バータ装置の保護装置。An inverter section consisting of multiple power transistors connected in a bridge configuration is connected to the AC power supply through the normally closed contacts of the relay and the rectifier circuit, and the power transistors in the inverter section are connected to the base via the base drive circuit. In an inverter device, a control circuit configured to transmit a control signal is connected, and a plurality of power transistors are controlled on and off at appropriate times by the control signal to transmit an output from an inverter section. The AC side input coil wound around one side leg of the leg iron core is inserted in series with the DC side input coil wound around the other side leg of the three leg iron core on the output side of the rectifier circuit. A current detector has an output coil wound around its legs, and a burden resistor is inserted between both ends of the output coil of this current detector, so that when the voltage between the terminals of this burden resistor becomes larger than the reference voltage, an output is generated. an overcurrent detection circuit that is connected to the AC power source via a transformer and outputs an output when the input voltage becomes larger than the reference voltage; and a voltage detection circuit that is arranged near the power transistor. A temperature detection circuit that is connected to the temperature sensor and outputs an output when the ambient temperature of the power transistor becomes higher than the set temperature of the sensor, and a temperature detection circuit that is connected to these detection circuits and receives the output of at least one detection circuit as an input. 1. A protection device for an inverter device, comprising: a stop circuit configured to send out a signal to prevent the control circuit from sending out a control signal and a signal to open a power source.
