Wireless temperature measuring device for electric reactor

Abstract

The invention discloses a wireless temperature measuring device for an electric reactor, and relates to the technical field of electric reactor operating temperature detection. As an internal cavity of a dry-type hollow electric reactor is complex, it is especially necessary to monitor temperature field distribution in a packet, a temperature measuring device needs to go deep into the electric reactor, and it is relatively difficult to mount a wireless temperature measuring device. The wireless temperature measuring device for the electric reactor comprises a temperature measuring probe arranged on a probe fixing block, and a wireless temperature measuring transmitter arranged in a transmitter magnetic shielding sealed shell, wherein the transmitter magnetic shielding sealed shell is fixedon an electric reactor transverse part through a transmitter fixing seat, the probe fixing block is pasted and fixed on an inner packaging wall of the electric reactor through a detachable temporaryauxiliary mounting fixed frame, the temperature measuring probe is connected with a temperature measuring transmitter through a temperature measuring wire, the temporary auxiliary mounting fixed framecan conveniently extend the probe fixing block with the temperature measuring probe onto the inner packaging wall of the electric reactor for pasting and fixing. The wireless temperature measuring device is convenient and reliable to mount and fix; and the transmitter magnetic shielding sealed shell can effectively prevent the wireless temperature measuring transmitter from self-heating.

Description

Technical field [0001] The invention relates to the technical field of reactor operating temperature detection, in particular to a reactor wireless temperature measuring device. Background technique [0002] At present, dry-type hollow shunt and series reactors with voltage levels ranging from 10kV to 66kV and 110kV are widely used in the reactive power compensation devices of 110kV, 220kV, 330kV and 500kV substations. The series reactor will consume power on the coil due to the large current during the operation of the power system, causing the coil to heat up and even burn out. In order to improve the voltage quality of the power grid and ensure reliable and stable operation of the reactor for a long time, it is necessary to take corresponding measures to monitor and monitor the temperature and temperature rise of the reactor in real time. [0003] Wireless temperature monitoring technology is an emerging technology in recent years: within a range of several hundred meters, mult...
