This gas injection device comprises the first injection tube and the second injection tube, and the first injection tube and the second injection tube have piston component to drive, thus carry out gas production operation by the first pipeline and extract Balance Air from origin, and carry out gas injection operation by the second pipeline and Balance Air is injected insulating oil container.Apply technical scheme of the present invention, testing crew can realize the automation mechanized operation extracting Balance Air and injection balance gas in the process of test, thus utilize robotization of the present invention gas injection device realize quantitatively, gas production rapidly, gas injection operation, ensure that the accuracy of test findings, and improve the work efficiency of experiment work.
In the present embodiment, the volume of the first injection tube 10 is equal with the volume of the second injection tube 20.
Particularly, gas injection device also comprises: the first T-valve 12, first injection tube 10 is communicated with the first interface of the first T-valve 12, source of the gas 200 passes through the second orifice of the first pipeline 11 and the first T-valve 12, and insulating oil container passes through the 3rd orifice of the second pipeline 50 and the first T-valve 12.Gas injection device also comprises: the second T-valve 22, second injection tube 20 is communicated with the first interface of the second T-valve 22, and source of the gas 200 is connected with the second interface of the second T-valve 22 by the 3rd pipeline, the 3rd orifice of blowdown piping 60 and the second T-valve 22.Preferably, the first T-valve 12 and the second T-valve 22 are solenoid valve.
Be illustrated in figure 1 this gas injection device and be in original state.Now, the firstth T-valve 12 and the second T-valve 22 circuit connection state is controlled as shown in Figure 2.Power supply 100 provides electric energy to whole control circuit.In an initial condition, must ensure that power control switch 101 is in off-state, control switch 102 and be positioned at E position, all the other gauge tap then do not do requirement, namely the switch controlling the first T-valve 12 on the first pipeline 11 can be in A position, also can be in B position, in the same manner, the switch controlling the second T-valve 22 on the second pipeline 50 can be in C position, also can be in D position.
Particularly, the outlet of source of the gas 200 is connected with gas-carrier pipeline 40, and one end away from source of the gas 200 of gas-carrier pipeline 40 is all connected with the first pipeline 11 and the 3rd pipeline 21.Gas-carrier pipeline 40 is provided with for conducting or the carrier gas stop valve 41 cutting off gas-carrier pipeline 40.
As shown in Figure 3, when gas filling device carries out gas production operation time, staff is by the first interface of the first T-valve 12 and the second orifice, namely the circuit that staff controls as shown in Figure 4 connects, power control switch 101 is closed, then the switch of control first T-valve 12 is made can be in A position, thus source of the gas is communicated with the first injection tube 10, and by the first interface of the second T-valve 22 and the second orifice, namely staff makes the switch of control second T-valve 22 be in D position, thus is communicated with blowdown piping 60 by the second injection tube 20.Then, staff opens the carrier gas stop valve 41 in gas-carrier pipeline 40, to carry out getting gas operation.Piston component 30 injection that first piston body is positioned at the first injection tube 10 is in an initial condition located most, and the second piston body is positioned at the tube port position of the second injection tube.After carrier gas stop valve 41 is opened, first piston body moves from left to right under the gaseous tension of source of the gas 200.When getting after gas completes, now, first piston body is positioned at the tube port position of the first injection tube 10, and the second piston body then moves to the injection port place of the second injection tube 20.Get after gas completes, the switch of control first T-valve is made to be in B position as shown in Figure 5, power control switch 101 keeps closing, the switch controlling the second T-valve is in D position, and staff closes carrier gas stop valve 41, like this, the Balance Air nitrogen in source of the gas 200 just stops in injection first injection tube 10.
As shown in Figure 6 and Figure 7, Fig. 7 shows the first the circuit connection structure schematic diagram corresponding to gas injection operation, and staff carries out gas injection operation to Balance Air.Staff makes power control switch 101 be kept closed, and the switch controlling the first T-valve remains on B position, and the switch controlling the second T-valve remains on D position, and at this moment, the control switch 102 in circuit is transformed into F position.Like this, the first injection tube 10 and insulating oil reservoir, the second injection is with being communicated with source of the gas 200.When after unlatching carrier gas stop valve 41, Balance Air in first injection tube 10 is injected insulating oil container by the second piston body under the promotion of Balance Air pressure, to displace methane, ethene, ethane, acetylene, carbon monoxide, the wherein gas such as carbon dioxide and hydrogen of dissolved in insulating oil, thus stratographic analysis is carried out to these gas application vibration degassing method, and then the Hidden fault of analytical equipment.
Similarly, as shown in Figure 8, Fig. 8 show corresponding to gas injection operation second in control circui schematic diagram, when carrying out gas injection, staff can also make the switch of control first T-valve 12 be in A position, and rest switch is all identical with the first circuit connecting mode.Such control circui, can make the first injection tube 10 and insulating oil reservoir equally, and source of the gas 200 is communicated with the second injection tube 20, thus staff opens carrier gas stop valve 41 carries out gas injection operation.
As shown in Figure 9, after gas injection has operated, retentive control switch 102 has been positioned at F position, and the switch controlling the first T-valve 12 can be in A position, and the switch controlling the second T-valve 22 is in D position.Like this, carrier gas stop valve 41 cuts out by staff, thus stops gas injection operation.
As shown in Figure 10, power control switch 101 is kept to close, and control switch 102 is positioned at E position, the switch controlling the first T-valve 12 is in A position, the switch controlling the second T-valve 22 is in C position, like this, as long as the switch of control second T-valve 22 is in D position by staff again, just become the circuit control structure carrying out getting gas operation.
In the present embodiment, one end away from source of the gas 200 of gas-carrier pipeline 40 is connected with three-way connection, and the first pipeline 11 is all communicated with three-way connection with the 3rd pipeline 21.
According to the another aspect that this law is bright, the invention provides a kind of inflating method of insulating oil container, employ above-mentioned gas injection device, inflating method comprises the following steps:
Step S1: be communicated with source of the gas 200 by the first injection tube 10, is communicated with the second injection tube 20 with blowdown piping 60;
Step S2: open source of the gas 200 and carry out gas production operation to make the first injection tube 10;
Step S3: be communicated with the second pipeline 50 by the first injection tube 10, is communicated with the second injection tube 20 with gas-carrier pipeline 40;
