摘要： PROBLEM TO BE SOLVED: To provide a connector of which the conductive section is unlikely to be touched by a worker, and which can suppress influence exerted on a worker, etc. outside by an arc occurring during insertion/extraction work in an active state.SOLUTION: A positive electrode side pin plug 1 is provided with a pin side insulating protective member 15 on the tip end surface of a pin contact 14 which is a conductor. In a positive electrode side socket 2, too, a socket side insulating protective member 25 is provided on the tip end surface of a cylindrical socket contact which is a conductor. Because of this configuration, even when a worker, etc. try to directly touch the pin contact 14 from the tip end side of the positive electrode side pin plug 1, the worker is made to touch the pin side insulating protective member 15 first, and thereby prevented from touching the pin contact 14. The same is true of the positive electrode side socket 2. Further, since both of the contacts are provided with the insulating protective members on the tip end surfaces, even if an arc occurs during insertion/extraction of a connector in an active state, the risk of the arc jumping out of the connector can be reduced.

摘要： PROBLEM TO BE SOLVED: To prevent generation of an unintentional ground current in a DC power supply system provided with a voltage compensator which supplies a DC voltage from a power supply to a load by positive and negative power supply lines grounded through a resistor, and backs up a DC voltage supply to the load.
SOLUTION: In order to back up the decline of a DC voltage from a rectifier 2 to a load 3, the voltage compensator 5 is provided including a storage battery 10 having a grounded midpoint and power converters 11 and 12 composed of step-up/step-down choppers and connected to the positive and negative electrode sides of the storage battery 10. When the storage battery voltage Vb declines during power supply from the voltage compensator 5 to the load 3, each step-up/step-down chopper 14, 15 operates to compensate for the decline of the storage battery voltage Vb. Since voltages having the same level are output from the step-up/step-down choppers 14 and 15, the voltage between the ground point of the storage battery 10 and each power supply line 6, 7 becomes uniform, and the ground current is prevented.
