The plastics cutting ferrule that described isolating switch moving contact maintenance cover special the is pulled moving contact of can tightly holding, form a stable entirety with pressing plate and holder, stability when fully having ensured moving contact dismounting and having installed, eliminate without specific purpose tool and caused moving contact surface damage potential risk, improved repair quality.
Preferred further, holder comprises the first holder and second holder of the structure that links into an integrated entity, the first holder is arranged on the second holder upper end, the first holder and the second holder are cylindrical, and the internal diameter of the first holder is 120mm, and external diameter is 150mm, be highly 100mm, the internal diameter of the second holder is 180mm, and external diameter is 200mm, is highly 30mm.Facilitate fixed plastics cutting ferrule.
Preferred further, plastics cutting ferrule comprises the fixed head of plastic clip cylinder and plastic clip cylinder lower end, and pressing plate is annular, and pressing plate is fixed into one through plastic clip cylinder and the fixed head of plastic clip set upper side by connecting bolt.Plastic clip cylinder is through the interior ring of annular pressing plate, convenient fixing.
Preferred further, the plastic clip cylinder of plastics cutting ferrule is cylindrical, on plastic clip cylinder sidewall, vertical slot is set, and the diameter of plastic clip cylinder is 120mm, is highly 100mm, and the internal diameter of pressing plate is 140mm, and external diameter is 170mm.Make discontinuity in plastic clip cylinder, easy disassembly.
Preferred further, the diameter on embedded chassis is 180mm, on embedded chassis, external screw thread is set, and embedded chassis and holder are threaded connection.Easy to connect.
Preferred further, torque spanner Special fixing price fixing, the diameter of torque spanner Special fixing price fixing is 80mm, torque spanner Special fixing price fixing and embedded chassis are fixed by set bolt.
Preferred further, holder, holder handle, pressing plate, embedded chassis and torque spanner Special fixing price fixing all adopt steel alloy.Draw materials conveniently, intensity is high, and greatly improving can durability, convenience and fail safe.
The beneficial effect that the present invention has is:
Described isolating switch moving contact maintenance cover special is pulled and can fully be overcome GW16 type isolating switch moving contact and disassemble the problems such as inconvenience, can avoid maintainer to use rough power to cause moving contact surface and screw thread damage, the security reliability of raising personnel operation, reduction operation intensity, saving operating time raise the efficiency.Wherein, the critical pieces such as holder, holder handle, pressing plate, embedded chassis, torque spanner Special fixing price fixing can adopt alloy steel material, draw materials conveniently, and intensity is high, and greatly improving can durability, convenience and fail safe.The plastics cutting ferrule moving contact of can tightly holding, form a stable entirety with pressing plate and holder, stability when fully having ensured moving contact dismounting and having installed, eliminate without specific purpose tool and caused moving contact surface damage potential risk, improve repair quality, more safe and efficient while making maintainer's operation.
