Central cabinet energy storage intermediate relay

What are the characteristics of small intermediate relays?

Abstract. This paper presents a comparative analysis of technical characteristics and designs of small intermediate relays from various manufacturers. The following main characteristics of relay are considered: operation and release values; weight and dimensions; power consumption; time parameters; reliability characteristics.

How many relays can be installed in RPA cabinets?

On average, 6-10 or even more relays can be installed in RPA cabinets. The Russian electrical and energy enterprises in their products most widely use imported relays from Finder (Italy), Schrack (Austria), Relpol (Poland) as there is no competitive SIR produced in Russia.

What is a small intermediate relay (Sir)?

Small intermediate relays (SIR) are widely used in relay protection and automation (RPA) cabinets of power facilities. Their functions are to control relatively powerful loads with relatively low switching durability, provide galvanic isolation between input and output circuits, and increase noise immunity.

What is intelligent component cabinet installation mode?

When the intelligent component cabinet installation mode is adopted, the secondary system is compact and takes a small footprint, which can optimize the secondary circuit structure. But this method puts forward high requirements for the device’s environmental adaptability. 10.3.1.3. Station area protection control configuration

How to monitor the mechanical state of an isolated circuit breaker?

The online monitoring of the mechanical state of the isolated circuit breaker mainly includes the closing speed, the time, the closing coil current waveform, and the number of times the circuit breaker operates. The closing speed is the key parameter reflecting the state of the mechanical characteristics.

How a monitoring device can improve the reliability of isolated circuit breaker?

According to the requirement of visualization of equipment status, the deep integration of the online monitoring device is realized in the design and manufacture of the isolated circuit breaker. The equipment status is monitored online, and the equipment reliability is improved for the intelligent function of the equipment.
