Problems solved by technology

At present, due to vibration, corrosion, thermal expansion and contraction, the contacts of cable joints, wire clamps, knife switches, switches and other contacts in the distribution line will loosen to form contact resistance. The temperature rise, long-term high temperature will cause irreversible damage to the equipment and even turn into an accident

Abstract

The invention discloses a power distribution network on-line temperature measurement system and method. The system comprises a temperature measuring unit, a data collecting terminal and a system main station; the temperature measuring unit is used for acquiring the temperature data of a monitored line and transmitting the temperature data to the data collection terminal through a micro power wireless communication mode; the data collecting terminal is used for receiving the temperature data sent by the temperature measuring unit through a micro power wireless communication mode and transmitting the temperature data to the system master station through a wireless network; and the system master station is used for receiving the temperature data send by the data collection terminal and performing temperature monitoring on the monitored line according to the temperature data. According to the power distribution network on-line temperature measurement system and method of the invention, the temperature measuring unit is utilized to perform real-time monitoring on the key nodes and equipment of a power distribution network in real time, so that the running status of the power distribution network can be mastered in real time; when an abnormal event occurs, information can be initiatively reported in order to inform operation and maintenance personnel in time, so that effective prevention and timely processing of a fault can be realized, and therefore, the efficiency of operation, maintenance and emergency repair can be effectively improved, and power outage time can be reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution facility monitoring, and more specifically relates to an online temperature measurement system and method for a power distribution network. Background technique [0002] The distribution circuit refers to the line that sends power from the step-down substation to the distribution transformer or sends the power from the distribution substation to the power unit. At present, the contacts such as cable joints, wire clips, knife switches, and switches in distribution lines will loosen due to vibration, corrosion, thermal expansion and contraction, etc., thereby forming contact resistance. Prolonged high temperature will cause irreversible damage to the equipment and even turn into an accident. [0003] Therefore, how to conduct real-time online monitoring of the temperature of key nodes of distribution network equipment to avoid electrical fire accidents is a problem to be solved by those ...
