Automatic temperature measurement and early warning device for power equipment in substation

Abstract

The invention discloses an automatic temperature measurement and early warning device for power equipment in a substation, which comprises a temperature acquisition module, a platform server, a mobile terminal and an early warning robot, wherein the early warning robot comprises a wheeled robot body, a main controller, a navigation system, a video navigation probe, a fire extinguishing device and a power device; the fire extinguishing device comprises a powder fire extinguisher; the top end of the powder fire extinguisher is provided with a cover plate and a motor; the cover plate is provided with an electromagnetic valve; one end, far away from the motor, of a transmission shaft is provided with a supporting frame; a fire extinguishing nozzle is arranged on the supporting frame; the powder fire extinguisher is communicated with the fire extinguishing nozzle via a pipeline connected with the electromagnetic valve; and the supporting frame is also provided with an adjustment device for adjusting the height of the fire extinguishing nozzle. A turntable is also included, and the turntable is provided with an opening matched with the pipeline. The device of the invention has the beneficial effects that the accurate position of the temperature sensor can be quickly judged, and the fire safety conditions of the power equipment in the substation can be effectively improved.

Description

Technical field [0001] The invention mainly relates to the field of temperature measurement and early warning of power equipment, in particular to an automatic temperature measurement and early warning device for power equipment of a substation. Background technique [0002] At present, China’s economy continues to develop rapidly, and the power grid is also moving toward the ranks of smart grids, that is, UHV is the main network, and different levels of power grids develop coordinately. Substations are an important component of the power grid. There are a large number of high voltage and high current production in substations. Equipment is prone to fires due to equipment failures, line defects and other problems. Therefore, research on substation equipment detection and fault diagnosis technology is of great value. It can not only reduce the incidence of accidents, but also contribute to the safe operation and reliability of the power grid. For unattended substations, most of th...

Problems solved by technology

[0004] (1) The hand-held infrared detector is only used during the inspection of the substation by the staff, and it does not have simultaneity, continuity and real-time performance. Therefore, it is impossible to perform online monitoring and alarm on various equipment in the station, and it is impossible to realize automatic fault detection. Detection, far from the goal of intelligence

[0005] (2) When diagnosing and identifying equipment faults, the temperature difference of electrical equipment will also be caused by the difference in transmission power and environment. It is not an effective method to diagnose completely based on the difference in temperature. The operation data of the equipment, further research on the fault diagnosis expert system, the existing various manual monitoring systems have phenomena such as untimely alarms, false alarms and missed alarms to varying degrees, so that the safety and practicability of the system cannot be obtained. Assure

[0006] (3) With the rapid development of smart grid, the monitoring system will become larger and larger. If all manual monitoring is used, the labor cost will be very expensive
