Transformer Oil Purifier Operation

ZJA High Vacuum High Voltage Transformer Oil Purifier is mainly for purify the transformer oil, removing water, gas and mechanical particles in the transformer oil. Also it can  pump out the non-corrosive gas in the container which Container’s volume ≤50m3  The ransformer oil water content can which under 50ppm,ransformer oil gas content under 10%, cleanliness less than 12 grade can be purifyied by ZJA transformer oil purifier. The opeartion power is 230V,60Hz, 3phase, 4wires/5wires.  

If have other power supply, please contact us for customized

ZJA High Vacuum High Voltage Transformer Oil Purifier Operation

Important Note

During the using process, the connecting bolt of binding posts will be easily loosened because of vibrating. Therefore, after the machine runs 600 hours or after each carry, user should fasten all the binding posts, otherwise, the joints will become loose easily, so the electrical appliances will be damaged easily, such as motor, heater and so on. Please kindly Observe.

Operate the electrical parts according to control panel 3.8

1. Preparatory work flow:

1.1 Install: Place the device steadily on a level surface.

1.2 Connect power cable:

1.2.1 Refer to the machine’s rated current value, using 100A O type copper connecting closed ring to rivet the cables 5 or 5*16mm2.

1.2.2 Connect the power and machine with the 3-phases 4 wire power lines.

1.2.3 Fasten all the binding posts inside the electrical control cabinet.

1.2.4 Rotate vacuum pump, roots pump and oil delivery pump ( If couldn’t rotate by hands then have a running test while on power).

1.2.5 Have electricity and check the phase order: Connect the power switch，connect the air switch, please check the light of “Phase order error”. It means working normally when the lighting is off, not vice versa.

1.2.6 Correct it when the phase order is wrong: Shut off the power and adjust any two phase lines of cable.

2.The filter operation of transformer oil(manual):

Set the rotary switch “manual/automatic” at the position “manual”, press the "Start" button switch. Please refer to the right picture about the manual/automatic operation diagram.

2.1 Valves status of oil inlet and outlet exchanging:

A in B out: V1.1，V5.2 open, V1.2,V5.1 closed; B in A out, V1.2, V5.1 open; V1.1, V5.2 closed.

2.2 Start vacuum pump:

First check the vacuum pump oil level, it should be between the two scales(or the middle of the sight glass)

Press the “Vacuum pump start” button, after that, press the “ Vacuum pump stop” button, repeated three times to observe the running performance of vacuum pump. The vacuum pump should run smoothly. The indicating light of starting vacuum pump is on while the vacuum pump is working and it will be off once the vacuum pump stop working.

2.3 Start roots pump:

Firstly check the oil tank level and the oil cup level of the roots pump. Please be sure that the level is between two scales (or observe the middle part of the observation mirror); Secondly when the vacuum gauge displays value below 4500Pa, please press the “starting roots pump” button and then the “stopping roots pump” button. Repeat it three times; Finally please observe the running performance of the roots pump and make sure it runs perfectly. The indicating light of starting roots pump is on while the roots pump is working.

2.4 Open the inlet and outlet valve:

When the vacuum gauge display value is less than 100Pa, open valve V1.1 and V5.2 according to the connection of the pipelines (Set A as inlet and B as outlet)

Note: Valve operation: closed while the handle clockwise rotation, and opened while counterclockwise; axis parallel to the handle position, the channel is fully open; handle position perpendicular to the axis, the channel is fully closed. The following operation of the valve described is the same with this. Please refer to the valves’ operation photo, see right photo:

2.5 Start oil outlet pump:

When the oil level in the vacuum separation chamber rises to the middle of the sight glass, press the "oil pump start" button, and then press the "oil pump stop" button, and observe the operation characteristics of the oil pump three times repeatedly, requiring the oil pump to run smoothly. When the oil pump is working, the indicator of the fuel pump start button will light. Adjust the "potentiometer" to change the frequency of the oil pump inverter, which is required between 15-25HZ.Please refer to the potentiometer adjust photo, see right.

2.6 Balance the liquid level of vacuum separation chamber

To observe the liquid level of the vacuum separation chamber, adjust the frequency of the oil outlet pump's transducer, required inlet oil amount slightly larger than the outlet oil amount is preferred.

2.7 Start heater

Close the heater knob (the closed position of the two-position knob is in the clockwise direction, the stop position is in the counterclockwise direction; the closed position of the three-position knob is in the clockwise or counterclockwise direction, and the stop position is in the vertical direction).

2.8 Adjust untreated oil’s temperature

Adjust the filtered temperature by referring to the instructions for use of the temperature controller. It is recommended to adjust the stop temperature to 60 ℃and the hysteresis temperature to 4℃.

2.9 Collecting oil samples:

After the temperature up to 60℃, and 3-5 times circulating filtration, please collect oil sample to check from the sampling valve till the treated transformer’s physicochemical indexes is qualified.

2.10 Valves State Under Normal Operation of the Machine

3. Normal shutdown operation of the machine(manual):

Disconnect heater  àClose the inlet oil valve V1.1 after 5 minutesàStop the roots pump  à Stop vacuum pump à Stop oil outlet pump when all the transformer oils inside of the vacuum separating chamber are deliveredà Close outlet oil valve V5.2à Disconnect the power switch à Disconnect the power switch  

4. The emergency stopping operation of the machine:

Press the emergency stopping button, disconnect the power air switch.
