SCB13 dry type power transformer product features. Low loss: the no-load loss of the product is 20% lower than that of the SCB11 product, and the energy saving effect is excellent, running economy and maintenance free. Low noise: product noise level is 10 to 15 decibels lower than the current professional standard JB/ t10088-1999 "6-220kv transformer sound level". Low set: resin mixed materials adopt the most advanced mixing method in foreign countries and vacuum film degassing technology, so that the mixture is evenly mixed and the bubbles in the mixture are excluded. The product only has extremely low local discharge, can be controlled under 5PC. The high and low pressure coils are poured under vacuum and pressure, so that the resin insulation can be both encapsulated and inter-turn. The casting body has a dense solidified structure, which is resistant, explosion-proof and pollution-free. The glass fiber and other insulating materials of winding coil have self-extinguishing characteristics, which will not cause the electric arc of short circuit, and the resin will not produce poisonous and harmful gas in high heat. High mechanical strength: packing resin to make casting body expansion coefficient difference is small, small curing shrinkage rate, small internal stress, curing of high hardness, the internal and external surfaces of the high and low voltage coil epoxy resin coating layer, placed with the strengthening of prefabricated molding material, especially as dense as the reinforced concrete structure, and mechanical strength is greater than the pure epoxy resin, can withstand the sudden and short-circuit force without damage.
SZB (DZB) series three- phase dry-type auto-transformers are single-coil type transformer. Its primary and secondary sides share a winding, and the transformation ratios are of fixed and adjustable types, voltage buckling and boosting can be realized. Compared to isolation transformer of the same capacity, auto-transformer has advantages of material-saving, simple structure, small size, light weight and high efficiency. It is particularly economical when the transformation ratio aligns to the occasion. However, due to the sharing of winding between the primary and secondary sides, the initial stage has electrical contact, which shall be considered in some occasions., the main role of dry-type, auto-transformer is to change the voltage class.
Theory In electrical and electronic engineering, a clamp on ct is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe. Clamp on cts are typically used to read the magnitude of alternating current (AC) and, with additional instrumentation, the phase, waveform and harmonics can also be measured. Some clamp on cts can measure currents of 100 A and more. Applications The round jaw design on the P20 AC clamp on ct along with the high content Permalloy core makes them well suited for power quality analyzer applications where high accuracy and low phase shift along with wide frequency are important. Measurement range is 1mA to 120A. It can measure the min current only 1mA, linear good for instruments. The P20 clamp on ct is a general purpose 100A AC current clamp designed for use with DMMs, loggers and other instruments that have a current input. It ha s a 1000:1 ratio and output of 1mA per amp or 1mV per amp measured in the jaw. The P20 has an integral 2.5m lead terminated. The rounded jaw design on this clamp on ct makes it well-suited for power applications where high accuracy 0.1% and low phase shift and wide frequency response are important.
