       摘要：配電系統(tǒng)是由多種配電設備和配電設施所組成的變換電壓和直接向終端用戶分配電能的一個電力網(wǎng)絡系統(tǒng)。由于配電系統(tǒng)作為電力系統(tǒng)的一個環(huán)節(jié)直接面向終端用戶，它的完善與否直接關系著廣大用戶的用電可靠性和用電質(zhì)量，因而在電力系統(tǒng)中具有重要的地位。因此，為避免因溫度高，導致設備老化，設備燒壞，供電中斷，一次設備起火爆炸等嚴重事故，對各電氣節(jié)點進行長期的溫度監(jiān)測能避免因嚴重故障，造成用戶的人身傷害及經(jīng)濟損失。

　　Abstract: The power distribution system is a power network system that is composed of a variety of power distribution equipment and power distribution facilities to transform voltage and directly distribute electrical energy to end users. As a part of the power system, the power distribution system directly faces end users, and its perfection directly affects the reliability and quality of power consumption of the majority of users, so it has an important position in the power system. Therefore, in order to avoid serious accidents such as equipment aging, equipment burnout, power supply interruption, fire and explosion of equipment due to high temperature, long-term temperature monitoring of each electrical node can avoid serious failures that may cause personal injury and economic loss to users.
