Abstract

The invention relates to an electric reactor turn-insulating detection device based on pulse oscillation principle. Two output ends of a transformer are connected with a high voltage silicon rectifier stack, a protective resistor and a resistance voltage divider high / low voltage arm resistor which are connected sequentially and serially; controllable discharge spark gaps and two ends of a damping oscillating circuit are all connected with two ends of the resistance voltage divider high / low voltage arm resistor in parallel; the damping oscillation circuit consists of a damping resistor, a main capacitor and an electric reactor test object; a controller unit is adopted to control the discharge spark gaps to discharge electricity and the transformer to output voltage according to voltage at two ends of the resistance voltage divider high / low voltage arm resistor; pulse oscillation is formed on a pulse oscillation test product in the spark gap discharge process, pulse oscillation signals formed on the electric reactor are transmitted to an oscilloscope through capacitive voltage dividers which are serially connected at two ends of the electric reactor test product, and thus diagnosis on the turn-insulating of the electric reactor is achieved. The electric reactor turn-insulating detection device aims to solve the passive situation that the turn-insulating of the electric reactor cannot be monitored for a long time at present, and has benefits of improving the product quality of an electric reactor manufacturing factory and ensuring the safe operation of a whole power grid.

Description

technical field

[0001] The invention relates to an insulation detection device, in particular to a reactor turn-to-turn insulation detection device based on the principle of pulse oscillation. Background technique

[0002] Dry-type air-core reactors are generally composed of multiple coaxial winding packages, all packages are electrically connected in parallel, there are several coils connected in parallel in each package, and each layer of coils has several small-section metal wires (Usually aluminum wires) are wound together, each wire is wrapped with polyester film or glass wire for turn insulation, and each package is wrapped with long glass fiber impregnated with epoxy resin. After the reactor is wound, After heating and curing, the entire winding envelope forms a solid whole.

[0003] Compared with the traditional oil-immersed iron-core reactor, the dry-type air-core reactor has the advantages of simple structure, light weight, small volume, good linearity, low loss, ...
