly connected to the outer wall of the silicone container 1. In this embodiment, the connecting member 11 is integrally formed on the outer wall of the silicone container 1. One end of the connecting member 11 is provided with a threaded hole extending in the vertical direction, and the oil cup 4 is threadedly connected to the threaded hole in the vertical direction.

[0055] It should be noted that the oil cup 4 includes an inner oil cup cover 41, an outer oil cup wall 42, and a filter screen 43. The top of the inner oil cup cover 41 is connected to the second pipe 5; the outer oil cup cover 42 contains oil, the bottom of the inner oil cup cover 41 is located in the oil, and the filter screen 43 is located at the bottom of the inner oil cup cover 41.
