PRESSURE SENSOR FOR GAS SWITCH, GAS BLAST LOAD-BREAK SWITCH PROVIDED THEREWITH AND GAS PRESSURE DETECTING METHOD FOR GAS-BLAST LOAD BREAK SWITCH
PRESSURE SENSOR FOR GAS SWITCH, GAS BLAST LOAD-BREAK SWITCH PROVIDED THEREWITH AND GAS PRESSURE DETECTING METHOD FOR GAS-BLAST LOAD BREAK SWITCH
PROBLEM TO BE SOLVED: To miniaturize a pressure sensor for a gas-blast load-break switch at a low cost and simplify the structure of an air-tight seal portion by manufacturing the pressure sensor for the gas-blast switch to detect gas pressure in a sealing container for the gas-blast switch without using a bulky and expensive metal bellows. ;SOLUTION: A mounting bracket 1 for a pressure sensor A for a gas-blast load-break switch is secured to a sealing container 9 for the gas-blast switch so as to encircle a detection hole 91. To the mounting bracket 1, a mounting base 2 is secured. A rubber diaphragm 3 is held between the mounting base 2 and a wall 90. To the mounting base 2, an operating member 4 is secured in a movable manner to operate a display 8. The operating member 4 is energized to the side of the diaphragm 3 with a coil spring 44 and put in contact with a gas-proof section 31.;COPYRIGHT: (C)1999,JPO
