Telfer is controlled using the YAVZ3125 power brand box manufactured by the Oktyabrsky plant.

Attraction pumps are controlled using brand control boxes

Ya5114-2974UKhL4, Ya51143274UKhL4, Ya5114-2874UKHL4, Ya511043274UKHL4 manufactured by Kazanelektroshchit in place, in addition, remote control from the nurse's office is provided for all pumps.

All control equipment of power electric units has manual controls (start/stop) and is located within visibility in relation to controlled equipment.

All power electrical equipment is powered by IWGng cables laid along existing and designed cable and construction structures. Cable approaches to electrical power equipment are protected by corrugated pipe.

For emergency disabling of attractions there is an emergency disabling button located on the wall in the pool bowl room.

10.3. Electric lighting

Electrical lighting of the water treatment plant is performed in this detailed documentation.

Lighting and stock factors are selected on the basis of SNiP 230595 "Natural and artificial lighting."

To illuminate the premises, a system of general uniform lighting is adopted.

The design provides for working and emergency lighting. Illumination of working surfaces from emergency lighting is not less than 5% of normalized illumination from local lighting.

The lighting type is as follows:

lamps with fluorescent lamps ALS.PRS 418, IP54;

illuminator with filament lamp NPB 1108, IP44;

The board of a working light of ShchO2 is powered from ShR2, and emergency board ShchOA2 is powered from I LIE.

Lighting is controlled by switches installed in the filters room.

Power lines are executed by three-vein cable VVGNG 3х1.5 (phase - L1, the zero worker - N, zero protective - RE conductors) to board ShchO2 and ShchOA2.

Group electric lighting networks are made with three-core cable VBGng 3x2.5 (phase - L1, zero operating - N, zero protective - PE conductors).

Group networks of emergency electrical lighting are made with three-core cable VBGng 3x1.5 (phase - L1, zero operating - N, zero protective - PE conductors).

Protective grounding of metal bodies of lamps should be performed by connection to grounding screw of EP-conductor housing.

Main indicators of lighting plant:

Installed power - 0.98 kW, including:

working lighting - 0.58 kW,

emergency lighting - 0.4 kW.

10.4. Electrical safety

The main grounding bus (GPC) is located in the RTD (PE bus). GWN is connected to external grounding conductor. To perform the main system of potential equalization, the following elements are connected to the GWN (external grounding electrode):

- ventilation system air ducts;

- metal pipelines of water supply and sewerage at the entrance to the building;

- metal building structures of the building;

- metal electrical structures;

- metal housings of process equipment.

The connection is made by welding of strips 40x4, 25x4 mm.

All newly installed process electrical equipment, control stations and lighting equipment are grounded by TNS system. As conductors of protective grounding (PE), a special 3rd (5th) conductor is used.

To perform additional system of potential equalization, all open and third-party conducting parts are connected to each other at the same time:

- enclosures of boards, cabinets;

- metal pipelines;

- metal building structures of the building;

- metal electrical structures;

- metal housings of process equipment.

Connection is made by welding of strip 25x4 mm.

The band of the main potential equalization system is welded to pins inserted into the wall at a height of 0.2 m from the level of the clean floor.

The grounding line is painted with PF115 enamel yellow-green (yellow stripes on green background at a distance of 150 mm from each other).
