Described fixed contact conductor (1) is in L-type, and comprise the conductor (11) at middle part, conductor (11) upper end arranges smooth installed surface (13), and described installing hole is arranged on installed surface (13), and is formed and the connection of outlet casing tube (4) by electric-conductor; Conductor (11) lower end arranges the sheet edge of a knife (12), and the described sheet edge of a knife (12) contacts with isolation switch (3).
Described fixed contact holder (2) includes fixed pedestal (21), pedestal full skirt (22), flap limit (23), flap limit full skirt (24) and contact cladding (25);
Described flap limit (23) is formed the sheet edge of a knife (12) from both sides coated, flap limit, both sides (23) extends to form described contact cladding (25) obliquely, contact cladding (25) forms coated to described conductor (11), described fixed pedestal (21) is formed by pedestal full skirt (22) and described flap limit (23), contact cladding (25) connection.
Described flap limit full skirt (24) be arranged on flap limit (23) inner side and and isolation switch (3), fixed contact conductor (1) depart from setting.
The utility model has the advantages that: the utility model passes through integrated design, by direct for contact conductor sealing in contact holder, the fixed contact of integration to eliminate in traditional ring main unit isolating switch required to be flexible coupling, the parts such as thermoplastic sleeve pipe, insulator, product structure is simple, effectively prevent contact resistance greatly to the problem of major loop Resistance Influence, unique cluster parachute and flap limit structural design, fully ensured its good, reliable insulation property.Under the prerequisite guaranteeing properties of product, enormously simplify product structure, reduce volume, also substantially increase reliability when product runs simultaneously.
The fixed contact of the utility model integration is directly installed on ring main unit housing by the installing hole on contact holder.The contact holder both sides of epoxy resin one moulding by casting are provided with flap limit, further increase the reliability of phase insulation.The contact holder of epoxy resin one moulding by casting has good electrical insulating property, corrosion resistance, thermal endurance, resistance to wear and outstanding impact resistance.
