Claims (5)

1. 1. A device for distributing electrical energy, comprising a housing containing a power equipment chamber with a block of power switches, busbars and a two-position disconnector-earthing switch, a cable chamber, wherein the vacuum chambers are located in the block of power switches, the conductive buses are electrically connected to the vacuum power switch, the cable chamber is configured to connect a load, the two-position disconnector-earthing switch is connected to the grounding circuit, characterized in that it contains a block intended for testing the cable line, electrically connected to the cable line through the two-position disconnector-earthing switch, and a block of the power switch, configured to have access to the cable line for testing the cable line, containing a metal plate connected to the grounding circuit directly and through the two-position disconnector-earthing switch, and containing an arc protection device.
2. 2. The device according to paragraph 1, characterized in that the unit intended for testing cable lines is designed with the possibility of connecting the testing device to one of the phases, while ensuring grounding of the other phases in the same testing device.
3. 3. The device according to paragraph 1, characterized in that the unit intended for testing cable lines is designed and placed in such a way that testing of cable lines is carried out without access to the cable compartment and contact with cable lugs.
4. 4. The device according to paragraph 1, characterized in that the mutual arrangement and circuit design of the power equipment chamber is designed in such a way that the two-position disconnector-earthing switch is electrically connected to the busbars, to the power vacuum circuit breaker and to the cable line testing unit, with the elements of the cell grounding device integrated into it.
5. 5. A method for testing a cable line, which consists of gaining access to the phase of the cable line being tested through a unit intended for testing the cable line, using a device for testing the cable line by removing the grounding metal plate connecting the phases located in the unit intended for testing the cable line, connecting the cable line testing device to one of the phases, and grounding the remaining phases.
