VACUUM RECLOSER
РВ-БЭМН


   Purpose
For automatic disconnection of a damage part of a network, remote control,
automatic power backup input and automatic reclosure.

   Field of application
10 кВ aerial lines with one-way and two-way power supple.

   Features
A recloser constantly controls current and voltage, performs relay protection
functions, by means of a GSM modem may be integrated in Smart Grid system
procuring an opportunity to separate a damaged, as well as manual and computer-
aided dispatcher control. Its application makes it possible to reduce time
for detecting, localizing and removing an electric line damage and, therefore,
improve reliability of power supply for customers and reduce operational costs.

  Configuration
• A switching unit with built-in current transformers.
• An auxiliary transformer.
• A control cabinet with МР750 current directional protection terminal (or
МР550 current indirectional protection terminal), GSM modem, battery and
a heater.
• An instrumentation cable with switching plugs for connecting the cabinet to
a reclouser.
• A feed cable for connecting an auxiliary transformer to the cabinet.
• Excess-voltage suppressors.
• A mounting kit.
Against order РВ-БЭМН reclouser may be equipped with a commercial accounting
unit with the following configuration:
• a cabinet of measuring transformers;
• an accounting cabinet with a power meter and GSM modem.Purpose
