<p>Compressed air supply for the operation of a high-duty electrical circuit breaker includes in the pipe from the compressor to the air receiver a water separator, a two-way valve, an absorption filter and a non-return valve. The two-way valve is used to actuate a by-pass, which shunts this valve and the filter when shut, and which includes a non-return valve and a restrictor. This system of providing the required dry air is simple and achieves an automatic regeneration of the absorption filter.</p> |
