Passive temperature test system for key point of primary equipment in substation

Abstract

The invention discloses a passive temperature test system for the key point of primary equipment in a substation. The system comprises a UHF-RFID electronic tag, a reader and a background management and analysis system. The passive electronic tag is attached to an equipment temperature detection point. An operator carries the hand-held reader to conveniently read the actual temperature of the equipment temperature detection point. The hand-held reader transmits the temperature information to a background server in the serial communication manner. The temperature information analysis of the electronic tag is realized based on the background system software in combination with the network communication technology, the database management technology and the like. Meanwhile, the current state information of the equipment is automatically provided.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a passive temperature testing system for key points of substation primary equipment. Background technique [0002] Timely equipment inspection of the power system directly affects the normal operation of the power transmission and transformation system, is related to the normal operation of power distribution and power consumption systems, and even affects the entire power system. All major operating power supply companies have multiple substations, and each substation has hundreds of equipment monitoring points, and the amount of manual inspection and recorded data is huge. The inspection of the primary equipment monitoring point of the substation is mainly to collect the temperature data of the key points of the equipment, and to realize the early warning by analyzing and collecting the status information such as the temperature of the substation equipment with identification infor...

Problems solved by technology

[0003] The existing temperature measurement methods mainly adopt two methods, one is the method of placing temperature test wax sheets on the key parts that are prone to heat, which is backward and labor-intensive; the other is the use of infrared temperature measurement technology for temperature detection. It is easy to miss the details, and the equipment is expensive, and the test accuracy is mainly affected by the operator; due to time constraints, the measurement during the day is easily affected by the sunlight, and sometimes it must be measured at night
