DISCONNECTORS OF SAFETY LOCKS OF THE D0 SERIES
Disconnector of safety locks VLD01:
The disconnector of safety locks is a device with replaceable fusible inserts. Allows to use operational advantages of systems of protection of D0:
- a possibility of replacement of the failed safety lock without risk of a touch to current carrying parts;
- reliable contact is provided with system of spring clips;
- the indicator of operation of a safety lock is visible in both provisions of the disconnector (1 or 0).
Principle of operation of the VLD01 disconnector: The cell of safety locks of D01 92A-6A, 10A, 16A) carries out function of the lever which is switching off (including) the disconnector. The centering insert can be replaced only with use of special I instrumentat. The disconnector is intended for mounting on the tire TH35.
- modular execution;
- a possibility of sealing both in included and in the switched-off state;
- the design of plugs allows to clamp the conductor and the tire at the same time;
- quantity of poles: 1p, 1p+N, 2p, 3p, 3p+N;
- type of loading of AC22B;
- breaking capacity of 50 kA;
- indication of a condition of a safety lock.
Disconnectors of safety locks STV D02:
The disconnector of a safety lock STV D02 is a device with replaceable fusible inserts for protection of an electrical equipment. Allows to use operational advantages of systems of protection of D0 (similar to VLD01).
Principle of operation of the STV D02 disconnector: for replacement of a fusible insert it is necessary to pull the disconnector handle down (that leads to a rupture of an electric chain), then to put forward a cell and to take out a fusible insert. After promotion of a cell with a fusible insert the visible break in a circuit is provided. It allows to use given the device as the main safety lock or the main switch in distributing devices. For calibration of safety locks the special centering insert is used. In the disconnector also use of safety locks of D01, using the special adapter is possible. The disconnector is mounted on the tire TH35.
- replacement of the failed safety lock without risk of a touch to current carrying parts is possible;
- reliable contact is provided with a design of spring clips;
- possibility of supply lead both from above and from below;
- a possibility of sealing in included and in the switched-off state;
- type of loading: AC22B, AC23B(35A), DC22B;
- otklyuchayuashchy ability of 50 kA;
- isolneniye: 1p, 1p+N, 2p, 3p, 3p+N;
- range of currents from 2 to 63A;
- use of the disconnector with time cut-outs gives the chance to reach necessary selectivity.
