Water heater transformer is a kind of power equipment that converts voltage and current according to the law of electromagnetic induction. In the process of transmission and distribution, transformers must be used for step-up and step-down to reduce losses in the transmission process. As a result, plants and businesses use electricity connected10kvThe power supply is converted into low-voltage power through a transformer. Today, the editor will introduce several detection methods for transformer installation.
What are the detection methods for transformer installation?
1.Inspection method for visual inspection of transformer
The visual inspection method is to observe the appearance changes of the visible part of the operating equipment with the naked eye to find abnormal phenomena of the equipment, such as discoloration, deformation, displacement, cracking, loosening, fire and smoke, oil leakage, Broken and broken wires. Visual inspection can be used to check for signs of flashover, adhesion of foreign objects, corrosion and contamination. Therefore, visual inspection is one of the most commonly used methods in equipment inspection.
2.Method of Detecting Smelly of the Nose by Transformer
Once the insulation material of electrical equipment is overheated, it will produce peculiar smell in the surrounding air. This particular smell can be smelled by ordinary inspectors. When you smell this peculiar smell during the normal inspection, you should carefully check and observe the overheated equipment and parts until you find the cause.
3.Method of detecting transformer by hand touch
Transformer manufacturers in Tibet prohibit the use of touch tests on live high-voltage equipment, such as transformers in operation and neutral grounding devices for arc suppression coils. For uncharged equipment, and the housing has been reliably grounded, you must touch and check the temperature or temperature rise by hand. The heating and vibration of the auxiliary equipment can be checked by hand.
4.Ear hearing method for transformer detection
The primary and secondary electromagnetic equipment of the substation (such as transformers, transformers, relays, contactors, etc.), after passing alternating current during normal operation, the winding core will emit"Buzz" sound, uniform rhythm and a certain loudness. The operator on duty of the Tibetan transformer manufacturer should be familiar with the characteristics of the sound. When the equipment fails, it will make noise and even make a "cracking" discharge sound. The device can be judged by the changes in rhythm and volume under normal and abnormal conditions. Occurrence and nature of failure.
