Specific embodiment
Embodiment 1:
Referring to shown in attached drawing 1-4, a kind of inflatable cabinet load switch, including bracket 1, bracket 1 be equipped with that pairing uses the
One static contact 2 and the second static contact 3, moving contact 4, shaft 5, T-type contact 6 and arc-chute 7, on-load switch is three-phase electricity herein
Gas connection, i.e. it is mutually electrical that the first static contact 2, the second static contact 3, moving contact 4, T-type contact 6 and arc-chute 7 cooperatively form one
Connection, since the structure in every phase is consistent, therefore only describes a wherein phase herein.It is set in shaft 5 there are three moving contact 4, by turning
Turn axis 5 makes the other end of moving contact 4 and the second static contact 3 form on-off switch, one end of moving contact 4 and the first static contact
2 rotation connections.
First static contact 2 and the second static contact 3 be connected and fixed by static contact and insulation support 8 with bracket 1, herein the two
Between connection structure it is consistent, therefore the connection structure of the second static contact 3 with static contact and insulation support 8 is only described herein.
8 top surface of static contact and insulation support is equipped with limiting slot 81, positioning column 82, fixation hole 83 and wiring fixing groove 84,
