摘要： A fault on the generator can be detected with the use of a simple arrangement. The output of the generator 12 which has multi-phase winding and is driven by an engine 11 is rectified and then converted by an inverter 133 into an alternating current at the frequency of a system before interconnected to the source of the system. After the engine 11 is started, the direct current voltage Vdc is monitored with a first fault monitor 40. When the direct current voltage Vdc rises up to a predetermined level, a connector relay 135 is closed. As the output of the inverter 133 is increased, the interconnection with the system source is enabled. After the interconnection, the direct current voltage and the output of the inverter are monitored with a second fault monitor 43. If the direct current voltage drops down to below the predetermined level before the output of the inverter reaches a rated level, the canceling and re-interconnection is repeated. Then, when the direct current voltage remains below the predetermined level after the re-interconnection, it is judged that the generator 12 has a fault such as a line breakage in the windings disconnection.

摘要： A grid-type engine generator apparatus which can prevent reduction in the operational efficiency due to the stop motion of an engine at the cancellation of the interconnection and minimize loads exerted on the startup device for the engine. A network protector is provided for generating a fault signal when detecting a fault on the network source. Upon receiving the fault signal, an interconnection relay is opened to cancel the interconnection and simultaneously, a timer is started. The cancellation permits the engine to run with no load. When the fault signal is maintained until the setting duration of the timer is timed up, a time-out signal is released to stop the engine. On the other hand, when the fault signal is eliminated by canceling the cause of the fault before the setting duration of the timer is passed, the interconnection relay is closed to establish the interconnection again and the timer is reset.

摘要： A generator apparatus such as in a cogeneration system has a controlling power supply energized with its generator output with giving no adverse effect on the waveform of its output. An inverter 13 is provided for converting an alternating current output of the engine generator 10 into a direct current and returning back by the action of its inverter circuit 133 to an alternating current of a predetermined frequency which is then connected to a power supply system 14. While the engine 11 remains not actuated, a power received from a joint between the inverter 13 and the power supply system 14 is rectified by a rectifier 141 and transferred to the controlling power supply 140. When the engine 11 is started, the power at the input of the inverter circuit 133 is transmitted to the controlling power supply 140. As the voltage at the input of the inverter circuit 133 is set higher than that at the power supply system side, the energization of the controlling power supply 140 with the power at the input of the inverter circuit 133 can automatically be selected after the start-up of the engine.

摘要： A first primary winding N11 of a transformer 1 is connected with a commercial power source 30 via a transistor Q1, and a second primary winding N22 of the transformer 1 is connected with a backup battery 31 via a transistor Q2. An electric power on the second primary winding N12 is output for a controlling apparatus. When a voltage of the commercial power source 30 is larger than a predetermined value, a backup stopping circuit 10 turns off a LED 9 and stops the transistor Q2. The second primary winding N22 is connected with input terminals 14, 15 as a power source for charging a battery 31. While the transistor Q2 is stopped, an electric power for the battery is output from the second primary winding N22. Since the LED 9 turns on at the time of electric power breakdown, the electric power for the battery is stopped.

摘要： An operation controlling apparatus for a passenger operated machine such as a tractor, snowmobile or the like. The apparatus includes an engine cut-off mechanism which terminates engine operation if an operator is expelled from the machine seat for a pre-determined time. Relatively short, intermittent periods of displacement of an operator from the seat, such as when travelling over rough or bumpy terrain, will not terminate engine operation. After emergency engine stoppage, the apparatus requires the machine be placed in a start waiting state, for instance by disengaging the clutch or when the transmission is placed in neutral, before the engine can be re-started.
