Precheck before putting it into use.Check id packing is in good condition. Check the appearance of vacuum interrupter andWhether it corresponds to the test certificate after uppacking. When shaking the interrupter, the ceramic envelop should be integrated. Power frequency withstand voltage should be tested before operating vacuum interrupter. Clean the surface with a dry colth or alcohol damped cloth before testing. The normal way for testing is an follows: when in the clearance between open contacts applies with 70 percent of rated power frequency withstand voltage within 1 min. The vacuum interrupter will be qualified if there is no sudden change and trip phenomena in the pointer of the vacuum interrupter. 2. Mounting of vacuum interrupter a. Clean the surface of vacuum interrupter with cotton or alcohol dipped silk cloth before mounting. Meanwhile clean the conducting pole and surface of electric connection in order that the vacuum interrupter can have good electric contact with the equipment.   b. The interrupter should be adjusted in the line with the equipment after mounting. The mechanical date related to the interrupter must meet the given specification.  3. In mounting, attention should be paid to the following:    a. When operating, guide unite unit must be provided for the interrupter. The coaxality of moving conducting pole and axial line of interrupter must meet the requirement. There should not be torque force applied on the bellow.   b. When mounting, it is forbidden to beat or strike the interrupte
