Why choose Auto-reclosing switchgear

When the overhead line fault is cleared, the circuit breaker is closed in a short time, which is called reclosing.

Because most of the overhead line faults are transient or temporary, reclosing is one of the self-restoring power supply methods commonly used in operation.

It can be concluded that reclosing is a functional requirement, which can be achieved by two ways:

1, Circuit breaker plus relay protection, Actually the China standard Recloser is a VCB with closing function protection relay.

2, Reclosure ie. Auto recloser. Which is IEC/ANSI/IEEEC standard auto recloser.

The advantages of using auto-reclosing switchgear are as follows:

1. Saving the comprehensive investment of substation

2. Improving the success rate of reclosing

3. The maintenance work is small

 

What is diffierent between china standard recloser and IEC/ANSI/IEEEC standard auto recloser.

Rockwill also offer China(GB) standard autto recloser, which is capability of SCADA system, Ready for GPRS/GSM/WIFI/BULETOOTH communication.

General say, the GB standard auto-reclosing switchgear (China standard Recloser or GB recloser) is come from USA auto recloser version and redesign and simple it according to china grid standard.

The GB standard auto-reclosing switchgear is actual a combinated type reclosing-VCB.

So GB standard auto recloser is only a auto-reclosing switchgear, which is not complete function, poor precision, less relay protections, poor logics, small measuringrange, timing limitation,etc..It is not proper auto recloser for aplication in IEEE/ANSI/IEC standard network.
