Features & Advantages
1. Low loss, low noise and high reliability.
2. Excellent dynamic thermal stability and high over-load capacity.
3. Simulation analysis was carried out for the core mould design, thus to greatly reduce noise level. Simulated lightning impulse wave process was carried out for HV winding mould design, thus to greatly improve product's anti-lightning impulse capability.


After the circuit-breaker is switched off, please check the equipment in the following respects:

  1. Check the conditions of upper and lower contactors. Check the screw and nuts. Check the insulation part.
  2. Check whether there is any short-circuit within the arc extinguish chamber.
  3. Check the magnetic-trip armature.

Notices when checking instrument transformer:


During operation, please ensure the secondary circuit should have no short-circuit. If there is short-circuit at the secondary circuit, large short-circuit current is generated, which may damage the transformer or causes explosions. The secondary circuit should not be open circuit. Otherwise high-voltage may be generated, which may endanger the safety of both the equipment and operation personnel. Because the iron core may also burn out the instrument transformer. Therefore, before operating on the secondary circuit, please short circuit the secondary circuit terminal.


Capacitor fault processing:


First switch off the switch before the capacitor and make discharging for the capacitor group. Considering the capacitor may not be fully discharged and there are still residual current, the operating personnel must put on insulation gloves. Then, make short circuit between the two polarities of the capacitor and discharge the residual current. Then, dismantle and replace the capacitor.
