Description
Technical Field
The invention relates to an optical fiber access operation and maintenance instrument for a digital transformer substation, and belongs to the technical field of optical fiber access operation and maintenance instruments.
Background
With the increasing development of optical communication technology, relay protection communication physical transmission channels applied to power systems have been developed from past power carrier channels and digital microwave signals to optical fiber channels. Compared with the characteristic that the signal quality is unstable due to the fact that a power line carrier channel and a digital microwave signal are easily affected by climate change (such as wind, frost, rain, snow, thunder and lightning) and the like, the optical fiber channel has the characteristics of strong anti-interference capacity, wide transmission frequency band and low attenuation, becomes the first choice of a relay protection physical transmission channel, and is widely applied to actual work. In the connection equipment for communication with a large number of running optical fibers, a large amount of attenuation and interruption problems can occur in the running process. Such as poor contact of the optical port of the switch and unreliable fusion of the flange optical fiber.
These problems may not be found during construction. But the damage is increased after the operation for a long time, so that the equipment alarms and the optical fiber is prompted to break. At this time, the operation and maintenance personnel need to go to the site for fiber maintenance.
For example, the intelligent terminal is connected to the protection device through the optical fiber, the optical fiber behind the flange is connected with the protection device through the multi-stage switch. The luminous loss of protection device is tested from intelligent terminal one side, very trouble.
Firstly, a light pen is required to be used for lighting to detect whether the channel is normal. The fiber loss is then measured with an optical power meter. When the flange plate reaches the equipment end, one end of the flange plate is provided with an effective light source, and the other end of the flange plate is not provided with a light source, so that the test of bidirectional communication cannot be carried out. The spare fiber has no effective light source and cannot be subjected to attenuation test. The luminous pen and the optical power meter can only test the on-off and the light attenuation of one optical fiber in a matching way. If the damage of a plurality of optical fibers needs to be tested, the corresponding multiple times of testing time is needed, and the working efficiency is extremely low.
