CONSTRUCTION

The electrical system of the flame-proof mining switchgear is installed in the flame-proof housing. Housing has seven separate chambers. Housing design provides a degree of protection IP*4 and protects against electric arc of *5 kA for 0.2 s. Is installed on a chassis fitted with skids or wheels for transport to the place of installation of the switchgear on mine.

Is installed on a chassis fitted with skids or wheels for transport to the place of installation of the witchgear on mine.

The flame-proof mining switchgear consist of:

1. Chamber of connection terminals, designed to connect of the outflow cables

2. Chamber of disconnector, which is mounted disconnector with earthing switch with electrical drive, the station service transformer power control system, locks and visualization and three voltage transformers (optional) with fuses and switches for protecting transformer and voltage transformers.

3. Chambers of switch and earthing switch circuit I i circuit II, which are mounted vacuum contractor, current transformers, disconectors with earthing switch with the electrical drive.

4. Chambers of outflow terminals circuit I i circuit II, designed to connect of the outflow cables. In chambers are installed current transformers (Ferranti) operating with the controllers.

5. Chambers with control and protection elements.
