RZA of the substation equipment of 35-110 kV she2607 157
- Customer pickup,
- Courier
- In detail
Application
It is applied to control of RPN electric drives at regulation of coefficient of transformation.
-
Structure
Contains two identical sets. Sets are executed on the basis of terminals of the BE2502 A0501 series. Sets realize the ARKT functions, provide automatic maintenance of tension, manual regulation of tension, expeditious switching of regulation and change of a setting on tension, blocking of RPN.
-
Principle of action
The automatic regulator of coefficient of transformation carries out automatic maintenance of tension in the set limits and manual regulation of tension, blocking of work of RPN at failure detection of the RPN drive and blocking of RPN from external signals.
-
Additional opportunities
In cases ShE2607 157 the possibility of independent service of sets is provided.
-
Features
Food of a case is carried out from chains of operational direct or alternating current.
