|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.|
* Check list of maintennance
|1||Busbar and insulator||Check whether there are sparking trace on the insulator’s porcelain.||Winding insulation is damaged or connection is poor.|
|Check the color at the connection part of the busbar.||
Insulator is damaged.
Insulator pollution is serious.
Abnormal discharge sound.
Connection part is over-heating
Operation voltage is 10% higher than the rated voltage
Operation current is 30% higher than the rated current.
|3||Apparatus, Signal, Indicator||No indication or the indication is not correct||Device is damaged.|
|4||Lightning Arrester||Crackle||Device is damaged. It should be replaced|
|Surface pollution||Too much dust on the surface.|
|Tilting, cable terminal or earthing terminal is loosing||Mounting is not firm.|
|5||Contactor||Too much noise||
The iron core top surface is not even.
There are pollutions on the surface.
|Over-heating, burning or abnormal smell from the contact.||
Imperfect cable connection.
The contactor was once burned-out under large current.
SF6 load switch
|The device does not conform to the factory specifications||SF6 gas leakage|
If possible, use infra-red gun to detect the temperature of various electric components. In case of temperature abnormality, solve the problem in time.
