COMPLETE HIGH-VOLTAGE SWITCHGEAR Russian patent published in 2013 - IPC H02B7/06 H02B11/12 H02B13/65 G06F15/16 

FIELD: electricity.

SUBSTANCE: in compete high-voltage switchgear consisting of separate metal cabinet separated into technological compartments, having the possibility of single-sided and two-sided service and containing switching device, microprocessor protection and protection of main circuits, high-voltage contactor is used as switching device. Microprocessor protection has the possibility of providing simultaneous operation with sensors of temperature, level, dry stroke, sensors of flooding, speed and pressure and possibility of integration to automatic system for commercial measurement of power consumption and automatic process control system. Input and outgoing lines are made in the form of collecting buses or cable connection. Protection of main circuits is made in the form of arc protection device and unloading valves.

EFFECT: improving protection, monitoring and protection of high-voltage synchronous and asynchronous motors owing to increasing number of start-stop cycles, and frequency of their actuations.
