TSV36M313

Power transfer through the TSV36M313

The TSV36M313 transmits electrical energy through contact rings and brush assemblies. This allows the rotating part of the main rotor to receive power while the rotor is in motion. The most heavily loaded part of the unit is the anti-icing power circuit, where the current load differs by phase. Because the unit carries high current, the condition of the brushes, contact rings, insulation, terminals and mounting surfaces directly affects system reliability.

TSV36M313 in the blade anti-icing system

One of the main functions of the TSV36M313 is power supply to the heating elements of the main rotor blade anti-icing system. In this circuit, the unit transmits three-phase AC power at aviation frequency. The passport specifies 208 ±10.4 V and 400 ±20 Hz for the three-phase circuit. The current load is not equal across all phases: phase B is rated higher than phases A and C. This detail is important during inspection and troubleshooting of the anti-icing system.

Contour lights and control circuits through TSV36M313

Besides the main anti-icing circuit, the TSV36M313 also carries power for blade contour lights and low-current control or monitoring circuits. The contour light circuit uses single-phase AC at low voltage. The control and monitoring buses operate from the DC aircraft network. These circuits are lower in current than the anti-icing circuit, but they still depend on stable brush contact and correct electrical continuity through the rotating assembly.

Aircraft use of TSV36M313

The TSV36M313 is used on helicopters with electrically powered main rotor blade equipment, including Mi-8, Mi-17, Mi-171, Mi-14, Mi-24 and Ka-32 types, depending on configuration. Its exact role on a particular helicopter depends on the installed anti-icing system, lighting equipment and rotor electrical layout. For replacement, the unit should be checked against the aircraft parts catalog, electrical diagram and passport data, not only by general designation.

Brush set and service points of TSV36M313

The passport комплектность includes the TSV36M313 slip ring unit and two brush types. The brush set is important because wear, burning, contamination or poor seating of brushes can cause heating, unstable contact, voltage drop or loss of a circuit. During maintenance, technicians normally inspect contact rings, brush holders, brush condition, terminals, insulation, signs of overheating and free mechanical condition of the rotating interface.

Supply and identification of TSV36M313

When ordering the TSV36M313, the full designation should be stated, and the required helicopter type should be specified if known. It is also useful to confirm whether the unit is supplied complete with brushes and passport. For aviation supply, the key points are passport availability, storage condition, category, repair status, completeness and compliance with the required aircraft configuration. The passport data should be used as the main reference for voltage, frequency, current load, weight and комплектность.
