Polarized Resistor Drainage Station DRP-М1 serves to protect the metallic facilities and utilities against corrosion impact underground, in the areas with stray currents from rail DC transport (trams, tube, trains).
Features
DRP-М1-100, DRP- М1-300 and DRP-М1-500 have the following features:
- modernized heat characteristics of drainages;
- extended switch and flow of nominal current;
- low turn-on voltage;
- no need in external power supply source;
- parallel switch of diode-resistor sections for secure operation of drainage station DRP;
- measurement of the current running through drainage;
- a breaker switch in current draining circuit from an object;
- protection against overvoltages caused by atmospheric phenomena;
- step control circuit for nominal current: for DRP-М1-100 / DRP-М1-300 from 0.1 х I nom with step 0.1 х I nom; for DRP-М1-500 from 0.07 х I nom to I nom with step 0.07 х I nom.
Design Features and Operating Conditions
- Protection Category for current-carrying parts and against environment impact is IP34.
- Electric shock protection class is 1 (GOST 12.2.007.0.).
- It meets the fire safety requirements (GOST 12.1.004.).
- The cables are mechanically secured when connecting to the drainages.
- No rodents, reptiles and insects can get into the cable access holes.
- Metal body secures the device from mechanical damages.
- The body is covered with light powder polymer coating to increase corrosion resistance, to protect from atmospheric factors, to lower the heat from the sun.
- The devices can work up to 50,000 hours. Service life is 20 years.
- The locks of the outer door are vandal-proof..
DRP-М1 operates within the ambient temperature range — 45°С — +45°С, with the maximum relative humidity 98% (at +25 °С).
