摘要： PROBLEM TO BE SOLVED: To provide a cabinet in which a door can be locked without fail by the simple mechanism that the door can not be closed when a hook turns downward by mistake. SOLUTION: Only a metal piece 17 for prevention of downward-turning is added. The metal piece 17 is rotatably journaled to a stopper 12 for limiting a movement of the hook 11. When the metal piece 17 rotates and stops at a rotational position, a pin 17d deviates from a rotation route of the hook 11 to allow the hook 11 to rotate freely. When the metal piece 17 rotates and stops at a downward-turning preventive position, the pin 17d appears on the rotation route of the hook 11 so that the hook 11 may be prevented from turning downward. When the door of cabinet is closed, a hook receiver 21 of a cabinet body comes into collision so that the door may not be closed when the downward-turning is prevented. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the reverse tide by promptly cutting off an inverter from a distribution system at the time of cutting off the linkage, and to eliminate need for equipment increase and counter measures for a private power generation system used by respective consumers. SOLUTION: This protection device protects consumer equipment 200 which supplies power generated by the private power generation system 203 to a consumer load 201 connected to the distribution system through the inverter 202. This system comprises a voltage detector 101 for detecting the voltage of the distribution system, a judging part 104 for detecting that the consumer side equipment shifts to an individual operation at the time of cutting off the distribution system based on the power amount of the detected voltage, and a load input device 102 connected with the distribution system and for connecting load resistor R with the AC side of the inverter 202 by closing a make and break contact 103. It is thus possible to close the make and break contact 103 with a judged signal outputted from the judging part 104 when the consumer side equipment shifts to the individual operation, and connect the load resistor R with the AC side of the inverter 202 to stop operation by short-voltage relay function of the inverter 202.
