What is a 3200 kVA Transformer?

3200kva transformer 1

3200 kVA Transformer is a kind of Low Tension Current Transformer .

If the primary current via the Low Tension Current Transformer exceeds the CT’s nominal rating, the CT is saturated. Due to a deterioration in CT’s linearity on both the primary and secondary sides, errors rise. The higher the load, the greater the saturation of the CT.

When an overload develops on the primary side of a current transformer, the two types behave differently.

 When the primary current is overloaded, the CT measurement becomes saturated. Until there is a very high primary current, the protective Low Tension Current.

 

The 3200 kVA Transformer will not saturate on the secondary side to protect the equipment.

Moreover, protective transformers with a Class 5P15 accuracy rating imply that the primary current does not become saturated until the Low Tension Current

3200 kVA Transformer’s nominal power rating is exceeded by 15 times.

The Safety Factor parameter in transformer measurements reflects the primary side current’s excessive amperage compared to the secondary side measurement device’s current.

3200 kVA Transformer: Notes on Use

3200 kva transformers 1

If the primary current is insufficient, we can increase accuracy and output by adding primary winding. Still, the rated turns ratio must remain constant. For example, if the primary current is 50A, we can use a 100/5A Current.
The primary current can be turned twice to maintain the same turns (1:50 = 2:100) ratio as before.
Please be reminded that personal safety might be jeopardized by improper selection, installation, or operation. Don’t open the secondary circuit if the primary circuit already supplies power. High voltage can be generated, putting your safety at risk.
In testing, because of the low resistance of the current transformer, the secondary winding can be operated as a short circuit.
Otherwise, significant voltage is generated, which might be hazardous when in use.
A current 3200 kVA Transformer’s secondary cable must be considered while selecting a transformer. To avoid exceeding the CT’s available VA, the total cable load must be added to the equipment burden.
Hence, P1 (K) must face the supply feeder, and P2 (L) face the load while installing these components.
Secondary connections must also be constructed in line with instrument schematics and the primary connections.
A dangerously high voltage could be present if the CT’s secondary terminals were open-circuited on load. In most cases, it is good to earth one of the secondary windings.

3200 kVA Transformer: Construction and Design 

Magnetic core, primary and secondary windings, and an insulated body make up the Low Tension Current Transformer.
An annealed, varnished silicon steel core is insulated with polycarbonate core caps.
High precision semi-automatic machinery is used to wind the secondary winding into a toroidal configuration. 
The PEW coated windings are then covered with elephantitis paper, varnished, and double-tapped with PVS tapes for the tape wound ring-type current 3200 kVA Transformer.
The windings of an encapsulated type current transformer are protected from damage by a heat-resistant split cap that surrounds them.

Features of 4000 kVA Transformer

4000 kva transformer 1

First, using a computer program, it is possible to determine precisely how winding electric field graduates are distributed and then ensure that the helical structure can satisfy the impulse under high voltage. The transformer’s insulating structure is studied and calculated to ensure that the products are safe to use. By estimating magnetic leakage and temperature fields, the design demand may be easily met. Lamination design optimization reduces magnetic distortion in the gap and improves no-load performance.
Next, a high-quality grain-oriented cold-rolled silicon-steel sheet is used for the iron core. It is cut using a specialized shearing machine, leaving only a tiny burr.
Multi-steps and 45lll-leaning joints reduce no-load loss, no-load current, and noise. Using a board-like construction, the core clamping device can produce a lot of force. Make sure the 4000 kva transformer axis cushioning blocks enough pressure by fastening nails.
Then, stability and uniformity were achieved by winding the inner coil directly on an insulating barrel, then adding chamfering spacers and padding blocks.
To ensure the windings were placed in the correct axial position, BDK-80M synchronized lifting equipment was used throughout the assembly.
Moreover, due to its wider width and higher mechanical strength, wide-width steel plates are used to reduce the number of welds needed on tanks with flat roofs or folded plate types. In addition, the tank and pipes may be used for a long time without leakage, thanks to advanced welding techniques and groove-type flanges.
A comprehensive plate radiation system with heavy-duty blowers produces minimal noise to raise the heat dissipation center, reduce the number of radiating plates, and prevent leakage.
It can be attached to the 4000 kva transformerr directly. The oil that has been implanted under vacuum and strengthened by capsule-type conservators can be delayed from aging successfully.
In addition, Pt100 thermal resistors are commonly used. A pressure relief valve with contacts is installed on top of the tank, a vacuum relay on the Conservator, and a tank-mounted oil pressure indicator with connections.
All of these gears can be used to convert and transfer signals. LV and HV bushings are pollution retardant porcelain oil types, which may extend the insulation area and be used in high pollution conditions. Stainless steel is used for the padding plates and terminal case to give them an exquisite appearance.
Daelim 4000 kVA Transformer products for the Chinese market continue to be introduced based on world-class professional technology and management know-how.
Our goal is to make a more substantial contribution to the revival of national industry and the growth of the social economy by increasing our investment in research and technology. When it comes to China’s economic reform and development, our company has achieved great strides.
