CN205069290U - Novel transformer respirator - Google Patents

Abstract

The utility model discloses a novel transformer respirator, which comprises an upper end cover, a silica gel tank, a lower end cover and an oil cup. The bolts are fixedly connected; the upper and lower end covers are respectively provided with a silica gel inlet and a silica gel outlet connected to the inside of the silicone tank, an arched mesh plate is provided at the bottom of the silicone tank, and a silicone tank is provided on the lower end cover. Internally communicated exhaust holes, and the exhaust holes are located under the arched mesh panel. The utility model solves the problem of air leakage caused by poor sealing between the long bolts located in the pipe body through the long bolts located outside the silica gel tank; an arched mesh plate is arranged at the inner bottom of the silica gel tank, which effectively prevents the silica gel from blocking the vent hole, and does not affect breathing.

Description

A new type of transformer respirator

technical field

The utility model relates to a novel transformer respirator.

Background technique

As we all know, the transformer is the main equipment in the power system, and its safe and stable operation directly affects the reliability of the power supply. The flange at the center of the top of the silicone tank is formed to ensure that the gas in the capsule of the transformer oil conservator is dry and prevent water vapor and dust from entering the oil conservator. At present, most of the respirators used have several disadvantages: 1. It is inconvenient to replace the silica gel, and the sealing performance of the respirator decreases after replacement; 2. The design of the breathing hole is seriously unreasonable, which may easily cause the breathing blockage of the respirator; When connecting between the upper and lower end covers, a long bolt passes through the upper end cover, the silica gel tank and the lower end cover in turn, and the connection between the long bolt and the upper end cover is easily leaked due to poor sealing.

Contents of the invention

In order to overcome the problems in the prior art, the purpose of this utility model is to provide a novel transformer respirator.

In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A new type of transformer respirator, including an upper end cover, a silicone tank, a lower end cover and an oil cup, the silicone tank is installed between the upper and lower end covers, and the upper and lower end covers are fixedly connected by long bolts located outside the silicone tank; The upper and lower end caps are respectively provided with a silica gel inlet and a silica gel discharge port connected to the interior of the silica gel tank, an arched mesh plate is provided at the bottom of the silica gel tank, and an exhaust port connected to the interior of the silica gel tank is provided on the lower end cover. holes, and the vent holes are located under the arched mesh panel.

Further, both the silica gel inlet and the silica gel outlet are provided with sealing covers.

Due to the above-mentioned technical scheme, the utility model has the following advantages:

1. The long bolts are located outside the silicone tank, which solves the problem of air leakage caused by poor sealing between the long bolts in the tube body;

2. An arched mesh plate is set at the bottom of the silicone tank, which effectively prevents the silicone from clogging the exhaust hole and does not affect breathing;

3. By setting the silica gel inlet and silica gel discharge port on the upper and lower end caps, it is convenient to replace the silica gel in the silica gel tank.

detailed description

The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a new type of transformer respirator includes an upper end cover 1, a silicone tank 2, a lower end cover 3 and an oil cup 4, the silicone tank 2 is installed between the upper and lower end covers, and the upper and lower end covers pass through The long bolt 5 located on the outside of the silicone tank 2 is fixedly connected; the upper and lower end covers are respectively provided with a silicone inlet 6 and a silicone outlet 7 connected to the inside of the silicone tank 2, and an arched The mesh plate 8 is provided with a vent hole 9 communicating with the inside of the silicone tank 2 on the lower end cover 3 , and the vent hole 9 is located below the arched mesh plate 8 .

Both the silica gel inlet and the silica gel outlet are provided with sealing covers.

Compared with the prior art, the utility model is as follows: the long bolts are located outside the silica gel tank, which solves the problem of air leakage caused by poor sealing between the long bolts located in the pipe body; an arched mesh plate is arranged at the inner bottom of the silica gel tank to effectively prevent the silica gel from being blocked Vent hole, and does not affect breathing; by setting the silica gel inlet and silica gel outlet on the upper and lower end caps, it is convenient to replace the silica gel in the silica gel tank.
