Daily maintenance and regular maintenance of water conservancy machinery and equipment
Daily maintenance:
It is a regular work, and the operation duty person is responsible for regular maintenance and dust cleaning of the equipment. Routine maintenance should check the operating status, keep the equipment and environment hygienic and clean, and ensure that the transmission parts are lubricated as required.
Regular maintenance:
It is a phased work, which is the responsibility of maintenance personnel and is carried out every year 1~2 professional inspections, cleaning, repairs and testing. Preventive tests on electrical equipment (including power cables) can be conducted once every 1～3 years for relay protection equipment. The calibration of the device should be carried out once a year, the inspection of the grounding device and the grounding resistance value should be carried out every spring, and the arrester should be inspected and tested every year. Regular maintenance should include regular inspections of facilities (including inspections), timely repairs or planned repairs for abnormal situations, and prevent damage or failure of facilities. Comprehensive and mandatory inspection and renovation of relevant facilities should be included in the annual plan every year.

Major repair:
Maintenance work that restores the original technical status of the equipment is the responsibility of professional maintenance personnel. Major repairs (restorative repairs) should be carried out in a planned manner after the facilities have been in operation for a long time. Comprehensive renovation and repair or replacement of important components to restore the facility to good technical condition should comply with the following regulations:
⑴ Various types of pump equipment can set their own overhaul cycle standards.
⑵The motor should be overhauled at the same time as the main engine.
⑶The transformer overhaul cycle should be determined based on analysis of preventive test results over the years. 35KV and above should be overhauled once after 5 years of operation, and every 5～Every 10 years; 10KV and below can be overhauled every 10It will be overhauled every year or so.
(4) The overhaul cycle of power distribution equipment should be determined based on the defects of the switch and the actual operating conditions. Newly put into operation high-voltage circuit breakers should be overhauled after one year of operation. From then on, circuit breakers of 35KV and above should be overhauled every5 Overhaul once a year, 3~10KV distribution system circuit breaker should be carried out every 1 ～3Overhaul once a year, 3～ 10KVThe circuit breaker for the starter motor should be overhauled once a year. If the brake fails 3 times or it sprays fuel or smoke seriously, it should be disassembled and inspected.
⑸The overhaul period of high-voltage overhead lines should be determined based on their intactness and whether their electrical and mechanical properties comply with relevant regulations.
