无线电通信,由于不受电力系统运行方式的制约,加之投资省、见效快、性能稳定可靠,在电力系统通信中被广泛采用.但是,目前电力系统中使用的电台,通常是在某指定组别内使用的某一特定频道,因而信道是单一的.本文就WT24—Ⅱ特高频(多信道)通信机的特点、原理、安装及维护要求作一简介,以此来推动特高频通信技术在电力系统通信领域的推广和应用.一、主要特点WT24—Ⅱ24路特高频通信机是由特高频接收机、发射机和24路载波电话终端机三部分组成,合装在一个机架内,可提供25个载波电话电路,其中一个话路作为公务联系使用.由于本设备使用频率较高,电波传播比较稳定,不受视距传播的严格限制,能适应较复杂的地形条件.同时,通过适当组合(转接)可以延长通信距离.采用调频制式(FM),信噪比高,抗干扰能力强,通信质量好,操作维护方便.该设备的主要特点是:
Radio communication is widely used in power system communication because it is not restricted by the operation mode of the power system, save energy, save money, be stable and reliable, but the radio stations used in the power system are usually in a designated group Within a specific channel, so the channel is single.This article WT24-Ⅱ UHF (multi-channel) communication machine features, principles, installation and maintenance requirements for a brief introduction, in order to promote high-frequency communication technology In the field of power system communication promotion and application I. Main features WT24-Ⅱ 24-way UHF communication device is composed of UHF receiver, transmitter and 24 carrier phone terminals in three parts, together mounted on a rack , It is possible to provide 25 carrier telephone circuits, one of which is used as a public service contact, and due to the high frequency of use of the equipment, the radio waves are relatively stable and not subject to strict restrictions of line-of-sight propagation and can adapt to more complicated topographical conditions. , Through the appropriate combination (transfer) can extend the communication distance.Using FM, high signal to noise ratio, anti-interference ability, good communication quality, easy operation and maintenance. The main features of the device are:
