FAQ

Application and Attention

1. Precheck before putting it into use.

Check id packing is in good condition. Check the appearance of vacuum interrupter and

Whether 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 interrupter envelop with hard things in case crack may occur to cause air leakage.

c. Take care to assure that the conducting pole must be coaxial with interrupter, and that the conducting pole must be vertical on the face of fixed end

d. Take care not to disassemble the interrupter repeatedly to prevent screw from slipping. There should not be twisting on the moving conducting pole and over press on bellow to avoid that any torque force and scratch may occur to bellow to reduce its service life.

e. During mounting, the force applied on the face of both ends should not go beyond the static relief pressure stipulated in the specification.

4. Application.

a. Check the vacuum interrupter periodically by the way power frequency withstand voltage. For this, please see subclause

b. Periodically check how burnout is going on for contacts. When it comes to the burnout mark of moving conducting pole, it shows that the vacuum interrupter has finished its electrical endurance, and it should be replaced.
