This series of permanent-magnet synchronous gearless traction machines is directly driven by a low-speed, high-torque, 3-phase permanent magnet synchronous motor, and has the advantages of low energy consumption, low noises, no pollution, and little maintenance.
These traction machines can be arranged for providing upward traction or downward traction, and have remote manual brake release function. Wrap angle of the traction machines can be only 180°.

The main function:
The “Technical Measures for Preventing Capacitor Installations from Being Accidents†stipulates that, for high-voltage shunt capacitors, the capacitance of a single capacitor in a capacitor bank should be regularly measured. It is recommended to use a measurement method that does not remove the connection cable, and to avoid the occurrence of bushing due to the disassembly and connection of the connection cable. The failure of the casing to leak oil due to stress.
Specially developed for the substation site to measure the capacitance of a single capacitor in parallel capacitor banks and SCV devices, it has the following functions:
* Do not take off the wire and measure the capacitance of the parallel capacitor or the collective capacitor.
* Do not take off the line to measure the inductance of the reactor and the wave trap.
* Do not remove the transformer's inlet capacitance, generator inlet capacitance, etc.
* With a parallel (discharge) resistance measurement function * can compensate for the low output voltage of the capacitor table and cause a low failure detection rate.
* Simultaneous display of voltage and current waveforms and phases, calculation of measured capacitor power loss.
By using flat frame structure with three mounting surfaces, this series of traction machines can be installed on bottom floor or any middle positions or on the top of shaft way.
One hundred test card - fully automatic capacitive inductance tester due to the use of standard capacitors, synchronous capacitor sampling technology, can be subject to power supply voltage fluctuations; plus the measurement process is fully automatic, to avoid the error caused by manual operation, so it has a stable Good, repeatable, accurate and reliable features.
