The working principle of electronic transformer

polemounted transformers is no regulated switching power supply, it is actually a kind of inverter. First, the AC rectifier into DC, and then use the electronic components to form a high-frequency oscillator to DC into high-frequency AC, through the switching kiosk transformers output voltage required for the secondary rectifier for electrical use. Switching power supply with a small size, light weight, low price, it is widely used in a variety of electrical appliances. According to the high-frequency switch drive different ways, can be divided into self-excited oscillation and he excited type.

Electronic transformer works - application

single phase pole mounted transformers in the traditional lighting applications are common, such as fluorescent lamps, table lamps, energy saving lamps, advertising lights, etc. can almost all use electronic transformers, and the use of electronic transformers, you can save the starter. In LED lighting, the new products are mostly electric transformer substation. Mainly electronic transformer in the transformer function, high efficiency, cost at the end, saving iron copper material, small structure, light weight. Insufficient resistance to pressure and high-current impact resistance than the iron transformer poor.

There may be capacitance between the high-voltage and low-voltage windings of the 11kv single phase transformer, between the low-voltage winding and the core, between the core and the tank wall. Charged transformer winding through the coupling of the capacitor, it will cause the iron core to the (tank wall) to produce a certain floating potential, due to the various metal parts within the dry cast resin transformer and the fuel tank wall ranging from the same, the suspension potential is different, To a certain potential difference, it will on the (tank wall) discharge, a direct result of core insulation damage. Therefore, the transformer core must be reliably grounded.

The main difference between conventional pole transformer no-load operation and load operation is mainly reflected in the secondary coil.
Transformer The principle of using electromagnetic induction to change the AC voltage of the device, the main component is the primary coil, secondary coil and core (core). In electrical equipment and wireless circuits commonly used for lifting voltage, matching impedance, safety isolation. 13.8kv single phase transformer no-load operation, only the consumption of no-load loss, that is, iron loss and stray, it is 6% of the total capacity, load operation is no load loss + load loss, that is, copper loss, is the total consumption of the transformer.

50 kva pole mount transformers are made using a core

50 kva pole mount transformers are made using a core made from laminations of sheet steel stacked and either glued together with resin or banded together with steel straps. Where large numbers of transformers are made to standard designs, a wound C-shaped core is economic to manufacture. A steel strip is wrapped around a former, pressed into shape and then cut into two C-shaped halves, which are re-assembled on the copper windings.
Formerly, distribution transformer

for indoor use would be filled with a polychlorinated biphenyl (PCB) liquid. Because these liquids persist in the environment and have adverse effects on animals, they have been banned. Other fire-resistant liquids such as silicones are used where a liquid-filled transformer must be used indoors. Certain vegetable oils have been applied as transformer oil; these have the advantage of a high fire point and are completely biodegradable in the environment.

50kVA, 6 Way Mobile Power Transformer

The 50kva power transformer, 6 way mobile power source transformer, is housed in a robust, mild steel box section frame which has wheels fixed ot the base for ease of movement. This transformer has the capacity to run eighteen, 60 volt, 2.7kw ceramic heaters from its secondary output supply. The front control panel consists of P159CF mini controllers and energy single phase step voltage regulators

which can be used ot perform pre and post weld heat treatment. Neon indicator lights are fitted to enable the user to see clearly when a channel is in use. It also features an auto/manual switch to allow the use of an external automatic temperature programmer, twelve female panel mounted twistlocks are fitted to enable the triple cable sets to be connected and there are six thermocouple sockets on the front of the unit and additional sockets are also fitted to the rear of the unit. The rear of the unit also features 3 x 110V auxiliary sockets, a ventilation fan, main circuit breaker and both multi plug and single channel connections for use with external programmers.
