Description
Technical Field

Background
In the existing transformer oil chromatography on-line monitoring device, gas separated from oil is usually carried into a sampling port by carrier gas, and then enters a chromatographic column, and finally the content value of each gas is measured. Therefore, the normal output of the carrier gas is the key for ensuring the successful determination of the gas components in the oil, and the pressure of the carrier gas cylinder is also the key concern during manual inspection. When the pressure of the gas carrying bottle does not meet the requirement, the gas carrying bottle is replaced manually. The gas-carrying cylinder has large volume and heavy weight, which brings great inconvenience to storage, transportation and replacement. Particularly, for economy, a certain number of empty bottles are accumulated and then are uniformly charged to a manufacturer for secondary inflation, and the accumulated empty bottles cause waste of warehouse space. If the air-carrying bottle is replaced by the related personnel, but the air bottles are not classified and stored in the warehouse according to the standard, and the air-carrying bottles are uniform in specification and size, and the later-stage air bottles can be known to be used only by sequentially checking the pressure gauge. In addition, compared with the common scheme of replacing the gas carrying bottle, the gas carrying generating device is adopted in the online oil chromatography monitoring device of some manufacturers to provide carrier gas, although the gas carrying bottle is not required to be replaced, the step of generating the carrier gas is complicated, the complexity of the system is increased, higher technical difficulty is brought to the maintenance of the whole system, and the device cost is too expensive.

Further, one side of the two halves of the fixing cover 203 may be connected through the hinge 209, the other side of the fixing cover may be connected through the fixing device 205, and the fixing device 205 may be fixed to the fixing groove installed on the side of the other half of the fixing cover 203 through a buckle installed on the side of the half of the fixing cover 203.
Further, the controller 204 may be configured to access a communication module of the oil chromatography online monitoring device, and is configured to transmit the internal pressure information and the gas concentration information of the deformable gas carrier cylinder 1 acquired by the pressure sensor 109 and the gas concentration sensor 110 to a background, so as to facilitate monitoring of the gas carrier cylinder information and reduce the labor operation and maintenance cost. The pressure sensor 109 and the gas concentration sensor 110 arranged in the inner container shell transmit pressure value and concentration value information in a Bluetooth or wireless mode.
The working process of the invention is as follows: the base 201 is installed in an oil chromatography on-line monitoring device operation cabinet of a transformer substation site, when carrier gas is replaced, a buckle on the fixed encloser 203 is firstly opened, the fixed encloser is taken down, and a compressed gas carrier bottle which is wrapped and fixed by a gas carrier bottle shell is taken out. An inner concave ring gear 207 at the bottom of the outer shell 105 at the bottom of the replaced gas carrier bottle is inserted after being aligned with a gear at the top end of the rotary telescopic mechanism 202 on the base, and an inner ring of a deep groove ball bearing in a cylindrical groove 108 at the bottom 103 of the inner container of a new deformable gas carrier bottle 1 filled with carrier gas is inserted into a cylindrical projection 114 in the outer shell 105 at the bottom. The position of the blocking projection 208 on the upper part of the fixed cover 203 is adjusted to the position corresponding to the blocking groove 115 on the shell 104 on the upper part of the gas-carrying cylinder, then the lower part of the fixed cover 203 is inserted into the annular groove on the base 201, the two halves of the fixed cover are closed, and the clip-shaped buckle on one side of the fixing device 205 is buckled on the fixing groove on the other side to be fixed, namely the replacement is finished.
After the device is replaced, soapy water is coated on a joint where an air outlet nut of the gas-carrying cylinder is connected with equipment, whether bubbles are generated or not is carefully checked, whether the joint leaks air or not is confirmed when the gas-carrying cylinder is installed and replaced, if no bubbles are generated at the joint, the gas-carrying cylinder is indicated to be airtight, and the device can be normally used. And finally, debugging the connection between the sensor and the system to ensure that the device is connected with the background and has no abnormity.
The requirement of the oil chromatogram on-line monitoring device for the carrier gas pressure is between 0.4Mpa and 0.45Mpa, the sensor inside the gas cylinder feeds back an internal pressure signal in real time, along with the use of the carrier gas, the pressure output by the carrier gas cylinder is smaller and smaller, the controller 204 can control the rotary telescopic mechanism 2 to generate a longitudinal upward thrust for the gas cylinder according to the consumption condition of the actual carrier gas, all the stress acts on a deformation structure, thereby compressing the volume of the gas cylinder, increasing the internal pressure, enabling the pressure to be within the range required by external equipment, and achieving the purpose of maintaining the internal pressure and the volume of the compressed gas cylinder.
The replaced deformable carrier gas bottle 1 is stored in a warehouse, can be distinguished from the carrier gas bottle which is not used in terms of volume, and the compressed carrier gas bottle has reduced volume, thereby being convenient for storage and transportation; simultaneously this application is equipped with baroceptor, can realize the pressure information of teletransmission collection, consequently also can be under the circumstances of non-closely, realize carrying the gas cylinder through looking over the pressure value and have or not carry the gas to distinguish.
While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
