Switchgear with a modular optical monitoring system

A switchgear, comprising:

• an optical monitoring system without cameras for examining switchgear switching positions;
• an installation housing;
• a receptacle disposed in said installation housing:
• an encapsulated housing disposed in said installation housing, said encapsulated housing having a region with a first transparent window;
• at least one isolating switch accommodated in said encapsulated housing;
• an observation module disposed removably at or in said installation housing;
• an imaging system disposed in said observation module at or in said installation housing;
• a fiber-optic system leading from an outer side of said installation housing to said first transparent window;
• said fiber-optic system including at least one first fiber bundle having a first end and a second end for capturing an optical picture of said at least one isolating switch through said first transparent window and transmitting the optical picture to said observation module disposed at said first end with said imaging system;
• said fiber-optic system including at least one second fiber bundle having a third end and a fourth end;
• a light source disposed in said observation module, said light source emitting light to be guided from said third end to said fourth end in a region of said first transparent window and to be guided through said first transparent window;
• and
• a coupling module with a fixed coupling module part and a mobile coupling module part, said mobile coupling module part being fixed to said observation module, said fixed coupling module part being installed in said installation housing and fixed in said receptacle in said installation housing;
• said coupling module being disposed or configured to be disposed between said observation module on one side and both said first end of said first fiber bundle and said third end of said second fiber bundle on another side.
