The socket plug reversive RSh-2 is intended for accession to the starting unit or actuators.
By means of couplings the reverse el is carried out. engines.
The socket consists of two main parts: the plug socket with six contact nests and a plug fork with six contact probes.
To clips of contact nests the ends of veins of the cable going from the starting unit, and are connected to clips of contact probes - the ends of veins of the cable going to el. to the engine.
CONDITIONS OF APPLICATION OF THE PRODUCT
3.1. Sockets are intended for application in underground developments of mines and buildings in which use of electric equipment performed by "RV" is allowed.
3.2. Climatic modification of sockets U category of placement 5 in accordance with GOST 15150-69.
3.3. Sockets can be operated in the following conditions:
— air temperature - from minus 10 to plus 35 °C
— relative humidity of air - (98 ± 2) % at a temperature (35 ± 2) °C;
— tension of network - to 1,1 Un;
— an operating mode - long;
— working position in space - any;
OBNSPECHENIYA'S MEANS OF EXPLOSION PROTECTION
7.1. Explosion proofness of the socket is provided with the conclusion of electric parts in a blast-tight cover which maintains explosion pressure in it and excludes transfer of explosion to the surrounding explosive environment.
7.2. Durability of each cover is checked at its production by hydraulic tests by pressure of 0,8 MPas.
7.3. In fig. 1 are shown:
— interfaces of details, obpespechivayushchy slot-hole explosion protection. These interfaces are designated by the word "Explosion" with the indication of parameters of explosion protection;
— marking on explosion protection;
— tension of intrinsically safe and intrinsically safe chains;
— blocking;
— ways of leak and electric gaps between current carrying parts.
In introduction devices current carrying parts of heteronymic phases are divided by the isolating partitions from an aminiplastics of MFV1, arc-resistant according to GOST 10345.1-78.
7.4. The Vzryvonepronitsayemost of input of a cable is reached by consolidation it by an elastic rubber ring.
7.5. Temperature of external surfaces of a cover is not above 60 °C.
7.6. Heads of screws of a persistent ring have a turnkey internal hexagon and are closed by a special cover which presses them and interferes with them to samootvinchivatsya.
7.7. Application of lock-nuts and spring washers warns from self-unscrewing of the current carrying and grounding clips.
7.8. The socket is made of the materials resistant to frictional sparking.
7.9. External plastic elements of the socket are made of materials which concerning accumulation of electrostatic charges do not exceed norms.
