For achieving the above object, the utility model is achieved through the following technical solutions:
On-load switch and fuse protection combination insulating cylinder, the flat-shaped quadrangle sleeve that this insulating cylinder is formed in one, this insulating cylinder has the chamber of an accommodating earthed switch, main switch and isolating switch, and its inside has main switch arc control device, and the contact jaw of these main switch arc control device stretches out in aforementioned cavity and be positioned at corresponding main switch correspondence position; Described insulating cylinder is extended with fuse outlet casing tube, bus cable sleeve pipe and observation window, described fuse outlet casing tube, bus cable sleeve pipe and observation window be arranged in parallel, described bus cable sleeve pipe is extend out in chamber and with earthed switch position and is adapted by a conducting rod that is L shape, described fuse outlet casing tube is connected with main switch arc control device by a conductive plate that is S shape, described fuse outlet casing tube, bus cable sleeve pipe and observation window all with insulating cylinder one moulding by casting.
Further, spacing A=197mm between described fuse outlet casing tube and bus cable sleeve pipe, and spacing B=230.5mm between bus cable sleeve pipe and observation window.
Further, corresponding isolating switch position, described chamber bottom surface has a through hole, and this through hole is shoulder hole, and described chamber is communicated with this through hole, the accommodating and syndeton of formation isolating switch.
Further, corresponding earthed switch position, described chamber bottom surface is built-in with a bus safety ground contact, and this contact is embedded in insulating cylinder insulating material.
Further, described observation window is a pass column structure, and this observation window outside is provided with screw thread.
Further, the internal diameter C=55mm of described observation window.
Further, the height of described insulating cylinder is H=603mm.
It is solid material by cable bus leading body and cable plug head, ground connection open the light contact, main switch disjunction arc control device, high voltage isolator that the utility model adopts epoxy resin, and all sealings gather together, and band cut-offs the break contact observation window of contact.
