LATCH ARRANGEMENT FOR BREAKER FOR GAS-INSULATED SWITCHGEAR

摘要

PURPOSE: A latch arrangement is provided to allow maintenance and repair to be easily performed by adjusting position of latch wheel through a simple operation even when the latch wheel is assembled. CONSTITUTION: A latch holder(20) fixed to a bottom plate, and a latch pin(25) is coupled in such a manner that an end of the latch pin is inserted into a coupling hole(20a) of the latch holder and the other end of the latch pins is inserted into a through hole formed at the bottom plate. A latch(24) is coupled to the rotatable to the latch pin, and a latch spring(26) has an end coupled to the latch so as to elastically rotate the latch. A spring driver(27) is coupled such that the spring driver supports the other end of the latch spring and adjusts elasticity of the latch spring. A driver holder(28) is arranged to suppress the spring drive from rotating in a reverse direction by the force of the latch spring. A C-ring(29) is coupled to be attachable/detachable to/from the rear end of the latch pin such that the latch pin is correctly positioned.
