Ants in SF6 switchgear

Postby ShakeyDave » Sat Sep 23, 2006 1:19 pm

Myself and one of my team had an annoying experience recently on an underground HV fault.
We opened the fuse chamber of an ABB SF6 Safelink unit to replace a blown air fuse. Thousands of ants emerged out of the workings of the unit and were a real pain to keep out of the fuse ports whilst performing a fuse change.
Anybody got any bright ideas on how to get a nest of ants out of an ABB SF6 Safelink switch unit without poisoning them or taking the unit apart?
Before you ask, ABB has not come up with a solution either as of yet. Cannot poison the little suckers as the formic acid in thier body's is corrosive and all those ant larve' will still be there. :?

Thats a tricky one could you use a air compressor? And force them off without killing them? We have problems with some of our ants here the hungry little pests eat the insulation off the underground cables.

A vacuum cleaner came to mind, but that wouldn't get them all. :)

I wonder if there is an ant attractant trap that could be used where they enter but don't exit.

Almost completely unrelated, I just got a midge magnet from America. This is a machine that trickles propane through a actalytic converter to crreate a warm plume of carbon dioxide. When biting insects get a whiff they follow it back to what they assume will be a tasty snack and instead get sucked into a net inside. haven't tried it yet.

One of those electric heat guns may do the trick or and LPG torch just toast them but I doubt the environmental officer will appreciate the idea....
