在高电压交、直流输电过程中,某些场合需要将弱电信号测量装置安装于高电压环境下,通过测量装置获得的信号一般是电信号,而高电压侧的电信号是不可能不经过处理就直接传输至地面的低电压侧。将高电压侧电信号传输至地面可使用两种方法,一种是无线通信,适用于信号的传输速率不太高的情况下;一种是光纤通信,可高速传输信号。在光纤通信中,高电压侧的测量信号转变为光信号后要通过光纤绝缘子通到低电压侧,而在此过程中间需要光缆转接盒,如何设计光缆转接盒的结构能避免在高电压环境下引起电晕放电是保证光缆转接盒可用性的关键。In the process of high-voltage AC and DC transmission, in some occasions, it is necessary to install weak current signal measurement devices in high-voltage environments. The signals obtained through the measurement devices are generally electrical signals, and it is impossible for the electrical signals on the high-voltage side to be processed. It is directly transmitted to the low voltage side of the ground. There are two ways to transmit the electrical signal on the high-voltage side to the ground. One is wireless communication, which is suitable for situations where the signal transmission rate is not too high; the other is optical fiber communication, which can transmit signals at high speed. In optical fiber communication, after the measurement signal on the high-voltage side is converted into an optical signal, it must be passed to the low-voltage side through an optical fiber insulator. In the middle of this process, an optical cable transition box is required. How to design the structure of the optical cable transition box to avoid the high-voltage The corona discharge caused by the environment is the key to ensure the availability of the optical cable junction box.
