Medium, each element（Generally comprise breaker, disconnecting switch, earthed switch, voltage transformer, current transformer, bus,
Arrester, cable termination etc.）By wiring requirement, it is sequentially connected and forms a whole.
Insulator is the customary insulation control in 110KV combined electrical apparatuses, and it is usually to be made of isolation material, is then existed
The embedded metal insert in centre is such as conducting rod etc.In order to ensure that the ground connection property of electrical equipment is good, need to connect on general insulator
Special ground wire, ensure that the ground connection property of electrical equipment is good, need to connect special ground wire on general insulator, so installing
When it is not only very inconvenient, and easily occur due to being grounded not sufficiently good the problem of causing combined electrical apparatus powered.
Utility model content
Be solve existing combined electrical apparatus insulator using the installation inconvenience caused by ground connection, easily occur therefore
Hinder the problem of powered, the utility model provides a kind of 110KV combined electrical apparatuses insulator, and the insulator passes through in discoid base
Seat edge sets aluminium flange circle to replace ground connection, not only facilitates installation, has also ensured earthing effect, it is not easy to event occurs
Hinder it is powered, meanwhile, the presence of aluminium flange circle also makes the insulator have certain electromagnetic shielding action, improves combined electrical apparatus
Security performance.
The utility model is that technical scheme is used by solving above-mentioned technical problem：A kind of 110KV combined electrical apparatuses are with absolutely
Edge, including disk-shaped base, the central area of disk-shaped base convex to form cylindrical boss to the both sides of its thickness direction,
Metal conducting bar is nested with the center of cylindrical boss, surrounding cylindrical boss on the disk-shaped base is provided with arc
Connected in star, the passage of some insertion disk-shaped bases is distributed with arc groove, around the edge of the disk-shaped base
Aluminium flange circle is fixedly installed, the medial surface around the aluminium flange circle has groove, and the groove is with surrounding disk-shaped base side wall
Projection be engaged and realize being fixedly connected for disk-shaped base and aluminium flange circle.
In the utility model, the both ends of the metal conducting bar protrude from the both side surface of cylindrical boss.
In the utility model, the arc groove is arranged on an arc-shaped recess bottom on disk-shaped base surface, and arc
Side wall of the groove close to disk-shaped base edge protrudes from the bottom of arc-shaped recess to form fin.
In the utility model, between the cylindrical boss and disk-shaped base by the convex arcwall face that is connected and under
Concave arc surface is formed and seamlessly transitted.
Beneficial effect：The utility model by setting aluminium flange circle to replace ground connection at disk-shaped base edge,
Not only facilitate installation, also ensure earthing effect, it is not easy to break down powered, meanwhile, the presence of aluminium flange circle also makes this exhausted
Edge has certain electromagnetic shielding action, improves the security performance of combined electrical apparatus.
