Background

The existing load break switch, especially the load break switch with a strip-shaped switch shell, has the following problems:

firstly, mostly do not have fuse state detection, if need confirm the fuse state, need go to the field survey and look over, waste time and energy.

Two, current load break switch who has fuse state detection, its micro-gap switch also all sets up on the fuse, and when the user changed the fuse, the micro-gap switch needed to be taken off earlier, extracted the fuse again, installed micro-gap switch after changing the fuse again, and the operation is more complicated to need outage earlier before taking off micro-gap switch, if the user changed the fuse under the condition of not outage, had the potential safety hazard.

Third, in the conventional load break switch, there is mostly no phase separation plate between the terminals, and if a customer uses a large terminal or applies the load break switch to a high voltage scene (especially AC1000V or DC1500V), there is a risk of phase-to-phase short circuit due to an excessively short distance between the terminals or an insufficient electrical gap or creepage distance under the high voltage condition. Or, some current load break switches are equipped with the looks division board, all need customer's self-installation, do not have the fool-proofing function, if the customer does not adorn, when misloading or neglected loading, then have the alternate short circuit risk.
