to prevent electric shock: the power transformer power supply is generally through the overhead line, and the overhead line is easy to suffer lightning strikes, the transformer will burn due to breakdown insulation.

Shenzhen machinery Exhibition introduction ITES Shenzhen International Industrial Manufacturing Technology Exhibition (the 21st SIMM Shenzhen Machinery Exhibition) is co-sponsored by Shenzhen Huanyue Conference and Exhibition Co., Ltd. and Shenzhen Xiexuan Conference and Exhibition Co., LTD., is a professional exhibition in the field of manufacturing equipment in South China with a very large scale and involving a wide range of categories.

The control transformer can change the voltage, impedance, and even current to meet different requirements. Purchase and use of transformers need to pay attention to the following matters:before the purchase of the control transformer, it is necessary to estimate the total capacity of the electrical appliance, and to leave a margin, so as to avoid the transformer being burned out when it is started instantaneously.

GME Guangdong Machine Tool Exhibition will be held from August 14 to August 17, 2020 in Foshan Tanzhou International Convention and Exhibition Center, located in the core area of the Pearl River Delta - the center of Guangdong, Hong Kong and Macao economic circle. The Guangdong-Hong Kong-Macao economic circle is one of the world's most influential bases for advanced manufacturing and modern service industries.

According to the different output properties of the voltage regulator, the voltage regulator is generally divided into AC voltage regulator (AC voltage regulator power supply) and DC voltage regulator (DC voltage regulator power supply) two categories. The following focuses on DC regulated power supply, referred to as regulated power supply. According to the working state of the regulating tube, the regulated power supply is often divided into two categories: linear regulated power supply and switching regulated power supply. In addition, there is a small power supply that uses a voltage regulator.

the regulator basic principles:Adjustable regulator belongs autotransformers structure, by means of the regulator hand wheel spindle brushes and the brush holder role. On the toroidal uniformly coiled, brushes under spring pressure in close agreement with the polished surface of the coil, the rotation shaft driven brush holder, so that the carbon brushes slide along the coil surface, change the carbon brush contact position that change primary and secondary winding turns ratio of the output voltage to obtain a smooth stepless adjustment within the adjustment range, so as to achieve the purpose of the regulator.

To facilitate the installation of the exchange regulator, small series here today explain installation considerations regarding exchange regulator.We master the correct method of installation exchange regulator also must pay attention to the following six:

We often find SBW regulator failure is largely due to improper maintenance of our cause, and even the majority of users SBW regulator never been serviced. Obviously, this is wrong. SBW regulator is the same with other devices, like we usually require conservation work. Here Xiaobian summed up the points we can inspire hope. SBW regulator uses the process to work regular visits to the state regulator

Precision voltage regulator can be divided into AC and DC voltage regulator. DC is divided into linear and non-linear voltage regulated power supply two categories. Linear power in a stable manner by points, regulator parameters and feedback adjustment regulator. Parameter regulator circuit is simple, mainly using nonlinear components to achieve regulation. For example, a resistor and a Zener diode voltage regulator constitutes parameters. Feedback adjustment regulator having a negative feedback loop, closed loop automatic adjustment system, it has the advantage of mature technology, excellent performance, stability, design and manufacturing simple. Eight high-precision regulator maintenance tips:

Regulator circuit is an important part of the electrical system components, it provides DC bias for the electronic system, to provide a suitable quiescent point for the electronic systems of active devices. Performance DC power directly affects the performance of the entire electronic system. Use the regulator should be noted that the six areas:

If the sound mixed with single-phase transformer are water boiling sound, but also issued a boil bubbles Yat think out loud, which is likely to have more severe winding fault, causing severe fever nearby parts make OIL AND GAS. In fact, as long as the tap-poor contact between local point have serious overheating or single-phase transformer turn short circuit, will this sound. In this case

Regulators have constant voltage control circuit, and a servo motor and other components. Position changed when the input voltage or load changes, sampling control circuit, comparison, amplification, and then drive the servo motor, so that the carbon brush regulator, by automatically adjusting the turns ratio, so as to maintain a stable output voltage.
