1、系统简介

1, the introduction of system 

高压电网中众多电气设备本身和设备之间的连接点是电力输送最薄弱环节。随着负荷的增大，这些薄弱环节会出现发热现象，并形成恶性循环：温升、膨胀、收缩、氧化，电阻增大、再度升温直至酿成事故。

The connection between the many electrical equipment and the equipment in the high voltage grid is the weakest link in the transmission of electricity. With the increase of load, the weak link will appear fever phenomenon, and form a vicious circle: temperature, expansion, contraction, oxidation, resistance increases, heating up again until the accident. 

根据运行经验，需要监测的高压电器设备易发热部位如下：

According to the running experience, the high voltage electrical equipment that needs to be monitored is as follows: 

（1）高压（220KV、110KV、35KV、10KV）变压器的输入输出连接点和箱体表面；

(1) the input and output join points and the surface of the box for high pressure (220KV, 110KV, 35KV, 10KV) transformer. 

（2）高压母线、母排接头，穿墙套管，铜铝过渡处；

(2) high voltage bus, female line joint, wall sleeve, copper and aluminium transition; 

（3）高压开关柜的动静触头及柜内断路器等各种接点；

(3) all kinds of contact points, such as the movement of the switch cabinet and the breaker in the cabinet. 

（4）地下电缆及电缆夹层通道；

(4) underground cable and cable channels; 

（5）发电机定子、干式箱式变电站等的发热部位；

(5) the heating parts of generator stator and dry box substation; 

（6）刀闸、开关等连接部位

(6) cutting, switch, etc 

通过利用在发热部位触点位置安装无线传感器，实时采集各触点的温度，通过无线方式上传到监控中心后，变电运行人员可快速了解设备是否有发热情况,从而可为设备安全的运行提供技术保障。

By using location installed wireless sensor in the heating area, real time collection and the temperature of each contact, wirelessly uploaded to the monitoring center, substation operation staff can quickly understand the equipment if there is fever, which can provide technical support for the operation of the equipment safety. 

2、系统特点

2, the system characteristics 

1) 多种温度监测方式

1) various temperature monitoring methods 

系统设定自动采集任务，定时按照既定的采样频率进行温度信息的采集。温度数据保存在数据库中，用户可以设定时间区间、指定监控对象进行历史温度信息的查询。

The system set up automatic collection task, timing the gathering of temperature information according to the fixed sampling frequency. The temperature data is stored in the database, and the user can set the time interval and specify the query that monitors the historical temperature information. 

2) 完备的告警机制

2) complete alarm mechanism 

当设备的温度的绝对值或温度的变化率超过上限，系统为运行管理人员提供声音、光电等多种方式的告警信息。及时或预知性的发现和排除故障，从而最大限度的保障电力设备的安全稳定运行。

When the temperature of the temperature of the device exceeds the limit of the temperature, the system provides the alarm information of the sound, photoelectric and other ways for the running manager. Timely or precognitive discovery and troubleshooting, thus ensuring the safety and stability of power equipment. 

3) 完善的系统参数设置

3) perfect system parameter Settings 

建立各级监测点的温度监测及管理网络，管理温度监测相关的设备、传感器、读入器等各类设备档案。

To establish the temperature monitoring and management network of monitoring stations at all levels, manage temperature monitoring equipment, sensors, reader, etc. 

4) 丰富的数据展现

4) rich data presentation 

对于历史温度信息，系统提供列表、曲线等多种展现方式，方便用户进行查看。

For historical temperature information, the system provides a variety of display modes such as lists, curves, etc., which is convenient for users to view.
