Abstract

The invention discloses a magnetic valve type controllable reactor wireless temperature state monitoring system and method. In the monitoring system of the present invention, the adsorption wireless temperature sensor is adsorbed on the high-temperature heating point on the magnetic valve type controllable reactor box; The humidity sensor is placed in the excitation cabinet of the magnetic valve type controllable reactor; each sensor collects on-site data, and uploads the data to the wireless data receiving terminal through RF radio frequency wireless communication; the wireless data receiving terminal packs the received data, And transmit the data to the industrial computer through RF radio frequency wireless communication; the industrial computer is connected with the magnetic valve type controllable reactor controller through the field bus, and is used to issue control instructions to the magnetic valve type controllable reactor controller. The invention is easy to install, convenient to add temperature monitoring to the existing magnetic valve type controllable reactor, and has low installation and later maintenance costs.

Description

technical field [0001] The invention relates to the field of temperature state monitoring of a magnetic valve type controllable reactor, in particular to a wireless temperature state monitoring system and method for a magnetic valve type controllable reactor. Background technique [0002] Due to the construction of UHV / EHV, long-distance transmission lines and more and more power electronic equipment connected to the grid, dynamic reactive power compensation has become more and more urgent. The magnetically controlled shunt reactor (MCR) has been widely used in the field of dynamic reactive power compensation due to its advantages of continuously adjustable output reactive power and simple control. [0003] Due to its special structure (reduced cross-sectional area) and the existence of DC magnetic aid, the MCR magnetic valve is in a saturated state for a long time, resulting in a much higher unit volume loss of the iron core magnetic valve section than other parts. In actu...

Problems solved by technology

[0005] 1) To monitor the temperature inside the MCR core through pre-embedded optical fibers, the optical fiber temperature measurement system must be installed at one time during MCR manufacturing and assembly, which is costly and difficult to modify and maintain later;

[0006] 2) The optical fiber temperature sensor may fall off and decompose after soaking in transformer oil for a long time;

[0007] 3) It is necessary to transmit the temperature measured by the optical fiber temperature sensor to the monitoring platform through a wired method, which will make the on-site wiring of the magnetic valve controllable reactor cumbersome, which is not conducive to high-voltage insulation

The temperature rise effect caused by the device loss of these high-power thyristors and diodes, and the high temperature and humidity of the environment may also affect the stability of the device and the entire MCR system, so it also needs to be monitored
