Beneficial effect of the present invention is:

1. integrated engineering cost of the present invention is low, easy for installation, the time is short, can carry out dismounting and change to the blade be corroded in use procedure and wear and tear timely fast, construction period is short, improves production efficiency, reduce maintenance cost, be convenient to carry out inspection and maintenance to power distribution cabinet.

2. alleviate blade integral deadweight, coordinated fixing, reduce the use cost of material, adopt split splicing structure by self-locking structure, installing/dismounting is all very convenient, has saved human cost.

3. the first blade and the second blade are respectively equipped with first protruding and the first groove mutually agreed with, two blades can be made to be combined into one more closely, can not slippage, its security performance more.
