Plug conducting pedestal in flakes secondary circuit, rotary plug-in type protection is in investment state in flakes；When rotation insert in flakes two without
The plug insertion of metal contact is in flakes in two jacks with metal contact of pedestal, rotation at this time insert in flakes two touched without metal
The plug of head shields the secondary circuit of pedestal in flakes, and rotary plug-in type protection is in flakes exits state；When rotation is inserted in flakes
Four plugs are not inserted into two jacks with metal contact of pedestal in flakes, at this time two of the pedestal in flakes of pedestal in flakes
Jack with metal contact exposes, and can just measure secondary circuit.
As a further preferred solution, it is provided with magnetic pole on the bottom end of the support mounting hole, bolt, it can be simply fast
Prompt changes the state of protection in flakes.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
(1) a kind of rotary plug-in type protection includes that pedestal and rotation are inserted in flakes in flakes, is equipped with 8 jacks on pedestal altogether, rotation is inserted in flakes
Using cross form, so that protection has three state in flakes, is investment respectively, exits and measure.It puts into, exit state
The closing of lower bottom base jack, avoids the risk of electric shock；
(2) it is protected in flakes using rotary plug-in type entirely in entire protection screen, protective loop can only pass through support under measuring state
Jack measures, and is avoided when measuring one by one because accidentally touching adjacent risk in flakes caused by intensively installing in flakes；
(3) there are mounting holes among protection in flakes is fixed on the base by bolt, can will be protected when not used for a long time in flakes
It removes；
(4) static contact is arranged in both ends in flakes for protection, by rotating in contact inserted base jack, realizes corresponding state
Transformation, it is simple and quick.
Detailed description of the invention
