220kV 145kV 132kV SF6 Inductive Voltage Transformers

الوصف

Product Name:SF6 Inductive Voltage Transformers 
1.Technucak Parameters:

The system earthing mode is Non-effectively earthed neutral system 
2.Frame Instruction:
2.1 It is an inductive voltage transformer which the insulation material is SF6 gas.2.2 The bushing of the voltage transformer is made by silicon rubber or porcelain. There are some aluminum electrodes inside the voltage transformer, to improve the electric field distribution inside the voltage transformer.
2.3 There is a pressure relief device at the top of the voltage transformer, when the pressure is more than 0.8MPa if the voltage transformer is discharge inside, the relief device will be broken to release the pressure and sendan alarm information.
2.4 There is a SF6 density monitor fix at the base, it can indicate the SF6 pressure which inside the voltage transformer (its indicated value is the SF6 pressure at *0℃), and it will provide an information when the SF6 pressure is drop down to the minimum service pressure of the voltage transformer, to remind the user replenish the SF6 gas to the rated pressure.
2.5 The secondary terminals block is casted by epoxy resin, the frame of the secondary terminals box is a seal structure, and it suits for outdoor.
