VCB Vacuum Circuit Breaker Interrupter Vacuity Degree Test Machine

HZ-KG7 Vacuum Interrupter Vacuity Degree Test for vacuum switchgear is the latest generation of products of my company, it is the upgrade product in the base of HZ-KG6 Vacuum Interrupter Vacuity Degree Test on the foundation of notion from the field user. HZ-KG7 Vacuum Interrupter Vacuity Degree Test has some features-higher measurement accuracy, better stability, more capacity.

Note

(1) Vacuum test should be carry out in the sunny and dry weather, the surface of the vacuum bubble must be wiped clean. If the vacuum bubble surface is contamination, it will induce vacuum leak, and seriously affect the actual test results of vacuum. In many test of the same vacuum tube, the time interval between two measurements must be not less than 10 minutes. Otherwise, the ionized air in the vacuum tube is no time to recover to normal, and it will lead test results to distortion.

(2) For vacuum testing of the same vacuum switch, we recommend no more than 3 times a day.

(3) Before vacuum testing, leak detection should be carried out, if leak detection is qualified, and then pass the quantitative test.

(4) Red cable connecting red cable clamps is the high voltage cable, black cable connecting black cable clamp is ordinary cables. In the actual wiring process, black cable don’t connect the high voltage output terminal in order to avoid test failure and a serious leak or threat to personal and equipment.

(5) Removal of the magnetic field voltage wires, with particular attention: firstly pull out the wires connecting equipment, respectively, followed after removal of all wires on the equipment, then removal of magnetic coils, or endanger the life, safety and equipment.

(6) Installing exciting coil, its orientation line must direct the middle of the joints of the interrupter arc chamber

(7) In the testing process, any part of body can not touch the high voltage output and magnetic field voltage output, the tester's base should be grounded.

(8) Test is completed, turn off the power; he high voltage output terminal touch ground and discharge to avoid electric shock by residual voltage of charged capacitor.

(9) Voltage wires of the magnetic field don’t short, or serious damage to equipment!

(10) Voltage wires and ion current wires must be separated!
