What is the knowledge of electrical maintenance? The basics of electrical maintenance! The proper operation of electrical power as a core power component for all types of equipment is essential. In the event of electrical failure, a certain level of electrical maintenance can provide a timely solution to the problem and ensure the continued operation of the equipment. Some basic knowledge of electrical maintenance is presented below。
I. Type of energy disappearances
Electrical failure can be broadly classified as electrical failure and mechanical failure. In electrical failures, group failure is common, such as short circuits, break-ups, grounding, etc. Short circuits may be damaged by ageing insulation, leading to direct inter-group guidance; break-ups are usually due to fractures in the guidance lines; and on the ground, circuits are connected to the electrical shell. Mechanical malfunctions were mostly in the form of axle bearing wear, rotor cleaning, etc. The wear and tear of the bearings cause abnormal noise and vibration, while the rotor chamber frictions between the rotor and the fixed, which seriously affects the electrical performance. An initial determination of the type of failure can be made by listening to sound, observing the state of operation, etc。
Ii. Preparation of maintenance tools
Electrical maintenance requires a variety of tools. Test tools such as a universal meter are used to measure circuitary resistance and to determine whether there is a break or short circuit; a mega-eu scale can measure circuitary insulation resistance and check insulation performance. Dismantling tools include various types of wrench, rama, etc., which are used to remove parts such as electric caps, bearings, etc. In addition, welding tools, such as electric branding, are used to connect the conductor when repairing the circuit。
Iii. Elements for combat maintenance
If it is determined that it is a group failure, targeted maintenance is required. For short-circuit failure, local insulation can be repaired if the short-circuit point is visible; the entire circuit will need to be replaced if serious. When replacing the bypass group, the parameters of the original round group are accurately recorded, such as the number of the round, the line, the form of the rounding, etc., and are deformed to the original specifications. The detoxification is followed by insulation and increases the insulation performance of the detoxification group。
Iv. Axis replacement steps
When the bearings are worn, replacement is required in a timely manner. First, the old bearings were pulled from the upper axle by a rama, with care to avoid damage to the neck. After cleaning the neck, the new bearing is heated to a certain temperature so that it expands, and is then quickly placed on the axis, before the cooling shrinks. Upon completion of installation, an appropriate amount of lubricant shall be added to ensure good lubrication of the bearings。
