The PT distribution cabinet is the distribution cabinet of the Potential Transformer. The following is a detailed introduction: ### I. Basic Functions 1. **Voltage Transformation** - It is mainly used to transform the high voltage on the primary side into a low voltage that can be used by secondary equipment such as instruments and relays in proportion. Generally, the secondary side voltage of a common potential transformer is 100V (in China's power system). For example, in a 10kV power system, the high voltage of 10kV is converted into a low voltage of 100V through the PT, enabling the measuring instruments to measure voltage parameters safely and accurately. 2. **Isolation Function** - The PT distribution cabinet can achieve electrical isolation between the primary circuit and the secondary circuit. This is very important for ensuring the safety of secondary equipment and personnel. Because the primary side is usually a high-voltage system, without this isolation, the high voltage may enter the secondary side, damage the secondary equipment and pose an electric shock hazard to the operators. ### II. Internal Structure 1. **Potential Transformer** - This is the core component of the PT distribution cabinet. Its working principle is similar to that of a transformer and it consists of primary and secondary coils. The primary coil has a relatively large number of turns and is connected to the high-voltage side; the secondary coil has a relatively small number of turns and is connected to the secondary equipment. According to the law of electromagnetic induction, when there is a voltage change on the primary side, a corresponding proportional voltage will be induced on the secondary side. There are different types of potential transformers, such as electromagnetic potential transformers and capacitive potential transformers. - The electromagnetic potential transformer has a relatively simple structure and is composed of an iron core, primary and secondary windings, etc. The iron core is made of laminated silicon steel sheets and is used to concentrate the magnetic flux. The number of turns of the primary winding is determined according to the voltage level of the primary side, and the number of turns of the secondary winding is designed according to the transformation ratio requirements. - In addition to the voltage transformation function, the capacitive potential transformer can also utilize the principle of capacitance voltage division. It mainly consists of a capacitive voltage divider and an electromagnetic unit. The capacitive voltage divider divides the primary high voltage, and the electromagnetic unit further transforms and processes the divided voltage and outputs an appropriate secondary voltage. 2. **Fuse** - In the PT distribution cabinet, the fuse is an important protective element. The primary side fuse is mainly used to protect the potential transformer itself. When the transformer has a short circuit or other faults, the fuse will blow to cut off the fault current and prevent the fault from expanding. The secondary side fuse is used to protect the secondary equipment and prevent the secondary side circuit from being damaged due to short circuits and other faults. 3. **Secondary Circuit and Terminal Block** - The secondary circuit includes wires connecting the secondary winding of the potential transformer and various secondary equipment (such as voltmeters, wattmeters, relay protection devices, etc.). The terminal block is used to conveniently connect and disconnect the secondary equipment and can clearly identify the functions and connection positions of each circuit. ### III. Application Scenarios 1. **Substation** - In#trending #electric #electricalengineer #kimtuotdaydien #foryou #Vlog #tiktok #fry #chargeman #sparky #fyp #electrician #electricianlife #fypシ #electricaltips #Angola #www.skfbearing.com #electriciansoftiktok #dayinthelife #dayinmylife #Transformer #switchgears
