2.4G wireless transmission method) connection, by way of wireless communication, solves the installation question of attitude transducer, make it
Influence for disconnecting switch internal structure is minimum, will not influence the regular job of disconnecting switch.The installation position of attitude transducer
Transmission parts should be reduced as far as possible between disconnecting switch moving contact by setting；Attitude transducer should be mounted on the position as close as possible to contact
It sets, guarantees that attitude transducer more really reflects the location status of disconnecting switch moving contact.Posture detecting unit 2 is being kept apart
Pass answers trigger position to measure when acting, and movement should stop measuring when stopping, and can be by the location information of disconnecting switch with wireless
Transmission mode is sent to reception device 1.The strong electric discharge that arcing generates when posture detecting unit 2 is able to bear disconnecting switch divide-shut brake
And high-intensity magnetic field influences, it will not be because of the harassing and wrecking of any external electromagnetic or external force mistaking signal.Posture detecting unit 2 is installed on high electricity
