Daily maintenance of plastic case circuit breaker is the basic work of equipment maintenance. It must be institutionalized and standardized. Regular maintenance of equipment should be formulated work quota and material consumption quota, and assessed according to the quota. Regular maintenance of plastic case circuit breakers should be included in the assessment content of the workshop contract responsibility system. Regular inspection of plastic case circuit breaker is a kind of planned preventive inspection. Besides human senses, there are also some inspection tools and instruments. Regular inspection is carried out according to the regular inspection of the truss cards. Regular inspection of the truss is also called regular spot inspection. The accuracy of mechanical equipment should also be checked to determine the actual accuracy of the equipment. Maintenance of plastic case circuit breaker should be carried out according to maintenance rules. Equipment maintenance rules are the requirements and regulations for the daily maintenance of equipment. Persisting in the implementation of equipment maintenance rules can prolong the service life of equipment and ensure safe and comfortable working environment. Its main contents should include:

(1) The location, method and standard of routine maintenance and regular inspection of tendons;

(2) Moulded case circuit breakers should be neat, clean, firm, lubricated, anticorrosive, safe and so on. The contents, methods, tools and materials used, the standards reached and matters needing attention are as follows:

Once the circuit breaker is used in a special environment, it should be replaced in time to avoid affecting the normal use.

(3) Contents and methods of examining and evaluating the maintenance level of equipment for operators.

Maintenance requirements for plastic case circuit breakers:

(1) Plastic case circuit breakers must be installed in strict accordance with the specifications:

It is also the best maintenance for a product whether the use method of plastic case circuit breaker is correct according to the fixed method of the manufacturer. The wrong use method not only fails to give full play to the performance of the equipment, but also causes damage to the equipment frequently when the equipment is running.

(2) Enterprises with plastic case circuit breakers (constant temperature, constant humidity, shock proof and dust proof) which have special requirements for the environment should take corresponding measures to ensure the accuracy performance of the equipment;

(3) Plastic case circuit breakers are not allowed to disassemble parts in daily maintenance, stop immediately when abnormal conditions are found, and do not allow diseased operation;

(4) Strictly implement the cutting specifications stipulated in the Instructions of Equipment and allow only the finishing of parts for direct use:

Processing allowance should be as small as possible. When processing castings, the rough surface should be sandblasted or painted beforehand.

(5) Non-working hours should be covered with protective cover, long-term rest, regular wiping, lubrication and empty operation;

(6) Appendices and special tools shall be shelved on special shelves, kept clean, prevented from grinding and shall not be lent out;

(7) In the daily use of plastic case circuit breakers, it is absolutely not easy to disassemble the equipment, which may cause parts to be damaged or other substances to enter:

If any abnormality occurs in the use of equipment, it is necessary to stop running in time and check to remove the fault and then continue running. Never try to continue running in the state of failure.
