Why regular physical examination on time? In order to ensure physical and mental health, then our high and low pressure metal meter box is necessary to protect and maintain, so as to ensure that the high and low pressure metal meter box can be satisfied with all normal operation, in addition, to ensure the safety of anyone's life, so as to prevent the tragic harm. The maintenance of high and low pressure metal meter boxes is not in a mess. In order to ensure that there is no negligence, our maintenance operators are in accordance with the professional repair and inspection process, which not only ensures the quality of the operation, but also saves time. The following is about how to maintain the high and low voltage metal watch boxes with professional skills. In summary, there are five points as follows:

The first step: the inspection is to isolate the switch, keep the insulation layer clean and tidy, remove the surface stains, and check whether the insulator is charged or discharged. It is necessary to bond the iron fittings and porcelain parts and pass the grounding resistance. Later, check the lubrication condition of mechanical equipment and transmission parts. Whether the circuit breaker is intact or not, the appearance of wood and turbidity, the static and dynamic circuit breakers are necessary to be inseparable, the spring yellow operation pressure is uniform, in line with the requirements of the manufacturer, coated with a layer of glycerin or conductive paste. Re check that the opening distance of the circuit breaker meets the requirements of the manufacturer. It is necessary for three phases to be out of date. Finally, see whether the notes of high and low pressure metal meter box are intact.

The second step: that is to say, for the inspection of high-voltage circuit breaker, different barrier switch inspection new project is not the same, the practical operation is necessary to refer to the use of good machinery and equipment instructions.

The third step: that is to say, remove the neat cabinet door and inspect whether the five prevention locking equipment is intact.

Step 4: repair and tighten the connection screws of bus duct, and measure the insulation layer of bus duct.

Step 5: clean and tidy on the spot. If there are wooden or negligent items inside the metal watch box, it is necessary to inspect and make sure whether the special tools and the remaining raw materials are complete, and finally apply for the completion of the completed procedures.
