One end of base is installed with resin insulating barrier, and the resin insulating barrier is fixed inside one end of rubber-covered base to be inserted
It is connected to cable.
Preferably, the outlet column and it is mounted on firm banking into the bottom of terminal, and outlet column and logical into terminal
Firm banking is crossed mutually to fix with protective housing using bolt.
Preferably, threaded securing bores are offered on the firm banking.
Preferably, the current transformer is provided with six, and is mutually electrically connected respectively with outlet column and into terminal.
Preferably, the outlet column and the specification into terminal are identical with composition material.
Preferably, the external stability of the arc-chutes is provided with insulation booth.
Compared with prior art, the beneficial effects of the utility model are：
1st, the side end face bottom of the utility model protective housing is mounted with breaker, effectively can solve and prevent and is small
The generation of current earthing or leak current fault so that the safety compared during demarcation switch use, voltage transformer, which is installed on, to be protected
The inside of protective case body, effectively make use of space so that the volume of demarcation switch greatly reduces, easy to the transport of demarcation switch
And installation, greatly save cost.
2nd, taper top plate is mounted with the top of the utility model protective housing, birds can be effectively prevented and opened in boundary
Shut and nest, it is therefore prevented that unexpected and dangerous generation, outlet column and into terminal using rubber-covered base and resin insulating barrier
Combining form, more traditional porcelain knob binding post are compared, and are more adapted to carry, damage is not easily caused in handling process.
