Noise dispersion of dry-type transformer
Venitsya.Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.
The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore,VenitsyaRecovery of transformer cabinet, the hanging core of dry-type transformer should be carried out according to the above matters, the load can be connected.
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, the dispersion spacing and adverse effects are very large.
The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
At that time only a few companies in China could produce 500kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut),VenitsyaPower transformer ranking, wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying,VenitsyaHow much is 500KVA box transformer, the treatment goal can be achieved.
Process inspection.Noise solution of dry-type transformer
Difference between dry-type transformer and oil immersed transformer:
The key reason for oil leakage is that there are defects in cast iron parts
The whole process of hanging the core of dry-type transformer is more critical and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!
Price.Solenoid insulation deterioration
Protection mode for type selection of dry-type test transformer
The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
