SAFETY SYSTEM OF HIGH-VOLTAGE ELECTRICAL EQUIPMENT OF ELECTRIC TRAIN Russian patent published in 2020 - IPC B60L3/00 B61C3/00 H05K5/02 

FIELD: transportation.

SUBSTANCE: invention relates to the vehicles electrical equipment. System of safety of high-voltage electric equipment of electric train includes protective enclosures and interlocks and electromechanical key lock. Protective guards and interlocks are made in the form of enclosures of electric containers. Electromechanical key interlocking represents a combination of a lock working switch, keys issuing devices, lock mechanisms and keys to locking mechanisms providing for serial access to electrical equipment during its maintenance. Electrical equipment interlocking is combined. Some part of electric equipment is equipped with electromechanical key lock. Some part of electric equipment is equipped with electric interlocks and fixing hatches for maintenance of hazardous zones of containers with electromagnetic devices. Some part of electrical equipment that does not require frequent access is equipped with electric interlocks and screw connections. Electric circuits of electric interlocks and fixing electromagnetic devices are integrated into electric circuits of electromechanical key lock.

EFFECT: technical result consists in providing the possibility to use electrical equipment with different types of interlocks.
