Transformer is a kind of power equipment

Transformer is a kind of power equipment that transforms voltage and current according to the law of electromagnetic induction. In the process of power transmission and distribution, it is necessary to boost and step-down voltage through the transformer to reduce the loss in the process of electric energy transmission.  Therefore, power supply of factories and enterprises is connected to 10KV power supply, which is converted into low-voltage electric energy by transformer.  Xizang transformer manufacturers today to introduce a transformer installation transformer several detection methods  

First, transformer detection visual method  

Visual method is that the personnel on duty with naked eyes to observe the appearance changes of the visible parts of the operating equipment to find abnormal phenomena of the equipment, such as discoloration, deformation, displacement, rupture, loosening, smoke, oil leakage, broken strands and wires, flashover traces, foreign body hanging, corrosion and filth can be checked out by visual method.  Therefore, visual inspection is one of the most commonly used methods of equipment inspection.  

What are the detection methods of transformer installation?  

Two, transformer detection nose sniffing method  

The insulation of electrical equipment can produce an odor in the surrounding air if it overheats.  The odor is detectable to regular inspectors.  When the smell of this peculiar smell in the normal inspection, should be carefully inspected and observed, found overheating equipment and parts, until the cause is identified.  

Three, transformer detection hand touch method  

Transformer manufacturers in Xizang are forbidden to use hand touch test for live high-voltage equipment, such as transformers in operation and neutral grounding devices of arc-suppression coiled coiled wires.  For the equipment without electrified and the shell is reliably grounded, it is necessary to touch and check its temperature or temperature rise by hand.  Heat and vibration of secondary equipment can be checked by hand touch method.  

Four, transformer detection ear listening method  

The primary and secondary electromagnetic equipment (such as transformers, transformers, relays, contactors, etc.) of the substation will emit "hum, hum" sound with uniform rhythm and certain loudness after normal operation through alternating current.  Xizang transformer manufacturers operating duty personnel should be familiar with the characteristics of the sound, when the equipment failure, there will be a noise, and even a "crack" discharge sound, can be normal and abnormal when the temperament, volume changes to judge the occurrence and nature of equipment failure.
