Isolation transformer is a special kind of transformer, its input winding and output winding are connected in an electrically isolated way, mainly used for In the case where the polarities are separated, it is used to exert electrical isolation and obtain the function of step-up and step-down at the same time. The main purpose of the isolation transformer is to isolate two related circuits. It is usually used for power lighting, power control, and lightning protection filter separation in the electronics industry, industrial and mining enterprises, machine tools, and mechanical equipment to prevent machine short circuits. Appear. The working principle of the isolation transformer> is very simple. It forms electrical isolation by isolating the primary and secondary winding coils, thereby preventing short circuits and ensuring the safety of the robot to a greater extent. It is widely used in the power industry in European countries to play the role of protection, lightning protection, filtering, and to avoid accidental contact with electrified bodies.
Ordinary transformer is a common power supply component used to change the magnitude of AC voltage, it will be small The voltage input is converted into a large voltage output. It works by mutual coupling of magnetic flux, there is no wire connection between the coils of the primary side and the secondary side so that the current can flow directly, and it can provide an isolation voltage of up to several thousand volts without the risk of insulation breakdown. Common transformers can be used to vary the voltage, while isolation transformers with a turns ratio of 1:1 are also used in safety-related applications. The application of transformers in life is ubiquitous, from electric kettles to home appliances, etc., almost all of them have power transformers. In power networks, transformers are often used for voltage conversion, enabling high-voltage lines to be used by various low-power users. In short, the ordinary transformer is a very important power supply component, which is widely used in various fields.
An isolation transformer> is an electrical device designed to prevent the flow of electrical current between a primary and a secondary. It consists of primary and secondary coils and possibly oil-insulated components. In this type of transformer, there are no conductors between the coils, so current cannot flow directly through them.
Isolation transformers> are basically the same as ordinary transformers. The coil is not connected to the ground, so make the connection between any secondary line and the groundThere is no potential difference between them, which is safer to use. In addition, isolation transformers are the most commonly used equipment for repairing power supplies, and can be widely used in scientific research, medical instruments, computers and power grids.
Isolation transformer> is a transformer used to provide pure power supply voltage. Accidental contact with live parts and ground hazard. Through the principle of electromagnetic induction, it can effectively isolate the power circuit and secondary circuit, prevent power pollution, interference and ensure the safe operation of various electrical equipment. Isolation transformers are widely used and can be used in complex power environments such as subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises, and tunnel power transmission and distribution.
The isolation transformer is a very useful device to prevent the third harmonic and interference signals from disturbing the stable operation of the power grid. It can effectively reduce the distortion of the nonlinear load current, clear the third harmonic signal of the power grid, reduce the interference signal, and generate a new neutral line to solve the problems caused by the unbalanced load current caused by the bad neutral line between the grid and the grid. In order to achieve the purpose of stabilizing and protecting the power grid. At the same time, it can avoid affecting the sampling accuracy and obtain real-time control signals, so as to maximize the efficacy of nonlinear loads.
Isolation transformers> can change the transmitted voltage. Also, it is primarily a reference point between isolating 220V and another voltage. When the 220V is not connected to the ground, no current will flow by holding its neutral wire or touching the ground. And when it is connected to the ground, if you hold the 220V live wire, you will be in danger of getting an electric shock, because the ground constitutes a reference point for a loop. Only an isolation transformer can effectively isolate the reference point between 220V and another wire, thus guaranteeing that even holding any wire is not dangerous.
