Description
Technical Field
The utility model relates to the technical field of main transformer capsule air pressure monitoring, in particular to a main transformer capsule inflation pressure measuring and pressure relieving device.
Background
Under the condition of the whole tightness test, the capsule in the main transformer oil conservator needs to be inflated to ensure that the internal pressure of the capsule reaches 20-30 kpa, as shown in fig. 1 in the prior art, the oil conservator is very high, so that the air duct 1 is led to the ground for connecting an air pump, and a first valve 2 and a first pressure gauge 3 are sequentially arranged on the air duct 1 from bottom to top at the height convenient for manual operation and observation. During inflation, the pressure value of the first pressure gauge 3 can be observed while the inflation is performed; however, in the actual use process, the air pressure from the air pump is large, and the air duct 1 is thin, so that the pressure at the first pressure gauge 3 is larger than the pressure in the capsule in the actual use process, and the value displayed by the first pressure gauge 3 is larger than the value of the pressure in the capsule. If the accurate pressure value in the capsule is to be detected, the air pump is closed, the first valve is closed, and after the value of the first pressure gauge 3 is stable, the accurate air pressure in the capsule is obtained. There are two problems with doing so: 1. stopping to detect the air pressure; 2. the air pressure in the capsule can not be known in time, and overcharge is easy to occur.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a main transformer capsule inflation pressure measuring and relieving device which can detect the pressure in a capsule in real time during inflation.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a main capsule of becoming is inflated pressure measurement and pressure relief device, includes the air duct with capsule intercommunication, is equipped with first valve and first manometer by supreme in proper order down in the lower part of air duct, its characterized in that: the lower end of the air duct is connected with a three-way pipe, and one end of the three-way pipe is connected with a detection pipe;
and a second pressure gauge and a second valve are sequentially arranged on the detection tube from the three-way pipe to the direction of the mouth of the detection tube.
Preferably, the other end of the three-way pipe is used for being connected with an air pump.
Preferably, the free end of the detection tube is in communication with the atmosphere.
The utility model provides a main transformer capsule inflation pressure measuring and pressure releasing device which can detect accurate air pressure in a capsule at a detection tube, does not need to stop inflation and can release pressure in time through the detection tube.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic diagram of a prior art structure;
fig. 2 is a schematic structural view of the present utility model.
Detailed Description
As shown in fig. 2, the main transformer capsule inflation pressure measuring and relieving device comprises an air duct 1 communicated with a capsule, wherein a first valve 2 and a first pressure gauge 3 are sequentially arranged at the lower part of the air duct 1 from bottom to top, the lower end of the air duct 1 is connected with a three-way pipe 4, and one end of the three-way pipe 4 is connected with a detection pipe 5;
and a second pressure gauge 6 and a second valve 7 are sequentially arranged on the detection tube 5 from the three-way tube to the direction of the mouth of the detection tube.
Preferably, the other end of the tee pipe 4 is used for being connected with an air pump. The air pump is connected with the local end for inflation.
Preferably, the free end of the detection tube 5 is in communication with the atmosphere. When the air is inflated and over-pressure is generated, the second valve is opened, and the pressure is relieved by the local end.
When the capsule is inflated, the air pump is connected to the lower end of the three-way pipe 4, the first valve 2 is opened, the second valve 7 is closed, the air is inflated, the first pressure gauge 3 displays the air pressure in the air duct 1, the air pressure displayed by the second pressure gauge 6 is the air pressure in the capsule, and the air pressure detection is unnecessary to stop inflation. If an overcharge condition occurs, the second valve 7 can be directly opened for pressure relief.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
