Brushed electric motor (10), comprising an outer case (11), two brushes and further a rotor (30) having a first inner end (31) and a second outer end (32) which is inserted within the outer case (11). The brushed electric motor (10) is in particular usable in environments with a risk of fire or explosion or in presence of potentially explosive or flammable fluids, and comprises at least a filler element (20) made with a polymer based material which is positioned internally to the outer case (11) of said brushed electric motor (10) for minimize the free volume within the brushed electric motor (10) itself and for allow at the same time to maintain a high power and high performance characteristics of the brushed electric motor (10), by minimizing the possibility of triggering a burst or fire.


A circuit breaker with quick response and separation and a quick response and separation method for the circuit breaker. The circuit breaker comprises a breaking contact group (10) and a joint contact group (20). The breaking contact group comprises a movable breaking contact (11). The joint contact group comprises a movable joint contact (21). A movable contact limiting device (31) used for limiting moving positions of the breaking contact and/or the joint contact is arranged between the breaking contact group and the joint contact group. The quick response and separation method for the circuit breaker comprises a breaking and opening step, wherein the breaking contact reversely moves and is separated independently ahead of the joint contact, or the breaking contact and the joint contact reversely move and are separated at the same time. The breaking contact is adopted in the circuit breaker to replace a fixed contact in the conventional art, and when the circuit breaker needs to carry out opening and breaking operation, quick separation between the contacts is realized due to two-way separation action between the breaking contact and the joint contact, so that the electric arc phenomenon can be avoided or reduced, and the service life of the circuit breaker is prolonged.

The invention discloses a quick arc-breaking circuit-breaker, comprising two electrode contacts for switching on and switching off a circuit, and a plurality of partition plates arranged between the two electrode contacts and configured in such a way that, when the two electrode contacts are separated, the partition plates are inserted at the fastest speed between the two electrode contacts, to quickly break arc and stop burning. As the partition plates of the quick arc-breaking circuit-breaker are inserted between the two electrode contacts from different directions, the breaking and insulating speed is accelerated, the isolation and sealing effects between the two electrode contacts are enhanced, and the insulation and arc extinguishing effects of the circuit-breaker in working are thus improved. The circuit-breaker of the invention has a simple structure and a low manufacturing cost.

The present disclosure is directed to several embodiments or variations of a power generation system. Several of these variations use the same power generators and also include one or more prime movers that supply mechanical power to the generators. In a first embodiment of the power generation system, two single drive through-shaft generators adapted to produce electric power are configured to be driven by a common prime mover. In a second, alternative embodiment of the power generation system, a plurality of generators is arranged into first and second generator groups. Each of the first and second generator groups is operably associated with an independent motor, which allows the power output to be controlled via adjustment to the applied power of the independent motors.

A once-through steam generator comprises a duct having an inlet end in communication with a source of a hot gas; and a tube bundle installed in the duct and comprising multiple heat transfer tubes. The tube bundle has an economizer section, an evaporator section, and a superheater section. A steam separating device may be positioned between the evaporator section and the superheater section, wherein, as part of a wet start-up, hot water collected by the steam separating device is delivered from the steam separating device to mix with cold feedwater before it is introduced into the economizer section. A start-up module may be positioned in the duct near the inlet end, wherein, as part of a dry start-up, cold feedwater is delivered into the start-up module to generate hot water that is then mixed into the feedwater stream before it is introduced into the economizer section.
