Изобретение относитс к электротехнике и может быть использовано дл снижени магнитных полей рассеивани токопроводов многофидерных распределительных щитов посто нного тока.The invention relates to electrical engineering and can be used to reduce the magnetic fields of dispersion of the conductors of multi-feeder DC switchboards.
Известно устройство дл стабилизации напр женности магнитного пол , предназначенное дл подавлени помехонесущего пол , которое содержит первичный преобразователь , расположенный вблизи источника помехонесущего магнитного пол , усилитель и две катущки. Одна катущка предназначена дл создани посто нного магнитного пол , а друга - дл компенсации внещней магнитной помехи 1. В устройстве стабилизации посто нных магнитных полей применены фотоэлектрические стабилизаторы с оптико-механическим преобразователем . В этих устройствах в качестве первичного преобразовател -измерител посто нного пол могут быть также использованы магнитно-модул ционные датчики, датчик Холла с измерител ми. Первичный преобразователь через усилитель управл ет силой тока в катущках. В такой системе стабилизации магнитное поле компенсационной катущки направлено встречно помехонесущему полю.A device for stabilizing the magnetic field strength is known, which is designed to suppress the disturbing field, which contains a primary transducer located near the source of the disturbing magnetic field, an amplifier, and two rolls. One coil is designed to create a constant magnetic field, and the other is to compensate for external magnetic interference 1. In the stabilization device of a constant magnetic field, photoelectric stabilizers with an optical-mechanical converter are used. In these devices, magnetic modulation sensors and a Hall sensor with gauges can also be used as a primary converter for measuring the constant field. The primary transducer controls the current in the coils through an amplifier. In such a stabilization system, the magnetic field of the compensation coil is directed oppositely to the disturbing field.
При применении такого устройства дл компенсации полей рассеивани токопроводов распределительных щитов выходна мощность усилител определ етс величиной исходного пол источника. При больщих значени х исходного пол это приводит к возрастанию веса и габаритов усилител . When using such a device to compensate for the dispersion fields of the distribution box conductors, the output power of the amplifier is determined by the magnitude of the source source field. With large values of the initial field, this leads to an increase in the weight and dimensions of the amplifier.
