Acquisition device with optical fiber protection, full optical fiber current transformer and installation method

Abstract

The invention relates to a collecting device with an optical fiber protecting function, a full-optical-fiber current transformer and a mounting method. The collecting device comprises a circuit board, an optical device, a device protecting shell and a fiber coiling box which is fixedly arranged on the outer side face of the device protecting shell and can be opened and closed. The circuit board and the optical device are fixedly arranged in the device protecting shell which is provided with a first optical fiber hole. The device protecting shell is provided with an extending part corresponding to the side where the fiber coiling box is placed. The extending part is provided with a second optical fiber hole which is provided with a pressing connector. Wholly-output optical fibers of the circuit board and the optical device extend out from the first optical fiber hole of the device protecting shell and are coiled in the fiber coiling box. Optical fibers output by the fiber coiling box are guided out from the second optical fiber hole and the pressing connector. The collecting device is simple in structure and can reduce the needed mounting space effectively, and the collecting device has the advantages of being convenient to maintain, high in safety and attractive in appearance.

Description

technical field [0001] The invention relates to the technical field of current transformers, in particular to an acquisition device with optical fiber protection in an all-fiber-optic current transformer, an all-fiber-optic current transformer using the collection device, and an installation method for the all-fiber-optic current transformer. Background technique [0002] The current sensor / transformer is an important device for relay protection and electric energy metering in the power system. It is used to measure the current in transmission and send the measured current to the measuring instrument and relay protection device. The long-term stability, reliability and safety of current transformers are closely related to the safe and stable operation of power systems. Traditional electromagnetic current transformers have some insurmountable difficulties in principle, such as ferromagnetic resonance, magnetic saturation, limited frequency band, etc., and there are potential ...
