Voltage transformer is a voltage conversion device. It is converted to low-voltage high-voltage, high pressure in order to reflect changes in the value of the low-pressure value. Therefore automatic terminal machines, can be measured by the voltage transformer voltage directly with ordinary electrical instrumentation. As a result of voltage transformer, a variety of measuring instruments and protective devices are not directly connected to the high voltage in order to ensure the safety and protection work of measuring instruments, but also solve the high-voltage insulation measurement difficulties, and other manufacturing processes. Furthermore terminals models, due to the secondary side voltage transformers are 10 Volt makes measuring instruments and relay coil voltage to standardize manufacturing. Structure and working principle of the common transformer voltage transformer same, which is also the core, a primary winding and secondary winding, terminals and insulation supports other components. Voltage transformer primary winding is connected to the system line voltage or phase voltage insulation should vary with the actual system voltage level may be. The primary winding has more turns, the secondary winding turns rarely supply voltage meter or relay coil. Voltage transformer secondary winding short circuit is not allowed. Secondary winding 10 volts, should be connected to be able to withstand 10 volt circuit, the current through it, and by the size of the secondary circuit impedance to decide. The secondary is shorted, the impedance is small, the current flowing through the secondary circuit is increased, resulting in secondary fuse blown affect meter indication and protection malfunction caused by terminal type, voltage transformer damage. Voltage transformer secondary circuit must be grounded to prevent a secondary high breakdown voltage insulation damage to the secondary side of the string to cause danger to persons and equipment. Fuse terminals: For some special cases in circuit protection, it is the value of an instrument or device immeasurable, due to the instability caused by the loss of current and voltage is very unwise, so in this case you need to have a can protect the device circuit. When the current is too large will automatically disconnect the circuit, which fuse terminal design out. Typically market commonly used specifications for UK5-HESI, UK10-DREHSI and ASK1EN so on. Double terminals: Terminal space designed for the needs, requirements in a small space by more than two cables, which designed the double terminals, common specifications UKK5, UKK3, MBKKB2.5 so on. Products always follow the market, adapt to the market.
