With the rapid development of power technology, high and low voltage switchgear has been basically unattended, but in order to ensure the long-term stability of power supply facilities, still need full-time electrician regular maintenance and repair, to ensure that the power distribution cabinet always maintain a good running state, so high and low voltage switchgear daily maintenance work what are the contents?

With the rapid development of power technology,High and low voltage switchgearUnattended operation has been basically realized, but in order to ensure the long-term stability of power supply for power facilities, full-time electricians are still required to carry out regular maintenance and overhaul to ensure that the power distribution cabinet is always in good operation. What are the contents of the daily maintenance of high and low voltage switchgear?

IntroductionHigh and low voltage switchgearInspection of preparatory work

Before installation, the supervision engineer and Party A's engineer shall check whether the access road is unblocked. If necessary, the general contractor shall be required to build a simple transportation channel to connect with each installation point. The construction site layout shall meet the requirements of safe and civilized construction. At the same time, the construction equipment arrangement of the installation unit shall be checked, and the installation unit shall be urged to check the construction equipment to ensure good condition. Before the high-voltage equipment arrives at the site, distribution room, trench, foundation channel steel shall be completely completed

1) Power distribution room

Before the construction of the power distribution room, the detailed drawings required for the construction of the power distribution room shall be submitted to the construction party (within 2 weeks after the signing of the contract, the focus shall be on the confirmation of the location, content and completion time of the drawings by the customer). And in the construction process of the power distribution room, we or the technical personnel of the cooperation unit should supervise on site to avoid construction errors. (The construction of power distribution room takes about 2 weeks)

2) Foundation

The installation position of the channel steel shall correspond to the equipment air duct reserved in the power distribution room, and the minimum distance between the equipment and the wall shall be clear (the distance is too close to open the cabinet door of the equipment). (The welding of the channel steel takes about 2 days, and our technicians must be on site to guide) The equipment arrives at the site:

3) If the power distribution room and foundation are not built, the equipment shall be stored (rainproof or necessary rainproof materials shall be provided).
