Description

The PCh-50M U3 manual drive is designed for operating the main and grounding blades of indoor disconnectors with a voltage range of 6-10 kV.

Design:

The drive consists of the following main components: a worm gear reducer, a drive with a block lock, a handle mounted on the drive shaft, and a tube connecting the drive shaft to the worm shaft. Self-lubricating bushings support the worm and shaft. The KSA-type devices can be connected to the drive. To connect the disconnector control lever, there is a rod with a plate and clamps on the output shaft of the worm wheel.

The drive cabinet enclosure is made of stainless steel and is securely protected against adverse environmental effects throughout its entire service life.

Advantages

Reduced emergency shutdown time;
High reliability (10,000 switching cycles);
Electromagnetic interlocking to ensure the correct connection sequence.
