Detection device for on-off fault of power system optical fiber

Abstract

The invention relates to the technical field of optical fiber on-off detection equipment, and aims to provide a detection device for on-off faults of a power system optical fiber which can effectivelysolve the problem that existing detection devices for optical fiber on-off are single in function. The device comprises a fixed base. The fixed base is connected with a movable base through a slidingrod and is provided with a laser emission module on the upper surface. A laser transmitter is arranged on the laser emission module. A laser receiving module is arranged on the upper surface of the movable base. A laser receiving module is arranged on the laser receiving module. The laser emission module and the laser receiving module are respectively connected with a laser emission limiting plate and a laser receiving limiting plate through a bayonet. A threaded pipe is arranged on both the laser emission limiting plate and the laser receiving limiting plate. The detection device for on-offfaults of the power system optical fiber has the advantages that the on-off of the optical fiber can be detected, and detection of the optical fiber break point can also be used through cooperation ofthe laser emission module, the laser receiving module, and the threaded pipe, so as to improve the resource utilization rate.

Description

technical field [0001] The invention relates to the technical field of optical fiber on-off detection equipment, in particular to a power system optical fiber on-off fault detection device. Background technique [0002] An optical fiber (optic fiber) is a fiber made of glass or plastic that acts as a means of transmitting light. The transmission principle is 'total reflection of light', and the tiny optical fiber is encapsulated in a plastic sheath, allowing it to be bent without breaking. Usually, the transmitting device at one end of the optical fiber uses a light emitting diode (LED) or a laser beam to transmit light pulses to the optical fiber, and the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulse. In daily life, optical fibers are used for long-distance information transmission because the transmission loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers are coat...
