Description

УСТРОЙСТВО ДЛЯ ПОЛЯРИЗАЦИИ ПЬЕЗОКЕРАМИКИDEVICE FOR POLARIZING PIEZOCERAMICS

1one

Изобретение относитс  к области радиоэлектроники и может быть исиользовано дл  осуществлени  пол ризации пьезокерамических изделий электрическим полем.The invention relates to the field of radio electronics and may be used to polarize piezoceramic products with an electric field.

Известные устройства дл  пол ризации пьезокерамики , содержащие выпр митель, на выходе которого включепы пол ризуемые образцы , в процессе пол ризации мен ют режим работы, вследствие чего происходит резкий разогрев пол ризуемых образцов и может произойти их пробой.The known devices for the polarization of piezoelectric ceramics, containing a rectifier, at the output of which the polarized samples are turned on, during the polarization process change the mode of operation, as a result of which the polarized samples are heated up and can break down.

С целью обеспечени  устойчивого режима пол ризации в предлагаемом устройстве на входе выпр мител  включен пьезотрансформатор с генератором звуковой частоты.In order to provide a stable polarization mode in the proposed device, a piezotransformer with an audible frequency generator is included at the input of the rectifier.

На чертеже приведена функциональна  схема предлагаемого устройства дл  пол ризации пьезокерамики.The drawing shows a functional diagram of the proposed device for the polarization of piezoelectric ceramics.

22

Устройство содержит генератор 1 звуковой частоты, пьезотрансформатор 2, выпр митель 3 и пол ризуемые образцы 4.The device comprises an audio frequency generator 1, a piezotransformer 2, a rectifier 3 and polarizable samples 4.

Напр жение с генератора / звуковой частоты подаетс  на вход пьезотрапсформатора 2, усиливаетс  и через выпр митель 3 подаетс  па пол ризуемые образцы 4 пьезокерамических изделий.The voltage from the generator / audio frequency is fed to the input of the piezoelectric transformer 2, is amplified, and through the rectifier 3, the polarized samples 4 of the piezoceramic articles are fed.

Предмет изобретени Subject invention

Устройство дл  пол ризации ньезокерамики, содержащее выпр митель, на выходе которого включены пол ризуемые образцы, отличающеес  тем, что, с целью обеспечени  устойчивого режима пол ризации, на входе выпр мител  включен пьезотрансформатор с генератором звуковой частоты.A device for polarizing low ceramics containing a rectifier, the output of which includes polarizable samples, characterized in that, in order to ensure a stable polarization mode, a piezotransformer with an audio frequency generator is switched on at the input of the rectifier.
