Stainless Steel housing /enclosure is widely used in residential communities, commercial centers, light stations, airports, factories and mines, enterprises, hospitals, schools and other places.

Stainless Steel housing /enclosure is widely used in residential communities, commercial centers, light stations, airports, factories and mines, enterprises, hospitals, schools and other places. Because it is a combined housing of various electrical equipment, and the maintenance of power facilities is the most important, the maintenance of Stainless Steel housing /enclosure is very important. The routine maintenance steps of Stainless Steel housing /enclosure are:

Stainless Steel housing /enclosure

1. Put the spare transformer into use, use the Stainless Steel housing/enclosure with the low-voltage side circuit breaker disconnected for maintenance, remove the operation and insurance of the power supply of the control system, and hang the "No Closing" sign on the switch handle.
2. Disconnect the circuit breaker on the high-voltage side of the transformer, close the grounding switch, fully discharge the transformer, lock the high-voltage cabinet, and hang a "No Switching" sign on the switch handle.
3. Check whether the grounding of the transformer is good, whether the ground wire is corroded, and replace it when the corrosion is serious.
4.Stainless Steel housing/enclosure maintenance, first clean the porcelain cover and housing, then check the housing, gasket, porcelain cover, non-application, discharge traces or rubber pads, cables and busbars are variable, cracks should be replaced.
5. Clean the dust around the Stainless Steel housing/enclosure and on the accessories, and check whether the fire safety facilities and ventilation management system design are normal.
6. Check that the contact surface of the busbar is kept clean, and the contact surface should be cleaned of oxide layer and coated with electric compound grease.
7. Tighten the lead terminals, pins, ground the screws, and use the screws as the bus bar. If there is any looseness, remove the screws, or file the contact surface with a fine flat file, or replace a spring washer or screw until Students have good contact with society.
8. Connect the low-voltage side circuit breaker to control the power supply operation insurance, and re-hang the "No closing" sign to prevent the loop back to the transformer.
9. Disconnect the grounding switch on the high-voltage side, lock the high-voltage switch bar, and measure the insulation resistance with a 2500v swing meter. The insulation resistance of Stainless Steel housing/enclosure shall not be lower than 70% of the original data when leaving the factory. If it does not meet the standards, it should be reported in time.
10. Turn off the grounding switch on the high-voltage side again to discharge the transformer.
11. Check the transformer room and transformer, as well as whether there are any remaining tools, and evacuate the construction site.
12. Disconnect the high-voltage side grounding switch, check the transformer site and the control line on the low-voltage side, correct the high-voltage side circuit breaker of the transformer, and let the transformer take off the high-voltage side mark.
13. Analyze in detail and make a record of the maintenance trial operation of Stainless Steel housing/enclosure.
