During the last decades the modernization of the complete distributing devices which are in operation, is widely spread abroad. In our country this process is only starting and, besides economic expediency, it is caused also with the fact that replacement of the switch with the spent resource by the similar, is physically impossible (the spare parts are absent, the former supplier appeared "abroad", etc.).

Besides in conditions of the adverse economic situation the modernization of the complete distributing devices often remains unique means of increase of electrosupply reliability of consumers and reequipment of the substations equipment.

Modernization of the roll-out elements of the complete distributing devices of the following type:

K-XII, K-XIII, K-37, KRU2-10(KVE), KRU-500, KЗ-02, KRU2-10Б, CSIM1-10/350, K-Pe, k-Su, K-IV, K-VIU, KR10-U4, KE-6, KE-10, KRUE-6(10)V, ST 7, ST 9 vacuum switch BB/TEL-10.

Modernization of the complete distributing devices of the following type: K-104, K-204 EP, KM-1, KM-1F, KM-1M, KMV, KRUN-6(10)L, K-47, K-49, K-59 roll-out elements BE/TEL.

Modernization of the multipart cells of unilateral service of the following type: KSO-266, -272, -285, -292, -2U(M), -D13B, -KPOЗ, -2200, MKFV, cells from concrete or stone and complete distributing devices of outdoor setting of the following type: KRN-II, KRN-III, KRN-IV, KRN-10, MKFN, K-VI, S-164, S-204, S-191 vacuum switch BB/TEL-10.

The initial data for filling the report of inspection RU, RP, 3RU substations of the enterprises for reconstruction with the BB/TEL application.

1. To specify the full name of the reconstructed substation (distributive point) according to the example:

Region / Maintaining organization / Name of substation / voltage class

Example: Vinnitsa, Vinnitsa oblenergo Ltd., substation "Industrial" 110/10 kV

2. To present the one-linear circuit of electric connections 6-10 kV with the polling positions filling:

While filling polling positions it is necessary to specify the common positions for the distributing devices: rated voltage, estimated current K3 on multipart busbars, etc. And it is necessary to fill in the columns with specifications of the oil switches subjecting to replacement.

3. Under full reconstruction of the system R3 and A, it is necessary independently to choose and specify the type of the relays assumed to installation on the drawing.

4. Under keeping of previous system R3 and A fully or partially it is necessary to specify the circuit number on the drawing, according to the original project to copy the circuits and to attach to the present project as the appendix.

5. To specify on the drawing the operative power supply systems data: voltage type, voltage value, availability of filters, type of a source of an operative power supply. Under the reconstruction of the operative power supply system it is necessary to specify the type and parameters of again installed equipment (power supply cabinet).

6. To specify the connection load character: the high-voltage electric motor, lead-in, air-line, a reserve, etc.

7. It is necessary visually and under the factory plates to estimate the conformity of the cell offered to reconstruction, to the factory documentation on the given type of KRU (KSO).

8. It is necessary to check up the acquisition of the high-voltage cell. If necessary it is recommended to draw up a statement of technical inspection of the distributing device with the indication of cannibalized cells.

9. If necessary, it is recommended to make the outline plan of the equipment accommodation, cable communications lining. To specify the control cables extent between the panels (boards) and the conductors section.
