Radioavionica JSC has active designed and introduced modern power supply installations of Interlocking system since 2002 year. Nowadays Radioavionica JSC is leader in this direction – more than 350 Combined Uninterruptable Power Supply Plant (CUPSP) are operated on Russian railways. Our systems are installed on high-speed lines Saint-Petersburg-Moscow and Saint-Petersburg-Buslovskaya, where are moving Sapsan and Allegro.
Creating new developments and orienting on customer’s requirements our company is adhered to the principles taken as the basis during its foundation. Quality and safety are the main our values.
Our components suppliers for these systems are: ABB, GE DE, Hakel, Michael Riedel, Omron, Powernet, Elster and others. The service life of CPSP is about 25 years thanks to using modern technical solutions and good-quality components.
We are ready to offer you the wide range versions of CPSP based on uninterruptible supply units. The versions of CPSP are designed for modern microprocessor-based and relay-based interlocking systems and also combined systems.
Additional to current catalogue for designing CPSP you should use the technical solutions: "Power supply of Automatic block signal system with voice track circuits and central arrangement of equipment, microprocessor (ABTC/ABTC-EM) based on uninterruptible supply units for track line Saint-Petersburg – Moscow and technical references for designing of Giprotranssignalsvyaz and VNIIAS.

COMMON FEATURES OF COMBINED UNINTERRUPTIBLE POWER SUPPLY PLANT RADIOAVIONICA JSC
All versions of Combined Uninterruptible Power Supply Plant have functional features:
Connect of three independent feeders
Connect of three independent feeders of the external power supply and automatic load switching on correct feeder according to the parameters of it input voltage to the accepted standards. Diesel-generator set (DGS) could be used as the third feeder. It is possible to connect four feeder lines.
Two operation modes of ABP
The automatic backup power switching scheme could operate as in the mode prevalence of one feeder so in the mode of the equal feeders, which increases the effectiveness operation depending on conditions of the external power supply.
Guaranteed power loads
Providing for power supply to guaranteed lighting, conditioning systems and heating systems, modules DGS and communication devices auxiliary from commuted feeder (ABP exit).
Uninterrupted power loads
Providing for power supply to loads from Uninterruptible Supply Unit (USU) during autonomy time when feeder’s voltage is disappeared and mismatched.
Galvanic isolation of signaling loads
Galvanic isolation of signaling loads is provided from external power supply using input isolating transformer. Isolation of separate power poles of Signaling system from each other is provided with switch cabinets and impulse power suppliers. Herewith the DC power backup is based on the principle n+1.
Connection with existing systems of technical diagnostic-and-monitoring (STDM)
Continuous monitoring of operation CPSP in real time and connection with existing STDM on railways is provided. For CPSP-M is realized inbuilt diagnostic system.
Surge protection
Surge protection of input and output power circuits is realized. For these aims is designed multi stage protective system using surge protection device (SPD).
Personnel protection using Residual-current device
Protection of personnel from the lesions of electric via residual-current (RCD) in the lighting and the household loads.
High reliability and simplicity of maintenance
due to minimization of components and simplification of power switching circuits, control and monitoring.
Fire resistance construction
