Abstract
The invention discloses an optical method-Perot partial discharge sensor installation method at a large-scale power transformer clamp member portion, belonging to the electric device field. The invention solves the problem that the optical method-Perot partial discharge sensor which is used for local discharging for inducing the supersonic wave signal can cause the electric field change inside the large scale power transformer and thus affects the operation of the large scale power transformer. The optical method-Perot partial discharge sensor is fixed inside of the angle of the large scale power transformer clamp member through the epoxy resin, which, basically, does not cause the electric field change inside the large scale power transformer, and guarantees the stable operation of the large scale power transformer. The installation method of the invention is applicable to the installation of the optical method-Perot partial discharge sensor at the clamping portion of the large scale power transformer.
Description
Technical field
The present invention relates to a kind of sensor installation method at power transformer folder place, belong to electrical equipment.
Background technology
The on-line PD monitoring of large-scale power transformer is always up a difficult problem for puzzlement power operation unit, and engineers is attempting adopting diverse ways to solve this difficult problem always. in existing solution, detection office puts the mode bringing out ultrasonic signal and receives much concern, traditional office puts and brings out ultrasonic signal detection equipment based on piezoceramic transducer, metallic elements is contained and by propagation of electrical signals information in the inside of such sensor, this makes it can only be installed on the outer wall of the fuel tank of large-scale power transformer to the office within large-scale power transformer and put bring out ultrasonic signal detect, and such sensor is highly prone to the high-intensity magnetic field of large-scale power transformer generation and the interference of highfield, its office detected is made to put the less stable bringing out ultrasonic signal. the simple in construction of sensor is put in existing optical fiber Fabry-Perot office, volume is little, metallic elements is not contained in inside, entirety belongs to dielectric and carries out information transmission by optical signal, this makes it will not be subject to the interference of the high-intensity magnetic field of large-scale power transformer generation and highfield, the inside detection office of large-scale power transformer can be installed in put and bring out ultrasonic signal, but the internal structure of large-scale power transformer is complicated, electric field is extremely strong, even small dielectric is integrated within also causing electric field change, produce chain reaction and affect the properly functioning of large-scale power transformer.
Summary of the invention
The invention aims to solve to be installed in inside large-scale power transformer, put the optical fiber Fabry-Perot office bringing out ultrasonic signal for the office of detection and put sensor and can cause the electric field change within large-scale power transformer, affect the problem that large-scale power transformer runs, it is proposed that the sensor installation method at large-scale power transformer folder place is put in a kind of optical fiber Fabry-Perot office.
The sensor installation method at large-scale power transformer folder place is put in a kind of optical fiber Fabry-Perot office of the present invention, and it includes:
