In tarkabirWhat are the manufacturers of oil immersed transformersWhat is the performance category

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, damage to machinery and equipment, etc.

In tarkabir.The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.

The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.

What about oil immersed transformer fire?

Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.

In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.

Noise pollution control and prevention measures of dry-type transformer

Quality department.When the screw of the through core extruder holding the iron core of the transformer is loose,In tarkabirParameters of 500 KVA oil immersed transformer, there are screw cap parts left on the iron core, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer,In tarkabirOil type transformer structure, and can be solved until power failure.

Noise dispersion of dry-type transformer

Difference between dry-type transformer and oil immersed transformer:

Wiring mode of dry-type transformer:

Quotation sheet.Protective measures for damping of dry-type transformer

Right, as & ldquo; Great Lars car & rdquo;, After replacing one 255kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table 1. Table 1 evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.

Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).

In tarkabir.Falling foreign matters and piercing

Naturally, if the oil immersed transformer catches fire,In tarkabirPrice list of power transformer, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

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).
