Referring to fig. 1 and 2, the novel disassembly-free oil-immersed transformer respirator of the present invention comprises a respirator body 100, and further comprises,

the bottom of the flange 200 is connected with the upper part of the respirator body 100 through a pipeline;

the mouth sealing structure 300 comprises a silica gel injection hole 301 arranged on the respirator body 100 and used for injecting replaced silica gel into the respirator body 100 without disassembling the respirator body, and a sealing bolt 302 is arranged in the silica gel injection hole 301.

When needing to change the silica gel that discolours in the respirator body 100, screw out sealing bolt 302, the port that silica gel filling hole 301 and respirator body 100 lower part itself have forms the route, discharge the inside silica gel that discolours of respirator body 100, treat that silica gel exhausts the back, add silica gel again to respirator body 100 inside through silica gel filling hole 301, it can to screw up sealing bolt 302 afterwards, the realization is to the change of silica gel that discolours under the prerequisite of not demolising whole respirator body 100, save time and manpower, the complexity of operation has been reduced.

In an embodiment, referring to fig. 2 and 3, although the breathing port of the conventional respirator is placed in the insulating oil in the oil cup, which can ensure the isolation of particles such as dust and the like in air entering the capsule, the insulating oil amount increases with the increase of the capacity of the oil-immersed transformer, and the transformation amplitude of the insulating oil amount increases with the temperature. Under low temperature environment, insulating oil mass reduces, can inhale the capsule with insulating oil in the oil cup in, leads to the oil cup to lose the isolation to particulate matter such as dust in the air. The insulating oil is absorbed into the capsule, and can also corrode the capsule to a certain degree; in order to solve the above technical problem, the respirator further comprises an air filter 500 arranged at the lower part of the respirator body 100 for filtering, and the air filter 500 is connected with the respirator body 100 through a connecting bolt 400.

In one embodiment, referring to fig. 3 and 4, the air filter 500 includes a housing 501 having a filter element cavity, a filter element 504 disposed in the inner cavity of the housing 501, an upper end cap 502 disposed on the upper portion of the housing 501, a connection head 503 connected to the upper end cap 502, and a breathing port 505 disposed on the lower portion of the housing 501 and communicated with the filter element cavity, the breathing port 505 is used as a passage for air to enter and exit the capsule (the capsule is disposed inside the oil conservator, and belongs to the prior art structure), and the connection head 503 is in threaded fastening connection with the connection bolt 400. The filter element 504 is used for filtering dust particles in the outside air; through the setting of empty filter 500, when the insulating oil mass in the transformer changed along with ambient temperature, under the condition of guaranteeing to get into particulate matters such as dust in the capsule air isolation, the capsule shrink more freely, also can avoid insulating oil to the inside corruption of capsule.

When the air filter 500 is used, the sealing bolt 302 is firstly detached, and then the air filter 500 is detached, so that all the discolored silica gel in the respirator body 100 is discharged. After the silica gel was discharged, the air filter 500 was installed. Then, dry silicone rubber is injected from a silicone rubber injection hole 301 in the upper part of the respirator body 100, and finally, the silicone rubber injection hole 301 is sealed by using a sealing bolt 302.

In one embodiment, the upper cap 502 is threadably coupled to the housing 501, such that the upper cap 502 is easily removed, thereby facilitating replacement of the filter element 504; and the upper end cap 502 and the connecting head 503 are internally provided with passages communicated with the inner cavity of the respirator body 100. Facilitating the passage of air through the air filter 500 and the respirator body 100 into the conservator.

In one embodiment, the lower portion of the respirator body 100 is funnel-shaped. By the arrangement, the efficient and complete discharge of the discoloring silica gel in the respirator body 100 is facilitated when the discoloring silica gel is replaced.

In one embodiment, a double layer of sealing rubber ring is sleeved on the sealing bolt 302. This arrangement facilitates improving the sealability at the silicone rubber injection hole 301.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the present invention.
