High Voltage Circuit Breaker Dealers in Aurangabad

The Load Break Switch is a disconnect switch that has been designed to provide making or breaking of specified currents. Load Break Switch is accomplished by addition of equipment that increases the operating speed of the disconnect switch blade and the addition of some type of equipment to alter the arcing phenomena and allow the safe interruption of the arc resulting when switching load currents. Disconnect Load Break Switches can be supplied with equipment to provide a limited load switching capability. Arcing horns, whips, and spring actuators are typical at lower voltages.

Safety and reliability have been a challenge in today’s coal fired boilers at thermal power stations. FOURESS, in technical consultation with a few discerning customers have developed the perfect solution to the pressing problem of effective isolation of PF mills. This has been done with the ingenious concept of TWIN SEAL FLAP (TSF) Isolator, which guarantees 100% sealing efficiency for safe access to on-load maintenance of PF mills. Majority of the coal fired boilers in India use guillotine gates as Isolating equipment for PF mills. This technology has become out dated owing to its ill-equipped provisions. As such, Maintenance Engineers on the site face a host of problems, some of which are as follows : Existing guillotine gates do not use an effective sealing system. This results in leakage of gas to the downstream. High velocity coal laden gas further aggravates the leakage making it virtually impossible for maintenance personnel to take up on-load maintenance. Thus an additional blanking plate becomes essential. The entire operational area gets polluted due to transit leakage during operation of the guillotine gate. There is frequent failure of cylinder seals owing to heat radiation during operation.
