The invention discloses a magnetic leakage field measuring type dry-type reactor on-line monitoring device and method. The device comprises a Gauss meter, and an upright column installed at the symmetrical center of three dry-type reactors which are triangular-shaped, wherein the top end of the upright column is provided with a sensor of the Gauss meter; the sensor is used for acquiring a magnetic leakage field of the dry-type reactors in real time; the upright column is provided with a Gauss meter head, and the Gauss meter head is connected with a computer of a control chamber through a signal line, and the computer is used for receiving a current signal after conversion through the Gauss meter, making a comparison analysis between the received current signal and a threshold value stored inside, and if the current value of the current signal exceeds the preset threshold value, sending alarm information; and the power supply line of the Gauss meter is connected with the control chamber. Since the Gauss meter is installed at the plumb line of the gravity center of the equilateral triangle composed of the dry-type reactors, and a magnetic leakage field vector sum at any one point on the plumb line equals to a zero vector so that through determining the magnetic leakage field amount, the on-line monitoring on the dry-type reactors can be performed, and accidents can be effectively prevented.
Description
technical field [0001] The invention belongs to the technical field of monitoring equipment for dry-type reactors, and in particular relates to an on-line monitoring device and method for dry-type reactors with leakage magnetic field measurement. Background technique [0002] So far, dry-type air-core reactors or dry-type half-core reactors and other dry-type reactors have suffered severe burnout accidents in many substations and converter stations, including ultra-high voltage, ultra-high voltage substations and ultra-high voltage converter stations. These accidents have seriously affected the safe operation of the power station and caused huge losses. [0003] There are many reasons for dry-type reactors to burn out. For example, dry-type reactor coils generally use cylindrical winding. Each reactor coil is composed of multiple packages. The turn insulation between wires is very thin. Metal debris or other foreign matter can easily penetrate the turn insulation, causing a...
