Description
Appointment:

Are intended for:
- inclusions and shutdowns of the deenergized sites of an electric chain which are energized;
- grounding of the disconnected sites by means of grounding conductors;
- expeditious connection of the reversible unit launched in the pump mode to the starting device - thyristor to the frequency converter at hydroheat - sink power plants;
- a zakorachivaniye of generators, generators - engines with the extinguished field of a rotor at electric braking of hydrounits of hydroelectric power station and pumped storage power plant;
- grounding of the sites disconnected from power supplies incremental - screened current distributors;

Design:

On a design disconnectors of the vertically cutting type also imeet one and triple - pole executions on the general frame.
Disconnectors consist of a socle (frame), basic insulators, contact system, traction insulators and grounding conductors (at their existence).
On a frame of the disconnector the power shaft with levers intended for operating by contact knives is located.
In the presence of grounding conductors on a socle of the disconnector, next to the drive, the mechanical blocking interfering inclusion of grounding conductors at the included main knives and vice versa is established.
The contact system of the disconnector consists of motionless contacts and mobile contact knives.
Contact pressure in axial and demountable contacts is carried out by springs.

Advantages:

In comparison with analogs disconnectors of the RRI series have the following advantages:
1. The disconnector frame made of monolithic electroinsulating material possesses high resistance to influence of environment, the mechanical and electric durability and accuracy of production.
The ledges executed in a special way on a frame carry out a role of insulators that allowed to exclude actually basic insulators and in general to increase reliability of the disconnector. Maladjustment of coaxiality between motionless contact and a mobile main knife of the disconnector as at analogs is excluded (because of unreliable connection of an insulator with a frame).
2. The rubbing knots have the small moments of friction and do not demand greasing during the between - repairs period of 10 - 15 years.
3. Knots and details from ferrous metals have corrosion - resistant coatings and do not demand their restoration to 20.. . 30 years of operation. Current carrying parts of the main knives and grounding conductors are covered with tin or nickel, other details - galvanic zinc.
4. Contacts of the main knives reliably work when heating with total rated current at an effective temperature of air of + 40 °C.
5. The disconnector with the drive has high factory readiness due to rational kinematic communication them with each other.
