We Research New Products ‘’Balun Transformer’’

We are glad to inform you we research new products ‘’Balun Transformer’’ at. March 2008 

Barron (Balun) also called balance converter, is microwave balanced mixer, multiplier, push-pull amplifier and antenna feed network balance circuit layout of the key components, such as wireless local area network (wlan) is a key technology of rf front-end circuit design, a direct impact on the quality and performance of wireless communication. The difference is the main task of the antenna feeder high efficiency transmission power, at the same time to ensure the symmetry of balance feed. In ultrashort wave frequencies, if USES parallel double wires do its feeder, although can guarantee this kind of balance, but because of its open structure, will produce a strong reflection, in order to prevent the leakage of electromagnetic energy and not easily affected by climate and environment, the influence of such factors as feeder usually adopt shield coaxial cable, but if directly connected to the antenna side, will destroy the symmetry of the antenna itself. This imbalance not only change the antenna input impedance matching, the distortion and the antenna pattern.

Balance transformer is more and more people love 

Balance transformer is transform alternating voltage and alternating current and impedance of the device, when the primary zhongtong have alternating current coil, iron core (or core) to produce ac magnetic flux, induced in the secondary coil voltage (or current). Balance transformer is composed of iron core (or core) and the coil, coil, there are two or more than two windings, which connect power winding is called primary coil, the rest of the winding is called secondary coil. 

Barron transformer common faults: 

(1) balance transformer after shutdown when sending or hours.then, often found that the voltage is not normal, such as two phase in a low or instructions to zero; Some new rotor balance transformer three-phase voltage is very high, make some burning due to high voltage electrical equipment; 

(2) high pressure blown fuse send electricity; 

(3) after a thunderstorm barron transformer to send electricity; 

(4) balance transformer abnormal sound, such as a "make" or "Pi pa" noise; In operation of the "pumping wow pumping wow" cry like frogs, etc.; 

Terminal burn out (5) high pressure and high pressure casing has a serious breakage trace; 

(6) under the condition of normal cooling, barron transformer temperature disorder, and rising; 

(7) oil ranks, color change oil in carbonaceous; 

(8) balance transformer roar, airway in security, to oil storage tank, oil tank, oil spill, oil leakage and radiator pipe deformation, etc. 

Solution: 

(1) in the new substation, high and low voltage fuse installation in time according to the specification. Found in barron in the operation of the transformer, fuse burned or have it stolen, it should be replaced in a timely manner; [1] 

(2) the reasonable allocation of high and low voltage fuse piece: 

(1) the balance of capacity above 100 kva transformer to configure 2.0 ~ 3.0 times the rated current of fuse; 

(2) under 100 kva capacity balance transformer to configure 1.5 ~ 2.0 times the rated current of fuse piece; 

(3) low voltage side is a little bigger fusing pieces should be according to the rated current.
