<p>PURPOSE: To provide an elementary switch panel which is essentially small in size and easy to assemble. CONSTITUTION: Three circuit breaking poles 6, 7 and 8 are housed in a breaker enclosing device 1 for composing an enclosed and gas-insulated high-voltage switch panel. Pipe attachment appliances 11, 12 and 13, which are arranged at apexes of a triangle and through which leads 19, 20 and 21 are introduced, are formed on the circuit breaker enclosing device 1 as a whole so as to face outward. In order to realize a small-size switch panel, the circuit breaking poles 6, 7 and 8 are arranged on a straight line in this order and are supported via only the leads 19, 20 and 21.</p> |
