1.1. The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC with the bypass of connected to the gap of the power supply of the SWG cell and the drive motor. HVFC with bypass allows you to enter into work and remove from work HVFC and at the same time start and operating the drive motor. Taking the HVFC out of service for repair is carried out together with the drive engine.
2.0. The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with vacuum switches. HVFC is connected to the open circuit of the power supply circuit of the driving motor and the feeding cell, while the SESAC cells make it possible to commission and release the HVFC from work or repair and at the same time start and operate the drive motor. The high-voltage circuit is assembled by means of vacuum switches.
2.1. The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with manual disconnectors. HVFC is connected to the open circuit of the power supply circuit of the driving motor and the feeding cell, while the SESAC cells make it possible to commission and release the HVFC from work or repair and at the same time start and operate the drive motor. The high-voltage circuit is assembled by means of manual disconnectors. The scheme is applicable for electric motors with power up to 2000 kW inclusive.
2.2. The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with manual disconnectors. HVFC is connected to the open circuit of the power supply circuit of the driving motor and the feeding cell, while the SESAC cells make it possible to commission and release the HVFC from work or repair and at the same time start and operate the drive motor. The high-voltage circuit is assembled by means of manual disconnectors. The scheme is applicable for electric motors with a capacity of more than 2000 kW.
3.0 The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with vacuum switches, the number of which depends on the number of drive motors. The scheme allows you to perform start-up and frequency control of drive motors from HVFC, start-up of drive motors from the SWG supply cells through the bypass. For HVFC operation, it is necessary to have a free cell in the supply sections of the SWG (or several cells in different sections of the SWG). The presence of SESAC cells allows you to enter into work and remove from work or repair HVFC, even if the SWG supply cell powering the HVFC is not switched to the repair position, perform a selection of electric motors to be started and frequency controlled. HVFC is connected to the existing power supply system and does not require replacement of the existing power cables laid from the power supply cells of the switchgear to the drive motors. This scheme is intended for the use of HVFC with power of up to 2000 kW inclusive.

For HVFC operation, it is necessary to have a free cell in the supply sections of the SWG (or several cells in different sections of the SWG). The presence of SESAC cells allows you to enter into work and remove from work or repair HVFC, perform a selection of electric motors to be started and frequency controlled.

3.2 The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with vacuum switches, the number of which depends on the number of drive motors. The scheme allows you to perform start-up and frequency control of drive motors from HVFC, start-up of drive motors through the bypass. The presence of SESAC cells allows you to enter into work and remove from work or repair HVFC. To power the HVFC, a power cell of one of the motors is used, to which a section is added consisting of two SESAC cells with vacuum switches. One of the SESAC cells powers the motor bypass, the other - HVFC. The remaining engines operate on the network according to the existing scheme and do not require replacement of the existing power cables laid from the power supply cells of the switchgear to the drive motors.
3.3 The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with vacuum switches, the number of which depends on the number of drive motors. The scheme allows you to perform start-up and frequency control of drive motors from HVFC, start-up of drive motors through the bypass. The presence of SESAC cells allows you to enter into work and remove from work or repair HVFC. To power the HVFC from two sections, power cells of two engines are used in different sections, to which 2 sections of SESAC are added. Each section of SESAC consists of two SESAC cells with vacuum switches. One of them provides power to the motor, the second - to HVFC. The remaining engines operate on the network according to the existing scheme and do not require replacement of the existing power cables laid from the power supply cells of the switchgear to the drive motors.
4.0 The scheme of the electric motor frequency control system "PRONEGA" is implemented on the basis of HVFC and SESAC cells with vacuum switches, the number of which depends on the number of drive motors. The scheme allows you to start and frequency control of the drive motors from HVFC, direct start on the bypass from the corresponding SESAC. For HVFC operation, the presence of free cells in each of the supply sections of the switchgear is not required. It is not required to control the power supply cells of the SWG for switching to the bypass motor power supply circuit from the network. The presence of SESAC cells allows you to enter into work and remove from work or repair HVFC (when taking HVFC out for repair, you must release the power supply SWG cell in the repair position), perform a selection of electric motors to be started and frequency controlled. The scheme does not require modification of existing SWG cells in terms of control circuits, electromagnetic and operational locks. The scheme allows the start of the selected motor from different supply sections of the SWG.
