Four Practical Ways For High Voltage Switchgear Daily Maintenance



KYN28A-12 switchgear 2


High voltage switchgear has good performance to gain a long life time, like anti-corrosion, anti-aging etc characteristics. Usually the cabinet is with high strength design, the material mainly selects insulation DMC material, which is safe, durable and strong flame retardant. The delicate workmanship, perfect detail design and easy operation are some of its strong advantages. If the HV switchgear could be maintained in right ways, it could last longer.


Following we would like to introduce 4 ways for daily maintenance of high voltage switchgear:

1. Regular dust cleaning

To make sure the operation of equipment and electrical circuit safety, we should do daily regular dust cleaning of the high voltage switchgear, and record the maintenance data to avoid the the dust accumulation affect the work performance.


2. Checking if the bolt tightening or not

As the HV switchgear plays an important role in power distribution etc, ensure its normal operation is necessary, checking bolt fastening routinely in case the bolt is loose, timely tight it via professional tools if happened. What’s more, pay attention that whether the switchgear cabinet overheating or discharge traces.


3. Checking the lighting situation

Checking if the lighting device intact or not, any problems feedback and repair to the related people timely. Tips from high voltage switchgear manufacturers that: as the electrical switchgear is involved in lots of principles, it must be professionals who operate and repair, especially for internal maintenance non-professionals do not try.


4. Replacement of damaged parts timely. (must be handled by professional)

I suggest that the company allocate professional managers of high voltage switchgear, who has rich knowledge and experience in electrical field, to deal with the issues timely to avoid leading to safety issues when the power distribution cabinet are damaged or need to be replaced.

In addition to above 4 points, it should also check the grounding of high voltage switchgear in the routine maintenance and usage. The operation people must know the internal circuit, electrical knowledge and the switchgear structure well. And there may be slightly difference in the internal structure of different HV switchgears, you need to read the product description carefully before operation to avoid potential safety problems.
