HIGH-VOLTAGE EQUIPMENT MODULE

摘要

PROBLEM TO BE SOLVED: To provide a high-voltage equipment module that prevents a pair of main relays from being simultaneously in a conductive state due to vibration applied from the outside when it is required to maintain a cut-off state. SOLUTION: A pair of main relays 2 is incorporated into part of a high-voltage circuit so as to be respectively connected with the positive-electrode side and the negative-electrode side of a high-voltage power supply. The high-voltage equipment module 1 is composed by mounting the pair of main relays 2 to a common casing 5. Each main relay 2 has a fixed contact 21 fixed to a body and a movable contact 22 arranged so as to be movable with respect to the fixed contact 21. A conductive state is formed by bringing the movable contact 22 into contact with the fixed contact 21, while a cut-off state is formed by separating the movable contact from the fixed contact. A pair of main relays 2 is arranged so as to prevent each moving direction K of each movable contact 22 from being in parallel with each other. COPYRIGHT: (C)2009,JPO&INPIT
