<p>PROBLEM TO BE SOLVED: To make the voltage presence directly extract from the low voltage terminal of a voltage detection insulator as the installation of airtight terminals and the connecting work of the lead wires are omitted. SOLUTION: An enclosed container 2 contains an electrical machinery like a conductor 5, which is connected to the high voltage terminal 11A of the voltage detection insulator 11 to detect the voltage presence on the conductor 5, and the low voltage terminal 11B of the voltage detection insulator 11 is sticked out of the prescribed container 2. The voltage detection insulator 11 has an insulating flange 11C between the high and low voltage terminals. The voltage detection insulator 11 is fitted to its hole of the enclosed container 2 by using the flange 11C without losing its airtightness.</p> |
