Substation Monitoring Device and System Based on Infrared Thermal Imager

Abstract

The invention provides a transformer substation monitoring device based on a thermal infrared imager and a system thereof, and relates to the technical field of electric power. The device comprises a thermal infrared imager, a light emitter, a spherical reflector, a light receiver, a controller and a supporting piece; the spherical reflector is installed on a power device to be tested; the light receiver is used for generating and sending the collected start signal to a controller when light reflected by the spherical reflector is received; the supporting piece comprises a rotational base, a lifting pillar and a fixing base which are connected in order; the ground collecting point is corresponding to the position of the power equipment to be tested; the installing directions of the thermal infrared imager, the light emitter and the light receiver are the same; when the collected start signal is received, the controller controls the supporting piece to stop rotating and lifting and also controls the thermal infrared imager to collect the infrared thermography; the controller further comprises a wireless communication module which is used for sending the infrared thermography to the remote terminal and receiving the control command. The invention can realize the online temperature monitoring and high precision measurement.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a substation monitoring device and system based on an infrared thermal imager. Background technique [0002] Various power transmission and transformation equipment in substations, due to long-term operation and the influence of environmental factors, cause various failures, which affect the operation of the entire power supply system and cause economic losses. With the rapid development of the modern power industry, the power supply system has higher and higher requirements for the distribution quality of electric energy. Any problem in the production, transmission and distribution of electric energy in the power system will affect the normal operation of the entire system. As a key link in the operation of the power system, the substation is an important task of power management to ensure its safe operation and ensure that the power equipment is in a stable and good ope...

Problems solved by technology

At present, the fault detection of power equipment in the power system usually uses a handheld thermal imaging camera for detection. The handheld thermal imaging camera has problems such as manual operation, continuous monitoring, and inability to actively alarm.

[0004] Aiming at the problems of low efficiency and inability to continuously monitor and alarm the detection methods of the above-mentioned handheld thermal imaging cameras, no effective solutions have been proposed so far.
